Title: Anti-jackpotting device for coin or check operated vending machines
IPC: G07F9/02
Filed: 1947-12-12
Abstract: 645,499. Coin-freed apparatus. HARRIS, C. F. Dec. 12, 1947, No. 32817. Convention date, Dec. 12, 1946. [Class 27] In a coin-freed electrically-operated vending machine, a test circuit is closed towards the end of each operative cycle to ascertain whether starting contacts, which by then should have reopened, have opened, and to disable the machine and return coins if they have not. In Fig. 1, each operation of a delivery motor 22 is initiated by a relay 13 and contacts controlled by a cam 49 which, with a test cam 51, is driven by a motor 45. Momentary closure of the coin switch 11, through normally closed contacts 33 of a master latch relay 31, energizes the relay 13 which holds at contacts 17 and closes the circuit to the cam motor 45 at contacts 15. As the cam 49 turns and its lobe clears the follower, it reverses contacts 53, 55, the latter breaking the circuit of relay 13 and the former closing a holding circuit for the cam motor 45 and also a starting circuit for the delivery motor 22 which then runs to complete one delivery cycle under the control of conventional means (not shown). The motor 45 is stopped at the completion of one revolution of its cams and cam 49 re-opens contacts 53 but, just before this, the test cam 51 momentarily closes contacts 57. Should the normally open contacts 15 have remained closed, owing to the coin contacts 11 or they themselves sticking, this closure of contacts 57 energizes the master latch relay 31 to open contacts 33, a latch (not shown) holding them open. Contacts 33 are included in the circuits which initiate each operation of the machine; consequently further operation is prevented. Repeated operation for the one coin, resulting in the machine delivering its entire contents, cannot therefore occur. The fault must be cleared and the relay 31 manually reset to put the machine back into service. Returning coin. Whilst the machine is operating, a relay 19 is de-energised and projects a pin 25 into the coin chute 27 to return any further coins inserted. A switch 71 is opened when the machine becomes empty and also de-energizes relay 19 to return coins. Coin action, multiple-coin. Change delivering. The Specification also describes a modified arrangement (not shown) for operation alternatively by nickels, dimes and quarters. In the case of a dime, a nickel pay-out solenoid is energized to deliver one nickel whilst, for a quarter, contacts operable by a four lobed cam driven by the motor 45 are rendered effective and close the circuit of the pay-out solenoid four times to discharge four nickels in change.

Abstract: 910,976. Semi-conductor devices. TELEGRAPH CONDENSER CO. Ltd. (Sprague Electric Co.). Sept. 27, 1960, No. 33127/60. Class 37. A multiple semi-conductor assembly comprises a semi-conductor slice having a number of regions 27 of alternating P and N-conducting type, so as to provide at least one PN junction, semi-conducting components (e.g. alloy-junction or surface barrier transistors 22) being assembled on two or more of said regions and separated by one or more of said junctions, the separation between two junctions, or between a semi-conducting component and its nearest junction being at least 1.5 times the diffusion length of the minority carriers in the materials of the regions. The PN junctions function as insulators between the components. Some of the regions 27 may be provided with spaced ohmic contacts 23 so that they can be connected in circuit with components 22 as resistors. Capacitors of low capacitance may also be formed in the slice by providing ohmic contacts on opposite sides of a PN junction. If higher resistances or capacitances are required external components may be built on to the slice by using an insulating coating on which the components are deposited by printing or vaporizing for resistors, or multi-layer build-ups for capacitors. An alternative method of forming the multiple PN junctions is shown in Fig. 4. An N-type crystal is formed which is subjected to surface melting, and an impurity is introduced into the melted surface to pro. duce p-type conductivity. Grooves 48 are then cut from each side of the crystal, extending just beyond the PN junction to produce a plurality of junctions. The use of germanium, silicon, silicon carbide, and intermetallic compounds as semi-conductor materials, and of indium, gallium, antimony and arsenic as impurities is referred to. An insulating coating may be formed by evaporating quartz on to the slice.
