Abstract: 1,034,763. Delivering measured quantities of liquid. MACKIE & CARNEGIE (BARFITTERS) Ltd. May 20, 1965 [Feb. 21, 1964], No. 7296/64. Heading B8N. A device for dispensing measured quantities of liquid, such as beer, comprises a pair of inflatable resilient bags 15, 16 mounted within a container 10 and connected with conduits 13, 14 respectively. The container 10, which may be of stainless steel, is made from two parts 11, 12 screwed together so that the volume of the container may be varied by partially unscrewing the portion 12 or vice versa. In operation, the conduit 13 may be connected to a pressurized supply of beer and the conduit 14 to a dispensing tap and, by opening a valve, the bag 15 is filled with beer and expands into contact with the interior of the container thereby deflating the bag 16. By reversing the position of the valve, beer is fed into the deflated bag 16 thus causing the beer in the bag 15 to be dispensed. In an alternative arrangement using two devices, Fig. 2 (not shown), the bags 17, 18 are interconnected by a pipe having a throttle valve 19, the bag 18 being filled with a liquid such as water. Beer is then fed into the bag 21 thereby causing the water to be forced through the valve 19 into the bag 17 and so dispense the beer in the bag 20. By adjusting the valve 19, the speed at which the water passes from one bag to another may be varied thereby controlling the degree of froth formed.

Title: Means for feeding material to injection moulding machines
Inventor: TUPPENY NORMAN CYRIL
IPC: G01G19/00
Filed: 1955-03-18
Abstract: 796,596. Injection-moulding machines. CLIFFORD COVERING CO., Ltd. March 16, 1956 [March 18, 1955], No. 7927/55. Class 87(2). [Also in Groups XVIII and XXXV] An automatic weighing-machine feeds batches of material one after another to the injection cylinder, each batch being slightly less in weight than that which will suffice to keep the cylinder filled : and when the charge in the cylinder is depleted the injection plunger operates an electric switch which causes a small excess of material to be fed to the cylinder. The Figure illustrates a machine having a vertical injection cylinder 6 in which reciprocates a plunger 7. The cylinder has a port 8 through which material is fed by a shoot 9 from a weighing machine comprising a weigh pan 10 supported by automatic load counterbalancing mechanism. The pan is fed from a hopper 11 by means of a vibratory feed tray 12. A discharge flap 13 at the bottom of the weigh pan is opened and closed by a solenoid 14 under the control of a switch 15. A supplementary hopper 17 has a discharge flap 18 opened and closed by a solenoid 19 under the control of a switch 20. In normal operation, i.e., when the cylinder is not greatly depleted, the plunger 7 reciprocates without actuating the switch 20. When the plunger reaches its uppermost limit, as shown, it actuates switch 15 to de-energize solenoid 14, whereupon flap 13 opens and a lighter-thannecessary batch of material falls down the shoot into the cylinder. As the plunger moves away from switch 15 the solenoid 14 is energized to close flap 13 and also a circuit is made to the vibratory feed tray 12, whereby more material is fed to the weigh pan. When a predetermined amount of material has been fed into the pan, a switch 16 is operated to stop the feed. When the plunger rises again, this sequence of operations is completed. When, however, the plunger descends so far that it operates switch 20, solenoid 19 is energized to open flap 18 to feed an excess amount of material into the pan. Switches 21, 22 prevent material being fed to the cylinder if the plunger makes a short stroke.
