Abstract: 939,704. Rotary engines and pumps. CURTISS-WRIGHT CORPORATION. May 1, 1961 [May 2, 1960], No. 15683/61. Class 110 (2). A rotary internal combustion engine, compressor or pump has an aluminium alloy rotor 10 with a plurality of apex portions 38 engaging the inner surface of a housing 12, and driving (or being driven by) a shaft 34 by a steel eccentric 36 integral with the shaft. Fig. 3, in which the components are drawn partly out of engagement for clarity, shows an outer steel sleeve 50, shrunk into the rotor 10 and an inner steel sleeve 52 shrunk into the outer rotor, and bearing on the eccentric 36. The shrink-fit of sleeves 50 and 52 is such that the outer sleeve 50 will be fixed to the rotor at all temperatures, whereas the inner sleeve 52 which expands less, becomes free below the operating temperature, and acts as a floating bearing. The inner sleeve however is provided with radial splines 56 which engage splines 60 on the rotor. The inner ring is also provided with a gear ring 54 which engages a gear ring 58 fixed to the casing. In the embodiment shown the gear ratio between 54 and 58 is 3 : 2 ; these gears are provided to relieve the loads on the apices of the rotor. On the end of the inner sleeve 52 remote from the gear ring 54 is secured a nut 62 having a flexible flange 64 which bears against the outer ring and prevents lubricating oil escaping from between the two sleeves 50, 52.

Filed: 1924-07-02
Abstract: 233,647. Johanknegt, J. C. May 10, 1924, [Convention date]. Ships with optical-projection apparatus.-A boat for advertising has mounted in a telescopic tower 4 an optical-projection apparatus which throws images on a screen 2. The screen 2 comprises a sheet of ground glass or a glass mirror or a canvas sheet, and is protected from the weather by a transparent glass sheet or by a coating of transparent material such as paraffin. The screen is adapted to be lowered either by causing it to descend vertically into the boat or by pivoting its supports 10 at 9, or by a combination of these movements. The pivoting motion is effected through gearing 11, 12 and a worm 13 operated by a handle 14, locking means being provided for the worm shaft. An advertising panel 23 is pivoted between the supports 10, the pivot 24 being for the purpose of turning the advertising face of the panel downwards for protection when the screen is lowered, in which case the panel shaft may be connected by a two to one chain gear with the pivots 9, or for rotating the panel during display so that each face, bearing advertisements, is successively presented tn the front. A time indicator 22 is arranged above the screen. The elements 29, 30, 31 comprising the tower 4 bear on one another through friction rollers and may be extended by winches or cranes or by lazy-tong levers which may be displaced by helicoidal screws having an autornatic brake. Alternatively the projector cabin may be suspended from masts or be arranged in uprights raised on hinges by winches or toothed sectors. Windows, doors, a roof, and climbing ladders are provided for the tower 4. The projection apparatus may be mounted at the top of the tower or at the base and be combined with a periscope. The screen 2 and tower 4 may be stayed, when erected, by cables. Water ballast tanks 5, 6 controlled by a pump 8 are fitted in the hull 1. Advertisements may be carried on the screen supports at 21, on the sides of the tower 4, and on the living cabins 3 at 27, 28, the panels 28 being hinged to close down on the panels 27.

Title: Improvements in or relating to optical projection systems
Inventor: DAVIS JOHN KING
IPC: G02B17/08
Filed: 1954-05-28
Abstract: 759,217. Optical systems. AMERICAN OPTICAL CO. May 28, 1954, No. 15908/54. Class 97 (1). A projection system comprises a plane mirror and a concave mirror facing one another, each mirror having a central aperture whereby light from the object passing through the aperture in one mirror is reflected by the second mirror back to the first mirror which in turn reflects the light through the aperture in the second mirror to form an image, an opaque baffle being located between the mirrors to intercept the major portion of the light passing directly through the two apertures. As shown, light from an object 1 such as a cathode-ray tube, passes through a central aperture 8 in a plane mirror 4 to reach a concave spherical mirror 3 from which it is reflected to the mirror 4 and thence directed through the central aperture 6 of the mirror 3 to form an image on a screen 7. A Schmidt plate 10 is provided in the aperture 6 to correct spherical aberration and an opaque baffle 9 prevents direct light from the object 1 reaching the screen 7. If desired, the baffle 9 may be dimensioned so as to allow some direct light to reach the screen to produce even illumination. A further diaphragm 12 may be provided. In a modification, the mirror 3 is replaced by a rear-surface reflecting lensmirror, correction being effected by lenses placed adjacent the mirror 3 between it and the screen 7. Alternatively the plate 10 may be replaced by a concentric meniscus lens convex to the mirror 4, or by a similar meniscus, convex to the screen 7 and located between the latter and the mirror 3.

Abstract: 1,100,796. Gas analysis, electrically and photo-electrically. L'AIR LIQUIDE SOC ANON POUR l'ETUDE ET L'EXPLOITATION DES PROCEDES GEORGES CLAUDE. April 12, 1966 [April 8, 1965], No.16032/66. Headings G1A and G1N. Gas analyzing apparatus comprises an ionization cell CD, electrodes AB outside the cell and connected across a transformer secondary winding S, the primary winding together with capacitors C, C 2  forming an oscillator circuit energized by a high frequency generator GHF. As a measure of variation in the impedance between the two electrodes when a gas to be analyzed is introduced to the cell together with a helium carrier, there is obtained a difference voltage, which is the difference between a rectified predetermined percentage of the secondary voltage appearing across R 1  and a reference voltage across R 2 , which is a rectified percentage of the primary voltage (e.g. 100% in this case). The difference voltage is applied to a recorder EP. Where the carrier is argon, the intensity of luminosity is utilized and is sensed by photo-resistors PC to vary the voltage across R 3  which is switched into circuit instead of R 2 . The voltage across R 1  is then used as a reference - and a capacitor C 1  is switched across the electrodes AB in order to reduce the effect of the voltage variation between electrodes upon the impedance of the oscillatory circuit. Optical filtering means may be selectively interposed between the cell and the photo-resistors. When it is desired to have a more detailed chromatographic analysis, there may be provided several banks of photo-resistors.

Title: Improvements in or relating to slicing machines
IPC: B26D7/06
Filed: 1933-06-06
Abstract: 419,615. Cutting and slicing bread &c. STEVENS, A. H., 5, Quality Court, Chancery Lane, London.-(Ward Baking Co. ; 367, Southern Boulevard, New York, U.S.A.) June 6, 1933, No. 16250. [Class 5 (i).] A machine for slicing bread &c. has a helical knife 11 with a spiral cutting- edge, and the loaves are fed positively by pushers 23 between guides 19, 20, fixed and adjustable respectively, which are necessarily gapped for the passage of the knife. The loaf is supported laterally at the gap of the guide 19 by a skeleton drum comprising a positively rotated disc 45 with upstanding fingers 46 spaced peripherally of the disc according to the pitch of the helix of the knife. The bread is pressed by the cutting action against the guide 19 so that a supporting drum is preferably provided in association with the guide 19 only, although a similar drum could be provided for the guide 20. The knife comprises a metal sheet with a central aperture, and is sprung into helical form by bolting it to a backing-member 38 on the shaft 12. The cutting edge of the knife is serrated and the serrations are aligned with flutings or grooves 41, on one side of the knife. The lengths of the flutings increase as the cutting radius increases. If the machine is used in conjunction with a wrapping machine, the pushers 23 continue to advance the loaves until they are properly positioned to be transferred thereto. The pushers are rendered inoperative before the chain 24 carrying the pushers passes around the end sprocket 26, and the point at which the pushers are rendered inoperative is variable. This is effected by mounting an arm 34 on each pintle 341 carrying a pusher, the arm 34 having a roller or rounded end to bear on an adjustable guide 35. When the arm 34 leaves the shoulder 351, the pusher is free to swing backwards into the inoperative position. The position of the shoulder 351 is varied by adjusting the guide 35. The loaves may be advanced to the knife without intermediate gaps, in which case the loaves are advanced by gripping-means.

The secondary support may contain the alkaline earth metal oxide in an amount to form a stoichiometric compound, e.g. melilite or gehlenite. The support may be formed by (i) applying a suspension of preformed secondary support to the primary support surface; (ii) applying a solution or suspension of secondary support precursors to the primary support surface and then heat treating to effect reaction and form the secondary support in situ; or (iii) selecting a primary support comprising one or more of the oxides to be combined in the secondary support, applying the other oxides or their precursors thereto and effecting reaction to form the secondary support at the surface of the primary support. The primary support may be alumina, silica, titania, magnesia, hafnia, thoria, chromia, aluminosilicates such as cordierite or zircon-mullite, alphaalumina bonded with bentonite, calcined kaolin/cement mixtures, petalite, silicon nitride or oxynitride or glass. It may be in the form of granules, fibres, multi-tubular matrices or coatings on metallic substrates such as vessel walls or meshes. The secondary support may further comprise zirconia or rare earth oxides. The support may have a catalyst applied thereto for I.C. engine exhaust gas treatment and may form part of a catalyst composition comprising 0.001-5% wt of a platinum group metal or 2-50% wt of metallic nickel and/or cobalt (calculated as monoxide) or their oxides, optionally further containing 2-10% wt copper (calculated as CuO and based on Ni/Co monoxide) or oxides of manganese or chromium or a platinum group metal. The exhaust gas treatment may be effected in two stages-reductive followed by oxidative and a preoxidation catalyst may be arranged upstream of the reductive zone. The formation of an uncalcined catalyst may be completed in situ by initially adjusting the I.C. engine to give an exhaust containing 3-8% vol of CO and adding air to oxidise this and produce a temperature above 800C for calcination of the catalyst. When this is complete, the engine may be re-adjusted to normal running conditions.

Class 124 A combined air and water control valve for a rock drill comprises a water inlet in the back head of the drill, a first passage leading from the water inlet to a water valve chamber, a check valve in one end of a counterbore the other end of which is connected by a second passage to the water valve chamber, the  '.counterbore also being connected to a water delivery tube, a third passage leading from the throttle valve to the counterbore, the check valve normally preventing water from entering the third passage, a cam on the throttle valve opening the water valve in one position and in another position closing the water valve  and admitting air to flow through the delivery tube. As shown, Fig. 4, air is admitted from a throttle valve 75 to the valve gear of the drill through a port 81 and passage 82. A threaded opening 85 in the throttle valve housing is connected to a water supply and has a bore 86 leading to a water valve chamber 87, Fig. 5, having a valve 91 operated by a cam 88 on the throttle valve 75. A passage 95 leads from the valve 91 to a counter bore 97 in the back head from which water may pass through radial bores 100 in the enlarged head of a water delivery tube 63. A ball valve 104 prevents water flowing into a passage 109 leading to the throttle valve. On moving the throttle valve into the "ON" position water is admitted to the delivery tube by way of the moving the throttle valve to the "OFF" valve 91 and air to the valve gear. On position the flow of water is stopped, air is cut off to the valve gear, and is admitted to the bore 109 through the port 110. The air pressure overcomes the resistance of a spring 105 and moves the ball 104 off its seat to allow the air to flow through the delivery tube 63 and prevent sludge from entering the bit, particularly when the bit remains in an overhead hole. A feed leg may be fitted to the back head and have pressure air supplied to it through a bore 84. A detent 113 may co-operate with holes 114 in the throttle valve to maintain the valve in the required position. The drill steel may be rotated by the usual ratchet gear.
