Title: Improvements in and relating to bombs and projectiles for use in aerial warfare
IPC: F42B10/56
Filed: 1940-06-21
Abstract: 541,277. Bombs and projectiles; aerial warfare. MOTLEY, L. June 21, 1940, No. 10690. [Classes 9 (i) and 9 (ii)] Bombs and projectiles for aerial warfare and of the kind described in Specification 498,595, comprising a parachute and two or more explosive containers adapted to be separated from one another in the air and suspended from the parachute, are arranged so that the parachute is first separated from the container units which are separated from each other afterwards. The projectile shown comprises a container 1 for a packed parachute and two containers 2, 3 of high explosive. The container 1 is separated from the other units by a separating charge fired by a fuze 8 ignited by a cap 9 which is struck by a striker 14. The latter is carried by a piston 13 slidable in a cylinder 12 at the base of the projectile and propelled forwards by compressed air used to discharge the the projectile from the mortar. The units 2, 3 are mounted on a hollow rod 6, enclosing the fuze-cord 8, and are normally secured thereon by a pivoted spring latch 7 on unit 2. The latch is connected to the parachute (not shown) by cords 4, and it is the jerk on the cords that releases the latch and allows the two units to become separated, through inter-connected by a cord 5. The ends of the cord 5 are attached to striker levers 19 (one only being shown) each of which is pivoted at 20 on its unit and fixed by a shear-pin 22. The jerks due to separation are insufficient to shear the pins 22, but should an aircraft foul the cable 5, the pins will be sheared and the strikers 19 caused to fire detonators 21 and explode the units. The projectile has a gas-check ring 11 as described in Specification 541,274. The application of the invention to a stream-lined projectile having the parachute housed in the rear container is also described.

Title: Closure for the sheath of a nuclear fuel element
IPC: B23K15/00
Filed: 1975-03-14
Abstract: 1492452 Fuel elements STICHTING ENERGIEONDERZOEK CENTRUM NEDERLAND 14 March 1975 [15 March 1974] 10796/75 Heading G6C A method of forming nuclear fuel elements comprises closing a plurality of sheaths by flattening the walls of each sheath to form one or more closure regions, arranging the closure regions of the sheaths side by side, and welding together the flattened walls of each of the closure regions by means of an energy beam weld or welds. Such a weld is one in which use is made of a laser beam or an electron beam, or an argon arc weld. By arranging the closure regions side by side, a number of them can be welded practically simultaneously, the welding operation being performed along a single welding track or alternatively along two parallel welding tracks. In the fuel element shown in Fig. 6, the sheath 12 is provided with tube ends 2 that have been flattened and welded as well as with flattened intermediate tube portions 9, 13. In the flattened tube portions 9, 13, the welded bands 14 are interrupted as at 15 to enable the fission gases to escape as indicated by the arrow 16 from one compartment to the other. Alternatively (Figs. 7 and 8, not shown), either a single or two parallel axially extending welded bands are used. The flattened tube portions 9, 13 are in planes at right angles to each other so as to render the sheath 12 equally resistant in all directions against the forces acting upon it such as, for example, those resulting from bending moments and buckling moments.

Title: Improvements in or relating to protective control systems for electric motors
IPC: H02H7/00
Filed: 1943-07-03
Abstract: 568,336. Protective cut-out arrangements. BROOKE, W., and BALDWIN, H. T. July 3, 1943, No. 10837. [Class 38 (v)] A remote-control and protective system, suitable for supplying mining apparatus over a trailing cable, and of the type wherein a main contactor is controlled by a remote switch (usually at the apparatus location) over a pilot circuit (usually incorporated in the trailing cable) and a relay device, employs as the relay a gas-filled triode the grid-potential of which is controlled by the remote switch. for operating the main contactor. The relay f controlling the latter is in the anode circuit of the valve F the grid of which is normally biassed against operation by an alternating-potential derived from the winding s<1> of a transformer H, the grid being connected to the mid-point of resistances g, k. A suitable bias-voltage is 15 volts, but by dispensing with k, 30 volts may be obtained. For connecting the grid n direct to the cathode, which is earthed at a to the gate-end box A, the pilot and earth-continuity conductors are connected to one another at will by a control switch G at the motor-location, so enabling anode current to flow, but if the pilot circuit becomes opened due to opening the switch G or mechanical fracture of the conductors, the grid-bias is re-applied and the motor stopped. When k is dispensed with, the earth-connection from a is taken to the left-hand end of s<1> and an inductance is connected by the switch G in parallel with the resistance g, either at the gate-end box, Fig. 2 (not shown), or at the motor, Fig. 3 (not shown), the latter arrangement additionally providing protection against short-circuiting of the pilot circuit. This last arrangement may be further modified to provide against automatic restarting after a supply failure, for which purpose the switch G has another contact u, Fig. 4, for short-circuiting the inductance t. When the supply is restored, and contact u is engaged, a reset relay J is energized from s<1> over leads 7, 8 and contacts v<3> of a no-volt relay K, the coil, y of which is energized, by closure of contacts x of relay J, over a circuit including conductors 11, 10 connected to s<1>. Relay K makes its own holding circuit at v<1> and the anode circuit at v<2> and opens at v<3> the energizing circuit of J. When switch G is changed over, the valve F is made conductive and the motor runs, but if the supply fails and is restored, the relay J cannot be re-energized to re-start the motor until switch G is moved over to contact u to cut out the inductance.

Title: Improvements in or relating to steam traps
Inventor: MARX FRANK RALPH
IPC: F16T1/08
Filed: 1964-03-17
Abstract: 1,055,902. Steam traps. SPIRAX-SARCO Ltd. Feb. 26, 1965 [March 17, 1964], No. 11304/64. Heading F4U. A steam trap of the kind described in Specification 755,178 has a temperature-controlled bleed valve 19 for allowing escape of fluid from the control chamber 9 when the temperature in the chamber is below a predetermined value. As the pressure rises in the steam plant condensate and air entering an inlet 2 passes up a bore 10, lifts a plate valve 16 and flows to the exhaust 3 portly by way of a groove 12 in the under-face of the valve 16 and passages 13, 15, and partly through the bleed valve 19 which is kept open by a bimetallic disc 26. As soon as steam arrives at the trap it flows into the chamber 9 and through the bleed valve 19 into the space 18, heating the bimetallic disc so that it becomes less dished and allows the steam pressure to close the valve 19. The rise in pressure in the chamber 9 causes the valve plate 16 to seat upon the groove 12 and escape of steam through the trap is prevented. When the pressure in the control chamber 9 drops the plate valve 16 is unseated and the hot condensate flows to the exhaust port 3. If, however, the drop in pressure in the chamber 9 is not sufficient to allow unseating of the plate valve 16 to discharge condensate, the fall in temperature causes the bimetallic disc 26 to become more dished and open the valve 19, whereupon the pressure in the chamber 9 is reduced and the plate valve 16 becomes unseated. Condensate is thus discharged; steam arrives in the chamber 9 and the bimetallic disc contracts allowing the steam pressure to close the valves 19 and 16. In a modification, the bleed valve closes the top of the valve orifice 23 and the bimetallic device is such that it expands with increasing temperature and maintains the valve 19 closed until the temperature in the chamber 9 drops.
