Filed: 1944-04-19
Abstract: 575,871. Optical apparatus. BOARDMAN, E. April 19, 1944, No. 7230. [Class 97 (i)] An apparatus for teaching optics comprises an outer rectangular box A closed at one end by two spaced partitions having coaxial apertures therein and an inner rectangular sleeve B slidable in the box A and having a translucent screen S fitted at a point one-third to onequarter of the length of the sleeve B from one end, scales being marked on the exterior surfaces. The spaced partitions form a pocket which has notches V for supporting suitably mounted lenses, mirrors, or diaphragms, the plane containing the notches being the base line for the scales on the inner sleeve. In a modification, Fig. 2 (not shown), a Z-shaped piece of metal, inserted into the inner sleeve from the viewing end, has an aperture cut in the end which abuts against the screen ; rays from this aperture after reflection from a mirror held in the notches, form an image on the screen which may be viewed through an aperture in the other end of the Z-shaped piece. The apparatus may be used to demonstrate optical phenomena and for obtaining optical data.

Title: Acetylene
Inventor: GARDNER JOHN BAXTER
IPC: C07C11/24
Filed: 1957-03-05
Abstract: In a process for the separation of acetylene from admixture with other gases by absorption in a selective solvent for acetylene at a temperature substantially below 0 DEG  C. the refrigerant required to cool the solvent to, and maintain it at, the absorption temperature, is derived from liquid methane or liquefied natural gas.  The absorption may be carried out at temperatures of -30 DEG  to -100 DEG C.  The liquid methane or liquefied natural gas which is used for cooling is itself gasefied and may be used in the production of the acetylene by partial combustion. In a preferred embodiment, the liquefied gas passes from a storage vessel 10 through a conduit 11 to an air separation unit 12 to which it supplies the necessary <PICT:0813562/IV (b)/1> refrigeration and is itself vaporized as described in Specification 804,944.  The vaporized gas passes through conduit 13 to a reaction chamber 14 after admixture with gaseous oxygen which comes from the air separation unit 12 through conduit 15. The reaction gas containing 7.8 per cent of acetylene passes to the acetylene absorber and separator 19 in which the acetylene is completely separated by a solvent such as acetone or dimethylformamide.  All the necessary refrigeration is supplied by means of the vaporization and superheating to ambient temperature of the liquid gas.  The gaseous acetylene may be taken to a liquefier 23 where it is liquefied or converted to a concentrated solution in a cold solvent by heat exchange with the liquid gas which is fed to the liquefier 23 from the conduit 20 via a conduit 24.  Acetylene is withdrawn through a conduit 26. The residual gas after removal of acetylene may be withdrawn through conduit 27 and used as a constituent of town gas.

Preventing unauthorized use.-To protect a motor-car against theft the bonnet is fitted inside with a lock d accessible through a keyhole band adapted when locked to shut off the petrol supply to lock the bonnet, to open the ignition circuit, and to set an alarm for automatic operation (a) when the vehicle is vibrated, for example, by anyone jumping on the footboard, or (b) when the doors are opened When the lock d is locked, its bolt moving upwards shoots the bonnet locking bolt h and by means of a pivoted lever e depresses a rod i, thereby shutting-off the petrol supply by turning a cock r, and effecting a furthering locking of the bonnet by a bolt u. By actuating the switches m, n the downward movement of the rod i also serves to include the door contacts in the alarm circuit and to interrupt the ignition circuit G for the engine. The alarm horn or bell L is sounded when an armature w is oscillated .after being released from a catch lever x by the swing of a weight D on a spring C, this swing being caused by anyone shaking the vehicle after the downward movement of the rod i has released the weight D from a fork l<1>.

Title: Improvements in anti-icing means for the compressor of a gas turbine engine
IPC: F02C7/047
Filed: 1963-12-05
Abstract: 1,012,909. Gas turbine engines; axial-flow compressors. GENERAL ELECTRIC CO. Dec. 5, 1963 [Dec. 7, 1962], No. 48065/63. Headings FIC and F1G. The invention relates to the provision of antiicing means for the compressor of a gas turbine engine having rotatably mounted inlet guide vanes and possibly also stator vanes, each vane being formed with a cavity divided into two interconnected compartments at the leading and trailing edges thereof. A valve arrangement is provided in the rotatable supports for each vane to control the flow of a high temperature fluid into the vane compartment at the leading edge in accordance with the angular position of the vane. The gas turbine engine shown comprises an axial flow compressor 10 having a rotor 30 carrying rows of blades 29, and a stator casing 16, 25 carrying rotatably mounted inlet guide vanes 18 and rows of fixed stator vanes 28. The guide vanes 18 are mounted for rotational movement by means of spindles 19 at the radially outer ends of the vanes, the spindles engaging in bores 20 formed in bosses 21 integral with the stator casing 16. Each guide vane 18 is formed with an internal cavity which is divided into two compartments by means of a partition 50 the arrangement being such that heating fluid such as air tapped from a downstream stage of the compressor may flow through the compartment adjacent the leading edge of the guide vane then through the compartment adjacent the trailing edge discharging therefrom through outlets 51 into the air flowing into the compressor. Each spindle 19 has an internal bore which communicates by way of a port 42 with a port 41 in the wall of the boss 21, the port 41 being aligned with the internal passage of a duct 40. Air is tapped from the compressor through openings 36 into the manifold 35 and passes therefrom through a duct 37 to a second manifold 38 disposed at the upstream end of the casing, the air then passing to the ducts 40 and so into the guide vanes 18. The ports 41, 42 are so disposed that when the guide vanes are in the closed, low engine power position shown in Fig. 3 the ports 41, 42 are in alignment and so maximum flow of heating air is provided for. When the guide vanes are in the open, maximum engine power position shown in Fig. 4, the ports 41, 42 are out of alignment so that a lower amount of heating air, as a percentage of total air flow, is provided for. The first row of stator vanes may also be made angularly adjustable and provided with heating air flow passages and control means similarly to the inlet guide vanes 18. The air may alternatively be supplied to an annular manifold adjacent the radially inner ends of the inlet guide vanes passing therefrom through the hollow spindles which are formed similarly to the spindles described above.

Title: Improvements in and relating to the purification of combustion gases and apparatus therefor
IPC: B01D53/50
Filed: 1933-03-17
Abstract: <PICT:0416671/III/1> In the removal of oxides of sulphur from combustion gases by means of aqueous washing media, deposition of calcium sulphate dihydrate on the plant surfaces is reduced or inhibited by periodically removing the layer of washing medium which is in contact with such surfaces, as by flushing the surfaces with water.  The washing medium may be water, or preferably an aqueous suspension of calcium hydroxide or calcium carbonate, and the liquors may be used cyclically, in which case the water used for flushing comprises the whole or a part of the make-up water normally required. After contact with the combustion gases, the washing medium may be subjected to oxidation to convert calcium sulphite present into calcium sulphate, and the surfaces of the oxidizer may also be periodically flushed with water.  As shown, the gases pass up a gas washer 2 in countercurrent to washing liquor from a head tank 3, the liquor preferably being passed over rods, baffle plates, tubes or other tower packings.  The washing liquor is pumped through pipe 7 to tank 8 and thence fed to and through a head tank 10 into an oxidizer 11.  Oxidized liquor is mixed with calcium carbonate in vessel 14 and returned to storage tank 23 for re-use.  A part of the oxidized liquor is withdrawn to settling tank 26 and the clarified overflow passes to mixer 16 in which calcium carbonate for supply to mixer 14 is made into a slurry. For flushing purposes, the supply from tanks 23, 8 is cut off, and water supplied to the head tanks 3 and 10 from tanks 32, 33.  A number of washing units may be used with successive flushing of the surfaces in each to ensure smooth operation of the process. Specification 374,467 is referred to.
