Title: Improvements in or relating to cameras incorporating range finders
IPC: G03B13/20
Filed: 1935-05-23
Abstract: 457,137. Photographic cameras with telemeters. KODAK, Ltd., Kingsway, London.-(Assignees of Mihalyi, J. ; 333, State Street, Rochester, New York, U.S.A.) May 23, 1935, No. 15094. Convention date, May 31, 1934. [Classes 97 (i) and 98 (i)] In a folding camera, a rangefinder consisting of fixed reflecting means to bring two sets of rays at opposite ends of the base into the same field of view and a lens mounted between the ends of the base and moving parallel to the camera lens axis for effecting range adjustment, the movement is produced by a connection to the camera lens mount having two members which can separate when the camera is folded and are held in engagement by resilient means when the camera is open. In the form shown, incoming rays are reflected by prisms A, B to prisms C, D combined with a prism E for reflecting the rays to the eye through an eyepiece H. The prisms C, D are half the height of the prisms A, B so that an image is formed the lower half of which is produced by reflection in the prisms A, C and the upper by reflection in the prisms B, D. Lenses F, G are interposed in the paths of the rays from the prisms A, B to the prisms C, D, the lens G being fixed and the lens F being carried by a bracket J for lateral movement. The bracket J also carries a scale L which is viewed simultaneously with the images by reflection from the back surface of the prism D and indicates the distance of the object. The bracket J carries a projection abutting on a rod, the opposite end of which engages a rocking lever in the lens casing so that movement of the lens in focusing is transmitted to the lens F.

Abstract: 568,087. Elastic - fluid turbines. STEINSCHLAEGER, M. Sept. 15, 1943, No. 15149. [Class 110 (iii)] In a power plant comprising two or more turbines in series, gases produced in a combustion chamber 10 using fuel which is only partially burnt, are led to the first turbine 12 and then pass into a second combustion chamber 14 where further combustion takes place. The gases then drive a second turbine 17 and are led through a pipe 18 to a heat exchanger 5, finally flowing through a pipe 19 to an outside consumer. A compressor 1, preferably multi-stage, supplies air to a gas producer 6, by way of the heat-exchanger 5, and air to the combustion chambers 10, 14. The gas passes through an electric precipitator 8 for the removal of dust. Gases leaving the producer 6 may have air, steam or water added. The producer may be replaced by another type of gas generator.

Abstract: 1413061 Continuous hot dip galvanizing MANEELY-ILLINOIS Inc 30 March 1973 [28 April 1972] 15493/73 Heading C7F A continuous process of forming and galvanizing strip material e.g. steel, comprises feeding the strip 10 to a cleaning and degreasing plant 23, a tube forming and welding station 32, a pickle station 35 comprising three spray manifolds 40 where acid is applied countercurrent to the strip tube movement, an air wiper 41, a water rinse manifold 70 where the water is applied countercurrent to the tube movement, an air wiper 71, a furnace 75, 76 which heats the strip to 300-1300F in an inert atmosphere, a galvanizing pot 80, an air wiper and water quench and a shear 110. Pickling is effected at manifolds 40 by spraying hot aqueous 5-33% HCl through inclined holes in the inner tube of an assembly of two concentric tubes. The rinsing manifold 70 has a similar construction. The pickled and rinsed tube enters a sealed inert gas manifold 73 which feeds inert gas e.g. N2 into the two furnaces 75, 76 inductively heated by coils 77, 78. The molten Zn, which may contain Al is pumped and circulated to pot 80 from reservoir 90. Water quenching is effected by flowing water through a trough countercurrent to the movement of the tube sufficient to maintain the water at 85-140F at the entry of the strip. The Zn coating weight is controlled by an adjustable air wiper Fig.9 (not shown), which directs the air tangentially of the formed tubing and countercurrent to the tube movement. Instead of tubes, the strip may be formed into S bars and angles at station 32.

Title: Improvements in or relating to tiles, bricks, and other ceramic articles
IPC: B28B19/00
Filed: 1934-05-28
Abstract: Tiles, curbs, fireplaces, cornices, mouldings for shop fronts and other ceramic articles, either pre-moulded or cast in situ, are formed by embedding pieces of glass in one or more surface layers of relatively fine material such as cement backed by a layer of coarser material such as concrete.  The glass may be coloured and the surface layers coloured to harmonize or contrast with it.  In one process of moulding tiles, a layer of glass particles placed in the bottom of a mould is covered by a thin layer of semi-dry cement and water, followed by a main backing of dryer concrete which absorbs moisture from the cement layer during the subsequent pressing operation.  The glass face of the finished tile preferably is ground to produce a smooth finish.  The particles of glass may extend right through to the rear of the tile instead of forming a mere facing layer, and are preferably produced by breaking-up and partly grinding or crushing a large block of coloured glass.  The above process may be used to produce large sheets or slabs of material from which individual tiles are cut by a hollow plunger which also performs the compressing operation.  For casting in situ the surface to be treated is covered in turn with successive layers of concrete and cement and the particles of glass then pressed into the surface, for example, by rolling.  Specification 167,610, [Class 87 (ii)], is referred to.
