Abstract: 290,727. Lewis, W. Feb. 17, 1927. Moulding-machines.-The roll over plate 5 of a moulding machine is provided with trunnions 6 and cable drums 7 to which are connected cables 12, 13, wound in opposite directions and pulled at different speeds in the same direction. The sand in a flask, not shown, clamped on the plate 5 is consolidated by the operation of a jar ramming machine 1 on which the plate 5 rests. The trunnions have loose wheels 10 which, when the plate is to be inverted, are lifted by rails 8 carried by a frame 25 and pistons 19. The cables 12, 13 are then pulled by drums 16, 17 rotated in the same direction at different speeds by toothed gearing 23 from a double acting piston 24 with an opening 39 adapted to be partly closed by a pin 40 and thus slow down the movement at the right hand end. The flask is then lowered on to a table and, after unclamping, the pattern is drawn by the pistons 19. Undesired transverse movement of the plate 5 is prevented by the continuations of the cables 12, 13 which as indicated at 14, 15 pass over idlers 30, 31 and return to the drums 16, 17. In a modification, the piston 24, Fig. 4, is single acting, the rails 8 being inclined so that the plate 5 is returned to the jarring position by gravity. The trunnions 6 engage slots 27 in trolleys 26 running on the rails 8. The transverse movement of the plate is limited by stops.

Title: Improved method and means for exploding submarine mines
IPC: B63G7/08
Filed: 1941-04-11
Abstract: 581,922. Destroying mines. HENLEY'S TELEGRAPH WORKS CO., Ltd., W. T., HUGHMAN, SIR E. M., and DUNSHEATH, P. April 11, 1941, Nos. 4870, 5598 and 5838. [Class 9 (ii)] For mine-sweeping operations to cause the explosion of submarine mines which are actuated by vibrations applied to the water such as are applied by propelling machinery of surface or under-surface crafts, a device is towed behind a vessel, the machinery of which is insulated, and the device is adapted to generate or transmit vibrations of a frequency and amplitude as will actuate the mines. Combined with the device may also be an arrangement for exploding magnetic mines. The towing vessel 1 may be a sailing vessel or may be propelled by air screw or water jet, screw or paddle propulsion of low power or the propelling motor and screw may be insulated so that vibrations are not transmitted to the hull. The device 2 towed by the ship generates vibrations and transmits such vibrations to the water. The vibrations may be of a variable nature so as to cover a range to ensure explosion of the mines. The device may comprise a water syrene in which the rotating member 9 is rotated by vanes 12 as the body is towed by, a cable, causing impulsive flow of water through the device through apertures 7 and 11 in the fixed and movable plates and consequent vibrations. The device may comprise a rotatable sleeve having inclined teeth to co-operate with inclined teeth on a fixed member to cause vibrations, or two pivoted arms may vibrate toward and from each other, or weights on a shaft rotated from the towing vessel may be enclosed within a shell and strike its surface. Alternatively, the shell may enclose loose balls and be provided with internal fins and external vanes, so that the shell is rotated as it is dragged through the water. The towed body may be rotated through shafting from the towing vessel or vibrations may be caused therein by rotating or reciprocating shafting enclosed in the towing- rope. The vibrations may be set up in the device by forming it as an electric boiler with a keel 30 and radial stabilising fins, the boiler comprising three concentric shafts 31, 32, 33, the central shell being insulated from the others and attached to a towing cable 3 for supplying the electric power. The steam is generated in the boiler and passes to a steam chest 37 and thence to an exit nozzle 39 so that vibrations are set up at this point by the escape and condensation of. the steam. The steam may, howevor, be generated in the towing vessel and passed to the towed vessel through lagged pipes. According to Provisional Specification 4870/41 the towed object may be vibrated through a crank and connecting rod from the towing vessel.

Title: Improvements in electric switches adapted for silent operation
IPC: H01H3/60
Filed: 1938-10-10
Abstract: 520,321. Snap-action switches. GENERAL ELECTRIC CO., Ltd., and EDEN, C. G. Oct. 10, 1938, Nos. 4972/39 (divided out of 507,410), 4673/39 and 7442/39. [Class 38 (v)] In a switch of the kind which is biased to the on and off position and has an unstable position between them, the operating member is arrested wholly or mainly by friction whereby the switch is rendered silent in operation. The description goes deeply into the theoretical considerations underlying the invention, and points out that several known constructions come to rest with a slap, Specification 442,448 being instanced. In Fig. 3, a body A is movable about an axis O from an unstable position (u) into a stable position (s) on either side, and is formed with a point at P<1> separating two slightly curved surfaces P', <p2> and P', P'2 having centres Q'. Q<2>. A plane B parallel to the axis O is urged, as by a spring, in the direction of the arrow so that the spring causes the movement from (u) to (s) and the friction between the curved .surfaces and B arrests the member A. In a modification, Fig. 8, the lower faces of A are plane as shown at 10 on the member 8, and the surface B is in the form of a spring 2 having a hump 3. The dolly 7 comes to rest in its extreme positions without striking the cover, and carries a cam 11 co-operating with a leaf spring 14 on which is a movable contact 13 co-operating'with a fixed contact 12. Specification 507,410 is also referred to in this respect. Other modifications are described and illustrated and other ways of obtaining the friction necessary to produce arrest are set out. The Specification also shows switches with continuously rotatable operating members and rollers co-operating with shaped runways. Specifications 183,968, 195,249, 207,324, [all in Class 38 (v)], and 369,559 also are referred to.
