Title: Improvements in swimming belts, life belts and similar appliances
IPC: B63C9/125
Filed: 1923-06-23
Abstract: 220,120. Mierre, B. A. F. de, Mierre, C. W. H.. E. de, and Cousans, F. June 23, 1923. Storing under pressure.-In inflatable life-belts &c. adapted to be inflated from a gas-filled cartridge, pierced when required, the cartridge is screwed into a tubular member or nozzle provided with a piercer of drill or other type, and piercing is effected by rotating either the cartridge or the tubular member, or by a spring released by a trigger. The cartridge 7 is held in a pocket 6 by a clip 8 slidable along a bar 12 one end of which engages flats on a nozzle 15 secured to a float 3, and prevents rotation of the cartridge. A sleeve 26 formed externally as a bobbin has right- and left-hand threads engaging corresponding threads on the cartridge and nozzle 15. The interior of the sleeve carries a piercer 28 on a spider 29, and is fitted with washers 27 to make gas-tight joints when forced against the ends of the cartridge nozzle. The piercer is operated by pulling a cord 30 wound round the sleeve 26, thus rotating the sleeve so that cartridge and nozzle 15 are moved inwards by the screw threads. A cord 14 serves to support the device on the neck of the wearer. A non-return valve 64 is provided in nozzle 15. In modifications, the cartridge is of flattened form and held against rotation by a flap pocket or correspondingly shaped clip. In another form, the sleeve 26 is omitted, the cartridge screwing directly into a nozzle provided with a piercer. In this form the operating cord 30 is arranged round the cartridge, which is also provided with a thumb-piece so that it may be screwed home by hand. Trigger released modifications are also described in one of which the piercer is driven against the cartridge by a spring in compression, and in another the piercer is advanced by a spring-rotated threaded member. The trigger may be replaced by a press or pull button.

Title: Improvements in or relating to windscreen wipers
IPC: B60S1/38
Filed: 1957-05-24
Abstract: 888,566. Windscreen wipers. O'SHEI, W. E. May 14, 1958 [May 24, 1957], No. 16554/57. Class 138 (1). In a windscreen wiper including a squeegee 1, which has a continuous wiping edge, thickens towards the other edge 2, and is held by pressure distributing holders 6 and 6a, the element 1 is weakened at zones opposite the points where the holders 6 and 6a grip it. This permits the portions of the wiping edge opposite the pressure points to rock or flex to a trailing position, as the wiper reciprocates over the windscreen, more readily than the other portions of the wiping edge, and this improves the distribution of pressure over the windscreen. The particular method of weakening proposed is the formation of grooves 13 in the squeegee at the pressure points. Specification 888,565 is referred to.

Abstract: 1,145,568. Purifying water by freezing. SING-WANG CHENG, and CHEN-YEN CHENG. 14 March, 1967 [15 April, 1966], No. 16600/66. Heading F4H. A freeze-purification process for aqueous solutions, e.g. sea-water, employs a heatexchange medium which, under a relatively low pressure, is melted while absorbing the heat of freezing of the ice and, under a relatively high pressure, is solidified while supplying the heat of fusion of the ice. As shown, sea-water is filtered, heat exchanged with concentrated brine and product water, refrigerated and passed to an ice maker in which it is directly contacted with a slurry of a solid organic material under low pressure. The resultant ice, concentrated brine and organic liquid pass to a separator S 1  from which ice and brine are withdrawn by a pump J 1  and passed to an ice-washer. Part of the organic liquid from S 1  is passed to a highpressure ice melter by a high pressure pump J H  and the remainder slurries the ice from the icewasher, this slurry being passed by a lowpressure pump J L  to a set of vessels O 1 -O 4  in which it is pressurized by high-pressure streams of fresh water and organic slurry from a separator S 2  downstream of the ice melter, the pressurized slurry being supplied to the ice melter. The fresh water and organic slurry streams from vessels O 1 -O 4  are now at low pressure and are respectively removed as product and recycled to the ice maker. The heat exchange medium may be a pure compound or a eutectic or other mixture of substances; suitable media are listed.

Filed: 1950-07-06
Abstract: 671,801. Cylinders: regulating.ERICSON, G. R. July 6, 1950, No. 16885/50. Classes 7(ii) and 7(vi) The compression ratio and valve timing of a multi-cylinder engine are varied by turning the cylinder block 19 about a camshaft 15, mounted in the crankcase 12 and controlling inlet valves 23, the block 19 being turned under the joint action of mean effective cylinder pressure and of variations in intake manifold vacuum transmitted to a fluid motor 62. As shown. the camshaft 15 controls also exhaust valves 25, and the motor 62, which is connected to the intake manifold 29 downstream of a carburetter throttle valve 33 by a pipe 64, acts on a piston 61 controlling through links 58, 52 a shaft 46 journalled in crankcase bearings 47 and having eccentrics 48 working in elongated bores in lugs 51 on the block 19 to turn it about the camshaft 15 via bearing brackets 35, of which there may be two (as shown) or more. Instead of a plurality of eccentrics 48 one, preferably centrally situated, may be employed. Flexible sealing strips 38, 44, 45 are provided between the block 19 and crankcase 12, and the block has a cover 20 formed with heads 22 for each cylinder. Gears 18, 16 drive the camshaft 15 from the crankshaft 14. In the position shown in Fig. 3, the engine is operating with very little intake vacuum, as under maximum load conditions, and the mean effective cylinder pressure has tilted the block 19 to give a low compression ratio. On increase in intake vacuum, as with decreasing load, the piston 61 is drawn up in the motor 62 until finally the flange 42 abuts the crankcase 12, the compression ratio then being at its highest. The weight of the block 19 acting about the camshaft 15 assists the motor 62 to overcome the cylinder pressure. The movement of the block 19 about the camshaft '15, is such as to cause the inlet and exhaust valves to open and close later as the compression ratio increases.
