Title: Portable Apparatus for Splicing Synthetic Yarn
Inventor: WILLIAMS WILLIE VINCENT
IPC: B65H69/08
Filed: 1967-01-23
Abstract: 1,165,261. Spinning yarns. W. V. WILLIAMS. 23 Jan., 1967 [14 Nov., 1966], No. 3398/67. Headings D1F and D1W. A pistol-grip hand-tool for splicing thermoplastic synthetic yarn comprises a radiant heater towards which (but never touching) the ends to be fused together are gradually moved by a trigger-operated ratcheting mechanism. When the trigger 38 is in released position, a carriage plate 36 urged by spring 40 is in its most advanced position, head portion 44 engages the back of a slide 48 urged by a spring 52 against a stop 53, coacting jaws 63 and 65 are fully separated with a yarn receiving slot 64 well in advance of electric heating element 32 and adjacent the forward end of cover slot 104, a switch-actuator rod 57 is free from contact with lug 56, microswitch 27 is normally open to interrupt the circuit between a battery 22 and element 32. Yam ends to be spliced are passed through a slot 103 and enter slot 64. Trigger 38 is fully retracted to a position whereat plate 36 engages stop 55 so that spring 40 is fully stretched and jaws 65 and 63 engage to cause slide 48 to move backwards and expand spring 52, during which movement rod 57 is held in the switch closing position and element 32 is energised. The jaws and ends clamped therebetween are then shifted adjacent to the element 32, although, upon the initial full retraction of the trigger, rail 43 and the jaws are still spaced laterally from the element. In preparation for subsequent gradual movement of the jaws by ratcheting mechanism towards a position whereat the desired fusion is effected, as the trigger and plate 36 approach the end of the initial retraction a link 91 is shifted rearwardly against the force of a spring 84 to disengage a front pawl 78 from ratchet bar 69 and engage a back pawl therewith. The action of a tooth on the pawl shifts bar 69, and, in consequence, the rail 43 and jaws 63, 65, one step laterally towards the element 32. The trigger 38 and plate 36 are then reciprocated a slight amount only (to operate the ratchet mechanism through alternate engagement of front and back pawls) thus keeping the jaws in the vicinity of element 32 and moving ever closer thereto without actually making contact therewith, this being ensured by an adjustable stop 106. Fusing and splicing having been accomplished, the trigger is released and the apparatus parts, actuated by a resetting cam 67, return to normal (release) condition in which the spliced may be removed.

Title: Improvements in and relating to the grinding of gear wheel bores
IPC: B24B41/06
Filed: 1956-02-06
Abstract: 790,880. Grinding. MULLER, W. Feb. 6, 1956 [Feb. 19, 1955], No. 3644/56. Class 60. [Also in Group XXII] Means for inserting a gear wheel 6 which is to be ground with a central bore into a rotary chuck provided with clamping rollers 3 for engaging between the teeth of the gear wheel comprises a holder 11 adapted to be moved axially to push the gear wheel into the chuck and an annular diaphragm 8 mounted on the front of the chuck so that an inwardly-projecting tooth 10 carried by it is disposed in line with one of the rollers, the arrangement being such that, should the gear wheel not be located on the holder so that the rollers 3 would engage between the teeth, it will contact the tooth 10 as it is advanced and thereby be rotated to the extent necessary to position it correctly. The rollers 3 are loosely mounted on pins 2 so that they can be urged into clamping engagement with the gear wheel by segments 5 urged inwardly by jaws 4. The holder 11 for the gear wheel is mounted in a housing 16 which is slidable axially in an arm 17 arranged to be swung from a loading position to that shown in which it is in line with the chuck ; the shank of the holder 11 has a screw-threaded engagement 12 with a sleeve 13 in the housing 16 and is urged outwardly by a spring 14. With the arm in this position, axial advance of the housing by an arm 19 results in the gear wheel being inserted in the chuck provided the tooth spaces of the gear wheel are aligned with the rollers 3. If, however, this alignment does not occur, one of the gear teeth will contact the tooth 10 and, as the housing 16 then continues to advance, the holder 11 will be forced back against the action of the spring 14 and so rotate in the threaded sleeve 13 sufficiently to align the spaces between the gear teeth with the rollers 3 ; the spring 14 will then advance the gear wheel into the chuck. The tooth 10 is of tapered form and its rear side is somewhat broader than the adjacent front side of the corresponding clamping roller 3. Withdrawal of the rollers 3 from the pins 2 is prevented by providing inwardly-directed teeth 10<SP>1</SP>, which are less wide than the tooth 10, on the diaphragm in alignment with the rollers 3 or by means of set screws inserted in the ends of the rollers.

Title: Improvements in or relating to power operating mechanism applicable, for example, to electric switchgear
IPC: H01H33/30
Filed: 1939-02-06
Abstract: 524,729. Actuation of switches. GENERAL ELECTRIC CO., Ltd., and GARRARD, C. J. O. Feb. 6, 1939, No. 3873. [Class 38 (v)] A fluid-pressure operating mechanism, stated to be of general application, is shown in its application to a circuit-breaker, the movable contact of which is closed and opened by upward and downward movement, respectively, of a piston 3. To open, valve 9 is opened by hand or electromagnetically whereby piston 3 descends expelling fluid from beneath it to atmosphere by way of port L in valve 12. When about half the stroke is completed, valve 12 which, with valve 11, is driven from the contact mechanism, changes over and the fluid can only be expelled through a needle valve NV in the valve 10. Then, or shortly after, valve 11 changes over, cutting off the fluid-supply from reservoir 2 and allowing inertia and the expansion of fluid in the cylinder to complete the stroke. To close, the valve 10 is opened by hand or electromagnet'cally, and an analogous series of operations takes place. If the breaker closes on to a fault, the state of valve 12 permits instant reopening the moment valve 9 is opened by the overload relay, but an interlock may be provided' to ensure closure of valve 10 when 9 is thus opened.

Title: Improvements in the utilisation of the heat of combustion of pyrites in the manufacture of sulphuric acid by the chamber process
IPC: C01B17/84
Filed: 1938-02-09
Abstract: The heat of combustion of pyrites is utilized in the manufacture of sulphuric acid by the chamber process by roasting the pyrites with a regulated quantity of air in a furnace in which very rapid oxidation is obtained by causing small particles of pyrites to move freely in gases while burning, and passing the gases obtained through a dust collector resistant to heat and corrosion and adapted to avoid dissipation of heat, so as to yield gases substantially free from suspended solid matter and carrying not less than 55 per cent of the heat of combustion of the pyrites.  The dust collector may be of the impact type in which the gases come into contact with surfaces of firebrick &c., of the type in which gases pass through porous beds of refractory material, or of the cyclone type.  Preferably, a cyclone dust collector built or lined with firebrick &c., is built integrally with the furnace the whole being insulated together.  The air admitted to the furnace may be regulated to produce a gas containing more than 9 per cent of sulphur dioxide.  The heat of the gases may be utilized to denitrate the acid in the Glover tower and/or to concentrate the sulphuric acid to 94 per cent. Arsenic may be removed from the hot gases by means of iron oxide. A chart is furnished whereby the percentage of the heat of combustion of the pyrites carried by the gases can be obtained if their temperature and percentage content of sulphur dioxide are known.
