Patent GB-771716-A (GB)
Title: Improvements in or relating to foamed polyester-polyisocyanate reaction products
IPC: C08G18/20
Filed: 1955-07-07
Abstract: Foamed products are obtained by heating a mixture of a polyester, a polyisocyanate, a catalyst generator for generating a catalyst for the polyester-polyisocyanate reaction and a water generator.  Water generators specified are inorganic salts containing water of crystallization, particularly carbonates, e.g. sodium carbonate decahydrate.  Catalyst generators specified are tertiary amine salts, particularly the hydrochlorides of N-methyl, N-ethyl and N-phenyl morpholine and a mixture of aniline and b ,b 1-dichlorodiethylether which generates N-phenyl morpholine by cyclisation and evolution of hydrogen chloride. With carbonates as water generators any evolved hydrogen chloride from the catalyst generator is neutralized while causing evolution of carbon dioxide which assists foam production. Linear polyesters may be used to produce elastic foams and branched polyesters for rigid foams.  The mixes before heating are relatively stable and may be kept for long periods at 60 DEG  F. without premature reaction.  A dispersing agent may be included. In examples foams are produced from typical mixes using an adipic acid-glycol polyester, of acid number 1.5 and hydroxyl number 60, 2.4 tolylene diisocyanate, sodium carbonate decahydrate, N-ethyl morpholine hydrochloride or a mixture of aniline and dichlorodiethyl ether and as dispersing agent a condensation product of ethylene oxide and stearic acid.  The mix is placed in a mould, which may be preheated, and heated to about 250 DEG  F. for 30 minutes to bring about reaction and foaming.

Abstract: 223,006. Whaley, W. B. S. Aug. 7, 1923. Regulating; valves.-The front ends of the cylinders are closed by a dished plate 10 and are used as pump chambers to supply air through spring-pressed valves 32 to a reservoir 34. The air À from the reservoir 34 is admitted to the cylinders in turn through a check valve 40 and a reciprocating piston valve 35 driven from some variable linkage gear such as a Stephenson link motion. After the air has been cut off, the compression pressure is limited by an equalizing-chamber 37; if the pressure rises excessively, part of the air is discharged through balanced non-return valves 53, Fig. 2, to the chamber. Liquid fuel is injected through the nozzle 25; during combustion, the valve 35 connects the cylinder to the equalizer chamber so as to balance and limit the pressure in the cylinder. During expansion, the valve cuts off the chamber from the cylinder.
