Patent GB-405356-A (GB)
Title: Improved method or process for the production of sound records on color or monochrome films
IPC: G03C7/22
Filed: 1932-08-18
Abstract: 405,356. Combined sound-record and colour-picture films. MURRAY, H. D., SPENCER, D. A., 118, Fulham Road, South Kensington, London, and THORNTON, J. E., 8, Hill Street, Jersey, Channel Islands. Aug. 18, 1932, No. 23135. [Class 40 (ii).] Relates to the production of sound records on multi-colour or monochrome films, of the kind in which pictures in relief are produced in a soluble coloured colloid superposed on a layer of hardened colloid, by forming a silver image in the latter layer, differentially hardening the soluble coloured colloid adjacent to the silver image, and washing out the unhardened coloured colloid. According to the invention, a sound record printed on the film is converted into a colloid relief image by the same process as that used in producing the colour pictures. Thus, in carrying out the process, the sound track is not protected from the action of the bleaching solution. The colouring matter in the sound track may be different from that in the picture areas. A process is described, in which the sound track is coated by means of a roller, weir, &c., with gelatine or other colloid coloured black by a finely dispersed pigment such as lamp black, or by an insoluble dyestuff, &c. The remainder of the film is coated with a blue-green or orange pigmented colloid, which need not be carefully confined to the picture area, but may in places overlap the black colloid without detriment, since all unwanted colloid is dissolved away by warm water treatment after the bleaching of the silver images and consequent formation of the relief images. In another process, especially suitable for producing variable area sound records, the sound track is overlaid with the same coloured colloid as is used for one series of pictures, e.g. orange red, and in order to increase the efficiency for soundreproduction, a substance such as an insoluble quinine product or aesculin may be added to the colloid, to filter off ultra-violet rays. Instead of pigmenting the colloid covering the sound track, this colloid may contain colourless substances such as lenco-bases of dyestuffs, which become dark or black on suitable aftertreatment. Alternatively, there may be used on the sound track a coloured compound which does not obstruct actinic light until it has been suitably treated ; e.g. a blue dye lake, whose colour is changed by acid or alkali to red, may be used. In a further example, the colloid covering the sound track may contain a stable green colouring matter, in addition to a blue dye lake which, after exposure and appropriate chemical treatment becomes orange, the resultant layer being black. The invention may be used in various ways with the materials and processes described in Specifications 371,077 and 377,706, [both in Group XX].

Title: Improved method of producing a coating of an oxide
IPC: C04B41/50
Filed: 1932-08-26
Abstract: A refractory layer is produced on a refractory backing by introducing into an air or oxygen blast an element or elements which form a refractory oxide on oxidation, and directing the flame upon the surface of the material to be coated.  Suitable materials are aluminium, silicon, calcium, magnesium, or alloys of any of them. The elements may be used alone or in combination with a proportion of refractory such as finely ground fireclay, firebrick, silica brick, ganister, chrome ore, chrome brick, or magnesite brick a preferred example is 25 per cent aluminium and 75 per cent, finely divided refractory.  The finely divided elements should be able to pass a mesh of 100 wires per linear inch, and the refractory material with which they may be mixed should be able to pass a mesh of 40 wires per linear inch.  When silicon is the element used it is preferred to use an oxygen-coal gas burner.  The process may be used to repair refractory surfaces while they are in use at a high temperature.  The finely divided material is preferably introduced into the blast from a hopper in which a central shaft carrying projecting vanes is arranged.  The rate of delivery of the material is regulated by the rate of rotation of the vanes.

Title: Improvements in or relating to demand regulators for respirators
IPC: A61M16/00
Filed: 1949-09-16
Abstract: 690,382. Respiratory appliances. BENDIX AVIATION CORPORATION. Sept. 16, 1949 [Nov. 24, 1948], No. 23944/49. Class 81 (ii). [Also in Group XXIX] A demand regulator for respirators is characterised by the loading spring of a first lever, connected at one end to the valve and at the other end to a second lever connected to a respiratory diaphragm, engaging the first lever intermediate its pivot and connection with the second lever. The invention also comprises means responsive to decreasing ambient pressure to operate the first lever independently of the second. The oxygen demand regulator comprises a casting 11 containing a respiratory responsive diaphragm which, when suction occurs in the chamber 30, moves a balanced lever 57 pivoted at 58 to act on a pin 55 attached to a lever 47 pivoted at 48 so that the demand valve 18 carried by the lever 47 is opened against the spring 51 and allows oxygen to pass via passages 15, 22, 23 to an injector nozzle. As the ambient pressure acting on two nested aneroids 61 decreases below a certain value, a screw 65 attached to the aneroids acts through an adjustable lever system 73, 74, on a pin 40 slidable in a bushing 36 carried by the diaphragm so that the pin opens the valve by acting on the lever 47 and eventually over-rides the effects of the diaphragm. The valve may be opened manually for testing or for slightly increasing the flow of oxygen by means of a push-button depressing brackets 89, 91 against springs 93 on two rods 90 carrying the brackets so that a rod 80, due to spring 97 between the brackets, presses resiliently on the lever 57. The push button may be rotated about an axis perpendicular to its pushing direction so that a cam on the button depresses the brackets.
Patent GB-533788-A (GB)
Title: Improvements relating to the manufacture of sheet material
IPC: B29D7/01
Filed: 1939-08-19
Abstract: 533,788. Films. DALY, A. J., HAWTIN, P. R., and SHAW, B. Aug. 19, 1939, No. 23968. [Class2(ii)] A solution of a film-forming substance in a volatile solvent is cast on to a flat polished surface of a glass plate. Sufficient solvent is removed by evaporation to allow the sheet thus formed to be stripped from the plate. The sheet is stripped from the plate and the remainder of the volatile solvent is removed from the stripped sheet. The sheet may be built up from a plurality of layers of film-forming solution, the bulk of the volatile solvent being removed from each layer before deposition of the next layer. Remaining solvent may be removed from the stripped sheet by evaporation while the sheet is held under tension in a tentering device. The film-forming substance may be a cellulose derivative such as cellulose acetate, propionate, butyrate, nitrate, acetatestearate, or other ester or mixed ester, or ethyl, propyl, benzyl, or other cellulose ether. It may be a polyvinyl compound such as polyvinyl chloride or acetate, a polyvinyl ketone, a polyvinyl ether, polymethyl methacrylate, or polystyrene. Thick transparent sheet materials suitable for use as window closures, or observation panels in aircraft, land vehicles, or gun turrets, may be obtained. When the sheet is built up from several thin layers, the successive layers may be of different thickness or composition. Some of the layers may be colourless and others may contain pigments, dyes, or other substances affecting the quality of the light transmitted, e.g. by polarizing it or excluding radiation of a particular range of wave length. One or more of the outer layers may be more water-resistant than the inner layers, thus, the outer layers may be of cellulose acetate of a higher acetyl content than that of the inner layers. The film-forming composition may comprise a plasticizer such as dimethyl phthalate, diethyl phthalate, dimethoxy ethyl phthalate, methyl phthalyl glycollate, triacetin, or dibutyl tartrate. Plasticizers which have fireproofing properties, e.g. tricresyl phosphate, or trichlorobutyl phosphate may be used. In an example, a solution containing cellulose acetate, acetone, and dimethyl phthalate is cast in a thin layer upon a flat polished glass plate with detachable metal side pieces. The layer is dried to such an extent that the solvent content is reduced to 11-13 per cent. Several further layers are then deposited upon the first layer and the solvent content of each layer is reduced before applying the next layer. The composite sheet is subjected to further drying and is then stripped from the plate and held in a tentering device in a warm atmosphere until substantially all the volatile solvent is removed.

Title: Simulation of aircraft icing and de-icing effects
Inventor: MEAD PETER HARVEY
IPC: G09B9/20
Filed: 1956-08-03
Abstract: 790,463. Simulating icing in grounded aircraft trainers. COMMUNICATIONS PATENTS, Ltd. Aug. 3,1956,No. 24004/56. Class 4. Apparatus for the simulation of aircraft icing and de-icing comprises an electrical circuit providing an electrical quantity representing a non-linear growth of ice on an aircraft, and manually operable means for modifying the circuit to produce an electrical quantity representing a non-linear decay of ice. In Fig. 1, closure of an instructor's icing switch 19 energizes a relay RL1 from a current source 14, closing contacts RLIa and RL1b. if the trainee's de-icing switch 17 is open, relay RL2 is deenergized, and contacts RL2a and RL2b are also closed. Current is thus supplied to a heating coil 13, which heats a thermistor 15. Relay RL3 is also de-energized, contacts RL3a and RL3b being closed, so that the voltage of source 14 is applied across thermistor 15 and a resistor 16. As the thermistor 15 heats up, the voltage on line 20 fed to a flight computer 8 varies non-linearly with time, and represents the build up of ice on a part of the aircraft, e.g., the elevators. This input to computer 8 is used to used to modify the press, lift and drag computations made, and also actuates a control loading device 12 which makes the trainee's control progressively heavier as simulated ice formation increases. The control may be locked solid when a predetermined simulated ice level is reached. A modulator 22 may be activated by an instructor's switch 23, whereupon the simulated cockpit is vibrated by a cam 25 driven by a motor 24 to simulate the vibration due to successive extinction and re-ignition of jet propulsion engines which may occur in icing conditions. If the trainee closes the de-icing switch 17, contacts RL2a and RL2b open, and the heating coil 13 is de-energized. The thermistor cools and a non-linear decay of ice is represented by the fall in voltage on line 20. Relay RL3 is energized after a time delay due to a thermistor 21, which heats up to a predetermined temperature before it passes enough current to energize relay RL3. When this happens, contacts RL3a and RL3b open, and the voltage on line 20 falls to zero, simulating the shedding of ice in bulk. Means similar to the above are provided for each area of the aircraft for which icing is to be simulated, e.g., ailerons, flaps, or rudder trim tabs. The characteristics of each circuit may be varied by mounting each thermistor 15 so as to be axially slidable in coil 13, thus varying the thermal coupling. An attached scale and pointer device (not shown) indicates a time constant for the heating of thermistor 15 for any axial position thereof. An output from the computer may energize relay RL1 when ambient conditions, e.g., altitude indicate that icing would occur in a real aircraft.
