Title: Improvements in Fuzes for Projectiles.
Inventor: KENNEDY DAVID
IPC: F42C1/06
Filed: 1918-02-25
Abstract: 130,629. Kennedy, D. Feb. 25, 1918. Projectile fuses.-Relates to percussion fuses provided, with a transverse safety-bolt normally retained by a member which is released from its operative position by set-back on discharge. According to the invention, the retainer is in the form of a hinged plate adapted to set back into a position in which it is free to swing outwards and thereby arm the fuse. In the construction shown, in which a safety-bolt B is, as usual, provided with an ejecting-spring C, the retainer for the bolt is a plate F, shown separately in Fig. 4, having flanges G with slots G<1> through which passes a pivot-pin E. This pin is fixed between cheeks D<1> on a sleeve D surrounding the fuse-body A. Tongues F<1> on the retainer are adapted to engage behind inturned edges D<2> of the cheeks D<1>, so that in the position shown, the plate F is prevented from swinging outwards. An outer shutter H is also pivoted on the pin E, and has flanges with which an ordinary safety-pin L, passing through the cheeks D<1>, engages during transit. The tongues F<1> on the retainer may be long enough to engage also in slots in the flanges of the outer shutter. On discharge of the projectile from a gun, the safety-pin L having been previously removed, the retainer F sets back, so that the tongues F<1> move clear of the edges D<2>, and the parts F, H are then free to swing outwards about their pivot E and allow the safety-bolt B to escape. Preferably, the parts are so arranged that the full outward movement of the retainer cannot take place until the projectile is out of the gun. The fuse comprises a known combination of a movable detonator-holder Q with a movable striker member N<1> and an inertia ball 0, and has, in addition, a cup-shaped guide R for the striker-pin and a ring F within the guide extending to meet the part N<1>.

Abstract: 1298451 Generating random pulses NETHERLANDS APPLIED SCIENTIFIC RESEARCH FOR STATE DEFENCE 31 Jan 1962 [2 Feb 1961] 3773/62 Heading H3P A generator for producing a quasi random series of pulses which can have only two values, the number of pulses of one value being a desired fraction of the number of pulses generated, comprises a periodic pulse generator and a gate circuit controlled by a noise generator and by a control voltage which governs the threshold level of the gate; the control voltage being obtained by counting the pulses appearing at the output of the gate circuit in a counter, diminishing the counter number by a fraction of the pulses generated by the periodic pulse generator, this fraction being the desired probability of occurrence of a pulse at the output of the gate circuit, and converting the contents of the counter into a numerical signal from which the control voltage is derived by means of suitable filters. In the drawing pulses from a periodic pulse generator 1 are fed to a gate circuit 2, the output of which is fed to an output terminal 10 and also in an additive sense to a counter 3. Pulses from generator 1 also pass to a divider circuit 5, which divides the pulses by a factor equal to the required probability that pulses shall appear at the output 10, and the output of divider 5 is fed in a subtractive sense to the counter 3. The counter 3 may be a binary counter, and its most significant digits (e.g. five out of a total of ten) are passed to a binarynumerical converter 7. The output of unit 7 passes through a low-pass filter 8 to an adder circuit 9 to which the output of a noise generator 4 is also supplied. The output of unit 9 passes to an amplifier 6 designed so that a small variation of its input changes its output from a fixed high value to a fixed low value or vice versa, and the amplifier 6 controls the gate circuit 2. Means may be provided for preventing the counter 3 passing from its maximum to its minimum by the addition of a pulse, or from its minimum to its maximum by subtraction of a pulse; these means may comprise diodes arranged to prevent the passage of addition pulses when the counter is at its maximum and to prevent the passage of subtraction pulses when the counter is at its minimum. In an alternative arrangement pulses from the unit 1 pass alternately to the gate circuit 2 and to the divider 5, and the pulses from unit 1 are used to switch the counter 3 alternately from an adding to a subtracting condition and vice-versa.

Title: Improved logical shifting devices
IPC: G06F5/01
Filed: 1969-01-23
Abstract: 1,254,722. Shift circuit. NORTHERN ELECTRIC CO. Ltd. 23 Jan., 1969 [31 Jan., 1968], No. 3786/69. Heading G4C. Shift circuit has a plurality of logical units at two or more different levels, one unit at each level being controlled to pass a word to be shifted through said one unit at each level such that the total time taken by a shifting operation is constant for all such shifting operations. A word of, for example, 16 bits is applied on line 8 to one of three logical units each unit containing a plurality of NAND gates. Unit 5 causes left shift of the word by 8 places. Unit 6 causes no shift and Unit 7 causes right shift of the word by 8 places. Each unit is coupled to three units on a second level causing respectively left shift by 4 places, no shift and right shift by 4 places. Each of these units feeds three units causing respectively left shift by 2 places, no shift and right shift by 2 places. A final level contains units causing left shift by one place, no shift, right shift by one place. Thus the circuit can cause any left or right shift by up to fifteen places. The NAND gates in the units are enabled by signals on control lines 28-39 to cause the appropriate unit to pass the signals. For left and right shifts in which data removed from one end is replaced by zeros entered in the other end of the word a full 16 NAND gates are not required in all units. Units 6, 13, 16, 19 require all 16 gates. Units 18, 20 require 16 gates but one gate in each unit need have the control line 37 or 39 respectively as the only input to one gate since the appropriate shift will leave one output zero and a " 1 " control signal to that gate will produce a zero output. Units 15, 17 need have only 14 gates each receiving two inputs, a control signal and a signal from a prior unit. Units 12, 14 have 16 gates each but 4 in each unit have the control signals as the only inputs, and units 5, 7 have each only 8 two input NAND gates. End around shifting circuits require 16 two input NAND gates in each unit. The units can be integrated circuits and are suitable for use in digital computer arithmetic circuits or in telephone switching circuits.
