Title: An improved combined billet-piercing and extrusion press
IPC: B21C23/21
Filed: 1953-09-25
Abstract: 753,506. Extruding j billet - piercing. SCHLOEMANN AKT.-GES. Sept. 25, 1953 [Oct. 14, 1952], No. 26432/53. Class 83 (4). An extrusion press, particularly for making hollow bodies 16 open at one end, has a piston 8 operating the extrusion ram 3, a piston 6 operating a billetpiercing mandrel 2 and an auxiliary piston 11 which assists the piston 6 during the piercing operation, the three pistons being disposed co-axially. The piston 11 carries a cross-head 12 which transmits pressure to a cross-head 5, carried by the piston 6, through rods 13. An adjustable stop 14 limits the forward movement of the auxiliary piston. The supply of pressure fluid to the pistons 6 and 11 may be controlled by a single lever and the supply to the auxiliary piston 11 may be shut off automatically when the crosshead 12 strikes the stop 14. After piercing the billet, the mandrel is moved forwardly during the extrusion by the piston 6 only. A U-shaped stripper 16 operated by a piston in a cylinder 17 severs the workpiece 15 from the discard remaining in the extrusion die 1, and holds back the workpiece during the withdrawal of the mandrel. The stripper may be controlled automatically by a switch actuated by the cross-head 5. Withdrawing cylinders are provided for the ram and mandrel. The end of the return movement of the ram and mandrel may be cushioned by a buffer or by throttling the escape of pressure-fluid from the cylinders of the pistons 6, 8, 11 or by admitting pressure fluid to the opposite ends of these cylinders. In an alternative embodiment two of the pistons may be disposed coaxially one within the other.

Patent GB-861921-A (GB)
Title: Selector circuits
IPC: H03K19/177
Filed: 1958-08-22
Abstract: 861,921. Electric selective signalling systems. STANDARD TELEPHONES & CABLES Ltd. Aug. 22, 1958 [Aug. 28, 1957], No. 27050/58. Class 40 (1). [Also in Group XL (c)] A selector circuit for obtaining outputs representing symmetrical functions of input quantities i, k (= 1, . . . n) comprises n inputs for each of the input quantities connected to (n+1)n/2 AND gates corresponding to the (i, k) combinations for i # k or i # k, quantity representing marking potentials being fed directly to the AND gates for i=k and to the remaining AND gates via decoupling elements, e.g. diodes. Fig. 3 shows a triangular matrix in which i, k are each represented by applying a negative or earth marking potential to one of inputs 1 . . . 9, 0. The inputs are connected directly to the AND gates along the main diagonal (corresponding to i=k) and via decoupling semi-conductor diodes such as G 3  to the remaining AND gates. Each gate comprises a pair of normally conducting diodes and a resistor as shown. When marking potentials are applied to a pair of inputs (e.g. i=1, k=3 or i = 3, k=1) conduction is prevented in the diodes of the corresponding gate (S 31 ), thus producing a drop in potential at the associated output point (P 31 ). In an alternative, the AND gates comprise two transistors and a resistor in series, the row and column lines being connected to the base electrodes. In another form of circuit, Figs. 2 and 4, for each " k " input, a single transistor T 1  is connected to a group of transistors controlled by the separate " i " inputs. Fig. 2 shows a known circuit comprising a group of ten base-controlled transistors connected to each of the " k " transistors such as T 1 . When a negative marking potential is applied to one input i and one input k, a pair of transistors, such as T 1 , T 01 , will be rendered conductive thus causing current to flow through a series connected resistor (R 01 ) and producing a rise in potential at the associated output point (P 01 ). In the circuit of the invention shown in part in Fig. 4, the number of transistors is reduced by connecting correspondingly numbered i and k inputs together through decoupling diodes such as G7, G8 as in Fig. 3, and also connecting the inputs directly to separate transistor gates (such as T<SP>1</SP>88, T<SP>11</SP>88) for i=k.
