Title: Process for the production of mouldings
IPC: C08G18/02
Filed: 1976-07-29
Abstract: 1487541 Polymers containing isocyanurate groups BAYER AG 29 July 1976 [31 July 1975] 31632/76 Heading C3R A process for the production of a moulding comprises polymerizing at least one organic polyisocyanate in a closed mould in the presence of a compound which catalyses the trimerization of isocyanate groups and in the absence of blowing agents. The process may be carried out in the presence of an organic compound which contains isocyanate reactive groups, the equivalent ratio between isocyanate groups and isocyanate reactive groups being greater than 1 : 0À8. The catalysts used in this process are conventional trimerization catalysts such as sodium or potassium phenolate, lead naphthenate, alkaline earth and alkali metal oxides, and a mixture of o- and p-dimethyl amino methyl phenol which may be used in amounts of from 0À1 to 10% by weight based on the polyisocyanate component. In a typical example a polyether triol Mol. Wt. 300, a polyether triol Mol. Wt. 4600, a silicone stabilizer, sodium acetate as trimerization catalyst, dimethylbenzylamine and a polyisocyanate containing urethane groups obtained by modifying a phosgenation product of an aniline formaldehyde condensate containing 79% by weight, of diisocyanato diphenyl methane with 3% by weight of tripropylene glycol are polymerized in a closed mould at 65‹ C. Mouldings obtained by this process may contain reinforcing elements, e.g. three dimensional structures of metal, plastics or plywood through which the reaction mixture is able to flow during the moulding process.

Abstract: 1,003,221. Engine stop gear. ENGLISH ELECTRIC CO. Ltd. Dec. 21, 1961 [Sept. 21, 1960], No. 32400/60. Heading F1K. A hydraulic governor head wherein the internal hydraulic pressure increases with increasing speed, is provided with a trip lever or trip switch at the end of the governor stroke corresponding to low speed which causes the power supplied by the prime mover to be reduced upon loss of hydraulic pressure. Alternatively the internal hydraulic pressure diminishes with increasing speed, whereby loss of hydraulic pressure simulates an overspeed condition and causes the supply of energy or fuel to the prime mover governed to be shut off. As shown a release lever 26 is arranged at an axial distance from the upper end face of the flange 25. If the hydraulic pressure is lost the spring 8 moves the cup body 22 upward until its flange 25 touches and moves upwardly the lever 26 thus reducing the power output of the prime mover. In a modification the output of the prime mover is reduced by operation of a switch electrically connected to a control member. In an alternative construction the outward movement of the governor weights involves a reduction of the hydraulic pressure produced by the preloading of springs.
