Title: Foamed materials having non-foamed skins
IPC: B29C44/22
Filed: 1970-05-15
Abstract: 1313922 Moulding skinned foamed articles NAGOYA RUBBER CO Ltd 15 May 1970 [15 May 1969 (2)] 23603/70 Heading B5A [Also in Divisions B7 C3 F2 and H5]  Foamed material having an unfoamed skin is made by subjecting foamable polar natural or synthetic rubber or natural or synthetic rubber blended with carbon black to dielectric heating whilst externally cooling it. The material thus formed has a vulcanized foamed core and an unvulcanized or partially vulcanized non- foamed skin and is heated to a temperature below the foaming temperature or under a pressure higher than the foaming pressure to cause the skin to become fully vulcanized but unfoamed. The material may be a rubber, for example a chloroprene based material, a material based upon a mixture of styrenebutadiene rubber and acrylonitrile butadiene rubber, or an acrylonitrile butadiene based material. The foaming and heating may or may not be effected within a mould. In one embodiment (see Fig. 3, not shown) an extruded strip is passed through a steam boiler in which the external unfoamed layer is cured. In a second embodiment (see Fig. 4, not shown) a conical mass of foamable material is made, subjected to microwave radiation and finally externally heated in a metallic mould. In a third embodiment (see Fig. 5, not shown) a foamable material is placed within a non-metallic, non-polar mould, for example of glass fibre reinforced polyester, PTFE, cross-linked polythene, glass or ceramic, and the mould located in a microwave field, the mould then being further externally heated by infra-red radiation. In a fourth embodiment (see the Figure) an extruded strip 13a of foamable material is forced through a cooling gas or liquid 15 contained in a non- polar tube 16a itself located within a microwave oven 14a, and then through a secondary heating oven 19.

Filed: 1972-05-22
Abstract: 1344418 Automatic control UNITED AIRCRAFT CORP 22 May 1972 [27 Sept 1971] 23980/72 Heading G3R In a rectroactive control system, error signals V 1 , V 2  are fed respectively to operational amplifiers 46, 58 which have a common feedback loop including a load 52 controlling e. g. a servovalve in an autopilot. Under normal conditions, error signals V 1 , V 2  are equal and, due to the characteristics of each amplifier and its feedback components, one amplifier e.g. 46 saturates and amplifier 58 assumes control using error signal V 2 . If, due to a fault, V 1  increases, amplifier 46 remains saturated and amplifier 58 maintains control, but if V 2  increases with the same polarity as V 1 , amplifier 58 saturates and amplifier 46 maintains control using signal V 1 . If however, V 2  increases to an opposite polarity than V 1 , both amplifiers saturate in opposite directions, no current flows in load 52 and the controlled device assumes its null position. Resistors 50, 62, 68 provide current limiting. Current amplifiers 48, 60 may be inserted in the feedback loops between the amplifiers and the load.

Filed: 1932-09-02
Abstract: 407,067. Twisting wires together. COTCHETT, J. G., 160, Cromwell Road, Earl's Court, London.-(Wright, I. B.; 1517, 34th Street, Seattle, Washington, U.S.A.) Sept. 2, 1932, No. 24439. [Class 83 (iv).] Shearing adjuncts.-In a machine for securing wires round packages, the wire is applied by arms which rise over the top of the package and bring the ends into overlapping relationship, and the wire is twisted by mechanism carried on one of the arms. Packages are introduced into the machine on a roller table and arrive upon a platform 7, Fig. 3, within a vertically reciprocable frame 4. The frame is lowered to depress the level of the top of the package to that normally occupied by the platform, the latter meanwhile moving downwards against spring pressure. During the descent, arms 41, 42, turn upwards and inwards to train the wire over the package, and twisting apparatus 57, Figs. 3 and 8, carried by the arm 42 operates to unite the ends of the wire, after which the tied package is ejected. The overlapping ends of the wire enter through a slot 99, Fig. 11, into engagement with a slotted pinion 103, Fig. 8. The wires are held on each side of the pinion by fixed jaws 101 and movable jaws 102 operated at the appropriate times by springs 109 and cams 106. The cams are arranged on a counter-shaft 107 driven by reducing gear 108 from the central shaft 58. The shaft 58 is driven by the engagement of a mitre gear 59 with another 62 on a shaft 61 connected with the main drive, this engagement takes place when the arm 42 has been moved into its operative position and ceases when withdrawal commences. The gear 59 is stopped in the exact position necessary for engagement by a spring urged locking pin 124. Cutter bars 111 sever the wire at the end of the twisting operation. The slotted pinion 103 is rotated a fraction of a revolution beyond four revolutions and is then returned into register with the receiving slot so that disengagement takes place readily when the arm 42 is moved away. The shaft 61, which drives the pinion, is driven from a shaft 63, Fig. 3, having a gear 68 meshing with the toothed portion 71 of the wheel 21. At the end of the rotation, the leading wing tooth 117, Fig. 6, passes over a curved portion 116 and into a recess 119, which causes the shaft 63 first to exceed the exact amount of rotation required and then to reverse slightly.
