Title: Gum plastic compositions
IPC: C08L25/12
Filed: 1963-02-21
Abstract: A gum plastic composition comprises a mixture of a hard inelastic resin, a graft copolymer compatible therewith of resin-forming monomer on a rubbery component, and a non-volatile oil which is miscible with the rubbery component and substantially immiscible with the inelastic resin and the resinous component of the graft copolymer, the weight ratio of the oil to the rubbery component being from 1:10 to 2:1, and the rubbery component and the oil comprising 3 to 50% by weight of the mixture.  The resin-forming monomer of the graft copolymer and the monomer used for making the inelastic resin may be styrene, alkyl- and chloro-styrenes, vinyl naphthalene, acrylic and methacrylic acids and their nitriles and C1-C8 alkyl esters, maleic anhydride, maleic and fumaric acids and their lower alkyl esters, vinyl and vinylidene chlorides and vinyl acetate.  The rubbery component of the graft copolymer may be natural rubber, or a synthetic rubber which is a homopolymer of butadiene, isoprene, dimethyl butadiene, 1,3-pentadiene, or copolymers thereof with one another or with other nonomers of the types specified above. Non-volatile oils specified are hydrocarbon oils of aliphatic, naphthenic and aromatic types.  The oil is preferably used in the form of an aqueous emulsion which is added to a latex of the rubbery component either before or after graft polymerization. The examples describe the addition of hydrocarbon oils to the following resin-graft copolymer blends:  (1-5) styrene/acrylonitrile copolymer resins + styrene-acrylonitrile/polybutadiene graft copolymers; (6) polyvinyl chloride + styrene-acrylonitrile/polybutadiene graft copolymer; (7) methyl methacrylate/styrene copolymer resin + methyl methacrylate-styrene/(butadiene-co-styrene) graft copolymer; and (8) styrene/methacrylic acid copolymer resin + styrene-methacrylic acid/ polybutadiene graft copolymer.

Title: Reversing valve
IPC: F16N25/02
Filed: 1950-03-21
Abstract: 689,695. Fluid-actuated valves. DEHN, S. G. (Trabon Engineering Corporation). March 21, 1950, No. 7035/50. Class 135 [Also in Group XXXIV] A reversing valve for directing fluid, e.g. lubricant, alternately in opposite directions through a circuit, e.g. a circuit incorporating measuring valves which are actuated to deliver a measured quantity of fluid each time a reversal of flow takes place, comprises a slidable, hollow reversing valve member 55, a pilot valve rod 58 slidable within the member 55 and actuated by pistons 78, 79 at either end thereof, and a slidable diverter valve member 84. With the parts in the positions shown, fluid entering the housing of the valve through a conduit 13 passes through passages 58, 64 to a chamber at the righthand end of the valve member 55 to retain the valve member in the position shown, and also through a passage 34 to a chamber 88 and thence to a pipe 14 forming part of the circuit. After passing through the circuit, fluid re-enters the valve housing through a pipe 15 and passes through a passage 46 to the right-hand side of the piston 79, moving the valve rod 58 to the left. A passage 63 is thereby opened to the supply conduit 13 whilst the chamber at the right-hand end of the valve member 55 is exhausted through passages 66, 42, causing the valve member 55 to move to the right. After such movement, fluid passes through a passage 35, moves the diverter valve member 84 to the left, and then flows through the circuit 15, 14 in the reverse direction until it arrives back at the valve housing to effect reversal. The diverter valve member provides a delay in the application to the circuit of reverse flow and thereby prevents premature reversal due to residual pressure in the circuit. As an additional precaution against premature reversal the valve member 55, immediately after it has been reversed but before the diverter valve member completes its movements, connects one end of the circuit to exhaust through either the passages 34, 41 or 35, 42. The pilot valve rod has an extension 81 which serves as an indicator and may also operate auxiliary mechanism, e.g. microswitches. The pump which supplies the conduit 13 may be operated intermittently.

Patent GB-349652-A (GB)
Title: Improvements in or relating to film-casting machines
IPC: B29C48/08
Filed: 1930-03-04
Abstract: In film-casting machines of the kind in which the evaporation of the solvent from a solution of the base, e.g. celluloid or cellulose acetate, is effected solely by heat, a gas pressure equal to or greater than the pressure of gas and vapour within the machine casing is applied to one or more of the orifices of the casing through which solvent vapour might escape, whereby the escape of solvent vapour is prevented.  As shown, the machine comprises a gelatin-coated copper band 13 passing around a water-cooled drum 12 and a drum 14.  The dope is fed on to the band from a casting box 11, and is carried by the band into the casing 15, within which heating pipes, and condensers for the solvent vapour, are located.  The band carrying the film emerges from the casing through an orifice 17, and the film is stripped from the band by a roller 19.  To prevent escape of solvent vapour through the orifice 17, air at a temperature of 65-70 DEG  C., and at a pressure greater than that within the casing, is directed on to the surface of the band near the orifice from a conduit 21, which terminates in a narrow slot 25 extending over the whole width of the band.  The slot 25 has its upper lip 27 bent downwards and its lower lip 23 bent upwards, with the result that the air stream is <PICT:0349652/IV/1> <PICT:0349652/IV/2> directed substantially parallel to the plane of the orifice 17. The arrangement thus produces a "wall" of air which prevents escape of solvent vapour through the orifice 17 while reducing the amount of air blown into the casing.  The invention may be applied to machines in which the film is cast on a single rotating drum.  Specification 281,803, [Class 2 (ii), Cellulose &c.], is referred to.

Title: Production of salts
Inventor: SIMPSON IRVINE BLAIR
IPC: C07C51/41
Filed: 1955-03-15
Abstract: A solution of a metal salt in residual oil is obtained by saponifying a natural wax which contains esters as the major component, in the presence of water and/or an alcohol, mixing a residual oil with the reaction mixture, and heating the mixture to drive off water and/or alcohol.  The residual oil has a viscosity not less than 45 S.S.U. at 210 DEG  F.  The oil containing the salt may be used as a concentrate and added to further residual oil to obtain from 0.0001 to 0.05 weight per cent of added metal in a residual oil fuel to reduce corrosion caused by vanadium in the oil.  The wax may be a Montan wax, a plant wax such as carnauba wax or candellila wax, or an insect wax such as beeswax.  The wax is saponified with a hydroxide or oxide of an alkali metal, alkaline earth metal or zinc, and the resulting salt is mixed with the residual oil, or is converted to a tin, lead, iron or zirconium salt, by double decomposition with the appropriate inorganic salt, which is then mixed with the residual oil.  The saponification preferably is performed in the presence of water and a C1 to C5 alcohol, the water and alcohol being removed by heating the oil and salt mixture to 250 DEG  to 300 DEG  F.

[Also in Division G2] An optical system for use in a colour television camera comprises a primary lens 5, a mirror 6 which splits a beam emergent from said lens into a transmitted beam and a reflected beam, and an adjustable aperture 18 effective on one of the latter beams, the transmission to reflection ratio of the mirror 6 being varied from the centre of the mirror to the periphery thereof so that the light transmitted through the aperture 18 depends on the size of the aperture to a smaller extent than if the mirror had a constant uniform transmission to reflection ratio. In a modification, the transmission to reflection ratio of the mirror 6 is varied with adjustment of the aperture 18. The mirror 6 is positioned adjacent the exit aperture of the primary lens 8. The beam reflected therefrom passes through an adjustable diaphragm to form an image I 1  on a photo-cathode 1, this image being translated into a luminance signal. The image I 2  formed by the transmitted beam is transferred to the targets 2, 3, 4 of three vidicons by a transfer lens 8 and two dichroic mirrors 9, 10. The mirror 6 may be provided with a greater reflection to transmission ratio at its centre so that the majority of light in the axial rays emerging from the lens 5 goes to form the image I 1 , and so that most of the light in the annular rays goes to form the image I 2 , The roles of the reflected and transmitted beams may be reversed when the variation of the reflection to transmission ratio of the mirror will also be reversed.
