Abstract: This disclosure relates to a self-sealing pneumatic tire with puncture sealing properties and a method of manufacturing such a tire. The puncture sealant properties of the self-sealing tire are provided by a layer comprised of a blend of a crosslinked polymeric material and an irradiation degraded polymeric material. The method of this disclosure comprises providing a layer of rubber compound with a blend of polymeric materials, one of which degrades upon exposure to irradiation and another which crosslinks either on exposure to irradiation, by chemical reaction at vulcanization temperature, or both, assembling the layer into an unvulcanized tire in situ with the polymeric materials unaltered, vulcanizing the tire without altering the degradable polymeric material and irradiating the tire whereby the degradable polymeric material is degraded to a low viscosity to form a tacky material and the crosslinkable polymeric material is crosslinked to form an elastic matrix for the degraded polymeric material, whereby the layer has puncture sealing properties.

Title: Three=phase sinusoidal voltage generating system - uses two DC voltages and adds two phase-shifted triangular reference voltages
IPC: H03K6/00
Filed: 1979-11-30
Abstract: The generator produces three alternating voltages, phase-shifted by 120 deg., of equal and constant amplitudes from two equal and constant direct voltages of opposite polarity, using electronic switches. A first triangular alternating reference voltage (UD1) of constant amplitude, equal to the direct voltages (+UA, -UA), is generated. A second triangular alternating reference voltage (UD2), displaced in phase by 120 deg. w.r.t. the first reference, is generated and is added to the first reference voltage in a specified manner. Non-linear networks are used to produce two sinusoidal voltages (UR, UT) phase-shifted by 120 deg. from the two reference voltages.

Title: Method and device for removing a ring traveller from the ring of a ring-spinning or ring-twisting frame
IPC: D01H17/02
Filed: 1980-09-12
Abstract: A tool is supported by a support face on the upper side of a spinning or twisting ring, with a bearing face bearing on the outer edge of the ring. A hook engages by a tip below the inner end of a ring traveller, which is brought into a predetermined position by a permanent magnet let into a support part. By actuating the tool, the hook is moved in the direction of the support face, so that it lifts the ring traveller over the inner edge of the ring. After passing over the inner edge and due to its spring action, the expanded ring traveller jumps into a channel, which leads to a collecting container. With such a removal of the ring traveller from the ring, the yarn drawn by the ring traveller remains undamaged.

Patent ES-8200827-A1 (ES)
Title: Method of rolling a length of metal bar or wire and apparatus for carrying out the method.
IPC: B21B39/00
Filed: 1981-01-20
Abstract: At the end of a hot-rolling train a metal length (WS) (bar or wire) is passed through a final roll stand (W) and then through a cooling device (K). To keep the length under tension in the cooling device (K), it is pulled frictionally by an opposed pair of bridle rolls (R1, R2) which are driven, while the length is passing, with a power input which would in the absence of the length, be sufficient to cause a peripheral speed of the bridle rolls (R1, R2) slightly higher than the rolling speed of the length. To prevent the leading end of the metal length being twisted or otherwise damaged on entry into the bridle rolls, the bridle rolls (R1, R2) are driven at a slightly higher peripheral speed immediately prior to the entry of the metal length.
