Abstract: 1,206,692. Film strip projectors. HUGHES AIRCRAFT CO. Feb.15, 1968 [March 27, 1967], No.7562/68. Heading G2A. [Also in Division G1] A control system for a display device 138 for indicator symbols (12, 16), (18), having variable positions representing respective indications (e.g. a route RS1 and a lateral deviation VD1 therefrom) comprises means controlling cams 92, 94 whose surfaces are movable in a predetermined positional relationship and arranged to move symbol-forming slides 170, 172 in a slot in the device 138 to produce the indications. The system includes a differential gear 100, Fig.7 which can rotate the cams 92, 94 jointly about an axis through the centre of a display surface. The cam surfaces are so curved relative to the axis that the symbols move outwards from the centre (where their lines coincide) to one side or the other, the rate of movement of the deviation symbol being a predetermined multiple (say 5) of that of the route symbol. A gear 96 is mounted jointly to both cams 92, 94, a gear 98 is mounted on the device 138 in which the cams are rotatable'and the differential gear 100 can drive selectively the gear 96 alone to move the symbols without changing their orientation or both gears 96, 98 to rotate the device 138 and the cams, thus reorienting the symbols without moving them laterally as the cams do not move relative to the device 138. The control system is disclosed in a navigational aid system (see Specification 1,206,691). (For Figures see next page)

Title: Improvements in or relating to the production of three-colour photographic images
IPC: G03C7/26
Filed: 1944-05-02
Abstract: 572,464. Colour photography ; toning. COOTE, J. H. May 2, 1944, No. 8274. Addition to 553,377. [Class 98 (ii)] Relates to that form of the tricolour process described in the parent Specification in which (1) a silver-halide emulsion layer supercoated with a hydrophilic colloid such as gelatin, and containing a fugitive yellow dye, is printed through its film base from the green-record negative, developed, and the silver of the image is converted to silver and nickel ferrocyanides ; (2) the layer is printed through the supercoat from the blue-record negative, developed in a bath which is loaded to prevent its penetrating to the ferrocyanide image, and the developed silver is converted to a yellow dye image mordanted on silver iodide; (3) the ferrocyanide image is toned magenta with an alkaline solution of dimethylglyoxime ; and (4) the supercoat is treated with a cyanotype sensitizer, printed from the red-record negative, and developed blue-green. According to the present invention, the use of a loaded developer in step (2) is avoided by redeveloping the ferrocyanide image produced in step (1) and removing the silver so developed as with an acid oxidising bath before going on to step (2). With this procedure, it is immaterial whether step (3) is performed before or after step (2). The silver removal bath may contain potassium permanganate and sulphuric acid, and be followed by a clearing bath of alkali bisulphite. The invention further consists in minimizing swelling of the gelatin of the emulsion layer in step (3) by adding to the alkaline dimethylglyoxime bath a water-miscible alcohol such as methanol, propanol, ethanol, or isopropanol.

Abstract: Stable, clear polymethylolphenol solutions are prepared by heating at 60-100 DEG C. and at a pH of 7.0-9.5, 4-10 mols. of monomeric formaldehyde as a 58-65 per cent. aqueous solution with 1 mol. of phenol containing not more than 20 per cent. of water until the free formaldehyde content of the mixture is below 35 per cent. and cooling the solution to below 30 DEG C.  The formaldehyde is kept monomeric by maintaining it at 80 DEG C. from the time of its preparation until the time of its use.  A number of examples are given and are compared with results achieved with different conditions.  The pH of the cooled solution may be adjusted to 4.5-6.8 for greater stability. The solutions may be made more viscous by heating them at 70-100 DEG C. at a pH of 7.0-9.5.  Urea, phenol or other similar resin-forming ingredients (a list is given) may be added before or after bodying. The products may be thermoset by heating at 120-175 DEG C.  Examples are given of the use of the solutions, with the addition of urea and phenol, as adhesives for plywood.  The adhesive solutions before thermosetting may be mixed with walnut shell flour and ammonium chloride as a hardening catalyst.  The products may also be set in the cold.  The solutions are stated to be useful for many other purposes for which resin-forming solutions are conventionally employed.  Specification 641,703 is referred to.ALSO:Stable, clear polymethylol phenol solutions are prepared by heating, at 60-100 DEG C. and at a pH of 7.0-9.5, 4-10 mols. of monomeric aqueous formaldehyde of 58-65 per cent strength with 1 mol. of phenol containing not more than 20 per cent water, until the free formaldehyde content of the mixture is below 35 per cent and cooling the solution to below 30 DEG  C.
