Patent GB-425986-A (GB)
Title: Improvement in process of oil-proofing material and product therefor
IPC: D21H19/12
Filed: 1933-09-20
Abstract: Fibrous material such as fabric, paper, for example in the form of containers, or the braided covering of wires, is rendered oil-proof by coating one surface with an aqueous solution of a soap having as base triethanolamine or a monovalent metal such as sodium or potassium, which may contain a plasticizer such as ethylene glycol, glycerine, dextrine, or casein, solubilized for example with triethanolamine.  Vegetable oils such as cotton seed, rapeseed, linseed, soya bean, olive, peanut, sesame and castor oil, their fatty acids and also sulphonated derivatives or resin or shellac may be used in making the soap which is dissolved in water to form a concentrated solution.  Alcohol may be added to prevent foaming and gelling.  In examples (1) shellac soap made by boiling shellac with borax solution is mixed with casein solubilized with ethanolamine and a sulphonated vegetable oil soap.  (2) Casein is dissolved in an aqueous solution of triethanolamine and mixed with a sulphonated vegetable oil soap into which pigments such as calcium and lead carbonates have been ground.  The composition is applied to braided insulated wire. (3) Powdered rosin is saponified with sodium hydroxide and the solution concentrated; sulphonated vegetable oil soap alone or with triethanolamine resinate is then added.  Compound paper may be made by using the oil-proof layer as an adhesive to bind together the laminations.  The Specification as open to inspection under Sect. 91 describes also the use of ammonium soaps.  This subject-matter does not appear in the Specification as accepted.

Patent GB-584358-A (GB)
Title: Improvements in or relating to electrical signalling systems
IPC: H04B3/54
Filed: 1944-12-29
Abstract: 584,358. Signalling over power circuits. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and SAVILLE, W. Dec. 29,1944, No. 26064. [Class 40 (iv)] In a signalling system in which high-frequency signalling currents are superimposed on electric supply mains, a test is made immediately prior to signalling to ascertain whether any currents of signalling frequency are present on the line. Any output from the transformer L1, L2, which is tuned to the signalling frequency, is superimposed on the standing voltage on the grid of a gas-filled valve CCT and, if of sufficient amplitude, causes it to fire and operate relay TR. Contact TR1 renders the signalling master switch MS inoperative for as long as the parasitic currents persist, at the same time actuating an audible or visible alarm over lead 14. Alternatively, the glow of the valve CCT may be used as an indicator. If there are no parasitic currents on the mains when the master switch is first operated, relay MSR operates and locks over MSR1 while MSR2 initiates signalling. Thus, disturbances occurring during signalling have no effect. The master switch MS can be made to open a point in lead 14 to prevent an alarm being given by signalling currents and switching can be incorporated at points 10, 11, 12, 13 to make the equipment responsive to other desired frequencies. A contact voltmeter as described in Specification 580,393 may be substituted for the gas-filled valve.

Title: Process for producing colour photographs
IPC: G03C7/28
Filed: 1938-09-10
Abstract: 520,529. Colour photography. GASPAR, B. Sept. 10, 1938, No. 26510. [Class 98 (ii)] A three-layer taking film having a front bluesensitive layer, a middle yellow-coloured greensensitive layer, and a rear magenta-coloured red-sensitive layer is exposed and developed, the two rear layers processed to coloured images by dye-destruction, and the front silver image converted into a blue-green image, and the bluegreen image and one other image is printed on to one side and the third image on to the other side of a three-layer printing film in which the layers are superimposed on a single support and each contains a dye absorbing one-third of the visible spectrum and transmitting the other twothirds and is sensitized for the light of that third of the spectrum transmitted by the dye and not recorded in the identically coloured layer of the taking film, and the printing film is developed and processed by dye-destruction. The taking film may comprise a front blue-sensitive silver halide emulsion layer containing diphenylguanidine, a middle green-sensitive emulsion containing Chrysophenine G, and a rear redsensitive emulsion containing Benzopurpurine 10B. After exposure the front layer is dyed bluegreen, and the film developed and processed by dye-destruction. The middle layer of the printing film is screened from the blue rays of the printing light by a yellow dye. If the yellowcoloured layer is the layer printed separately from the other two, the middle layer or a filter layer between it and the third layer contains a removable yellow dye such as tartrazine. If the middle layer is the yellow-coloured layer, no additional filter dye need be added to it unless desired. In one example the printing film has a front yellow-dyed (Chrysophenine G) redsensitive layer, a middle blue-green-dyed (Diamine Pure Blue FF) green-sensitized layer, and a rear magenta-dyed (Chlorantine Red 8B) bluesensitive layer, the support being between the middle and rear layers or behind the rear layer. A yellow filter layer is provided between the middle and rear layers or a yellow filter dye is added to the middle layer. The blue- and redcomponent records are successively printed in either order on to the front of the printing film, and the green-component record is printed on to the rear of the printing film. The printing of the records may be effected simultaneously using a beam-splitting device, or the blue- and redrecords may be printed simultaneously using mixed printing light. In another example the film comprises a top magenta-dyed bluesensitive layer, a middle yellow-dyed red-sensitive emulsion, and a rear blue-green green-sensitive layer. The support may be between the middle and rear layers or at the rear. The dyes Chrysophenine G and Chlorantine Red 8B are preferably used in the form of their diphenylguanidine salts. Specification 520,527 is referred to.
