IPC: C10H9/00
Filed: 1916-08-12
Abstract: 101,156. Margreth, J. Aug. 12, 1915, [Convention date]. Regulating head of liquid directly; solid in separate charges in generator. - The generating- chamber of an acetylene-generator consists of two concentric bells, the inner one containing the carbide vessel and serving for the generation of the gas, while the outer bell collects the " after gas " and leads it to the gas-bell; each bell communicates by a tube with the gas-bell, and the generating and gas bells are immersed in a common water tank. The generating-chamber may be rigidly but removably connected with the gas-bell. In the construction shown in Fig. 1, the annular gas-bell d surrounds the double generator-bell a, b, and is immersed in a water tank f; the inner bell a contains the carbide vessel and gas generated passes by a pipe g to the gas-bell d. When the cock h is closed, the after gas forces the water out of the bell a and escapes by the lower edge i to the bell b and thence by pipes k, l to the gas-bell. The pipes g, k, l form a rigid coupling between the bells a, b and the gas-bell; a screw-coupling m allows removal of the bells a, b. Gas for consumption is led off by the cock o. In modified constructions, the double generator-bell is immersed in the water tank at the side of the gas-bell and connected therewith by a flexible pipe, the rigid coupling being effected by a lug extending upwards from the bell band passing through and clamped to a slot in a projection extending from the gas-bell. Specification 9373/14 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) describes also a further modification, Fig. 4 (Cancelled), in which the inner and outer bells a, b are connected by a pipe l, the and opening into bell b being at a lower level than the top of the carbide-container w; the carbide is placed on a series of horizontal trays t<1> - - t<5> of semi-cylindrical cross-section; water enters by an opening v and passes under a partition x to the bottom of the carbide-container. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to automatic photographing apparatus
IPC: G03B17/53
Filed: 1954-04-21
Abstract: 757,823. Photographic cameras. INTERNATIONAL MUTOSCOPE CORPORATION. April 21, 1954 [June 17, 1953], No. 11492/54. Class 98 (1). In apparatus for taking and developing a photograph automatically, the film cannot be advanced if a frame. is not correctly disposed in the exposure position and when the trailing end of the film reaches this position. As shown, in a coin-freed automatic camera, the non- engagement of check-pawls 76 in the perforations 70 prevent the starting switch 98 from being operated and coins are returned to the customer through shoot 94. Preferably, the film F has perforations 70, between each frame, and is fed along a guideway 10 by the reciprocatory motion of a claw carried in a carriage 22 sliding on guide rails 20. The film in the exposure position E is replaced by a single rotation of the member 48, the exposed film being severed from the unexposed and passed to a development chamber D. In the closed condition of switches 84 and 110 the coin blocking electromagnet 100 is energized and the coin-blocking member 104 is retracted so that a coin can enter shoot 96 and momentarily close switch. 98. Relay 114 is then energized and contacts 114C and 114D, start the operating mechanism 56 while the relay is held by contacts 114A and 114B. Motor 55 immediately starts to return carriage 22 to the beginning of a feeding stroke and the film at E is exposed before the carriage reaches the position shown in Fig. 2. Motor 55 also operates cams 127 and 129 which ensure that switch 126 is closed before switch 110 is opened to re-set relay 114 and block shoot 96 by de-energizing magnet 100 without interrupting the operation of mechanism 56. As shown in Fig. 2, claws 36 displace pawls 76 from perforations 70 and feed the exposed frame into the development chamber D and the next unexposed frame into the exposure position E. A single revolution of member 48 is completed as the claws 36 are withdrawn from the perforations at the end of the feeding stroke and switch 110 is closed by cam 127 before switch 126 is opened, to stop motor 55 and operating mechanism 56, so that, if pawls 76 are properly engaged, the coinblocking member 104 will be withdrawn. The trailing end of the film is not provided with perforations 70 so that switch 84 remains open when it has been reached. U.S.A. Specifications 1,167,314, 2,218,656, 2,380,378 and 2,532,855 are referred to.

Title: Improvements in or relating to apparatus for corrugating or ridging non-flaccid material
IPC: A41H33/00
Filed: 1932-04-23
Abstract: 381,874. Corrugating or goffering collars for personal wear. SHAW, H. S. HELE-, 64, Victoria Street, London. April 23, 1932, No. 11742. [Class 141.] The neckband of a collar is corrugated to the form shown in Fig. 1 so as to enable a necktie to be more readily adjusted to it. Apparatus for carrying out this process is shown in Fig. 3, and comprises a pair of rollers 43 with intermeshing teeth between which the neckband of the collar is passed by hand. The upper roller is mounted at both ends in a frame 31 which also carries one end of the lower roller. The other end of the lower roller is supported as shown by a cranked standard 41 to allow of free passage of the collar. In another construction free movement of the collar is obtained by mounting the lower roller at one end only. The rollers are rotated by a crank and handle as shown. The teeth of the rollers adjacent the position of the fold 15 of the collar are rounded off at 13. For leading a collar to the rollers a guide 61 is employed which is flared at the entrance part to facilitate insertion of a collar. The guide has a horizontal channel 63 for the band and a vertical channel 69 for the collar top. There is an extension 65 for the locking tab 16 of the collar. A guide 71 presses against the edge 17 of the collar band by spring action, which is released by a handle 83 to allow of insertion of the collar. The rollers are spring- pressed, the pressure being adjusted by screws 51. Rotation may be obtained by power. Between the driving mechanism and the corrugating rollers, a free-wheel device may be placed, so that reverse movement of the rollers may be prevented. If desired a counting mechanism may be.incorporated in the machine and this may be actuated by movement of the guide 71 or of an associated part.

Title: Improvements relating to gas or air bags and salvage methods for raising sunken vessels and other objects
IPC: B63C7/12
Filed: 1917-08-21
Abstract: 165,454. Ryan, A., and McKechnie, Sir J. Aug. 21, 1917. Sunken ships and other objects, raising. - In raising sunken ships and other objects by means of gas or air bags attached to cables connected to the ship &c., the lifting operation is carried out in successive stages, the length of the cables or the position of the bags thereon being so adjusted that the bags are located beneath the surface of the water before each lift to an extent which corresponds to the distance through which it is desired to raise the vessel &c. at any one stage. The lifting - cables g may have a series of rings g<1>, g<2>, g<3> at the desired distances apart. Bags A<3>, A<4> are secured to the sides of the vessel and additional bags A<5> are secured to the ends of the lifting cables g at a distance below the surface corresponding to the desired first lift. The bags are inflated and the vessel rises until the bags A<5> reach the surface. Fresh bags are then secured to the rings g<1> and inflated to raise the vessel another stage, the bags A<5> being then deflated and removed. This process is repeated until the vessel is raised sufficiently to be towed into shallow water. Bags may finally be attached to short cables passing under the vessel, which may thus be raised sufficiently to be brought into dock. Too rapid a lift is prevented by opening a valve in the inflation pipe and allowing the air or gas to escape gradually. The lifting may also be controlled by cables 1 connected to the sunken vessel and carried by winches on the salvage vessel. Additional surface bags or buoys may be attached to the submerged vessel, so that should any downward motion of the vessel take place it tends to submerge these bags or buoys, which thereby prevent the vessel from sinking again. In such an emergency, additional air may also be admitted to the lifting bags. The bags are constructed and operate as described in Specification 165,630. The bags may be applied to submarines, each bag being normally contained in a deflated condition within compartments protected bv cover plates. The removal of the covers, the release of the bags from the compartments, and the inflation of the bags may be controlled from inside or from outside the submarine.
