Title: Improvements in cameras for stereoscopic photography
Inventor: JEFFREE JOHN HENRY
IPC: G03B35/04
Filed: 1951-07-30
Abstract: 736,294. Stereoscopic photography. LENTIC (ENGLAND), Ltd. July 30, 1952 [July 30, 1951], No. 18002/51. Classes 98 (1) and 98 (2). In a method of taking stereoscopic photographs in which a spherical lens system is used to focus an image of the object upon a stereoscopic grid behind which is a photographic plate, the light is reflected at two mirrors located one on either side of the lens system which are moved so that those portions of the optical axis between the object and the first mirror and between the second mirror and the image are. displaced in the stereoscopic direction in opposite senses, thereby producing a stationary image on the plate of those portions of the object which are at a predetermined distance from the camera and stereoscopic images of those portions of the object located other than at the predetermined distance. As shown, a disc 10 rotatable about a horizontal axis 11 bears an eccentricallydisposed aperture 25 and a pair of parallel mirrors 12, 13 between which is an objective 16, mirror 13 being adjacent the aperture 25 and disposed to reflect light from mirror 12 through the aperture into a stationary chamber 26 containing a photographic plate 28 covered by a cylindrically lenticulated screen 27 with its lenticulations vertical, while mirror 12 is adjustable by freeing a screw 15 locking a slotted strap 14 for rotation about a horizontal axis perpendicular to the axis 11 to alter the centre of the stereoscopic field. The adjustment of the mirror 12 may be connected with the objective focusing. The objective is surrounded by a housing 17 fixed to the disc and apertured in register with the faces of the objective, said housing being disposed within a fixed shield 20 having vertically registering apertures, the housing and shield forming the camera shutter. To make an exposure, the disc is rotated by pulling downwards a cord 23 connected to it, thereby tensioning a return spring (not shown) and then uncovering the plate 28, whereupon on releasing the cord the disc rotates back to its rest position and so effects the exposure. In an alternative embodiment, the objective and mirrors are disposed in a hollow drum apertured opposite each mirror and rotatable about a vertical axis. In this arrangement a separate shutter is not provided, the shutter being formed by the aperture in the plate chamber and the adjacent drum aperture.

IPC: H01J29/39
Filed: 1928-06-01
Abstract: 318,299. Pollak, J. E., (Associated Telephone & Telegraph Co.). June 1, 1928. Divided on 318,565. Vacuum tubes.-A photo-electric, cell for use in television systems or the like consists of an insulating slab having on or adjacent to one face a coating of material which becomes conductive under the influence of cathode ravs and on or adjacent to the other face a material whose conductivity varies with the intensity of light incident thereon, the two faces being connected by a large number of individual conductors. A slab of insulating material 36, Fig. 1, has conductors 37 extending through the slab from face to face and conductors 39, 38 extending from each face part way into the slab, which conductors form two grids connected in a battery circuit as shown. One face of the slab is coated with material 41 responsive to cathode rays such as selenium or potassium hydride, the other face being coated with light-sensitive material 40 such as selenium. The image is formed on this coating, which is not thicker than the depth of effective penetration by light, while the other face is scanned by cathode rays which thus activate the coating and complete the battery circuit allowing currents to flow dependent on the resistance of the elemental area of selenium on the other face of the slab. The slab may be of glass, the conductors being fine wires traversing the thickness of the slab, and the grids may consist of fine mesh screens 43, 44, Fig. 5, adjacent to the faces, or one grid 38, Fig. 6, may be embedded in the slab and the other grid 43 adjacent. The slab may be constructed by winding a number of glass strips with wire, Fig. 8, mounting them together with unwound plates separating the wound plates, Fig. 9, the whole being fused, the portions of the face containing wire not normal to the surface being ground off. Or a coil of insulating wire may be treated with varnish, and when hard, cut as shown by the dotted lines in Fig. 7, thus obtaining eight slabs. Specification 318,565 is referred to.

Title: Improvements in or relating to the manufacture of unsplinterable glass
IPC: C04B28/24
Filed: 1928-06-25
Abstract: 306,351. Robertson, J. H. June 25, 1928. Compound transparent sheets.-To secure firm adhesion between the glass and celluloid sheets forming non-splintering transparencies, the glass is first coated with a cement consisting of a gelatinous silicate in a hot solution of gelatine with or without potassium chrome alum. or of albumen, or of casein. The coated face is dried and a celluloid sheet of about 0.005 inch thickness, softened with an acid such as propionic acid is secured thereto, or alternatively, a solution of 1 gram celluloid, 30 ccs. amylacetate, and 4 cos. propionic acid may be applied thereto. Two sheets formed by this process are then joined to a sheet of celluloid by immersing them in a bath of propyl alcohol and gently pressing them together. If treated with potassium chrome alum, the gelatine solution is prepared by adding gradually 100 parts of a boiling solution of 0.2.5 per cent chrome alum to 100 parts of a boiling solution of 4 per cent agar-agar or gelatine and maintaining the resultant solution at 95‹ C. for half an hour, then filtering through cotton wool and mixing hot with the gelatinous silicate solution. Casein when used is preferably dissolved in strong sodium silicate solution which is then diluted and filtered and applied to the glass cold. When dry, this coating may be treated with a solution of casein in ammonia to provide a surface which will amalgamate with the celluloid layer. Drawn glass is preferably used and it is cleaned with nitric acid and distilled water. The edges of the finished sheets are sealed with casein, resinous bodies, silicates, gutta percha. &c., or with the product obtained by precipitating meta styrene with acetone in benzene solution and treating the precipitate with tri-cresyl phosphate.

Abstract: 689,799. Automatic voltage control circuits for X-ray tube supplies. GENERAL RADIOLOGICAL, Ltd., and QUITTNER, V. July 18, 1951 [July 22, 1950], No. 18362/50. Class 38 (iv). The voltage across an X-ray tube 1 is maintained at a predetermined value by a switching valve 2 in series with the tube and biased by the rectified output of an H.F. oscillator unit 10 controlled by the difference in voltage between a potential divider 4, 5 and a reference potentiometer 8 adjustable to switch the tube on and off and to vary the setting at which the voltage is maintained. The control circuit is insulated from the switch valve by an H.F. transformer 12. As shown, one switching valve is used on each side of the X-ray tube, as described in Specification 689,798, with identical control circuits, a valve 114 being used to reverse the polarity sense of the control voltage in the second circuit, so that both switch valves act in the same sense. In an alternative arrangement the switch valve is normally biased to cut-off, and an auxiliary amplifying valve, also biased to cutoff in the absence of a control signal, allows a positive bias to oppose the switch valve bias as the control voltage is applied, Fig. 2 (not shown), to give a more sensitive control.

Title: Improvements in or relating to color photography and sensitized material therefor
IPC: G03C7/04
Filed: 1924-08-02
Abstract: 238,688. Thornton, J. E. Aug. 2, 1924. Colour photography.-Sensitized film material for the production more particularly of tricolour kinematograph films, which are built up by cementing together two component films as described for example in Specification 224,569, is provided with a two-colour mosaic screen over half its area, and a single-colour full-tone screen over the remaining half. The colour record negatives are made on such material preferably by simultaneous exposure through a single lens and an optical dividing system producing two side-by-side images. From these negatives, or from printing-plates produced therefrom in known manner, the colour-record positives are printed by projection through one or two lenses upon similar but thinner material, and the records are cemented together in register either face to face, or back to back, or face to back. The material is preferably of double picture width with the screens arranged side by side; but two strips of single-width material, each carrying one of the colour screens, may be used. In the case of kinematograph negative films, single-width material having an alternating sequence of the colour screens may be used, and this may be exposed to produce pairs of images simultaneously either as described above or by using two lenses. Alternatively, with this material. single images may be produced in succession by using only one lens. Negatives having the images in alternating sequence may either be employed themselves to print the positive records, or may be used to produce printing- plates each containing one of the component picture-series in direct sequence, from which the positives are printed. The negative material is produced by coating on a celluloid or other transparent support an adhesive substratum, a laver of colloid on which the colour screens are formed, a second adhesive subtratum, and a layer of rapid panchromatic emulsion. The first substratum layer and the colour-screen layer may be combined as one layer. The two-colour screen is produced as described in Specification 224,571. The positive material is similarly produced, but upon a support of half the thickness, which may be temporarily reinforced with paper as described in Specification 224,571, and the sensitive layer may be rapid or slow. The films are registered during taking, printing, &c. preferably by the one-hole method described in Specification 233,991, and carry marks to assist in identifying the various sections. When double-width positive material is used, it is slit longitudinally into two strips before cementing. If the component positive films are to be cemented face to face, the method described in Specification 232,202 is preferably used. A - solution of the material forming the support is used when the films are to be cemented back to back. The invention may also be applied to the production of ordinary photographs on glass, film or thin tissue supports. Specification 112,769 also is referred to.

Abstract: 582,198. Pulse modulation; multiplex systems. STANDARD TELEPHONES & CABLES, Ltd., CHATTERJEA, P. K., and HOUGHTON, L. W. April 7, 1943, No. 18640/44. Divided out of 582,177. [Classes 39 (i) and 40 (v)] In a multi-channel pulse signalling system, interlaced time-modulated pulses are produced by means of cathode-ray tubes with shaped targets. For a four-channel system, the target may comprise four curved metal bars a.... d radiating from a central hub e. The ray is given a circular movement along the path f by pairs of plates or coils energized in quadrature. In addition, the ray is given a radial deflection by the four separate modulating signals applied between the central plate 1 and the four circumferential plates 2 ... 5,. so that each signal deflects the ray as it is passing the corresponding target. The four trains of timemodulated pulses are taken off across the resistance R. In a modified arrangement, a separate cathode-ray tube is used for each channel, the target in each being a metal bar set at an angle to the scanning co-ordinates which are provided respectively by the signal and by a saw-tooth or other wave of pulse repetition frequency as in Specification 523,575. The saw-tooth or other wave is suitably phased for each channel, and the pulses are combined into a single train before transmission. Slotted targets backed by collector plates may be used instead of the metal bars.
