Title: Impact fuse for an explosive spin projectile
IPC: F42C1/06
Filed: 1973-08-14
Abstract: 1412058 Projectile fuzes DIEHL 14 Aug 1973 [14 Sept 1972] 38346/73 Heading F3A A projectile fuze, responsive to direct and oblique angles of impact, comprises a primer 15 which is fired either by an axially displaceable striker (3, Fig. 1, not shown) on direct impact or by inwardly directed spikes 17 of a ring 5 when the ring is caused to more laterally by an oblique impact of the fuze. The lateral movement of the ring is assisted by centrifugal force in a spinning projectile. The ring 5 is locked against lateral displacement until the projectile is fired by an inertia member 6 which moves axially out of the middle of the ring into the aimed position (shown),where it is retained by a springwire 11. Inadvertent displacement of the unlocked ring by impact of the fuse with foliage etc. is prevented by spring loaded cams 19 which are readily overcome by the greater impact forces. The gases from the ignited primer 15 throw a striker 16 against a detonator (not shown) for the main explosive charge of the projectile.

Title: Display systems
IPC: G09G3/20
Filed: 1973-08-15
Abstract: 1458045 Matrix displays and circuits therefor DEFENCE SECRETARY OF STATE FOR 13 Sept 1974 [15 Aug 1973] 38635/73 Heading G5C A panel display system providing a refresh operation using the panel as its own memory includes a plurality of display elements 3 11 , 3 21  ... 3 n1 ; a plurality of electrical gates 11 each connected to a column of elements, a plurality of sensors 15 in a feedback loop 13 extending between the column of elements and the gate, the sensors detecting directly or indirectly a property of an element in order to determine whether the element is on or off. One system comprises liquid crystal elements 3 at the intersections of X, Y conductors. Energizing pulses are applied via gates 11 from a source 9 whilst pulses are applied sequentially to the X conductors. The potential on each Y conductor is measured by a comparator 15 which can operate a monostable circuit 19 connected to a corresponding gate. The elements have an increased capacitance when energized. This is detected by applying interrogation pulses to each X conductor successively. The potential generated on each Y conductor depends on the state of the respective element and is sensed by a comparator 15. These open gates 11 and apply further energizing pulses only if the respective element was in the on state. A coincident pulse is applied to the X conductors. Write pulses are applied by a reset circuit 21 either to gates 11 or to sources 17 to alter the reference voltage momentarily thereby causing the comparator to alter the state of an element. Alternatively Fig. 3 (not shown) photosensitive elements are located adjacent electroluminescent display elements and are connected between the X conductors and Z conductors arranged parallel to the Y array. The feedback circuits are connected to the Z conductors and sense changes in resistance of the photosensitive elements. The display elements may be L.E.D's, gas discharge lamps, electrochromic or electrophoretic elements; changes in stored charge may be measured.
