Title: Improvements relating to solid state radiation detectors
Inventor: FRECK DAVID VERNON
IPC: H01L31/117
Filed: 1961-10-04
Abstract: 1,038,041. PIN junction devices. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 24, 1962 [Oct. 4, 1961], No. 35776/61. Heading H1K. A PIN junction device for use as an X-ray or #-ray detector, made by treating a P-type semi-conductor member having an atomic number of at least 30 by a process in which lithium is diffused into the heated semiconductor to form a PN junction and then a reverse electrical bias is applied to the junction, after cooling to a lower temperature, to increase the thickness of the depletion layer and form a PIN junction, is connected to a pulse height analyser. In the particular embodiment described a heated circular wafer of P-type germanium is located downstream, in an argon gas supply, of a heated lithium source so that lithium diffuses into the germanium to form a PN junction. A further layer of aluminium is then deposited over the lithium to prevent oxidation and the specimen placed in an evacuated container and mounted on a protrusion in the base of a copper cylinder. The junction is then " drifted " by an ion drift process to give a PIN structure and at the, by now, reduced temperature of the junction a reverse bias is applied across the junction causing the depletion layer to increase in thickness. To prevent thermal runaway at this stage the device is connected into a control circuit (Fig. 7, not shown). The container with the germanium specimen 10 is then cooled by liquid air in a Dewar vessel into which dip fins from the cylinder 4, to reduce to a negligible value the reverse current of the junction. The device is then connected into an X-ray or #-ray detector circuit (Fig. 8, not shown) incorporating a pulse amplifier and pulse height analyser. An alternative to vapour deposition of the lithium on the germanium wafer is merely the heating of the germanium body with a layer of solid lithium supported on one surface. The device may be encapsulated and sealed in a vacuum or alternatively in a container which is continuously pumped.

Title: Manufacture of azo-dyestuffs and metal compounds thereof
IPC: C09B45/16
Filed: 1934-12-13
Abstract: o-Oxyazo dyes are prepared by combining with a coupling component adapted after coupling to form complex metal compounds, a diazo compound of an o-aminophenol or o-amino naphthol containing in the nucleus one or more hydroaromatic substituents, or of a substitution product of such an o-aminophenol or o-aminonaphthol.  The products can be converted into metal compounds by treatment with an agent yielding metal and such treatment may occur before, during or after the application of the dyestuffs for dyeing or colouring.  Suitable metal compounds are cobalt and chromium, and also there may be used copper, iron and other metals.  Fat-soluble dyes are free from sulpho groups which render the products water soluble.  In examples: (1) 1-(4-oxy-3-aminophenyl)-hexahydrobenzene is diazotized and coupled with 2-oxynaphthalene; the dyestuff treated with cobalt chloride yields a complex compound readily soluble in organic compounds with a red-violet colour; (2) diazotized 1 - (4 - oxy - 5 - nitro - 3 - aminophenyl) - hexahydrobenzene is coupled with 2-aminonaphthalene hydrochloride; the product on treatment with cobalt hydroxide in pyridine yields a compound imparting blue-black to greenish-black shades to organic compounds; (3) diazotized 1-(4-oxy-5-nitro-3-aminophenyl) hexahydrobenzene is coupled with 1-acetamino-8-oxynaphthalene-4-sulphonic acid; it dyes wool with a metachrome mordant in blue shades; using 1-oxynaphthalene-4-sulphonic acid as the coupling component a dye is obtained giving violet shades on wool in the presence of a metachrome mordant.  The o-aminophenols and o-aminonaphthols used as starting materials are generally prepared by nitrating the corresponding substituted phenol or naphthol and reducing the product; in this way 1-(4-oxy-3-aminophenyl)-hexahydrobenzene can be prepared from p-cyclohexylphenol, and by dinitrating the latter and reducing one nitro group there is obtained 1-(4-oxy-5-nitro-3-aminophenyl) - hexahydrobenzene. Specification 336,580, [Class 2 (iii)], is referred to.ALSO:o-Oxyazo dyes prepared by combining with a coupling component a diazotized o-aminophenol or o-aminonaphthol containing in the nucleus one or more hydroaromatic substituents, or of a substitution product of such an o-aminophenol or o-aminonaphthol are, when free from sulpho groups, soluble in fats.  The dyes can be converted into metal compounds by treatment with an agent yielding metal and this treatment may take place before, during or after the application of the products for dyeing or colouring; cobalt and chromium are specially suitable metals for this treatment.  Examples of the preparation of the dyes are given.

Abstract: 1,214,801. Torpedoes. LICENTIA PATENTVERWALTUNGS G.m.b.H. 23 Aug., 1965, No. 36149/65. Heading B7A. In a remotely controlled torpedo, electric signals are transmitted over a wire connected between the torpedo tube in the submarine, and the torpedo. A flexible protective tube, through which the wire passes, is capable of uncoiling with the wire but extends for only a limited distance from the submarine. When the torpedo reaches this distance from the torpedo tube, a coupling at the torpedo opens, and the torpedo proceeds, together with the control wire, beyond the end of the protective tube. The arrangement provides protection for the control wire in the vicinity of the vessel and occupies a minimum space prior to firing. Beyond the protective tube, the control wire lies freely in the water. After the torpedo has hit the target, the protective tube is separated from the submarine by a severing device in the torpedo tube.
