Title: Device for tying coils of wire
IPC: B65B27/06
Filed: 1973-04-11
Abstract: 1398482 Twisting wires together H ELINEAU 11 April 1973 [23 May 1972] 17469/73 Heading B3E [Also in Division B8] Apparatus for tying coils of wire comprises means for placing tie-wire elements along the inner and outer surfaces of the coil, and means for twisting the elements ends together comprising a member having a head for receiving the two ends and movable in translation and rotation, and a backing-plate opposed to the head and acting to restrain displacement of the wire during rotation of the member. The coil 6, Fig. 3, is conveyed on a hook to a compacting and tying station where it is supported on bars parallel to its axis which are raised to take the weight of the coil, though the hook remains in position. The coil is compacted by axial pressure, Fig. 1 (not shown), and readjusted in height so that it is correctly aligned with two pairs of arms 13 (one pair shown, Fig. 3) spaced at 90 degree intervals around its periphery and pivoted at 11 to a carriage 15 slidable by a first hydraulic jack (not shown) on a fixed rod 17. The arms are pivotable by rods 22 connected to a further carriage 23 slidable by a second hydraulic jack (not shown) on a sleeve 16 of the carriage 15. At the beginning of a cycle, the arms 13 are pivoted together so that their ends cross, and the ends of wires 24 are gripped by grippers (not shown) on the ends of the arms. The arms are then separated as shown by operation of the second jack to cross the wires on the near side of the coil, Fig. 10, and the first jack is operated to pass the arms one outside and one through the coil drawing the wires with them, and then the second jack is operated to close the arms together and cross the wires on the far side of the coil (see Fig. 5, not shown). At each of the eight crossing points a twisting device is then made operative, Fig. 6. A twisting member 27 is mounted for rotary and longitudinal movement, and is keyed to a pinion 42 on arm 48 meshing with a sun gear 39, the arm and sun gear being fixed and rotatable respectively on a sleeve 43 slidable on fixed shaft 41 by jack 51. When the jack is operated to advance the twisting member 27 to engage the crossed wires, shoulder 37, spring 55, and plate 54 rotate levers 52 on fixed pins 53 to bring together the two halves 28a of a backing plate 28, see Fig. 13, so that two offset grooves 58 are formed engaging the crossed wires. The end of the head of twisting member 27 is shown in Figs. 10 and 11, and includes a central aperture 61, grooves 57 receiving the crossed wires, and recesses 62 flanked by shear members 63 co-operating with fixed shear members 64. When the twisting members 27 and backing- plates 28 are in position, gear 39 is rotated to effect twisting of the sheared wire ends to form knots within the apertures 61, the knots having the free wire ends turned down. The twisting elements are then withdrawn, the arms 13 returned to their initial positions, and the coil supporting bars lowered to suspend the tied coil on the hook.

Filed: 1972-04-17
Abstract: 1359254 Embossed card reader; character recognition AMP Inc 17 April 1972 [18 May 1971] 17557/72 Headings G4M and G4R A reader for embossed cards is arranged so that raised regions on the card prevent light from being reflected from a source to a detector. A card is inserted in a slot into a card carrier having a spring-loaded back-plate 82. The lower edge of embossed characters are aligned with a knife-edge portion 78 on a front plate of the carriar and the carrier is depressed until recess 68 is engaged by spring-loaded arm 72, to locate the characters in a desired position. The carrier is coupled to a band 12 driven by a motor 10. When the carrier is depressed a switch 44 is operated and operation of an external start switch causes the carrier to be driven to a leftmost position where it operates a reverse switch and is then driven back to the start position. The carrier contains a cam arranged to operate a switch controlling a light source so that the light is only on for the desired read period. The read head 3 is flexibly mounted on arms 92, 94 coupled to a mounting adjustable in height. The head contains a light source 28 and a sensor 30. The front face 98 of the head contacts the embossments 80 on the card 1 and fibre light guides 36, 37 from the lamp and sensors terminate in the front face. The embossment prevents light from being reflected from the lamp to the sensors. On return to the start position a switch is operated and the card is ejected.

The frame of each filter element is formed by a pipe 9, Fig. 4, the ends of which pass through the headpiece 1 and are provided with cocks 11, 12. The cloth walls 20, 21, Fig. 5, of the element and the supporting gauges 22 are held apart by corrugated plates 18, 19, the corrugations being vertical and providing passages for the free flow of filtrate through apertures 9b into the pipe 9 for discharge through the cocks 11, 12. Plates with ribs 24, Fig. 7, may replace the corrugated plates. The material under treatment is forced in through a conduit 16 on the head-piece 1. Cakes forming on the elements can be dried by means of compressed air or steam supplied to the chamber outside the elements and the cakes can be dislodged by means of compressed air supplied to the pipes 9 from a header 36. Connections may be made so that the header can be placed in communication with the atmosphere to give alternating periods of released pressure. Alternatively the cakes may be removed from the filter elements by brushes 29, arranged between the elements and carried by a member 30 which slides longitudinally on the bottom of the casing 5. A sludge receiver 26 is provided beneath the filter chamber and communicates with it bv conduits 25. The casing 5 is normally secured to the head piece 1 by clamps 7 but it can be moved on rails 3 to the position shown by dot-and-dash lines, Fig. 1. The filter elements are connected and spaced at the end by a transverse member provided with rollers 14, which engage rails 15 on the inside of the casing.

Title: A process for vaporizing sulfur or for producing sulfur derivatives
IPC: C01B31/26
Filed: 1948-06-30
Abstract: Sulphur vapour is continuously produced by passing a stream of molten or powdered solid sulphur directly into a mass of hot suspended non-volatile solids, e.g. silica, pumice, broken fine brick, slags, pyrites or bauxite, maintained at a temperature above the boiling point of sulphur, whereby the sulphur becomes immediately vaporized. By employing finely-divided carbon or metals as the solid, carbon disulphide or metallic sulphides may p  be obtained directly.  As applied to the production of carbon disulphide, powdered sulphur is introduced through a line 15, liquified in a heat-exchanger 14 and is introduced through a line 16 into the lower zone B of a reactor. Powdered <PICT:0644537/III/1> coke is fed through a double bell valve 29 into a chamber 5 where it is fluidized by air from a pipe 6.  The suspended coke passes through pipes 8 and 9, and is partially burnt in a zone A by preheated air supplied through a pipe 10.  The suspended coke, having a temperature of 1100-2000 DEG  F., passes downwardly in fluidized form through the zones B via pipes 18a, 18b and 18c in counter-current to sulphur vapour which is immediately produced from the liquid sulphur in the lowest zone B and ascends progressively enriched with carbon disulphide through grids 17b and 17a.  Carbon disulphide vapour leaves through a pipe 19, passes through a dust separator 20 and is condensed in a cooler 21.  Excess of hot unreacted carbon passes via a pipe 18d into a zone C and is recirculated in fluidized form through pipes 25, 281, 10 and 9 with the aid of air from a line 23.  A portion of material is periodically withdrawn through a pipe 26 to prevent an accumulation of ash. Contamination of the coke entering upper zone B with air &c. is prevented by an inert purging gas entering through a line 30, and loss of sulphur &c. with the carbon entering zone C is prevented by an inert purging gas entering through a line 31.  According to another embodiment, liquid sulphur and hot fluidized carbon are mixed in a line of restricted cross-section, the mixture passing upwardly through an expanded conical distributor into the bottom of a reaction vessel.
