Title: Electrical projectile fuse with switch means
IPC: F42C15/40
Filed: 1973-10-23
Abstract: 1389360 Projectile fuzes DIEHL 23 Oct 1973 [13 Nov 1972] 49170/73 Heading F3A An electrical fuze for a projectile comprises a piezoelectric element 9, Fig. 1, which is activated on target impact or after a predetermined flight duration and triggers an electronic switch, e.g. a thyristor, to enable a capacitor to discharge through an armed electrical igniter 39. A spring-loaded striker 14 is provided to activate the piezoelectric element 9 after the predetermined flight duration. The striker is normally held in a retracted position by two pivoted, inter-engaging pincer arms 45, 46, Fig. 2. An articulated part 49 of the arm 45 is urged radially inwardly by a leaf-spring 56. However, its hooked end 53 is prevented from disengaging the hooked end of the arm 52 by the interposition of a cylinder 55. Centrifugal force causes the part 49 to move radially outwardly against the action of the spring 56 thereby releasing the cylinder 55 and enabling the hooked ends of the pincer arms to move into closer engagement. As the centrifugal force decreases, the part 49 is moved radially inwardly by the spring 56 until the hooked ends of the pincer arms become disengaged. Thereupon, the arms move outwardly under the action of the residual centrifugal force to release the striker. The centrifugal force also expands a spiral band 30, Fig. 1. This releases an electrical contact 27 which is moved by a spring 25 into abutment with a contact 40 of the igniter 39 that, meanwhile, has been moved into the armed position by a centrifugal rotor 38. The igniter is short-circuited in the unarmed position by engagement of the contact 40 with the fuze body 1. The capacitor for supplying current to the igniter is charged upon firing the projectile by an electromagnetic generator carried by the fuze; or by a piezoelectric element 20 which is compressed by an inertia plate 19; or alternatively is charged before firing by an external source of electrical energy.

Abstract: 1376408 Recording apparatus UNITED STATES ATOMIC ENERGY COMMISSION 30 Oct 1972 [9 Nov 1971] 49916/72 Heading G1J [Also in Division G4]  An analogue data recording apparatus compares a repeating train of analogue pulses with a varying reference to provide a signal each time one of the pulses exceeds the reference, each such signal being gated to an output corresponding to the position in its train of the originating analogue pulse, each output marking a moving record medium when the first signal occurs on that output so that the position of the mark corresponds to the amplitude of the analogue pulse. As disclosed, in a photo-metric analyzer, the transmittances of 16 samples in a rotor 7 are sensed in turn by a photo-multiplier 27 repeatedly, slots 13, 15 being sensed by photo-detectors 23, 25 to increment and reset respectively a binary counter 47 to identify the sample currently being sensed. The sample values from photo-multiplier 27, after biasing at 31, are compared at 35 with a varying reference from a potentiometer 37. When a value exceeds the reference a pulse from 35 sets one of 16 flip-flops 41 selected by the counter 47 decoded at 49. When such a flip-flop is first set a corresponding one-shot 53 actuates a corresponding pen driver 55 to mark a card 59. The pens are carried up the card on a carriage 57 actuating limit switches 69, 71 to control its own movement, and the reference potentiometer 37 is driven to provide a decreasing reference in sync with this movement so the height of the mark on the card in a given channel indicates the pulse amplitude from the corresponding sample. A potentiometer 38 is used for calibration against e.g. a water sample. The reference potentiometer 37 may be linear or logarithmic, the recorded output representing concentration in the latter case.
