Title: Change dispensing machine
IPC: G07D1/04
Filed: 1973-08-14
Abstract: 1484858 Change dispensing machine NATIONAL REJECTORS (UK) Ltd 14 Aug 1974 [14 Aug 1973] 39504/73 Headings G4X and G4V A change dispensing machine has an electrically driven hopper dispenser, perforated dispenser disc 11, for dispensing coins serially from a hopper 12, a counter 16 for counting coins as they are dispensed and for terminating a dispensing operation when a predetermined number of coins have been dispensed, an accumulator 6 into which coins are dispensed from the dispenser in each dispensing operation and held, a coin or rate validator 1 for validating inserted coins or notes to be changed, and means, solenoid 4 and flap 5, for releasing coins stored in the accumulator on detection of a valid coin or note. Coins dispensed from hopper 12 activate a micro switch 14 which controls a motor 15 which drives ratchet counting device 16. When the predetermined number of coins have been counted contacts 17 are closed to shut off motor 10. A valid coin is directed into coin box 2 and activates switch 3 which in turn operates flap 5. Return movement of the flap is sensed by switch 9 which starts motor 10, for a dispensing operation. Invalid coins are diverted along shoot 8 to receiver 7. If power to the machine is cut off a manually resettable cut-out relay 18 activates a reject rod 19 so that it is inserted in validator 1 to deflect inserted coins to receiver 7. The cut-out relay 18 is also operated by a timing circuit 20. If the motor 10 runs for more than a preset time the timer issues an output signal to relay 18. The machine can be adapted for accepting coins of different denomination. This is achieved by having several stages to an accumulator. Coins are dispensed into the first stage and a logic circuit controls the feeding from one stage to another. Insertion of a valid coin will cause emptying of one or a combination of stages depending on the value of the coin or note inserted.

Abstract: 842,834. Mechanical switches, without quickaction; electromagnetic switches. STANDARD TELEPHONES & CABLES Ltd. Dec. 9, 1958, No. 39604/58. Class 38 (5). Fixed coaxial connectors 1 are radially disposed in grooves between two annular rings 3 and 4 and an L-shaped coaxial connector 2 can be aligned with any selected connector 1 by virtue of shaft 10 and a rotatable joint 9. After alignment a sleeve member 11 which carries an inner sleeve 12 (see Fig. 2), is slidable to interconnect the inner and outer conductors of the connectors 2 and 1. The ends of the outer conductors of the connectors 2 and 1 and the ends of sleeve 12 have inclined edges to improve matching. The spacers 13, 14 and 15, 16 may be of irradiated polyethylene. The rotatable joint 9 is similar in construction to the sleeve member 11. In the embodiment of Fig. 3, only four fixed coaxial connectors 25 ... 28 are provided and the L-shaped connector 20, 21 with rotatable joint 23 carries two electromagnets 29, 30 which serve to withdraw sleeve member 24 prior to selection of a different fixed connector. When electromagnets 29, 30 are de-energized a spring 35 urges member 24 to engage coaxially with the selected fixed connector. The sleeve 11 in Fig. 1 could be electromagnetically operated but in this case slip-rings would be necessary owing to the possibility of successive rotations of member 2. The sleeve members 11 and 24 might slide inside instead of outside the outer conductors 2 and 21 respectively.

Title: Photographic film unit
IPC: G03B17/52
Filed: 1972-09-07
Abstract: 1406248 Self-processing film units EASTMAN KODAK CO 7 Sept 1972 [7 Sept 1971] 41566/72 Heading G2X A self-processing film unit has means for providing a path or guide for a severing device to separate the image-recording portion from a reservoir of processing liquid. The film unit shown is of the type having a photo-sensitive imagereceiving sheet 11 and a cover or process sheet 13, the two sheets being permanently coupled together along the lateral marginal portions 15. The unit is coupled at one end to a rupturable container 23 containing a supply of processing fluid by means of sheets 33, 34, which are attached by adhesives 35, 36 to the container 23 and by adhesives 20a, 20b to sheets 11 and 13 respectively. Thus sheets 33, 34 also act as a funnel to guide the processing fluid from the container, when ruptured by a pair of rollers (30, 31), Fig.2 (not shown), between sheets 11 and 13. Similarly the unit is coupled at its other end to a trap portion 8 for receiving any excess processing fluid, with a similar funnel arrangement, also attached by adhesives to sheets 11, 13. Both the supply end and the trap end of the unit have an outer cover 27, 37 of relatively stiff cardboard. At the supply end, the edges 39, 41 of respective sheets 11, 13 and the opposed edges 43, 45 of cover 27 define an elongate slot 40 which can receive and guide a severing device for cutting the whole of the supply end away from sheets 11, 13. The inner surfaces of sheets 33 and 34 have adhesive coatings 67a and 67b which are activated by the passage of the processing fluid thereover, so that they are automatically sealed together after passage between the rollers. Thus after the supply end has been cut away, the portions on both sides of the cut remain sealed, and no leakage of fluid can take place. A similar sealing is effected at the trap end. Instead of cutting away the two ends, they may be, if preferred, simply folded over against the back of the final print.

Abstract: 1,200,787. Wrapping articles. SCHWEIZERISCHE INDUSTRIE-GES. 13 Sept., 1967 [14 Sept., 1966], No. 41697/67. Heading B8C. A tube of substantially rectangular crosssection and comprising a single sheet of packaging material folded around an article is closed by a longitudinal seam and two transverse seams and has its two opposing narrow longtudinal sides bent inwardly. The corners of the tube are strengthened by further marginal folds. Near the centre line of one of the faces 3 of the tube in the preferred arrangement, the opposed edges 4 of the sheet 1 are folded outwardly, welded together and later folded back against the face 3. The edges 5 at the ends of the tube are similarly welded together to form fin-seals, and the narrow sides 2 are bent inwardly to form creases 16. In the manufacture, a length of packaging material such as plastics-covered aluminium foil is folded about successive articles to produce a filled tube of substantially rectangular cross-section, Fig. 5. The tube 10 is then advanced in the direction 13 about two guide plates 12, the distance between which decreases in the forward direction to allow for the inward folding of the sides 2. Beyond the plates 12, the tube 10 moves between two stationary jaws 14 having edges 15 which produce the fold lines 16. The edges 17 of the tube pass between the appropriate upper or lower surface of jaws 14 and pressure rollers 18 to form margins 19. The elements 14, 18 may be heated to cause welding of the margins 19. The tube is advanced by driven heated rollers (not shown), which grip and simultaneously seal the margins 4, and the resulting seam is then folded flat against the tube. The subsequent transverse sealing and severing of the tube between articles is not described. In modifications, the seam 4 may be situated at a corner 17 of the tube and may be adhesively sealed without heat. Also, the sides 2 of the tube may be merely concave instead of having sharp folds 16.

Title: Hydraulic brake booster
IPC: B60T13/14
Filed: 1971-09-08
Abstract: 1322156 Hydraulic boosters BENDIX CORP 8 Sept 1971 [21 Sept 1970] 41789/71 Heading F2F In an hydraulic brake booster, operatoractuated means control a valve which communicates pressure fluid to a chamber between one end of a piston and a housing to drive the piston; a chamber between the housing and the other piston end contains a plastically and/or resiliently deformable element which senses the piston movement that pressurizes the element operating force transmitting means opposing the piston movement. A ball valve 50 is lifted from a seat 46 by the operator actuator means 88 through ports 90, 98, 96, 102 to allow pressure fluid to flow to the chamber 18 from an inlet 28, through passages 54, chamber 36, passage 104, chamber 34, and passage 56, thus moving the piston 16. Piston movement operates a rod 66 coupled to a brake master cylinder. A reaction from the rod 66 deforms a resilient washer 62, seated on a dish-shaped annulus 70, and forces back a disc 74, in turn actuating the actuator 88 through longitudinal pins 82, a reaction washer 84, a sleeve 92 and the port 90. Pressure fluid is also supplied to a chamber 38 through passages 60, 58 and this reacts on a plunger 48 and the ball 50. Fluid pressure in the chamber 34 also reacts on a lateral part of the member 102. As the piston 16 has to move a predetermined amount before deformation of the washer 62 reacts on the actuator 88, the two hydraulic reactions are the only reactions transmitted to the actuator. When the boost pressure, resulting from brake force, in chamber 18 attains a predetermined amount, the fluid pressure in the chamber 38 forces the ball 50, the member 102, 96 rightwardly against a spring 100, thereby seating the ball 50 on the seat 46 to cut-off pressure fluid supply to the chamber 18. In the absence of pressure fluid, e.g. due to a malfunction, the booster is actuated manually from the actuator 88, through the port 90 and a sleeve 80, to the piston 16.
