Abstract:
The pasty damping agent is used to damp mechanical and/or acoustic oscillations. The agent contains as a minimum compound a solid finely divided substance or a mixture of solid finely divided substances, as a liquid phase, a silicone oil, a polyglycol, a mineral oil and/or a saturated or aromatic aliphatic carbon dioxide ester, an agent for increasing the activity of the limit layer or a surfactant, a magnesium and/or aluminum silicate and/or a silicon dioxide finely divided as a viscosity stabilizer and possibly a small quantity of an empty oxidiser. The damping agent is used in different hydraulic damping devices or for industrial vibration shock absorbers.
Abstract:
The bearing material produced by impregnating in the porous metal or alloy layers, for example, copper or copper-like alloy layers formed by known means, for instance by sintering on the back of a metal plate such as steel, a composition containing 1 to 30% by volume of one or both of a lead-tin alloy, which contains 1 to 25% by volume of lead fluoride and 3 to 30% by weight of tin, and lead wherein the total of the said lead fluoride and lead is 2 to 35% by volume and, as the residual part, polytetrafluoroethylene (PTFE). The capacity of the bearing may be further improved by adding about 0.1 to about 5% by weight of at least one member of the additives consisting of molybdenum disulfide, tungsten disulfide, cadmium oxide, aluminium oxide, calcium fluoride, lithium fluoride, graphite, lead iodide, glass fibre, carbon fibre and phosphates. The bearing is especially suitable for being applied to the shock absorber of vehicles moving under changeable load.
Abstract:
The invention concerns a threaded portion of a tubular element for a threaded tubular connection hiving an axis of revolution, the portion comprising a threading extending over its outer or inner peripheral surface, and a first sealing surface on the peripheral surface, the first sealing surface being capable of producing metal-metal interference with a corresponding second sealing surface belonging to a complementary threaded portion of a tube. The threading and the first sealing surface are coated with a metallic anti-corrosion and anti-galling layer wherein zinc (Zn) is tie major element by weight.
