Title: Apparatus and method for generating artificial fog
IPC: F02C6/04
Filed: 1961-04-04
Abstract: 925,277. Apparatus for generating artificial fog. BMW TRIEBWERKBAU G.m.b.H. April 4, 1961 [April 2, 1960], No. 11974/61. Class 81 (1). Apparatus for generating artificial fog comprises a jet turbine engine having a compressor 1, combustion chamber 2 and a turbine 3 for driving the compressor and means 5 for introducing into and evaporating or burning in the exhaust gas jet of the turbine engine a fogproducing material, preferably a combustible material such as gas oil for the generation of artificial fog. As shown in Fig. 1 the hot turbine exhaust gases issued from a tube 4 in which an attachment 5 is provided comprising injection nozzles for the combustible substance as well as ignition means; for reducing the temperature of the turbine exhaust gas, fresh atmospheric air may be introduced into the exhaust jet through openings 6 in the tube 4. The combustible substance e.g. gas oil introduced into the exhaust gas/air mixture and atomised for instance by a fan in the accessory attachment 5 is ignited by the accessory equipment and evaporates or burns with the formation of smoke. As shown in Fig. 2 the combustible substance is directly injected into the exhaust gas by injector nozzles 7 inside tube 4 and is ignited and evaporated or burnt in the exhaust gas to form a smoke. If required the volume of air flowing through exhaust tube 4 may be increased by the provision of openings 8 for the passage therethrough of additional air from the ambient atmosphere.

Abstract: 1,086,731. Flash-type evaporators; distillation of water. AMERICAN MACHINE & FOUNDRY CO. March 15, 1965 [March 23, 1964], No. 12180/64. Heading BIB. In a flash evaporator divided into stages by partitions 11, the liquid being evaporated enters each stage through an upwardly-directed converging passage bounded on one side by a plate 18 which extends longitudinally through the stage, a horizontal plate 19 with a downwardly-inclined lip 20 being mounted over the plate 18 forming an elongated outlet from which the liquid passes across the stage in the form of a sheet of particles and partially flashes into vapour. The vapour flows through openings 21 which lead to a condenser (not shown). Heated liquid enters the first stage through aperture 13, and the unevaporated liquid pases from stage to stage through apertures 23. The apparatus may be used for the distillation of water. Each passage is formed by a side wall of the evaporator and the plate 18, which is preferably inclined at an angle of 7‹ to 25‹ with the side wall. Lip 20 should form an angle of 7‹ to 30‹ with plate 18. An evaporator wherein each stage has two converging passages is also described.

Title: Improvements in or relating to electrical circuit arrangements
Inventor: BERTH-JONES ERIC WOLLASTON
IPC: G06G7/28
Filed: 1958-04-17
Abstract: 915,271. Non-linear circuits. ELECTRIC & MUSICAL INDUSTRIES Ltd. April 17, 1959 [April 17, 1958], No. 12208/58. Class 40 (6). [Also in Group XXXVI] An output voltage which is a non-linear function of an input voltage is obtained from a ladder network each shunt branch of which comprises an impedance element and a switching element in series. The impedance elements comprise resistors R 2 , and the switching elements diodes D 1-n  which are so biased as to become successively conductive. The graded biases which are required are obtained by splitting the series elements of the network into two chains, the one (1-#)R 1  in one series arm and the second #R 1 , which provides the bias, in the other, being earthed at one end and having a bias voltage applied to the other over a resistor R<SP>1</SP>. The terminating resistor is similarly divided into separate components (1-#)R 0  and #R 0 . If the factor # is appreciable, the system may be earthed at its true neutral point by also splitting the resistors R 2  into components (1-#)R 2  and #R 2  and taking the earth to the join of these (Fig. 2, not shown). In an alternative embodiment (Fig. 4, not shown), the series elements R 1  are not split up, but the diodes are biased instead from individual voltage-dropping resistors of relatively high value. The arrangement may be fed from a potentiometer in the cathode circuit of a cathode follower (Fig. 5, not shown).

Abstract: 273,060. Vose, E. H. May 12, 1926. Traps. - A removable trap for sinks, baths, lavatory basins, &c., comprises a cylindrical vessel 3 flanged outwardly at its upper end and having perforations 6 at some distance from the bottom 5, in combination with an inner openended imperforate tube 8 of smaller dimensions immovably connected at its upper end through a water seal to the cylindrical vessel 3 above the perforations 6 and projecting downwardly below the perforations so that its end may be sealed by liquid retained in the outer vessel 3. The trap is of metal, earthenware, or other material. It fits loosely into the sink 2 with the flange 4 in a recess. Its diameter is less than that of the waste pipe or drain 1. A downwardly turned flange on the inner tube 8 engages an upwardly turned flange or an annular trough 7 on the vessel 3 to form a water seal between the top of the vessel and the perforations 6. A curved or flat grating 10 may be carried on the inner tube 8 or the outer vessel 3. In a modification the parte are made of pressed metal, soldered or brazed together where, necessary. Specification 5888/93 is referred to.

Abstract: 908,450. Transformers. FERRANTI Ltd. March 29, 1961 [April 7, 1960], No. 13309/60. Class 38 (2). In order to give an even surge voltage distribution over an inductive winding the coils are interleaved as shown on the Figure, wherein the winding comprises a group of pairs of disc coils spaced along a common axis (not shown) to the left of the Figure. The group includes initial pairs A, B, intermediate pairs C, D, E, and final pair F. Each disc is wound from three adjacent insulated conductors and the turns are connected in numerical sequence 1-120 as shown. The inner ends of one coil of each pair are connected to the inner ends of the other coil of the pair by cross-connections GHJKLM. The outer ends are connected so that the current path after passing through any intermediate coil pair passes once through each of the two preceding pairs such as B, C (by turns 49 to 54 and 55 to 61), once through the next succeeding pair such as E (by way of turns 62 to 68) once again through the immediately preceding pair such as C (by turns 69 to 74) and then a second time through pair D (by way of turns 75 to 81).

Title: Improvements in discharge-operated electric switches
IPC: H05B41/08
Filed: 1946-04-24
Abstract: 675,262. Thermal switches. PHILIPS ELECTRICAL, Ltd., SELL, E. A. F., HOLMES, T., and MOLL, J. A. M. VAN. Oct. 5, 1950. [April 24, 1948] No. 12356/46. Class 38 (v). In a glow discharge switch the bimetallic strip electrode 6, or one or each of the bimetallic strip electrodes in a switch in which both electrodes are bimetallic, is provided with a metal tube 7 secured in metallic contact with the bimetallic strip at a point between the ends of the latter. The bimetallic strip 6 may be curved as shown and carry a contact 8, the tube 7 being fixed mid-way between the ends of the strip. The tube 7 which is preferably of nickel and cylindrical has a length equal to the width of the strip. In operation, a normal glow discharge occurs between the strip 6 and the electrode 4 and in addition a more intense discharge occurs inside and/or at the ends of the tube. When the contacts 4, 8 close and the glow discharges are extinguished, the strip 6 is prevented from cooling to the temperature at which the contacts reopen until the heat which has been stored up by the tube 7 has flowed to the strip and has been dissipated. This ensures an adequate pre-heating period when the switch is used as a starter switch for an electric discharge lamp.
