Abstract: 604,368. Washing granular material. DIRECTIE VAN DE STAATSMIJNEN IN LIMBURG. May 22, 1945, No. 12793. Convention date, Sept. 21, 1942. [Class 82(ii)] In a process for the washing of coal by the sink and float method in an unstable suspension, the suspension is retained in the tank (except for that removed on the material or by the discharging devices) and is maintained by the agitation set up by the devices employed to remove the products, the current flowing towards the entrance being directed upwards by, for example, a directing plate. As shown, a tank 2, containing an unstable suspension, which may be sand, magnetite or loess in water, has two conveyers 3, 4 for the removal of floating and sunk products respectively, the movement of these conveyers causing a current to flow in a clockwise direction, and a director plate 14 at the feed delivery end of the tank causing an upward current of the suspension to meet the descending feed. The current may be regulated by varying the depth of immersion of the conveyer 3 or the speed of either or both conveyers. Specifications 466,964, 528,590 and 633,684, are referred to.

Title: Improvements in or relating to thermionic valve circuits
IPC: H03B5/10
Filed: 1922-05-09
Abstract: 195,546. Hecht, N. F. S. May 9, 1922. Thermioreic oscillation generators. - In order to prevent overheating of the anode of a power valve should it cease to generate oscillations, a condenser is inserted in the positive lead of the high-tension Supply and is shunted by an auxiliary valve which functions to discharge the condenser periodically so long as the power valve is oscillating. If oscillation stops, the condenser cuts off the high tension supply. The power valve 1 feeds the oscillating circuit 4, 5 which is back-coupled to the grid coil 6. A reversed coil 11, coupled to the coil 4, throws the grid of an auxiliary valve 10 alternately positive and negative so long as oscillations persist in the circuit 4, 5. Pulses of high tension are therefore fed to the plate of the valve 1 across the condenser 9 so long as this is intermittently discharged through the conductive path afforded by the valve 10. Should oscillation cease, the valve 10 becomes non-conductive and the condenser 9 blocks the high-tension supplycircuit.

IPC: H05B6/10
Abstract: 131,575. Mordey, W. M. May 8, 1918. Heating by electricity. -A method of heattreating iron or steel or their alloys consists in arranging the metal in the magnetic circuit of an alternating current electro-magnet, thereby heating it to the desired degree limited by the critical non-magnetic temperature. For treating articles such as tools, the article may be heated against poles f<1> and allowed to drop into a quenching-bath o when the critical temperature is reached. A portion of an article may be heated either by applying the magnet to such part only, or by attaching to the remaining part a metal holder to keep it cool. The depth to which the article is heated may be controlled by varying the frequency. An indicating-instrument g is placed in the circuit of the magnet winding to indicate the attainment of the required temperature by the change in the magnetic conditions.

Abstract: 132,048. Story, H. J., and Pugsley, A. H. Sept. 9, 1918. Spray carburettors.- The casing B contains a fixed choke-tube E into which the nozzle A projects, and a vertically adjustable choking cone F which controls the passage around the nozzle and also extra air ports D in the casing. The cone F may be adjusted by means of a cam on a controlling lever mounted on an axle on the exterior of the casing, but the adjustment is preferably effected against a spring H through helical slots B<1> with which anti-friction rollers on the cone engage, the cone being rotated, so as to move vertically, by a handle J. Air enters below the cone at C, and also through the slots B<1>, but may enter solely through the latter. A screw P limits the upward movement of the cone F. In a modification, the fuel nozzle is surrounded by a casing provided with holes for the inlet of air and the outlet of mixed air and fuel, and the cone F slides over the casing and determines which holes are in action. A second casing may be rotatably mounted inside the first to control the outlet apertures. The fuel valve K is pressed by a spring K<1> against the end of a spindle L<1> the adjusting head L of which is enclosed in a casing L<2>. According to the Provisional Specification, the fuel needle valve extends into the jet orifice from above and is actuated by suction, and in a preferred construction the needle is carried by two tubes with closed outer ends dipsposed concentrically above the orifice. One of these tubes slides within the other and encloses the spring which returns the needle to its minimum open position, which is controlled by a set-screw.

Abstract: 922,923. Prism systems. E. M. WELCH. April 17 1959, No. 13206/59. Class 97 (1). A prism for use in a camera or projector to enable coloured images to be produced from an ordinary black-and-white film comprises four prisms 66, 68, 70, 72 arranged as shown in Fig. 8, prisms 66 and 70 being identical and having angles of 90 degrees 60 degrees 30 degrees while prisms 68, 72 are equilateral. Surfaces 70b 66b are silvered and two corners are cut off and rendered opaque so that the light transmitted through the prism assembly 60 (Fig. 3a) must be reflected at three surfaces. In Fig. 3a light from an object passes through a dove prism 26 which (a) rotates the image through 90 degrees and (b) reverses the leftright orientation a lens system 24, then inverts the images. The light passes through one of two filters S4 green-blue and S6 red-orange and enters the prism assembly 60. The refractive index of the prism is such that the light rays are totally internally reflected at surfaces 72b, 70c or 68b, 66c. On emerging from the prism assembly they form two adjacent images which are inverted, half the size of the image which would have been formed by the lens alone. In order to produce a stereoscopic effect a barrier 98 (Fig. 3) may be placed in front of the lens system 24 and the two lens components thus produced form dissimilar images which by using a suitable projector i.e. one which makes the images overlap and polarizes them give a stereoscopic effect. In order to prevent any accidental overlapping a barrier may be used in the projector and camera in front of the filters and film.

Abstract: 1535370 Controlling light INTERNATIONAL BUSINESS MACHINES CORP 1 April 1976 [9 May 19751 13280/76 Heading G2F Two or more separately addressable magnetic bubble array layers each of different thickness are stacked in series along a common optical path whereby the Faraday effect produces local phase and/or polarization modulation in incident polarized light to an extent determined by the thickness of those layers which locally contain bubbles. A subsequent analyzer may be provided for intensity modulation e.g. to form a spatial filter or a twodimensional display. Alternatively the bubble patterns may be read holographically without an analyzer for a three dimensional display or a complex spatial filter. A fly's eye lens or single magnifier may be pre-set at the output side of the stack of layers. The bubble patterns in the layers may be controlled by the output of a keyboard or computer, and/or by the output (modified if desired) from a television camera which may view a fixed pattern, or the beam incident on the stack if it bears an image, or the output beam from the stack (the last two options via beam splitters). A rotating mirror synchronized with the camera scanning may enable the camera to view more than one such image. In addition provision may be made to control the pattern signals before application to the stack e.g. for vertical or horizontal shift, rotation, expansion or contraction. In a second embodiment, a holographic image is transmitted over a television system for 3-D viewing at a receiver incorporating the stack. The bubbles in each layer may be produced from a single generator and follow a boustrophedral track or these may be a column of generators one for each row of the array. Each magnetic bubble structure layer may be provided with its own bubble propagation circuit or pairs of adjacent layers may have a common circuit, and the bubble structure layer may be formed of a garnet, orthoferrite or amorphous material. Quartz layers or air-gaps may be incorporated into the stack.
