Inventor: KINKELAAR MARK R
IPC: C08G18/63
Filed: 1996-03-11
Abstract: High  resilience  polyurethane  foams  having improved wet set properties are obtained by reacting an isocyanate with a polyol  component  consisting of  a polyoxyalkylene polyol with a functionality of 6 or more and a polymer polyol whose base polyol is a polyoxy-alkylene polyol with a functionality of 6 or more, both polyols having oxyethylene caps in amounts of from 12 percent to about 30 percent based on the weights of the respective polyols, in the presence of an amine catalyst system.  The resulting polyurethane foams are eminently suitable  for  seating  cushions  used  in  tropical  or subtropical environments,  may be prepared by a cold molding process, and may be used without an elevated temperature post cure.

IPC: E21B34/10
Filed: 1996-09-23
Abstract: A downhole valve 10 opens or closes a bypass (12,13) in response to the pressure of the fluid in the valve. The valve housing body 14 is adapted for fluid communication with a tubular within a well bore. The valve bypass may be repeatedly cycled from open to closed position by selectively raising and lowering the fluid pressure. A replaceable flow restriction 18 in the valve is sized to produce a desired flow-induced pressure drop across the valve to cycle the valve with fluid flow. Differential sealing areas (11c and 15,16) are provided to cycle the valve by varying the static fluid pressure in the valve. According to the method, a flowing fluid pressure drop induced by fluid flow through the valve isused to change the state of the valve, and a subsequent change in hydrostatic fluid pressure or fluid pressure is used to return the valve to its original state.

Title: Merging the functions of switching and cross connect in telecommunications networks
Inventor: ANDERSON THOMAS WAYNE
IPC: H04L12/56
Filed: 1997-01-20
Abstract: Apparatus and a method for establishing voice band telecommunications connections using a cross connect/switching system (CCSS) for establishing all or part of the connection setments required for individual calls.  The CCSS contains bundles of provisioned paths and also has facilities for establishing individual per call paths which do not use these bundles.  When a call is received, the CCSS switches the call through a combination of provisioned and unprovisioned paths.  In the preferred embodiment, the CCSS is an asynchronous transfer mode (ATM) switch enhanced with converters to communicate with pulse code modulation (PCM) facilities for communicating with other switches and with associated PCM switches. Terminal adapters are provided in either the CCSS or the associated switches or both for processing voice signals to perform functions such as echo cancellation or speech quality enhancement.  Advantageously, such a switch can support a very large node that carries extensive wideband and broadband signal traffic as well as the voice band traffic.

Title: Gas monitors
Inventor: PARRY MICHAEL
IPC: G01N21/03
Filed: 1997-08-06
Abstract: A gas monitor includes an infra-red source 5 enclosed within a housing 2 having inner surfaces which are reflective. Radiation emitted from the source 5 reflects off ellipsoidal surfaces 7 and 8 and intermediate planar surfaces 3 and 9 to be focussed at a sensor 6, being reflected five times. Radiation is absorbed by gas within the housing and a comparison of the source intensity and detected intensity gives a measure of the gas concentration. Use of ellipsoidal reflective surfaces 7 and 8 directs emitted radiation along a plurality of routes having substantially the same path length, hence giving an accurate measure of the gas concentration with a compact device. In another embodiment, off axis parabolas are used to direct the radiation through the gas.
