Title: Improvements in or relating to containers for the isolation of radioactive matter
Inventor: WOLSTENHOLME STANLEY
IPC: G21F5/015
Filed: 1955-12-23
Abstract: A material for making a container for radioactive isotopes or other radioactive matter (see Group XX) is a resilient homogeneous unitary mass comprising lead or a lead compound and rubber or a synthetic resin made from polyvinyl chloride powder, polyvinylidene chloride, polystyrene, polyacrylates, or other thermoplastic resins.  Small amounts of polyvinyl acetates or polyvinylidene chloride may be added to polyvinyl chloride. Other optional additions are a plasticiser, for example dioctyl phthalate, dioctyl sebacate, or tricresyl phosphate, a stabiliser, for example dibutyl tin dilaurate or basic lead carbonate, a pigment, and a mould release agent.  Two examples are given of mixes containing polyvinyl chloride and lead powder; the mixes are heated to 160 DEG -200 DEG  C. for 30 minutes to 2 hours. A coloured surface may be given to the castings by spraying the interior of the mould at 100 DEG C. with a mixture of polyvinyl chloride, dicctyl phthalate, lead stearate, and a pigment.  In another example the mix comprises rubber, lead powder, litharge as an accelerator, sulphur as vulcanising agent, zinc oxide, and stearic acid; the mixture is heated at 141 DEG C. for 2 hours.  According to the Provisional Specification, tungsten powder may be used in place of lead or the lead compound.

Abstract: 1,196,507. Producing copper. S. HORI and T. OKABE. Aug.2, 1968 No.36982/68. Heading C7D. Metallic copper is produced by a wet process comprising reacting at least one of CuSO 4 , CuCO 3  and CuO and basic copper salts of these with at least one salt of alkali metals and alkaline earth metals which yields sulphite or hydrosulphite ions or with the hydroxide or carbonate of an alkali or alkaline earth metal in the presence of sulphurous acid, the reaction being carried out in a sealed vessel and in the presence of water. The sulphite or bisulphite salts are added in the ratio of 1-2 moles of said salt to 1 mole of copper in the copper compound, and the mixture heated in the ranges 100-150‹ C. or 140-190‹ C. to produce metallic copper slurry. The liquid of the slurry is, after seperaration of the copper, treated to recover sulphite salts or sulphurous acid, for use again in the process. If calcium bisulphite is used, the slurry solid contains copper and calcium sulphate dihydrate which are separated from each other by utilising their large difference of specific gravity.

Title: Manufacture and application of azo-dyestuffs
IPC: C09B45/16
Filed: 1934-12-24
Abstract: Chromiferous azo dyes are made by heating with an acid, other than an aliphatic acid, in an aqueous medium the complex chromium compounds of azo dyes of the formula <FORM:0449478/IV/1> wherein the three x's represent hydrogen atoms, of which at least one is exchanged for a sulphonic acid group and R = the residue of a coupling component containing a group capable of binding metal in complex union, the said heating being so conducted that the SO3H group in 4-position is exchanged for hydrogen.  The parent dyestuffs may be present in admixture either with each other or with other azo dyes capable of complex metal formation. In many cases it is possible to make the complex chromium compound and to heat it with an acid in aqueous medium in one operation. The products may be used for dyeing or colouring wool, silk, leather, varnishes made from cellulose, natural or artificial p  resins, or they may be used as pigments or in printing.  In examples the chromium compounds of dyes from the following components are treated with aqueous solutions of the following acids: 2-amino-1-naphthol - 4 : 8 -, 4 : 6- and 4 : 7 - disulphonic acids; a - or b -naphthol, 1-naphthol-8-sulphamide, 1 - (2<1> - methyl - 4<1> - sulpho) - or 1 - (3<1> - sulpho) - phenyl - and 1 - phenyl - 3 - methyl - 5 - pyrazolones, 1 - phenyl - 5 - pyrazolone - 3 - carboxylic acid, 2 - naphthol - 3 - carboxylic acid, 1 - naphthol - 8 - sulphonic acid, barbituric acid; naphthalene - 1 - or 2 - sulphonic acid, naphthalene-1 : 5-disulphonic acid, a - and b - naphthol mono- and poly-sulphonic acids, benzene mono-, di- and poly-sulphonic acids, sulphuric and other mineral acids, naphthalene di- and poly-sulphonic acids, 2-naphthol- 6-sulphonic acids, hydrochloric acid, benzene-sulphocarboxylic acids, phosphoric acid. In further examples the dyestuff 2-amino-1-naphthol-4 : 8-disulpho acid --> b -naphthol is heated with neutral chromium sulphate and naphthalene-1-sulphonic acid or other chroming agents and acids, e.g. chromium naphthalene-1- or 2-sulphonate or 1 : 5-disulphonate or with aqueous neutral chromium sulphate only.  According to the Provisional Specification complex metal compounds of azo dyes are made by heating in an aqueous medium the metal compound of an azo dye of the above general formula wherein the three x's represent hydrogen atoms, of which at least one may be exchanged for a sulpho group and R may also represent the residue of a diazo component.  In the latter case the parent azo dyes are made by coupling a diazo compound of the benzene or naphthalene series containg one or more groups capable of binding metal in complex union, with a 1-naphthol-4-sulphonic acid, e.g. the 4 : 6-, 4 : 7- or 4 : 8-disulphonic acid.
