get 'em while they're hot
Linear potenti- ometers Omega Engineering, Stamford, Conn.	The LP801 series has been designed to measure linear position or displacement up to 48 in. The potentiometers feature front and rear bearings, anodized extruded aluminum housing, stainless-steel shaft, and precious-metal wipers and contacts. They provide high-resolution, absolute position measurement without external signal conditioners.
High- temperature couplings Ringfeder Corp., Westwood, N.J.	High-temperature Arcusaflex couplings operating with elastomeric silicone-rubber elements are said to be extremely well suited for high-temperature applications. In the range of 70°C to 180°C there are no changes in material characteristics during long-time operation. Torque transmission range is from 150 Nm to 40,000 Nm. Different designs with sae-flange connection measurements (sae 6.5-24 in.) are available.
Industrial vortex system George Fischer Inc., Tustin, Calif.	The new +GF+ Signet industrial vortex system has an injection-molded sensor and transmitter system that uses vortex technology to provide a versatile and cost-effective way to measure and transmit flow rates. Each system features state-of-the-art true union with socket fusion, butt fusion, or solvent cement socket connection options for application versatility. PVC, PP, or PVDF material options provide exceptional chemical compatibility. The transmitter provides an adjustable 4-20 mA signal and an open-collector sensor pulse output signal.
Vacuum- assisted still Westport Environmental Systems, Westport, Mass.	Vacuum-assisted Solvo-Salvager distillation systems allow in-plant purification and reuse of up to 98 percent of contaminated solvents. Systems are designed to process safely and efficiently a wide range of both flammable and nonflammable solvents with boiling points up to 500°F; they are available with capacities to 55 gallons per 8-hour shift. After a unit has been shut down and allowed to cool, sludge can be drained by opening a valve at the base of the system.
Switch caps C&K Components Inc., Watertown, Mass.	A number of caps are now available to fit the pn Series alternate-action pushbutton switches. The caps are molded of abs thermoplastic and are offered in a variety of colors including white, black, and red, with round, square, and rectangular shapes.
Temperature sensor Vespo Marketing Associates Inc., Thompson Ridge, N.Y.	The Series M50 infrared temperature sensor measures moving or hard-to-sense targets and has a wide range of outputs that can be specified to simulate a Type J or Type K thermocouple, 5 V dc or mV per °F or °C. Accuracy is 1.5 percent, repeat-ability is 0.25 percent, and resolution is 0.1 percent. Temperature range is -20°C to +300°C.
Hydraulic intensifier Power Team, Owatonna, Minn.	A new hydraulic intensifier converts low-pressure hydraulic pumps into high-pressure power sources. It can boost a pump from a 2000 psi/140 bar unit into a 10,000 psi/700 bar power source. The intensifier weighs just 7.3 kg and delivers a pressure ratio of 5:1. It operates single- or double-acting cylinders and tools such as jacks, crimpers, cable cutters, nut splitters, tire tools, and similar hydraulic-actuated devices.
Gasket materials Thermoseal Inc., Sidney, Ohio.	A wide range of Klingersil compressed, flexible graphite and ptfe gasket materials is now available from Klinger's North American licensee. They include metal- and wire-reinforced products and a wide variety of sheets for best general purpose and steam- and corrosion-resistant services. Other Klingersil materials provide superior to excellent load-bearing and creep-resistant properties.
Time delay relays SSAC Inc., Baldwinsville, N.Y.	The trdu Series of plug-in, switch-adjustable, multimode time delay relays is designed to simplify the selection of a plug-in time delay relay. One trdu replaces hundreds of conventional time delay relays. Industry-standard 8- and 11-pin base wiring makes substitution simple and fast with no rewiring required. The new series features 21 operating modes. Any one of the 10 single-function or 11 dual-function modes is selected by transferring one or more of the six programming switches. Time delays are available from 0.1 sec to over 1705 hr in eight ranges. Timing accuracy is ±0.1% and setting accuracy is ±1% over the full adjustment range.
Steam traps Nicholson Steam Trap, Walden, N.Y.	New ftn float and thermostatic steam traps are said to be excellent for use in systems where condensate and air need to be removed from the steam system quickly and continuously. The iron body traps have stainless steel internal parts for long life. They offer a universal four-port design, allowing four hookup combinations. Typical applications include unit and space heater applications, heat exchangers, reboilers, air heating coils, main steam drips, and process equipment.
