Title: An Improved Marine Portable Life-saving Device.
Inventor: DRIJENKO CONSTANTINE THEODOROV
IPC: B63C9/06
Filed: 1918-03-21
Abstract: 124,282. Drijenko, C. T. March 21, 1918. Pontoon rafts, collapsible, A portable marine life-saving device in the form of a raft, boat, or canoe comprises an open frame F with closed sheet-metal floats 1 .. 4, Figs. 3 and 8, hinged to the sides and ends thereof so as to fold outwards therefrom to form the bow, stern, and side portions of the raft, or inwards within the limits of the frame so that the device resembles in outline a travelling-trunk portable by one man. A mast MT, with sails SL, or paddles P are provided to propel the raft, and a rudder RR can be fitted. Anti-friction castors AK may be fitted to the frame, and the hinges may have springs Sp, Fig. 6, tending always to open out the floats 1 . . 4. A bottom plate B, with or without an inner bottom IB, is collapsibly connected to the frame or the inboard edges of the floats to form a central well, and there may be hinged U-shaped struts to keep the bottom down. A water-tight cloak K with sleeves, neck-hole, helmet, and hood is fitted. The cloak may also have sleeves or tubes leading to the hollow floats for access to the contents thereof. Revolving hook-claws R retain the floats when folded inboard. When turned outwards, the floats are pulled into position by hauling-lines HL which pass through tubes U, and are locked one to the other by sliding bolts T<1> operated by a further pull on the lines HL. The floats are further held down by tension straps TS connected to, and stretched by, the bottom plate B. A selfstopping lowering winch N, Fig. 6, attached to the ship's rail by a snap-catch N<2>, is connected to, and travels with, the raft, and is fitted with a spring-controlled friction clutch released by the handle NH to pay out the lowering-line N<1>. Two releasing-devices R<1>, R<2>, one for the raft and the other for the operator's belt LB, are then operated to let go the raft from the launching-line N<1>. A further device for lifting the raft over the ship's rail to aid launching comprises rotary and folding-hooks HK, Fig. 4, connected by a hinged piece HP to a sliding frame SF within the main frame F. These hooks are first released by a draw-catch rs<4> from a folded position, and are then hooked on the ship's rail with the raft hanging inboard; a launching-line LG passing over purchase pulleys P', P<2> in the frame F is then operated and raises the raft up to the rail and tilts the same over so that it can then be lowered by easing out the launching-line.

Title: Improvements in or relating to flash light accessories for photographic cameras
IPC: G03B15/04
Filed: 1944-01-04
Abstract: 564,326. Flashlight apparatus for photographic cameras. BATTING, S. W. Jan. 4,1944, No. 5395/43. [Class 98 (i)] In a flashligh accessory for attach ment to or incorpora tion in a camera, of the kind comprising a main circuit adapted to be closed by the movement of the camera shutter and including one or more flash bulbs, and a flash bulb testing circuit having in series with the bulbs a test lamp which serves as a resistance to prevent firing of the bulbs when the test circuit is closed, a two-position switch so controls the test lamp and main flash bulb circuits that unless this switch is set to close the test circuit it is impossible to fire the flash bulb, and so the test lamp glows continuously until release of the camera shutter closes the main circuit. In its other position, the switch cuts out the flash bulbs and closes a shutter-testing circuit including a pilot lamp. There is also an independent circuit containing a lamp (which may be the pilot lamp) and switch for signalling that the exposure is about to be made ; and a plug-in arm carrying sockets for two or more flash bulbs with a switch which can be set to fire the bulbs simultaneously or successively. As shown, the operating circuit A, Fig. 1, includes flash-bulb sockets B, B<1>, B<2>, in parallel, a dry battery C, a two-way switch F and contacts A<1> adapted to be closed momentarily by the camera shutter when making the exposure. An auxiliary circuit D contains a test lamp E which glows when the switch F is in the full-line position if the flash bulb is satisfactory, but which by its ' resistance prevents firing of the bulb until contacts A<1> are closed. A further circuit G containing a shutter-circuit test lamp H is closed when switch F is in the dotted-line position and the camera shutter is actuated ; and the lamp H, or a separate lamp, may be energized by an independent circuit J controlled by a switch J<1> to signal the imminence of exposure. Sockets B\ B<2> are arranged to receive respectively horizontally and vertically a plug-in arm K, Fig. 2, carrying several flash bulbs K<1> and a selector switch L permitting any one or all of the bulbs to be fired. If the device is attach'- able to the camera, the elements are housed in a casing which may be secured to a side wall of the camera. Specification 363,050 is referred to.

Title: Improvements in or relating to pelleted polychloroprene
IPC: C08J3/12
Filed: 1957-02-19
Abstract: Uniform, free-flowing pellets of plastic polychloroprene coated with a powder which does not react with the polychloroprene under normal atmospheric conditions are prepared by suspending drops of an aqueous dispersion of the polychloroprene in a water-immiscible organic liquid more volatile than water and in which the polychloroprene is insoluble, at a temperature below - 20 DEG  C. until the drops are frozen and the polychloroprene coagulated, the pellets are separated and coated while still frozen with 5 to 20 per cent of their dry weight of the powder, and water and any adhering organic liquid are removed by vaporization by warming.  Suitable organic liquids are aliphatic hydrocarbons and fluorinated aliphatic hydrocarbons and fluorinated aliphatic hydrocarbons such as petroleum ether.  The drops may be formed by known means before the latex enters the liquid or may be formed by directing a stream of latex at the surface of the cooled liquid, in which case the size of the drops and hence the pellets may be varied by adjusting the size and velocity of the stream, or by violent agitation in contact with the liquid.  Suitable powders are talc, starch, soda ash, carbon black and powdered chalk and an active accelerator may be mixed therewith, the drying temperature is preferably less than 50 DEG  C. and must not be so high that the pellets coalesce; a stream of warm air is suitable for drying.  Normal antioxidants and stabilizers may be added to the polychloroprene.  The polymer latex may be formed by normal emulsion processes.

Abstract: 381,453. Correcting inductive disturbance. SIEMENS & HALSKE AKT.- GES., Siemensstadt, Berlin. Feb. 27, 1932, No. 5927. Convention date, Feb. 28, 1931. [Class 40 (iv).] Noise voltages due to different voltages (longitudinal voltages) being induced in the conductors of a cable circuit by an interfering source are compensated by tapping off a suitable longitudinal voltage and, after requisite phase change, applying it to the circuit. The longitudinal voltage may be taken off other conductors in the same cable, or from the sheath or from a special thin conductor in the cable. As shown, the longitudinal voltage induced in the conductors 1 by a source 2 is taken off a centre-tapped transformer 4 over a circuit including resistance 6 and capacity 7. The compensating voltage is tapped off resistance 6 and applied by a coupling 9 to a transformer in the input circuit of repeater 3 or in an intervalve coupling in the repeater. A coupling circuit may be common to a number of different circuits in the cable, or when different noise voltages occur in the various circuits separate couplings may be taken from different points on the resistance 6.
