Title: Carrier for transferring images
IPC: B44C1/165
Filed: 1975-05-05
Abstract: 1474332 Coated products H SCHONBERG 5 May 1975 [6 May 1974] 18690/75 Heading B2E [Also in Division G2] A carrier for transferring images comprises a substrate coated with a release layer and a layer of binder emulsion containing a major proportion of nitrile-butadiene rubber obtained by copolymerising butadiene and acrylonitrile. The substrate, preferably paper, coated with a release agent such as a silicone, polyethylene or polytetrafluoroethylene, is provided with a transparent image receiving layer by coating with an emulsion of butadieneacrylonitrile co-polymer, as a solution in volatile organic solvent followed by drying. A further coating of an acrylic resin (e.g. as a latex), such as polymers or co-polymers of acrylic or methacrylic acid or esters thereof or acrylonitrile, may then be applied. Alternatively a photographic emulsion layer, containing gelatine, microcrystalline silver bromide with a small proportion of silver iodide, wetting agent, dyes and hardener, may be applied on the binder layer. The image carrier is used for transferring images e.g. print or pictures from a base to a different base, by pressing the polymer-coated face of the carrier against the image which becomes bonded to the polymer, and then lifting the carrier with the secured image and pressing it, if required together with heating, against the different base, when the polymer layer together with the image, secures itself by adhesion, and finally the release-coated paper is stripped off. Altertively, the image e.g. print may be directly printed onto the polymer layer and later transferred as before to a desired surface.

Title: Improvements in or relating to yarn-tensioning devices
IPC: B65H59/10
Filed: 1954-06-25
Abstract: 761,492. Yarn tensioning arrangement. LERMONT, B. June 25, 1954, No. 18781/54. Class 120 (2). [Also in Group VIII] Spring strip is wound into two coils of opposite hand which have an inherent tendency to press against each other by their outermost convolutions, so that the interconnecting part is substantially straightened, and yarn is tensioned by being guided and cupped between the said convolutions. The yarn may travel either parallel to the coil axes (e.g. yarn 33 of Fig. 3) or, in either sense, in a direction perpendicular to those axes (e.g. yarn 67 of Fig. 5). The coil 28, Fig. 3, is wound on a mandrel 24 which slightly expands and is thus gripped by the innermost convolution and each increment of each coil is bent to the same radius so that the coils 28, 30 are " self-winding " and the pair are in equilibrium. Alternatively, coil 52, Fig. 5, may be given a tendency to unwind coil 49, by reason of, say, a gradual decrease in the radius of curvature from end 47 to end 50, or by gradual increase in thickness. of the spring strip ; and a mandrel 46 is rotatable by knob 56, to vary yarn tension, the device being held adjusted by pawl and ratchet 58, 57, Fig. 7. Shaft 53, carrying mandrel 51, is mounted in slots 54 so that the coils may always be in contact. An arm 76, secured to shaft 53, carries a yarn guide eyelet 75, Fig. 10, and the device may then be used. purely to open contacts 80 and stop the machine in the event of excess yarn tension, or may combine this function with tension control, Fig. 11. When the yarn path is at right angles to the coil axes, a slot is provided in the straight coilconnecting portion of the spring, for passage of the yarn.

Title: Improvements in or relating to a process for the preparation of substituted halogenated cyclopentadienes and adducts thereof and new compositions resulting therefrom
IPC: C07C17/30
Filed: 1947-07-17
Abstract: Substituted halocyclopentadienes are prepared by reacting a substituted cyclopentadiene with an alkali metal hypohalite, and in addition reacting the substituted halocyclopentadiene with a dienophile according to the Diels-Alder synthesis.  Dienophiles mentioned include maleic anhydride, cyclopentadiene, methylcyclopentadiene, butadiene, styrene, indene, dicyclopentadiene, phenylacetylene fulvenes and quinones.  In examples (1) a hexane solution of methylcyclopentadiene is treated with alkali sodium hypochlorite to form methylpentachlorocyclopentadiene; (2) the product of example (1) is added to cyclopentadiene and after standing 3 days the Diels-Alder adduct is formed; (3) indene and methylpentachloropentadiene are allowed to stand as in example (2) to form an adduct; (4) maleic anhydride and methylpentachlorocyclopentadiene are mixed and heated in an oil bath to form an adduct.  The compounds are useful as insecticides.ALSO:Substituted halocyclopentadienes are used as insecticides.  In an example, the Diels-Alder adduct of methylpentachlorocyclopentadiene and cyclopentadiene is dissolved in kerosene and used as a spray.  Alternative compounds specifically mentioned for this purpose are the adducts of methylpentachloro-cyclopentadiene with isoprene, of ethylpentachloro-cyclopentadiene with cyclopentadiene, and of methylpentachloro-cyclopentadiene with butadiene.  The above compounds as well as other adducts may be utilized in the form of oil sprays, dusts, aqueous emulsions, or aerosols, either alone or in association with any other desired toxicants.

Title: Coke oven gas purification process
IPC: C10K1/08
Filed: 1949-07-21
Abstract: 664,733. Revivifying gas-purifier liquor. KOPPERS CO., Inc. July 21; 1949 [Nov. 23, 1948], No. 19231/49. Class 55 (ii).. Coke oven gas is scrubbed with alkaline aqueous absorbent which is then regenerated under sub-atmospheric pressure, evolved vapours being scrubbed with a different absorbent, thus reducing the volume of gas to be handled by a vacuum pump which maintains the sub-atmospheric conditions in the actifier or regenerator. Gases from oven 10 are sprayed with liquor in a collecting main 12, traversing thence a primary cooler 18, tar extractor 21 and absorber 26 supplied with a solution, e.g. sodium carbonate, from the bottom of an actifier 30 through a cooler 32, all the hydrogen sulphide, hydrogen cyanide, and ammonia content of the gas being absorbed. The solution collecting at the bottom of the absorber ascends round baffles 33 in counterflow with tar pumped from a tank 16 below a downcomer 15 at the outlet of the main, naphthalene being thereby removed from the solution which is pumped to sprayers 40 at an intermediate point in the actifier. At the base the fouled solution is indirectly heated by a reboiler 41 through which rela: tively hot flushing liquor is circulated by a pump 25. By means of a vacuum pump 72 the pressure within the actifier may be as low as 4 ins. mercury; ammonia, hydrogen sulphide and hydrogen cyanide emitted pass through a deflegmator 43, which condenses steam returned as water to sprays 46, to a wash oil spray chamber 54 to remove naphthalene traces before treatment in an absorber 60 with ammoniacal liquor circulated by a pump 61 through a cooler 62 to sprays 64. Liquor pumped through reboiler 41 is subjected to the reduced pressure of the actifier in a flash tank 50, water vapour therefrom passing to the actifier to make up for moisture not returned by deflegmator 43. The liquid is returned by a pump 57 to sprays 14 in the main, a portion being diverted into the circuit of the secondary absorber 60. Compounds formed in the absorber by reaction of ammonia with the sulphide and cyanide remain in the solution passing to an ammonia still 70. Residual gases flow from the absorber through a water separator 67 to an acid washer 71 for removal of traces of ammonia before passage through the vacuum pump. Gases from still 70 are delivered to an ammonia saturator 75. Specification 209,379, [Class 55 (ii)], is referred to.

Title: Improvements in automatic lock slider for slide fasteners
IPC: A44B19/30
Filed: 1947-07-21
Abstract: 631,042. Sliding-clasp fasteners. CONMAR PRODUCTS CORPORATION. July 21, 1947, No. 19469. Convention date, April 2, 1943. [Class 44] A slider for a sliding-clasp fastener carries a twoarmed locking lever, one arm of which is adapted to be engaged by the fastener elements in such a manner that the other arm of the lever, which carries a locking tooth, is urged into engagement with the elements. In the form of Fig. 1, the lever L is fulcrummed at F on a lug 38 on the slider and has a nose part 34 in contact with the elements. As the slider tends to slip down the row of elements, the frictional force of the elements on the nose 34 turns the lever so that the tooth 32 enters into locking engagement with the elements. A pull tab 44, secured in a slot 40 in the lever, is adapted to release the tooth 32 when pulled to draw the slider down. The elements are deflected by the nose 34 into a depression 46 formed in the back wall of the slider to increase the pressure on the nose 34. In a modification, the depression is omitted but sufficient clearance is allowed between the slider and the elements to provide for some deflection under the nose 34. In assembling the slider the lever is installed in the opening in the front wall of the slider and retained in position only by the fastener elements. In another form, the lug 38 on the front wall of the slider is extended to form a complete loop embracing and providing a fulcrum for the lever the nose 34 of which is broad enough to contact both rows of elements. In the form of Figs. 7 and 8, the lever L has fulcrum portions 78 formed at the base of a wing- shaped contact nose on which the direct pressure of the elements is effective to tilt the locking tooth 32 into engagement with the elements. The portions 78 bear in recesses 76 in the front plate of the slider. An embracing loop 56 is provided. The lever is retained by swaged ears 68. The two plates of the slider are pressed and spot-welded together at 26. In a modification for a die-cast slider in which a non-round rivet is formed on one part and received in a non-round hole in the other, the lever is mounted in a manner similar to that shown in Figs. 7 and 8 but without the loop part 56.
