IPC: G03C7/14
Abstract: 462,655. Colour photography. BLONDEL, A. June 11, 1935, Nos. 16866, 16867, and 16868. Convention dates, June 11, 1934, Nov. 12, 1934, and May 15, 1935. [Classes 97 (i) and 98 (ii)] Apparatus for the projection or projectioncopying of images on lenticular films comprises an optical projection or copying system, a colour filter (for projection), at least one diaphragm for delimiting the light rays, a condenser lens near the lenticular film for producing, at the centre of the filter in projection or the diaphragm in projection - copying, an image of the centre of a light emitting surface, and at least one thin correcting lens for bringing into the plane of the filter or diaphragm the points of convergence of the axes of the elementary light beams emanating from the lenticulations of the film. As shown in Fig. 1, the film f is projected on to the screen E by an optical system 02 and a colour filter F2. The source of light A is provided with a condenser C, and a lens L0 produces an image of the source of light A on the filter F2. A correcting lens L1 may be employed near the lenticular surface of the film. As shown in Fig. 2, the original film f is projected on to the copy film f2 by optical systems O1, 02, the lenticulations of the films facing. The plane of the virtual image of the view-taking filter is brought into the plane of symmetry of the optical systems 01, 02 by a very thin convergent or divergent spherical or cylindrical lens L1. This correction may be previously effected by the use of a correcting lens in taking. The position of the filter to be used in projection may be corrected during copying by the use of the thin lens L2. Opaque or tinted screens may be placed in the diaphragm to control the rays corresponding to particular filter bands. Modifications are described in which a third lens is used on the side of the original lenticular film opposite to the lens L1 to compensate for the disturbance introduced by the lens 4 on the concentration of the light. A diaphragm is provided near the light source, and the lenticulations of the original film may face in either direction. The light source may comprise an internally whitened chamber containing several lamps and provided with a diffusing window, which may be water-cooled. A single arc may be used in the chamber. A filter coloured progressively from the edges towards the centre may be placed in front of the window. The periphery of the colour filter or the diaphragm for a maximum useful area is determined experimentally by a stenopeic method employing a screen of size equal to that of a film frame and provided with a number of holes. In copying, the diaphragm may be provided with three windows. Slots may be moved in front of the objective and light-source diaphragms during copying.

Abstract: 1248572 Heating fluids electrically LAPORTE TITANIUM Ltd 4 Oct 1968 [11 Oct 1967] 46500/67 Heading F4 AN2A A fluid heater comprises one or more metal tubes 1 provided internally with metal fins or similar members 13 arranged to increase the area of contact with the fluid and being in contact with the tube wall, and the configuration of the tube and fins is such that the cross-sectional area of the flow path of the heating current therethrough increases in the direction of flow of the fluid through the heater. Each fin assembly 12 comprises eight fins 13 constructed in four pairs by longitudinal bending of strips 15, Fig. 4 (not shown), and welded at intervals to short tubular spacers 14. Each tube 1 has a second fin assembly 21 immediately downstream of its electrical connector 11 (which connector is water-cooled), to give an initial large cross-sectional area of flow path for current before it decreases suddenly to its minimum value, i.e. the area of tube wall alone, and then increases in a stepwise manner along the fin assembly 12. Heated fluid flows through inlet manifolds 9, one at each end of the heater, along the heated tubes 1 to a transversely extending common outlet conduit 3. The outlet conduit 3 and supply manifolds 9 are eathed in operation, and D.C. is supplied to the connectors 11. The tubes I are of a platinum/rhodium alloy, as is conduit 3, but the fin assemblies 12, 21 are preferably platinum. Tubes 1 are alternatively platinum/ruthenium or platinum/iridium. The fins have indents 20, Fig. 4 (not shown) at intervals to reduce thermal stresses resulting from differential expansion between the fins and the tube wall. The heater is in a thermally insulating enclosure 2 of refractory material to which heat is supplied, other than by radiation from the tubes, to reduce heat losses from the tubes. The heater is used in the manufacture of titanium dioxide by the vapour-phase oxidation of titanium tetrachloride, using the process and other apparatus of Specification 1171113, or for heating of the halides of silicon, aluminium or zirconium (excluding fluorides).

Abstract: 1526291 Primary cell containing compressible spacer MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 26 Nov 1975 [4 Dec 1974] 48508/75 Heading H1B A primary cell has a cathode and an anode with an interposed separator, an enclosure which serves as one terminal and a metal top closure insulated therefrom which serves as the other terminal, the cathode and anode each being electrically connected to one or other terminal, and between the cathode and/or anode and its/their respective terminal there is a spacer which is chemically stable in the cell, electrically conductive, capable of holding electrolyte and of reducing its apparent volume under pressure. The spacer may be a spongelike porous metal body, e.g. a sintered body, of stainless steel, Ni, Ti, Cu, Al, Fe, Ag or alloy, of 80-95% porosity and pore diameter <500 Á, or a C or metal fibre body. As shown, a cell has Li anode 4, non-woven polypropylene separator 3, fluorinated C/C powder cathode 1 in stainless steel ring 2, an enclosure 5 of stainless steel and a top closure 7 embedded in polypropylene sealant/insulant 6; 9 is a porous Ni sheet of 90% porosity and pore diameter 100 Á. Bodies 9, 1 and 3 are all impregnated with electrolyte, e.g. a perchlorate, AlCl 3  or LiBF 4  in propylene carbonate, dimethoxyethane, dioxolane, CH 3 CN, THF, DMSO, ethylene carbonate or γ-butyrolactone. In another embodiment, a further compressible spacer, of C fibre, is positioned, in addition, between cathode 1 and enclosure 5. In other embodiments, (1) a central C rod in a depolarizer surrounded by a separator is surrounded by a Li cylinder; a sponge Ni spacer is placed between the Li and the outer cylindrical metal can and (2) a cell has a plurality of successive concentric cylindrical cathodes, depolarizers and anodes; again a porous spacer lines the outer container. In use, as the cathode swells, its expansion is taken up by the compressible spacer, from which electrolyte is simultaneously expelled; thus the cell continues to function without build-up of pressure. Other cell systems mentioned are Agchromate-Li, MnO 2 -Li, CuO-Li, MnO 2 -Zn, HgO-Zn, and AgO-Zn.
