Title: Improvements in or relating to hydraulic stabilising devices for vehicles
IPC: B60G21/073
Filed: 1934-04-09
Abstract: 420,352. Vehicle suspensions; hydraulic shock-absorbers. HOME, H., 30, Akazienallee, Essen, Germany. April 9, 1934, No. 10721. Convention date, April 15, 1933. [Classes 108 (ii) and 108 (iii)] In an hydraulic stabilizing device for vehicles of the kind in which a double-acting shockabsorber S is mounted on each side of the vehicle and the working chambers of the two shock-absorbers are interconnected by pipes G, H, provision is made so that for gentle jolts the device acts as a simple shock-absorber only, but on the occurrence of sudden heavy shocks the full stabilizing effect results, such action being obtained by the inclusion, either between two chambers of the opposite shock-absorbers or between the two chambers of each shockabsorber, of a constricted byepass, which is preferably adjustable. In the arrangement shown in Fig. 1, the additional connection is constituted by a pipe K extending between the opposite chambers A, D, the byepass d' comprising a conical adjustable pin working in a conical passage. In each shock-absorber two pistons T connected to the ends of a rocking- lever U work in the chambers A, B or C, D, the lever U being rigid with a spindle V, to which is also secured an arm E connected by a link e<1> to the axle or other unsprung part of the vehicle. In the case of a low-speed movement affecting, say, the left hand shock-absorber, liquid may pass substantially freely between the chambers C, D via the pipes F, K and chamber A without producing any effect on the right-hand shock-absorber. In the case of a high-speed movement, the byepass d' is operative to check any sudden flow of liquid, and consequently the liquid displaced from one shock-absorber produces a corresponding effect on the other shock-absorber, with the result that the vehicle is stabilized. Dashpots.-In a modification, Fig. 3, the constricted passage is formed between the two chambers A<1>, B<1> of the shock-absorbers, these chambers communicating by ports m<2>, m<3> with a bore m<1> in a boss M. Adjustably disposed in the boss is a stud N formed with labyrinthal grooves m<1>, while a helical spring R bearing upon the inner end of the stud increases the resistance to liquid flow by causing eddy currents.

Title: Improvements in or relating to bombing mechanism for aircraft
IPC: B64D1/04
Filed: 1936-04-14
Abstract: 456,959. Bomb-dropping. RHEINMETALL-BORSIG AKT.-GES., 125, Ulmenstrasse, Derendorf, D³sseldorf, Germany. April 14, 1936, No. 10752. Convention date, April 11, 1935. [Class 9 (ii)] Relates to bomb-dropping devices which are adapted to be hoisted in position in an aircraft, and consists mainly in the provision of means whereby the bomb cannot be released when the device is removed from its normal position in the aircraft. In the form shown, a pair of bomb-holding arms c are pivoted at d on a frame b and are formed with jaws c<6> for gripping the lug m of the bomb. springs tend to open these jaws, but they are retained in the closed position by hooked arms e provided with lateral pins e<1> fitting in slots f<1> at the ends of leversf which are pivoted on sleeves k and interconnected at f<3> to ensure their simultaneous operation. Springs are provided to hold up the outer ends of the levers f until the bomb is to be dropped. For this purpose, the outer ends of the levers are forced down by any suitable means, whereupon the slots f <1> causes the pawls e to be deflected and release the levers c and allow the bomb to fall. The frame b is attached to a hoisting cable by a pin a. To load a bomb the frame with the jaws open is lowered on the bomb, the lug m on entering between the jaws strike the upper prongs c<7> of the jaws and swing the levers c to the closed position where they are held by the hooked arms e. The ends c<3> of the arms c are pivoted and spring controlled to allow them to pass into the hooked arms e. The frame b is then hoisted up to its position in the aircraft. To prevent premature release of the bomb, the levers f are locked in the closed position by means of a spring bolt g mounted on the frame b. The spring g<1> of this bolt holds it with its end g<3> projecting into a sleeve k and with a lateral projection under a shoulder on a lever i attached to a lever f. In this position the levers f cannot be moved to release the bomb. When the frame b has been hoisted in position in its chamber on the aircraft, the sleeves k come opposite corresponding holes in the wall of the chamber, and pins are inserted through the holes and the sleeves to fasten the frame. At the same time, this locking operation wedges the bolt g aside and unlocks the levers f. The pin a is locked in a similar manner by a tooth on a spring bolt so long as the end of that bolt projects into a sleeve k ; this prevents the hoisting cable being detached before the frame is fastened by the pins. In a modification, the pin a is locked by a transverse spring bolt and a stud projects into a longitudinal groove in the pin to prevent its complete passage through the device when inserted.
