Abstract: 331,591. Vickers-Armstrongs Ltd., and Dickson, B. W. A. April 6, 1929. Divided on 331,587, [Class 9 (ii), Torpedoes &c.]. Hooks, spring, safety, slip, and closed.-Relates to bomb-dropping hook-devices supported by a winding gear from an aircraft, and consists mainly in making the hook B pivoted at B<1> with a longitudinal extension B<2> resting over a compression member B3 pivoted at B<4> and carrying a catch E pivoted at E<1> and hooking over the extension B2. The catch is held in place by a spring E<3> extending between it and a tail projection on the hook B. To release a bomb, a wire E<2> is pulled. This rocks the catch E about its pivot E<1>, thereby unhooking it from the extension B<2>. Continuation of the pull now rocks the compression member B<3> away from the extension B<2>, thus releasing the hook B and allowing the bomb to fall. These various members are mounted on a frame C which is suspended from the aircraft by the wire cable D of a winding gear which is described in Specification 331,587, [Class 9 (ii), Torpedoes &c.].

Abstract: 1532125 DC motor control circuits SIEMENS AG 25 March 1977 [26 March 1976] 12712/77 Heading H2J In a conveyer system having a plurality of railcars driven by respective D.C. motors and running on a rail network including at least one inclined, e.g. vertical, section and provided with current supply conductors S1, S2 for the motors, the conductors are connected to a current source N through a circuit arrangement including switching means T3 arranged to provide an electrically conductive path between conductors S1 and S2 if the voltage between the conductors exceeds the voltage of source N by more than a predetermined amount. This occurs when regenerative operation of one or more D.C. motors of descending cars (e.g. car F1) causes build-up of an excess voltage which cannot be reduced sufficiently by motors of other railcars (e.g. motor M of car F2), and when the current supply fails. A threshold circuit SS responds to the excess voltage to trigger transistor T3, which could be replaced by a thyristor. An additional turn-off circuit would then have to be provided.
