Abstract: 935,870. Dispensing petrol. SYMINGTON WAYNE CORPORATION. Oct. 18, 1961 [Oct. 26, 1960], No. 37343/61. Class 116. [Also in Group XIX] A fluid (e.g. petrol) inventory system for controlling a plurality of dispensing units to enable a station operator to make available controlled quantities of fluid at the dispensing units, comprises fluid counter means which automatically prevents further dispensing when a particular quantity of fluid has been used, and a coded programme device connected through a comparator to code input means which is adjustable in accordance with a received message, the comparator producing an output signal in response to matching of proper code combinations, which signal adjusts the fluid counter to allow release of a further fluid quantity. Control of the supply of petrol through dispensers 16 from a storage tank 12 includes a counter assembly 30 (see Group XIX) which is actuated through additive and subtractive sections 32 and 34 respectively. A coded programme signal generator 44 comprises a coded programme device 50 including a coded card or sheet, inaccessible to the station operator, and code input means 52, the two being interconnected by a comparator 46. To release an additional supply of petrol the operator depresses push-buttons 54 on the unit 52 in accordance with a code obtained, for example, by phone from the suppliers. This code is compared with that set up in the device 50 and, if correct, a precision shaft rotation generator 72 is actuated to enter additively the amount to be released into the counter 30; the additional quantity is then available. Each gallon of petrol delivered from dispensers 16 generates a pulse in a device 36 which, via a solenoidratchet device 64, operates an associated counter 65 and a total counter 67. A subtractive entry to counter 30 is made through a shaft 90, and when this counter is brought back to zero, detecting switches S-27 ... S-30 complete the circuit of a detector 60 which disables the dispensers 16 to prevent further delivery until the next code, obtained from the suppliers, is used to reset the counter. Means for jamming the release means in response to improper tampering with the code push-buttons, may be incorporated.

Filed: 1970-09-15
Abstract: 1335983 Automatic control of temperature RAYPAK Inc 15 Sept 1970 [10 Nov 1969] 37652/70 Heading G3R In an automatic temperature control system (e.g. for a building) a plurality of gas-fired boilers B<SP>1</SP>-B<SP>4</SP> (Fig. 1), the outputs of which are arranged to feed a common heating water line 10, 12, are cumulatively added or subtracted to increase or decrease in steps the total heating output in dependence upon the output of a control unit RC including a bridge circuit in which are connected a thermistor T<SP>1</SP> responsive to boiler outlet temperature, a thermistor T<SP>2</SP> responsive to outdoor temperature and a control potentiometer. Respective gas valves V<SP>1</SP> to V<SP>4</SP> are operated sequentially each being first opened to a half-way position and then modulated automatically to smooth out the step increase or decrease so that the total heating output follows a heating load demand curve Fig. 2 (not shown) determined by outdoor temperature. A timer T (Fig. 3) operates a switch 40 to reverse every 36 hours the order in which the boilers are brought into operation, whereby to share operating time equally amongst the boilers. In Fig. 3, the control unit RC controls the angular position of the shaft of a motor MA coupled to a potentiometer which controls a motor MB whereby the shaft of motor MB follows the angular position of the motor MA shaft. The angular position of the shafts, is thus related to the heating demand signal from unit RC. The shaft of MA carries potentiometers AP1, AP2 and cams AC1, AC2 for operating switches S1, S2. The shaft of MB carries potentiometers BP3 BP4 and cams BC3, BC4 to operate switches S3, S4. The switches are connected to respective gas valves via a double throw relay SR-36. The pots are connected respecitvely to the valves via respective D.T. relays R1 to R4 for modulating the respective valve postions. OPERATION. When switch 40 is closed by timer T all the relay coils are energized so that depending upon which switches S1 to S4 are closed by the cams, the corresponding valves are opened, each initially to a "half-open" position which results in approximately half capacity output from the respective boiler; the respective valve control potentiometer e.g. AP2 having moved through half its range. The motors then drive the potentiometers in one or other direction to modulate the valve positions of all of the boilers which are operating until the total boiler output meets the demand. The cam switches are arranged to open at a different angular position of the motor shafts when taking boilers off load than when putting them on load. The sensors T1, T2 may alternatively be bulbs actuating bellows to move potentiometers. Alternatively the control arrangement may be applied to cooling units (not illustrated).
