Filed: 1927-09-22
Abstract: 302,983. Hoe & Co., Ltd., R., and Bennison, W. E. Sept. 22, 1927. Divided on 302,966. Rotary intaglio machines; gripper mechanism. - A rotary intaglio machine of the kind described in Specification 302,966 is constructed with means for automatically retarding the grippers relatively to the impression cylinder at the commencement of the printing operation, so that the sheets are paid out solely by the friction of the cylinders, thus preventing tearing of the sheets. The grippers are carried by discs 15 freely mounted on the cylinder 2 and driven by epicyclic gearing. The impression cylinder 2 is geared directly to a shaft 31 driven by gearing from a motor, and this shaft 31 is geared to a gear 19 freely mounted on a shaft 18 with fixed gear wheels 17, 17<a> geared to the discs 15. Motion is transmitted from the gear 19 to gear 17 by means of connected gear wheels 20, 21 geared respectively to the wheels 19, 17, and carried bv lever arms 23 integral with a lever 24 fitted with a cam bowl 25 engaged by a cam groove 25a in a disc 26. Normally the gears 20, 21 drive the discs 15 at the same speed as the cylinder 2, but when the grippers seize the sheet, the levers 23 are rocked to retard the motion of the discs 15, and the sheet is advanced solely by the cylinders 1, 2 so that the register of the impression cannot be disturbed by irregular motion of the grippers. When the sheet has passed from the cylinders 1, 2, the arm 24 is' rocked in the reverse direction, and the grippers regain their original position relatively to the cylinder 2.

Title: Improvements in colour photography
IPC: G03C7/30
Filed: 1938-01-19
Abstract: 511,770. Colour photography. I. G. FARBENINDUSTRIE AKT.-GES. Jan. 19. 1938. No. 1792. Convention date, Jan. 21, 1937. [Class 98 (ii)] Colour pictures on multilayer photographic material comprising silver halide emulsion layers containing dyestuff components fast to diffusion are produced by exposure, development to a black-and-white picture, fixing conversion of the silver to a redevelopable silver salt, and colour development. False colour balance may be eliminated by successive development with different colour developers acting with different speeds on the dyestuff components contained in the layers. Different colour developing substances may-be used or the speed of action of the same or different developers may be varied by additions such as sodium sulphite, sodium carbonate, sodium hydroxide or ethanolamine. The colour developer may also contain additional dyestuff components for colour correction purposes. In an example, an exposed film comprising (a) a panchromatic emulsion containing a dyestuff component fast to diffusion which yields a blue image on colour development, (b) a green-sensitized emulsion containing a dyestuff component fast to diffusion which yields a red image on colour development and (c) a non-colour sensitized layer containing a dyestuff component fast to diffusion which yields a yellow image on colour development is developed to black-and-white, washed and fixed, bleached in cupric chloride solution, washed, developed in a p-aminodimethylaniline developer, washed, and the silver image removed with Farmer's 'Reducer. Incorrect colouration may be corrected by bleaching the silver produced by colour development and re-developing with a colour developer containing a dyestuff component giving a compensating colour, for example, 1-phenyl-3-methyl-5-pyrazolone or alphanaphthol. A dyestuff component, for example acetoacetic acid anilide, may alternatively be added to the first colour developer. In another example a colour developer giving the desired alteration of colour, for example 6-methylamino- 3-toluidine, is used in place of p-amiriodimethylaniline. Specifications 2562/13, [Class 98 (ii)], 457,326, 458,400, 459,665, 460,580, 460,599, 465,823, 467,087, 478,345, 479,838, 481,275, 483,000,' 484,698, 486,848, 489,093, 489,161 and 489,274 are referred to.

Abstract: 693,516. Shaping cooked plastic pastry. BAHLSEN, W. Jan. 25, 1951 [Feb. 25, 1950], No. 1911/51. Class 87 (ii) [Also in Group VI] A continuous length of baked dough, while still in a warm and deformable state, is passed through a series of elements which shape it as required, and the shaped length of pastry is continuously conveyed from the shaping means to means which divide it into separate pieces of the desired length after it has become rigid. The length of baked dough or pastry 1 emerges from the cooker and passes through a series of rollers, Fig. 1, grouped so as to shape it progressively, the first set of rollers being as in Fig. 2 and the last set as in Fig. 7. The rolling is preferably done in a heated chamber 22. The pastry is stiffened by being passed through cooling coils 23 and is then cut up by a band saw 24. Alternatively, Fig. 9, the pastry 28, after first being trimmed to a suitable width by two circular knives 27 spaced at the correct distance, passes onto a flexible belt 26 which is then bent into the form of a trough by a pair of rollers 29, 30. Metal is mentioned as a suitable material for the belt. The belt 26 is then bent over still further by a stepped roller 31, in such a way as to enable its edges to overlap when it enters a tube 32, through which it is guided in its closed shape. The rollers are preferably in a heated chamber 36, but the tube 32 is surrounded by a cooling device 33 whereby the pastry tube is stiffened. Just before the pastry is closed into a tube, filling material may be injected through a nozzle 38. The moulded pastry is cut into lengths by opposed star knife wheels 34, 35. The tube 32 may not be round but of any shape to give a desired shape to the moulded pastry. The invention may also be carried out by using a series of groups of guide plates through which the baked dough is drawn by rollers or belts. The parts may be interchangeable so that the same machine may produce different shapes of pastry.

Abstract: 1,195,721. Automatic voltage control. JOSEPH LUCAS (INDUSTRIES) Ltd. Dec. 22, 1967 [Jan.16, 1967], No.2185/67. Heading G3R. [Also in Division B3] A regulator for use with an alternator on a road vehicle provides power through a full wave rectifier to a battery having a positive terminal 12 and a negative terminal connected to an earthed line 13, the alternator also supplying power through one or more auxiliary diodes to a positive supply line 11. When the battery voltage is below a predetermined value, a Zener diode is non- c6nductive and so no base current flows through a transistor 19. Current flowing through a resistor 21 turns on a transistor 22 and current flows in the field winding 23. When the predetermined voltage is reached, the Zener diode 17 conducts to provide base current to the transistor 19, which removes the base current from the transistor 22. By means of the feedback connection through resistor 25 and capacitor 26 the circuit oscillates with transistors 19, 22 alternately conductive, the mark-space ratio being determined by the current flowing through the Zener diode 17, which in turn is determined by the battery voltage. The arrangement is such that the mean current flow in the winding 23 maintains the battery voltage substantially constant. The method of manufacturing the regulator is described, Figs. 2 and 3 (not shown).
