Filed: 1959-04-10
Abstract: 880,835. Valves. BOVING & CO. Ltd. March 30, 1960 [April 10. 1959], No.12182/59. Class 135. Upon turning the offset shaft 10 of a butterfly valve 9 to the closed position the upstream pressure acts over the whole area of corrugated diaphragm 6 i.e. over both areas C, M and since area C is larger than area M a force is produced which deflects the diaphragm and rocks radial spokelike levers 11 clockwise about their fulcra 12 so urging the outer spherical surface of a stainless steel sealing ring 5 against the seat 3. The inner part of the diaphragm may be supported by pieces 15 forming radial extensions of the levers 11. To open the valve, upstream pressure is admitted behind the diaphragm by a by-pass valve, not shown, balancing the pressures on each side of the area C but since packing 21 delays the outward flow of fluid to the space behind the area M the pressure acting on the front side thereof rocks the levers 11 anticlockwise to move the ring 5 whereupon the valve may be opened by turning shaft 10. The fluid admitted behind the diaphragm may be other than the controlled fluid e.g. compressed air. The ring 5 may be spring-loaded. The levers 11 may be rocked through a common thrust ring moved axially by hydraulic pneumatic or mechanical means extending through the shaft 10. The diaphragm may be mounted by its outer periphery in the wall of the valve casing and the butterfly valve may have an interrupted sealing ring.

Abstract: 514,060. Radio receiving sets. PLESSEY CO., Ltd., PACKMAN, P. J., and MORRISON, P. H. April 23, 1938, No. 12230. [Class 40 (v)] [Also in Groups XXXVIII and XXXVI] In a push button system for controlling the tuning of radio sets, each button is allocated to predetermined positions of both the tuning device and the wave range switch. The tuning device and the wave range switch are driven by a common motor 12, Fig. 5, under the control of selector switches A, B the stationary contacts 25, 70 of which are connected to the push buttons 80 ... 84. Groups of buttons, 80, 81 correspond to the long and medium wave bands respectively and the keys 82, 83, 84: effect selection of short waves, very short waves and gramophone reproduction. When a key in a group 80 or 81 is operated, a circuit for the motor 12 is closed over one or other contact 64 or 65 of the switch B and the motor is driven in one or other direction to position the waverange switch until the circuit is broken by the insulating gap 66. The switch A associated with the tuning condenser is rendered ineffective by a switch 73 ... 76 operated by one or other of the clutch magnets 49, 50 which is operated over the contacts of switch B to clutch the switch to the motor. When the wave-range switch is correctly positioned, the clutch is released and the switch 73 ... 76 places the motor 12 under the control of the switch A which is then positioned in accordance with the operated key. The switch A is driven through friction gearing and the contacts 25 are adjustably mounted on supporting frames. Specification 454,735, [Group XXXVII], is referred to. The Provisional Specification also refers to Specification 501,273, [Group XXXVIII]. Reference has been directed by the Comptroller to Specification 197,774.

Abstract: 1362139 Exposing photo-sensitive material; eliminating diffraction effects INTERNATIONAL BUSINESS MACHINES CORP 16 March 1972 [6 April 1971] 12230/72 Headings G2A and G2J In exposing a photo-sensitive layer 50 through a mask 30 light rays are caused to fall on the mask from different directions simultaneously or successively so that diffraction patterns occurring in the plane of the layer are shifted by a distance sufficient to prevent side maxima from fully exposing the layer. Fig. 4 shows one embodiment of apparatus used in carrying out this method. Four light sources 21-24 arranged at the corners of an imaginary square and having condenser lenses 25- 28 associated therewith are excited either simultaneously or successively thereby causing inclined parallel beams of light to fall on the mask 30. The diffraction patterns generated by the individual light sources will be displaced relative to one another, preferably by half the distance between two neighbouring side maxima. In another embodiment Fig.5, (not shown), the apparatus comprises a light source (60), a first lens (61), a reflecting surface rotatable about the optical axis of the first lens and on which surface the first lens forms an image of the light source, and a second lens (64) arranged to direct light from the reflecting surface on to the mask, the light source and the reflecting surface being spaced from the first lens (61) by twice its focal length, and the reflecting surface and mask being spaced from the second lens (64) by a distance equal to its focal length. The reflecting surface is formed by two reflecting right-angle prisms (62, 63). The prism pair can be rotated in steps or continuously. Mono -chromatic light is preferably used.

Abstract: 782,506. Underground gasification of coal. COAL INDUSTRY (PATENTS), Ltd. June 17, 1955 [April 29, 1954. No. 12426/54], Drawings to Specification. Class 55 (2). [Also in Group XXVI] In the underground gasification of coal heat from the upcast gas is turned into shaft power in a heat engine and is also used to preheat the downcast air which goes to the underground gasification zone. The stream of upcast gas may pass as working fluid to and be burnt in an internal-combustion engine or gas turbine plant, the exhaust being used to preheat downcast air. In a modification some of the upcast gas may be bled off before the heat engine and burnt to pre-heat the downcast air. When at a high temperature the upcast gas has to be cooled before reaching the heat engine and it is first passed through a heat exchanger which preheats the downcast air. These three arrangements may be used separately or in any combination.
