A wiper blade is produced by molding a wiper blade matrix of ethylene-propylene copolymer (EPM) or ethylene-propylene-diene copolymer (EPDM) and fluorinating the matrix thereby causing fluorine atoms to be bonded to the carbon atoms of the copolymer in the surface layer of the matrix. The wiper blade possesses a low friction coefficient and is resistant to ageing, ozone, chemicals, and permanent s...

A rubber material laminated with nylon resin is produced in combination with a rubber material layer, an adhesive reinforced layer and a nylon resin layer, thereby enabling a very strong adhesion between the rubber material layer and the nylon resin layer. The rubber material comprises a rubber material layer mainly made of acrylonitrile-butadiene copolymer rubber, an adhesive reinforced layer whi...

A co-solvent accelerator for a polyamide-acid/ether solution which accelerates the conversion thereof to polyimide comprises certain high boiling polar aprotic solvents such as N,N- dimethylacetamide (DMAc) and the pyrrolidone-based solvents, especially those with a boiling point of above about 250 DEG C. Said co-solvents are employed in concentrations of from about 0.5% to about 10% by weight.

Solid silicate foams are produced from a composition which comprises an alkali metal silicate, a foaming agent, ethylene carbonate as hardening agent and water. The composition may contain a water-soluble metal silicofluoride such as zinc silicofluoride hexahydrate and/or magnesium silicofluoride hexahydrate as an auxiliary hardening agent.

A process for producing foamed particles of a polyolefin resin which comprises dispersing polyolefin resin particles in water in a closed vessel, feeding a volatile blowing agent into the closed vessel, heating the dispersion to a temperature above the softening point of the polyolefin resin particles but below their melting point, opening a discharge port provided within the closed vessel below t...

A vehicle gearbox has a brake for dampening idle rattling, which is in this case in the form of a conical frictional surface on the low-speed gearwheel on the output shaft and a brake cone carried by a disc fixed to the output shaft. The disc and the cone have coacting structure which presses the cone against the frictional surface when the low-speed gearwheel rotates more rapidly than the output ...

Inertial measurement of the angular rotation and translational motion of a structure can be provided by a pair of vibrating accelerometers 10, 12 aligned in a side-by-side arrangement with their force sensing axes A<1>z, A<2>z in the same plane and vibrated to and away from each other in that plane along an axis normal to their force sensing axes.
