Patent GB-673148-A (GB)
Title: Improvements in or relating to organo-silicon co-polymers
IPC: C08G77/60
Filed: 1950-04-04
Abstract: Organo-silicon polyesters are made by reacting one or more di-(carboxyphenyl) dimethylsilanes with one or more polyhydric alcohols from the group glycerol, ethylene glycol and bis-(hydroxymethyl) dimethylsilane.  The reaction proceeds with elimination of water at a temperature from 90-200 DEG  C. and is catalysed by strong acids.  The molar proportions used are 1 mol. of alcohol to between 3 and 0.26 mols. of the carboxyphenylsilane. Products with an excess of hydroxyl or carboxyl groups may be modified by reaction with carboxyl-, hydroxyl-or amino-containing compounds.  The products may be liquids, thermoplastic resins or infusible thermoset gels, depending upon the reactants, the proportions thereof, and the heat treatment.  In examples: di-(p-carboxyphenyl) dimethylsilane was reacted (1) with bis-(hydroxymethyl) dimethylsilane to give a viscous oil which polymerized to a tough thermoplastic solid on further heating, strongly adherent to glass; (2) with a mixture of bis-(hydroxymethyl) dimethylsilane and glycerol to give a thermoplastic resin; (3) with glycerol to give a soft solid which gave a hard tough thermoplastic resin on further heating; (4) with ethylene glycol to give a soft solid melting at 160 DEG  C. which gave a brittle thermoplastic resin on further heating. Specification 670,923 is referred to.

Abstract: 802,049. Electrode materials and processing. FERNSEH G. m. b. H. March 23, 1956 [March 23, 1955], No. 9197/56. Drawings to Specification. Class 39(1). A secondary electron emissive electrode consisting of a metal support coated with an emissive alloy is made by separately coating on to the support the more easily oxidizable component of the alloy, and then the less easily oxidizable component. Thus one component is protected by the other, and may be so stored until assembled within the discharge device, when the electrode is heated under vacuum to alloy the two components. For example, a layer of magnesium 0À5Á thick is evaporated on to a nickel base, and then covered with a further layer of silver 0À7Á thick. Other suitable alloys are copper-beryllium and gold-magnesium, the first-named being the more readily oxidizable component.
