Patent GB-190704932-A (GB)
Title: A Method of Producing Photographs in Natural Colours
Inventor: BRASSEUR CHARLES LOUIS ADRIEN
Filed: 1907-02-28
Granted: 1908-02-27
Abstract: 4932. Brasseur, C. L. A. March 1, 1906, [date applied for under Patents Act, 1901]. Colour photography.-Relates to a modification of the grain and screen processes enabling diapositives to be obtained from a grain or from a line negative, and further enabling grain positives to be obtained from a line negative. The coloured grain negative is not copied or printed by white light in the ordinary way, but three pure colours are used corresponding to three narrow bands of the spectrum, as illustrated in Fig. 6. The dotted lines show Abney's colour-mixture curves which overlap. The pure colours are obtained in practice by means of filters which transmit only the required light. To test the colours of the filters and the relative exposure times required in printing or copying, two screens ruled with the negative taking and positive viewing colours ara superposed crossways, and a panchromatic plate is exposed, using the pure colour filters. The resulting negative should show three equal shares, as illustrated in Fig. 10, if the colours are correctly chosen and the relative exposure times correct. To obviate giving three exposures through three filters, the colours are arranged in bands (or sections in the case of copying lenses), the sum of the surfaces of the three different colours being proportional to their respective exposure times, as illustrated in Fig. 12. In printing or copying, the filter is moved backwards and forwards through the complete width of these three bands. With line plates, the negative or positive, as the case may be, is displaced laterally through the width of three lines to ensure that each series of three lines affect the corresponding series on the positive plate, the equivalent method with grain plates being a slight diffusion of the image. The present method can be utilized for making negatives for three or four colour printing. Specifications No. 8390, A.D. 1896, and No. 15,185, A.D. 1905, are referred to.

Abstract: 14,025. Brooks, R. A. June 18. Waste-preventing valves.-Relates to waste-preventing flushing-valves in which the valve closes against the pressure of the flushing-liquid and in which the flush does not take place until the operating-push is released. The valve D is situated inside a subsidiary casing C, into which the flushing- liquid has access through the tubular valve stem d<2> whereby the valve is closed, as shown. The upper part B of the casing is fitted with a sliding cup F connected with a push G<2> and with a pair of vent valves e', e<2>, which control an aperture in the top of the subsidiary casing C. Within the cup F and rigidly suspended by rods from the top cover G is arranged a piston block G<1> provided with a check valve g<7> and with a leakage-control device consisting of an adjustable slotted pin g<2>. A removable cap g<4> is provided so that a screwdriver can be inserted to adjust the leakage by screwing the pin g<2> into or out of the block G<1>. The cup F is charged with oil, glycerine, or other control liquid not readily frozen. When the push is pressed down, the control liquid passes through the check valve g<7> to the underside of the piston. When the push is released, the vent valve e<2> by its movement allows the liquid behind the valve D to escape by means of the reduced part E of the valve stem and thence through the port c<3>, thus allowing the valve to be opened by the flushing-fluid. Meanwhile, under the action of the spring g<9>, the cup F rises gradually as the control-liquid escapes through the slotted pin g<2>. The flush continues until the vent valve e<1> closes the aperture at the top of the subsidiary casing C.

Title: Improvements in Variable Speed Gears.
Inventor: VEULLE FREDERICK HENRY DE
Filed: 1908-07-20
Granted: 1909-04-29
Abstract: 15,326. Veulle, F. H. de. July 20. Variable-speed and reversing gearing.-In changespeed and reversing gearing of the class comprising oscillating disks transmitting motion to spindles as described in Specification No. 6344, A.D. 1908, means are employed to secure uniformity of motion &c. The driving-shaft A, Fig. 1, carries a cam B, which engages and drives pins E projecting from osciliatable disks D carried in ball bearings in a plate C mounted around the shaft A. The oscillating motion of the disks D is transmitted in a variable manner to spindles K carrying loose gears L meshing with a central pinion 0 on the driven shaft O<2>. Motion in one direction is imparted to each gear L through a ratchet clutch or through a positive clutch thrown intermittently into action as described in the Specification mentioned. The connexion between the disks D and spindles K will be understood with reference to Fig. 6. An arm J, secured to each spindle K, carries at its end a pin H engaged and actuated by a slot D<2> m its disk D. The speed is varied by rotating the plate C, Fig. 1, slightly, thereby in effect removing the axis d, Fig. G, of each disk D farther from its spindle K, and sliding the pin H farther out in the slot D<2>. This slot D<2> is curved, to secure uniformity of motion, so that if a is the axis of the gear and b is the axis of the pin H the angle a b d is a right-angle. The pin-and-slot ''straight-line motion " of Fig. 6 being inconvenient, the link-work arrangement of Figs. 7 and 1 is used in practice. It is possible to fix a pin F upon a disk D and to connect the pins H, F by a link G in such a manner that the angle a b d remains a right-angle. The positive clutch connexion between the spindles K and gears L is necessary when reversed driving is required. The clutches are brought into action for a short time when required through the agency of internal rods T, rocking levers S, and other rods R'. A cam Q, Fig. 4, on the shaft A operates the rods R' through blocks P sliding in the plate C and through bell-crank levers P' engaging the elongated heads R of the rods R'.
