Title: Crystalline poly (methylene sulfide) and process for its preparation
IPC: C08G75/10
Filed: 1960-06-08
Abstract: A thermoplastic, crystalline, fibre-forming poly(methylene sulphide) having a melting point of at least 220 DEG C. is prepared by condensing methane dithiol or mercaptomethyl sulphide (HSCH2SCH2SH) in the presence of a basic catalyst at a temperature of 25 DEG  to 250 DEG C. while removing the hydrogen sulphide which is liberated. The product may be further treated with a mineral acid, e.g. hydrochloric acid, at a temperature of 90 DEG -100 DEG C., washed, dried and reheated above 100 DEG C. in the presence of an alkaline catalyst until no more H2S is evolved, to produce a polymer of higher melting point.  Suitable catalysts are ammonia, di- and tri-ethylamine, methylamine, n-hexylamine, tri-n-hexylamine, pyridine, piperidine, pentamethylene diethylene triamine, tributylamine, hydrazine, dimethyl formamide, dimethyl acetamide, triphenyl-phosphine, -arsine and -stilbene, and sodium hydroxide, carbonate, bicarbonate and sulphite.  The reaction may be effected in a medium such as tetramethylene sulphone, dimethyl acetamide, nitromethane, dimethyl formamide or mineral oil.  The products are compared with a poly(methylene sulphide) prepared from H2S and hexamethylene tetramine.  Uses: Fibres, films, tubes, rods &c.

IPC: G03D13/00
Filed: 1962-05-25
Abstract: 1,033,893. Photographic developing apparatus. HALL HARDING Ltd. Aug. 19,1963 [May 25, 1962], No.20184/62. Heading G2A. In an apparatus for the heat development of light-sensitive material in the form of cut sheets, the sheets are passed along a path which brings them close to a source of radiant heat, being guided generally by guiding elements, but not supported or in contact with any such elements in the immediate neighbourhood of the said source. The sheets to be developed are fed into the apparatus through an opening 44, between guide bars 54, 56, so that they are gripped between conveyer rollerdiscs 58, 60. When a sheet passes immediately under the heat lamp 52, it is not in contact with any supporting means, until it reaches the guide bars 62, on the other side of the heating zone E. Thus when the sheet carries a heat-developable diazo type material having an amino substance cocooned in a resin, which becomes momentarily soft or gummy as it is heated, there is not risk of this material sticking to any support. Above and below the heating zone E are ducts 48, 46 for cooling air. After development, the sheet passes between further roller-discs 68, 70 and out through delivery opening 72. In the form shown, the apparatus is housed in a casing 2 in the lower part of which there is a conventional printing arrangement comprising a transparent cylinder 22 and a light source 30.

Title: Field effect transistor with insulated-gate
IPC: H01L29/51
Filed: 1965-05-14
Abstract: 1,113,211. Field effect transistors. RADIO CORPORATION OF AMERICA. 14 May, 1965 [1 June, 1964], No. 20563/65. Heading H1K. In an insulated gate field effect transistor the rate of change of transconductance with gate voltage is caused to decrease as pinch off is approached by providing a continuous or stepwise variation transverse to the source-drain current path of the resistivity or dielectric constant of the channel, of the thickness or dielectric constant of the gate insulator, or of more than one of these variables. The device may have a channel of polycrystalline cadmium sulphide or selenide or tellurium. A preferred device, however, is made in multiple by diffusing phosphorus into an oxide masked P-type silicon wafer to provide N-type source and drain regions and then forming a stepped oxide layer with its associated inversion layer over the channel by surface oxidation followed by several photolithographic and partial etching steps. Metal is then evaporated over the entire oxide layer and etched to form the source, drain and gate electrodes. A further control electrode may be provided on the other face of the wafer, opposite the gate. Alternatively the oxide layer is vapour deposited, in which case the thickness is controlled by means of a movable mask and variation in the deposition rate. Similarly by simultaneous or sequential use of sources of different dielectrics layers of graded dielectric constant may be produced. The dielectric constant of the channel is varied in much the same way by epitaxial deposition of different semi-conductor materials side by side on a common substrate, while the resistivity is varied either by masking part of the channel during a gas discharge treatment or by diffusion from a superficial oxide layer of graded impurity concentration.
