Title: Improvements in or relating to coin operated vending machines
Inventor: MAXWELL STEWART ALFRED
IPC: G07F5/12
Filed: 1961-06-02
Abstract: 937,428. Coin-freed vending apparatus. FISHER & LUDLOW Ltd. July 2, 1962 [July 2, 19611, No. 19900/61. Class 27. A coin-operated vending machine comprises means for setting up the machine in response to the insertion of the correct number of coins, the means consisting of a setting-up relay SU, Fig. 3, in an electrical circuit having a pair of normally-open relays 1L1, 1L2 for each coin over and above one, the or each pair of relays being adapted to be closed in sequence in response to the insertion of the or each coin other than the final coin. When a coin inserted in the machine has been accepted by the selector mechanism 11, Fig. 2, which tests the coin for thickness, diameter and magnetism, it passes through a shoot 21 and moves a trigger 19 to actuate a switch 18 to an alternative position and back again. In the alternative position, the relay 1L1 is connected by the switch SW, Fig. 3, and contacts 1L2/2 across lines A, B leading from a supply transformer. Energization of relay 1L1 closes contacts 1L1/1 and 1L1/2. The return of switch SW to its initial position after the coin has passed the trigger 19 causes relay 1L2 to be energized through switch SW and the now-closed contacts 1L1/2. Energization of relay 1L2 closes holding contact 1L2/1 and changes over contacts 1L2/2 so that upon acceptance of a second coin by the mechanism 11 and movement of trigger 19 actuating switch SW, the setting up relay SU is energized through switch SW and contacts 1L2/2 to close a holding contact SU/1 and a contact SU/2 connected to a wire C joined to the dispensing mechanism of the machine. The setting-up relay, or a relay 22 operated thereby, moves a member into the coin path of the selector mechanism to prevent further insertion of coins during a dispensing operation. At the completion of the dispensing operation, a camoperated switch CS sends a pulse to a line D leading to a counter and returns the relays SU, 1L1, 1L2 to their initial condition. If the machine is to operate for more than two coins, the pairs of relays for each coin are joined in series, the final coin operating the setting-up relay SU. The machine may have selector buttons enabling black or white coffee with or without sugar, or chocolate to be dispensed and has a rotatable unit 9 having four magazines 10 containing coffee, chocolate, sugar and powdered milk which are delivered into a mixing vessel 15 supplied with hot water from a boiler 12, a pump 13 maintaining the water at a constant pressure. The setting-up relay controls the unit 9, a cup-dispensing unit 14 and a hot-water control valve 17.

Abstract: 623,029. High-frequency power measurements. STANDARD TELEPHONES & CABLES, Ltd. July 6, 1946, No. 20242. Convention date, June 30, 1943. [Class 37] Means for measuring the power transmitted by an electromagnetic wave, comprises a pair of antennµ mounted relative to the wave-front so that E.M.F's of like phase are induced in each antannµ proportional to the electric intensity of the wave together with E.M.F's respectively of opposite phase proportional to the magnetic intensity of the wave.. The antennµ outputs are rectified in square law rectifiers, and connected in series opposition to a galvanometer which deflects in accordance with the power of the wave. As shown, Fig. 1, hook-shaped probes 3, 31 extend into a wave-guide 1 and are disposed with their portions 5 extending in. opposite directions at right-angles to the wave-front. The probe dimensions being small relative to onequarter of the wavelength, then for any mode of wave oscillation in the guide the probes may be inserted to a corresponding extent to develop voltages proportional, respectively to aE + bH and aE - bH, where E, H represent the electric and magnetic vectors in the wavefront and a, b are constants. The rectifiers (not shown) produce voltages proportional to the squares of these values and their differential, which is proportional to 4ab(EH) and hence to the main power transmitted is applied to a galvanometer (not shown). A similar arrangement, Fig. 2 (not shown), is described for measuring the power of a wave radiated from an electromagnetic horn.

Abstract: 841,449. Circuits employing bi-stable magnetic elements. PHILIPS' ELECTRICAL INDUSTRIES Ltd. June 27, 1958 [June 28, 1957], No. 20703/58. Class 40 (9). [Also in Groups XXXVIII and XL (c)] In a permanent code store comprising bistable magnetic cores arranged in c matrices each comprising b rows of m cores, m-bit code groups are stored in each row by means of wires A 1  . . . Aa which are each threaded through predetermined cores in all the rows of all the fields, and a particular code group is selected by selecting one of these wires together with one of row-selecting wires B 1  . . . B b  and of matrix-selecting wires C 1  . . . C c , the code group being read out in parallel on wires S 1  . . . S m . In the arrangement described and illustrated in Fig. 4, a=16, b=12, c=90 and w=7. Fig. 1 shows the matrix corresponding to wire C 5 , only one wire A 9  of wires A 1 -A 16  being shown. Suppose, e.g., that the code group (9, 10, 5), i.e. the code group corresponding to wire A 9  in the 10th row of the 5th matrix, is required. The cores are initially set to " 0 " by passing a pulse through, e.g., all the wires B 1 - B 12  or a special restoring wire (not shown) threaded through all the cores. Half-write pulses are passed through wires A 9 , B 10 , thus setting up the 9th code group in the 10th row of each matrix, and a resetting pulse is then passed through wire C 5 . Those cores in the 10th row which were previously set to " 1 " will thus supply pulses to read-out wires S 1 -S 7  so that the code group is read out in parallel to gates and amplifiers (not shown). The wires A 1 -A 16  may be selected by opening one gate in each of the sets P 1 -P 4  and Q 1 -Q 4 , Fig. 2; the wires B 1 -B 12  and C 1 -C 90  may be similarly selected. The gates may each comprise a transistor rendered conductive by a negative control potential applied to the base, or a ferrite ring and transistor circuit (see Group XL (c)). The code store may be used, e.g. in an automatic telecommunication exchange, electronic computer or railway signalling system.

Class 40(6), [Also in Groups XL(a) and XL(b)] A tuning arrangement for a Klystron tube comprises a semi-conductor diode which is coupled to the cavity resonator so as to include, in the circuit of the resonator, a capacitance which can be varied by varying a reverse bias voltage applied to the diode. In the construction shown in Fig. 2 a reflex Klystron 1 has an internal resonator 3 closely coupled to an external resonator 7, which can be a length of waveguide, through a vacuum-tight window 8. A germanium or other semi-conductor diode 9 is connected to one side of the resonator 7 and has a lead 10 which is brought out from the other side to a variable source of reverse bias voltage 11. The bias lead is arranged to constitute a choke connector designed to prevent leakage of R.F. power down the lead. Output to a load is taken from the resonator 7 through an iris or aperture 12. In a modified construction for very high frequency operation the diode is offset to one side of the centre line of the external resonator to a position where the R.F. field is lower than at the centre line. In consequence the voltage across the diode is reduced as though it were connected through a step-down transformer, the reduction ratio depending on the amount of off-set. In the construction shown in Fig. 6 the reflex Klystron 1 has two output paths, one through the window 8<SP>1</SP> and output guide 13 to a load and the other through a window 8 to an external resonator 7 formed by a length of waveguide having a short-circuiting plate 14. The diode 9, fed with variable reverse bias voltage from the source 11 through a choke lead 10, is in the resonator 7. The nearer the diode 9 is to the plate 14 the less is the voltage across it. The nearer the diode (and its point of connection to the resonator) is to the plate 14 the larger is the step-down ratio of the equivalent transformer; the nearer the diode is to the position of maximum R.F. field the nearer the ratio of the equivalent transformer is to unity.
