Title: Implement for stitching or similar operations
Inventor: TAYLOR ROBERT REGINALD
IPC: A61B17/04
Filed: 1967-08-02
Abstract: 1,249,853. Sewing implements. R. R. TAYLOR. 28 Oct., 1968 [2 Aug., 1967], No. 35584/ 67. Heading D1G. [Also in Division A5] In a surgeon's stitching implement, an elongated hollow body 1 has a main bore containing a hollow piston 13 having an extension 12 of reduced diameter received in a reduced bore 11 of body 1. The bore in piston 13, which has a larger diameter than extension 12, receives a piston 16. Body 1 is closed adjacent extension 12 by a member 9 journalling a body 4 which is rigid with a handle (not shown) and contains air supply and exhaust pipes 2 and 3 is associated with a valve 5 from which projects a tube 15 slidable in a passage 14 extending axially through extension 12, the arrangement being such that relative rotation between bodies 1 and 4 in opposite directions serves to pressurise and exhaust the space between extension 12 and piston 16, while the space in front of extension 12 is permanently pressurised. The opposite end of body 1 is closed by a member 6 slidably receiving tubular rods 7 and 8 formed at their inner ends with blocks 7B, 8B. A rod 7A slidable within rod 7, is rigid with an extension 13A of piston 13 and a compression spring 7C is interposed between block 7B and extension 13A. A rod 8A, slidable in rod 8, is rigid with a block 18 slidable on extension 13A and block 18 is connected by a rod 17 with piston 16. A compression spring 19 is interposed between extension 13A and piston 16. The outer end of each rod 7 and 8 is cut away as at 20, is provided with a pivot pin 22, and is formed with a flat surface 26 radial to pin 22. The outer end of each rod 7A and 8A is formed with a goosenecked portion 24 and is provided with a pivot pin 25. A movable jaw member 23 is pivotably mounted on pins 22 and 25, the arrangement being such that when the rods 7A, 8A, move outward, member 23 pivots counterclockwise on pin 22 to engage a flat surface formed thereon with surface 26, whereby a surgical needle is gripped in a notch 27 formed in said flat movable surface. In use body 1 is turned relative to body 4 for pressurising extension 12 only, whereby piston 16 moves leftwards till block 7B engages member 6. Further movement serves to compress spring 7C and to clamp a movable needle to rod 7. Body 1 is then rotated about its axis to pass the needle point through the work. Relative movement between bodies 1 and 4 then applies pressure to piston 16, whereby piston 16 moves leftwards to compress spring 19 and block 8B engages member 6 and spring 8C is compressed during closure of the jaw associated with rods 8, 8A upon the pointed end of the needle. Piston 13 will then move rightwards due to differential pressure acting thereon, further compressing spring 19. During initial movement when spring 7C is released the jaw associated with rods 7, 7A releases the butt end of the needle, rod 7 then being retracted. Body 1 is then again turned about its axis to pass the remainder of the needle through the work.

Abstract: 1398425 Ceramic-metal seals GENERAL ELECTRIC CO Ltd 22 June 1973 [1 Aug 1972] 35918/72 Heading B3V Before sealing with a reactive solder a refractory metal component to one having a high alumina content, the surface of the alumina component is fused to seal any cracks therein. Niobium end closures may be sealed to sodium vapour discharged lamps using the reactive solders described in Specifications 1,065,023 and 1,318,658. Alternatively, solder washers of Zr, V and Ti may be used with the Zr against the alumina and the Ti against the metal. The lamp envelope may be formed of crystalline or polycrystalline alumina and may be preheated to at least 1500‹ C., e.g. 1600‹ C., to avoid cracking when the ends are further heated by an oxyhydrogen flame to fuse them and produce a rounded profile. Pre-heating may be by flame or by a carbon susceptor within an eddy current heating coil, the envelope being rotated. Electric heating is effected in a bell jar filled with nitrogen and through the top of which an oxy-hydrogen blow pipe is inserted. After fusing one end the position of the envelope in the susceptor is reversed. The reactive soldering operation is performed at 1500Œ50‹ C. in about 10 minutes under an end load of 10 kg.

Abstract: 919,168. Optical apparatus. SICK, E. Oct. 26, 1959 [Oct. 25, 1958], No. 36122/59. Class 97 (1). [Also in Groups XIX, XXIV and XL (b)] In an optical system for a photo-electric arrangement (see Group XL (b)) light from lamp 3 passes through aperture 5 in mirror 6 to impinge on concave mirror 2 fixed to rotating shaft 1. As shaft 1 rotates, beam 8 describes a cone and is caused substantially to retrace its path by reflex reflector 9. Slight displacement introduced at reflector 9 causes the beam to be reflected from mirror 6 to photo-cell 11. In modifications, mirror 2 may be replaced by three mirrors forming a pyramid and reflector 9 by a comer reflector on an instrument pointer.

Title: Speed-measuring system
IPC: B61L17/00
Filed: 1956-11-27
Abstract: 818,782. Speed measurement. FORGES ET ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE JEUMONT. Nov. 27, 1956 [Dec. 30, 1955; March 7, 1956], No. 36213/56. Class 40(1). [Also in Group XXX] The speed of movement of a body of ferro-magnetic material relative to another object (where the body is a track on which the object moves or a frame in which the body rotates) is measured by impressing a succession of magnetic marks on the body and sensing these marks by suitable responsive .means, each mark being made as a result of the pick-up of a signal by the responsive means. In Fig. 1, the recording head 4 makes a mark on a railway track 2 which is picked up by the reproducing head 5 when it has travelled the distance m. The receiver 9 detects this signal and passes an impulse to the oscillator 8 to cause a fresh mark to be made. The indicator 11 measures the frequency of the signals and thus gives a speed of the vehicle relative to the track. A further oscillator 12 continuously generates signals of very low frequency (e.g. 1 c/s) the failure of which de-energizes relay 14 and indicates a fault. These signals also initiate the generation of the marks. Erase heads 6, 7 prevent false pick-up due to stray magnetization of the track. The indicator may be used to control signals, automatic safety devices or speed-regulating means. The indicator 11 may show the mean amplitude of the pulses. When the direction of travel of the vehicle is reversed the connections to heads 4, 5 are interchanged. For measuring the speed of rotation of an object (Fig. 2), the magnetizing head 4A, pickup head 5A and erase head 6A are mounted on a removable non-magnetic yoke 20 and can move radially in sleeves 21, 22, 23. The rotor may be a flywheel, disc, shaft or ring, and if non- magnetic it may be coated, or there may be attached a ring or disc of iron. A plurality of erase heads can be used.
