Title: Mounting for automatic firearm with elevating gear compensator
IPC: F41A27/30
Filed: 1944-10-03
Abstract: 586,981. Gun mountings. LIPPERT, H:, and ENGELER, G. Oct. 3, 1944, No. 18948. [Class 92 (i)] An automatic firearm 3, Fig. 1, on a mounting 1 and having an elevating gear compensating device, such as a spring 11 engaging with a member 10 connected as shown to the cradle 2, is provided with a braking device which prevents movement of the cradle under the action of the compensating device when the firearm is removed from its cradle. As shown in Fig. 2, the elevation and depression of the gun is effected by a shaft .7 having a worm 6 which engages with a wheel 5 geared to the cradle. Normally, the axial thrust on the shaft is to the left and is transmitted to the mounting by a bearing 16 which is urged against a collar 13 on the mounting. On removing the firearm, the compensating device will tend to rotate the cradle in a clockwise direction, thus urging shaft 7 to the right. This force is transmitted by a shoulder 12 on the shaft to an inner ring of a bearing 14, and thence via a bush 15 and bearing 16 to a conical member 17 keyed to the shaft. The member 17 is thus pressed against a fixed ring 20 having an internal bore corresponding to the shape of member 17 and thereby prevents the shaft 7 and consequently the cradle from rotation under the action of the compensating device. In a modification, Fig. 6, the firearm 3 normally engages with a roller on a lever system 26 mounted on the cradle. On removing the firearm, the system moves under the action of a spring 28 and rotates a segment 29, a nose 30 on the segment thereby being moved clear of a spring-pressed roller 33. The roller is now urged by its spring' to the right and becomes clamped between the mounting 1 and the body 31 which is keyed to the cradle, thus locking the cradle against rotation. In another modification, Figs. 7 and 8 (not shown), a similar lever system when rocked upon removal of the firearm moves clear of a lever which is then free to move under the action of a spring, the lever being mounted on a screw-threaded member on the cradle, so that when it rotates it also moves axially and clamps the cradle to the trunnion.

Title: Improvements in or relating to clock oscillator arrangements
Inventor: GRAHAM COLIN
IPC: G06F11/16
Filed: 1969-04-14
Abstract: 1,263,276. Automatic phase control; logic circuits. MARCONI CO. Ltd. 6 April, 1970 [14 April, 1969], No. 19089/69. Headings H3A and H3P. A clock oscillator arrangement includes at least three oscillators M1, M2, M3, one of which is a master and the others slave units, and it is arranged that upon the occurrence of a phase fault between the master and one of the slave units, one of the other slave units is made the master. The frequency of each oscillator is controlled by a varactor diode in response to the integrated output of an OR or an EXCLUSIVE OR gate, the inputs to which are the oscillator output and a reference pulse signal delayed 90 degrees (Figs. 2, 3, not shown); thus the frequency and phase of each oscillator is synchronized with its reference source, either the oscillator designated the master or in the case of the master itself, an external source T. The output of the integrator is also applied to a Schmitt trigger which produces an output if the phase difference between the associated oscillator and its reference exceeds a predetermined amount. This output is applied to a logic circuit (Fig. 4, not shown) wherein pairs of NAND gates, cross-connected as bi-stable devices (37 ... 42) which control gates 1G1 etc., are switched over in such a way that the external reference pulses T are switched to control the third oscillator, making that the master. For example, if M1 is initially the master, an excessive phase error between M1 and M3 causes gate 1G1 to close and 2G1 to open, making M2 the master and M1 a slave. The logic circuit includes gates which prevent a further change of master until reset. This circuit also operates warning lamps which indicate the faulty oscillator unit.

Abstract: 141,770. Imperial Trust for Encouragement of Scientific & Industrial Research, Sears, J. E., and Brookes, A. J. C., Nov. 22, 1918. Drawings to Specification. Block, rubber, and like apparatus; processes, special.- A method of producing gauge slips or blocks consists in lapping or grinding a number of gauges simultaneously and interchanging the position of such gauges between successive lappings. A number of gauge-blanks of the same nominal size and thickness, and each having one face approximately plane, are placed with their plane faces next the facet upon coplanar facets in a chuck described in Specification 142,024, and are ground by rubbing them upon a flat metal surface charged with finely ground abrasive. After lapping, the gauges will be truly flat on one side, but may be of different thicknesses owing to the ground faces being in a plane slightly inclined to the plane in which lie their opposite faces. Some or all the gauges are then interchanged and turned end to end upon a definite plan having regard to their mean thicknesses, and again lapped simultaneously. Preferably, the whole of the gauges are turned over and their opposite faces dealt with at the second lapping. Magnetic adhesion between the slips and facets may be provided.

Filed: 1947-07-18
Abstract: 657,675. Radiolocation. BRITISH THOMSON-HOUSTON CO., Ltd. July 18, 1947, No. 19342. Convention date, July 21, 1943. [Class 40 (vii)] In a pulse radar system, comprising means for enabling the presence of echo signals, which on a visual display are obscured by noise, tobe detected, the received signals are applied to two channels which are sequentially gated by adjacent gate-pulses applied thereto during each pulse-cycle, and the channel outputs are integrated and applied to a differential indicator which, when an unbalanced output is obtained, indicates the presence of an echo signal during one or other of the gating intervals. The radar system comprises a transmitting aerial 1 and a receiving aerial 4 mounted upon a common rotatable shaft 2 and connected respectively to transmitter 3 and receiver 5. The output of the receiver 5 is applied to the grid of cathode-ray tube 7 comprising a deflect. ing-yoke 8 which is coupled to the shaft 2 for rotation with the aerials 1 and 4. The aerials may rotate continuously producing a normal P.P.I. display or they may oscillate over a limited arc, so producing a sector display. The output of receiver 5 is also applied through buffer amplifier 10 to two channels 11 and 12, Fig. 2, to which gating pulses are sequentially applied from gate circuits 14 and 15, respectively. Pulses from the transmitter 3 are applied to the delay circuit 16 comprising a multivibrator which after a predetermined adjustable interval applies a positive pulse to the gate-circuit 14 comprising a further multivibrator. Gate-circuit 14 similarly applies a positive pulse to gate-circuit 15, also a multivibrator, after a predetermined interval. Positive pulses from circuits 14 and 15 are applied to channels 11 and 12, comprising a pair of valves arranged in push-pull, to allow the sequential passage of echo signals therethrough to integrating condenser 13. Noise signals received during the two gating intervals approximate to the same value and hence produce little or no effect upon voltmeter 17 connected across the condenser 13, while an echo signal produces a greater charge on one plate than the other, this producing an indica. tion at 17. Voltmeter 17 may control an alarm 18 to indicate the presence of an echo. The range of the echo-producing object may be determined by varying the delay introduced by circuit 16 to determine the setting at which the sign of the voltmeter deflection changes,
