Title: Improvements in or relating to electrical oscillation circuit arrangements
IPC: H03L1/04
Filed: 1931-05-23
Abstract: 376,898. Thermostats. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. May 23, 1931, No. 15308. Convention date, May 23, 1930. Addition to 376,893, [Group XXXVI]. [Class 64 (ii).] In compensating for temperature variations of an inductance coil as claimed in the parent Specification, an auxiliary heating current is passed through the coil, or through an associated conductor in heat relationship therewith, means being provided for controlling the duration or magnitude of the heating current. In one arrangement, the inductance coil 4 is connected in one arm of a Wheatstone bridge, the other arms 1, 2, 3 comprising resistances unaffected by temperature variations. The bridge diagonal contains a relay 10 which operates when the bridge becomes unbalanced owing to resistance variations produced by high-frequency currents heating the coil 4. A continuous current source A, B is connected to the bridge through contact 11 of the relay 10 when the bridge is balanced, movement of the relay armature to contact 9 cutting in resistance 8 and reducing the current and consequently the temperature of the inductance coil 4. In another arrangement, the relay 10 closes the circuit of a main relay which connects the heating current, a further relay being provided for intermittently closing the circuit of the main relay independently of relay 10. The third relay may be energized by the charge and discharge of a condenser through a glow discharge tube. Instead of continuous current heating, the auxiliary source may be low frequency alternating current, with continuous current for the measurement, filters being provided to keep the heating current out of the bridge circuit. The different currents may be kept separate by a duplex connection similar to that used on a telephone quad, continuous current for heating and measurement being employed. Specification 342,976 is referred to.

Filed: 1957-05-15
Abstract: 836,047. Nuclear reactors. PLESSEY CO. Ltd. May 12, 1958 [May 15, 1957], No. 15367/57. Class 39(4). [Also in Group XII] In a liquid-cooled or liquid-moderated reactor gaseous fission products are removed from the liquid by scrubbing with helium. The scrubber comprises a matrix of horizontal prismatic bodies 3 disposed between plates 2, each body having an inlet pipe 4 and an outlet pipe 7 normally closed by a spring-loaded ball-ended rod 5. The prisms are made of plastic material to prevent leakage. To scrub liquid from a given channel or group of channels in the reactor, the appropriate rod 5 is withdrawn and liquid flows out of the prism and downwards through the chamber where it is scrubbed by gas flowing upwards, afterwards returning to the reactor. The gas passes through a separator at the top of the chamber and then through a precipitation chamber where it deposits the fission products.

Abstract: 715,036. Hotplates; gas burners. HOMANN, W., [trading as HERMANN-WERKE W. HOMANN], July 2, 1951 [July 5, 1950; July 5, 1950], No. 15578/51. Addition to 705,410. Classes 75 (1) and 126 A hotplate according to the parent Specification is characterized by the provision of a hobplate having a cut out portion bridged by ribs for supporting a cooking utensil, the ribs extending to the edge of the cut out portion without touching it and being centrally supported by the trough beneath 'the hobplate. The trough 2 is disposed below the hobplate 3 which has a cut out portion 29 bridged by ribs 21 (Fig. 1), carried by a burner cover 15. The ribs 21 are located centrally of the cut out portion 29 by a pin 17 supported within a burner mixing chamber 11 by stays 18. The burner is supported by a cuplike mounting member 5 fitting within an aperture 4 in the trough 2, a gas supply tube 9 and a nozzle 10 being carried by a clip 8 on the mounting member 5. A disc 12 which is integral with the burner closes the top of the mounting member 5 which is provided with air inlets 6 from beneath the trough. Primary air enters the lower part of the mixing chamber through passages 14 and secondary air passes from the mounting member 5 through apertures 19. In a modification (not shown) the ribs are carried directly by the trough. In a further modification (not shown) the ribs are carried by the disc covering the mounting member which is imperforate so that combustion air reaches it from above the trough only.

Title: Improvements in gas valves
IPC: F23N5/20
Filed: 1925-06-16
Abstract: 242,591. Hackstroh, P. A. M., and Keulen, O. van. Nov. 8, 1924, [Convention date]. Safety cut-off valves. - A valve device for supplying gas to a burner adapted to close automatically in the event of the flame being extinguished has a supplementary valve moved into the operative position by the movement of the hand-actuated main valve but normally prevented from closing by a thermally-actuated catch. The supplementary valve 11 co-operates with a seat 12 on the outlet pipe 13 and is carried by a pair of tipping tanks mounted on an axis 5. The tanks which contain liquid or granular material are connected at the top by an air pipe 10 and are cross-connected by pipes 8, 9. The pipe 8 is of larger bore than the pipe 9 so that liquid can flow rapidly from the tank 7 to the tank 6 when resetting the apparatus. On opening the main valve an arm 3 on the main valve engages a slot 4 to tip the tanks so that liquid commences to flow from the tank 6 into the tank 7 through the pipe 8. This transfer of liquid would ultimately close the valve 11, but if the gas is ignited, the heat generated is transmitted through a connection 17 to a capsule 15 to move a catch 16 into the path of the valve 11 and arrest its movement. In a modification, the valve 11 is allowed to close, a further thermally-actuated' valve being arranged to open a by-pass before this occurs.

Abstract: 1,066,053. Transverse-flow fans and pumps. HOOVER Ltd. April 22, 1964 [April 22, 1963], No. 15857/63. Heading F1C. In a transverse-flow fan or pump including a cylindrical rotor having blades extending parallel to its axis and mounted to rotate about its axis, and a divider extending the length of the rotor between a peripheral outlet region and a peripheral inlet region, the divider is formed so that at least some sections of it in planes parallel to the axis deviate from a straight line parallel to the axis. Fig. 1 shows a transverseflow fan comprising a vortex guide 15 separating the inlet region 17 from the outlet region 19, and a cowling 20 extending partially around the rotor 10. To reduce noise due to a compression or suction impulse occurring each time a rotor blade 14 passes the leading edges 18 and 21 of the vortex guide 15 and cowling 20, these edges are inclined or distorted so that the impulse occurring at one point along the length of the blade does not occur simultaneously with those at other points. In this purpose, the leading edges 18 and 21, when viewed in the direction of the arrows A and B respectively, may have a contour comprising one or more helices 32, Fig. 4, four such helices being shown. Instead of helices, shallow circular segments or a sinuous curve similar to a sine curve may be used. The shapes can be inverted. Preferably, the range of angular displacement of points on the contour is at least equal to the angular displacement between adjacent rotor blades.
