Title: Supply circuit for a gas discharge character display tube
IPC: H03K21/08
Filed: 1972-01-26
Abstract: 1381167 Automatic current control PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 Jan 1972 [29 Jan 1971] 3625/72 Heading G3R [Also in Division H2] A gas discharge tube used for display of characters comprises at least one anode and a plurality of cathodes in the form of characters, at least one of the cathodes being arranged to luminesce for all the characters to be displayed the circuit of which cathode comprises a resistor across which a control voltage is developed and which serves as the input signal to a constant current source whereby the current flowing in the resistor, and hence the cathode circuit is maintained constant. A gas discharge tube 1 comprises three anodes 3, 5, 7 each anode being associated with four cathodes 9-15, the corresponding cathodes being connected in parallel and each group having a resistor 27 or 29 or 31 or 33 connected in series therewith. The supply for the anodes 3, 5, 7 is derived from a constant current source 22 by way of respective transistors 17, 19, 21 control of which is effected by a so-called decoder 23. Cathodes 11, 15 are arranged to luminesce for all the characters displayed and the voltages developed across resistors 29, 33 and fed to the base of a transistor 51 in the current source 22 by way of diode gate 45, 47. The difference between the base voltage and the emitter voltage set by a Zener diode 53 determines the base and collector currents of transistor 51 and these determine the output voltage of a converter constituted by a transformer 57 and a transistor 61, the output voltage of which is rectified by a diode 63 for application to the anodes 3, 5, 7. Thus the output voltage of the source 22 is maintained constant at a value determined by the Zener diode 53 and hence the current in the cathode circuits of the tube are also kept constant. Luminescing of the cathodes 9-15 is terminated by transistors 37-43 being made conductive by way of the decoder 23.

Title: Improvements in or relating to Means for Carrying and Dropping Depth Charges.
Inventor: BROOKS THOMAS
IPC: F42B21/00
Filed: 1918-03-01
Abstract: 123,598. Brooks, T. March 1, 1918. Torpedoes, locomotive.-Consists in arranging depth charges on torpedoes, or like bodies propelled by internal power or imparted momentum, in such a manner that the depth charges are released after a given time. In the form shown assembled in Fig. 3 and separated and in a plane at right-angles to Fig. 3 in Fig. 5, a depth charge a takes the place of the usual war head of a torpedo, the rear part c being as usual. The parts a, c are secured together by a central stem e on the part a fitting into a socket g on the part c and locked therein by a transverse wedge or bolt f, a conical joint d, d<2> being held water-tight by the wedging action of the bolt f. This bolt is expelled at a given moment by a cartridge h fired by a time fuse; at the same time, spring plungers i, j push the depth charge a away from the rear part c. Screw-plugged holes x<2>, x<3> give access to the fastening device. The nose of the depth charge is provided with a contact firing device as usual in torpedoes, and its base with a soluble plug for explosion at a given depth after release as usual in depth charges. The depthcharge may be carried by an ordinary torpedo, in addition to the charge which is exploded on impact in the usual way. Specification 14622/84 is referred to. The Provisional Specification states also that the motor of the depth-charge carrier may be driven by energy, e.g. electricity, supplied from a distance: or by means of wires coiled on drums in the carrier and operated from the shore : or may be operated or controlled by wireless means. Modifications in the arrangement and form of the depth charge are described. It is further stated that the steering-apparatus of the carrier may be automatically operated on the release of the depth-charge so that the carrier returns towards it starting-place.

Title: Improvements in or relating to electric indicating systems for radio direction finding
IPC: G01S1/02
Filed: 1939-02-03
Abstract: 524,701. Directive wireless systems. LORENZ AKT.-GES., C. Feb. 3, 1939, No. 3661. Convention date, Feb. 4, 1938. [Class 40 (v)] Relates to systems for restoring to normal position an electric indicating device cooperating with a receiver for determining bearings relative to a transmitter and more particularly to such indicating devices when combined with the D.F. system described in Specification 447,707 in which the number of dot and dash signals received from a rotating beacon is counted from a zero time. According to the invention the receiver is provided with a first relay which responds to received signals and this relay energizes a second relay forming part of a local circuit which second relay causes the indicating device to be restored to normal position. In the Figure, part of the receiver output is applied to the relay A through the amplifier R, the grid circuit K of which is tuned either to the modulation frequency or, in the case of C.W. transmissions, to the frequency of the locally-generated oscillations. Just prior to a signal transmission period, the transmitter is switched on, resulting in the response of the relay A which energizes relay B through its contact al and the normally-closed contact c of relay C. Operation of relay B energizes the electromagnet M which restores the indicator Z to its normal position. In a simplified circuit, the winding of the relay B constitutes the electromagnet M. When the indicator is restored to normal, relay B is de-energized by relay C, which is energized first through a second contact b2 of relay B and is then maintained energized through its own contact c as long as signals are being received. During the gap in the signal transmission, the indicator Z is disconnected from the receiver by a second contact a2 of relay A, and it is illuminated by a lamp also operated by the relay system. The call sign of the transmitter is radiated during this period and is of a different wave or modulation frequency so as not to affect the relay A.

Title: Improvements in or relating to friction clutches
IPC: F16D43/12
Filed: 1937-02-08
Abstract: 489,780. Friction clutches. BORG & BECK CO., Ltd., and HIGGS, C. W. Feb. 8, 1937, No. 3709. [Class 80 (ii)] In a plate clutch wherein the engaging pressure is provided wholly or in part by centrifugal elements, the latter comprise levers 12 which are pivoted at their inner ends on lugs 13 extending from a common ring 14 secured to the inner rim of the cover plate 1, so as to swing in planes radiating from the clutch axis, which are weighted at their outer ends, and which transmit the centrifugally-induced engaging pressure to the pressure plate 4 through springs from an intermediate point of the levers. In the semi-centrifugal clutch shown in Fig. 2, engaging pressure is provided partly by springs (not shown) disposed between the plates 1 and 4, and partly by the levers 12. Each of the latter has secured thereto a round-nosed pin 25 engaging a recess in a member 27 between which and the plate 4 a spring 28 is arranged. The levers 12 project through slots 18 in the plate 1, the ends of the slots limiting the movement of the levers. Disengagement is effected by radial levers 33 controlled by a sleeve 35. In a modification, the lever 12, Fig. 4, has a recess engaged by the rounded end of the boss 37 of a cup 38, a spring 41 being arranged between the cup and an annular recess in the plate 4 containing a washer 43 of low heat-conductivity. The cup 38 telescopes over a pin 44 secured to the plate 4, the arrangement being such that the cup 38 abuts against a collar 47 on the pin when the spring has been compressed to a certain extent. Thus centrifugally-induced pressure is applied first through the spring and then directly. In a wholly-centrifugal clutch, the extension of the spring, through which engaging pressure is applied, is limited. As shown in Fig. 6, the spring 76 is disposed between the weighted end 62 of the lever 12 and the head 75 of a stem 73 slidable through the end 62, extension of the spring being limited by a nut 77 on the stem 73. A recess in the head 75 is engaged by the rounded boss 80 of a star-shaped spring 81 bearing on the plate 4. Manual disengagement can be effected through radial levers 84. Springs 83 acting on these levers tend to move the plate 4 to disengaged position. In a modification, a spring 97, Fig. 7, is interposed between thimbles 95 and 98, the thimble 98 abutting against the plate 4 while the thimble 95 abuts against a pin 93 secured to the lever 12. Extension of the spring is limited by the engagement of flanges 96 and 102 on the thimbles. According to the Provisional Specification, the centrifugal levers may transmit the pressure directly to the pressure plate, and the levers 12 may be pivoted on brackets secured independently to the cover 1.
