Patent GB-238862-A (GB)
Title: Improved method of securing accurate colour values in colour printing and colour photography
IPC: G03F3/10
Filed: 1925-07-20
Abstract: 238,862. Blecher, C. July 20, 1925. Colour photography; photo-mechanical printing-surfaces. - A method of securing accurate colour values in the production of photographic colour record negatives for photo-mechanical printing or multi-colour photography consists in producing, on thin films stretched on frames, from one or more negatives of the original, a set of coloured positive images or drawings, each representing one component colour, in superimposing these images &c. upon a white reflecting ground to determine the extent to which the colour rendering is defective, and from the information so obtained either (a) retouching the original colour record negatives and producing copies therefrom, or (b) modifying the colours of the positive images or drawings and producing corrected partial negatives by reproduction therefrom. Printing formes are then produced from the corrected original negatives, or from copies taken from these, or from corrected copies taken from the original negatives. The films are so thin that the colour of the material of the film is not a disturbing factor, and they are united to their reinforcing frames by adhesive, such as nitrocellulose or gelatin. When a set of colour record negatives is available, copies of them in colour are made on separate thin films sensitized in any manner. These copies may be coloured reliefs, or toned silver images. If a black component is used it is preferably in untoned silver. To facilitate superimposition the copies are made on films of different sizes, the frames of which fit one within another. The lowermost image may be produced on opal glass, white paper, or white celluloid, which itself forms the reflecting ground when the images are superimposed. When the method of modifying the colours of the positive images is used, these images are made with short gradation, so that any corrections necessary will be by way of intensification. If a set of colour record negatives is to be produced from a single half-tone negative, a copy of the negative is made, upon a thin film or on a white support, to represent one component colour. The remaining components are drawn in colour on thin blank films superimposed on the first copy. Alternatively, all the components are produced by selectively colouring copies of the negative on thin films. When the components have been coloured to the required degree, as determined by superimposition, they are placed on white supports and copied to produce half-tone or screen negatives of the required sizes.

Title: Smoke detector and signal for airplanes
IPC: A62C3/08
Filed: 1947-07-14
Abstract: 639,332. Smoke detecting. C-O-TWO FIRE EQUIPMENT CO. July 14, 1947, No. 18712. Convention date, July 13, 1945. [Class 40 (iii)] Smoke is detected in a moving vehicle (Fig. 11) by connecting various compartments in the vehicle by a tube 73 to a smoke detector which is itself connected to the outside of the vehicle by tube 80 so that smoke is caused to circulate through the detector by the movement of the vehicle. The construction and circuits of the detector are shown in Figs. 1 and 5. A normally unilluminated photo-cell is energized by light reflected from the smoke particles, and a further cell normally energized by light from the source has its illumination decreased by the presence of the smoke. These two cells are connected in a differential circuit with a moving coil relay so that an alarm is operated. As shown, light from a source 6 is focused to a parallel beam by a lens system 38 and passes through a smoke chamber 4. At the side of the beam and inclined at an angle to it is a current generating photo-cell 10. A further photo-cell 19 is mounted with its light-sensitive surface facing away from the light source on the end wall 21. Light passes through an aperture in this end wall and is reflected on to the active surface of the photo-cell through another aperture 22 by a reflector 23. A mask carried by a nut which runs on a rotatable screw 28 permits of adjustment of the light reaching photo-cell 19 and initial balancing of the system. The moving coil relay 13 is mounted on the side of the smoke chamber, its pointer being visible through a window in the side of the chamber. The circuit is shown in Fig. 5, the coil of the relay 59 being connected across the junction of opposing cells 10 and 19. The presence of smoke also causes operation of this relay and a further power relay 57a closing the circuit to a warning lamp 16 and an audible alarm 18 through contacts of a double-pole switch 54. A normally energized relay 56a maintains a " trouble " lamp 55 normally lit. A reset button 50 causes resetting of the pointer of the moving coil relay by an electromagnet 47 operating a plunger 41. All the relays and photo-cells are contained in the unit 1 which may be mounted in any compartment and connected to an instrument panel containing the reset switch by a plug and socket 61. Smoke enters the compartment at inlet 7 and leaves through outlet 8.
