Title: Expansible bracelet
IPC: A44C5/06
Filed: 1961-07-07
Abstract: 929,520. Bracelets. POON YUEN SANG. Sept. 29, 1961 [July 7, 1961], No. 24685/61. Class 43. An expansible bracelet comprises a series of pairs of links and means for detachably connecting the links together, the means comprising an aperture formed in the surface of one link and projecting means extending from the opposed surface of another link and adapted to engage in the aperture and a looking element pivotally mounted about the projecting means between the links and movable to a position in which it restricts movement of the projecting means and thereby prevents withdrawal of the projecting means from the aperture. Pairs of links a, d have each a base-plate secured to an outer shell, and pivot on a central pivot pin e which houses a torsion spring f. One base-plate of a pair of links has a central hole for the central pivot and end apertures for rivets h which extend through end apertures provided in the base-plate of the other link of the pair. The aperture b 3  has a key-hole shape and the shank of the rivet is retained in the narrower part by a plate-locking element k pivoting on the rivet h at one end, and at the other end having an aperture k 2  which dips on to the central pivot e. The plate has a notch k 4  for engagement by a small pointed tool to facilitate disengagement of the plate from the central rivet to disengage a pair of links.

Abstract: 1,039,832. Electric resistance heating. BADISCHE ANILIN- & SODA-FABRIK A.G. June 26, 1963 [June 27, 1962], No. 25363/63. Heading H5H. In an electrically heated film evaporator for dehydrating caustic alkali solutions, the evaporator tube 1 is heated by passing a current directly through it by means of contact plates 2, 3. A roughened or tapped portion distributes the incoming solution on the inner surface of the tube. A fan (not shown) is coupled to the upper end of the tube to draw off water vapour. In the embodiment described, the tube is 7 m. long, 70 mm. i.d. with 6 m. between plates. Several tubes may be connected in series. The tube wall thickness may vary to alter the evaporation rate of portions of the tube. It is suggested that solutions should be concentrated to 71% by cheaper energy sources before the solutions are fed to the tube.

Title: Improvements in hydraulic starting systems for internal combustion engines
Inventor: ABBEY ARTHUR
IPC: F02N99/00
Filed: 1958-08-07
Abstract: 848,603. Engine turning gear. ABBEY, A. (American Bosch Arma Corporation). Aug. 7, 1958, No. 25412/58. Class 7(5). [Also in Group XXXV] In combination with an internalcombustion engine having an automatic hydraulic starter 32 for cranking the engine, an accumulator 37 connected to the starter for supplying the starter with hydraulic pressure fluid for cranking operation thereof and movable control means 35 associated with the starter for controlling cranking operation thereof, there is provided hydraulic cylinder means 54 connected to the accumulator, the cylinder means comprising piston means connected to the control means for moving the control means to control operation of the starter and valve means 68 included in the connection between the accumulator and the cylinder means for controlling cranking operation of the starter means and comprising an electromagnet including an operating winding 71 for controlling the valve means and the combination further comprises an energizing circuit for the operating winding and switch means included in the energizing circuit for controlling the cranking operation of the starter. Thus when there is a power failure at main bus conductors 14 the solenoid valve operating windings 71 and 73 become de-energized. Inlet valve 68 then opens admitting pressure fluid to the cylinder. Pressure fluid then forces the piston 59 to the left at the same time the bus contactor 19 releases. As the piston 59 moves to the left control lever 35 moves to its operative position whereupon the starter 32 cranks the engine 29. If the engine 29 starts in response to cranking emergency generator 28 immediately builds up voltage and operates the emergency bus contactor 23. Failure of emergency generator voltage at bus conductors 22 will similarly cause re-cranking of emergency engine 29. The emergency engine 29 may always be started manually by operation of manual starting switch 76. In a modification the engine may drive some load other than a generator such as a propeller shaft or pump. The inlet valve is normally de-energized and closed. Pressure is maintained in the accumulator 37 when the engine 29 is running by means of an engine driven pump 46. The engine 10 drives a main alternator or direct current generator 11.

Abstract: 462,589. Ink - ribbon mechanism. BURGESS, A. F. (Smith & Corona Typewriters, Inc., L. C.) Sept. 18, 1936, No. 25439. [Class 100 (iv)] An ink-apply ing means for a ribbon-inking device for typewriting and like machines of the type described in Specification 430,904 comprises a rotary member having a spring coupling concentrically surrounding a portion thereof, the coupling being connected for rotation to the rotary member at at least one end, and out of contact therewith for at least part of its length, an ink-applying disc being secured concentrically to that part of its length and being arranged in a plane perpendicular to the rotary member, so that the outof-contact part of the coupling and the attached disc may be resiliently flexed laterally of the axis of the rotary member by pressure applied to the edge of the disc. The ink-transfer ribbon 5, Fig. 2, is fed through guides 4, and round idler pulleys 6 to a pulley 7 loosely mounted on a stud. The pulley 7 is driven by the ribbon and drives, through gear-wheels 13, 14, 16, the inking-disc 11 and an ink-lifting roller 17, dipping into a reservoir 18 and rotating inside a tube 19. The driven axle-member 12, Fig. 4, of the disc 11 is provided with a shoulder 20 and waist 21. A shouldered nut 26 screws on to the member 12 and to it and to the shoulder 20 a helical spring 27 is secured. A ring 28 is secured inside several turns of the spring, and the disc 11 is secured by means of an annular flange 29 to the same turns. The member 12 is so arranged that the disc is yieldingly pressed against the roller 17, and its resilient mounting, and the loose mounting of the pulley 7 compensate for irregularities in thickness of the ribbon. In an alternative construction the helix is secured at one end to a collar screwed on to a driven sleeve on the axle, and at the other end to a second collar, carrying the disc 11 and mounted to have transverse play on the axle.

Abstract: 815,544. Control of D.C. motors. ALLMANNA SVENSKA ELEKTRISKA A.B. Aug. 23, 1956 [Sept. 2, 19551, No. 25735/56. Class 38 (3). A motor 3 driving a mooring winch is supplied from a constant-current generator 8 and produces a torque which acts continuously in one direction, so that wire is automatically reeled-in when the tension therein is below a predetermined value, and is automatically let-out when the tension increases sufficiently to overcome the torque of the motor. A polarized relay 10a, subjected to the terminal voltage of the motor, is released just before the motor is stalled by the load when reeling-in the wire. This causes contacts 10b to open and de-energize relay 11a, whereby contacts 11b open and resistor 13 is connected in series with the field winding 12 of the motor. Thus the torque of the motor is lowered, and the tension in the wire during the paying-out operation will not greatly exceed the maximum tension obtaining when the wire is being reeled-in. In another arrangement, the excitation of the generator is controlled instead of that of the motor. The generator may be of the Ward-Leonard type.
