Title: Improvements relating to pontoons and the buoyancy control thereof
IPC: B63C7/00
Filed: 1935-10-22
Abstract: 455,824. Raising sunken ships. LEROUX, R. P., 116, Rue des Chalatres, Nantes, Loire Inferieure, France. Oct. 22, 1935, No. 29132. Convention date, March 7. [Class 68 (ii)] [See also Group XXX] , A means for raising a sunken submarine comprises a series of pontoons, Fig. 6, which are towed to the spot and attached to loops 1 on the ship by hand-operated tongs-like hooks 13, Fig. 4. These hooks are at the ends of cables 12 dropped from a salvage vessel, and are attached to the loops 1 by a diver. Alternatively the cables 12 may be unwound from the sunken vessel by released buoys. The cables 12 being in position, the pontoons are guided down them until larger hooks 11 on them engage with the loops 1. Each pontoon consists of an inner and outer casing 5, 4, forming a ballast tank 6 containing compressed-air bottles 29 by means of which water is expelled when desired from the tank 6. The casing 5 encloses a driving- apparatus 7 for a winch 9 for winding up the cable 12. The device, Fig. 4, for causing the hook 11 to engage with the loop I comprises compression springs 19 or equivalent devices in cylinders 16. The device passes down the cable 12 until the collar 26 meets the cone 15, when the distortion of the wires 23 &c. causes the latches 22 to release the pistons 17, and enables the springs 16 to close the hooks 11 over the loops 1.

Title: Improved stroke adjuster for wind-motor-driven pumps
IPC: F03D11/02
Filed: 1957-09-16
Abstract: 831,242. Wind-motors. AUCAMP, J. D. Sept. 16, 1957 [Oct. 23, 1956], No. 29163/57. Class 110 (3). [Also in Group XXVIII] An automatic stroke adjuster for use with wind - motor driven pumps comprises an hydraulic cylinder and piston assembly which is disposed between two portions of the pump rod, the hydraulic piston being attached to one portion of the pump rod and the hydraulic cylinder being attached to the other portion of the pump rod. An hydraulic fluid reservoir is provided, also a constricted passageway allowing flow of fluid from the space in the cylinder above the piston to the reservoir, and means for allowing a relatively unrestricted return flow of the liquid from the reservoir to that space. The upper part of the pump rod 2 is connected at its upper end to the driving crank and at its lower end to the hydraulic piston 9 which is disposed in the hydraulic cylinder 4, the lower cover 6 of the cylinder being secured to the lower part of the pump rod 2 on which is mounted the pump bucket 32 disposed in the pump barrel 11. The hydraulic cylinder is also provided with an upper coverplate 5 and an intermediate partition 7, the space 8 above the partition 7 being connected by a duct 28 to the space 29 in the cylinder below the piston 9, the spaces 8 and 29 together forming an hydraulic fluid reservoir. A spring- loaded valve 14 is disposed in the partition 7, a groove 18 in the side of the valve chamber permitting fluid to pass from the space 3 above the piston 9 to the reservoir space 8 when the valve is not seated on the seating 19. Non- return valves 30 are mounted in the piston 9 to allow fluid to pass from the reservoir space 29 to the space 3 above the piston. With the wind-motor working in a fair breeze, and with the piston 9 at the bottom of the cylinder 4 the pump bucket 32 will act through a full stroke, since when the upper part of the pump rod 2 and the piston 9 commence an upward stroke, the pressure created in the fluid in the space 3 above the piston will cause the valve 14 to close after a slight leakage through the groove 18, so that the cylinder 4 and lower part of the pump rod 2 and the pump bucket move upwardly with the upper part of the pump rod. In conditions of light breeze however, the pressure created in the fluid above the piston 9 by upward movement of the piston will not be sufficient to close the valve 14, so that fluid will escape through the groove 18 into the reservoir spaces 8, 29; the pump bucket 32 will then rise only a portion of its full stroke. During the downstroke under these conditions, fluid will flow into the space 15 above the piston 9 through the valve 14 but mainly through the valves 30 in the piston 9. The reservoir space 8 could be dispensed with by providing a valve assembly such as 14 in the piston 9. Again, the reservoir space 29 could be dispensed with by providing valves such as 30 in the partition 7 instead of in the piston 9.

Seal fastenings; strap, chain, and cord fastenings.-In the seal fastening described in the parent Specification the central opening 6 in the plate or container 1 has the shape of a rightangled triangle. The plate 1 has an upturned edge 2 which is cut away on both sides of a diameter at 3, 4, and a slot 5 is cut parallel to the diameter 3, 4 in the position shown in Fig. 2. A tongue 8 is stamped out adjacent to the cut-away part 4 of the rim 2. The edges 7 of the slot 5 and central opening 6 are bent over to avoid cutting the tape. The end of the securing- tape 9 is passed through the opening 6 and through the slot 5 forming the portions 9b, 9<a> shown in Fig. 3. The end 9<a> is thus secured, and the tape can be pulled tight round the package and passed through the opening 6 in the direction 9<c>. The hypotenuse of the triangular opening 6 causes the tape to fold in the direction 9<a> without twisting and the tape is passed round the package and passed through the hole 6 in the direction 9<e> and the end 9f secured under the tongues 8, as shown in Fig. 4. Sealing-wax is then poured into the shallow container formed by the upturned rim of the plate 1, to seal the ends of the tape.

Title: Improvements in and relating to carriers for mechanically-effecting records of vibrations, such as sound waves
IPC: G11B3/00
Filed: 1933-10-27
Abstract: 426,659. Sound and like records. DICKER, S. G. S., 20, Holborn, London. -(Naamlooze Vennootschap Philips' Gloeilampenfabrieken; Emmasingel, Eindhoven, Holland) Oct. 27, 1933, No. 29895. Drawings to Specification. [Class 40 (ii)] Relates to carriers adapted to receive records of sound and like vibrations, the record being made mechanically and being capable of optical sound-reproduction or photographic copying. According to the invention, the material in which the record is cut is gelatine which is so prepared before use that it has a water content best suited to the action of the cutting tool. For this purpose the carrier is dried in such a manner that the water contained in the gelatine is in equilibrium with the water vapour in air or like surrounding medium having a relative degree of humidity of 20 to 50 per cent. The drying may be effected by cooling filtered air, to determine the dew-point, heating the air until it has the required humidity, and then passing a current of this air, at a suitable speed, over the gelatine. A preliminary treatment of the gelatine, to remove the less strongly-bound water, may be effected by passing the carrier through an alcohol bath. The dried carriers are preferably kept, before use, in waterproof packing. Graphs are given in the Specification, to illustrate the principle of the invention.
