Title: Improvements in coin freed vending machines
IPC: G07F11/54
Filed: 1932-07-04
Abstract: 400,357. Coin-freed article-delivery apparatus. BENKO, 1., 2, Hermanngasse, Vienna. July 4, 1932, No. 18878. Convention date, Aug. 19, 1931. [Class 27.] Articles stored in rotary drum.-Table coinfreed vending apparatus having a goods container rotatable about a vertical axis is characterized in that the coin-operated release mechanism is located above the goods container and is removable as an integral unit. The apparatus comprises a drum 3 with sector-shaped compartments, which is adapted to rotate between a hollow base 1 and a glass cover D having an opening through which the goods may be extracted. The drum is mounted on a hollow spindle projecting into the hollow base 1 and carrying a ratchet wheel 5, Fig. 4, limited to rotation in the direction of the arrow by a spring-pressed pawl 13. The wheel 5 is rotated by a spring-pressed pawl 8 on an arm 7 carried by a spindle 6 passing through the hollow spindle carrying the drum, and normally held against a stop 11 by a spring 10. When the shaft 6 is rotated, a catch 26 on the arm 7 engages a cam-projection 15 on a pivoted arm 14 and disengages the end 14a thereof from one of a series of pins s on the wheel ; the pawl 8 has now engaged a tooth of the wheel, which is thus revolved by continued movement of the arm 7, bringing the next compartment under the opening in the cover. Meanwhile the catch 26 has passed round the projection 15, and the end 14a of the arm 14 has been pulled by the spring 16 into the path of the next pin s to limit the motion of the wheel. On the return movement of the arm 7, the catch 26 rides over the projection 15. Coin action, mechanical-connection.-The coin M, Fig. 8, is inserted through a circular aperture in the cover into an aperture 17 in a disc 18 mounted beneath the cover and capable of being revolved by a handle 19, Fig. 1. The coin engages a spring-pressed pawl 21 and holds it clear of an abutment 20 on the disc which it would otherwise engage, thus permitting the disc to be turned to its full extent against the action of a spiral spring, and allowing the coin to fall through an aperture into the central part of the drum, which constitutes a coin container. The spindle on which the disc 18 is mounted carries a projection 24 which engages a projection 6a on the spindle 6. Fig. 1, thus rotating the drum.

Title: Improvements in the Decimal Read-Out for Fluidic Counters
Inventor: RENDER ALWYN BARRIE
IPC: F15C1/00
Filed: 1967-04-25
Abstract: 1,164,883. Fluid radix converters. RESEARCH ASSOCIATION FOR THE PAPER & BOARD PRINTING & PACKAGING INDUSTRIES. 16 April, 1968 [25 April, 1967], No. 18925/67. Heading G4P. [Also in Division G2] A fluid-mechanical apparatus for conversion of fluid signals representing a number in one number system to the corresponding digit in another system comprises a block 1 with a plurality of cavities 2 of appropriate size and shape to accommodate a corresponding number of movable members or pistons 3, and a flexible strip 7. Fluid digital signals representing a number in (say) binary are injected via inputs 4 to cause the pistons to move a predetermined amount within the cavities to displace the strip by an amount corresponding to the input number. The strip is graduated so that as it moves, marks representing the number in (say) the decimal system are brought into alignment with an optical system arranged to display the corresponding decimal digit on a screen. A spring 6 restores the strip to the " zero " position when there is no input. The number of cavities correspond to the number of places needed in the lower-based system to represent the maximum digit in the higher-based system and their sizes correspond to successive powers of the lower radix. To obviate the necessity of inconveniently large cavities, a ball-valve arrangement is described (Fig. 2, not shown) whereby two cavities of identical size can be used to represent, for example in the binary system, an " 8 " or a " 4 " according as the left or right inlet respectively is activated. Means are described (Figs. 10, 11, not shown) whereby substantially friction-free passage of the strip over the piston head is achieved. In a further embodiment (Figs. 7, 8, 9, not shown), a ball valve 23, activated by fluid input via a channel 35, controls the passage of a high-pressure stream input via a channel 28, that activates the pistons of the above apparatus. The action is that of an amplifying switch and the amplified fluid signals are converted as above to give, for example, a decimal read-out. In another arrangement (Fig. 4, not shown), a sampling valve 13, controlled by the fluid input, supplies fluid streams alternately to two control ports of bi-stable devices 14, each one of which has one outlet port connected to an inlet port (4, Fig. 1), of the converter. As a result, an output number signal appears for radix conversion then falls to zero so that the converter is reset for the next number to be input.

Title: Improvements in or relating to electric motor control systems
IPC: B60L15/04
Filed: 1929-06-21
Abstract: 334,973. Hall, A. J., Ramsden, H. K., and Associated Electrical Industries, Ltd. June 21, 1929. Master control.-In a sequential contactor master control system, an interlock on the last contactor to close to give the full parallel position is used to initiate the field weakening stages. The sequence of operations can be briefly described with reference to the motor circuit diagram, Fig. 1. Setting of the reverser and movement of the master controller to the first notch causes movement, if necessary, of the reversing switches FR, and thereafter closure of " fullfield " contactors F1, F2 and line switch LS1, after which contactor JR closes giving the first series position. Movement to the next notch causes sequential closure, under control of a current limit relay L of line switch LS2. and contactors RR1, R1 RR2, R2, RR3 and joining switch J, thereby accelerating to full series position. It is to be noted that in this sequence the contactor R3 is not closed, as the corresponding resistance section is shorted upon closure of switch J. The closing of switch J causes opening of contactors JR, RR1, R1, RR2, R2, and RR3. The next notch gives a transition to the first parallel position by closing contactors G and 10, an interlock on contactor G thereupon causing the joining switch J. to open. Movement to the next notch causes sequential closure in pairs under control of the current limit relay L, of the contactors RR1, R1; RR2, R2; and RR3, R3, thereby accelerating to full parallel position. Movement to the last notch causes an auxiliary relay to close over interlocks on the contactor R3. This relay causes the contactors RR3, R3 to open, and the " weak-field " contactors F3, F4 to close, interlocks on which cause the " full-field " contactors F1, F2 to open. Thereafter, under the control of the current limit relay L the contactors RR3, R3 again close to give the highest speed connection. A notching-switch and relay is provided so that automatic acceleration can be superseded by hand-controlled acceleration if necessary. A diagram of the control circuits is given in Fig. 2 (not shown), and a sequence chart in Fig. 3 (not shown). Specification 323,194 is referred to.
Patent GB-401236-A (GB)
Title: Auxiliary apparatus for the vending or dispensing of wares
IPC: A47F1/04
Filed: 1933-07-06
Abstract: 401,236. Controlling sales. GRUNBERG, G., 701, Nuslemi, Prague. July 6, 1933, No. 19182. Convention date, July 6, 1932. [Class 116.] In an auxiliary apparatus for use in the vending of wares according to the fortuitous presentation into view of a series of balls indicating the wares and including a bonus ball, the balls are piled in a track 3, Fig. 1, and are fed in succession to a rocker 8b, 8c, Fig. 3, or similar ratchet mechanism which, when moved by hand, allows the ball b last issuing from the track to drop into an inspection box 5 and the previously liberated ball b<1> to drop, at the same time, out of the inspection box and back into the track. The whole of the mechanism is mounted on a single plate 2 which may constitute the front of a box and is provided with a window 19 through which the ball in the inspection box may be viewed. The balls leaving the inspection box pass a window 61 on their way to a vertical passage 4 where they accumulate until they are raised to the track 3 by means of a handle 7a, a retaining spring being arranged in the passage to prevent the return of the balls when the handle is lowered. As the accumulated balls are reversed in order, the serial order of the stream of balls is continually changed. The rocker 8b, 8c is actuated by a spring-controlled pusher 13 and at each forward actuation liberates the lower ball and pushes the upper ball under a spring 12 to a hole 9 obstructed by the edge of a plate 8 on the rocker. The return of the plunger restores the plate to the position shown thus allowing the upper ball to fall into the inspection box where it is retained, and permitting a ball from the track 3 to roll into position in front of the arm 8. Each actuation of the pusher operates a counter 18 viewed through an opening 18a.

Title: Improvements in or relating to absorption refrigerating apparatus
IPC: F25B15/10
Filed: 1959-06-05
Abstract: 919,212. Refrigerating. ELECTROLUX Ltd. June 5, 1959 [June 11, 1958], No. 19278/59. Class 29. In a continuous cycle absorption system of the inert gas type having a tubular absorber 19 and an absorber vessel 10, the conduit 31 supplying mixed vapour from the evaporator to the absorber system is so connected to the latter that the vapours traverse none or only a minor part of the absorber vessel 10 before entering the absorber 19 and yet any liquid refrigerant flowing through pipe 31 at high ambient temperatures enters the absorber vessel to form therein a surface layer of high concentration. This forms in the vapour space of vessel 10 a high refrigerant concentration in equilibrium with the liquid layer and inert gas is displaced into the gas circulation, thus raising the total pressure in the system. Under still more severe operating conditions, refrigerant vapour not condensed in the condenser 25 flows through pipe 34 to the absorber vessel to form a cloud of refrigerant vapour therein which displaces inert gas into the gas circulation and increases the concentration of the surface layer of liquid in vessel 10. Liquid from absorber 19 passes into strong solution pipe 11 through a funnel 42 to prevent it disturbing the surface layer of liquid in vessel 10.
