Title: Improvements in or relating to amusement apparatus
IPC: A63G7/00
Filed: 1923-08-11
Abstract: 215,238. Jackson, W. J. Mellersh-, (Maynes Corporation). Aug. 11, 1923. Roundabouts.-A tunnel encloses the cars of a roundabout and moves relatively to the cars, central means being provided to extend and collapse the tunnel. In Figs. 1 and 3, the invention is shown applied to a roundabout in which the cars 2 are propelled along an annular track 1 by means of an electric motor mounted on a car, or by similar means. The collapsable tunnel 3 is carried by extensible arms 15 carrying rollers 21 which run on a track 22 supported within or without the track 1 by pillars 23. The inner ends of the arms 15 are pivotally secured to a turntable 5 connected by a shaft 7 with a lower turntable 6, which is rotated by means of a motor 12. Pinions 24 are secured to the inner, downwardlyprojecting ends of the two arms 15 which support the ends of the tunnel 3 and mesh with pinions 29 and 31, 32 respectively. The pinions 29, 32 mesh with a gear 25 rotatably mounted on the shaft 7, a motor 26 driving the gear 25. The tunnel 3 is formed of heavy fabric in the manner of bellows, so that a rotation of the gear 25 causes the two end arms 15 to move towards each other to collapse the tunnel so that passengers may enter the cars 2, or away from each other to extend the tunnel. In a modification, a further turntable may be provided to drive the cars 2 by means of radial arms. The tracks 1 and 22 may be of undulating form. The tunnel and cars may be provided with pairs of rollers 82 running on the faces of diagonallyarranged rails 83. The cars may be connected together by rods 85, the spherical ends 86 of which are held between blocks 87. In the form of apparatus shown in Fig. 9, the cars 56 are carried by arms 55 pivotally mounted on a rotating platform 54 carried by a truck 44. Inwardly-extending arms 69 of the arms 55 engage a cam-surface 72 inside a stationary member 146 so that the cars 56 follow an undulating course on rotation. Links 74 and pins 75 limit the rocking movement of the cars 56. The tunnel 49 is carried by arms 48 pivotally mounted on a rotatable member 47 driven from the worm 52 through the shaft 46. Rollers 62 on the arms 48 engage an external cam-surface on the member 146 to cause the tunnel to follow an undulating course and links 64 prevent rocking movement of the tunnel. The side walls 76 of the tunnel 49 may be raised by means of cables 77 to afford an entrance to the cars 56.

Title: Improvements in or relating to electron discharge devices for use in television and like systems
IPC: H01J31/42
Filed: 1937-07-26
Abstract: 499,662. Discharge apparatus. FERNSEH AKT.-GES. July 26, 1937, No. 20629. Convention date, July 28, 1936. [Class 39 (i)] In an image dissector the scanning anode contains an apertured diaphragm 6, Fig. 1, maintained at a potential slightly negative (of the order of 20 volts) with respect to the photo-electric cathode 8. This diaphragm, together with larger apertures in the outer anode 4 and collector 7 which are at positive potentials of the order of 1000 volts, forms an electron lens the effective aperture of which may be varied by varying the negative potential of the diaphragm 6. The size of the scanning spot may thus be adapted for different numbers of scanning lines; or the diaphragm may be heavily biassed to avoid collection during flyback periods. In a modification, Fig. 3, the position of the scanning aperture may be varied electrically for intercalated scanning by splitting the diaphragm 6 into two portions 21, 22 enclosing an aperture and biassed at slightly different negative potentials. By interchanging these potentials the effective aperture shown by the dotted line - 2 in the Figure, may be shifted through the width of a scanning line. Specification 463,828 is referred to.

Title: Improvements in or relating to tropane derivatives
Filed: 1958-06-30
Abstract: Derivatives of 6:7b -epoxy-3a -hydroxytropane are prepared by the oxidation of the corresponding 6-tropen-3a -ol derivatives by means of 30-100% hydrogen peroxide together with one or more organic acids convertible to peracids.  Preferred starting materials are 6-tropen-3a -ol esters and their quaternary ammonium salts.  In examples: (1) 3a -acetoxy-6-tropene is oxidized with 90% H2O2 and formic acid to acetylscopine, characterized as its picrate: (2) 3a -acetoxy-6-tropene is hydrolysed with 2N HCl, the resulting tropenol hydrochloride is esterified with acetyltropyl chloride, and the ester is oxidized as in (1) to acetylscopolamine which is hydrolysed to scopolamine (or hyoscine if optically active acetyltropyl chloride is used); (3) tropenol hydrochloride is quaternized with n-butyl bromide and the product esterified, oxidized and hydrolysed as in (2) to yield finally(-)-scopolamine n-butobromide.  Reference has been directed by the Comptroller to Specification 708,370.

Title: Improvements in cameras for colour photography
IPC: G03B33/00
Filed: 1944-10-27
Abstract: 589,661. Photographic and kinematographic colour cameras. BARNES, H. 'Oct. 27, 1944, No. 20917. [Classes 97'(i) and 98 (ii)] In a photographic or kinematographic colour camera, a carrier having mounted thereon one or more sets of beam splitting means consisting of at least two angularly displaced reflecting members with or without an intervening aperture is moved across the image forming beam whereby images are simultaneously produced, at least one set of beam-splitting means being always within the image-forming beam during the passage of the carrier. As shown, the carrier D situated between the camera objective E and its focal plane, carries mirrors A and B separated by an aperture C, and is adapted to slide to produce images successively on the plate A<1>, the plate C<1> and the plate B<1>. Colour filters A<4>, B' and C<4> may be arranged in front of each plate. The carrier may be spring- loaded and released synchronously by the shutter mechanism, or may be operated independently. In modification, either or both of the mirrors A, B may be subdivided into strips with an aperture C arranged between pairs of strips. In this case a small sliding movement of the carrier is necessary. In a further modification, three reflectors A, B and C are provided to reflect the rays on to three sections A <1>, B<1> and C <1> of a film F, as shown in Fig. 3. A single piece of glass or other material ground or moulded to the required angles and silvered, with clear strips between the silvered portions, may be used. In colour kinematography, the sliding carrier may be geared to the camera mechanism so that a single traverse of the carrier across each frame is accomplished while the shutter is open. Three or more reflectors may be used in four- or more colour photography. According to the Provisional Specification, only a single reflector .may be used in two-colour photography.

Patent GB-623625-A (GB)
Title: Materials for use as bearings and like rubbing contact surfaces
IPC: B26D5/22
Filed: 1946-04-26
Abstract: A material which may be used for the production of bearings and mechanised seals, comprises silver or a silver base alloy bonded but not alloyed with one or more of the stable carbides, nitrides, or silicides of metallic elements of groups 3, 4, 5 and 6 of the Periodic Table.  The silver base alloy may contain up to 20 per cent by volume of tin, indium or thallium.  In cases in which the components do not form alloys even at high temperatures the powdered substances may be mixed and then heated to a temperature between the melting points of the components.  When the components may form alloys, the high melting component is powdered and then sintered to form a porous mass which is dipped into the molten low melting component, such process being preferably carried out in a reducing or neutral atmosphere.  The p  surface of the product may be modified, e.g. by means of alkalis which tend to remove tungsten carbide, or by acid which tends to remove silver or silver alloy.
