EOS to Present Laser-Sintering Clinics at Lab Day

Electro Optical Systems (EOS) will present two clinics, entitled 'Producing Bridges, Copings, Implants and Models from CAD Data Via Laser-Sintering', at this year's Lab Day in Chicago. The clinics are approved for 1.5 scientific Certified Dental Technician (CDT) credits. They will be held in Hospitality Suite 930 on 26 February from 8:30 until 10:00 and again from 10:30 until noon.

The clinics will give dental technicians the opportunity to learn about direct metal laser sintering (DMLS) as a cost-saving, efficient alternative to traditional casting methods for copings, bridges and implants. They will also explore plastics laser sintering for modelling, among other things, post-processing restorations. EOS engineer Thomas Thiel, master dental technologist, will conduct the clinics; he has previously worked in commercial laboratories specialising in crowns and bridges, combined removable partial dentures, implants and ceramics.

In addition to biocompatible cobalt-chrome copings and bridges, EOS DMLS systems are used for titanium implants with controlled porous surfaces that promote osteointegration. These implants are currently CE certified in Europe and are undergoing the Food and Drug Administration (FDA) approval process in the US. An additive manufacturing technology, laser sintering uses computer-aided design (CAD) and other 3D digital data to build parts, layer by layer.

DMLS equipment can run unattended to produce about 450 individually designed bridges and crowns for porcelain-fused-to-metal (PFM) restorations in 24 hours. In contrast, with the traditional lost-wax casting process, a dental technician can only produce about 20. EOS will also showcase samples of dental products at its exhibit during Lab Day, which will be held at the Sheraton Chicago Hotel and Towers on 25-26 February.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
