Polyurethane tubing

A line of ether-based polyurethane tubing that is clear, flexible, tough and better suited for vacuum and pressure applications than PVC or rubber is being introduced by the company. Featuring 85 Shore A hardness, 5,500 psi tensile strength, and 580% elongation at break, the tubing is available in a wide variety of sizes and wall thickness from 1/16 to 2 inch ID. Containing no plasticizer that can cause flow contamination or tube hardening, it is offered in both ether-based and ester-based formulations and is priced according to size and quantity.

Lubricant detection

The Hydrolert automatic moisture monitor reportedly detects water in lubricating oils before damaging levels are reached, and as a result, extends equipment life and decreases maintenance and downtime costs. According to the company, unlike conventional oil monitoring which measures moisture in parts per million, the product continuously monitors saturated relative humidity (SRH) and warns if the lubricant reaches 70 percent SRH, a point before free water occurs and damage can begin.

Speech recognition

Speech(TM)6.0 offers new word spotting and high-speed speech framing algorithms. The word spotting function allows machines such as cell phones, answering machines, and alarm clocks to recognize phrases, even if they're uttered in the middle of sentences. It includes a development tool to allow programmers to convert 22 Khz, 16-bit .wav files into compressed formats that can run on the company's RSC-300/364 speech processors.

Cement

Tempseal Cement No. 3 is said to be highly resistant to both high temperatures and moisture, properties which its manufacturer says were long thought to be mutually exclusive. The product contains a lithium silicate binder hybrid and proprietary fillers, and has a reported heat tolerance of up to 3000 F. The cement is available with a variety of thermal expansion coefficients for bonding to ceramics, metal, and glass.

Elastomeric bearings

Load-carrying elastomeric bearings are designed to absorb, dampen, and control large forces, such as those occurring in aerospace and rail car applications. The bearings are constructed of layers of special elastomers alternating with disks made of steel, aluminum, titanium, or composites. The company says this reduces what had been a multi-component assembly into a single unit which requires no lubrication.

Thermoplastic valve

The company has developed a high-flow capacity 3 inch NPT Relief Valve for corrosive and ultra-pure liquids. The product is an angle-pattern valve constructed of high grade PVC with a choice of Viton or EPDM elastomeric seals. The sensing element is a PVC shaft with a Teflon thrust washer to reduce friction working in conjunction with a large area-rolling diaphragm. This feature enables the valve to open more rapidly providing greater flow and sensitivity to changing pressure.
