Title: An Apparatus for Changing the Information Recorded on Cards.
Inventor: AKAMATSU HIROO
IPC: G07F7/02
Filed: 1967-05-22
Abstract: 1,175,300. Statistical apparatus; vending machines. TATEISI ELECTRONICS CO. 22 May, 1967, No. 23589/67. Headings G4M and G4V. In a vending machine the amount of credit remaining on a credit card is read and stored, an amount corresponding to a selected article is subtracted from the stored amount if the amount of credit remaining is sufficient, and the new remaining credit is recorded on the card after erasing the original amount. A credit card 1 placed on a drawer is inserted in a vending machine and when a ferrite mark 2 on the card is sensed by detector 5, a bi-stable circuit 7 is set to energize a solenoid 9 which locks the card against withdrawal and causes the card to be pressed against magnetic heads 17- 19. A contact 9s closes to set bi-stable circuit 11 and energize a motor 12, which through a rack and pinion, drives heads 17-19 relative to two tracks of magnetic marks 23, 24. Clock marks 23 are sensed by head 18 and advance a counter 26-28, the outputs of which are applied to a diode matrix 39 serving to distribute the data bits from track 24 (sensed by head 17) to respective stages of a counter 48-51, these bits representing the amount of credit remaining on the card. The outputs of counter 48-51 energize one or more of relays 67-70 via diode matrix 60, the relays 67-70 being energized if the amount of credit remaining is greater than 10, 20, 30 or 40 cents, for example, and a visible indication of the credit remaining is given by lamps 71-74. When one of articleselection buttons 56-59 is pressed, the corresponding relay 75-78 and article dispensing solenoid 79-82 are energized, provided that the credit remaining is sufficient for the article selected. Energization of any one of relays 75-78 triggers a pulse generator 86 feeding pulses to counters 48-51 and a further counter 87. At the end of the read scan a switch 22s, Fig. 5, was closed, so that counter 48-51 is counted down by the pulses from generator 86 until counter 87 energizes the output corresponding to the energized relay 75-78, thus effecting subtraction of the appropriate sum for the article selected. At the end of the subtraction operation, motor 12, Fig. 5, is reversed and relay 36 is energized to energize erase head 19 and connect head 17 to the output of AND gate 109. As the heads again traverse the card, clock pulses 23 step counter 26-28 backwards and the stages of counter 48-51 are read out in the reverse order by matrix 39 so as to record the new remaining balance on the card by means of head 17. At the end of the recording scan, switch 21s, Fig. 5, is closed to reset the apparatus to its initial condition and allow the card to drop out under gravity.

Filed: 1975-06-03
Abstract: 1509765 Treatment of fibrous sheet materials EPEX 3 June 1975 [4 June 1974] 23931/75 Headings D1L and DIP [Also in Division B8] Fibrous materials, e.g. corrugated cardboard, in sheet form, are treated by an impregnation process in which, prior to impregnation, the moisture content of the fibrous material is adjusted either by moistening using steam or atomised cold water or by drying using hot or cold air, and following impregnation with treatment products for improving the moisture impermeability of the material, the sheet is conditioned by treatment while draining off excess treatment product with hot air and then with a stream of cold air. Impregnation is preferably effected by dipping the cardboard sheet e.g. contained in a basket in a bath of an impermeablising agent such as a petroleum product, paraffin and wax, a polyolefin or a mixture of paraffins and an emulsion of polyvinyl ester alcohol. Following impregnation the sheets may be further treated with a non - skid agent such as colloidal silica. An installation for carrying out the process comprises a series of stations through which the sheets are conveyed in a basket 21 suspended from a pulley block 22 movable along a continuous rail 23 e.g. by a linear motor, including an atomising wetting device 13, a steam wetting device 12, a spraying device 11 for special effect products a preconditioning tunnel 7 provided with an air curtain 8 and containing a hot air circulating blower 10 and a cold air blower 9, an isothermal enclosure 4 containing an impregnant vat 1 into which, the basket is lowered to impregnate the fibrous sheets, and after a dwell time of a few seconds is withdrawn to allow the sheets to drip during which time hot air is blown from a blower (5) Fig. 3 (not shown) communicating with the enclosure 4. A cold air blowing station 14, 15, 16 follows the enclosure 4, for post conditioning the treated sheets. In an alternative embodiment Figs. 4-6 (not shown) a post conditioning tunnel is provided downstream of the enclosure 4 and containing a hot air blower, a cold air blower and a final cold water spray there being a gully at the bottom of the tunnel for collecting drips from the sheets which are passed immediately into the tunnel after removal from the impregnation vat. In both embodiments, the basket in which the sheets are carried preferably contains a pivoted frame so that the sheets can be inverted during the dripping or draining phase to prevent agglomeration of impregnant at the bottom thereof. The sheets may be impregnated with waterproofing or fireproofing products.

Abstract: 919,344. Brakes. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. July 24, 1959 [July 25, 1958], No. 23967/58. Class 103 (1) [Also in Groups XXIX and XXXVIII] A remote control comprises several displaceable -members e.g. pistons or solenoids  selectively displaceable singly or in combination on actuation of an input member, the said displaceable members imparting movement to an output member. In the first embodiment, Figs.1 and 2, there are three displaceable members formed by jacks A, B and C. The jacks A, B and C are operated in the desired sequence by an input -member movable in step-by-step manner to act directly or indirectly on the jack control -valves. The jacks A and B act on a lever L connected by a link R to the shaft S of cams X, Y which are-rotated through an arc in four steps first clockwise then counter clockwise. The operation of the jack C causes a roller Z carried by an output member OM to move from the cam X to the cam Y. The arrangement is such that for each successive step of the input - member-only one of the valves controlling the jacks A, B, C changes its state. A stop N limits movement of the lever when both jacks A and B are operated so that the output member OM is moved progressively in steps through its range to actuate, e.g. an engine throttle, fluid pressure operated brakes or a self-lapping valve controlling the admission of fluid to a brake cylinder. In another example the three jacks act on two floating levers connected to the output member OM. The input member actuates switches which control an intermediate switching circuit which controls the solenoidoperated control valves of the jacks. For each successive step of the input member only one  the switches actuated thereby changes its state
