Title: Improvements in Electrodes for Storage Batteries.
Inventor: SAVILLE ROBERT
IPC: H01M4/76
Filed: 1916-10-11
Abstract: 112,476. Saville, R. Oct. 11, 1916. Electrodes.-An electrode for a storage battery containing an alkaline electrolyte consists of a number of tubular elements attached to a grid or frame, each element comprising two concentric perforated steel or iron tubes which may be nickelled and between which is the active material consisting of nickel or iron or their compounds. As shown in Fig. 2, the space between the tubes is closed by cup rings 4 and the ends of the outer tube are clinched together at 5 forming means for connecting the elements to the grid. The electrolyte reaches the active material through openings 6 in the tube 1. In the modification shown in Fig. 4, the tubes are closed by a head 7 carrying a projection 9 for attachment to the grid. The electrolyte reaches the active material through a passage 11 and an opening 12 in the projection 9.

Abstract: 1,259,971. Phase holograms. WESTERN ELECTRIC CO. Inc. March 20, 1969 [March 29, 1968], No.14582/69. Heading G2J. Phase holograms are made using a gelatine film sensitized to effect a change in refractive index upon exposure. The gelatine may be hardened before exposure, or after exposure but before the washing step. The film may be sensitized by contacting with a 0À1 to 10 wt per cent dichromate solution for 3 to 5 minutes. After exposure the film is washed with water and dried with a water absorbing solvent. A hologram may be made to record a first set of information are after desensitizing illuminated with a second information carrying beam to produce Moire fringes which can be detected. A phase hologram of the present type may be used as a diffraction grating.

Title: Ozone generators
IPC: C01B13/11
Filed: 1975-04-09
Abstract: 1500443 Ozone generator MARTIN MARIETTA CORP 9 April 1975 [22 April 1974] 14641/75 Heading H5H An ozone generator comprises a corona discharge reaction chamber 12 to which gaseous oxygen is introduced via inlet 14, means, e.g. liquid oxygen 30, to maintain the temperature of the chamber 12 below the boiling point of ozone, an outlet 22 from the chamber 12 containing a liquid ozone trap 32 for blocking the flow of unreacted oxygen through the outlet 22 the trap including explosion suppression means capable of segregating said liquid ozone into volumes of controlled size in order to suppress the explosive decomposition of ozone. The outlet 22 from the annular reaction chamber 12 is filled with glass beads 32 which regulate the flow of liquid ozone from the reaction chamber 12. The beads 32 also prevent too rapid a movement of ozone and thus aid in suppressing explosive decomposition and propagation of the ozone. A sintered glass plug 34 closes the outlet 22 and permits vapourized ozone to issue therefrom. The trap 32 also prevents gaseous ozone from seeping'back into the reaction chamber and mixing with gaseous oxygen. The generator has a thermal insulation jacket 40 of fibre glass. However, the outlet 22 has an exposed uninsulated neck 39 which is so dimensioned that the ozone liquid vapourizes gradually towards the plug 34. The reduced size of the outlet compared with the chamber 12 reduces the risk of rapid vapourization and consequential detonation of the ozone. Should oxygen be fed to the reaction chamber at a rate exceeding the reaction capacity it can escape through the liquid ozone trap. A manometer and a flow rate detector may be provided in the oxygen supply line so that by controlling the output of a step-up transformer supplying the corona discharge reaction chamber 12 and the flow rate of oxygen, the reaction rate may be controlled. The reaction chamber is formed by a tubular aluminium wall 16 sealed with P.T.F.E. tape 21 coated with sealant to a glass dielectric tube 18. An aluminium foil outer electrode 26 is wrapped about the glass tube 18 and secured in place by tinned copper wire. Copper leads 25, 27 connect electrodes 16, 26 to the transformer. The hemispherical bottom of the aluminium wall 16 is. closed by a welded plug 41 to provide a container for coolant 30.

The outside frame 12 of carrier 9 has gusset plates 13 on which the other end of member 10 is tightly held by strap 17. One end of member 10 is thus displaceable and the other rigid. Stop members may be provided to limit the displacement.

Double-sided mosaics are made by a process involving two photo-engraving steps. A base support of metal sheet, e.g. aluminium or a glass plate coated with layers of evaporated aluminium and zinc is coated with photoengraving emulsion by dipping and is exposed through an apertured template. The plate is developed, unexposed emulsion removed by washing, and the uncovered portions electroplated, e.g. with copper. The exposed emulsion is wholly removed and the sheet recoated with photographic emulsion. It is then exposed through a photographic plate having opaque areas corresponding to, but of smaller size than, the plated areas. The unexposed emulsion in the centre of the copper-plated areas is washed away, the plate immersed in a plating bath, e.g. copper cyanide so as to build up metal plugs in the apertures, and the aluminium or other backing removed in a bath, e.g. of potassium hydroxide. The electroplating steps may be replaced by spraying.. A photographic positive of the finished mosaic may be used to combine the two photographic steps.
