ROSEMONT, IL, NOVEMBER 13, 2017 -- Emerson announced today a major upgrade of its Appleton™ Mercmaster™ LED series, the most trusted LED luminaries for harsh industrial and hazardous environments. Building upon legacy features and setting an even higher bar for lighting versatility, the new Mercmaster Generation 3 LED offers four light distribution patterns, seven lumen output levels, expanded color temperature options, and a wide choice of replaceable globes and mounts.

"Today's announcement is a continuation of our aggressive strategy to make harsh and hazardous LED luminaires more versatile than ever before and to help Electrical and Design Engineers give their clients energy-efficient, low maintenance lighting with uniformity and comfort at the lowest total cost of ownership," said Ellen Helm, Manager Appleton Lighting, Emerson. "The Mercmaster Generation 3 LED is highly configurable so it will meet the most demanding task and general lighting requirements, making it a single luminaire solution for new and expansion projects, as well as HID retrofits."

Engineered to provide long lasting, maintenance-free lighting, the enclosed and gasketed luminaires withstand harsh industrial environments without compromising reliability. Delivering a compartmentalized, durable design for minimizing the effects of elevated ambient temperatures, this luminaire's single-piece driver housing features separate sections for the terminal block and driver to ensure thermal efficiency; making both installation and wiring easier and promising a long luminaire life. Additionally, the Mercmaster Generation 3 LED's silicone rubber gaskets seal out moisture, dirt and dust, staying flexible and withstanding high temperatures, while the Extra-High Hinge provides additional protection against accidental ballast housing disengagement during installation or maintenance. Its rugged and corrosion-resistant design is rated for Class I, Division 2 and Class II hazardous locations, marine and wet locations, and is also certified for ATEX/IECEx Zone 2 - 21 and 22 to provide a globally-rated, lighting solution for all harsh industrial and hazardous illumination needs.

Suggested applications are oil refineries, petrochemical facilities, chemical plants, power generation plants, and other areas where flammable gasses and vapors may be present. Non-hazardous models of the Appleton Mercmaster Generation 3 LED are also available and can be used in locations where severe weather conditions, excessive moisture, dirt, dust, corrosive atmosphere or where high ambient temperatures are encountered.

UNMATCHED VERSATILITY

Thanks to the versatility of the Mercmaster Generation 3 LED, hard to illuminate areas such as walkways, wide passageways or decks, no longer need to suffer from poor light levels and uneven uniformity.

For example, the luminaire's secondary optics are engineered to create four unique types of light distribution patterns (Type I, Type III, Type V, or Type V Wide). Specifically designed to meet customer's needs, these light distribution patterns maximize fixture spacing, while minimizing the number of total fixtures needed and improving uniformity. As a result, overall project cost is dramatically reduced and employee safety, a critical concern in a hazardous location, is improved. Light distribution pattern versatility is especially important in greenfield and brownfield projects demanding luminaire flexibility due to tough to illuminate spaces and the variety of lighting needs.

In addition, the Mercmaster Generation 3 LED offers four replaceable globe options of Clear Polycarbonate, Diffused Polycarbonate, Clear Glass, and Prismatic Glass to provide application versatility. These high-quality globes help to diffuse glare, reduce hot spots, soften illumination, and increase fixture adaptability.

Seven lumen outputs levels, ranging from 3,500 to 17,500 Lumens (HID Equivalences of 70W to 600W) allow for mounting height and illumination level flexibility. By providing a selection of lumen levels, the Mercmaster Generation 3 LED helps engineers achieve precise foot-candle levels to meet target illumination levels. Expanded color temperature options of warm 3000K, neutral 4000K, and cool 5000K CCT assure the preferred color of light for any working environment.

A new, larger variety of mounting hoods offers the convenience to hang luminaries how and where lighting is needed most. With the Mercmaster Generation 3 LED's six choices of mounting hoods engineers no longer have to compromise on fixture placement. Wall, pendant, ceiling, and stanchion choices are available to make installing lighting around cabling, pipes and process equipment as easy as possible.

SMART RETROFIT FOR HIDs

Retrofitting HIDs with the Mercmaster Generation 3 LED luminaires ensures important maintenance and energy cost-savings, and can utilize competitor mounting adapters. With a service life of over 100,000 hours and a virtual maintenance-free design, coupled with the convenience of instant-on lighting and superior color rendering, the luminaires are a smart retrofit lighting solution. Most importantly, LED solutions deliver energy savings of up to 70% when compared to HID alternatives.

Vaisala's Optimus monitors transformer oil for the presence of moisture and seven different gases. By tracking real-time levels of hydrogen, carbon monoxide, carbon dioxide, methane, ethane, ethylene and acetylene, it gives asset owners a comprehensive understanding of the condition and health of a transformer, enabling them to make informed proactive maintenance decisions.

While many DGA systems available in the market source equipment and sensors from different manufacturers, the infrared sensor technology used in the Optimus has been developed in-house by Vaisala, benefitting from decades of industrial measurement expertise. This integrated approach, using only Vaisala-manufactured sensors and equipment, ensures optimal performance regardless of operational conditions.

In addition, the Optimus DGA Monitor's installation process is simple, and the unit is designed and delivered to enable asset owners to install and bring the device online independently and in under two hours. Once installed the device delivers reliable results in real-time through a browser-based user interface.

Most significantly, Optimus uses vacuum gas extraction and hermetically sealed and protected optics to completely eliminate the false alarms of the kind that frequently afflict on-site DGA systems. Optimus ensures high quality gas selectivity through its use of vacuum gas extraction, which operates regardless of oil temperature or gas pressure, and by employing spectral scanning to aid selectivity.

The robust and durable device has components and piping that are made of stainless steel and aluminum, features a magnetic gear pump and valves, and relies on no consumables, which would require servicing or replacing. With a practical browser-based user interface, the device has no need for additional software.


Reducing Lifetime Costs Across Transformer Fleets

"DGA analysis has long been accepted as one of the most effective means of assessing transformer condition," said Teemu Hanninen, Product Manager at Vaisala. "At Vaisala, we recognized that there was room to improve the reliability, usability and lifetime costs of the existing devices, and we decided to take on the challenge. With its proven durability and sensors protected from contamination, Optimus has shown that it can deliver reliable and accurate data."

Commenting on site visits Vaisala has carried out around the world, Hanninen added: "We have received a lot of positive feedback from those customers who have already received and installed their units - and as we're anticipating strong demand for Optimus in 2018. The comments have shown that the technology and capabilities offered by Optimus are really needed. Optimus has the potential to revolutionise the transformer monitoring industry."


The next opportunity to learn more about Vaisala's power offering will be at Euro TechCon 2017 in Glasgow, UK on November 13-15, and at Low Carbon Networks & Innovation Conference in Telford, UK between December 6-7.

Saskatoon, Saskatchewan, Canada, November 8, 2017

Cameco (TSX: CCO; NYSE: CCJ) announced today that due to continued uranium price weakness, production from the McArthur River mining and Key Lake milling operations in northern Saskatchewan will be temporarily suspended by the end of January 2018 and that the company’s annual dividend will be reduced to $0.08 per common share in 2018.

“With the continued state of oversupply in the uranium market and no expectation of change on the immediate horizon, it does not make economic sense for us to continue producing at McArthur River and Key Lake when we are holding a large inventory, or paying dividends out of proportion with our earnings,” said Tim Gitzel, Cameco’s president and CEO. “We regret the impact these actions will have on our workforce and other stakeholders and are doing what we can to cushion it while ensuring the long-term sustainability of the company. We believe these actions will help shield the company from the nearer term risks we face and will benefit all our stakeholders for their continued patience and support of our strategy to build long-term value.”

As a result of the suspension, the workforce at the operations will be reduced temporarily by about 845 workers (560 employees and 285 contractors). About 210 workers (160 employees and 50 contractors) will be retained to maintain the facilities in safe shutdown state.

We expect our share of the costs to maintain both operations during the suspension to range between $6.5 and $7.5 million per month. However, some of the items affecting these costs won’t be known until the operations are actually shutdown. More details will be provided in our fourth quarter results which will be released in February 2018.

Cameco plans to meet its commitments to customers from inventory and other supply sources during the suspension, which will be reviewed on an ongoing basis until inventory is sufficiently drawn down or market conditions improve. The duration of the suspension and temporary layoff is expected to last 10 months.

As we have previously indicated, we will continue to evaluate the optimal mix of our sources of uranium supply to feed into our contract portfolio, which could see us make further changes to our inventory position, production profile or purchasing activity.

Cameco will also review its corporate support activities for McArthur River and Key Lake operations, which may result in temporary workforce reductions at corporate office.

Uranium prices have fallen by more than 70% since the Fukushima accident in March 2011 and remain at unsustainably low levels. Cameco has been partially sheltered from the full impact of weak prices by its portfolio of long-term contracts, but those contracts are running out and it is necessary to position the company today to generate cash flow if prices do not improve.

Cameco has committed sales volumes of 28 to 30 million pounds in 2018. Using inventory to help meet contract commitments now allows Cameco to draw down its inventory without suffering a loss by selling at low market prices. It also avoids the risk of holding excess inventory valued above market prices on its balance sheet if prices remain low.

This measure is consistent with other actions Cameco has implemented over the past five years as part of a deliberate and disciplined strategy to strengthen the company in the long term. We have reduced supply, avoided selling into a weak spot market, resisted locking-in long-term sales commitments at low prices, and significantly reduced costs.

To decrease costs, we suspended production at the Rabbit Lake operation, stopped development and curtailed production at our US operations, reduced workforce across all our sites including head office, changed air commuter services for operations in Saskatchewan, changed shift schedules at two Saskatchewan sites, and downsized corporate office functions including a consolidation of our global marketing activities.

As discussed in our third quarter 2017 MD&A, year over year, average unit cost of sales (including depreciation and amortization) is down 13%, our cash production costs are down 10%, and direct administration costs are down 20%. Planned capital expenditures for 2017 are expected to be 26% lower than in 2016.

“To date, we have made good progress in reducing costs but unfortunately given the continued market weakness, more needs to be done”, said Gitzel. “We can’t control the market so our focus is on positioning the company to weather the continued low uranium prices and have uncommitted, low-cost supply to deliver into a strengthening market.”

In addition, Cameco’s board of directors has determined that the company’s annual dividend in 2018 will be $0.08 per common share, a reduction of $0.32 per common share on an annual basis. Further, the board has approved a change in the dividend payment schedule to an annual payment instead of quarterly. This change does not impact the quarterly dividend, announced on October 27, 2017, of $0.10 per common share payable on January 15, 2018, to shareholders of record at the close of business on December 29, 2017.

November 7, 2017

To enhance milling performance on ISO S materials, cutting tool and tooling system specialist Sandvik Coromant is introducing a series of end mills featuring unique geometries and grades. The CoroMill® Plura HFS (High-feed Side Milling) ISO S cutters deliver reliable and productive results on workpieces made from titanium and nickel-based alloys, bringing benefits to both aerospace engine and frame applications.

To help address the predicted growth in the aerospace industry in the coming years, the CoroMill® Plura HFS range comprises two end mill families optimized for titanium alloys, and one for nickel alloys. As chip evacuation and heat are specific challenges when machining titanium, Sandvik Coromant has developed a solid version for normal chip evacuation conditions, and another featuring internal coolant and a new cooling booster (patent pending) for optimum swarf and temperature control.

The end mills for titanium are available in GC1745 grade, which is based on a tough, fine-grained (sub-micron), cemented-carbide substrate with sharp, controlled edges for very tough milling operations. Furthermore, a new, multi-layer coating that contains silicon provides excellent wear resistance and low thermal conductivity. The geometry of the cutters is based on a six-flute concept with no center cut and uneven tooth pitch. Additionally, the core dimension has been optimized for higher stiffness in titanium alloys, while the corner radius, rake angle and relief are all designed specifically for machining these challenging materials.

For nickel alloys, grade GC1710 is deployed, which also features sharp, controlled cutting edges. A hard, wear-resistant, fine-grained substrate is optimized to resist high working loads when machining hard, highly adhesive, work-hardened materials such as aged Inconel 718. Here, a new coating produced with innovative HIPIMS (high power impulse magnetron sputtering) technology also offers adhesion-reducing properties to avoid the formation of BUE (built up edge) and increase tool life.

“The new cutters are designed to offer high-feed side milling with large axial depths of cut (ap) and low radial depths of cut (ae) along with a controlled maximum chip thickness so that the cutting forces are managed and provide a smooth cutting action,” explains Tiziana Pro, Global Product Manager Solid End Mills at Sandvik Coromant. “The result is twofold: increased productivity provides higher output, while greater tool life and reliability reduce scrap rates in what are typically high-value components. Additional customer benefits include reduced tool cost per component and greater safety levels.”

Target aerospace components include titanium wings and pylon parts, as well as engine cases made from Inconel 718. Applications in sectors such as oil and gas, medical and automotive, where titanium and nickel-based alloys are becoming increasingly prevalent, will also benefit.

To highlight the potential gains of this offer, a customer trial was performed, involving an LPT (low-pressure turbine) case made from aged Waspaloy 420 nickel-based alloy. Using a horizontal machining center, axial depth of cut was increased, and radial depth of cut was reduced (high radial forces are known to create deflection issues). Comparing a 12 mm diameter CoroMill® Plura HFS end mill against a competitor cutter of the same size, metal removal rate increased substantially, leading to an impressive 198% increase in productivity. As a result of this success, the customer has committed to ordering the new cutters from October 1, 2017.

HOPEWELL, Va., Nov 6, 2017 – A new class of flame retardant PET polyester films from DuPont Teijin Films promises to help designers in the industrial, transportation, construction, electronics and label industries provide improved safety at low cost. The halogen-free, clear Melinex® FR2XX series of polyethylene terephthalate (PET) films combines the inherent polyester film properties with the VTM-0 flame rating certified by UL’s UL 94 flame classification testing.

“Traditional PET polyester films are well-known for their performance and reliability characteristics, and this new film type has combined those properties with the highly desired VTM-0 certification,” said Scott Gordon, business development manager, DuPont Teijin Films. “We have worked closely with key customers to develop a clear flame retardant film that meets the needs of several industry segments.”

Recent reports have predicted growth rates over 7 percent per year in flame retardant polymer usage, driven by more stringent fire safety requirements in the construction, automotive and other industries. Some commercial polymer film types offer inherent flame retardance, but often at a price point of up to 30 times higher than PET films. Meanwhile, most PET polyester films are known for their physical durability, chemical resistance and low water absorption, but with typical flame classification ratings at only the VTM-2 level. Consequently, PET polyester films have been used in a limited range of applications, or in some cases the PET polyester film’s flame retardance was achieved through the use of expensive specialty adhesives, or through halogen containing film additives which are no longer permitted in many industries.

The Melinex® FR220 film is the first clear halogen-free VTM-0 PET polyester film from DuPont Teijin Films. Typical applications include laminate structures for construction and transportation, battery labels, insulating materials for wire and cable, electronic office products, lighting and flexible printed circuitry.
