Title: Improvements in fuzes for ammunition projectiles
IPC: F42C15/22
Filed: 1947-01-24
Abstract: 612,602. Projectile fuzes. MEFINA SOC. ANON. Jan. 24, 1947, No. 2253. Convention date, Feb. 1, 1946. Addition to 551,654. [Class 9 (i)] The invention of the parent Specification is now modified by surrounding the centrifugallyreleased weights 11 by a movable spring- actuated mass 20 which is held in position by means of a member 22 which only releases the mass as the result of the action of centrifugal force. In one construction the centrifugallycontrolled weights 11 are held in the safe position, that is in a position preventing movement of the striker 10 towards the detonator 18, by a sleeve 20 which itself is normally held in place by a spring ring 22. On discharge the ring 22 opens out under centrifugal force, thus permitting the sleeve to move forwards under the action of a spring 21 clear of the weights 11. The fuze mechanism then functions as in the parent Specification. In a modification, spiral slots in the sleeve co-operate with fixed pins to impart a rotary motion to the sleeve when it is moved by the spring 21, thus increasing the' time for releasing the weight 11. In a further modification, the sleeve has a rotary motion only, and has suitable apertures to permit outward passage of the weights when rotated by a spring to its operative position.

Abstract: 1,083,182. Electric analogue calculating. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Jan. 15, 1965 [Jan. 17, 1964], No. 2263/64. Heading G4G. An electrochemical integrator cell 1 of the kind in which the stored chemical charge is proportional to the integral of the input current and the output voltage is proportionate to the ionic concentration in the readout compartment of the cell and thus to the integral of the input current, has input terminals 2, 3 connected over a time constant resistor and a read out terminal 4 connected to a multistage transistor amplifier 5; the integrator being conventionally biased from circuit 1a. Output terminals 9, 10 of the final transistor stage 8 respectively develop an integrated output signal in the regard to earthed terminals 17 and 3 and energize the base of an emitter follower transistor 11 over potentiometer 12; the emitter of which is connected over a feedback loop to the base of the initial transistor stage 6, whose emitter is earthed over two silicon diodes 20, 21 and held negative to earth. The voltage drop across the base emitter circuit of stages 6, 7 holds the base potential of stage 6 and the voltage of terminal 4 negative referred to earth, and the readout current thereat is independent of small voltage changes and proportional to the variation in charge of the cell. By variation of potentiometer 12, the bias over the feedback loop is adjusted so that the amplifier output is zero at a datum level of the cell input current and varies thereabout with the integral of the input signal. The cell is enclosed in a temperature stabilized enclosure, or temperature compensated by giving feedback resistance 14 a negative temperature coefficient of resistivity. A more sophisticated circuit is described and illustrated in the Complete Specification. The apparatus is applicable to the integrating control of a servomotor system.

Abstract: 640,911. Weighing-apparatus. AVERY, Ltd., W. & T. (Williams, L. S.). Jan. 25, 1947, No. 2366. [Class 143] In a weighing scale employing hydraulic force transmitting elements incorporating a hydraulic capsule for supporting a portion of a load receiver and connected hydraulically to a bellows for transmitting the force to a load counterbalancing mechanism, a resilient element is interposed in the force transmitting system for supporting a predetermined but variable proportion of the load. The load receiver 1, Fig. 1, is supported on hydraulic capsules 6. communicating through pipes 15 with a series of pressure receiving elements 16 which convert hydraulic pressure into mechanical force and transmit it through a rod 20, a gathering lever 21, a stirrup 26 and a rod 27 to one side of a counterbalancing steelyard 30. To correct for variations in force transmission ratio due to the bellows of the receivers 16, the lever ratio of the gathering lever 21 is adjusted to give accurate scale indications at zero and half load whilst to give a correction between half and full loads a spring 35, Fig. II, is secured to the stirrup 26 and is adjustably secured to the lower end of the rod 27 by nuts 37 which, together with a screw 36, enable the spring 35 to be pre-stressed so that force is absorbed in further stressing said spring only after the load receiver is supporting more than half load. In the embodiment shewn in Fig. III the externally stressed bellows 39 of each receiving element 16 is supported on an annular diaphragm 47 which undergoes a greater deflection during the first portion of the weighing range than it does during the second so equalizing the transmission ratio throughout the complete weighing range. In the embodiment shewn in Fig. V a pair of cone spring washers 60 are interposed between a tenoned member 57, fast with the bellows cap 52 and a flat washer 61 at the top of a hole in the force transmitting rod 53 in which hole the tenon of the member 57 can slide. A sleeve 62 is welded to said tenon after pre-stressing of the cone washers which can then be further stressed only during the second half of the weighing range. In the embodiment shewn in Fig. VII a spring 76 secured to a fixed part of the scale is contacted by a member 75, fast with the force transmitting rod 69, during the second half of the weighing range. In a further embodiment (not shewn) fluid is bled from the pipes connecting each capsule and bellows during the second half of the weighing range by means of a closed ended rubber tube partly contained in a rigid tube which only allows the exposed portions of the pipes to expand. The last embodiment, together with those shewn in Figs. III, V and VII give full connection even if the load is not centrally placed on the platform since in each case the resilient elements operate between the capsules and. the gathering lever 21.
