Filed: 1924-10-07
Abstract: 245,506. Armstrong, Whitworth, & Co., Ltd., Sir W. G., and Morrison, R. Oct. 7, 1924. Sights and methods of sighting.-A directorsight of the kind described in Specification, 212,980 is provided with an equalizing gear to correct the range transmission so that equal divisions on the range scale correspond to unequal movements of gun elevation. In the apparatus shown, the range transmission is effected by a " follow-the-pointer " device controlled by a hand-wheel 3 which operates through an epicyclic equalizing-gear on a pinion 20 driving the planetary pinions 22 of a differential gear, the sun-wheel 23 of which drives the transmitting switch 35. The other sun-wheel 23<1> is rotated when a handwheel 24 is operated to elevate the director-sight 33 to follow the target. The switch 35 therefore receives the sum or difference of the movements imparted by the hand-wheels 3, 24. The epicyclic equalizing gear interposed between the shaft 9 of the " follow-the -pointer " device and the pinion 20 includes a disc 10 which is fast with the shaft 9 and carries planetary pinions 12. These pinions engage a fixed wheel 13 and a moving wheel 14, the latter being thereby driven faster than the disc 10. Engaging with special cam slots in the disc 10 and wheel 14 is a pin 16 which carries a block 17 engaging a slot 18 in the toothed wheel 19 driving the pinion 20.

Title: Electronic adjustable time-delay devices
IPC: H03K17/292
Filed: 1975-06-05
Abstract: 1507514 Time delay circuit FRANCE ARMED FORCES MINISTER OF 5 June 1975 [5 June 1974] 24331/75 Heading H3T In a time delay circuit of the type which produces a pulse a predetermined time after a switch is closed, either the anode potential of a PUT is held at a first reference level and the gate potential is allowed to fall from a second reference level at a fixed rate until it just falls below the anode potential, whereupon the PUT conducts, or the gate potential is held constant and the anode potential allowed to rise until it just exceeds the gate potential. As described, in a first embodiment, Fig. 1, the delay circuit is put into its ready state by connecting a power source S as shown and putting switches G1, G2, G3 into their first position. This causes a first capacitor C1 to be charged to a first reference potential set by a zener Z, and a second capacitor C2 to be charged to a second reference level equal to the potential of the source S. The source S may now be disconnected, and in the envisaged use of the circuit in a military projectile, is, in fact disconnected. Some short time later, the delay is actuated by putting switches G1, G2, G3 into their second position. Capacitor C2 then discharges via a resistance Rd and eventually the PUT becomes conductive thereby producing a positive output pulse on its cathode. This pulse fires a thyratron Th, the energy for which comes from a capacitor C3 which was also charged when the switches G1, G2, G3 were in their first positions. When the circuit is used as envisaged, the additional components R2, C4 may be included, thereby preventing a very large current passing through the thyratron Th, and its load A, unless a minimum period elapses after the switches G 1, G2, G3 are put into their second position, and before the PUT becomes conductive. In the second embodiment (Fig. 2, not shown) the gate potential is maintained constant (C2, Z) and the anode potential is caused to rise by charging a capacitor (Cl) via a resistor (Rd) from a large precharged capacitor (C5).
