Abstract: 358,187. Screens for colour photography and photo-mechanical work. GERDANOVITS, V. VON, 2, Scudier Platz, Temesvar, Roumania. Aug. 8, 1930, No. 23814. Convention date, Aug. 9, 1929. Drawings to Specification. [Class 98 (ii).] Fine line or grain screens are produced on a temporary elastic support as of rubber, which may be stretched to several times its normal dimensions before applying the screen elements, and allowed to contract again before the screen pattern is transferred to a permanent support provided with an adhesive surface. The elastic support is stretched in all directions if it is to receive a grain screen ; but in one direction only, transverse, to the lines, if it is to receive a line screen. The screen elements may comprise oil colours, or coloured resin, varnish, enamel, cellulose, nitrocellulose, &c., and may be printed, ruled, or applied as artificial threads sprayed from a nozzle and coated with the various colours. The colouring matters may comprise a permanent part and a removable part, so that strong colours may be used for the camera exposure and be subsequently weakened for viewing the picture. The screen may be formed in the sensitive layer, as by colouring in known manner either the gelatin or the silver halide particles. The screen elements may be applied simultaneously or in succession, e.g. two sets of lines of different colours may be applied at right-angles, and the squares left uncoloured may be coloured with a third colour. If the elastic support is thin and transparent it may be applied with the screen to the permanent support ; otherwise it is stripped off. The elastic support may be in the form of an endless band. Specifications 19388/95, [Class 98, Photography], 22451/12, 180,323, 231,058, and 257,501, [all in Class 98 (ii), Photographic processes &c.], are referred to.

Title: Improvements in processing mixtures of carbon black and natural and/or synthetic rubber prior to vulcanization thereof
IPC: C08K5/39
Filed: 1954-08-17
Abstract: A process for manufacturing vulcanized synthetic rubber, e.g butadiene-styrene and butadiene-acrylonitrile copolymers, comprises mixing the rubber with a large proportion of carbon black, e.g. at least 40 parts per 100 parts of rubber, and with piperidinium pentamethylene dithiocarbamate in an amount, e.g. from 1 to 3 parts per 100 parts of rubber, heating the mixture in the absence of sulphur and sulphuryielding compounds at a temperature of at least 275 DEG  F., but below the temperature at which the rubber will be injured, thereafter incorporating vulcanizing and other desired ingredients, shaping the resulting mass, and vulcanizing.  U.S.A. Specification 2,118,601 is referred to.ALSO:A process for manufacturing vulcanized natural and/or synthetic rubber comprises mixing a "rubber" selected from natural rubber, homopolymers of conjugated diolefines, and copolymers of conjugated diolefines and mono-olefines containing at least 50 per cent of combined diolefine, with a large proportion of carbon black, e.g. at least 40 parts per 100 parts of rubber, and with piperidinium pentamethylene dithiocarbamate in an amount, e.g. from 1 to 3 parts per 100 parts of rubber, heating the mixture in the absence of sulphur and sulphur-yielding compounds at a temperature of at least 275 DEG F., but below the temperature at which the rubber will be injured, thereafter incorporating vulcanizing and other desired ingredients, shaping the resulting mass, and vulcanizing.  In an example 100 parts Hevea rubber, 50 parts carbon blank, and 5 parts stearic acid are mixed in a Banbury mixer or on a two-roll mill.  To 155 parts of this master batch are added 2.4 parts piperidinium pentamethylene dithiocarbamate on a two-roll mill at 150 DEG  to 250 DEG F.  The mill temperature is then raised to 300 DEG F. and the mixture masticated for 10 minutes.  Thereafter 2 parts pine tar, 2 parts zinc oxide, 1 part antioxidant, 0.6 part accelerator, and 2.6 parts of sulphur are incorporated at 150 DEG  to 225 DEG F., and the mixture vulcanized 45 minutes at 287 DEG F.  The heat-treatment prior to the addition of the vulcanizing ingredients results in a product after vulcanization having low torsional hysteresis, a high electrical resistivity, and a high abrasion and wear resistance.  U.S.A. Specification 2,118,601 is referred to.

Filed: 1944-11-30
Abstract: 577,773. Electric couplings. PRICE, J. M. D. L. Nov. 30, 1944, No. 23966. [Class 38 (i)] A coupling for two or more wires consists of an insulating block 11 having two recesses accommodating non-rotatable nuts 15 through which are screwed terminals 19 which are electrically connected by a link 16. Wires to be connected together are clamped between the terminal heads and link 16. The block 11 may contain one or more pairs of similarly mounted terminals and is formed with bridges 24 which bear on the links 16 to prevent them from moving outwardly when the terminals are unscrewed from their nuts. The terminals carry washers 27 and the terminal heads are accommodated in wells in the block 11 which are slotted as shown in plan at 28 in Fig. 2 to facilitate connection of conductors to the terminals. Each link 16 is contained in a slot 25. The washers 27 may be formed with tongues projecting into the slots 28 to prevent them from turning with the terminals. Fig. 6 shows in plan a modified arrangement for preventing outward movement of the link which connects two terminals. The bridges 24 shown in Fig. 3 are dispensed with and the terminal heads are accommodated in a single recess 30 provided with vertical grooves 31 which lead to undercut slots 32. Fig. 11 shows the connecting link which is provided with lugs 34 which slide down the grooves 31 when the link is dropped into the recess 30. A horizontal movement of the link brings the lugs 34 into the slots 32 and so prevents vertical movement of the link. A slot 35 and a loophole 36 for the passage of conductors are provided for each pair of terminals mounted in the block. The loophole 36 may extend the full depth of the block or it may pass through the side wall of the block and be shaped to allow the passage of a circular conductor terminating in a loop or ring for attachment to the terminal. The washers 27 shown in Fig. 3 may be cup shaped and adapted to be flattened when compressed so that the diameter of the central hole is reduced which causes the washer to shrink on to the terminal screw and thus be held permanently in place under the terminal head. The nuts 15 may be claw lock-nuts.
