Title: Improvements in or relating to the manufacture of thin metal laminae
Inventor: MAYER SIMON ERNST
IPC: B22F3/02
Filed: 1948-07-05
Abstract: 679,174. Moulding thin metallic laminae. STANDARD TELEPHONES & CABLES, Ltd. July 1, 1949 [July 5, 1948], No. 18011/48. Class 87(ii) Finely - divided metallic powder is passed through one or more fine mesh sieves, whereby the powder becomes thoroughly aerated, and then poured into a die having a horizontal base plate 1 normally rigidly attached by wedges 3 to vertical side walls 2. The side walls 2 are higher than the base plate 1, thus forming a die cavity. The excess powder is then scraped off level with the upper edges of the side walls, and a ram 6 which is a close fit in the side walls is forced downwardly into the die cavity under high pressure, whereby the volume of the aerated powder is greatly reduced and the powder is compressed between the elements 6, 1, to form a lamina. The ram is then withdrawn from the die cavity, and the base plate 1 is released from the side walls by withdrawing the wedges and then raised to enable the lamina to be removed. 'To prevent damage to the lamina during removal, the upper portions of the side walls are tapered outwardly. The excess powder may be scraped off by a knife which is vibrated at say 50 cycles per second to prevent powder adhering thereto and thus scoring the surface. As the ram descends, powder may be blown out of the die cavity by displacement of air; to prevent this, the surface of the powder may be protected by a thin sheet of paper or. plastic material which is stripped from the lamina after discharge. The powder may be magnetic. The lamina may be circular and may be used as a telephone diaphragm, or may be in other shapes for use in transformers or inductance coils. Specification 679,172, [Group II], is referred to.

[Class 100 (ii)] Inking-apparatus.-In inking-mechanism for planographic printing- machines comprising at least two forme-engaging inking-rollers, one of these inking-rollers is geardriven and another, which acts subsequently against the forme, is frictiondriven. The forme roller 11. Fig. 2, is inked by two rollers 60, 61, of which the roller 60 is driven by gears 102, 146 from the shaft 10 of the forme roller, and the roller 61 is driven frictionally from the roller 60 through a longitudinally reciprocating distributing-roller 63. Ink is transferred from a fountain 81, provided with an adjustable flexible blade, to the roller 60 by means of a ductor roller 86, which is carried by spring-pressed arms 87 oscillated by a cam 109 on a shaft 108 driven by gearing 107, 104 from the gear 102. The fountain roller 83 is rotated by pawl-andratchet mechanism actuated by an eccentric on the shaft 108. The effective throw of the pawl is regulated by an adjustable shield to vary the amount of ink taken by the ductor roller, and the shield is held in its various positions by a spring pin engaging notches in its edge. The distributing-roller 63 is hollow and slides and rotates on a fixed shaft 70, Fig. 3, to which is fixed a bevel gear 77. A bearing block 73 is rotatably mounted on the shaft 70 and carries a bevel gear 76 engaging with the gear 77 and eccentrically pivoted to a link 90, which is pivoted to the roller 63. Rotation of the roller thus draws the block 73 after it, rotates the gear 76, and thus reciprocates the roller 63 axially. Damping-apparatus for lithographic machines. -Ink repellent is supplied to the forme roller 11, Fig. 2, by a roller 46, ductor roller 50, and a normally stationary roller 41 around which several layers of wick material 42 are wrapped, leaving an end hanging down into a reservoir 40 and adjustable to vary the length submerged by turning the roller 41. The ductor roller 50 is actuated through linkage 111-114 from the same cam 109 as the ductor roller 86 for the inking-apparatus. A cam plate 150 can be adjusted to trip the roller 46 and render the repellent-applying apparatus inoperable.

Abstract: 847,789. Transistor pulse shaping circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 27, 1959 [Aug. 28, 1958], No. 18071/58. Class 40(6). A circuit for widening a signal and strobing it during a predetermined period comprises a transistor stage to which the input signal is applied to saturate it only during a period determined by a strobing signal to produce an output signal having a width which is a function of the time during which the transistor stage is saturated. In the circuit shown in Fig. 1 an input signal A, Fig. 2, comprises a wanted component C and a noise component B. The signal is applied via emitter follower stage T3 to the base of a widening and strobing stage Tl which conducts only when transistor T2 is switched on by strobe pulse D, Fig. 2, which is timed to start only after the noise pulse B has terminated. When the input signal A is present and transistor T1 is conductive the forward bias between the base-emitter junction of transistor Tl is so large that the transistor saturates due to minority carrier storage effect and remains saturated so that the collector voltage returns to the collector supply voltage level only after a delay depending upon the degree of saturation, i.e., it is a function of the time that the input waveform has been applied. The output voltage E at the collector of transistor Tl is clamped by diode Dl and is applied to an AND gate comprising diode D3, D2 to the input terminal 19 of which are applied read pulses F which function as clock pulses to produce an output signal at terminal 17 only during their coincidence with the voltage E.
