摘要:
The invention concerns an improvement in the process for the production of dispersions of diorganopolysiloxanes and lubricant-acting inorganic silicates in water, whereby these dispersions contain, in addition to the above-mentioned substances, lecithin and nonionic emulsifiers, as well as solvents, ionic emulsifiers, lubricants other than inorganic silicates and diorganopolysiloxane, bactericides, fungicides, thickeners, antifoaming agents, rust inhibitors and dyes. The improvement is achieved by emulsifying the lecithin, nonionic emulsifier and water with each other before this mixture is mixed with at least 80% by weight of the diorganopolysiloxane contained in the finished dispersion, and, optionally, lubricants other than inorganic silicates and diorganopolysiloxanes. Furthermore, the invention concerns the application of the dispersions produced according to the invention as release agents, especially as inner tire release agents.
摘要:
Metal working operations, especially drawing, are facilitated by applying to the metal a composition which provides lubricity thereto and which melts within the range of about 30.degree.-100.degree. C. The composition comprises at least one neutral ester, and preferably a mixture of esters, prepared from polyalkylene glycols and saturated aliphatic alcohols having at least about 10 carbon atoms, and C.sub.12-25 aliphatic monocarboxylic acids and C.sub.4-20 aliphatic polycarboxylic acids. The preferred ester mixtures are prepared from polyethylene glycols, C.sub.14-20 predominantly straight chain alkanols, stearic acid and adipic, azelaic or sebacic acid. Optional ingredients include phosphorus acid salts and antioxidants. The composition may be applied in liquid form and solidifies on cooling to normal ambient and storage temperatures.

Compositions of 1,3,5-tris-(furfuryl)hexahydro-s-triazine are useful as antimicrobial agents particularly when added to metal-working compositions subject to fungal and bacterial attack.
摘要:
Improved internal combustion engine lubrication is obtained by the controlled rate of release of certain solid particles into circulating lubricating oil. Compositions are set forth comprising such solid particles combined with solid thermoplastic polymer having a controlled rate of dissolution in the lubricating oil. Also included are methods and apparatus wherein such solid particles are added to the engine lubricating oil, for example, which involve the filtering system for such oils.
摘要:
Antifriction compositions useful for bearings comprising poly(arylene sulfide), a solid lubricating component, a reinforcing material, and a filler in which the commonly employed antimony trioxide filler is replaced in whole or in part by a replacement filler of calcium carbonate, titanium dioxide, barium sulfate, hydrated aluminum silicates, red iron oxide, carbon black or diatomaceous earth, compatible with the other components.

A method comprising the application of colloidally suspended graphite emulsified in water as a parting agent to hot surfaces and in particular to ladles to facilitate pouring therefrom and the formation of sound castings.
摘要:
A time fuse for a non-spinning projectile has a pivoted catch connecting a fuse setting member to a setting disc whereby rotation of the member rotates the disc to wind a clockwork spring. A plunger is locked in a housing in the setting member by a movable ball or spring held by a spring-urged inertia block. When the fuse is set, the plunger acts on the catch to disconnect the disc and member upon displacement of the inertia block in response to axial acceleration of the projectile in a piece of ordnance.
