Title: Lubricating composition
Inventor: MATUSZAK ALFRED HENRY
IPC: C07F7/02
Filed: 1962-06-05
Abstract: An organosilicon compound for use as a lubricant per se or as a minor constituent of a synthetic ester lubricating composition (see Division C5) is made by reacting a silane of the formula R3SiX, in which X is OH or halogen and R is X or a C1 to C15 hydrocarbon radical, with a synthetic ester consisting of a saturated hydrocarbon or oxo-hydrocarbon radicals interlinked by two or more ester linkages and containing a total of 20 to 60 C atoms per molecule. The reaction is effected either by heating a mixture of the reactants for 1 to 16 hrs. at 40 DEG  to 165 DEG C. or by subjecting the mixture to high energy radiation.  In examples (1) (CH3)2SiCl2 and (2) SiCl4 were each reacted with a mixture of di(C8oxo) adipate and di(C10oxo) adipate.ALSO:A lubricating oil composition comprises a major proportion of a synthetic ester and a minor proportion of a substantially neutral reaction product of a synthetic ester and a silicon compound, wherein each of the esters consists of saturated hydrocarbon or oxo-hydrocarbon radicals interlinked by two or more ester linkages and contains a total of 20 to 60 C atoms per molecule, and the silicon compound has the formula R3SiX, in which X is OH or halogen and R is X or a C1 to C15 hydrocarbon radical. The ester oils used are the diesters of aliphatic dicarboxylic acids with alcohols and the complex esters obtained by reactrons between a dicarboxylic acid, a glycol and an alkanol or a monocarboxylic acid.  The composition preferably contains 0.5 to 10% by weight of the reactron product, and may also contain minor amounts of additives such as other types of oils, detergents (e.g. calcium petroleum sulphonate), oxidation inhibitors (e.g. phenylalphanaphthylamine), viscosity index improvers (e.g. polyisobutylene),) corrosion inhibitors (e.g. sorbitan mono-oleate0), pour point depressants, dyes and C6-C10 dicarboxylic acids.  In Examples (1) (CH3)2SiCl2 and (2) SiCl4 were each reacted with a mixture of di(C8oxo) adipate and di(C10oxo) adipate, and the products were separately added to synthetic ester oil compositions.  The reaction products per se are also useful as lubricants.

Abstract: 843,803. Making moulds by electro-forming. LYTLE, J. K. July 8, 1958, No. 21878/58. Class 41. In a process for making moulds and dies by electro-forming, the pattern is electro-plated e.g. with copper, the copper shell is stripped off and again plated on the pattern face to form a second shell which is separated by stripping and is mounted in a metal casting framework, and again plated to rigidly connect the third shell thus formed to the framework. The second shell is then removed and the under-side of the third shell and frame is filled e.g. with metal, to reinforce the shell and thus form the final mould. Before each electro deposition the pattern or shell is thinly coated with wax and then bronze powder, graphite, or silver nitrate solution to render the surface conductive. Preferably the 1st and 2nd shells are of copper of 0À015 to 0À063 ins. thick, and the final shell of nickel 0À045 ins. thick. A number of such master moulds may be prepared. A suitable plating apparatus comprises a tank holding electrolyte 69 which is circulated by a pump 77 from a sump 78 to a manifold nozzle 80 electrolyte overflows through a filter 81 to the sump. The pattern to be plated 30 is contained in a wax-impregnated wooden basket 82, above which and resting in a muslin cloth 85, is a sheet copper anode 88 on which pieces of copper are placed e.g. finely divided scrap or shot, to increase the anode surface.
