Title: Improvements in or relating to films for sound photography
IPC: G03B31/02
Filed: 1929-07-30
Abstract: 331,122. Kodak, Ltd., (Assignees of Stewart, D. H.). March 25, 1929, [Convention date]. Photographic records.-Re lates to photographic sound records in which portions of film bearing different records are joined end to end. According to the invention, in order to prevent an abrupt change during sound reproduction, when the junction of the records is reached, this part is obscured by a strip of flexible material which is so formed as to cause a gradual reduction in the volume of sound as the junction is approached, followed by a gradual rise in volume when the transition from one record to the other has . occurred. The density of the obscuring strip is preferably so graded that it is a maximum at the point where the sound records join. Fig. 2 shows a strip 17 of graded density and of triangular form, attached by adhesive to two joined films 10, 11 bearing different sound-records 14, 16, the apex of the triangle being arranged over the junction. An alternative form of strip 18, rectangular in shape and of graded density, is shown in Fig. 5. To facilitate alignment of the strip 17 or 18 with the sound record, it may be so mounted on a detachable paper support 19 that when the edge 20 of the paper is in line with the edge of the film the obscuring strip is properly located. For convenience, a number of the strips may be mounted in line on a long support 19, which can be rolled up.

Title: Method of removing dusts and condensable substances from hot gases
Inventor: BADE ERICH
IPC: B04C5/20
Filed: 1963-06-12
Abstract: 982,719. Condenser systems; cyclone separators. POLYSIUS G.m.b.H. June 12, 1963, No. 23491/63. Headings B1B and B2P. [Also in Division F4] Condensable substances are removed from hot gases containing dust, e.g alkalis are eliminated from the flue gases of a cement kiln, by removing the dust from the gases while the condensable substances are in the vapour state, and then bringing the gases into contact with cold, fine-grained solid material to condense the condensable substances, the condensate being withdrawn from the system as a deposit on the fine-grained solid material. The gases, freed from the condensable substances, are used to preheat raw material to be processed, e.g. the charge to a cement kiln. Flue gases emerging from rotary kiln 1 are passed through pipe 3 into cyclone 4, and the hot dust is separated and discharged via pipe 5 into pipe 6, which supplies the preheated material to be processed to the kiln. The gases leaving cyclone 4 through pipe 7 are mixed with cold dust supplied from hopper 8 or electrostatic precipitator 10. The suspension of dust in the gases is passed to cyclone 13. The dust which is discharged through pipe 14 has a high concentration of alkalis, and may be used as a fertilizer. The gases leaving cyclone 13 flow into vortex shaft 15 where the raw material for the kiln, supplied from hopper 30 and shaft 23, is preheated. The gases pass from shaft 15 into cyclone 19 and 20 where entrained solid material is separated, and returned to shaft 15 via pipes 34 and 35. The gases leaving cyclones 19 and 20 pass into vortex shaft 23 which is connected to two cyclones 24, 25. The gases flowing out of these last two cyclones pass through electrostatic precipitator 10 and are then discharged by fan 33.

Title: Improvements in graft polymerization using ionizing radiation as the graft polymerization initiator
IPC: C08F291/18
Filed: 1957-07-24
Abstract: In the process of producing graft polymers by subjecting a polymer to ionizing radiation and to contact with a monomer polymerizable by free radicals, the monomer is, during the contacting of the polymer and monomer, additionally contacted with a polymerization inhibitor capable of substantially inhibiting homopolymerisation thereof while maintaining the polymer on which the graft is being formed substantially free from the action of the polymerization inhibitor. The inhibitor may e.g. be more soluble in the monomer phase than in the polymer or may more readily disperse by diffusion in the monomer phase than in the polymer phase, inhibitors specified being polyhydric phenols, benzoquinone, air and oxygen.  In examples, plates of polyvinyl chloride are swollen in acrylonitrile and the swollen plates irradiated while partially immersed in liquid acrylonitrile in the presence of air.  Other polymers and monomers which may be used are referred to in Specifications 801,528 and 809,838.ALSO:In the process for producing graft polymers by subjecting a polymer to ionizing radiation and to contact with a monomer polymerizable by free radicals, the monomer is, during the contacting of the polymer and monomer, additionally contacted with a polymerization inhibitor capable of substantially inhibiting homopolymerization thereof while maintaining the polymer on which the graft is being formed substantially free from the action of the polymerization inhibitor.

Filed: 1961-06-29
Abstract: A hardenable composition comprises a mixture of (1) a glycidyl polyether and (2) a curing catalyst therefor comprising from 0,5 to 50% by weight, based on the weight of polyether, of a nitrogen co-ordinated boron compound of the formula <FORM:0927006/IV(a)/1> wherein R is selected from -CH2-CH2 and -CH(CH3)CH2-and R1 and R11 are selected from hydrogen, alkyl radicals, cycloalkyl radicals and aryl radicals.  A hard, cured resinous product is produced by heating this mixture within the range 80 DEG  to 150 DEG C.  The glycidyl polyethers are made by reacting at least one polyhydric phenol and an epihalohydrin in an alkaline medium.  Suitable phenols are polynuclear phenols such as bisphenol 'A' and 4,41-dihydroxydiphenyl methane, in admixture with which may be used, for example, 4,41-dihydroxy diphenyl sulphone. Solutions of the glycidyl polyethers and curing catalysts can be applied to electrical wires, cables, coils and windings as potting, impregnating and coating resins and varnishes.  The compositions comprising glycidyl polyethers and curing catalysts are adhesives.  They can also be admixed with solids such as silica, titania, glass fibres, wood flour, zirconia, graphite and calcium silicate.  Amounts of up to 50% of the composition of other resins such as phenolics, polyesters, glycol maleates and alkyd resins can be admixed with the glycidyl polyethers.ALSO:Alkanolamine borates of the formula <FORM:0927006/IV(a)/1> where R is -CH2-CH2 or -CH(CH3)-CH2- and R1 and R11 are hydrogen atoms, alkyl radicals, aryl radicals or cycloalkyl radicals are made by reacting three mols of a mono-alkanolamine for each mol of boric acid or boric ester at an elevated temperature of about 60 DEG C. to 140 DEG C.  The water or alcohol by product may be distilled off during the reaction.  When boric acid is used, azeotroping solvent such as benzene, toluene, and xylene may be used to remove the water.

Title: Improvements in dehydrohalogenation of hydrocarbon halides
IPC: C07C1/30
Filed: 1963-06-13
Abstract: Olefins are produced from hydrocarbon halides by heating at 100-700 DEG  C. in the presence of carbonaceous material which has been treated with a free -O2 containing gas, e.g. air, at 300-700 DEG  C. for 1 sec. to 1 hr.  Dehydro-halogenation occurs with only tertiary halides at 125-200 DEG  C., and with secondary halides also at 225-300 DEG  C.  C3-C18 hydrocarbon halides, particularly monohalides, e.g. of alkane, cycloalkanes, and alkylcycloalkanes may be used.  (Examples are listed.)  The process may be carried out at sub-, super- or atmospheric pressure, in either (a) liquid phase by heating the halide and carbon together such that the olefin distils off, any halide remains, and hydrogen halide gas as absorbed or vented, or (b) gas phase by passing halide vapour through a bed of carbon.  An inert carrier gas may be used. Carbon in amounts of 0.01-25% of halide is used in a batch process, or 0.01-10 volumes of liquid per volume of carbon is used per hour in a continuous process. The treated carbon may be of particle size 6-325 U.S. mesh; carbon black pigments, or conventionally activated carbon, e.g. charcoal, are suitable as starting materials.ALSO:Particulate carbonaceous material is heated to 300-700 DEG  C. in a free-O2 containing gas for 1 second to 1 hour.  Carbon black pigments, or conventionally activated carbon, e.g. charcoal, may be used.  The gas may be air with or without an inert diluent. The material is used as a catalyst in the dehydrohalogenation of hydrocarbon halide to form olefins.

Title: Improvements relating to gas turbine power plant installations
IPC: F02C7/047
Filed: 1947-08-27
Abstract: 637,598. De-icing air intakes. KENT, N. H. Aug. 27, 1947, No. 23770. [Class 4] [Also in Group XXVI] This invention relates to a gas-turbine plant having anti-icing means comprising a combustion chamber separate from the engine combustion equipment which is supplied with air tapped off from the compressor. In one arrangement the separate combustion chamber is located in a conical fairing forming a stationary extension of the compressor rotor and the hot gas is distributed through hollow struts which extend transversely of the air intake passage to the compressor. In another arrangement, the hot gas is distributed through passages in the rotor and stator blades of the compressor. Air, tapped from an intermediate stage of a compressor 11, Fig. 2, is led through ducts 19, an annular manifold 22, hollow struts 23 and a collector space 24 to a combustion chamber 26 located in a conical fairing 18. Fuel from the normal engine supply or from a separate system is supplied to the combustion chamber 26 through an injector 27. The hot gases from the combustion chamber flow through struts 30 to an annular chamber 31 formed in the leading edge of the nacelle 10. Both the struts 30 and chamber 31 are provided with outlets 32 through which the hot gases pass into the air flowing through the compressor intake 16. The air supply valves 20, the current to the sparking plug 28 and the supply of fuel to the injector 27 may be arranged for simultaneous operation. In a modification, the air is tapped from the air passages in the combustion chambers of the engine. In multi-engined aircraft each engine may be provided with a separate combustion chamber, the air and fuel supplies to which may be interconnected so that hot air may be supplied to an engine even though it is not running. In another modification, Figs. 4A and 4B, air is taken from the stator of a high pressure stage of the compressor 11 through ports 73, slots 71, radial passages formed between plates 70, ports 74, collector manifold 75 and conduit 76 to the inlet 80 of the separate sheet metal combustion chamber 81. The slots 71 are formed in rings 67b which space the thin disc-like members 63 carrying the blades 64. The hot gases leaving the combustion chamber 81 pass through ducts 85 to hollow struts 90 which discharge into a manifold on the outside of the compressor casing connected to a duct 93 at the inlet edge of the struts 90 and hollow stator blades 97. The hot gas from the duct 93 passes into the airstream through ports 94. The hot gas from the hollow stator blades 97 passes into hollow disc structures 65 and then into hollow rotor blades 66 which it leaves at the tips. A pipe 102 connecting the structures 65 is formed between two nested sleeves 103, the outer of which has ports communicating with passages formed between radial flanges 104 formed on a two-part spacer ring 67a to supply hot gas through ports 105 to the stator blades 69. Specification 618,224 is referred to.

Title: Improvements in and relating to apparatus for the photo-electric reproduction ot sound films
IPC: G11B7/00
Filed: 1937-09-02
Abstract: 494,201. Optical sound - reproducing apparatus. KOLB, O. K. Sept. 2, 1937, No. 23996. [Class 40 (ii)] Apparatus for the photo-electric reproduction of sound films of asymmetric types comprises optical means for producing an enlarged image of the sound track upon a slit-bearing mask and optical means located at or immediately behind the mask serving to divide the flat light pencil passing through the slit at the enlarged focal image plane before it diverges and to divert each light pencil associated with opposed lateral zones of the sound track to a separate photo-sensitive reproducing element. These elements may be constituted by selenium cells or self-generative or barrier layer cells. Alternatively, the two photo-sensitive elements may be formed as cathodes in a single common envelope. As shown in Fig. 1, light from a lamp 0 is focused by means of the condenser lens 1 on a push-pull or like sound track 20 on the film 2. The light passing through the film is projected by means of the objective lens system 3 so as to produce a magnified image of a portion of the sound track on a mask 4 provided with a slit lying at right angles to the film traverse. The flat pencil of light passing through this slit falls on a pair of mirrors 50, 51 which divide it into two separate pencils which are diverted so as to fall respectively on photocells 60, 61. The intersecting ridge 52 formed by the mirrors is adjusted by a screw 53 and nut 54 so as to lie exactly on the division between the images of the two lateral zones of the sound track formed at and upon the slit in the mask. Fig. 2 shows a modification in which the mirrors 50, 51 are replaced by twin total reflection prisms 55, 56. According to further modifications, the mirrors 50, 51 instead of being plane may be formed as cylindrical surfaces, Fig. 5 (not shown) or may be replaced by parallel or acutely inclined mirrors which divert the respective light pencils in parallel or slightly divergent directions on to the photocells, Fig. 3 (not shown). If desired, a lens may be placed in juxtaposition to the mask 4 so as to concentrate the light pencils passing through the slit. In a modification of the arrangement shown in Fig. 2, the slit-bearing mask is formed by providing an opaque coating on the front face of each prism, a continuous slit extending across both prisms being formed in this coating. Fig. 8 shows a further modification in which the light passing through the film is projected on to a slit-bearing mask formed as coatings 503a, 504a, on the ends of bent glass rods 503, 504 which direct the light beams on to photo-cells 60, 61. All the faces of these rods are coated with a metallic reflecting layer with the exception of the exit faces 503b and 504b. The photo-electric systems may be connected to an electrical system as described in Specification 462,195 whereby alternative reproduction of normal or asymmetric films may be effected.
