Title: Improvements in or relating to organosilicon resins
IPC: C09D167/00
Filed: 1960-02-05
Abstract: A coating resin is made by heat reacting an alkyd or oil-modified alkyd resin or the components thereof with a siloxane resin containing Si-bonded OH and/or OR radicals containing less than 6 C atoms, in the presence of a monomeric or polymeric titanate or zirconate in which the organic radicals attached to metal through oxygen atoms are hydrocarbon or acyl radicals.  Many alkyd resin-forming reactants are specified. Specified silicon-bonded organic radicals are alkyl, cycloalkyl, alkenyl, aryl, alkaryl and aralkyl, and the titanates and zirconates may contain the same radicals, except cycloalkyl, but attached to metal through oxygen. The reaction may be effected in a solvent, e.g. alcohols, hydrocarbons, esters, ketones and chlorohydrocarbons.  In a typical Example (1) a b -ethoxyethylacetate solution of an alkyd resin (obtained from isophthalic acid and trimethylolpropane), was mixed with butyl acetate, a copolymer of monophenyl- and mono-propyl-siloxane units and containing Si-bonded hydroxyl and isopropoxy radicals, and butyl titanate and heated at 135-140 DEG  C. until homogeneity was attained.

Filed: 1937-02-12
Abstract: 480,994. Valve amplifying circuits. GENERAL ELECTRIC CO., Ltd., and MACFADYEN, K. A. Feb. 12, 1937, No. 4256.. [Class 40 (v)] In a quiescent push-pull amplifier constant automatic bias is maintained by connecting one plate of a condenser 18 directly to the cathode end of the biassing resistance 10, and the other plate to the other end of said resistance through a rectifier 16 opposing the flow of current in such a sense as to make the grid negative to the cathode. When the cathodes are not directly connected together, the biassing resistance 10 and its associated condenser 18 are duplicated, each supplying bias for its own grid circuit. A single rectifier may serve for both biassing circuits, or this also may be duplicated. The rectifier 16 may be of the dry-plate type, and the product of its reverse resistance and the capacity of the condenser 18 may be two seconds. To prevent the valves operating without bias when first switched on, the main switch may be ganged with a switch for shorting the rectifier 16 for a few seconds.

[Class 110 (ii).] A rotary compresser or motor has outwardlysliding vanes which are placed obliquely to the axis of the stator, the angle of obliquity being a few degrees only. For a compresser the leading edge of a vane 4, Fig. 2, is located at the end of the working chamber remote from the delivery port 7 so that compressed fluid has an axial thrust given towards the port 7. The inlet port 5 may be in the middle of the working chamber as in Fig. 2. In a modification the vanes may be arranged axially in the rotor and the rotor set obliquely in the cylinder. In this case the rotor would be of a parabolic contour. Fig. 5 shows an alternative arrangement in which the apices of sloping vanes 4 lie in the plane of the inlet port 5 and two delivery ports 7 are situated in the end walls of the stator. The vanes, in another compresser, have their apices lagging, and deliver fluid through a central port 7. The compresser illustrated in Fig. 2 may be made reversible by having alternate inlet ports at each end of the stator. The difference in size between the rotor diameter and the stator bore may be about one-sixth of the rotor diameter. To force the vanes outwards springs or compressed fluid may be used.
