Title: Improvements in colour photography
IPC: G03C7/26
Filed: 1933-09-21
Abstract: 427,516. Colour photography. KODAK, Ltd., Kodak House, Kingsway, London.- (Assignees of Mannes, L. D., and Godowsky, L. ; Kodak Park, Rochester, New York, U.S.A.) Sept. 21, 1933, No. 18932/34. Convention date, Sept. 21, 1932. Divided out of 427,472. [Class 98 (ii)] Relates to the colour processing of multilayer photographic elements by colour development with a developer containing a colour former as described in Specification 376,838, and consists in a method of processing an element having a plurality of superimposed layers containing different colour sensation silver salt records, e.g. latent or bleached images-on the same side of a single support, which includes colour developing all the silver salt records to one colour, fixing if necessary, and then bleaching all but the bottom layer; the bleached layer is colour developed to a different colour. In an example, a film comprising a support carrying a thin layer of emulsion sensitized to red with naphthocyanol superimposed on a thin layer sensitized to green with erythrosin, after exposure in the manner described in Specification 427,472, is developed in a non-hardening developer, fixed, bleached in a dilute ferricyanide bath, exposed and re-developed in a minus-green colour developer comprising diethyl - p.phenylene - diamine with bromthioindoxyl, fixed if development is not carried to completion, and dried. The upper layer is selectively bleached by a chromic acid-bromide bath the action of which is arrested, before it affects the bottom layer, by time control and the use of a stop bath. A thin layer of clear gelatine is provided between the two emulsion layers to assist control. The stop bath consists of ammonia, with or without sulphite and methanol. The bleached upper layer is then exposed and developed with a minus-red colour developer comprising diethyl-p.phenylene - diamine with di- or tri-chlor-alphanaphthol after which the film is washed, the silver is removed with Farmer's reducer, and the film washed and dried. In an alternative method, the exposed film is directly colour-developed to the minus green. A master positive may be obtained from a negative film, thus processed, by contact printing and similar processing ; alternatively the film may be subjected to ordinary reversal treatment after exposure and then colour processed. Additive red plus green light is advantageous for copying. The colour sensitizing of the layers and their order may be changed ; and the intervening gelatine layer may contain a screening dye ; also the film may be processed to different colours, e.g. blue or blue-green and yellow or orange yellow. The application of the invention to the three-colour printing material set forth in Specifications 427,517 and 427,519 is also described. The invention may be applied to motion picture films or to still pictures on plates or films. Specifications 327,714, 333,902, [both in Class 2 (ii)], 356,308, [Group IV], 427,518 and 427,520 also are referred to.

Abstract: 953,267. Adjusting radio tuning controls; mounting radio receivers. MOTOROLA Inc. May 17, 1962 [May 31, 1961], No. 19092/62. Heading H3Q. A radio receiver mounted behind the dashboard of a vehicle includes a tuner control mechanism which comprises a rigid driven shaft having a fixed axis of rotation with respect to a curved slot formed in the receiver front plate, an adjustable bushing mounted in the slot, and a control shaft mounted in the bushing and having driving means thereon engaged with a rotatable member driving the rigid shaft and being driven by the driving means. The arrangement is such that the bushing is adjustable in the slot to adjust the control shaft circumferentially with respect to the axis of the driven shaft and maintain the driving means engaged with the rotatable member so that the control shaft may be secured at any desired position in the slot. The tuner control mechanism comprises a control shaft 55 rotatably mounted in a bushing 57 which includes a threaded portion projecting through a crescentshaped opening 17 in the receiver front plate 14. Attached to the inward end of shaft 55 is a drive disc 66, a portion of the periphery of which is captured by a pinch washer assembly 67 rotatably mounted on a stud 57a of the bushing 57. A second drive disc 68 affixed to one end of a shaft 40 is also held captured by the assembly 67. Thus manual rotation of the shaft 55 turns disc 66 causing rotation of the pinch washer assembly and driving of the disc 68. Disc 68 drives the shaft 40 and pinion 39 to rotate crown gear 38, thus causing rotation of shaft 37 and pinion 36 and gears 30. The tuner will then be driven through clutch discs 27, 28 and rotation of the shaft 22 which is connected to a carriage 20 through link mechanism 25, the carriage being operatively connected to tuning cores 19 and properly positioned for selected channels by the operation of sliding push-button rods 21. In order to adjust the position of the shaft 55 nut 65 is removed and bushing 61 loosened allowing disc 66 to be rotationally positioned with respect to assembly 67 which may be positioned with respect to disc 68. In this way , but limited by aperture 17, shaft 55 may be positioned anywhere in the aperture, Figs. 3a, 3b, 3c, and the distance between a volume control 43 and the tuner shaft 55 may be varied to coincide with the distance between apertures 11, 12 in the dashboard 10. In the embodiment of Figs. 4, 5 (not shown) the tuner mechanism is mounted parallel with the control shaft and the rigid tuner shaft is connected directly to the control shaft by means of a drive disc and a pinch washer assembly. In a further embodiment, Figs. 6, 7 (not shown), a tuner mechanism is mounted parallel to the front plate of the receiver and connected via an idler shaft and pinch washer assembly to a control shaft.

Abstract: 1279924 Cooling slabs SIEMAG SIEGENER MASCHINENBAU GmbH 22 April 1970 [26 April 1969] 19339/70 Heading B3M Hot rolled slabs 12 are progressively cooled by feeding them into a cooling wheel 1 which is half immersed in a tank of water, and then passing them over a conveyer 2 located within the tank. As a slab is fed by a feeder 13 into a generally radial slot in the cooling wheel, a further slab is moved by a feeder 15 from the wheel. The wheel is rotated in steps of between 45 and 90 degrees and may have an even number of slots as shown, or may have an odd number, the arrangement being that a slab is above the water level 6 when fed into the wheel, and below it when fed away from the wheel. To increase the efficiency of cooling, a pump 17 directs a jet of water on to a slab when in its first indexed position, the water being sucked from the base 18 of the tank. The water adjacent the wheel is heated, to, say, 80‹ C., while that adjacent the conveyer 2 is cooled, to say 30‹ C. The conveyer includes fixed longitudinal bars 21, and axially reciprocable bars 22, the bars 22 having pivoted dogs 23 which move the slabs towards the left of the tank as they reciprocate. Pivoted arms 26 lift the slabs from the tank and deposit them on a roller table 29.

Filed: 1967-04-27
Abstract: 1,185,494. Filter networks. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 27 April, 1967 [27 May, 1966], No. 19485/67. Heading H3U. Four terminal filter networks are provided, analogous to known " zero four terminal networks ", which may be designed to work as band pass, band stop, high pass or low pass filter, as desired. A known " zero four terminal network ", Fig. 1, operating solely as a band stop filter when on no load comprises a resistance-capacity circuit 1 having distributed constants and consisting of a metal surface conductor on which is a layer of a dielectric material over which there is a resistance coating. To provide a zero circuit action a resistancecapacity circuit 2 of predetermined dimensions is positioned in a shunt branch, this shunt branch ensuring that at a certain frequency the amplitude of the voltage transmitted by the four terminal network is zero. In a modification of the known network the circuit 2 forms a bridge connected in shunt with the circuit 1 (Fig. 2, not shown). The present invention uses circuits similar to those of Figs. 1, 2 but in which the circuit components are related by the following equation where Au = voltage transmission factor of the four terminal network. Ra = the selected terminating impedance. RL = resistance of the resistance-capacity circuit 1 with distributed constants, L being proportional to the length of the resistance layer and R = resistance per unit of length. Rn = the selected impedance of the circuit 2. γ = #jCR, i.e. the propagation coefficient in the case of a homogeneous conductor (C = distributed capacitance). The different types of filters are obtained by appropriate selection of the value and nature of the impedances Ra and Rn, these selections being given in the Specification.
