Abstract:
The present invention provides a friction control composition comprising a binder a rheological control agent, and optionally a lubricant. The liquid friction control composition may also comprise other components a wetting agent, a consistency modifier, and a preservative. The liquid friction control compositions may be used to modify the interfacial friction characteristics in sliding and rolling-sliding contact such as steel wheel-rail systems including mass transit and freight systems. A method of reducing lateral force, reducing energy consumption, or controlling friction between a metal surface and a second metal surface by applying the composition to metal surface, for example a top of rail or wheel, is also provided. The composition may be sprayed onto the rail surface.
Abstract:
The disclosed invention provides a composition that possesses insulation values approaching that of uncompressed foam neoprene. The liquid composition is incompressible and may be formulated to be neutrally buoyant in water. The composition is suitable for a use in a number of applications where insulation is required, including divers' suits and underwater cabins, such as chambers, submersible hulls, and waterproof housings.

Abstract:
A threaded joint for steel pipes comprising a pin 1 and a box 2 each having a contact surface comprising a threaded portion 3 or 4 and an unthreaded metal contact portion 8 is provided with improved anti-galling propertied by forming a lubricating coating on the contact surface of at least one of the pin and the box, the lubricating coating exhibiting a self-repairing function by liquid lubrication and having a decreased greasiness. The lubricating coating is (1) a coating which comprises a lower lubricant layer which is in liquid form in the temperature range of above 0null C. and below 40null C. and an upper lubricant layer which is in solid form at 40null C., or (2) a coating which is semi-solid or solid at 40null C. and is formed of a mixture comprising a lubricating oil which is in liquid form in the temperature range of above 0null C. and below 40null C. and a wax which is in solid form at 40null C., the mixture preferably having been heated so as to liquefy the wax and dissolve in each other the wax and lubricant oil.
Abstract:
The performance of a paint ball marker is improved by applying a permanent lubricating agent to selected working parts of the marker in place of petroleum-based lubricants using known processes for applying metals, ceramics, graphite and various polymers to such working parts.
Abstract:
The present invention provides a rolling apparatus comprising a movable member which can undergo rotary or linear motion, a support member which carries the movable member, rolling elements which are interposed between the movable member and the support member and which roll with the movement of the movable member, and a lubricant composition which is disposed between the movable member on which the rolling elements roll and the support member, wherein the lubricant composition is a mixture of (1) a thickening agent which is at least one selected from the group consisting of a solid fluoropolymer, a lamellar mineral powder, an ultrafinely particulate organic material, an organic solid lubricant and an ultrafinely particulate inorganic material, and (2) a base oil comprising a liquid fluorinated polymer oil.
Abstract:
The present invention provides a grease composition which is excellent in peel resistance, not to mention lubricity, as compared with the prior art products. A novel grease composition for rolling bearing is provided, comprising a base oil, an extender, an inorganic compound-based filler having an average particle diameter of not more than 2 &mgr;m and zinc dithiocarbamate.
Abstract:
The invention relates to a lubricant which can be used as a mandrel lubricant with a content of 75 to 90 wt. % of graphite and contains 1 to 10 wt. % of a phosphate. Said lubricant can also contain 1 to 4 wt % alkali silicate, 1 to 10 wt. % bentonite, 0.5 to 1 wt. % silico-phosphate and common solid lubricants. Said lubricant is preferably used as an aqueous suspension with a solid content of 20 to 40 wt. %.
Abstract:
Low bleed silicone grease compositions are prepared by blending high viscosity silicone oils with filler materials and/or silicone elastomers. Greases comprise three main types: I) grease comprising high viscosity silicone oil and filler material, II) grease comprising high viscosity silicone oil and silicone elastomer, and III) grease comprising high molecular weight silicone oil and filler material and silicone elastomer.
Abstract:
A heat resistant grease composition containing a fluorosilicone base oil, a fluororesin thickener and an additive, that has a reduced gelling, reduced base oil evaporation, and stable heat resistance.
