Title: Improvements in or relating to High Pressure Metal Vapour Electric Discharge Lamps
Inventor: DIXON ANGUS
IPC: H01J61/54
Filed: 1966-01-12
Abstract: 1,165,724. Discharge lamps. GENERAL ELECTRIC & ENGLISH ELECTRIC COMPANIES Ltd. 2 Jan., 1967 [12 Jan., 1966], No. 1467/66. Heading H1D. In a double-walled high-pressure metal vapour electric discharge lamp incorporating, between the discharge tube and outer envelope, a thermal starter switch with its contacts shunted across the lamp electrodes and which comprises a snap-acting bimetallic element carrying a movable contact which is normally closed on to a fixed contact andaresistanceheating element which is used to heat the bimetallic element sufficiently to cause the contacts to snap open to initiate the discharge, the arrangement of the switch in the outer envelope is such that the bimetallic element remains sufficiently heated during running up and normal operation of the lamp that the switch contacts remain open, and, in the event of a sudden extinction of the lamp discharge, the switch contacts are delayed from reclosing until the tube has cooled to a temperature at which the filling pressure has decreased to a value when operation of the starter switch can restart the discharge. The resistance heating element may comprise a heating coil disposed adjacent the bimetallic element or may be provided by the bimetallic element itself. The bimetallic element is formed by a preset slightly dished plate to provide the snap action. The discharge tube within the outer envelope has a filling of rare gas and metal vapour at at least 100 mm. of Hg pressure when operating. In an example the filling comprises argon to several mm. of Hg pressure and mercury and sodium, thallium and indium iodides to about 5 atmospheres operating pressure.

Title: Improvements in or relating to coin-freed vending apparatus
IPC: G07F15/06
Filed: 1931-01-16
Abstract: 371,032. Prepayment mechanism for meters. ANDREWS, E. S., 201, Bank Chambers, High Holborn, London.-(Pintsch Akt.-Ges., J.; 71, Andreasstrasse, Berlin.) Jan. 16, 1931, No. 1539. [Class 27.] Mechanism for prepaying basic charges.-In coin-freed apparatus receiving periodical basic payments and continuous payments to obtain release of a commodity, means are provided which allows the collector to remove money from the apparatus only when the mechanism is set to a position which necessitates payment of the basic fee before the apparatus can be further used. A slot q, Fig. 1, receives the continuous payments and a slot g the basic fee coin. After a collection of money, the slot q is closed by a slide a, and the slot g is open, a shutter f therefor, which is pivoted on a shaft 3, being moved away from the slot by the engagement in a slot d of the slide a of an extension e of the shutter. The basic fee coin t, Fig. 3, is inserted through the slot g into a slot in the shaft 3, which is turned, and the coin thrusts against a lug s to move the slide a and uncover the slot q. The slot g is then closed by the shutter f. A spring c is tensioned and bears against a curved portion l of a latch b which locks the slide a by a hook n at one end engaging an abutment m on the slide. A downward extension o of the latch prevents removal of the money-box p by a collector until the latch is released and the slide a is returned to its initial position blocking the slot q. A spring-controlled tumbler h has a downwardly extended portion r which snaps behind the basic fee coin t and prevents its recovery. A portion i of the tumbler, when the slot q is closed, engages behind a lug k on the shutter and so prevents unauthorized pushing back of the slide a by wire inserted through the slot q. Fraudulent actuation of the slide by a wire inserted through the slot g is prevented by the shutter f.

Title: Improvements in machines for feeding and packing pulverulent material
IPC: B65B1/24
Filed: 1926-01-20
Abstract: 259,085. Marks, E. C. R., (Bates Valve Bag Co.). Jan. 20, 1926. Packing pulverulent material into bags or cartons.-Flour &c. falls from a bin or conveyer into a vertical rectangular feed shoot 16, Fig. 4, and is packed in a receptacle on a support 33 by the action of vertically reciprocating members 25, Figs. 4 and 5. Each number comprises a bar 26 with a strengthening rib 32 and carrying a series of wedge-shaped members 27 in spaced relation. The rear wall of each member is flush with the back of the bar 26 and in contact with a wall of the shoot 16, and the side faces 28 abut against wardly and inwardly and meet the lower or packthe side walls. The inner faces 30 slope downing faces 31 at an abrupt angle. The bars are reciprocated in opposite directions until the receptacle is filled and are then automatically stopped with the members 27 opposite and close to each other so that no material can escape while the receptacle is removed and another substituted. The receptacle rests on a table 33 mounted on a. vertically slidable rod 34 normally urged upwards by the action of a weight 45 on a chain 44. The chain co-operates with a sprocket 43 fast with a sprocket 41, the chain 39 of which is attached to a cross-bar 36 on the rod 34. In use, the operator raises the weight, and consequently lowers the table, by depressing a pedal 48. A receptacle is then placed in position and the pedal released to allow the weight to raise the receptacle so that it embraces the shoot 16. The filling operation is then started by the action of a stud 67 on the rod 34 upon a bar 63 connected with the clutch-release mechanism of the feed members. When filling is complete, a projection 58 on the rod 34 engages a cam-surface 53 adjustably arranged on a link 49 and presses it to the left to allow the bar 63 to fall and stop the feed. The position of the cam 53 can be adjusted by rotating a hand-wheel 57, so that receptacle of different sizes can be dealt with.

Title: Improvements in or relating to the production of tufted carpets
Inventor: SANDIFORD DENIS JAMES HENRY
IPC: D05C17/02
Filed: 1965-01-14
Abstract: In a tufted carpet the tufts are pushed through a backing comprising a laminate which comprises a plurality of substantially uniaxially oriented films formed from crystallisable polymer and bonded together to provide strength in the laminate in two perpendicular directions. Examples of crystallisable polymer are polymers of propylene, high density polymers of ethylene, polymers of 4 methyl pentene-1, block copolymers of one or more of these polymers; polyesters, e.g. polyethylene terephthalate, polyamides, e.g. polyhexamethylene adipamide, polyhexamethylene sebacamide or polycaprolactam, and oxymethylene polymers and copolymers.  The polymers or copolymers may be mixed with stabilisers or antistatic agents.  The oriented films are preferably heat set before the backing is used, and are of the same or different polymers.  The angle between the direction of orientation of any two adjoining films is preferably 90 DEG  but where several films are used it may be a different factor of 180 DEG . The films may be bonded together by adhesive, e.g. an adhesive activated by radio frequency heating, or by solvent welding, ultrasonic bonding, or "flame-laminating" as descrbed in Specification 1,081,547.  In one preferred embodiment a polypropylene/polyethylene laminate is produced by double extrusion and drawn in one direction.  After heat setting the laminate is bonded to a similar laminate, but oriented in a second direction, by passing the pair of laminates, polyethylene faces in contact, between heated rollers.  To retain the tufts in the backing a thermoplastic latex is applied to the reverse side of the carpet after tufting and is dried and cured.  Alternatively a thermoplastic coating of lower melting point than any of the films of the laminate is applied to one side of the laminate during its manufacture, and after tufting is heated to melt it and seal the tufts in position.  The thermoplastic latices which may be used include rubber latices; copolymers of vinylidene chloride with one or more of acrylonitrile itaconic acid, or methacrylic acid; polyvinyl acetate; partially hydrolised polyvinyl acetate; copolymers of vinyl chloride and vinyl acetate; copolymers of butadiene with styrene and/or methyl methacrylate or with acrylonitrile; methyl methacrylate/methacrylic acid copolymers; copolyesters of terephthalic acid and another carboxylic acid with a glycol; copolymers of vinylidene chloride and vinyl chloride or alkyl acrylates, and copolymers of two of vinyl chloride, vinyl-acetate and ethylene.

Patent GB-122881-A (GB)
Title: Improvements in or relating to Barbed Wire.
Inventor: ROGERSON WILLIAM HENRY
IPC: B21F25/00
Filed: 1918-02-01
Abstract: 122,881. Rogerson, W. H., and Bedson, N. P. Feb. 1, 1918. Addition to 112,152. Wire.-The machine for forming barbed wire described in the parent Specification is improved or modified by arranging that the cutters for the barbs move in a path substantially parallel to the welding die heads and improvements are also effected in the feed rollers for the main and transverse wires, in the welding circuit connexions, and in the winding drum for the finished wire. As shown, the welding electrodes 8, 9 are mounted in plungers 4 reciprocated in guides 1 by means of bell-cranks 7 actuated from a cam-shaft 6, and the electrodes may move relatively to the plunger against the action of adjustable springs. Alternatively, the electrodes 8, 9 may be carried at the ends of rocking levers. Cutters 14 are attached to the dies or electrodes 8, and move with these, and co-operate with adjustable cutters 15 fixed to the wire guides 20, which are secured in position by wedge-shaped members 41 so that they can be adjusted to allow for wear. The feed rollers are formed with reduced ends over which the wire passes and is normally free except when engaged for feed by adjustable segmental parts 18. The transverse wires are fed against adjustable stops, so that barbs of varying length may be cut. The dies 8, 9, Fig. 6, are in the secondary circuit of a transformer, the current to the primary coil of which is controlled by a rotary switch 27, comprising two relatively adjustable insulated disks fitted with connected metallic segments which control the timing of the current. When the dies 8, 9 move together completing the welding of the barb, contacts 22, 23 complete the primary circuit to a relay 24 which breaks the current directly, or through a contactor 26. The winding-up drum for the finished wire is driven by means of a series of planet wheels engaging a driven sunwheel, and also in engagement with a freely mounted annular gear which is braked by a brake controlled by a cable 38, Fig. 1, connected to a spring-controlled arm 31 provided with a notched wheel 30 around which the wire passes. If the drum is winding too quickly, the arm 31 is moved forwards, and the tension on the brake is relieved thereby diminishing the speed of the coil.

Connecting wires 7 each comprise a shank 10, which is coated with a low melting-point solder, e.g. 60% lead, 40% tin, for connection to external circuitry, and a collar 9 and a knurled head portion 8 which are initially coated with a second higher melting- point solder, e.g. 90% lead, 10% tin, which is used to connect wires 7 to end layers 5. In a first embodiment, Fig. 1, the end layers 5 are applied first and the cerment layer 2 is then fired on. The value of the resistance is then adjusted by cutting a helical groove in the layer 2 and a layer of glaze 6 may then be provided. The wires 7 are then positioned and soldered on by mounting the resistor between two arms of a jig (15, Fig. 4, not shown) and heating the second solder with heat lamps (20), the shanks 10 being kept relatively cool to prevent melting of the first solder. A coating 23 of copolymerized epoxy resin and phenolic resin is then applied.  In a second embodiment, Fig. 7 (not shown), the cermet layer is applied before the end layers 5, which may contain no palladium. In addition to a copolymerized resin coating, this resistor has an outer epoxy jacket 31.

Abstract: 1,060,554. Scrap shredding apparatus. KAISER INDUSTRIES CORPORATION. Jan. 18, 1966 [Feb. 5, 1965], No. 2347/66. Head ing B2A. Mobile apparatus for shredding ferrous scrap e.g. junk cars, comprises a supporting structure 10 .. 13 in the form of a vehicle frame carrying a mill 20, and a prime mover 15, e.g. a diesel engine. A scrap gripping and feeding device 26, 27, 30 is associable with the mill inlet, and is driven by an hydraulic motor 28 the speed of which is variable in response to the speed of the mill. In operation, when overloading reduces the mill speed, this is sensed by a tachometer 50 which operates a controller 52 and thereby actuates a valve 53 to reduce the feed rate. Reduced scrap is discharged through a hopper 31 on to a belt 32 which carries the scrap upwards to a shoot 33 where it is magnetically separated by a drum 35. Ferrous material is conveyed to a screen conveyor 36, small scrap being delivered via a belt 39 to a truck 43 Fig. 2 (not shown). Oversize material is returned to the inlet hopper 19 of the mill. Non- ferrous material is delivered by a conveyor 37 to a divided box 45 wherein denser material is separated from the less dense.
