Title: Improvements in or relating to aerial photography
IPC: G03B27/68
Filed: 1922-08-01
Abstract: 207,842. MacLeod, M. N. Aug. 1, 1922. Photographic surveying - instruments. -In the production of maps from aerial photographs the height and the angle of tilt of the camera are determined by viewing the photograph or an enlargement thereof through an intervening screen having plotted map points and adjusting the photograph and sdreen until there is visual alignment through a sighting point of the plotted points with corresponding points on the photograph. In the apparatus described, a transparent screen a, Fig. 2, for the plotted map points is adjustable about axes a<1>, a<2>. The. map points may alternatively be represented by adjustable crroiss-bars i, k, l and these may also be adjustable towards and away from the screen a so as to allow for the contour of the plotted points. The support b for the photograph is adjustable, about axes b<1>, b<2> The sight e and the intersections of the axes a<1>, a<2> and b<1>, b<2> are in alignment. The support b is first adjusted so that the perpendicular from e passes through the centre of the photograph and is equal to the focal length of the camera lens multiplied by the scale of enlargement (if any). The support a is then adjusted to obtain the visual alignment of the plotted points with the corresponding points on the photograph. The perpendicular from e on to the support a is then found by means of sighting cross-hairs and the angle between this perpendicular LP<1>, Fig. 1, and the perpendicular LC on to the photograph f gives the angle of tilt required. The height LP<2> of the camera from the ground p is given by LP<1> multiplied by the reduced scale of the plotted map points in the screen h. Specifications 154,219 and 157,236 are referred to.

Title: Improvements in the production of laminated sheets
IPC: C08L27/00
Filed: 1945-08-22
Abstract: Sheets consisting of two or three layers of polymerization products united together are made by polymerizing a liquid containing one or more polymerizable liquids having only one CH2=C< group in a flat chamber until it is converted into a material solid at room temperature, removing one of the side walls and using the remaining side wall with its adhering sheet of polymerization product as a lined wall, together with a similar lined wall or an unlined flat wall to form a second chamber, subjecting a second similar polymerizable liquid to polymerization in this chamber and then separating the polymerized material from the chamber.  The side walls of the chambers are rigid but capable of relative movement. Specified polymerizable liquids are styrene, methyl methacrylate and vinyl acetate.  Preferably, the liquids also contain dissolved polymeric materials, e.g. polymethyl methacrylate, and may also contain plasticisers, dyes, pigments and polymerisation catalysts and inhibitors.  Preferably the inner surface of one side wall of the chamber is coated with a layer of separating agent, e.g. a detergent or a surface-active substance, and the polymerizable material is polymerized only until it has just solidified and adheres to the other side of this chamber.  The polymerization is carried to completion in the second chamber.  In an example a laminated sheet having veneers of black and white material is made from a mixture of methyl methacrylate, polymethyl methacrylate and dibutyl phthalate suitably dyed and pigmented using a methanol solution of cetyl trimethyl ammonium bromide as separating agent. Specification 450,305 is referred to.

Abstract: 1,191,806. Reactors. UNITED STATES ATOMIC ENERGY COMMISSION. 28 April, 1969 [3 June, 1968], No. 21542/69. Heading G6C. In a molten-salt-fuelled nuclear breeder reactor, a single salt mixture containing both the fissile and fertile materials flows through the core and the surrounding breeding blanket. The molten salt mixture passes from the plenum 8, upwards through the core formed of hollow graphite rods, 10, which float in the salt, and are urged upwards against the grid, 11. A minor portion of the mixture passes radially outwards and flows upwards through the blanket, 16, containing graphite spheres, 15. The latter pack together and exert a lateral inwards retaining force against the rods, 10. Thermal neutrons are absorbed by the fissile material in the core while, in the blanket, 16, as the percentage of salt mixture is higher than in the core, the thermal neutron flux is less in it is hardened and absorption of neutrons by the fertile material is greater than in the core to effect breeding. Neutron leakage is reduced as the multiplication constant, effective, of the blanket region is less than one. In an alternate form, vertical graphite tubes are used in place of spheres, 15. Additionally, the blanket graphite may be made less dense. than that in the core and the same volume fraction of salt mixture used in both the core and blanket.

Abstract: 777,097. Making electric resistances. GENERAL ELECTRIC CO. July 26, 1955 [July 26, 1954], No. 21606/55. Class 83 (2). [Also in Group XI] An electric heating element of the tubular metal sheathed type may have one or more resistance conductors of a nickel-chromium alloy, and a sheath of copper, brass, aluminium or a nickel chromium-iron alloy, the electrically-insulating medium surrounding the conductors being textile filaments of silica or siliceous material. The conductors may be circular, flat, rectangular or square in crosssection, and the sheath may be circular, oval, triangular, square or " 8 " in section. Insulation 32, Fig. 2, comprises filaments, preferably in yarn or thread form, braided into a tubular jacket or formed into a wrapping of tape. The filaments may comprise a glass fibre from which a preponderance of the glass-forming metaloxide constituents have been leached with a mineral acid (preferably HCl or HNO 3 ). In making an element of normal length, the insulation 32 is applied to the resistance conductor 31, the whole being placed in a preformed sheath 33 which is then cold-rolled or swaged to reduce its cross-sectional area. The ends of the element are sealed by porcelain or glass plugs in which steel terminals, secured on the conductor 31, may be embedded. For forming an element in a continuous long length, Fig. 10, conductor 31 is fed from a roll 41 to a braiding or wrapping head 42 where silica filaments are supplied in the form of threads or tapes, the insulated conductor then being sheathed by metal stock 33a which is formed, seam-welded and compressed at 47-49, the finished element being stored in a continuous length on a roll 50. Fig. 11 shows the stages in forming the metal stock 33a into a tubular sheath for the insulated resistance 31. In Fig. 17, five pairs of compressing rolls are used to progressively reduce the diameter of the sheath 33 and thus compress the insulation about the resistance. If a lubricant, e.g. wax or the like is applied to the silica filaments to ensure proper operation of the braiding or wrapping head, the lubricant is removed, e.g. by burning, before application of the sheath 33.
