Title: Process for the production of coloured photographic pictures
IPC: G03C7/25
Filed: 1934-08-08
Abstract: 447,032. Photographic imbibition printing processes ; colour photography. 1. G. FARBENINDUSTRIE AKT.-GES., Frankforton-Main, Germany. Aug. 8, 1934, No. 22950. Void [Abridged as open to inspection under Sect. 91 of the Acts, Feb. 9, 1935]. [Class 98 (ii)] In an imbibition process, the printing-surfaces are produced by exposing to light a thin gelatino-silver emulsion layer, developing it, and treating it with an agent such as hydrogen peroxide, or ammonium persulphate, which removes the gelatin containing the silver image and leaves the remaining gelatin relief absorbent. The emulsion may contain a finely-dispersed, "photographically-indifferent," coloured pigment in order to improve gradation. The dye to be imprinted is applied to the relief in aqueous alcoholic or aqueous-acetone solution, and the prints may be made on gelatincoated paper, which should contain a mordant in the case of basic dyestuffs. Printing may alternatively be performed with a substance which produces a colouring-matter only in co-operation with another substance, which may be present in the print surface before printing or may be applied subsequently. Pairs of substances which may be so used are diazo bodies and their coupling-components, silver nitrate and sodium sulphide, or indigosol and hydrogen peroxide. In one example, a blue-black print is produced in a gelatin layer by using the acid dyestuff Brilliant Black B. In another example, tricolour components are printed in succession with basic dyestuffs in a gelatin layer containing a copper-silver thiocyanate mordant, the dyes used being Para-fuchsine for the red, Auramine G for the yellow, and Turkish Blue G for the blue, and registration being effected by pins.

Title: Improvements in or relating to particle-counting systems
Inventor: GALPIN HAROLD HENRY ALBERT
IPC: G06M11/02
Filed: 1954-08-12
Abstract: 779,160. Photo-electric particle counters. CINEMA-TELEVISION, Ltd. Aug. 11, 1955 [Aug. 12, 1954], No. 23429/54. Class 40 (3). In an apparatus for counting particles in which an area comprising the particles is scanned, for example by a travelling light spot, to derive signals corresponding to the presence of an object in order to produce pulses which have only two possible valves the scanning spot is traversed in at least one direction in a succession of substantially instantaneous transitions from one position to an adjacent position separated by pulses of finite duration at each of the positions. As shown, a transparency B comprising the objects to be counted is positioned in front of a photo-cell 5 which produces impulses when the light beam is intercepted by such an object. The output pulses are amplified at 6, recorded on a rotating magnetic track 8 by a head 7 and applied to an anticoincidence circuit 10. Signals previously recorded on the track are read in known manner by the same head and the anti-coincidence circuit, which may be as described in Specification 778,288, delivers a pulse to a counter 11 only when the scanning spot encounters a transparencing for the first time. Also recorded on the magnetic drum are 200 sinusoidal signals in a track 13 which signals are read by head 12 and used to control the " line " defiection of the scanning spot through a scanning generator 18 and the intensity of the spot through a device 14. Scanning generator 15 is such that each negative-going peak of the applied sinusoidal signal produces a movement of the scanning spot from one position to an adjacent position while during positive excursion of the signal the spot is stationary. Thus the waveform of generator 15 is a " staircase ". Device 14 causes the spot to appear only during the positive going peaks of the sinusoidal signal. A signal produced in generator 15 during the fly-back at the end of each line is applied to a dividing circuit 16 which produces a signal having the frame frequency and sychrons a scanning generator 17 to generate a frame saw-tooth. Alternatively a third head 18 may receive a signal 19 of line frequency recorded on drum 8 and fed to the divider 16. Specification 778,289 also is referred to.

[Class 56] A method of tempering glass comprises the step of supporting the glass during heating by a device which engages and supports it without deformation, and in observing the temperature or condition of each piece of glass and controlling the heating of the glass accordingly. The temperature or condition may be observed or determined by one of several changes which occur in 'the physical properties of glass with changes of temperature, such as the thermal expansion or electric conductivity, or the softening of the glass. Specification 431,095 is referred to. A sheet of glass may be supported by a frame 15 suspended from a carriage 14 by which it is conveyed through the heating and cooling devices. The sides and base of the frame are provided with U-shaped clips 17 which embrace the edges of the sheet. The device for observing the temperature of the sheet comprises a narrow strip of glass 18, cut from the same glass as the sheet, clamped at one end in a bracket 19 attached to the carriage 14. The bracket 19 also carries an arm 22 provided with an adjustable stop 23. During the heating process, the strip 18 commences to bend, and the position of the stop 23 is so adjusted that it is engaged by the bending strip 18 as soon as the glass sheet is heated to the proper degree for tempering. The strip 18 may also be arranged to actuate a lever which closes an electric circuit to give a visual or audible signal when the sheet is sufficiently heated. The sheet or sheets may be supported by the devices described in Specifications 506,723 and 506,787, and the method may be carried out in the manner described in Specifications 449,602, 449,864, 473,065, and 473,066.
