Title: Extreme pressure lubricant compositions and the like
IPC: F01M7/00
Filed: 1955-01-18
Abstract: An extreme pressure lubricant comprises a lubricating oil from 3 to 10 per cent by weight of a phosphosulphurized hydrocarbon and a halogen- and sulphur-containing hydrocarbon, the phosphosulphurized hydrocarbon being present in a greater proportion than the halogen- and sulphur-containing hydrocarbon. The phosphosulphurized hydrocarbon may be prepared by reacting P2S3, P2S5, P4S3 or P4S7 with paraffins, olefins, olefin polymers, diolifins, acetylenes, aromatics or alkyl aromatics, cyclic aliphatics, petroleum fractions such as lubricating oil fractions, petroleums, waxes, cracked cycle stocks, condensation products of petroleum fractions and solvent extracts of petroleum fractions.  Specified monoolefins are isobutylene, decene, dodecene, cetene octadecene, cerotene, melene, gasoline, olefinic extracts from gasoline, cracked waxes, dehydrohalogenated chlorinated waxes; polymers of monolefins may also be used.  In addition, aromatic hydrocarbonic such as benzene, naphthalene, anthracene, toluene, xylene, diphenyl, and alkyl substituted aromatics, or resin-like oils of high molecular weight may be used.  The reaction product may be obtained by heating the phosphorus sulphide with the hydrocarbon to a temperature of 300-550 DEG F. in a non-oxidizing temperature such as an atmosphere of nitrogen.  The product may be refined by blowing with steam, alcohols or phenols at a temperature of 200-600 DEG F.  The sulphur- and halogen-containing organic compound may be a halo-hydrocarbon sulphide such as a mono-or di- or polysulphide. Aromatic derivatives such as the chlorinated and brominated alkaryl sulphides are preferred, although sulphochlorinated hydrocarbons such as those formed by treating olefins, paraffins, and naphthalenes with sulphur halides may be used.  Specified compounds are chloroparaffin wax polysulphide, dibromodiphenyl disulphide, dichlorodibenzyl sulphide, and chlorodimethylbenzyl disulphide.  The oil may be a mineral oil, which may have been refined, with acid, alkali or solvent extraction treatment, or an animal, vegetable or fish oil, which may be hydrogenated; or a synthetic oil of the ester, polyester or polyether such as di - 2 - ethyl - hexyl sebacate, dibasic acid esters and polyalkyllene oxides.  Stability may be increased by adding a soluble metal petroleum sulphonate such as that of lithium, sodium, potassium, calcium, strontium, or barium; and a metal alkyl phenol sulphide which may be that of calcium, barium, strontium or magnesium.  The preferred proportions are 3-20 per cent of phosphosulphurized hydrocarbon, 0.1 to 10 per cent of the sulphur and halogen containing organic compound, and 0.02 to 1 per cent of the metal petroleum sulphonate.

Abstract: 944,112. Cathode-ray storage tubes. ENGLISH ELECTRIC VALVE CO. Ltd. Sept. 7, 1961 [Jan. 13, 1961], No. 1522/61. Heading H1D. In a direct-viewing storage tube, different successively recurrent potentials P.S. are applied between the storage grid backing SM and the flood gun cathode FC, so that input signals SS above a predetermined strength, applied to modulate the writing beam, result in stored charges which permit flood beam electrons to pass through the storage grid at full strength, whereas input signals below said predetermined strength result in stored charges which substantially cut off the flood beam electrons. Preferably the recurrent potentials comprise two timespaced rectangular pulses occurring for equal time periods, the larger one alone producing a secondary emission ratio, in relation to flood beam electrons, which is as much above unity as the corresponding secondary emission ratio produced by the smaller one alone is below unity. Alternatively, the pulses need not be of equal duration, provided that their amplitudes are such that, in the absence of a " writing " signal, the amount of positive charge acquired by the storage insulator during the larger pulse equals that lost during the shorter pulse. Also, the pulses need not be time-spaced. Stored signals can be erased by omitting the larger amplitude pulses.
