Abstract:
A method for producing and commissioning a transmission with a water-based lubricant comprises the following steps. A mixture of a vaporizable liquid, a comminuted solid lubricant and a preserving agent (22) are applied (21) to the finished rotary parts (20) and then dried (23), whereby a coating forms on them. The rotary parts with the coating are installed in the transmission housing and the assembled transmission is filled with a cooling liquid (25), which is primarily essentially water. The transmission is put into operation for the first time (27), wherein the lubricant for the further operation is only formed by abrasion of the rotary parts and distribution of the abraded matter in the cooling liquid. The transmission is then ready for operation (28). Furthermore, a lubricant produced by this method is described.
Abstract:
The present invention relates to a process for preparing carboxyl-terminated polyisobutenes by ozonolysis of polyisobutenes terminated by an ethylenically unsaturated double bond.
Abstract:
This invention relates to a cleaning and lubricating solution for guns, gun bores, cartridges, and gun parts, and more especially for black powder guns, gun bores, cartridges, and gun parts. The solution is used to clean dirt and debris from the bores and other parts of black powder firearms and accessories. The solution cleans the bore and the residual material forms a protective coating or film of a light lubricating oil.
Abstract:
Tripivalate esters of polyhydric alkanols having 3 methylol groups attached to a single terminal carbon atom in a C2 to C8 alkane chain, especially the tripivalates of trimethylol ethane and trimethylol propane, are made by reacting the polyol with an esterifying derivative of pivalic acid, e.g. the chloride or anhydride. The examples include the syntheses of trimethylylethane tripivalate and the preparation of pentaerythritol tetrapivalate is also given, in both cases pivalyl chloride and pyridine being the reagents. Reference has been directed by the Comptroller to Specification 884,660.ALSO:Lubricating compositions including greases comprise a pivalic acid ester of a polyhydric alkanol having 3 or 4 methylol groups attached to a single carbon atom which when there are 3 methylol groups is a terminal atom of a C2 to C8 alkane chain. The lubricating composition may contain more than one of said esters and especially more than 5% of each. Specified components are trimethylyl ethane and propane tripivalates and pentaerithrityl tetrapivalate. The compositions may include antioxidants and/or anticorrosives, of which lists are provided. The examples give binary and one tertiary composition of pivalate esters. Named classes of additives include among others, 5-ethyl-10, 10-diphenyl phenazasiline, phenothiazine, diarylamines, aminophenols, dialkyl selenides and talmides, basic sulphonates, indium carboxylates, alkali and alkaline earth metal and polyvalent soaps, silica, silica aerogels, ammonium clays, indanthrene dyes, polymeric clays coated with resins or aniline graphite. Reference has been directed by the Comptroller to Specification 884,660.
Abstract:
An object of the invention is to provide a grease composition capable of keeping a good lubrication condition for a long period of time even when water has mixed therein, thereby inhibiting white structure flaking and corrosion. Another object is to provide a vehicular hub unit bearing which hardly suffers from white structure flaking and corrosion even when used in an environment where water may penetrate into it and which therefore has a long life.The invention provides a rolling bearing with, sealed up therein, a grease composition containing a waterproof film-forming additive added thereto; a grease composition for hub unit bearings, containing a base oil that comprises at least one of mineral oil and synthetic oil as the main ingredient thereof, and a thickener and a flaking inhibitor; and a vehicular hub unit bearing with the grease composition sealed up therein.
Abstract:
A process for the treatment or pretreatment of containers made of aluminum, aluminum-containing alloys, magnesium-containing alloys, iron-containing materials such as steel, coated iron-containing materials such as galvanized steel, or aluminum alloys, tinplate, brass or bronze, in particular the treatment or pretreatment of bags, tubs, bottles, cans, canisters, casks or tubes, wherein the process steps for the treatment or pretreatment take place at the same time as the application of the lubricant, with the agent used for the pretreatment or treatment, which also contains or is a lubricant, not essentially consisting of titanium or zirconium with fluoride and polymer, the lubricant possibly being formed first in the agent for the pretreatment or treatment or in the formation of the coating produced therefrom.

Abstract:
Mucilages and mucilage extracts are disclosed that are effective as water-soluble, non-toxic, biodegradable, environmentally benign lubricants and/or coolants for a variety of industrial and machining purposes. One embodiment of the invention is a cooling and/or lubricating composition comprises a sufficient amount of the mucilage to cool and/or lubricate a machining surface. Other embodiments further comprise a sufficient amount of a preservative to substantially inhibit degradation of the composition. Also encompassed within the scope of this invention are methods for making mucilage-comprising cooling and/or lubricating compositions, as well as concentrating and drying such compositions. Other aspects of this invention are methods for machining a surface, comprising extracting a mucilage, adding a sufficient amount of a preservative to substantially inhibit degradation of the mucilage to form a mucilage mixture, applying the mucilage mixture to a surface to be machined, and thereafter machining the surface. In another aspect, the invention provides methods for lubricating and/or cooling a machining surface comprising extracting a mucilage, adding a sufficient amount of a preservative to substantially inhibit degradation of the mucilage to form a mucilage mixture, and applying the mucilage mixture to the machining surface to act as a lubricant and/or coolant. A farther aspect of this invention is the use of plant mucilages to coat the outer hull of watercraft, thereby reducing friction and drag, and increasing the speed of the craft. Optionally, such a composition may further comprise a cream wax.
