Title: Improvements in and relating to automatically closing rinsing valves
IPC: E03D3/04
Filed: 1930-04-07
Abstract: 352,406. Fluid-actuated valves. BENKISER, E., 19, Giesshausstrasse, Ludwigsburg, Germany. April 7, 1930, No. 10966. [Class 135.] In an automatically closing valve, particularly a rinsing valve, comprising a counterpressure chamber 6 and an auxiliary valve 12 in the main valve member 7, the counter-pressure chamber, in which the main valve member moves, is conical on the outside and is rotatably mounted in a housing 4 screwed to the valve casing 3. The hollow conical member 5 forming the chamber 6 is provided with a groove 19 on its outer surface, which groove communicates with the chamber 6 through a bore 18 in the member 5 and with the supply pipe 1 through passages 20, 21, 22. A tapering conical groove 21 in the member 5 communicates with vertical grooves 20, 22 in the hood or housing 4 and the member 5 and thus controls the flow of pressure fluid from the supply pipe 1 to the chamber 6. The upper part of the member 5, which is provided with wings 24 engaged by a pin 26 attached to a rotatable graduated ring 25, is screw threaded and engaged by a cap 28 provided with actuating holes 30 and also carries a screw 27 for adjusting the lift of the main valve 7. A rubber pad 29 in the cap 28 seals the arrangement. The valve member 7, which has a facing 9 of rubber, is provided with a piston portion 8 moving in the cylindrical chamber 6 and is pressed towards its seat 10 by a spring 17. It is also provided with an axial bore and a tubular screwed extension 14 housing the auxiliary valve 12 and its winged guiding pins 11, 13. The upper end of the extension 14 is provided with V-notches and an adjustable hood 16 for regulating the outflow through the auxiliary valve 12. A lifting bush 31 having a star-shaped jet and a tubular portion 33 for engaging the auxiliary valve 11 is operated by a pivoted forked lever 36, 37, 38 and also carries a plate member 34 at its upper end, movable in an aperture 35 in the casing so as to keep this aperture from getting clogged and to guide the member 31. In operation, the lever 37 is depressed and the auxiliary valve 12 is raised. Further movement of the lever 37 raises the main valve 7 at a rate dependent upon the opening of the notches 15. The lever 37 is then released and fluid enters the counter-pressure chamber 6 through passages 22, 21, 20,18 and closes the main valve at a rate dependent upon the opening of the passage 21. The degree of opening of the passage 21 is set by rotating the graduated ring 25 and, with it, the member 5 to the desired extent and then securing the ring in this position by tightening the cap 28. Atmospheric pressure exists in the space 32 through the opening 35 so that the valve seats itself without shock, and back flow of impure liquid, in the event of reduction in pressure in the supply pipe, is prevented.

Title: Improvement in and relating to means for absorbing and diverting the energy of marine waves
IPC: F03B13/20
Filed: 1943-07-14
Abstract: 607,115. Floating breakwaters. LOCHNER, R. A. W. A. July 14, 1943, No. 11439. [Class 68 (ii)] A floating breakwater unit for absorbing and diverting the energy of marine waves has a mean draught not less than 10 per cent of the maximum length of the waves, and has natural periods of roll, pitch, and scend which are greater than the natural period of the waves. The latter effects are obtained by combining great mass with small water plane area, and arranging the mass so that the roll is very long, so that the average mass resisting motion per unit of draught is greater than the mass of water displaced at the water line per unit change of draught. Great mass may be imparted to the apparatus by flooding certain portions and arranging the shape so that surrounding water is carried with the apparatus when it oscillates, and by constructing the unit so that the centre of mass is as close as possible to the centre of wave pressure the effect of the waves is decreased. Fig. 1 shows an apparatus of cruciform cross-section, the upper arm 2 consisting mainly of buoyancy compartments, but with certain compartments 8 which may be flooded, and the immersed side and lower arms 3 4 being filled with water through holes 6 and 7. The unit has faired ends to aid towing, mooring links 9, fairleads 10, bollards 11 and deck 13. For,waves 8 ft. high and 200 ft. from crest to crest suitable dimensions are: length 200 ft., dimensions A and B of Fig. 1 25 ft., draught 20 ft., and weight, including water, 1000 tons. The embodiment shown in Fig. 4 comprises a hollow cylinder with outer and inner walls 17, 18, with the annular space between the walls filled with air, and the central space with water. The mean draught is about two-thirds of the greater diameter, and longitudinal fins may be fitted to trap water. A single line of units end to end, or multiple lines one within the other may form a harbour.

Title: Improvements in or relating to corner reflectors
Inventor: COLLIS RONALD THOMAS HARRY
IPC: H01Q15/18
Filed: 1956-04-16
Abstract: 818,454. Radio reflectors. DECCA RECORD CO. Ltd. July 16, 1957 [April 16, 1956], No. 11541/56. Class 40 (7). Corner reflectors and clusters of four or eight ' such reflectors are formed from separable triangular units each having a frame of resilient material which maintains in tension a sheet of flexible reflecting material secured thereto. As described, the frames are made of aluminium alloy wire and are in right-angled isosceles triangle form, the sides being initially bowed outwards. The two ends of the frame wire may be butt welded or secured together in a tube by crimping. Alternatively, the frames may be formed of a resilient plastic material. To cover the frame, metallized mesh, metal foil, or metallized paper is spread over a triangular jig and the frame forced into position inside the upstanding sides of the jig. The covering material is then folded over the frame and the edges stuck down to the main body of the covering. On releasing the unit from the jig the bowed sides of the frame maintain the covering in tension. It is preferred to cut away the covering adjacent the angles of the frame and the finished unit will be as shown in Fig. 4. It is convenient to make two sizes of unit, one of half the area of the other and when clipping the units together a projection 17 at the mid-point of the longer side of the larger unit is useful. The projection may conveniently be a wire doubled back on itself and soldered to the tube holding the ends of the frame wire together. In the construction of a cluster of four comer reflectors (Fig. 5), three large units 20, 21 and 22 are placed with their longer edges together and secured to each other by spring C-shaped clips at their ends. As shown, units 21 and 22 are in a horizontal and unit 20 in a vertical plane. Next two smaller units 23 and 24 are placed in a common vertical plane perpendicular to unit 20 and on either side thereof to complete the structure. A special four-armed clip (Figs. 7 and 8, not shown) is used to secure together the lower corners of units 23 and 24 and the bottom corner of unit 20 and the right-angled corners of the smaller units are secured by C clips to the central projections on the longer sides of the larger units. By clipping on one larger unit and two smaller ones above the units 21 and 22 a cluster of 8 reflectors may be formed. A larger cluster of four reflectors formed from eight larger units is described with reference to Fig. 6 (not shown). The clusters may be formed with their horizontal surfaces of mesh to minimize air resistance when the reflector is to be carried upwards by a balloon and the vertical surfaces of foil or metallized paper which are cheaper and better reflectors. Specification 818,455 is referred to.
