Patent number: 11697783Abstract: The present invention provides a non-aqueous lubricant composition comprising a base stock and 5 at least 0.02 wt % of a friction reducing additive which comprises a block co-polymer of at least one block A which is an oligo- or polyester residue of a hydroxycarboxylic acid and at least one block B which is a residue of a polyalkylene glycol. The invention also provides the use of a block co-polymer of at least one block A which is an oligo- or polyester residue of a hydroxycarboxylic acid and at least one block B which is a residue of a polyalkylene glycol to reduce the kinetic co-efficient 10 of friction in a non-aqueous lubricant composition when compared to an equivalent lubricant composition comprising no block co-polymer.Type: GrantFiled: May 10, 2017Date of Patent: July 11, 2023Assignee: EQUUS UK TOPCO LTDInventors: Ian Stuart Hobday, Aitziber Viadas Cienfuegos, John Eastwood

Patent number: 10800993Abstract: The present invention relates to a lubricated system comprising: a) a component comprising a first surface which is a diamond-like carbon (DLC) surface; b) a component comprising a second surface; and c) a lubricant formulation interposed between the first surface and second surface. The lubricant formulation comprises: i) a base stock; ii) a molybdenum compound; iii) an organic polymer comprising a hydrophobic polymeric sub unit selected from polyesters and functionalised polyolefins and a hydrophilic polymeric sub unit selected from polyethers; and iv) optionally, other additives. The combination of the molybdenum compound and the organic polymer in the lubricant formulation reduces the wear on one or more of the surfaces in the lubricated system when compared with using the molybdenum containing friction modifier alone.Type: GrantFiled: March 14, 2017Date of Patent: October 13, 2020Assignee: Croda International PLCInventors: Gareth Moody, John Eastwood, Aitziber Viadas Cienfuegos

Patent number: 4071643Abstract: This invention is the production of a plain bearing having an aluminum interlayer and a metal overlay on the interlayer. The overlayer is for example cast on the interlayer so that it can constitute substantially the final bearing surface without machining after casting or roll-bonding. In order to enable the overlay to be cast on, the interlayer is abraded while below the surface of a tinning or other coating material in a material so that oxides can be removed from the aluminium surface and the coating applied to it without its becoming re-oxidised, and then the overlay can be applied to the coating.Type: GrantFiled: November 20, 1975Date of Patent: January 31, 1978Assignee: The Glacier Metal Company LimitedInventors: George Christopher Pratt, Barry John Eastwood, Anthony Dennis Michael, Leonard Heath
