Title: Grease manufacture
Filed: 1958-02-27
Abstract: A method of making a grease comprises forming a soap (or mixture of soaps) in an oleaginous vehicle from a mixture of soap-forming material and said vehicle which mixture contains a minor quantity (preferably 0.25-20 wt. per cent and particularly 0.5-10 wt. per cent) of water (the soap being formed preferably below its solution temperature); atomizing the product at below its solution temperature (preferably below the initial transition temperature of the soap) and at a preferred shear rate corresponding to a shear rate of about 20,000-100,000 (particularly 25,000-75,000) reciprocal seconds as determined in a pintle valve nozzle, instantaneously contacting the resultant droplets directly with a surrounding atmosphere, thereby substantially dehydrating the product (preferably so that it contains less than 0.25% of water); more intensely atomizing the product, below its solution temperature (preferably below the initial transition temperature of the soap) and instantaneously contacting the dispersed droplets so formed with a substantially cooler surrounding atmosphere to effect heat exchange.  The vehicle may be partly added following the dehydration step and/or following atomization of the dehydrated product.  The preferred vehicle is mineral oil, but other vehicles may be used as follows: (1) in the saponification step, any heat-, saponification-and hydrolysis-resistant vehicles, such as polymerized olefins (e.g. polypropylene), silicones (e.g. polymethylsiloxane), fluorocarbons and perfluoroalkyl ethers; (2) after the initial atomization step, any of the latter substances as well as others such as dibasic acid esters (e.g. di-(2-ethylhexyl)-adipate, sebacate and dibutyl phthalate), esters of polyalcohols and monocarboxylic acids, [e.g. polyethylene glycol di-(2-ethylhexoate)], the polyalcohols themselves (e.g. polypropylene glycol), silicate esters, esters of phosphorus-containing acids, and amines.  Said vehicles are characterized by a viscosity greater than about 40 S.U.S./100 DEG F., preferably from about 60-6000 S.U.S./100 DEG  F.  Optional ingredients may be added at any one or more stages in the manufacture.  In specific examples, the ingredients [(e) and (f) being optional], were (a) palmitic, stearic and oleic acids or hydrogenated soya and castor oil acids; (b) lithium hydroxide monohydrate (and, possibly hydrated lime); (c) a mixture of mono- and diheptyl diphenylamines as oxidation inhibitor; (d) naphthenic mineral oil, viscosity 750 S.U.S./100 DEG  F. (and possibly one of 135 S.U.S./210 DEG  F.); (e) a "multipurpose inhibitor" containing 1 part of oil and 1 part naphthenic acid-diethylene triamine reaction product; (f) water.

Filed: 1948-03-05
Abstract: 653,648. Automatic guns. TRIGGS, W. W. (Aktiebolaget Bofors). March 5, 1948, No. 6887. [Class 92 (ii)] Relates to short recoil automatic guns of the kind in which latches on the breech block are actuated during recoil through a release member pivoted to the barrel, the breech being opened by direct action of the gun gases on the cartridge case. According to the invention, the release member is pivoted below the barrel and during recoil strikes a fixed abutment to entrain a sliding member having cam surfaces to release the latches and impart an initial rearward movement to the breech block which movement is completed by the action of the gun gases. In the form shown, the breech block 12 is unlocked, on recoil of the barrel 1 after firing, by a lever 8 turning on a pivot 9 on the barrel extension 7, the arm 52 of the lever engaging a fixed stop 53 and the forked arm 81 engaging a striker plate 37 to move it rearward with striker sleeve 16 against the action of a spring 39, thereby releasing, through inclines 48, the pivoted latches 46 on the breech block from engagement with abutments 51 on the barrel extension. Thereafter, the gun gases acting through the cartridge case exert a blow-back action on the breech block to move it to open position against the action of a return spring 26. On closing movement, the forward inclines 50 on the striker sleeve 16 move the latches into engagement with the abutments 51, and the striker plate 37 moves forward to fire the gun by firing pin 35. Specification 574,352 is referred to.
