Abstract: 602,537. Coin-freed apparatus for supplying compressed air and other fluids. MEACOCK, H. E. Oct. 16, 1945, No. 27084. [Class 27] In apparatus having a relay valve 35 for controlling the fluid delivery, which is for a period determined by a timing device 78, the relay valve is maintained normally closed by pressure fluid supplied to its motor chamber 44 from the inlet side 34 of the valve by way of a flow-limiting construction 47, and is opened for the delivery period by opening an exhaust valve 51 to release the pressure from the motor chamber. The apparatus shown is for delivering compressed air for inflating tyres, the inlet 34 being connected to a compressed air reservoir maintained charged by a motor-driven compressor, whilst the outlet has a flexible hose terminating in a tyre connector incorporating a manual control valve and pressure gauge. The exhaust valve 51 is maintained normally closed by a spring 55, and is opened by a lever 58 connected to a plunger 75 loaded by a spring 79 and controlled by the timing device 78, the latter comprising a pinion 91 meshing with a rack 90 on the plunger and connected by a one-way ratchet pawl 92 with a gear train terminating in an escapement 96. In operation, depression of a handle 28 after insertion of a coin moves the plunger 75 to the right, loads the spring 79 and rocks the lever 58 to open valve 51. This releases the pressure from the motor chamber 44 of the relay valve 35 which opens under the action of a spring 42 so that compressed air can be taken from the hose connected to the outlet. The plunger 75 is slowly returned by its spring 79 under the control of the escapement 96, and, on reaching its initial position restores lever 58 to close the exhaust valve 51. Pressure then builds up in the motor chamber 44 and releases the relay valve to cut-off the supply to the outlet. The period of supply can be varied by adjustment of an end stop 97 for the forward movement of the plunger 75. Coin action, mechanical - connection; fraud, preventing. The handle 28 terminates in a barrel 68 adapted to telescope over the end of the plunger 75. An inserted coin 86 comes to rest between the adjacent ends of the barrel and plunger to form an operative connection between them, and is released over the edge of a support 67 to the till 100 after completion of the forward stroke. The lever 58 is restrained from movement to open the valve 51 until the coin has been discharged and the handle 28 returned, by a lever 106 rocked anti-clockwise by the barrel 68 when displaced; a spring 105 forms the connection between the plunger 75 and valve lever 58, and actuates the valve lever when the lever 106 releases it.

Title: Refrigeration system
IPC: F25B41/04
Filed: 1958-08-27
Abstract: 877,034. Refrigerating. BODCHER, H. F. V. Aug. 27, 1958 [Aug. 29, 1957], No. 27526/58. Class 29 In a compression system a valve 5 between the receiver 3 and the evaporator 6 is opened when the receiver pressure reaches a predetermined maximum and closes when it reaches a predetermined :minimum. In operation, valve 5 being closed, the compressor withdraws refrigerant from the evaporator and supplies it to the condenser 2 and receiver which fills with liquid. Ultimately the condenser also begins to fill thus reducing its effective heat exchange capacity and the pressure rises. This causes valve 5 to open and the receiver empties into the evaporator, the relatively warm refrigerant effecting defrosting, and the resulting drop in receiver pressure causes closure of valve 5. The suction pressure then lowers the refrigerant temperature in the evaporator and the next cycle follows. As shown evaporator 6 discharges into an accumulator 7 from which liquid is led through a check valve 9 and pipe 8 to the evaporator inlet. The evaporator may be protected by a grid. In a modification, Fig. 4 (not shown), the cycle is prolonged by providing a capillary by-pass round valve 5, this delaying the build-up of receiver pressure and a by-pass is also provided between the compressor and the receiver so that, during charging of the evaporator with refrigerant, some hot gas can also pass through valve 5. It is stated that valve 5 may respond to receiver temperature or to condenser temperature or pressure. If the system works under constant thermal load, the valve may be time controlled.
