Title: Improvements in and relating to coin freed liquid measuring and dispensing machines
IPC: G07F13/02
Filed: 1946-11-01
Abstract: 647,822. Coin-freed apparatus for dispensing petrol. ROWE, A .G. Nov. 1, 1946, No. 32463. [Class 27] Change-giving apparatus. - Apparatus for dispensing petrol is provided with mechanism for delivering change coins comprising a series of rotary drums 49-54 with peripheral pockets 55 each containing change coins of appropriate value, the drums being rotated step-wise to empty their pockets in turn and each in turn becoming coupled to the preceding drum when the latter has completed a revolution and emptied its pockets. In the mechanism shown, the drums rotate in a stationary casing 63 with a coin discharge slot opposite each of the drums. The coin-insertion slide of the dispensing apparatus reciprocates an arm 47 which drives a pinion 58 to impart step-wise movement to the first drum 49, the remaining drums 50-54 being each initially locked by a bolt 73 held in a slot 72 in the casing by a boss 61 on the preceding drum. When the first drum 49 has completed a revolution and discharged all its coins, a recess in its boss 61 comes up to the bolt 73 which is thereupon retracted by a spring 71. This frees the next drum 50 from locking engagement with the casing and connects it to the first drum 49 so that change coins are now delivered from the second drum. The succeeding drums 51-54 similarly come into action as the preceding ones are emptied. Coin action, thrust and multiple-coin.- Full inward movement of the coin insertion slide 17 is normally prevented by the engagement of the ends 23 of levers 22 with steps 27 in the edges of the slide. Coins 18, 19 inserted into a pair of apertures in the slide rock levers 21 connected with the levers 22 to free the slide for a full and effective inward movement. Delivery of liquids.-Inward movement of the slide steps forward a pin-wheel to close a switch controlling the motor driving a delivery pump. The pin-wheel is returned by a spring under the control of an escapement actuated by a meter in the delivery outlet, opening the pump motor switch when the quantity paid for and registered by the pin-wheel has been delivered. Apparatus with a manually-operated pump is also described.

Abstract: 1497753 Shift register stack BURROUGHS CORP 8 Aug 1975 [9 Sept 1974] 33103/75 Heading G4A A stack of shift registers R11-RM2 is arranged to selectively provide first-in-first-out and last-in-first-out stack operations. Each pair of registers, e.g. R21, R22, stores one word, the output of the second register R22 of the pair being connectible to the first register R11 of the register pair above it by a switch 13 and to the first register R31 of the register pair below it by a switch 15, each switch 13, 15 incorporating refreshing circuitry as do circuits 11 connecting the registers of each pair.  The stack stores one word less than the number of register pairs and may be in one of two states, state B in which the first register pair R11, R12 is empty, and state A in which the last register pair RM1, RM2 is empty. Refreshing is carried out by shifting each stored word down one register pair, by closing gates 15, and subsequently shifting each stored word up one register pair, by closing gates 13. Data is written into the stack via circuit 19 into registers R11 if the stack is in state A or register R21 if the stack is in stage B. Read-out for last-in-first-out operation is via circuit 21 from registers R12 or R22 for stack states A or B respectively. Read-out for first-in-first-out operation is via circuit 25 from registers R(M-1)2 or RM2 for stack states A or B respectively. The input to register R21 of the second pair may be modified so that instead of having separate units from the respective gate 15 and AND gate 39 of circuit 19 register R21 receives an input from an OR gate (115, Fig. 4A, not shown) receiving inputs from AND gate 39 and a further AND gate (113) receiving the output of register R12 and a control signal provided by control circuit 27 when the stack is in state A.
