Title: Photoresists and method of making same
IPC: G03C1/72
Filed: 1961-04-05
Abstract: 986,487. Photoresist and printing plates therefrom. HORIZONS Inc. April 5, 1961 [April 19, 1960], No. 12231/61. Headings G2C and G2M. A photoresist composition comprises an amine in which the amine is attached to a carbon atom of a benzene nucleus or a benzyl radical, a five or six membered heterocyclic amine or its N-vinyl derivative, an organic halogen compound which produces free radicals on exposure to light (including ultra-violet radiation) dispersed in a synthetic resin or a mixture of a synthetic resin and a hydrocarbon wax. The resist composition is dissolved in a hydrocarbon solvent, spread on a support, exposed to light and the unexposed portions are dissolved in hydrocarbon solvent leaving the insoluble image. The resist is soluble in ketones and cyclic ethers but insoluble in hydrocarbons and water and is therefore hydrophobic. The exposed image may be heated before removing the unexposed portions, this step being essential if a N-vinyl compound is used. Preferred nitrogen compounds are diphenylamine, benzidine, 4-4<SP>1</SP>- methylene-dlaniline, 1-naphthylamine, tribenzylamine, p-toluidine, diphenylguanidine, indole and N-vinylcarbazole. Other specified compounds are N-vinylpyrrolidone, o-toluidine, N, N-dimethylaniline, dibenzylamine and N-methyldiphenylamine. The organic halogen compound may be carbon tetraiodide, carbon tetrabromide, hexachloroethane and 1, 2, 3,4-tetrachlorotetrahydronaphthalene. Specified hydrocarbon solvents are benzene, toluene, xylene or cyclohexane. A plasticizer e.g. dioctylphthalate, tricresylphosphate, chlorinated biphenyls or mineral oil, may be incorporated in the resist to improve the washoff characteristics. In examples, a composition comprising N-vinylcarbacole, carbon tetrabromide, polystyrene and eicesane in benzene coated on a copper foil phenol formaldehyde resin laminate, exposed, heated by infra-red and washed with benzene to remove the unexposed portion. Copper in the exposed portions is removed with an acidic ferric chloride solution and then the resist is removed by dissolving in acetone leaving a copper image. In another example, the composition is reflex exposed to the far ultra-violet, exposed to infra-red and the unexposed portions removed with benzene. The developed image was contacted with an acetone-sponged paper and transferred to the paper, inked up and used as a printing plate. Printing plates are made by applying the composition to a hydrophilic surface, exposing and obtaining the resist as above, the resist being hydrophobic and ink receptive. Specifications 916,779, 941,488, 959,033, 959,034, 959,035 and 959,036 are referred to.

Abstract: A stratified heavy-current cryotron (see Division H1) is produced by depositing alternate layers of a superconductor and an insulator on an insulating substrate.  In a first embodiment, Fig. 1 (not shown), a substrate (3), provided with a cooler (2), has alternate layers of lead and lacquer deposited on to its surface from evaporator (8) and atomizer (7).  During the spraying of the lacquer layers the ends of the substrate are covered by electro-magnetically controlled masks (5) so that the ends of the lead layers contact one another.  A plurality of substrates may be simultaneously treated, or may be mounted on an endless band, a chain, or a revolving conveyer and passed through a number of chambers.  In a second embodiment, Fig. 2 (not shown) the substrate is in the form of a tape wound spirally round a drum (14) which is surrounded by chambers (16), (17), (18), (22), (24), (25) separated by airlocks (15).  Radiant heaters (20) and cooling tubes (19) are located inside drum (14) opposite chamber (18) and chambers (16), (24), (17) and (22) respectively.  Lead is deposited on the tape in chamber (16), magnesium is deposited on to the lead layer in chamber (17) and the magnesium is oxidized in chamber (18).  The drum is stepped one third of a revolution between operations, chambers (24) and (25) serving to mask parts of the tape so that the lead layers are divided into sections the ends of each of which are not covered by the oxidized magnesium. In chamber (22) a hard superconductor is deposited across the ends of adjacent sections to maintain the thickness of the strip and to provide connection areas.  The drum may also be rotated continuously to produce long strips.  The superconductor may also be niobium, vanadium, tantalum, tin or indium or alloys of lead, tin and indium.  The insulating layer may be of aluminium oxide or silicon oxide or may be produced by chemical conversion of the surface of the superconductor into an insulator.

Abstract: 550,094. Automatic volume control. PHILIPS LAMPS, Ltd., (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Oct. 14, 1941, No. 13234. [Class 40 (iv)] A volume-range expander comprises a network 3 which includes a non-linear resistance and in which signals are combined with pulses the duration of which depends on the instantaneous amplitude of the signal envelope or in which a current representing the signal envelope is combined with pulses of a duration depending on the instantaneous amplitude of the signals. It is demonstrated that with a suitably high pulse-frequency, unwanted modulation products can be filtered out as at 24, the effective output consisting of currents of the signal frequency having an amplitude which depends on the law connecting the signal amplitude with the pulse duration. In the arrangement described, the pulse duration is in a linear relationship to the signal amplitude and in consequence the output signal amplitude is proportional to the square of the input signal amplitude. As shown, the pulses are produced by combining envelope waves obtained by rectifying and filtering the signal with saw-tooth, waves generated at 16 in the grid circuit of a valve 18, the pulse voltages appearing across the.anode resistance 23.
