IPC: D05B35/06
Filed: 1963-01-12
Abstract: 992,456. Sewing machines. KAYSER BONDOR Ltd. Jan 8, 1964 [Jan. 12, 1963], No. 1481/63. Heading D1G. A machine for sewing on patches comprises means for feeding a predetermined length of tape, means for severing said length from the remainder, and means for delivering said length in a folded condition to a work-holding clamp adjacent the needle. A sewing machine 1 is provided with a clamp feed having a lower jaw 3 and an upper jaw 6 adapted to form a U-shaped line 55 of stitching to secure a folded patch 54, cut from a tape 9, over the rolled end of a pair of members 52 for covering thereat the protuberant seam 53 interconnecting the latter. Tape 9 is fed by means mounted on a plate 14 slidable transversely in guides 15. The tape first passes through a guide 37, then between serrated wheels 38 and the serrated end of a shaft 29, and finally beneath an upwardly spring-biased blade 36. The wheels 38 are carried by a shaft 40 journalled in arms 39 which are pivoted to plate 14. The distance between wheels 38 and shaft 29 is adjustable by means of screws 41 extending through arms 39 and engaging plate 14. Shaft 29 is driven intermittently via a uni-directional clutch 30 by a gear pinion meshing with a gear sector 26 oscillated by a link 27. A lever 20, pivoted at 21, is coupled at one end to plate 14 and at the other end to a pair of opposed solenoids 22, energization of one or the other of which thereby serves to shift plate 14 to one side or the other. A pair of pivoted arms 34 carry between their free ends a heated wire 25. One arm 34 is engaged between collars on a shaft 33 which is slidable in plate 14 and is coupled to one end of a linkage 13, the other end of which co-operates with a cam 12 on a shaft 10. A pair of arms 8, rigid with shaft 10, carry at their free ends a bar 79. A sprocket wheel 11 or shaft 10 is connected by a chain 51 to the piston of a pneumatic jack which is normally positioned to maintain wire 25 above plate 14 and bar 79 rearwardly of the jaws 3, 6. After a length of tape has been fed beneath the blade 36, and the jaws 3, 6 being open, a pedal is depressed to effect movement of the jack piston to its other end position and also energization of a solenoid controlling an arm 35. The latter thus engages blade 36 to clamp the tape against plate 14, and wire 25 engages the tape at a position 43 to sever a patch length 54 therefrom. Bar 79, which is rendered adhesive, then engages patch length 54 at a position 44. During the return stroke of the jack piston, bar 79 carries patch length 54 within the jaws 3, 6 in folded U-shape formation. The seam 53 at the rolled end of members 52 is inserted into the folded patch 54 and stitching is commenced. Plate 14 is shifted in accordance with the line of stitching by actuation of a microswitch effected by movement of the work-feed clamp.

Abstract: 641,212. Luminescent materials. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). Jan. 19, 1945, No. 1603. [Class 39 (i)] A phosphor comprises a matrix which is a zirconate of strontium, barium or cadmium activated with 1 per cent or less of silver, copper or praseodymium. A volatile flux such as aluminium fluoride nr a non-volatile flux such as lead monoxide can be used in the preparation of the phosphor. According to one example a phosphor is prepared by dry-mixing zirconium dioxide, strontium sulphate and lead monoxide, adding bismuth nitrate in aqueous solution to form a slurry, mixing until uniform, heating to evaporate off the water, grinding the dry batch so obtained to pass a 100-mesh screen, firing at 1200-1300‹ C. until the evolution of sulphurous gas ceases, quenching suddenly in water, and finally drying and regrinding the batch to pass a 100-mesh screen. The phosphor is excited most powerfully by ultraviolet radiation of about 3000 Š to 3800Š, especially 3650 Š, although also excited in some degree by the 2537 Š resonance radiation of mercury. A layer of the phosphor may be coated on the inner surface of the enclosing jacket of a high-pressure mercury vapour lamp or on a sign or dial exposed to the radiation from such a lamp, especially for use in darkness. Specification 460,210, [Group XXIII], is referred to.

Filed: 1920-01-19
Abstract: 162,054. Boonzaier, W. G. Jan. 19,1920. Addition to 147,963. Couplings, automatic.-In an automatic coupling as described in the parent Specification, a modified form of link raising and locking device comprises two arms formed of bent plate which are secured to a transverse shaft and protrude under the link, the transverse shaft being locked in the raised position either by means of a pawl engaging the bent end of the rod or by means of a transverse link suspended bar engaging a slot in a quadrant attached to the bent arm. The handle 15a of the transverse shaft 15, Figs. 3 and 7, works in a slot 59 in a bracket 58 which is attached to the side of the vehicle, link-lifting arms 65 being secured to the shaft 15 and so placed that they come under the link hook of the coupling. A pawl having two oppositely-turned hooks 64, 60a is pivoted to the bracket so that either the upper or lower part projects over the slot 59. Fig. 3 shows the handle lifted clear of the locked position in the hook 64, the pawl falling backwards. A lug 62 on the pawl protrudes over the slot and in falling the handle 15a strikes this lug and restores the pawl to the position for automatically locking the handle when it is next raised. A pin 63 attached to the pawl prevents it from being thrown backwards when the handle is at the bottom of the slot. Figs. 9 and 13 show an alternative method of locking the transverse shaft. Each bent arm 15<a> has a quadrant 67 working in a vertical guide 68, a notch 69 being cut in the quadrant. A transverse bent bar 71 is suspended by links 72, and works at right-angles to the quadrant. When the arm 15<a> is raised, the notch 69 comes opposite the end of the bar 71, which swings into it and locks the transverse shaft 15. Unlocking is carried out by pulling the arms 75 or 76 which raises the bar 71 clear of the notches 69.
