Abstract: 756,343. Counting-apparatus. BRECKNELL, DOLMAN & ROGERS, Ltd., [formerly BRECKNELL, MUNRO & ROGERS, Ltd.], and DOLMAN, H. J. July 13, 1954 [April 22, 1953], No. 11064/53. Class 106 (1). [Also in Groups XVII and XVIII] A cabinet for storing and dispensing packets of cigarettes is provided with magazines 2A ... 2D containing packets of twenty and magazines 3A ... 3D containing packets of ten, the packets being introduced through a top cover 4 secured by a lock 4A and withdrawn by sliding drawers 5A ... 5D and 6A ... 6D associated with the respective magazines. On the underside of each drawer a rack 7 co-operates in known manner with a pawl 7A to prevent closing of a partly open drawer, and with a line of shift bars 8 to ensure that the drawers can only be opened one at a time. Beneath the drawers 6 are pivoted latches 9 having cam tracks 10 of half the length of similar cam tracks 11 on latches 12,- which are pivoted beneath the drawers 5. When a drawer is pulled open, a pin 15 on the bottom of the drawer co-operates with a cam track 10 or 11 to swing the associated latch and through a peg 13 move a common counter-operating bar 14, a latch 12 imparting double the movement imparted by a latch 9. Four locks A1 ... A4 allow four persons access to the magazines, and when a key is inserted a cam 16 is turned to lift a peg 17 on a member 18 pivoted at 19, and through a tail portion 20 to operate a drawer release bar 21. Movement of the bar 21 moves an arm 26 of a bell crank lever 23 out of engagement with a stop 14A on the bar 14 to allow movement of the bar 14 when a drawer is opened. For recording the sale, each member 18 carries a counter B, corresponding to each lock, provided with rockable arms 29 which when a lock is operated enter a notch 30 in the bar 14, additional notches 31 being provided for those drawers which deliver packets of twenty cigarettes. Movement of the bar 14 causes the notches 30, 31 to deflect the arm 29 to operate the counter. Slidable cash tills C1 ... C4 are provided which can be opened only when the appropriate lock is operated.

Filed: 1965-03-16
Abstract: 1,067,921. Continuous-casting machines; applying mould-linings. SOUTHWIRE CO. March 16, 1965 [Sept. 4, 1964], No. 11084/65. Heading B3F. To retard transfer of heat from cast metal to a mould, comprising a casting groove (11) closed by a belt (12), a thermal barrier, e.g. a layer of soot is applied to the mould interior. Gas burners (20, 30) are mounted adjacent a belt (12), Figs. 1, 2 (not shown), and the groove (11) of a copper wheel (10), Figs. 3, 4 (not shown), of a continuous casting machine. Soot produced by the incomplete combustion of acetylene is directed by shields (26, 28) and (36, 38) to form layers (50, 51) on the belt and wheel respectively. The layer is said to aid parting of the metal from the mould and to prevent mould deterioration and segregation of alloy constituents, e.g. from cast copper. The burners (20, 30) are supported from the support block (19) of the extractor shoe (18). There are valves (23, 33) to adjust the gas flow in relation to the mould speed and a nozzle (40) for water to cool the wheel inner surface to aid soot deposition.

Title: Improvements in and relating to weighing machines
IPC: G01G13/00
Filed: 1926-04-27
Abstract: 251,305. Lefevre, C. D. April 27, 1925, [Convention date]. Automatic - feed weighers.-An automaticieed weigher comprises a weigh-hopper having a discharge-gate at its base, a container disposed above the hopper and provided with feed and discharge gates, means whereby an opening movement of the discharge-gate of the container causes the closing of its feed-gate and the opening of the discharge gate of the hopper, and a movable stop adapted to limit the opening movement of the discharge gate of the container so as to prevent discharge therethrough until the discharge gate of the hopper is closed. The weighings obtained are totalled by a recording device. As shown, a hopper 35 is supported upon a weigh-beam 37, which is connected through a draw-rod 42 to a weighing-apparatus and a recording and totalizing device. The hopper is open at the top and is provided at its base with a pivoted discharge gate 43 adapted to be closed by a counterweight 49 and to be held in closed position by toggle-levers 52, 53. A container 1 is disposed above and is adapted to discharge into the hopper 35. The container is provided with slidable feed-gates mounted on racks 20, 21 engaged by toothed sectors 18, 19 and normally held in closed position by a spring 34. Two pivoted discharge-gates 4, 5 connected by a pin 80 and slot 81 are pivoted to the base of the container, and are provided' with counter-weights 12, 13 which normally hold the gates in closed position against the edges 6, 7 of the container. A cam 29 depending from the sector 19 is normally engaged by a roller 29 on the gate 5, which roller is also adapted to engage the upper end of a stop member 66 pivoted on a pin 67. At the commencement of an operation, the dischargegates 4, 5 and 43 are closed, the feed-gates are open and the hopper is charged with material. Material flows into the container until the weights 12, 13 are counterbalanced and the gates 4, 5 rotate into the position shown, in which position they are held by the strip 66. The movement of the gate 5 allows the feed-gates to close, and also through a link 71 causes a lever 69 to trip a spring-controlled bell-crank lever 59<a>, 59<b> which in turn trips the toggle-levers 52, 53 and allows the gate 43 to open. After the discharge from the hopper, the gate 43 closes and a cam 65 on the lever 53 strikes a lever 64, thus tripping the stop 66 and allowing the gates 4. 5 to open. The gates 4, 5 are returned by the weights 12, 13 and the operation is repeated.

Inventor: THARALDSEN FILIP
IPC: C22B4/04
Filed: 1916-08-07
Abstract: 108,363. Tharaldsen, F. Aug. 7, 1916. Electrode furnaces.-An ore of zinc or other volatile metal is continually introduced into a furnace as a fairly thin layer, which is heated by radiation so that the metal can escape to a condenser. The layer is horizontal or approximately so; for instance it may be slightly concave or convex. In the furnace shown, a heating-chamber a is arranged between two charging chambers b A long hearth c common to all the chambers is constructed to run on rails, and is separated by narrow gaps from the partitions a" and parallel end walls of the furnace. Ore mixture is fed from hoppers e into the chambers b alternately, and is spread in a layer by the partitions as the hearth travels to and fro. Residues are removed bv rakes k from the chambers b between successive charging operations. Overlapping flanges C<1> on the hearth and side walls of the furnace, in conjunction with the charge, prevent escape of vapours except through a pipe f to the condenser. An arc or arcs may be prcduced by direct current or alternating current of one or more phases, between two or more vertical and inclined electrodes d. When the materials are not liable to produce dust, the outer chambers may be dispensed with, charging being effected, as before, outside the reduction chamber. The magnetic field produced by the current may deflect the arc downwards. In modifications, chambers may be arranged in a circle above a rotary hearth: or several series of chambers may be arranged above a long straight hearth.

Title: Improvements in or relating to pipe couplings
IPC: F16L29/04
Filed: 1957-04-08
Abstract: 832,705. Pipe couplings. AEROQUIP CORPORATION. April 8, 1957 [Jan. 31, 1957], No. 11443/57. Class 99(1). Couplings A and B having self-closing valves 32, 84 respectively are connected by means including a sleeve 50 which is rotated against spring action until it reaches a position where locking is effected and the valves fully open. Coupling A.-Fixed to a hollow cylindrical part 10 is a member 16 having external quick action screw threads 18 and a flat sided flange 27. A movable valve has a face 32 which engages a corresponding surface 30 within the part 16 and has a sleeve part 34 which engages the bore of the part 10, the valve being urged to a closed position by a coil spring 40 which is engaged at one end by a shoulder 42 in the part 10 and by an abutment 44 in the valve at the other end. An o-ring 46 provides a seal between the valve head and the interior of the part 16 in which it is contained in a recess. Coupling B.-Sleeve 50 contains a member 48 which has internal screw threads 52 to engage the screw threads 18 and an external recess 58 in which engages a pin 60 carried by the sleeve. The pin permits axial travel of the part 48 within the sleeve, the movement being limited by a flange 62, a spring 64 being inserted between the parts 48 and sleeve 50 to urge the flange 62 against the pin 60. The outer end of sleeve 50 is formed with a recess which corresponds to the flange 27 on coupling A which effects locking engagement on mating. A sleeve part 70 is secured in the member 48 by a flange 72 at one end and a clip 74 at the other and which houses a valve with a bevelled head 84 enclosed in a sleeve 88 and secured to the part 70. The sleeve 88 has a bevelled interior end surface 90 to correspond with the valve head and is slidably mounted on the stem portion 78, a coil spring 94 urging the sleeve 88 to the valve head position so that it remains closed. Operation.-The sleeve 50 of coupling B is advanced on coupling A and as the screw threads are engaged, the seal ring 46 becomes effective. The valves have ports in their bevelled surfaces which remain closed by spring action until the valves are unseated. Rotation of sleeve 50 causes the part 48 to engage the part 16 and the valves which are face-to-face move to the left and further compress spring 40. Release of the sleeve 50 will cause the couplings to unscrew and fall apart under pressure of the springs. Continued rotation of the sleeve will eventually bring the recess 68 into mating relation with flange 27 when the compressed spring 64 causes the sleeve 50 to spring to fully engage the recess and flange and the couplings are locked together. The number of leads on the screw threads 18, 52 should equal the number of flats in recess 68 and on flange 27, e.g. if there are six-screw-thread leads and six flats, there will be six locking mating positions. Specification 656,483 is referred to.
