Abstract: 467,988. Forging-machines. FINZEL, H. Dec. 27, 1935, No. 35824. Convention date, Dec. 31, 1934. [Class 83 (iv)] Dies.-In apparatus for forging in which both the work and tool holders are used as electric conductors for heating the work pieces which are successively acted on by the tools, the holders are moved toward one another after each rotary movement so as first to close the circuit through the work piece thereby heating same, and then successively deforming the work by the tools. As shown, a press ram 7 carries a series of tools 17 of which one is spring pressed at 20 and insulated at 18 leaving a conducting space 19, by which current can pass from conducting elements 15, 14 in the position shown in the drawing.

Filed: 1972-08-01
Abstract: 1398623 Paper comprising polyolefin fibres CROWN ZELLERBACH INTERNATIONAL INC 1 Aug 1972 [2 Aug 1971] 35936/72 Heading D2B [Also in Division C3] Paper-like products are obtained by forming a web of polyolefin fibres from an aqueous slurry thereof and drying the web, the aqueous slurry of polyolefin fibres being prepared from a mass of polyolefin fibres in an organic liquid by heating the mass combined with water and in the presence of polyvinyl alcohol, to vaporise and remove the organic liquid from the fibres. The polyolefin fibres may be of polyethylene or polypropylene, obtained by polymerisation in a hydrocarbon or halogenated hydrocarbon which is a solvent for the monomer and which swells the polymer. The resulting fibrous gel may be passed through a disc refiner and non-sorbed solvent separated by centrifuging or filtering. Loss of fibre surface area on solvent evaporation may be reduced by adding to the water a surface active agent having an HLB of at least 10, preferably a non-ionic surface active agent. The resulting slurry may be dewatered and redispersed in water before use in paper making. In examples hand sheets are made from aqueous slurries obtained by mixing masses of polyethylene fibres in hexane with aqueous polyvinyl alcohol solution and heating to drive off the hexane.

When a record in its jacket 3 is received in jacket receiver 20 an opening mechanism 24 is actuated to move the jacket sides apart. A solenoid 21 can then tilt the receiver so that the record rolls out along guide 16 to the turntable 10 where it is stopped by stopper 17 with its centre hole concentric with the turntable. This position of the record is detected by a sensor 28 and this actuates a device 13 which operates a record clamp 12 to secure the record to the turntable. The record is then transduced by a device 15. At the end of the playback operation a solenoid 23 is operated to move the jacket receiver so that the jacket opening is disposed at the end of guide 18, which can be formed of a resilient and high friction factor material, and the clamp 12 is released so that the record drops on to the guide and by virtue of its rotational momentum runs up the guide into the jacket. A circuit for controlling the various solenoids &c. is described with reference to Fig. 9 (not shown). Figs. 10-12 and 36-39 (not shown) illustrate arrangements in which the record is rotated in a horizontal plane; Figs. 13-17 and 20-22 (not shown) illustrate different forms of guide member 18; Figs. 18, 19 and 24-26 (not shown) illustrate different forms of record clamp; Fig. 23 (not shown) illustrates an arrangement for stopping rebound of the record from its jacket; and Figs. 27-35 (not shown) illustrate various jacket opening devices.
