[Also in Division H4] Connector for connecting a detonator 20 to a detonating fuse-cord 19 in a method of marine seismographic prospecting wherein a length of fuze-cord is unwound from a drum and trailed behind a boat comprises, a body 10, e.g., of polyethylene, formed with two substantially parallel intercommunicating bores 12 and 13 into which the detonator and fuze-cord are slidably inserted and held in such proximity to each other that detonation of the detonator causes detonation of the fuze-cord, and one or more metal tie rods 17 each attached by one of its ends to the body for joining the connector to an electric firing cable. The end of the fuzecord is covered by a metal cap and is doubled back into a third bore 14 containing waterproofing composition. The electric lead wires of the detonator are secured in slots 16, and the bared end 23 of one lead is allowed to trail in the sea or soldered to a metal sleeve surrounding the body so as to provide an " earth." The bared end 22 of the other wire is in electrical contact with the tie-rod 17, which terminates in a split-ring 18. A slip-ring 24 enables the assembly to be slid down the cable 21. In other embodiments, the tie-rod terminates directly in a slip-ring or in a hook engageable with a slip-ring. Alternatively, two tie-rods can be used which hook together to form a slip-ring, the ring being broken as the fuze-cord explodes and destroys the body 10.

Abstract: 1391636 Testing circuit isolation LICENTIA PATENT-VERWALTUNGS-GmbH 19 Oct 1972 [19 Oct 1971] 48230/72 Heading G1U The prior art arrangement, Fig. 1, for testing a circuit isolating switch P (i.e. a switch designed merely to break the full load, and not the shortcircuit, current) in such a way as to simulate the conditions the switch would experience in use, requires the use of a generator, shown as an ideal A.C. source G and an inductance Z, whose inductance is of the order of 10 to 20% of the load inductance ZL necessary to provide a lagging power factor of about 50 degrees, is modified as shown in Fig. 3 with the result that the generator impedance Z' can now be 5 to 10 times as large as the load impedance Z L, without reducing the recovery voltage. The alternate generator G has to provide a slightly higher voltage than the original in order to offset the voltage dropped across the resistor R. Thus, with the testing arrangement of Fig. 3, as compared with that of Fig. 1, a given switch can be tested using a generator having a smaller short-circuit capacity.

When the last cartridge passes the feeler 20 the latter is urged in a counter clockwise direction and through a transmission system releases a shaft 11 which is thus rotated by a spring 39 whereupon the support element 40 moves out of contact with a lever 45 attached to a trigger rod 47 and so disconnects the firing mechanism. To fire the remainder of the ammunition between the feeler and breech block the shaft 11 is manually rotated into the position shown by a lever 38 and the lever 45 rocked to reconnect the firing mechanism. When a new belt is connected to the end of the old one, the feeler, shaft and transmission system are relocated as shown, whilst levers 43 and 45, the former being with a trigger housing 42, are rocked to reconnect the firing mechanism. By rocking lever 32 monitoring of belt 19 can be controlled by elements 7a, 8a, 17a and 24a.

Abstract: 1470910 Roll film cameras ASAHI KOGAKU KOGYO KK 9 Dec 1975 [11 Dec 1974] 50326/75 Heading G2A  A roll film camera has a device which rests against the film on the supply spool and which has a frictionally restraining effect on the unwinding of the film therefrom, only when the camera back is open. As shown, the film 12 winds across from the supply spool on shaft 8 to the take-up spool 11. A lever 9 is mounted on a pivot a fixed to the camera body, and is biased clockwise by a spring 10. The lever has a projection c which bears against the back cover 5 of the camera, this cover being attached by a hinge 3. When the cover is open, spring 10 pulls lever 9 clockwise so that projections b thereon engage against the film on the supply spool, thus exerting a frictionally restraining effect on the film as it unwinds. This prevents the film from unwinding too freely during the loading operation, which may give rise to various faults. When the back is closed, lever 9 is pushed anticlockwise, so that the projections b disengage from the film.
