Patent GB-705325-A (GB)
Title: Lubricating grease compositions
IPC: C10M169/00
Filed: 1951-10-25
Abstract: A lubricating grease comprises lubricating oil thickened with the aluminium soap of a mixture of acids consisting of 87-93 per cent. by weight of a soap-forming fatty acid and 7-13 per cent. of a non-aromatic alicyclic dicarboxylic acid having a molecular weight of 300-700.  The lubricating oil may be mineral lubricating oil or a synthetic lubricant such as oxyalkylene polymers (e.g. propylene oxide polymers, ethylene oxide-propylene oxide copolymers, trimethylene glycol polymers and ethylene glycol-trimethylene glycol copolymers), silicone fluids, organic phosphates (e.g. tricresyl, trioctyl, diphenylcresyl or diphenyloctyl phosphate), polymerized olefins, polyvinyl caprylate, and esters of dicarboxylic acids (e.g. di(2-ethylhexyl) sebacate and di(3-methylheptyl) adipate). Soap-forming fatty acids mentioned are the saturated and unsaturated fatty acids and the substituted fatty acids such as ricinoleic, licanic and 12-hydroxystearic acids.  Such fatty acids may be derived from animal, fish and vegetable fats and oils or the corresponding hydrogenated oils.  The non-aromatic alicyclic dicarboxylic acids may be monocyclic or polycyclic and may be prepared by the dimerisation of unsaturated soap-forming fatty acids.  The mixed aluminium soaps may be formed in the presence of lubricating oil, for example by saponifying the mixed acids with aluminium hydroxide in presence of lubricating oil.  Alternatively the mixed soaps may be first prepared and then added to the lubricating oil. The lubricating grease may contain other ingredients such as inorganic colloidal gelling agents (e.g. silica, alumina, magnesia, lime, magnesium silicate, aluminium silicate, bariumoxide, copper sulphide, bentonite, hectorite and synthetic clay-like materials), film-forming anticorrosion agents (e.g. sodium dichromate or sodium nitrite), cationic surface-active agents (e.g. amines, amides and quaternary ammonium compounds, particularly octadecylamine, the partial oleic acid amide of tetraethylene pentamine and dimethyl diheptadecyl ammonium chloride) and antioxidants (e.g. phenyl-alphanaphthylamine and alkylated cresols).  In the examples, greases are described consisting of mineral lubricating oil and the mixed aluminium soaps of (a) hydrogenated fish oil fatty acids and dimerized linolenic acid or (b) 12-hydroxy stearic acid and 1, 3-di(6-carboxyhexyl) 4, 5-diheptylcyclohexane.

The shell e is turned over at the top to leave an opening of less diameter than the refractory core a'and is welded to arms h extending from a wire ring j fitting in the axial recess in the top of the core a. The lower end of the substantially cylindrical core a is slightly tapered and provided with an axial recess into which is cemented a 'spigot b cemented into a control recess in the refractory top c of the circular burner d. A sheet metal baffle v spaced from the skirt l serves to protect the front of the fire, and the floor on which it stands, from damage. The burner d is a hollow annular casting open at its top to receive a steatite top c pierced with burner holes. The burner is supplied with non- aerated gas from a pipe t, and the assembly is primarily intended for use in portable gas fires of the reflector type. The inturned upper edge of the metal shell may engage a shoulder formed on the refractory core.
