Title: Improvements in or relating to fusing metal deposits on to wire and strip-like bases
IPC: C25D5/50
Filed: 1952-05-15
Abstract: 710,815. Electroplating. LANGBEINPFANHAUSER WERKE AKT.-GES. May 15, 1952, [May 15, 1951; April 28, 1952.] No. 12287/52. Class 41. [Also in Group XI] A wire or strip of iron, brass, copper or other metal after plating with another metal e.g. tin is heated by passage of electric current therethrough to a temperature just below the melting point of the deposit and is thereafter subjected to an additional intense heating in a considerably smaller zone and carried out by a different rapidly adjustable heating device to fuse the deposit. As shown the plated wire 1 is heated by alternating current passed therethrough between rollers 2, 4 connected to transformer 5 and fusion is effected by passage between radiant heaters 6, 7 heated by current from transformer 8. The coating is solidified by passage of the wire or strip through water bath 9. The heating device, such as 6, 7 may be displaced in the direction of the strip for adjustment on its distance from the strip may be varied. Infra-red radiation or inductive heating may be employed.

Title: Improvements in or relating to high speed logical circuits
IPC: H03K19/084
Filed: 1960-04-07
Abstract: 923,517. Semi-conductor switching circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 7, 1960 [July 20, 1959], No. 12330/60. Class 40 (6). In a logical circuit in which the inputs are applied through respective diodes or transistors and in which the output is capacitive, a transistor is connected to the output and is arranged to be conductive when all said diodes or transistors are non-conductive to provide at such times a low-impedance charging or discharging path for the output capacitance so as to permit rapid switching of the circuit. Fig. 3 shows a diode AND gate in which a positive output is developed when simultaneous positive inputs are applied so switching off both diodes 23 and 24. The junction point 25 goes rapidly positive so switching off diode 30 and switching on NPN transistor 31 through which the output capacitance 29 is rapidly charged to a positive potential. When either input goes negative, the load discharges through diode 30 in series with either diode 23 or 24. In Fig. 5, the simultaneous application of positive inputs at 61 and 62 causes transistors 63 and 67 to be switched off whereby the potential at point 72 rises to switch transistor 79 on and provide a lowimpedance charging path for the output capacitance 77. When either or both inputs go negative the appropriate one or ones of transistors 63, 67 resumes conduction and transistor 79 is switched off thus providing a low-impedance discharge path for the capacitance 77. Figs. 4 and 6 (not shown) illustrate OR-gates corresponding to the AND-gates of Figs. 3 and 5 and derived from them by reversing all the polarities of the supply voltages, connections of the diodes and conductivity types of the transistors. In an arrangement comprising AND-gates and OR-gates connected alternately in cascade, Fig. 7 (not shown), the auxiliary transistor of each circuit provides a low-impedance input for the succeeding circuit since when the input diodes or transistors of the succeeding circuit are conducting only the auxiliary transistor is likewise conducting in the preceding circuit.

Abstract: 821,737. Pistons. BENDIX AVIATION CORPORATION. April 24, 1957 [April 26, 1956], No. 13088/57. Class 122 (1). [Also in Group XXII] A method of securing a piston 10, Figs. 1 and 2, to a piston-rod 18 comprises inserting the piston-rod into a shouldered opening 12 in the piston so that its end engages the shoulder 16 of the opening, and deforming an annular ring 22 into locking position in a recess 20 in the piston-rod. The piston 10, shown in Fig. 1, is made of a deformable metal such as steel and has a counterbore 14 into which the piston-rod 18 is inserted so that its end abuts the shoulder 12; in this position, the recess 20 aligns with the ring 22 which is formed integrally with the piston. The piston and pistonrod so assembled are then mounted over a die block 24, Fig. 2, so that the piston-rod is disposed in the opening 26. With the piston-rod then biased upwardly by a spring to position the ring 22 just above a conical deforming surface 30 of the die block 24, pressure is applied by the descending ram 28 of the press to force the ring 22 downwardly into engagement with the surface 30 and deform it into firm fluidtight contact with the recess. In the modification, shown in Figs. 4 and 5, the piston 40 which is of a non-deformable material such as cast iron, is provided with a counterbore 46 forming a shoulder 48 against which the shoulder of a piston-rod 42 abuts and a recess 50 provided in the piston-rod aligns with a counterbore 52 in the face 60 of the piston. A malleable-metal two-part ring 54 is located in the counterbore 52 and recess 50. The assembly is then mounted in a press similar to that described above and the inclined surface 70 of an upper die-block 68 is forced downwardly by a ram into engagement with the ring 54 to thereby swage it into the recess 50. The abutting end of the piston-rod, its mating shoulder 16 or 48 in the piston, and the shoulder formed by the recesses 20 or 50 in the pistonrod may be in the form of a series of disconnected abutment surface portions instead of continuous surfaces as shown.
