Title: Improvements concerned with water sterilizers
IPC: A61L2/24
Filed: 1950-04-18
Abstract: 678,743. Water sterilizers. GREVILLE, E. G., and HICKMAN, F. C. April 18, 1951 [April 18, 1950], No. 9494/50. Class 49. In a sterilizer for water or saline water, the flow of liquid from the container to the outlet cock is controlled by an auxiliary valve and the inlet valve is associated with means which close automatically the auxiliary valve when the inlet valve is opened, and there is provided means dependent on the pressure or temperature in the liquid container to open the auxiliary valve when sterilizing of the liquid in the container has been completed. Water is led by a pipe 2 having a stopcock 3 into a closed container 1, is there heated, and is afterwards drawn off at a cock 8. An auxiliary valve 9 between the container 1 and the cock 8 is maintained closed by an electromagnetic device 10 while sterilization of the water in the container is being effected. On turning the spindle 4 of the inlet cock 3 to charge the container, a cam 5 on the spindle depresses an arm 6, which closes electrical contacts 15 and 16 and allows current to flow through leads 13 and 14 to close the electromagnetic device 10 in the valve 9, and so prevents drawing off of water by the cock 8. When the container has been charged, valve 3 is closed by operation of the spindle 4, but the arm 6 is held by a latch 20. When the water has been heated sufficiently, the pressure (e.g. 10-18 lb./sq. in.) in a tube 31 actuates a bellows 30 to depress an arm 29 and close electrical contacts 26 and 28, current flows through leads 24 and 25, coil 23 of an electromagnet 22 is energized to attract the latch 20 and release the arm 6, the electromagnetic device 10 is thereupon de-energized and the valve 9 opened, and consequently water can be drawn off at the cock 8. If detection of the temperature to which the liquid in the container is heated (e.g. 212‹ F.) is by a thermostat bulb 32, depression of the arm 29 and consequent opening of the valve 9 is delayed for the period necessary for sterilization at this temperature of the water in the container (e.g. 15 min.) by the interposition of a time switch 33.

Abstract: 967,780. VTOL/STOL aircraft. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. June 11, 1963 [March 15, 1962], No. 9976/62. Heading B7G. An aircraft comprises a wing having upper and lower parts 5b, 5a, at least one spanwise extending vane 12 or 13 rearwardly of the lower part, and a plurality of jet propulsion units 6 (for example by-pass gas turbine engines, or ducted fans) mounted between the parts, which define an air inlet, the upper part 5b and at least one of the jet propulsion units being pivotable about a spanwise axis 9 to increase the inlet area and divert the propulsive stream over the vane so as to provide direct jet lift on the aircraft. When the upper part is tilted and the inlet area increased, a flow of air is induced between the wing parts, and the thrust is increased. Preferably, there is a series of vanes which tilt as the upper part of the wing tilts, to divert the flow downwards. The vanes may also be tilted to vary the direction of the thrust and to provide lateral control in low speed flight. A series of pivoted vanes 38 (Fig. 13) may also be fitted in the inlet and both series may be shaped to form convergent-divergent passages. In this embodiment doors 40, 41 are provided in the upper part 5b. In another embodiment (Fig. 14), two rows of ducted fans 21a, 21b are fitted, one row 21a being fixed to the lower part of the wing, and the other 21b being fixed to the upper part, so that when the upper part is tilted the downwardly directed efflux from the fans 21b deflects the efflux from the fans 21a. Alternatively, the fans may be side by side, alternate fans being fixed to the upper and lower parts. The fans may be powered by gas generators driving turbines on the hubs or tips of the fans, and downwardly directed control jets may be provided (e.g. in the nose).
