Title: Improved polyether compositions
Inventor: AITKEN ROXBURGH RICHMOND
IPC: C08K5/13
Filed: 1961-02-01
Abstract: Didodecyl thiopropionate is prepared by reacting hydrogen sulphide with ethyl acrylate in the presence of sodium methoxide to form diethyl thiopropionate and trans-esterifying with dodecanol.  The dioctadecyl ester is similarly prepared.ALSO:Polyethers are stabilized by a mixture of a phenol and a diester of a sulphur-containing dicarboxylic ester of the general formula R1OOC.R3.S.R4.COOR2, wherein R1 and R2 may be the same or different and are straight or branched chain alkyl, aryl, aralkyl or cycloalkyl groups), or alkyl groups in which the chain is interrupted by oxygen or sulphur atoms, and R3 and R4 may be the same or different and are straight or branched chain alkylene, arylene, arylene alkylene, arylene alkylene arylene or alkylene arylene alkylene groups. Specified diesters are didodecyl thiodipropionate, dioctadecyl thiodipropionate, di-2-ethylhexyl thiodibutyrate, diethyl thiodipropionate, benzylethyl thiodiproprionate, diethyl thiodipropionate acetate, didodecyl thiodiacetate, and bis-2-methoxyethyl- and bis-2-methylthioethyl - thiodiproprionate. Specified phenols are dihydroxy diphenyl alkanes, dihydroxydiphenyls, alkylated hydroxybenzenes, alkylated dihydroxybenzenes, alkylated polyhydroxypolyphenyl alkanes or alkyl benzenes. The polyethers, which may be linear or branched, are condensates of alkylene oxides alone or with compounds containing active hydrogen, diepoxides, glycidols or 3-hydroxymethyloxycyclobutanes. The proportion of ester and phenol may each be 0.05-10% by weight of the polyether.  The ester-phenol proportion is generally 70:30 to 30:70 by weight. The stabilized polyethers may be reacted with polyisocyanates to form rigid or flexible, homogeneous or cellular polyurethanes. In the examples:  (1) polypropylene glycol (mol. wt. 2100) is stabilized with didodecyl thiodipropionate and 2-(2-methylcyclohexyl)-4,6-dimethylphenol and the solution reacted with a mixture of 2,4- and 2,6-tolylene diisocyanate; (2) the phenol of (1) is replaced by the condensation product of crotonaldehyde and 3-methyl-6-tert.-butylphenol.  Many more combinations of stabilizers are given in Example 3.

Abstract: A method of reducing the nitrogen content of iron or ferrous alloy articles comprises coating the article with a layer of a nitrogen-accepting metal and annealing the article under such conditions that some or all of the nitrogen enters, and is retained by, the coating but prevents diffusion of the coating metal into the article.  The coating layer may be removed after cooling.  The coating metal may be Al, Cr, Ta, Ti, or V and may be applied electrolytically or by vapour deposition to a thickness depending on the thickness of the article and the desired reduction in nitrogen content.  The annealing may comprise heating to 400 DEG C. to 800 DEG C. for two hours followed by cooling at a rate less than 100 DEG C. per hour.  The coating metal may be applied prior to any mechanical working before annealing.  Curves are given for Al coated on iron and show the relationship between the nitrogen content of the base and the thickness of coating on each side, and between the annealing time and the temperature.

Title: Data processing system
IPC: G06F9/38
Filed: 1978-02-02
Abstract: One editing processor and one executive processor (EP) each are provided which are jointly controlled from a loadable microprogram memory (WCM), the first processor remaining autonomous due to a separate detail control (ZS-ROM). Thus, both processors can jointly use one interface to the memory system (ASP) and one set of internal general registers (MA, MD) without mutually impeding each other. Since the editing processor only provides register operands or effective memory addresses of a subsequent machine instruction, register or memory conflicts can be solved in a simple manner with the aid of comparison devices (SV1, SV2 and RV1, RV2) for memory and register addresses. The editing processor takes over the reading of instructions and the calculation of addresses and the executive processor takes over the execution of instructions. A configuration of the type described is considered particularly in medium-capacity commercial data processing systems. <IMAGE>
