Title: A card controlled vending apparatus
IPC: G07F7/02
Filed: 1966-07-06
Abstract: 1,089,249. Vending apparatus. TATEISI ELECTRONICS CO. July 6, 1966 [July 10, 1965], No. 30368/66. Heading G4V. Vending apparatus adapted to be operated by cards of predetermined different monetary values is provided with a detector sensing the monetary value of an inserted card, a counter operable in response to the detector for producing an electrical signal corresponding to said monetary value, and means for dispensing articles or rendering services which are operable in response to said electrical signals. Each card has a base of vinyl chloride material and is printed with circular or striplike marks in magnetic ink. A plurality of cards may be separable from a single sheet along perforated lines. Alternatively the card is provided with a coded arrangement of marks or apertures according to its monetary value. The card 100 is inserted in a guide shoot 203 and conveyed by driven rollers 204, 205, 207 and 208 past a detector 209 such as a proximity switch. Two jaws 210, 214 are provided pivoted at 211 and spring-urged to the position shown. The jaws are individually movable by solenoids 217, 220. If the card fails to actuate the detector it drops between the jaws striking the surface 221a and is returned at 222. Actuation of the detector causes the solenoid 217 to operate. This closes the jaw 210 on to the jaw 214 to hold a card. After an article has been dispensed from the apparatus, the solenoid 220 is energized to pivot the jaw 214 counterclockwise and allow the card to fall into a receiver 216. As shown in Fig. 4, the apparatus is adapted to vend ten differently priced articles. The detector 209 responds to the inserted card(s) to pulse a counter 310 energizing a relay 341-350 corresponding to the value of the inserted card(s) and closing the appropriate contact 411-420. In addition, the flip-flop 471 is moved over to actuate a relay 475 closing contact 477 to energize solenoid 217. Depression of a selection switch 451-460 causes a solenoid 431-440 to actuate an article dispensing means and close contacts 472 and 478. Closure of contact 478 completes the circuit of solenoid 220. Closure of contact 472 resets the flip-flop 471 and counter 310. Operation of the switch 479 before a selection switch by a customer, resets the circuit and deenergizes the solenoid 217 whereby the card is returned at 222. If the monetary value of a card is determined by the length of a mark, the output of detector 209 is connected to one input terminal of an AND circuit and the output of a pulsing relay to the other input terminal. The output of the AND circuit is applied to the counter 310. A modification of the circuit is described wherein the apparatus may be operated by coins or cards, Fig. 5 (not shown).

Title: Improvements in or relating to hydraulic tappet mechanisms for internal combustion engines
IPC: F01L1/245
Filed: 1950-12-13
Abstract: 692,886. Tappets. GENERAL MOTORS CORPORATION. Dec. 13, 1950 [Jan. 5, 1950], No. 30406/50. Class 80 (iii). [Also in Group XXVII] A hydraulic tappet particularly for internal-combustion engine valve gear comprises a piston 28 and cylinder 14, a valve controlled passage 29 in one end of the piston for flow of liquid from the interior of the piston to the cylinder, and a vent 49 in the other end of the piston, cooperating with a channel 50 in a rod 6 actuated by the tappet, for the release of gases escaping from the liquid in the piston. The tappet is actuated by an offset cam 4 which causes the tappet to rotate, and the passage 29 is controlled by a ball valve 35 surrounded by a cage 31. The end 5 of the pushrod 6 seats in a concave recess in the top of the piston and is provided with the recess 50 and passages 51 which co-operate with the vent 49 to permit the escape of the gases. The piston 28 receives oil from the engine lubricating system through passage 18 and ports 19, 41.

Title: System for indicating the liquid level in a continuous-casting mould or the like
IPC: B22D11/18
Filed: 1963-07-31
Abstract: 1, 011, 205. Automatic level control. UNITED STATES STEEL CORPORATION. July 31, 1963 [Aug. 13, 1962], No. 30437/63. Heading G3R. [Also in Division G1] To measure the position of a horizontal plane at which a marked change of temperature occurs (e.g. the level of molten metal in a continuous casting mould, or else the level of a non-heated liquid on a heated rod placed vertically therein), a plurality of thermocouples T8 to T20 (Fig. 3) arranged vertically and each connected to respective points on slide wire resistors 20 or 22 (Fig. 3) which form part of a self-balancing bridge having motor driven contacts 58, 60. The e.m.f. of a battery, 54, is made equal to the sum of two thermocouple voltages one inside and one outside the high temperature region, and thus the contacts 58, 60 are driven to a position between two particular thermocouples, one T14 below the liquid level and one T13 above it. A contact 84 (Fig.4) on a second bridge 75, 80, presets a required liquid level, since the voltage Ee between it and a contact 74, operated from the motor 68, can control either the rate of flow of liquid supply, of the extraction rate of pinch wheels which withdraw the solidified metal. Operational departures from the thermocouple output curve may be compensated for by replacing the battery by two thermocouples, one in the high temperature region T19 and one outside it T8 (also Fig. 5 not shown). The measuring thermocouples may all be arranged in one resistance arm 20<SP>1</SP> (Figs. 7, 8, 10 not shown), the thermocouples then being formed by bonding metal wires to the mould itself; and the battery 54 then has an e.m.f. of half the previous value. Unequal thermocouple response is then compensated for by using the difference between the voltage of two thermocouples T8 T20 (Fig. 8 not shown) instead of a battery, and a potentiometer 124 allows adjustment of this effective reference voltage. Movement of the contacts registers, via a pointer 70, on a scale 72, and the motor drive may rotate a wiper 104 (Fig. 4) to progressively switch on more indicator lamps 102, and may also operate, via synchros 92, 94 or 112, 114, either a pointer 96 or a shutter 106 on a vertical strip lamp 108. A second pair of sliding contacts 58<SP>1</SP>, 60<SP>1</SP> (Fig. 6 not shown) responsive to the temperature change resulting from shrinkage upon solidification within the mould may provide an indication of the level at which this occurs, and this may be recorded, together with the level of liquid, on a dual pen recorder.

Abstract: 1330735 Presses for metallic powder MANNESMANN-MEER AG 1 July 1971 [3 July 1970] 30804/71 Headings B5A and B5F An hydraulic press for metallic powders comprises two pistons 2, 6 shaped to define annular spaces 3, 4 respectively, a punch 19 and die 17 connected to pistons 2, 6 respectively and a tapoff valve 7 connected to the die piston 6 via an arm 10 and to the punch piston 2 via mechanical setting devices so that movement of the die 17 depends upon that of the punch 19. The setting devices comprise a lever 8 which is pivoted on the arm 10 and carries a vertically adjustable spindle 16 having a roller engaging a lever 11 which is provided with a roller for engaging a straight edge 15 connected to the punch piston 2 via an arm. The die 17 is provided with a through bore closed at one end by a stop 18 fixed to the press frame 13. To carry out a pressing operation, pressure liquid is fed by a pump and motor M into the cylinder body above the piston 2 which consequently moves downwards as pressure liquid in the space 3 is exhausted through the valve 7 via valves I, II and a non-return valve (not shown). When the straight edge 15 contacts the lever 11, the lever 8 is depressed so that passage of liquid through the valve 7 is restricted or cut-off. This leads to liquid from the space 3 entering the space 4 and movement of the piston 6 and hence the die 17 . downwards. The lever 12 can be slid at right angles to the piston movement in guides 14 so that the velocity ratio of the pistons 2, 6 may be varied. By adjusting the spindle 16 the ratio of the displacement of the punch to that of the die may be varied. After pressing is completed the pistons 2, 6 are returned to their initial positions under the control of valves I, II, III.

Title: Improvements in catalytic reactions
IPC: B01J16/00
Filed: 1926-12-06
Abstract: 262,475. I. G. Farbenindustrie Akt.- Ges. Dec. 7, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Chlorine ; hydrogen.-The loss of cuprous chloride in the Deacon process may be overcome by passing the reaction gases containing the volatilized catalyst into contact with porous masses such as active carbon, active silica, and porous pumice arranged in the reaction vessel. The porous mass may be mixed with the catalyst, or may be separate therefrom. It is advantageous to place a porous mass on each side of the catalyst and to reverse the gas stream from time to time. The invention may be applied to the production of hydrogen and phosphoric acid by the interaction of water and phosphorus in the vaporous condition in the presence of a catalyst. If compounds containing the catalyst or the catalyst itself be placed adjacent the porous mass in the reaction chamber, the catalyst which becomes deposited within the pores of the porous mass is very active. Thus, by passing a mixture of phosphorus and water vapours through a layer of metallic copper and then through a layer of porous pumice stone, the latter after it has adsorbed the catalyst is more active than the catalyst obtained by impregnating pumice with a copper salt and igniting. The catalyst in a porous mass may be replenished, when necessary, by placing the metal, for example, upon or within the porous mass.

Abstract: 820,746. Optical-projection apparatus. KODAK Ltd. Oct. 10, 1956 [Oct. 10, 1955], No. 30866/56. Class 97(1) A slide projector includes a slidereceiving magazine having a portion aligned with the slide track through the gate and a member for positioning an ejected slide, carried by the gate and tending to occupy a position in which a yieldable part thereof extends into the magazine across the path of an ejector slide, said part being adapted to yield when engaged by a slide entering the magazine and, upon automatic return movement, to deflect the slide, when fully ejected, out of alignment with the slide track. In the form shown each slide 18 is fed downwards between a fixed apertured front plate 16 and an apertured pressure plate 50. The latter is mounted on a U-shaped spring 38 having vertical side members connected by a horizontal member 43. The pressure plate assembly is carried by a frame having vertical side members 31 connected by transverse members 27, 44. The transverse member 44 and projections 29 on the member 27 lccate projections- 55, 58 on the pressure plate. The vertical members of the U-shaped spring 38 are bent rearwardly in the centre where they have outwardly projecting lugs secured by rivets 40 to the rear of the frame members 41 to which are also secured, by screws 75, spring fingers 73 which are bent forwardly at 71 and connected by a transverse portion below the projection aperture. As each slide is pushed downwards from the gate by the succeeding slide it pushes the portions 71 downwardly and rearwardly until it is free of the gate when the spring fingers push it forward in the magazine 37. Each slide is thus brought to a position behind that which preceded it.

Abstract: 793,323. Grinding. PITTSBURGH PLATE GLASS CO. Oct. 28, 1955 [Nov. 1, 1954], No. 30885/55. Class 60. Apparatus for finishing the edge of a glass plate comprises means for rotating the plate so that its edge engages a rotating grinding wheel which yieldably contacts the edge of the plate, and auxiliary pressure means for increasing the pressure with which the grinding wheel engages the plate edge at selected portions of the edge for giving the edge at those portions a higher degree of polish. The invention is described as applied to a known type of machine in which two glass plates A, B are held in a chuck 15 and rotated by a motor 16 so that their edges are brought into contact with two driven grinding wheels 27, 37, each of which is carried at the end of a pivoted counterweighted arm (24, 30) and controlled by adjustable followers (21, 40) contacting patterns A<SP>1</SP>, B<SP>1</SP> rotating synchronously with the plates A, B. The pivoted arm 30 carrying the grinding wheel 37, which is intended for giving the plate edges a finer finish than that provided by the main grinding wheel 27, is urged towards the plate edges by a counterweight 47 connected to the arm 30 by a chain 45 passing over a sprocket wheel 46, and the auxiliary pressure for providing a satin finish to selected portions of the plate, e.g., the edges a is effected by fluid pressure supplied to a cylinder 50. The piston rod 52 of this cylinder carries a crosshead 61 which is connected by two springs 60 to the rear end of the cylinder and two springs 64 to the chains 45 ; the cylinder 50 is adjustably mounted in a trough 53 to permit variations in the tension of the two sets of springs and also in the size of the plates being finished. Fluid pressure is applied to the right-hand end of the cylinder 50 so as to apply the auxiliary pressure through a solenoid valve 73 controlled by a switch 80 actuated by a cam 20 arranged to be rotated synchronously with the plates A, B; the cam 20 consists of two discs which are formed with dwells to cause application of the increased pressure and are relatively adjustable to vary the length of the dwell. The apparatus may also be arranged to act on a further pair of plates, a second counterweighted chain 45 being shown in Fig. 2 as part of the arrangement for this purpose.
