Title: Method and apparatus for making a strip of fasteners
IPC: F16B/
Filed: 1974-08-05
Abstract: 1472751 Apparatus for making strips of nut fasteners TOLWOOD MULTIFASTENERS Ltd 5 Aug 1974 [3 Aug 1973] 36989/73 Addition to 1358099 Heading B3A A method of forming a strip of fasteners, pre-orientated for installation in a panel, comprises forming a continuous strip of metal having a cross-section conforming to the desired fastener cross-section, separating the fasteners from the continuous strip, and subsequently joining the separated fasteners in orientated serial alignment by attaching at least one elongate metal strip to each fastener by a fused metal to metal bond. Multi-threaded piercing fasteners or nut fasteners, which have been separated from a continuous strip of metal having a cross-section conforming to the desired fastener cross-section, are fed down a shoot 30, Fig. 2, on to a guideway 31. Radial members 33 of a rotatable disc 32 enter the threaded bores 25, Fig. 1, of the fasteners to advance them along the guideway. Metal strips 27, 28 are laid on the surfaces 13 of the fasteners by a roller 56 and are fed from two reels 54, 55. A ratchet wheel attached to the disc 32 is engageable by a pawl 36 having a pivot 40 mounted eccentric to the axis of a cam 41. Motion of the cam provide the initiation of the advancement of the fasteners and the bonding of the strips to the fasteners by electrodes 44, 45. Each electrode is supported by a pneumatic piston and cylinder assembly controlled by a valve 51 which is actuated by a cam follower 52. A non-return pawl 57 engages the ratchet wheel 35 and disc 32 to retain the fasteners against displacement towards the shoot. The electrodes are connected to a source of electrical current and spot weld the strip to each fastener. Advance of the fasteners along the guideway 31 causes the strips 27, 28 to advance and unwind from the reels 54, 55. The fasteners welded to the strips 27, 28 pass beneath a guide roller prior to winding on to a reel 60. When a reel is filled then a junction between adjacent fasteners is severed. The fasteners can then be assembled in a panel using a punch. In an alternative embodiment, Fig. 3 (not shown), grooves (62) are provided in the surface (63) of the fastener to receive the strips 27, 28 to prior effecting the bond.  Continuous welding of the strips to the fasteners may be performed and soldering and brazing methods can be used instead of spot welding.

The characters on a type-bearing drum are arranged to compensate for movement of continuously fed recording medium during rotation of the type-bearing drum. Each character 2 is in one of a plurality of overlapping panels 12 of uniform size, the position of each character in its panel being displaced a distance #l, in the direction of rotation of the drum, with respect to the preceding character. The overlap between the panel of one character and the preceding panel is by the amount of the smaller of the spaces between the character and the boundaries of the panel. The type-bearing drum may be used for printing on photosensitive recording medium, the characters being transparent, and light being selectively transmitted to a window (6, Fig. 1) by optical fibres (5). The windows are of the same size as the panels 12. Alternatively, the type-bearing drum may be used in electrographic printing, the characters being in relief, and electrodes (8, Fig. 2) of the size of a panel 12 being provided.

Abstract: 1454931 Dealing cards F PIC 27 Aug 1974 [28 Aug 1973] 37424/74 Heading A6H [Also in Division B8] An automatic card dealing machine comprises a stand 1, Fig. 1, including a fixed gear wheel 3, Figs. 1 and 2, carrying a pivot 2 on which is rotatable a stage 5 carrying a toothed ring 6, the stage being rotated by a motor M carried by the stand 1 and rotating a gear wheel 4 engaging the ring 6. The stage carries two slide members 14 supporting the front part of a pile of cards. The stage supports a gear wheel 7 engaging the wheel 8, so that as the stage rotates the wheel 7 is rotated and rotates a crank arm 8, whereby a shuttle member 9 is reciprocated towards and away from the members 14. The member 9 supports the rear part of the pile and carries an impeller 12 which separates one or more cards from the pile and ejects them, so that one or more cards are ejected at each of a plurality of locations as the stage rotates. The pile is weighted by an element 15 which carries a device 21 which blocks the return of the member 9 after the last card has been ejected. The stand 1 is capable of slight rotation on a base 16, and when such rotation is manually produced, a stop 17 on the base engages a switch 18 to start rotation, while when the device 21 blocks the shuttle, the motor causes reverse rotation of the stand on the base to stop the motor. In another form, the stop is carried by the wheel 3 and the switch engaged thereby is mounted on the base 16. The number of cards ejected is controlled by adjusting the impeller 12 and by adjusting the height of a plate 13 by means of a roller 23.

Abstract: 1,020,234. Metallurgical converters; removing waste products in industrial processes. YAWATA IRON & STEEL CO. Ltd., and KOKOYAMA ENGINEERING CO. Ltd. Oct. 10, 1962 [Oct. 17, 1961], No. 38373/62. Headings F4B and F4X. In an emergency in the operation of a metallurgical converter 1 from which waste gases are recovered as unburnt, such as the failure of the electric supply to blowers, pumps, meters &c. in the waste gas recovery system, blowing is stopped and the lance 4 withdrawn and nitrogen is injected from a main pipe 3 into the gap between the converter mouth and the entry 5 to the waste gas recovery system so that nitrogen is interposed between the waste gas in the recovery system and air which subsequently enters. At the same time as the injection from the main pipe 3, nitrogen is injected into the recovery system through auxiliary pipes at locations 3<SP>1</SP>. During normal operation a nitrogen curtain 2 is formed round the mouth of the converter and is maintained during the emergency operation. During normal operation a blower 9 draws waste gases through a waste heat boiler 6 and a dust removing device 7 and passes it to a gas holder 10, a three-way valve 11 being operable to discharge the waste gas to atmosphere if its composition is not appropriate for collection. In the emergency operation the valve 11 is operated to discharge the waste gas to atmosphere and if the electric supply to the blower 9 has failed the residual rotary momentum of the blower is utilized to exhaust the gases to atmosphere.

Title: Improvements in or relating to apparatus for and methods of toughening glass articles
IPC: C03B27/048
Filed: 1963-10-02
Abstract: A method of toughening glass articles comprises exposing a heated glass article to the action of a plurality of annular divergent jets of a gaseous chilling medium and controlling the pressure of gas within the areas surrounded by the jets independently of the pressure within the jets. Preferably the heated article, for example a glass sheet 12, is placed between opposing pairs of annular orifices 8. The orifices are formed by convergent inner cones 5 and outer cones 4 separated by struts thus giving a passage 7 which forms a divergent stream of gas. In order to differentially toughen a heated glass article the aperture 22 within the annular orifice is connected to means 20, 21 for supplying a gaseous chilling fluid at a different pressure from that delivered through the annular orifice; and the aperture 22 may be connected either to a supply of gas at a lower pressure than that supplied through the annular orifice or to an exhaust means so that during the quenching operation control of the differential toughening of the said article is effected. Preferably the exhaust means is applied after <PICT:1107265/C1/1> <PICT:1107265/C1/2> the lower pressure gas when a glass sheet, for example, reaches its strain point.  The method is particularly useful in the differential toughening of curved windscreens.  Here a curved heated sheet 23 is placed between a pair of opposed quenching frames 17 containing a plurality of cooling nozzles.  The nozzles 13 in the central area are identical with those described above to differentially toughen that area, but those nozzles 24 on the periphery are ordinary aperture nozzles.
