Title: Method and apparatus for the cold-extrusion of articles with non-cylindrical bores
IPC: B21C23/10
Filed: 1957-04-24
Abstract: 865,581. Extruding. SCHONDELMAIER, C. April 24, 1957 [April 25, 1956], No. 12999/57. Class 83 (4). A hollow metal work-piece with a non- cylindrical bore (including substantially cylindrical bores containing fluting, grooves, and/or lands) is produced by extruding the work-piece through the aperture of an extrusion die of which the inner bore-producing mandrel is freely rotatable with respect to the outer die member, but is located axially relative thereto. A prebored blank 6 is inserted into the upper portion 5a of a channel in a die member 5 and a grooved mandrel 2 is inserted into the bore of the blank so as to project a short distance through the blank. A ram adapted to be moved relative to the die 5 comprises a cylindrical hollow head 1 having a bottom 1a (Fig. 1) from which a tubular ram member 1b projects for insertion into the upper portion 5a of the die-channel to exert a coldmoulding pressure upon the blank 6. The mandrel 2 is supported in and guided by the inner wall of the tubular ram member and has supporting members 3, 4 secured at one end to its head, the mandrel and supporting members extending through apertures 1c, 1d, 1e, respectively, in the bottom 1a of the ram head. These supporting members engage with the upper surface of the die-member 5 to limit the movement of the mandrel into the die channel to a point where its lower end extends slightly beyond the level of the lower end of the conical portion 5c. The blank and mandrel are free to turn relative to each other about the same axis and for this purpose the supporting members 3, 4 are provided at their upper ends with bearing-means which rotatably support the head of the mandrel. These bearing means may either consist of suitable anti-friction bearings or the supporting members may be provided with semi-circular head portions which engage in an annular groove 2c in the head of the mandrel and thus form a pair of slide bearings.

Title: A method of electrolytically coprecipitating metal oxides
IPC: C25B1/00
Filed: 1959-04-17
Abstract: 864,249. Forming mixed metal oxides electrolytically. MAGNETO-CHEMIE N.V. April 17, 1959 [April 17, 1958], No. 13127/59. Class 41. Mixed oxides of metals are prepared by electrolysis of an alkali salt solution using anodes of the metals the oxides of which are to be precipitated, the anodes being separated by insulating partitions, and being supplied with electric current proportional to the oxide content required in the co-precipitated oxide mixture. Oxygen or an oxidizing agent is present, especially in the cathode area, to prevent reduction of the oxides produced, e.g. by passing in air and ozone, or oxygen through a perforated tube immersed in the electrolyte or by adding H 2 O 2.  A porous carbon cathode may be used in the form of a tube through which air passes, but the cathode is preferably of Al, Ti, or Mg having an oxide film thereon, or surrounded by a porous envelope. In examples, a dilute solution of Na 2 SO 4 , KF and KHF, or NaCl is used as electrolyte and a little NaClO may be added as the oxidizing agent. The anodes used are :  (1) Zn and Cu with currents of 18A and 2A; (2) Sn and Ti with currents of 10A and 5A; (3) Zn, Mg, Mn, Co, Cd with currents of 1A, 1.5A, 15A, 0.4A and 0.65A respectively; (4) Fe and Mn using currents of 1A and 15A. In all cases the anodes were of the same size. The anolytes are vigorously stirred together before entering the cathode zone. The compositions of the oxide mixtures produced are specified. Specification 823,436 is referred to.

Title: Improvements in or relating to installations for automatically guided transportation vehicles
IPC: B62D1/26
Filed: 1968-03-19
Abstract: 1,215,232. Vehicle control system. H. JUNGHEINRICH & CO. MASCHINEFABRIK. 19 March, 1968 [23 March, 1967], No. 13300/68. Heading B7N. In an automatic control arrangement for vehicles each guided e.g. by a single sensing wheel engaged in an upturned U-shaped rail 8, a number of similar trackside circuits are provided such that a vehicle 32 is brought to a halt when a receiver 34 thereon receives a signal from a transmitter 30 of a vehicle 29 in advances via one of the circuits e.g. circuit 9 which includes a section 10 extending on one side of the guide rail and a second section 11 extending on the other side of the guide rail. Assuming movement from left to right each leading section of a circuit overlaps completely the rearward section of the circuit in advance and each rearward section of a circuit is completely overlapped by the leading section of the circuit in the rear. The vehicle transmitters 30, 33 co-operate with the leading sections of the circuits on the left of the guide rail and the receivers 31, 34 co-operate with the rearward sections of the circuit. The transmitters and receivers operate at the same frequency and to prevent a receiver obtaining a signal from its own vehicle transmitter the transmitters and receivers are energized alternately at a different rate on each vehicle. The circuit may be a loop as shown inductively coupled to the transmitting and receiving apparatus and tuned by capacitor 35 to the transmit frequency, or may be formed of conducting strips capacitively coupled to the transmitters and receivers, Fig. 5 (not shown), or may be a single conductor which with a conducting guide rail forms a circuit directly connected e.g. by brush means, with the transmitters and receivers, Fig. 6 (not shown). Taps on the loops may be connected to a display board to indicate the vehicle positions or may provide a signal to operate e.g. a door in advance of a vehicle.

Pneumatic and hydraulic springs. - Relates to vehicle shockabsorbers utilizing both air and oil, and comprises a casing with a main piston formed to provide an oil reservoir, a pump cylinder carried by the piston, a plunger connected to the casing operating therein, and an air inlet to the pump chamber, which is also connected to the oil reservoir by a restricted opening. The casing 1 is connected to the frame member 52, and the piston 3 to a spring 54. The upper end of the piston has an annular extension 7 supporting the pump cylinder 24 which is connected at its base to a valved plug 20 in a cross-member 16, below which is a vented supply chamber 15 connected with an annular channel 12 to receive oil passing outside the piston and held above the packing 17. The cylinder 24 has a restricted opening 26 connecting the oil-reservoir 19 with the pump chamber which is closed by a valved piston carried on a hollow piston-rod 27 secured to the cap 2, between which and the piston 3 is arranged a spring 36. An opening 34 connects the rod with the chamber 35, from which an oil return passage 39 leads to the reservoir 19. Road vibrations cause relative movement of pistons and cylinders, air being pumped thereby into the main chamber 35 through the valve 33 in the piston-rod 27, the pump chamber being supplied with air through the valved plug 20, while oil enters through the restricted passage 26, the oil acting as a variable base for pumping air. The cylinder 24 is slotted at 56 to restrict the pumping action. The pump cylinder mav alternatively be attached to the cap 2, and the piston-rod to the plug 20.
