Title: Improvements in or relating to multi-colour screens for use in colour photography
IPC: G03C7/10
Filed: 1934-10-22
Abstract: 421,771. Colour photography. FINLAY, C. L., 62, St. Albans Road, Watford, Hertfordshire. Oct. 22, 1934, No. 8944. [Class 98 (ii)] In a process of preparing a multicolour screen film comprising a support and a pellicle bearing the screen, the pellicle is formed of similar material to the support and is first formed on a temporary base from which it is transferred to the support. In preparing a film according to the invention, a metal foil, e.g. of chromium-plated copper or stainless steel, is wound on a reel and the free end connected to a second reel. The foil is wound from the first reel through a coating apparatus, coated with a layer of collodion dyed green, e.g. with malachite green and auramine yellow, dried and wound up on the second reel. The foil is then re-wound past a machine for printing thereon a series of resist lines in ink, through an alcohol bath for bleaching the colour unprotected by the lines, through a red dyebath, e.g. of rhodamine and auramine, washed, dried, and wound up on the first reel. The process is then repeated for adding a set of blue-violet elements, using, for example, methyl violet and methylene blue. The screen may then be covered with a protective coating, e.g. of rubber in xylol and the foil bearing the screen passed into a bath of acidulated water, being simultaneously rolled into contact with a paper band to which the screen is thus transferred. The final support of nitro- or acetocellulose is then coated with an adhesive substratum and the screen transferred thereto. The substratum is preferably a partial solvent for the material of the screen and support, e.g. acetic acid or acetone with a small quantity of gelatin. Two, three or more coloured screens of regular or irregular pattern may be made by the process.

Abstract: 668,165. Control of several D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. April 1, 1948. [April 3, 1947] No. 9239/48. Class 38 (iii). [Also in Group XXXV] The tension in a steel strip passing from a rolling mill to a reel is maintained constant by varying the excitation of the reel motor to maintain the armature current constant and also by injecting into the field control circuit a voltage proportional to the acceleration of the mill motor. The armature of the reel motor 11 is supplied from a D.C. generator 12 through a resistor 17 so that a voltage proportional to armature current is applied to the control field 16a of an amplidyne 16, the output of which controls a second amplidyne 14 acting as a buck/boost generator in series with the supply to the field 11a of the reel motor. A second field winding 12b on the generator is also energized by amplidyne 14 to provide stalled tension when the motor is stationary. An auxiliary motor 18 has its field in parallel with the field of the mill motor 4 and drives generator 19 having its field in parallel with that of a generator 7 supplying the armature of the mill motor 4, hence any change in the field or armature currents of the mill motor produces a proportional change in the output of generator 19, across which is connected a transformer 21. A voltage proportional to the acceleration of the mill motor is therefore induced in the secondary of transformer 21, and this voltage by opposing the voltage across resistor 17 causes the reel motor to be correspondingly accelerated. In a modification, Fig. 2 (not shown), the auxiliary motor 18 has a constant field excitation, and the armature is in parallel with the mill motor armature, whilst the auxiliary generator 19 has its field connected across the mill motor field regulator 9. In another modification, Fig. 3 (not shown), the transformer 21 is omitted, and the control field of amplidyne 16 is connected to the auxiliary generator 19 through a condenser.

Abstract: 1491642 Converting rotary into reciprocating motion; screw and riut gearing NORCO Inc 9 March 1976 [31 March 1975] 09416/76 Headings F2K and F2Q [Also in Division F1] In a screw and nut gearing arrangement, the surface of a screw 18 is provided with intersecting grooves forming both a right-hand thread 24 and a left-hand thread 26, merging at each end 82, Fig. 17, whereby a nut derives a reciprocating motion by effecting a reversal of the relative axial motion at each end of its travel along the screw threads, the nut comprising an annular body which carries a ball 34 in engagement with one of the threads 24, 26, and which also carries a laterally movable ball 36 located within a guide slot 72 and capable of being shifted in a direction parallel with the screw axis, whereby ball 36 can become transferred from engagement with one of the threads 24, 26, into engagement with the other thread, so that a change becomes made in the axial direction of travel of the nut relatively to the screw, during uninterrupted relative rotation. Spring rings 64, 66, Fig. 3, may serve as detents to retain ball 36 at either end location in slot 72, and ball 36 is caused to shift along slot 72 by encountering the reversing groove path 82, Fig. 17, at the end of the thread. For one sense of relative rotation, two balls are sufficient to guide the nut past groove intersections, with the leading ball movable. To permit operation in either sense of rotation, a second movable ball 38 may be added. The nut may comprise a housing 46 and a cage 44, combined with needle bearings 40, 42. In some embodiments the pitches of the two threads (24b, 26b) may differ, Fig. 22 (not shown). The reversing path connecting the ends of both threads may have a portion of zero pitch, providing a static dwell period for the nut. With the screw driven, the nut may be held against rotation during traverse, as in Fig. 1. Alternatively, the nut may be rotated, and the screw held against rotation then reciprocates and may be used to drive the piston of a fluid pump, Fig. 29.

Abstract: 293,410. Mond, A. L., (I. G. Farbenindustrie Akt.-Ges.). April 6, 1927. Calcium, magnesium, cerium, lithium, and zinc chlorides; double chlorides and chlorides in general.-Metallic oxides or oxide-containing substances, for instance, magnesia, in suspension in fused metallic chlorides, for instance fused magnesium chloride, are caused to flow down a heated irrigation tower in countercurrent to an ascending current of a gaseous chlorinating-agent, such as hydrochloric acid or phosgene, whereby anhydrous chlorides free from oxides are obtained. By replacing the oxide-fused-chloride mixture with hydrated or partially dehydrated chlorides or double chlorides which hydrolyze when heated, such as magnesium, calcium, zinc, lithium or cerium chloride, the pure anhydrous salt is readily obtained; and by mixing powdered coke or charcoal with the initial materials, chlorine may be used as chlorinating agent. When the process is used to dehydrate hydrated salts, the chlorinating agent may be conducted round a continuous circuit which includes a dehydrating agent. As filling material for the irrigation tower coke may be used, and may serve as the resistance for internal electric heating thereof.

Cam-actuated pumps ; buffers; stroke, varying; timing devices; air, trapping; buckets; relief devices; multiple-acting bucket pumps; suction reservoirs.-A fuel pump comprises a number of cylinders 1 arranged parallel to the shaft 2 carrying the cam 8 for actuating the plungers 6. The cam consists of a roller 8 revolubly mounted on a trunnion 9 on a sleeve 10 which has internal spiral grooves engaging spiral tongues 2<b> on the shaft. The shaft 2 is driven by a shaft 14 connected thereto by tongues and grooves. The stroke of the plungers may be adjusted by sliding the sleeve 10 along the shaft 2 by means of a device 11 12, 13 operated by hand or governor. The sleeve is simultaneously adjusted angularly on the shaft 2 by means of the tongues 2b, so that the time of delivery is unaltered. The time of delivery may be varied while the stroke remains constant by moving the shaft 2 longitudinally, thereby rotating the sleeve 10. The cam acts on the plunger heads through a flexible buffer 15. The fuel is fed under pressure through suction chambers 20 conically shaped to allow bubbles to escape. The fuel passes to the cylinders through ports 21 and spring-pressed valves 22 in the plungers, and is delivered through similar valves to the engine. The valves 22 have long stems surrounded by loose sleeves 23, the inertia of which assists the opening and closing of the valves. A spring safety device 27, 28 connected to the stroke-adjusting device allows the actuating mechanism to be pushed back by the plungers if a block occurs in the delivery.

Abstract: 866,581. Moulding machines. PNEULEC Ltd. Feb. 12, 1960 [March 19, 1959], No. 9518/59. Class 83 (1). The table of a jolt-squeeze moulding machine is guided for vertical movement on a stationary cylinder which is open at its upper end and in which a piston is freely movable, jolting or jarring being effected by admitting compressed air to the upper end of the cylinder between the table and the piston while the piston is supported by a cushion of pressure air between its lower end and the bottom of the cylinder, a squeeze being applied by admitting high pressure air to the cylinder below the piston. High pressure air for jolting is admitted to between the piston 10 and the table 14 through a spring-loaded valve 22, opened by engagement of a spigot 29 with the piston 10 when it is moved upwardly by pressure of air below it. The air admitted through the valve forces the piston downwardly against the air cushion, and the table upwardly, the separation of piston and table allowing the valve to close, uncovering exhaust ports 32 and allowing the table to drop and the piston to be moved upwardly by the air beneath it to inpact the table. To apply a squeeze the exhaust port 18 is closed and additional air applied beneath the piston 10. If the supply of air to the reciprocating valve 22 is continued, jolting will continue during squeezing, alternatively the supply of air to the upper part of the cylinder is stopped so that squeezing alone is performed.

Abstract: 897,956. Electric tests. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 18, 1958 [March 22, 1957], No. 9577/57. Class 37. A method of determining the moisture content in walls, building material &c. makes use of the determination of the attenuation of an electromagnetic wave transmitted through the material. The attenuation in decibels is stated to be linearly related to the weight of water per unit volume. Typical slopes for this linear relationship are given for a number of building materials. The invention may be used to determine the effectiveness of a damp course in a building, to measure moisture in packaged materials moving on a conveyer or in a column of clay being extruded. The transmitter and a calibrated superheterodyne receiver may be positioned on either side of the body or material tested, or, when reflection from the remote surface of the body is utilized, both instruments may be on the same side. If the transmitter is modulated by a square wave at 3 kc/s., a crystal detector coupled to a selective amplifier tuned to 3 kc/s. may be used as a receiver. The transmitter and receiver may respectively be connected to one of a pair of elongated loop aerials forming a fork-like probe which may be plunged into a mass of material. Alternatively the receiver may be dispensed with and the energy lost before and after reflection from the remote surface of the material determined by use of a standing wave meter. The radio frequency should be between 2,250 and 3,500 Mc/s.
