Filed: 1941-02-07
Abstract: 547,042. Land torpedoes. WATSON, A. J. G. Feb. 7, 1941. No. 1691. [Classes 9 (ii), 92 (i) and 92 (ii)] Relates to pilotless self-propelled motor vehicles travelling on land and carrying a gun which is fired automatically during the travel of the vehicle. According to the invention, the gun is fired after a time determined by the distance travelled by the vehicle. The timing mechanism may also serve to control the firing of an additional explosive charge or the charge may be fired by impact. In the form shown, an armoured motor vehicle filled with endless .tracks 24 driven by a motor 26 is provided with adjustable guns 50 and an explosive charge 106 adapted to be fired in succession after a given travel of the vehicle. The time interval is determined by an endless band 56 driven from the vehicle wheels and carrying hooks 58 which engage a catch depending from a cord 92 connected with the gun trigger and the striking pin 116, Fig. 3, of a detonator for firing the charge. The catch is set in position by a handle 82. The explosive may be fired after delay caused by the action of acid on the container for the explosive, a bottle containing the acid being broken by a propeller device driven from the cord. An additional charge may be exploded on impact by a member 170. Specification 547,058 is referred to.

Filed: 1973-01-12
Abstract: 1453862 Load dependent braking GIRLING Ltd 27 Dec 1973 [12 Jan 1973] 1778/73 Heading F2F A control valve 10, for controlling pressure in a first circuit of a vehicle dual system, has a movable valve member subject to the action of a predetermined load and a load dependent upon vehicle loading, this load being removed from action on the valve by means responsive to pressure failure in the other circuit. The valve 10 is located in a rear brake line of a circuit supplying front and rear brakes, and has a ball 23 which blocks communication between the valve inlet and outlet but which is displaced to open such communication by a ring 24 carried by a member 11. Outlet pressure is a function of inlet pressure, of pressure of a spring 26, and of pressure of a spring 14 whose force is varied according to vehicle loading. If a pressure failure occurs in a second circuit, which supplies front brakes only, a piston 31 is an unloading device 12, previously held upwardly by fluid pressure, moves downwardly to move a lever 13 away from the member 11 to remove the vehicle loading effect on the valve outlet pressure so that rear wheel braking is not too great in the absence of front wheel braking.

Title: Improvements in engine mountings
IPC: G01L3/16
Filed: 1944-02-07
Abstract: 582,005. Determining dimensions of materials. DE HAVILLAND AIRCRAFT CO., Ltd., and BUCHER, J. B. Feb. 7, 1944, No. 2226. [Class 37] [Also in Groups XIX and XXXIII] A mounting for an engine driving counterrotating airscrews comprises resiliently-yielding means between at least one engine foot and its bearer, in combination with means consisting of rigid non-yielding members for restricting the range of the yielding movement to a small amount beyond which range the loads are transmitted without further yielding, and means for measuring the movement of the engine foot relative to the bearer, or a quantity which is a function of the movement, to measure the residual or differential torque transmitted to the engine bearers. In the form illustrated, Belleville washers 26 are provided between the engine foot 16 and bearer 20, the extent of movement of the washers being limited by the engagement with the bearer of rigid members 28 mounted on the foot. For the purpose of measuring the load on the bearer, and thus the residual torque, the members 28 support the edges of an electric strain gauge 36 of the type described, for example, in Specification 549,140, the lower surface of the diaphragm being engaged midway between the supports by a projection 38 carried by the bearer 20. According to a modification, Fig. 4 (not shown), two engine feet, one on either side of the engine, are each provided with two gauges, one of which is strained by downward movement of the foot and the other by upward movement thereof, the gauges being arranged in pairs as opposite arms of a Wheatstone bridge such that vertical movements of the engine do not affect the balance of the bridge, thereby eliminating the effect of engine oscillations in the vertical plane. According to the Provisional Specification the yielding movement of the engine foot may vary the width of an air gap in a variablereluctance magnetic circuit. Further, in the case of an engine with four feet, each one may be associated with an electric strain gauge, those on each side of the engine being connected in series to form an arm of a Wheatstone bridge, to eliminate the effect of vertical and pitching oscillations.

Apparatus for making a cam body consists of shaping devices 4, 5 operable to form a body blank having opposed hooked flanged edges about a mandrel 1 arranged to be expanded to interlock the hooked flanges and contracted immediately the hooked flanges are flattened by a hammer 8 against the mandrel 1 and a clamp 9 extending lengthwise of and movable relative to the mandrel 1 in such manner that the blank is lightly pressed against the mandrel 1 while being moved to the forming position, is clamped firmly against the mandrel 1 during forming until the hooked flanges are flattened by the hammer 8 and is released while the flattened hooked flanges are gripped between the mandrel 1 and the hammer 8. The clamp consists of articulated clamping elements 9, 9a carried by supporting members 10 having projections which engage with lost motion in inclined slots in actuating members 14. The light clamping pressure is derived from spring-loaded plungers 35. The heavy clamping pressure is derived from springs 16 acting on the actuating members 14 when a rod 13 is moved to one end position, and the clamping elements 9, 9a are lifted when the rod 13 is moved to the other end position, the actuating members 14 being moved by projections 17 on the rod 13.

Filed: 1946-01-24
Abstract: 631,377. Television receivers. WATTON, W. L. Jan. 24, 1946, No. 2331. [Class 40 (iii)] [Also in Group XL (c)] In a television receiver, interference pulses superimposed upon the picture signals and causing the signal to go beyond the normal range of picture signals are replaced by signals which vary in accordance with the average amplitude of the picture signals. First embodiment. The received signal 3 upon which is superimposed an interference pulse is applied to the control grid of the valve 6, which is adjusted, by means of the potentiometer 10 and the D.C. insertion circuit including the diode 8, to cut off at the level of maximum picture whiteness. Thus the signal applied to the valve 12 comprises interference pulses only. The signal 3 is also applied, through a delay network 16, to the valve 17, the purpose of the delay being to allow the output of valve 12 to straddle completely the interference pulse in the output of 17 so that the interference is reduced as shown at 18. The signal 18 is applied through an integrating network to the grid of cathode-follower 25, the output of which is consequently dependent on the average amplitude of the picture signals, since the interference has been largely removed by the valve 12. The output pulses from the valve 6 are also applied to valve 19 and thence to the anodes of the diodes 21, 22, which are normally cut off. During an interference pulse, however, they become conducting so that the output from the cathode-follower 25 is' applied to the cathode-ray tube in place of the signal 18. Second embodiment, Fig. 2 (not shown). The input signal, which is in this case inverted relative to the signal 3, is applied to an amplifier which limits just above the white -level to remove the greater portion of the interference. The amplifier output is applied to (a) a further amplifier and thence to the cathode-ray tube; (b) an integrating circuit; and (c) a further limiter which selects the interference pulses from the composite signal. The selected interference pulses are combined in a diode circuit with the integrator output, which modifies the pulse amplitude in accordance with the mean signal-amplitude, the signals then being applied to the cathode-ray .tube in parallel with the further amplifier to reduce the interference pulses to the mean-picture-signal level. Specification 470,140 is referred to. Reference has been directed by the Comptroller to Specification 470,140.
