Filed: 1962-04-04
Abstract: 962,680. Transistor switching circuits. SONY CORPORATION. April 4, 1962 [April 8, 1961], No. 12976/62. Heading H3T. A transistor logic circuit element comprises a pulsed power supply connected across the emitter-collector path of a pair of transistors having inputs connected to each base electrode and outputs taken from each collector and is characterized in that an output signal is produced for the duration of a pulse from the power supply, the polarity of the output signal being determined by that of the input signal. Referring to Fig. 1, a reciprocally coupled pair of transistors 8, 9 are connected to a pulsed supply 1, and produce across terminals 17, 18 a pulsed output the phase of which depends on which of the two transistors is rendered conducting by an input pulse connected across terminals 15, 16. If terminal 15 is positive and terminal 16 negative, transistor 8 will conduct, and the output pulse will be produced with terminal 18 positive with respect to terminal 17. In a second embodiment, Fig. 3, the cross coupling resistors are omitted, and each transistor 8, 9 is biased by a respective diode 21, 22 so that it is normally cut-off and no output is produced in the absence of an input applied to terminals 15, 16. In modifications of the above-mentioned circuits, Figs. 5, 6 (not shown), the two transistors have their bases biased by respective backward diodes and are coupled to a common emitter resistor to prevent saturation in the conducting state.

Patent GB-131633-A (GB)
IPC: B21B33/00
Abstract: 131,633. Acieries Reunies de Burbach Eich-Dudelange Soc. Anon., and Metz, N. June 27, 1918. Rolling.-Rolling-mills are so constructed that the pressure between the rolls can be relieved instantaneously when desired by causing the bearing pressure or thrust to pass through a mass of steel balls, rollers, or other bodies in a vessel' upon which rests a piston-like cover which is displaced to allow the pressure to be relieved by letting the balls or rollers fall out of the vessel, or letting them sink to a lower level in the vessel by withdrawing laterally a wedge or like member which forms part of the vessel. In its simplest forms, a cylindrical or annular piston rests on balls in a vessel provided with a plug which can be removed to allow the balls to fall into a. separate receiving vessel, but in the forms shown in Figs. 6 and 10, the receiving vessels f are respectively secured by screws to the main vessel a in which the piston c rests, or are cast integral with the vessel a and separated therefrom by a plug d which is operated to release the balls when desired. A poker as i is provided to cause the balls to continue to flow in the case of a jam. In Fig. 10 the poker i is shown operated from the bottom by a lever m. As shown in Fig. 12, the piston-like member c is formed to receive a breaking-piece r, and the member c is formed with a flange which rests on the balls r, the member c itself forming one side of the annular container for the balls. The vessel f is attached by screws to the container, and a flanged retaining-ring e is used to connect the ports c, a during transit of the parts. Screwed caps may be employed to close the vessels a, f normally, these caps being unscrewed to fill or empty the vessels when desired. In a further modification, a piston as c, Fig. 12, is bored centrally and supports directly the cap-bolt connecting the head of the rolling mill frame with the frame itself, and in a further modification of this arrangement, the vessels a, f, are constructed integrally, as shown in Fig. 10. As shown in Fig. 18, the plugs d are dispensed with and one or more wedges u are withdrawn by means of a rod v when the pressure is to be relieved. The rod v is operated by levers or screws. The invention may be applied to a roll frame in which the pressure between the rolls is adjustable by means of a screw-operated wedge 9, Fig. 20, and a fixed wedge which transmits pressure to a bracket 13 which receives the pressure from the rolls. A cover 3 arranged over a set of balls in a recess 2 normally supports the bracket 13, and when the pressure is to be relieved the balls are let out into an auxiliary chamber (not shown), as described in the other modifications. In further modifications the balls &c. are arranged in vessels the bottoms of which are closed by counterweighted, or spring-pressed pistons which move under a given pressure to release the balls automatically, and the wedge u of Fig. 18 may be similarly controlled. The balls, rollers &c. are preferably annealed at a temperature of 400 to 500‹ C.

Abstract: 1,012,696. Automatic voltage control. WESTINGHOUSE ELECTRIC CORPORATION. April 1, 1964 [April 30, 1963], No. 13394/64. Heading G3R. A voltage regulating system for a dynamoelectric machine includes buck and boost amplifiers associated with an excitation winding of the machine. As shown, an exciter system 10 for an alternator 20 having a field winding 16 comprises a self-excited D.C. generator 14 the field winding 12 of which is connected in series with a rheostat 30. The output of a boost amplifier 40 is connected across the field winding 12, and the output of a buck amplifier 50 is connected across the rheostat 30. The input to the amplifiers 40, 50 is derived from a control circuit 70 which produces an error signal in dependence upon variations in the output voltage of machine 20. The arrangement is such that the boost amplifier 40 and the buck amplifier 50 co-operate to vary the field current of generator 14 in response to the error signal from circuit 70, whereby the output of generator 14, and thus the excitation of machine 20, is varied in a sense to maintain constant the output voltage of the machine 20. A feedback circuit 112, 114, 130 from the out put of generator 14 to an input 122, 124 of the buck amplifier 50 helps to stabilize the action of the regulating system. In an embodiment described with reference to Figs. 5A and 5B (not shown), the amplifiers 40 and 50 are constituted by magnetic amplifiers and the control circuit 70 includes a voltage sensing bridge circuit with reference Zener diodes. The theory of operation of the system is discussed in the Specification with reference to Figs. 2, 3 and 4 (not shown). Modifications include the provistion of a further impedance connected between the output of generator 14 and the series circuit 30, 12 (Fig. 6, not shown), and the provision of an auxiliary field winding for the generator 14 (Fig. 7, not shown).

[Class 106 (i)] The known size of a distant object, such as an aeroplane, is set by a knob 4, Fig. 7, the apparent size as measured on the graticule of a certain telescope is set by a knob 21 and the distance of the object is then given by the intersection of a line 62<a> with a scale 68. The angle of elevation of the object is then set by a knob 49, whereupon the line 62<a> moves to give, on the scale 68, the horizontal distance from the observer to the projection of the object, while the height of the object is given by the intersection of a line 2e with a scale 62. The knob 4 carries a pinion 11, Fig. 1, which moves a rack 13 linked to a lever 16 having a pin 18 which causes a plate 17 to slide up and down. A slider 28, Fig. 3, is moved along a slot 29 in the base plate by a cord 25 on a pulley 22 rotated by a knob 21. The slider is connected to a scalecarrier 34 having a slot 34a containing a slider 46 integral with another slider 44 running in a slot 17a of the plate 17. The sliders 44, 46 are fixed at right-angles and a further slider 43 is pivoted between them, this slider running in a slot 38b of a sector 38 pivoted at 37 and geared to an indicating dial 24 pivoted on the axis 20 of the knob 21. The carrier 34 is thus moved from left to right by turning the knob 21 until the apparent size is registered by the dial 24. The carrier 34 supports a scale 62 and a line 62a, Figs. 7 and 9, the line 62a now giving, on a fixed scale 68, the distance of the object. The angle of elevation is then set by adjusting the knob 49. This rotates a sector 55, Fig. 5, about a pivot 54 to swing a linkage 56, 59, 57. The scale 62 has two members 60 which slide in the linkage. The scale is thus unhooked from the carrier and so moved that the line 62<a> indicates the distance from the observer to the projection of the object while the scale 62 and fixed line 2e give the height of the object. The scale 62 can be initially adjusted for height above sea level by a pinion 64 and worm 65.
