Abstract: The motor-driven unbalanced oscillating mechanism (1) can produce horizontal oscillations in a mass (2) without heavy vibration being transmitted to the machine foundations and, for example, to the building, in this case. In order to compensate for the mass forces, at least one pair of weights (4) is caused to rotate in mutually opposite directions of rotation, in synchronism with the oscillation frequency. The device (8) producing the oscillations, the mass (2) and the weights (4) are connected by a force fit. When the mass (2) is at its point of reversal, all the weights (4) are in a position on the circumference in which the direction of their centrifugal forces opposes the direction of the mass forces of the mass (2). In the vertical position, the centrifugal forces of the weights cancel each other out. <IMAGE>

Abstract: A polishing pad material is provided with a cellular polymeric layer containing elongated cells normal to the major surfaces of the material, such that the cell openings on the polishing surface of the material comprise a majority of the surface area, and the cells have a mean diameter of about 50 to 200 microns with the diameter of the surface openings being preferably larger than the cell diameters below the surface. The cells are preferably cone-shaped and have a depth at least 1.5 times the diameter of the surface openings. The pad material is formed from a poromeric material, preferably polyurethane elastomer, with microporous cell walls having pore diameters less than 0.1 times the diameter of the cells. The polishing pad material may be made according to conventional poromeric technology, but instead of removing the usual top poromeric skin, the poromeric layer is inverted and the original bottom poromeric skin and any attached substrate are removed to open and expose the cells at a plane corresponding to their largest diameters.

Abstract: Graft polymers in which vinyl carboxylates and optionally further ethylenically unsaturated monomers are grafted polymerically onto polyurethane backbones by free-radical-initiated graft polymerisation, and products of the hydrolysis of the graft polymers, can be obtained by grafting vinyl carboxylates having 3 to 20 carbon atoms and optionally further ethylenically unsaturated, polymerisable and optionally copolymerisable monomers in amounts of from 10 to 99% by weight, based on the graft polymer, onto a polyurethane backbone containing at least 2 urethane groups in the molecule, and, if desired, subsequently partially or fully hydrolysing and/or alcoholising the vinyl ester units and any further hydrolysable monomer units in the grafted-on polymer radicals of the graft polymers. Vinyl esters which are preferred for grafting are vinyl acetate and/or vinyl propionate and possibly vinyl versatate. The graft polymerisation is carried out in solution or in bulk and can also be carried out in emulsion or suspension. Unhydrolysed graft polymers are suitable, inter alia, as adhesives, in particular as hot-melt adhesives. Fully and partially hydrolysed graft polymers are suitable, inter alia, for the production of films. Depending on the polyurethane backbone, the degree of grafting, the degree of hydrolysis and the type of grafted monomers, the graft polymers, compared with polyvinyl alcohol, can have significantly lower melting points, and are thus advantageously suitable for the production of pressed or extruded films under mild temperature conditions without the additional use of organic plasticisers. Hydrolysed graft polymers are furthermore suitable, inter alia, as adhesives.
