Title: Improved light-sensitive photographic material and process of producing multicolour images employing the same
IPC: G03C7/28
Filed: 1936-07-16
Abstract: 483,463. Sensitive material for colour photography. GASPAR, 13. July 16, 1936, No. 7081/38. Convention date, July 16, 1935. Divided out of 483,366. Drawings to Specification. [Class 98 (ii)] Light-sensitive multilayer material comprises on a single support, a front layer which is colourless and blue-sensitive, a middle layer which is yellow and sensitive to red or green, and a rear layer which is sensitive to green or red and coloured with a colour which absorbs light for which the middle layer is sensitized. Images produced on such material will be in incorrect colours and are printed onto other material to produce a result in correct colours. For colouring the layers, Metanil Yellow, Diamine Fast Pink and Diamine Pure Blue may be used. Suitable sensitizers are thioflavin for green and ethylviolet for red. The dyestuffs may be precipitated in the coloured layers, e.g. as described in Specification 428,158. After exposure the dyes in the coloured layers are destroyed at the image or non-image parts. The image in the uppermost layer may be coloured by diffuse dyeing followed by destruction of the dye at the image or non-image parts, by chemical toning or dye-toning processes, or by tanning and mordanting processes followed by the application of dye. Where the dye destruction process is used, the dyestuff may be precipitated in the layer by means of diphenyl guanidine or lactic quinine or other precipitating agents as described in Specification 478,735. Specifications 421,534, 428,158, and 483,366 also are referred to.

Abstract: 1,220,932 Making corrugated tubes TEDDINGTON BELLOWS Ltd. 15 Feb., 1968 [15 Feb., 1967], No. 7195/67. Headings B3A and B3E. A method of forming convolutions in a tube 3 comprises arranging a single roller 1 to bear against one wall of the tube and a pair of rollers 6, 7 to bear against the other wall of the tube, rotating the tube, moving the axes of the roller 1 and the rollers 6, 7 towards each other and simultaneously moving two of the rollers along their axis or axes towards the third roller. The tube is held on a machine bed 21 by a clamp 22, and when it is secured a machine tool post 5 is displaced vertically until the roller 1 is at the level of the convolution to be formed. A machine tool post 16 is moved along a guide 17 until the rollers 6, 7 are opposite the roller 1 and a housing 12 is moved along guide pins 15 until the rollers 6, 7 bear against the tube. The tube 3 is rotated, thereby rotating the rollers 1, 6, 7 and as the tube is rotated the roller 1 is moved laterally towards the rollers 6, 7. At the same time the tool post 5 is lowered and the roller 6 is lowered at twice the speed of the post 5. After forming one convolution the rollers may be disengaged and re-set vertically to form further convolutions. In an alternative embodiment the two outer rollers are moved towards each other while the inner spindle is only moved laterally. Further the apparatus may be arranged with the spindles horizontal.

Title: Improvements in or relating to electric distant control apparatus
IPC: G05D3/16
Filed: 1939-04-03
Abstract: 577,849. Electric control systems. JAPOLSKY, N. April 3, 1939, No. 7219/38. [Class 40 (i)] [Also in Group XXXII] In a system wherein the transmitter 14 of a control system is controlled by a director, e.g., a handle 1, and "wrap up" mechanism comprising a flywheel 13 and springs 9, 10 interposed between the director and the transmitter to take account of rapid movements of the director which are outside the transmission limits of the transmitter and its receiver motor (not shown), a D.C. generator 18 driven by the director controls a motor 50 mechanically connected to the transmitter in such a manner that synchronising currents are generated to compensate undesirable jerky reactions on the director. As shown the director operates the transmitter through differential gearing 3, 4, 5 associated with the wrap-up mechanism 9, 10, 25, 26, 27 which is of the type described in Specification 505,511, and is such that the teeth of the wheels 25, 26 control the direction of operation of motor 50 in accordance with the direction of rotation of the director to assist the director in its control of the transmitter. The motor 50 also drives the wheel 27 to follow up the movements of the wheels 25, 26. The wheels 25, 26 control the motor 50 through the intermediary of a bridge connection of resistances 32-35, one or other of the arms 32, 33 of which is short-circuited by the wheels 25, 26 to produce P.D's of opposite polarity for driving the motor in opposite directions. The generator 18 is connected across the motor 50 and also a motor 44 which drives a flywheel 47 and the arrangement is such that normally when the operation of the director 1 is proceeding steadily within the transmission limits of the system, the back E.M.F. of the motor 44 offsets the voltage of the generator 18. If however rapid movement outside the limits is imparted to the director, a synchronising current is supplied to the motor 50. Similarly upon a sudden deceleration of the director, the flywheel 47 drives the motor 44 as. a generator and braking current is supplied to the motor 50. An inductance 22 is included in the output circuit of the generator 18 to delay the synchronising action. The wrap-up mechanism 9, 10 is operated by the planet wheels of the differential 3, 4, 5 and its function is to store algebraically rapid alterations in the movements of the director. Fig 3 shows one form of wrap-up mechanism. Springs 76, 78 are anchored to a rotable member 69 and to rotable and fixed discs 61, 66. The discs carry keys 65, 73 slidable in keyways and engaging screwthreading in flanges on the member 69. Movement of the shaft 58 in one or other direction winds one or other of the springs the arrangement be'ng such that when turned in one direction the spring 76 is wound and key 65 runs freely in its screw-threading whilst when turned in the other direction the key 65 locks the members 61, 69 and spring 78 is tensioned the spring 76 being rotated bodily.

Title: Improvements in or relating to the cooling of strips of material
IPC: B22D11/124
Filed: 1970-02-16
Abstract: 1,274,785. Continuous casting. MANNES. MANN A.G. 16 Feb., 1970 [17 Feb., 1969], No. 7271/70. Heading B3F. In a continuous casting process, the strand is passed through a roller arrangement which removes more heat from the longitudinal centre of the strand than from the longitudinal edges thereof. The rollers may have cooling passages therein, the distance between the passage and the roller periphery increasing in a direction away from the roller centre towards its edges. In another embodiment the roller has pits or grooves on its surface so arranged that the area of contact between the surface of the roller and the strand decreases towards the longitudinal edges of the strand. A decrease in the thermal conductivity of each roller from its centre towards its ends may be achieved by applying a firmly adhering layer of metal or an oxideceramic to the surface of the roller. Any liquid remaining on the strand after it has passed through a first cooling zone is removed e.g. by a roller, before the strand passes between the cooling rollers.
