Title: Improvements in tubeless tires
IPC: B60C15/06
Filed: 1956-07-30
Abstract: 812,396. Rubber-coated air-impervious fabrics. FIRESTONE TIRE & RUBBER CO. July 30, 1956 [Aug. 9, 1955], No. 23426/56. Drawings to Specification. Class 140. [Also in Groups IX and XXXIV] Individual cords of a fabric are soaked for at least 10 minutes in a solution of a rubbery composition of 100 parts by weight of neoprene mixed with 15-35 parts by weight of a compatible plasticizer, the fabric dried at a temperature not exceeding 180 F., and then calendered with unvulcanized rubber compatible with the neoprene. The soaking of the cords effects impregnation sufficient to prevent wicking of air along the cords. The fabric may be weftless or square woven cotton, rayon, nylon or like cords and the plasticizer used in the rubbery composition may comprise a mineral oil such as pine tar or rosin, a liquid hydrocarbon or a synthetic plasticizer such as tributoxy ethyl phosphate. The composition may be dissolved to provide a dipping solution of 30 per cent by weight total solids content, in an aromatic solvent such as benzene, toluene, or xylene, or in chlorinated hydrocarbon solvents such as ethylene dichloride or trichlorethylene, ester solvents such as amyl-, butyl- or ethyl-acetate, butyl formate, or ethyl propionate, ketones such as methyl ethyl ketone or isophorone, or in mixtures of the above.

Title: Improvements in or relating to the roasting of coffee
IPC: A23N12/08
Filed: 1953-08-26
Abstract: 740,786. Roasting coffee. SCOLARI, A. Aug. 26, 1953 [Sept. 29, 1952; June 8, 1953], No. 23605/53. Class 58. In roasting coffee beans, the beans are fed through an inlet 21, in a cover 2 on a casing 1, into a stationary roasting pan 3 having a perforated bottom. The beans are heated by upper and lower banks of infra-red lamps 7 and 9 and stirred by a rotating brush 52. Roasted beans leave the pan through a shutter-controlled slot 10<SP>1</SP>, a hopper 10 and a funnel 11. Refuse from the pan is collected on a plate 12 and swept by a rotating brush 13 through a flue 16 into a removable drawer 14. A rotating brush 27 cleans the lower lamps 9. All brushes are secured to a sleeve 23 rotatable about a shaft 22, which can move longitudinally to and fro to raise and lower the cover 2. The sleeve and shaft are driven by an electric motor 30 through gearing, Figs. 2 and 3 (not shown), which can be set to move the shaft and/or rotate the sleeve. A fan 20 driven by an electric motor 29 sucks, through a duct 19 and perforated disc 18, a relatively weak current of air through the beans during roasting or a relatively strong cooling current of air through the roasted beans. A reversing switch is inserted in the circuit of the motor 30 to control the to-and-fro motion of the shaft 22 through limit switches. An automatic time switch provided with an adjustable prewarning signal is inserted in the lamp circuit to control the roasting time.

Abstract: 1490440 Preparing polymer latices EXXON RESEARCH & ENG CO 30 May 1975 [28 June 1974] 23621/75 Heading C3P A process for preparing latices from organic water immiscible volatile liquid cements or dispersions of organic water insoluble polymers comprises preparing an aqueous emulsion of the cement or dispersion having dispersed particles of precursor latex size, stripping the liquid from the latex particles by creating an aerosol in a moving gas flow comprising steam as the initial continuous phase and then separating out the latex particles by impinging the latex particles on a flow of latex in a separating zone at reduced pressure, cooling and condensing the vapours from the separating zone, separating liquid from liquid-containing water which is vaporized to provide at least part of said moving gas flow. Recovered water may be vaporized in a vaporizer from which accumulations of polymer may be periodically removed by flushing with separated solvent, and two such vaporizers may be used in alternation. Withdrawn latex may be concentrated and water vaporized therefrom combined with vapour from the separation step, or condensed and combined with the separated solvent-containing water. The solvent-containing water may be filtered before vaporization, and accumulations of polymer on the filter may be periodically removed by flushing with separated solvent. Apparatus suitable for carrying out the process of the invention is described and illustrated.

Title: Pyrolytic resistor consisting of or containing carbon

Abstract: 746,258. Resistance coatings and deposits. ERIE RESISTOR CORPORATION. Aug. 19, 1954 [Aug. 21, 1953], No. 24210/54. Class 37. A pyrolytic carbon resistor comprises a varnish coating 5 between the carbon or carbonboron film 2 and the outer moulded in situ plastic casing 6. The latter must be chemically inert to the varnish coating 5 and not evolve water vapour during moulding. These conditions are fulfilled by using monochlorotriflubroethylene resin or a condensation type alkyd resin in relation to a varnish coating 5 consisting of an epoxy resin. The varnish coating 5 prevents changes in the ohmic value of the resistance film 2 during the process of moulding the plastic casing 6. It is mentioned that the varnish coating 5 may be a polyester resin. A helical groove may be cut into the resistance film, Fig. 2 (not shown).

Title: Improvements in or relating to the controls of engines driving variable-pitch propellers for aeroplanes
IPC: B64C11/42
Filed: 1947-09-02
Abstract: 642,957. Variable-pitch propellers for braking aircraft. ROTOL, Ltd., MORRIS, E. H., DANVERS, E., and GODDEN, T. E. Sept. 2, 1947, No. 24241. [Classes 4 and 114] The reversing of a propeller for braking is carried out only after the landing wheels have touched the ground. The pitch is varied by the piston 7 which is normally limited to the positive pitch range by stop 28. When making a landing the throttle lever 10 is pulled back from position 15 to slow running position 14, altering the setting of the governor. The lever when moved through the gate 16 closes switch 19, 20, and when the landing wheels touch ground switch 38 is closed, making the circuit operative. Solenoids 27, 25 and 26 then operate the corresponding valves to reverse the connections between the pump and cylinder 6, to render the governor ineffective temporarily, and to increase the output pressure of the pump respectively. This removes in succession stops 28 and 29 and subsequently restores governor control in the reversed pitch range, each of these steps being controlled automatically by plate 33 connected to the propeller blades closing contacts 34, 35, 36 and 37 at various pitch angles.

Title: Improvements in kinematograph projectors
IPC: G03B21/20
Filed: 1944-12-06
Abstract: 605,556. Kinematograph apparatus. GENERAL ELECTRIC CO., Ltd., and ESPLEY, D. C. Dec. 6, 1944, No. 24437. [Class 97 (i)] The film frame in the gate is illuminated piecemeal, during the projection interval, by a narrow elongated beam of light moved relatively to it. The invention is applicable to intermittent or continuous feed projectors. In the intermittent feed projector, shown in Fig. 1, the film 19 in the gate 18 is illuminated by a linear light source 10 an image of which is formed on the film by lenses 12, 13, 16, 17 and pivoted mirrors 14, 15. The mirrors are oscillated in opposite directions so that the image of the light source is swept across the film in the gate. The movement may be of saw-tooth form, the light beam being interrupted during the flyback periods by a shutter 21. A number of complete mirror oscillations may take place while each frame is at the gate, the film being fed during fly-back periods. Alternatively, successive sweeps of the light beam may be in opposite directions. In one form of continuous feed apparatus a pair of mirrors, similar to 14, 15, is used as an optical compensator between the film and screen, the image of the light source being focused in a fixed position at the gate. In further forms, the light source image is swept across the gate, at frame' frequency in a direction opposite to the film movement. In one such construction, one only of the optical compensator mirrors is given a saw-tooth oscillation at twice frame frequency. The two adjacent projected pictures which would otherwise be produced are brought into coincidence by superimposing on the mirror movement, or imparting to the other mirror, a square wave oscillation. Another continuous feed projector is shown in Fig. 5. A plate 52 with slits 61, 62, 63 is mounted near the film. The central slit is illuminated by a system, including mirrors 44, 48. A mirror 45 is oscillated at frame frequency between two positions in which the slits 61, 63 are illuminated respectively. Specification 522,545, [Group XL], is referred to.
