Abstract: 1311102 Electro-deposition of a photoconductive layer RICOH KK 13 May 1970 [10 June 1969] 23053/70 Heading C7B [Also in Division H1] A photo-conductive layer for electrophotography is formed on a conductive support by electro-deposition of a suspension of an insulating resin and zinc oxide in a dispersion medium at a current density of 0À5-2mA/dm<SP>2</SP> and at a temperature of 10C. to 25C. to produce a layer less than 40 microns thick. 15 to 30g of resin and 400 to 1000cc of ZnO. In the embodiments the dispersion medium may be toluene, trichloroethane, methylene chloride, xylene, heptane, octane, tetrachloroethylene, ethylene dichloride or water, whilst the resin may be acrylic, styrenated-alkyd or copoly vinyl acetatecrotonic acid, other resins also being specified. If a water-soluble resin is used, triethanolamine is added as an emulsifier; for organic solutions, manganese or cobalt napthenate are added as driers. The electro-deposition is performed between the conductive support and another electrode, the other electrode may be the container for the suspension or in the case of a cylindrical support, a cylinder surrounding the support. The support may be Al or paper with polyvinyl alcohol applied thereto. The other electrode may be Al or graphite. If paper is used then it secured to a metal plate prior to electro-deposition. The zinc oxide particles absorb resin and according to the solvent used become positively or negatively charge and migrate to the appropriate electrode.

Title: Process for treating the meat of warm-blooded animals

Filed: 1969-05-12
Abstract: 1,263,389. Coating and flavouring meat. HAARMANN & REIMER G.m.b.H. 12 May, 1969 [10 May, 1968], No. 24070/69. Headings A2B, A2E and A2U. Fresh meat of warm-blooded animals is coated with a mixture of glycerides of paraffinic and/or olefinic carboxylic acids with from 8 to 22 C atoms, the mixture comprising from 2% to 30% by weight of one or more monoglycerides and from 98% to 70% by weight of one or more diglycerides and/or triglycerides. The glycerides may be derived from aliphatic carboxylic acids free of acetylenic unsaturation. Preferred glycerides are those of naturally occurring unbranched carboxylic acids such as the uniform and/or mixed glycerine esters of caprylic, caproic, myristic, palmitic, stearic, arachic, oleic, linolic, linoleic and erucic acids. Examples of suitable triglycerides are peanut oil, rape oil and a mixture of olive and rape oils. The coating mixtures, which are gel-like at room temperatures, change to liquid form during application to the meat, which may be by spray or brush, and then revert to a gel-like paste, forming a firmly adhering, coherent film. The mixtures may be used with solvents consisting of liquid glycerides of naturally occurring carboxylic acids with from 2 to 6 C atoms. Spraying may be effected from an aerosol container or by a two-component nozzle using compressed gases such as air, nitrogen, carbon dioxide, nitrous oxide, propane, butane, fluorinated hydrocarbons as propellents. The mixtures may contain digestive additives such as proteins, e.g. papain, ficin and bromelin; carbohydrates, e.g. monosaccharides such as glucose, galactose and ribose; and natural aromatising agents and flavourings such as extracts and distillates from natural herbs and spices, and salts of glutamic acid and ribonucleic acids. Pieces of meat such as rump steak, pork cutlet, veal steak, whole chicken coated with the mixture may be fried without the use of further fat. Pieces of coated meat may be partly cooked and stored under deep freeze conditions.

Title: Correction of photographic dye-color transparencies
IPC: G03C7/18
Filed: 1930-08-14
Abstract: 367,401. Photographic dye - transparencies ; composite photographs. POMEROY, R. J., 1626, North Crescent Heights, Los Angeles, and PARAMOUNT PUBLIX CORPORATION, Paramount Building, The Times Square, New York, both in U.S.A. Aug. 14, 1930, No. 24403. [Class 98 (ii).] The transparency of a photographic dye image to light of its own colour is rendered uniform, if for any reason such uniformity does not exist, by superimposing in register with it a relatively negative transparent dyeimage of the same subject, of a colour different from the colour of the transparency, or of neutral grey tint. Preferably the colour of the negative image is intermediate between the colour of the transparency and its complementary colour, and is such as will not impair the opacity of the transparency image to light of the complementary colour. The invention is described in connection with a method of producing composite photographs wherein the image of an object 11, illuminated say with blue light by a lamp 18, and situated in front of a plain background 16 of the complementary colour red illuminated by a red lamp 17, is projected by a lens 10 upon a blue transparency positive 12 of the background against which it is desired that the object 11 shall appear in the photograph. This positive may be a dyed bichromated gelatin relief, and, being uniformly transparent to blue light, will not obstruct the rays forming the blue image of the object 11 ; but the red light from those parts of the background 16 which are not shielded by the object 11 will be absorbed by the corresponding image parts of the blue transparency 12. A blue image of the object 11 surrounded by a red image of the background on the positive 12 may therefore be projected on a sensitive film 15 by a lens 14 to produce the composite photograph, an auxiliary collecting lens 13 being placed behind the transparency positive 12. If this positive 12 is not uniformly transparent to blue light, the parts on which the blue image of the object 11 falls may superimpose on this image an image of the corresponding parts of the background. To avoid this, a yellow transparency negative 19 of the same background is registered with the positive 12, the dyeing of the negative being adjusted to render the combination uniformly transparent to blue light without impairing the action of the transparency positive on the red light from the background 16. The negative 19 may alternatively be coloured light pink, or neutral grey.

Title: Improvements in electric soldering apparatus for soldering thin steel bands such as band saws and the like
IPC: B23K3/03

Abstract: 208,204. Kapp, R. Sept. 8, 1922. Soldering.-An electric soldering-apparatus for soldering together the ends of thin steel bands such as band-saws &c. and wherein the bands are held between jaws connected to a supply of current while the ends of the bands are pressed together by a clamping device, has the current supplying the jaws carried by a vertically disposed frame in which transformers are mounted. The transformer which is connected to the usual alternating current mains, comprises primary and secondary coils B, C, Fig. 1, respectively, the latter of which supplies current through arms 1, 1<1>, to holding clamps 2, 2<1>, which are movable, exchangeable and reversible, and are preferably formed of good conducting material such as copper. The transformer may be of box form, as in Fig. 4. Resistances are arranged in the circuit to suit different thicknesses of work. Solder, such as silver or brass solder in sheet form, is placed in the joint and when melted with a flux in the form of a stick is compressed by a clamp comprising levers 10, 12, pivoted together at 13, and to a support at 11, the lever 12 resting on an adjustable support 14 so that the two jaws may meet in the plane of the joint. Other forms of clamps which achieve this object are described, and also one form in which the jaws are adapted to be moved laterally clear of the joint. In another form, spring pressed rollers are adapted to traverse the joint. When using clamps with iron jaws, the joint is retempered by switching on the current with a resistance D, Fig. 1, or one or more of the windings B in circuit. Hardening of the joint may also be avoided by using clamps of non-conducting fireproof material, such as chamotte, porcelain &c.
