Title: Photosensor driving system
IPC: H04N5/335
Filed: 1973-01-26
Abstract: 1425421 Photo-sensitive storage systems HITACHI Ltd 26 Jan 1973 [31 Jan 1972 8 March 1972] 4088/73 Heading G4 [Also in Divisions H3 and H4] In a photo-sensor storage system comprising an array of photo-sensitive elements, e.g. phototransistors, the outputs of which are connected to a common load resistance, sampling pulses are applied sequentially to the elements after an electric charge storing time charge on the, elements being erased by forcibly reducing to zero the voltage on the output lines. This permits scanning to be affected more quickly than in systems where the charge is stored on the base emitter and base collector capacitances of photo-transistors during a charge interval, any charge on the base collector capacitance being discharged during a subsequent sampling pulse interval. The system may be used in an optical character reader (Fig. 5, not shown) in which characters on a sheet (5) are read using light fibres (2, 3) directing light to an array of photosensors (6), the read character pattern being stored in a memory 9, identified by a discriminator 10 and displayed or printed. As described a start pulse from the generator 14 (Fig. 6) is fed to a charge erasing time setting circuit 20 which controls the length (TH, Fig. 4, not shown) of the erasing pulse. After the erasure time the circuit triggers a charge storage time setting circuit which controls the length (TI) of the charge storing pulse and subsequently triggers a gate circuit 40 to allow pulses from generator 80 to pass via a pulse width setting circuit 50 to a decimal counter chain 60, 70, the outputs AX1-AX10, BX1-BX10 of which are decoded to provide a hundred sequential pulses to sample the photo-sensitive elements.

Title: Methods of treating epoxy surfaces
IPC: C08J7/14
Filed: 1972-02-01
Abstract: 1384113 Treating epoxy coatings WESTERN ELECTRIC CO INC 1 Feb 1972 [11 Aug 1971 20 Aug 1971] 4707/72 Heading B2E [Also in Divisions C3 and C7] A surface comprising a cured composition comprising bis-phenol A-epichlorohydrin epoxy is treated to improve the adherence of materials by (1) exposing the surface to a swellant so as to swell the surface, the swellant being selected from methyl ethyl ketone, tetrahydrofuran, dioxane, pyridine, dimethylformamide, a mixture of a) methyl ethyl ketone b) methanol and c) ethanol or a mixture thereof and (2) exposing the swelled surface to an etchant comprising H 2 SO 4  or Cr VI ions or H 3 PO 4  or a mixture thereof so as to etch the surface. The bis phenol A-epichlorohydrin epoxy may be brominated. The curing agent may be dicyandiamide. After the swelling treatment the epoxy surface may be either washed in a solvent or air-dried so as to remove the excess swellant from the surface thereof prior to etching. A preferred etchant comprises an aqueous solution of sulphuric acid, and CrO 3 . The etchant may also comprise a surfactant, e.g. a perfluorinated sulphonate. All traces of a deposit on the etched surface may be removed by rinsing with water and treating with a reducing agent for Cr VI ions such as Na 2 SO 3  or alternatively with a basic agent, e.g. NaOH. Materials for deposition on the etched surface may comprise aqueous or organic based paints, lacquers, inks and adhesives, aqueous or non- aqueous solutions of inorganic salts, aqueous or non-aqueous electroless metal deposition solutions, metals applied, e.g. by dipping, brushing, spray-coating, spin-coating, vapour deposition, electroless deposition with or without electrodeposition, sputtering. The product may then be baked, preferably at 110-160C for 10-60 minutes. Where an electroless technique is employed, the etched surface is sensitised by depositing or absorbing on the etched surface a sensitiser, e.g. Sn ions, then activated by depositing a catalytic metal, e.g. Pd over the etched surface and then immersed in a standard electroless plating bath, e.g. containing Cu ions. In a preferred embodiment, the etched surface is coated with a photo promoter solution which may be either a positive or a negative type, the photo promoter coated surface selectively exposed to a suitable mass to a source of radiation so that selective regions are formed which are capable of reducing a metal salt, e.g. PdCl 2 , these regions are exposed to the metal salt and the precious metal positive region then exposed to a suitable electroless metal plating bath. In a typical Example a steel plate is coated in a fluidized bed with an epoxy resin mixture obtained by interacting bisphenol A with epichlorohydrin and the coating cured. The coated plate is 1) immersed in methyl ethyl ketone, rinsed with water and 2) etched in a solution of CrO 3 , H 3 PO 4  and H 2 SO 4 , 3) immersed in a sensitizing solution comprising SnCl 4  and SnCl 2  . 2H 2 O, 4) immersed in aqueous PdCl 2  solution, 5) then immersed in an electroless copper plating bath.

Patent GB-734707-A (GB)
Title: Removing mercaptans from hydrocarbon fractions
IPC: C10G29/06
Filed: 1953-02-20
Abstract: A mercaptan-containing hydrocarbon fraction is purified by contacting it with copper hydroxide, basic copper carbonate or a copper salt of an organic acid containing more than five carbon atoms per molecule so that the mercaptans form a complex with the copper compound, and then distilling the hydrocarbon fraction so that the complex is removed.  Hydrocarbon fractions mentioned are naphtha, gasoline, white spirit, kerosene and light and heavy gas oils, while a suitable copper salt of an organic acid is copper naphthenate.  Thus, copper naphthenate may be dissolved in the hydrocarbon fraction or added to the hydrocarbon fraction as a solution in hydrocarbons.  If the copper compound employed is solid and insoluble in hydrocarbons, the hydrocarbon fraction may be shaken with the copper compound, surplus copper compound being subsequently removed if desired, for example by decantation. Alternatively, the hydrocarbon fraction can be filtered through a layer of the copper compound.  It is also possible to pass the hydrocarbon fraction, together with an aqueous solution of the copper compound, through a mixer and then to separate the two phases, for example in a settling tank.  The hydrocarbon fraction may be further refined, for example with 96-98 per cent of fuming sulphuric acid, before or after the treatment with the copper compounds and this further refining may be followed by distillation.  In the examples: (1) gasoline is treated with sulphuric acid, neutralized with soda lye, rinsed with water, contacted with basic copper carbonate and distilled off from the resulting complexes, and (2) copper naphthenate gasoline, which is then distilled off from the resulting complexes and finally treated with fuming sulphuric acid. Specification 700,165 is referred to.
