Title: A process for multi-color photography
IPC: G03C7/04

Abstract: 448,863. Colour photography. CLARKE, C. H., 24, Hermon Hill, Wanstead, London.- (Naamlooze Vennootschap Nederlandsch Laboratorium de Spaamestad ; Haarlem, Holland) Dec. 10, 1934, No. 35410. Drawings to Specification. [Class 98 (ii)] A process of multicolour photography is characterized by effecting in a layer consisting of various indelibly coloured small lightsensitive emulsion particles prepared from as many separately coloured and sensitized emulsions as there are colours, which particles act as light filters and mutually overlap, during or after exposure a hardening of the exposed or exposed and developed parts of the layer and removing the unexposed and unhardened parts, and, in the case of the use of silver halide emulsions, also removing the silver formed by the development. Three panchromatically sensitized emulsions are dyed blue with spiritsoluble aniline blue BB, red with spirit red B, and yellow with Sudan yellow GG and are atomized through nozzles and are collected on the support under benzene or in a vacuum. The emulsion particles may also be formed by grinding, cutting, spinning or shaking in liquids which do not dissolve the emulsion. A compensation filter may be formed by exposing a layer prepared according to the present invention to uniform light, hardening, washing out with hot water, and removing the silver with Farmer's reducer, and then coating with a further layer according to the invention. Alternatively, the layer according to the invention may be given a uniform pre-exposure. The silver in the exposed and developed layer may not be removed, but replaced by a white compound such as mercurous chloride or lead ferrocyanide. Alternatively, barium sulphate may be incorporated into the relief by alternately bathing in solutions of barium chloride and sulphuric acid. The layer may be formed on celluloid or paper.

Abstract: 1509162 Frequency-to-digital converter SIEMENS AG 26 Aug 1976 [27 Aug 1975] 35633/76 Heading H3H In a frequency-to-digital converter input pulses are counted in ADD to a predetermined value, providing a pulse from monostable IW which terminates counting of clock pulses from TG in counter ZZ. The contents of ZZ are transferred to shift register SR and the number of shifts taken until the highest hit position is occupied are counted in Z3. The higher value hits of SR content are passed through logarithmic converter FW and entered into store SP together with Z3 content to provide a logarithmic digital measure of the input frequency. The input pulses may be derived from the difference between two frequencies, and the output may be converted to analogue form in DAC. Means are described so that with a falling pulse rate the contents of the timing counter ZZ are shifted to register SR periodically, comprising a digital comparator VG comparing the result store input and output.

Abstract: 1,070,131. Cartridge-actuated tools. BURRA ENGINEERING CO. Ltd. Dec. 17, 1965 [Sept. 18, 1964; Sept. 17, 1965], Nos. 35971/64 and 39867/65. Heading B4C. A cartridge-actuated tool for driving fasteners such as pins or bolts into structures comprises a barrel 7 mounted in a housing 6 and an operating means 17, 18, 19 adapted, when the muzzle of tool is pressed against a surface, to advance a magazine 8 through the housing in a stepwise manner. The barrel 7 is slidable in the housing 6 and is formed with two arms 17, 18 between which the magazine slides, the housing being provided with apertures to permit such movement of the magazine. The magazine which may be of light alloy or synthetic plastics material is formed with two rows of cartridgechambers (65, 5) adapted to be brought alternately into alignment with one or other of a pair of bores 9 in the barrel. A firing pin 36 is mounted in a block (30, Fig. 2) loaded by springs 37, the pin having a pair of projections 36a. A hammer pin 41 is mounted in a block 38a, 38b, fixed in the housing, the pin being arranged to co-operate with a sear 52 carried by a leafspring 50. In operation, a loaded magazine is inserted into the tool until the end one of a row of teeth (73, Fig. 2) engages with a pawl 23 on the arm 18 of the barrel. Upon pressing the muzzle against a surface, the barrel moves thereby causing the pawl 23 to disengage the tooth and causing a second pawl 19 on the arm 17 of the barrel to engage the end one of a row of teeth (69) thereby indexing the magazine; the end cartridge-chamber 65 of the upper row is then brought into alignment with the upper bore 9 in the barrel. During the movement of the barrel the hammer pin 41 is cocked by the sear being moved rearwardly by the arms 17, 18. When a trigger 62 is depressed a lever 55 abuts the leaf-spring 51 thereby releasing the hammer pin so that it strikes the firing pin 36. A fastener is then driven from the magazine through the barrel, the exhaust gases passing out of the barrel via ports 10; in a modification the magazine may be formed with a single row or more than two rows of cartridge chambers. A splinter guard 12 is provided and may be formed with locating means for conduit clips or other parts adapted to be secured by the fasteners; the parts may be held in the guard by resilient or magnetic jaw or chucks.

[Also in Division H2] One or more parallel connected S.C.R.s 20, 30 are triggered by the regenerative gate current which is produced in a regenerative gate S.C.R. 10 after it has been triggered by a circuit 11, 14, 12. A regenerative (or inverse) gate S.C.R. is triggered by making its gate more negative than its cathode, and once triggered its gate is effectively connected to the anode, thereby providing a positive potential on its gate electrode, with a very short rise time. As shown, this potential is connected through a diode 16 to trigger standard S.C.R.s 20, 30. In an alternative embodiment (Fig. 2, not shown), all the S.C.R.s are of the regenerative gate type and the gate of the first one is connected to the others via a polarity changing transformer (18). Diodes (23, 33) block the initial triggering pulse from the further S.C.R.s and further diodes (22, 32) provide a path for their respective gate currents. The first S.C.R. 10 need not be in the main current path as shown. The application is to power switching to an unspecified load 3, one arrangement switching 20,000 amps at 1000 A/ micro second. The three terminal S.C.R. 10 shown is described in Specification 1,174,899 (Division H1); alternatively a four terminal version may be used as described in Specification 1,263,174.

Spray carburettors.-A piston 47 subjected to the engine suction is rigidly connected to an airvalve 46 and carries the fuel-valve 53, the valve end being held in a recess in the piston by a crosspin 55. The effect of the suction on the piston is variable by means of the valve 58. Rotation of the piston and air valve is prevented by a pin 51 and a slot 50 in one of the connecting-webs between the piston and valve. A cone 36 is movable by hand inside the air valve to vary the air admission. The cone has a number of projections 36', by means of which the air-valve and consequently the fuel-valve may be lifted at starting. The float feed valve 24 seats on the end of a slotted guide 26, which serves for the admission of the fuel to the float chamber.
