Title: Improvements in engine starter drives
IPC: F02N99/00
Filed: 1937-12-07
Abstract: 507,015. Turning -gear. ECLIPSE MACHINE CO. Dec. 7, 1937, No. 33910. Convention date, Dec. 9,1936. [Class 7 (v)] In an engine starter drive comprising a pinion 11, slidably journalled on a power shaft 1 for movement into and out of mesh with an engine member 12, and a nut 7 having a threaded connection with the shaft 1, rotation and longitudinal .movement are transmitted from the nut to the pinion by means of a barrel member 13 and a cam connection between the barrel member and the pinion and operative to turn the pinion with respect to the barrel when the meshing movement of the pinion is interrupted. As shown, the nut 7 is threaded on a screwed sleeve 4, freely journalled on a sleeve 2 fixed on the shaft 1 and driven from the sleeve 2 through a torsion spring 5 having flattened convolutions. The barrel 13 is splined on the nut 7 and is connected to the pinion through cam members 15, 16 normally held in extended relation by a spring 26, the member 16 being fixed on the pinion and the member 15 splined in the barrel. Lock rings 19, 21 retain the members 16, 7 in the barrel and the movement of the nut 7 is limited by a thrust ring 8 and a stop on the sleeve 2. When the sleeve 4 is driven from the shaft 1, the axial movement of the nut is transmitted to the members 15, 16 and the pinion by thrust bars 23 fixed on the nut and engaging splines in the barrel. When the pinion meshes with the engine member 12 and a thrust ring 22 in the barrel abuts against the thrust ring 8, longitudinal movement of the barrel is stopped ; further longitudinal movement of the nut causes the cam member 15 to be forced into full engagement with the member 16 until the nut 7 engages the thrust ring 8, and the sleeve 4 then moves back against a thrust washer 29, compressing the drive spring, so that the parts are clamped together for rotation in unison. If the teeth of the pinion clash with those of the member 12, the continued advance of the nut 7 forces forward the cam member 15 and turns the member 16 and the pinion into meshing position by means of cam faces 24, 25 on the members 15, 16. The screwed sleeve 4 has a smooth portion adjacent to the idle position of the nut 7, to allow dissipation of the momentum of the nut when it runs off the screw threads, and a spring 28 ensures reengagement of the nut-with the threads.

Abstract: 999,609. Insulators. A. REYROLLE & CO. Ltd. Sept. 5, 1962 [June 5, 1961], No. 34101/62. Divided out of 999,608. Heading H2C. A method of manufacturing a high-voltage insulating bushing having conducting inserts embedded in its wall comprises passing a continuous web of insulating material 30, such as paper, through a fluidized bed of synthetic resin powder 37, to cause a layer of resin to be deposited on one side of the web, winding the coated web under heat and/or pressure into the form of a bushing 47 on a conductor 45 or other support, and continuously or intermittently inserting metal foil 46, or other conducting material, between adjacent turns during winding. Preferably an epoxy resin or high density polythene is used as the coating material and this is maintained in the fluidized state by air or inert gas passed upwards through the perforated bottom 39 of the container 33. An electrically heated block 34 around which the web 30 is passed is narrower than the web itself and thus the margins of the web do not become coated, thereby avoiding the pressing out of excess resin during the winding stage. When fully wound, the bushing is heated in an oven to cure the resin. Specification 759,214 also is referred to.

Title: Grease composition
Filed: 1955-12-02
Abstract: Water-resistant lubricating greases, suitable for use over a wide temperature range, comprise a lubricating oil thickened with the calcium salts of a mixture of (I) 10-60 per cent of a straight chain alkane monocarboxylic acid containing 1-6 carbon atoms per molecule; (II) 10-80 per cent of an alkane monocarboxylic acid containing 7-12 carbon atoms per molecule and having no side chain larger than a methyl group; and (III) 2-75 per cent of a fatty acid containing more than 12 carbon atoms per molecule and containing at most one olefinic carbon-to-carbon double bond and at most one hydroxyl substitutent per molecule, all percentages being by weight.  The lubricating oil may be mineral oil, an ester of an aliphatic or aromatic dicarboxylic acid such as di-(2-ethylhexyl)-sebacate or adipate or dibutyl phthalate, a silicone, a silicate ester, an ester of a phosphorus-containing acid, a fluorocarbon, or an ester of a polyalcohol with a monocarboxylic acid such as polyethyleneglycol di-(2-ethyl hexoate).  Acid I may be acetic, propionic, butyric, valeric or caproic acid.  Acid II may be heptanoic, caprylic, pelargonic, capric undecylenic or lauric acid of the mixed unsubstituted C-.  C1- and C12 acids having methyl side chains obtained by the oxo process.  Acid III may be myristic, palmitic, stearic, arachidic, behemic, lignoceric, cerotic, oleic or 9-(or 10- or 12-) hydroxystearic acid, or branched chain isomers of such acids, or mixtures of such acids. The lubricating grease may contain additional ingredients such as antioxidants (particularly amines such as phenyl alpha-naphthylamine and phenols such as 2,6-di-tert. butyl-4-methylphenol) and lubricity improving agents (particularly free fats, free fatty acids, esters of aliphatic and/or aromatic monocarboxylic acids, sulphurized fats and lead soaps), while anti-foam agents such as silicones may also be added during the preparation of the grease.  In the preparation of the grease, the acids may be reacted, in the presence of the lubricating oil, with insufficient lime to complete neutralization of the acids, the mixture dehydrated and then further lime added so that the acidity is at least completely neutralized.  The lime employed may be calcium oxide or hydroxide or, alternatively, calcium carbonate may be used. In the examples, greases are prepared from mineral lubricating oil, lime, acetic acid, caprylic or pelargoic acid and stearic or oleic acid.  For comparison purposes, the preparation of greases from sodium, lithium or barium salts of mixed acids, and also from calcium salts of mixtures of acetic acid with only high molecular weight fatty acids, is described.
