Title: Improvements in photographic processes and in photographic sensitive materials therefor
IPC: C07D231/08
Filed: 1963-08-30
Abstract: 1,055,144. Photographic silver halide material and process. KODAK Ltd. Aug. 30, 1963 [Sept. 4, 1962], No. 34362/63. Addition to 930, 572. Heading G2C. A photographic light-sensitive silver halide material comprises a support carrying at least one sensitive silver halide emulsion layer and, in the same or an adjacent layer, an alkaline substance and at least 5 grams of a 3-pyrazolidone developing agent per mole of silver halide in the layer, the silver halide grains being an average diameter of 1À5 microns or less and the emulsion satisfying an exposure and development test described in the Specification. A large number of emulsions in which the silver halide is predominantly silver bromide and which contain no gold or sulphur sensitizers are stated to satisfy the test. The 3-pyrazolidone developing agents may be those described in the parent Specification or in Specification 1, 023, 701 and the exposed material may be processed by heating as described in the parent Specification e.g. by heated rollers, steam or hot moist air. During processing substantially all the silver halide is converted to silver, black filamentary silver being formed in exposed areas and hexagonal crystals of silver giving a green to brown colour in unexposed areas, the image being stable to light due to the absence of silver halide. If heterocyclic or aromatic mercaptans such as mercaptotetrazoles, mercaptobenzoxazoles, mercaptobenzothiazoles or toluene thiols, e. g. 1 -phenyl-5-mercaptotetrazole and, optionally, sodium thiosulphate are added, a positive image is obtained. The addition of sodium thiosulphate, yellow colloidal silver, zinc sulphide, reduced silver, α-picolinium-#-phenylethyl bromide or dodecyl-pyridinium-p-toluene sulphonate increases the rate of image stabilization. The emulsions may also contain sucrose, sodium metaborate, sodium sulphite, potassium bromide and ascorbic acid.

Title: Improvements in or relating to electric storage and data routing apparatus
Inventor: LUCAS JOHN HAROLD
IPC: G11C11/28
Filed: 1956-11-09
Abstract: 811,242. Electric distributers. POWERSSAMAS ACCOUNTING MACHINES Ltd. Oct. 14, 1957 [Nov. 9, 1956], No. 34413/56. Class 40 (3). [Also in Group XIX] An electric storage and data routing apparatus comprises cold-cathode gas-filled triodes, Fig. 1, arranged in columns and rows, a cathode load L1-Ln for each column, a column conditioning switch operable to condition the columns of triodes for triggering, a rectifier R1-Rn for each column connected with the corresponding load and with the switch, a selectively operable triode-triggering device 6, Fig. 2, having for each row a common connection T1- Tm to all trigger electrodes and operable to trigger conditioned triodes of the row, and a pulse train generator 9 having for each row (except possibly one row) a common connection P2-Pm. to all anodes and operable to apply pulse trains to the anodes for transmission through triggered triodes and development as output pulse trains across the cathode loads. The apparatus described translates characters sensed from a record card in device 5 into printer - actuating coded pulse trains, the columns of the triode matrix corresponding to the columns of the card, and the rows corresponding to different characters. The card is sensed column by column, and a column counter 3 applies triggering potentials successively to lines G1-Gn. leading to triodes C1- Cn, Fig. 1, of the column conditioning switch 2. When a triode C1-Cn is triggered, the reduced anode potential blocks the associated rectifier R1-Rn and thus enables the triodes in the associated column of the matrix 1 to respond to triggering potentials on lines T1-Tm. One of these lines is marked by decoder 6 corresponding to the character in the card column being sensed. Line T1 is marked if no character is sensed from the card; this line and the associated matrix row may be omitted. Once a triode in a matrix column has been triggered the potential of the common cathode connection rises sufficiently to prevent any other triode being triggered in that column. Thus, when the sensing of a card has been completed, in each column of the matrix one and only one triode will be conducting to represent the character (or no character) sensed from the corresponding column of the card. During a subsequent time period, a timing switch 8 passes pulse trains from generator 9 to lines P2-Pm, and these pulses are routed through the conducting triodes to output lines S1-Sn leading to styli of a high-speed electric stylus printer, e.g. as described in Specification 707,736, [Group XV], each pulse train causing a stylus to trace out a corresponding character on a moving web. After the printing operation, the matrix and column conditioning switch are reset by switching off supply voltages HT, NV. In a modification, a plugboard is interposed between counter 3 and switch 2, in which case a number of matrix columns may be conditioned to store a character sensed from one card column.

Patent GB-994404-A (GB)
Title: Improvements in and relating to electrodes
IPC: C23F1/00
Filed: 1963-09-06
Abstract: Skeleton catalyst electrodes are formed by vapour depositing the components of an alloy on to an electrically conducting base such as graphite and then dissolving the less noble component of the alloy layer in an acid or alkali to leave the catalytically active metal in a porous form.  The catalysts include the "Reney" (Registered Trade Mark) alloys in which the active metal component may be Ni, Co, Fe, Ag, Pt, Rh, Ir, Ru, Pd and the less noble component which is dissolved out of the alloy may be Al, Sn or Zn.  The alloy may also include Au, V, Mo or Cr to increase the activity of the catalyst. Suitable substrates are graphite discs, fabric or felt, sintered metal, wire mesh and metallized ceramics, plastics, fabrics or felts. The alloying components are vapour deposited, under vacuum, from separate sources either simultaneously or successively.  If deposited successively, the coated substrate is heated in an inert gas or under vacuum to allow alloying of the components.  The base is also heated to e.g. 300  DEG C. prior to the coating process and in one example the evaporation is effected by electron beam.  Electrodes may also be made by vapour depositing the alloy components on powdered material and then condensing a plastic or metal powder on to the powder.
