IPC: H03K3/037
Filed: 1965-08-19
Abstract: 1,148,317. Gating circuits. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. 19 July, 1966 [19 Aug., 1965], No. 35698/65. Heading H3T. In a direct-current toggle circuit employing a plurality of NAND or NOR gating elements E1, E2, E3, E4, gates E2 and E3 are arranged to form a bi-stable circuit and with similar inputs C, D applied at the same time to the gate E1, which has two inputs only, the gates E1, E2 and E3 are switched without switching the gate E4 and hence the output of the toggle but on removal of the input signal on one only of the inputs C, D the gate E1 returns to its initial state and causes switching of the gate E4 and hence the output of the toggle. Removal of the " 1 " input on C and/or D causes the toggle to return to its initial state. The gates E2 and E3 remain in their switched state until a RESET pulse is applied at R which changes gates E2, E3 and E4 back to their initial states and also changes the output. The gates may be diode AND gates followed by a PNP common emitter transistor inverter. The output from the circuit is fed to an inverter E5 which may be a PNP common emitter transistor. Data processing.-In a data processing system including a data highway for the transmission of address information and data information in a time sharing manner between one of a number of peripheral devices and a central data processing device a D.C. toggle circuit as described above can be associated with each peripheral device. A particular peripheral device is selected by connecting the address signifying that device to the highway; this opens the address gate of that peripheral device and changes the input on D to a " 1 " state. When an address data control signal produced by a computer is applied to the input on C the gates E1, E2 and E3 are switched. At the end of a particular time the address gate is closed, and this causes the signal on D to return to its initial " 0 " state. This switches gates E1 and E4 to change the state of the toggle output. The output is used to prime highway fed gates of the peripheral device so as to allow the next set of data to be gated into the peripheral device or data to be presented to the central control.

Title: Improvements in or relating to a percussion fuze for projectiles
IPC: F42C15/285
Filed: 1937-12-28
Abstract: 490,196. Projectile fuzes. SAGEB SOC. ANON. DE GESTION ET D'EXPLOITATION DE BREVETS. Dec. 28, 1937, No. 35873. Convention date, Dec. 31, 1936. [Class 9 (i)] Relates to projectile fuzes of the type in which the striker and primer are held apart by one or more balls or the like, which are in a state of unstable equilibrium, and which are held in the safety position by retaining means until the projectile is in flight. According to the invention, the retaining means comprises a dashpot piston which is normally held in in the safety position by members held in engagement therewith by a spring- controlled ring, the spring of which also serves to drive the dashpot piston. In the construction shown, the striker 3 is urged towards the primer 4 by a spring 5 which is compressed between the striker and a socket 7. The striker is normally held in the retracted position by balls 8 which are held in the operative position by a spring-urged socket 9. This socket is retained in position by one or more balls 11 arranged between the socket and a fixed abutment 14. A plunger 16 is slidably mounted in the body 1 of the fuze and is under the action of a compression spring 20. The plunger is normally retained in the retracted position by a number of balls 17 which are mounted in recesses of the plunger and bear against one of the balls 11. The balls 17 are held in place by a ring or sleeve 19 against which the spring 20 bears. In operation, the sleeve 19 sets back by inertia during the accelerating movement of the projectile, thus compressing the spring 20 and freeing the balls 17 which move outwardly. During flight, the sleeve is urged forwards and bears against the plunger which then moves forwards slowly, the movement being retarded by the air trapped in the space 23. In its forward position, the plunger is clear of the balls 11. On impact, the balls 11 are scattered, thus freeing the socket 9 which is urged forwardly by its spring to release the balls 8. Due to the shape of the groove in the striker, the balls 8 are urged outwardly by the striker when the latter is moved by its spring to ignite the primer. In a modification, the spring 5 bears directly on the socket 9, the separate spring 10 shown being omitted, and in another modification the positions of the striker and primer are reversed.
