Filed: 1972-11-14
Abstract: 1402733 Producing shaped plastics articles NITTO BOSEKI CO Ltd and JAPAN ATOMIC ENERGY RESEARCH INSTITUTE 14 Nov 1972 52530/72 Heading C3P A continuous process for producing shaped articles of fibre-reinforced plastics material comprises passing through a forming device a moulding material comprising a radiationcurable synthetic resin material, which is curable by a free radical cross linking mechanism, and a reinforcing fibrous material, and exposing the moulding material to ionizing radiation immediately after it leaves the forming device, while pulling out the thus shaped material by means of a pair of rollers. In a modification of the process, the surface of the moulding material is covered with a 25 to 200 Á thick film which is transparent to the radiation used, and the thickness or volume of the material is then adjusted as desired before the material is formed and cured. The curable resin material may be, for example, an unsaturated polyester, an acrylic resin (saturated or unsaturated), a diallylphthalate resin, polybutadiene, modified polybutadiene, or an epoxy or polyurethane resin which has been modified so as to introduce unsaturated groups therein. The reinforcing material may be a natural or synthetic organic fibrous material or an inorganic fibrous material, preferred examples of these being glass fibre, asbestos, polyester fibre and polyvinyl alcohol fibre. The moulding material may also include a filler and other additives such as colouring agents, mould release agents, thickening agents, curing catalysts and promoters, UV stabilizers and flame retardants. Useful forms of ionizing radiation include α-, #- and γ-rays, X-rays, and accelerated electron beams. The articles formed may have such shapes as plain flat panels, embossed panels, rods, rectangular bars, L-shaped bars and panels which are corrugated longitudinally or transversely.

Title: Method and apparatus for effecting negative point protrusion of a piston ring
IPC: F02F5/00
Filed: 1975-12-31
Abstract: 1487510 Bending piston rings DANA CORP 31 Dec 1975 [10 Jan 1975] 53351/75 Heading B3E The ends of a piston ring are bent inwards by heating the inside surface of the ring on either side of the gap and cooling the ring. Fig. 1 shows apparatus for carrying out the operation, comprising a slider 14 having a circular aperture in which the ring 22 is retained in a compressed state. The slider is then moved to the left by jack 16, so that electrodes 26, 27 contact the inner face of the ring, and electrode 28 bridges the ring gap. The electrodes are supported on water cooled carriers 31, 32. Current is passed between electrodes 26, 27, or from each to electrode 28, to heat the inner face of the ring, e.g. to 400 F., through less than half the ring thickness, e.g. about the innermost thickness, e.g. about the innermost 20%, for one half to ten seconds, preferably up to two seconds, at a power of 3 to 5 kilowatts at 450 kHz. The inability of the ring ends to bend outwardly during this heating results in yielding of the structure of the ring in compression along the inner face, whereby the ends bend inwardly when the ring cools. The ring ends may be prevented from bending outwardly merely by the unheated outermost portions thereof, the confinement of the ring providing further restraint.
