Title: Improvements in or relating to light-sensitive photographic materials
IPC: G03C1/835
Filed: 1939-12-06
Abstract: 537,081. Photographic anti-helation layers. DU PONT FILM MANUFACTURING CORPORATION. Dec. 6, 1939, No. 31648. Convention date, Dec. 13, 1938. [Class 98 (ii)] Light-sensitive photographic material comprises a transparent support carrying a lightsensitive layer on one side and an anti-halation layer on the other side comprising an antihalation dye or pigment and a polymeric nitrogen compound which contains one or more amino groups and which is insoluble in water and 5 per cent. ammonium hydroxide solution but which is soluble in 5 per cent. aqueous acetic acid, preferably in 2 to 5 per cent. aqueous acetic acid. The light-sensitive layer may be a panchromatic or orthochromatic emulsion layer. The nitrogen compound may be deacetylated chitin ; an acid-soluble reaction product of a protein with a carboxyl compound such as a lower aliphatic aldehyde or ketone and an amine having less than nine carbon atoms in which the amino-nitrogen is joined to the aliphatic carbon; an amino cellulose soluble in dilute acetic acid and containing an amino-nitrogen atom removed from the cellulose nucleus by at least one carbon atom; cellulose amines soluble in a stoichiometrical amount of 5 per cent. acetic acid and containing directly attached to the cellulose nucleus from 0.5 to 1.5 amino nitrogens per glucose unit; the reaction products of vinyl ketone polymers with amino compounds ; the products obtained by treating resins having ketone groups with excess ammonia or amines and catalytically hydrogenating; polymeric amino alcohol esters of acrylic and substituted acrylic acids ; and polymeric alcohol methacrylates. The compounds may be used singly or in admixture. Resinous reaction products of phenols, aldehydes and ammonia or primary or secondary amines may be used, for example the reaction product of m-cresol, formaldehyde, and dimethylamine. Examples specified are piperidylmethylzein, dimethylaminomethylzein, dimethylaminoethylzein, and dicyclohexyl aminoethyl methacrylate. The dyes may be water-or spirit-soluble and may be blue, green, yellow, magenta, or red, or may be used in combination to give black or deep blue. Black or red antihalation layers are used with blue-sensitive or orthochromatic emulsions, and black, green or deep blue with panchromatic emulsions. Numerous dyes are specified. Naturally occurring pigments, metallo-dye complexes, and inorganic coloured compounds may be used. The layer may be applied by dipping, transfer, spraying, beading, or immersion beading. The antihalation layer may be rendered soluble before fixing by treatment in an acetic or citric acid bath, such as a stop bath. The emulsion layer may contain sensitizers such as cyanines, carbocyanines, pseudocyanines or cyazine bases or salts. The antihalation layer may be permanent, the dye concentration being reduced and alum added to the coating solution. Specifications 475,131 and 475,132, [both in Group IV], are referred to. Reference has been directed by the Comptroller to Specification 517,559.

Title: Improvements relating to manufacture of steel in a rotary furnace
IPC: C21C5/32
Filed: 1957-10-15
Abstract: Steel is produced by refining pig iron in a basically lined rotary furnace using an oxidizing gas or gaseous mixture injected from above the bath, gas loaded with finely divided basic material being directed on to the lining of the rotary furnace or on to the melt close to the lining.  The basic material may be one or more of iron oxide, manganese oxide, magnesian lime, or magnesian limestone.

Abstract: 521,250. Stapling &c., POLLAK, J. E. (Brehmer, Geb.). Nov. 9, 1938, No. 32561. [Class 89 (iii)] A method of connecting paper blocks, wooden boxes or the like comprises the use of a single piece of wire 12, Fig. 1, which is finally hooked at both ends. The wire 1 is fed at 2 to cutters 4, 5 and a stitcher head 6, where it is received in a groove in a bending block 7. Bending and driving mechanism is shown at 8, 9. The projecting end of wire 11 forms a hook which penetrates entirely into the work. The longer end of wire is adjustable to correspond with the thickness of the material. After being bent the wire 12 is driven by the driver 9 and projects beneath the work, Fig. 5. At this point a support 13 has an opening 14 through which a movable plunger 15 operates to deflect the point of the staple and drive it entirely into the work. The plunger 15 is actuated by a slide member, the forward end 16 of which has an oblique actuating surface.

Abstract: 1,079,613. Removing dust from air. NATIONAL DUST COLLECTOR OF CANADA Ltd. Aug. 12, 1964 [Sept. 18, 1963], No. 32817/ 64. Headings B1R and B1T. Dust-laden air enters at 26 and passes over the surface of water 28, upwards through filter bed 34 and then through separator means, comprising vertically extending, parallel, Z- shaped vanes 64 (Fig. 3 not shown) which remove any entrained water droplets, to outlet 22d. An electric fan 38 is fitted on the outlet. The water level in sump 22b is maintained by float-controlled inlet 30a and overflow 30b. Bed 34 comprises spheroids, and sufficient water is entrained by the air stream to maintain a turbulent layer of water above the bed, whose depth is limited by overflow 36. Most of the dust is trapped by this layer and eventually accumulates in sump 22b, which is periodically drained and cleaned. Residual water droplets are caught by vanes 64, drain down through holes 56b in the vane-supporting plate 56 into channels 70 and are thence returned (Fig. 2, not shown) either to sump 22b or to the filter bed 34. Vanes 64 may be removed through access doors 61, and either merely rest between flanges 58, 60 on plate 56 (Fig. 4, not shown), or are recessed at their lower corners to interlock therewith (Figs. 5 .. 7, not shown). U-section rubber bumpers 54, 62 abut the outlet sides of vanes 64. Channels 70 may be rubber; vanes 64 may be aluminium or stainless steel.

Abstract: 862,134. Fluid-pressure brakes. CLAYTON DEWANDRE CO. Ltd. Dec. 15, 1959 [Oct. 16, 1958], No. 33074/58. Class 103 (1). In a vacuum-operated braking system for road vehicles comprising a mechanical transmission 1, 1a between the brake pedal 2 and the rear wheel brakes boosted by a master servo 3 supplied with vacuum from a reservoir 4, vacuum servo devices 5 actuate the front wheel brakes and a separate reservoir 6 supplies vacuum thereto and a reaction valve 7, actuated mechanically by link connection 8 by the brake pedal 2, controls operation of the front wheel servo devices 5. The two brake reservoirs 4 and 6 are charged from a common source through separate non-return valves 9. The above system enables advanced operation of the front wheel servo devices 5 thus providing more even wear of the brake linings. In an alternative arrangement (not shown) the reaction valve 7 may be mechanically linked to the brake pedal independently of the rear wheel brake transmission 1, 1a. Specifications 549,692 and 578,314 are referred to.

Filed: 1946-11-08
Abstract: 630,498. Coated and proofed fabrics. WING- FOOT CORPORATION. Nov. 8, 1946, No. 33238. Convention date, June 24. [Class 140] [Also in Group XXIX] Woven fabric, the fibres of which are of colddrawn polyamide, has the interstices closed with a polyamide interpolymer. The fabric may also be coated with a polyamide interpolymer. The polyamides capable of being cold-drawn are characterised by a linear structure of regularly recurring like units whereas the interpolyamides have a linear structure of unlike units. The interpolyamides and polyamides are prepared by known methods such as the condensation of diamines and dicarboxylic acids or the condensation of monoamino-monocarboxylic acids, the interpolymers being obtained by using mixtures of acids or amines of different chain length. Many examples of acids and amines are given. The interpolyamides may be applied to the fabric by calendering or as a solution dissolved in a suitable solvent, e.g. ethyl alcohol, and the solvent removed. The treated fabric may be heat sealed and used for making containers.
