Title: Thionophosphonic acid esters and process for their production
IPC: C07F9/40
Filed: 1960-10-05
Abstract: The invention comprises compounds of the general formula: -<FORM:0916564/IV (b)/1> wherein R is a C1-C4 alkyl radical or an aromatic radical, R1 is a C1-C4 alkyl radical, R2 is a C1-C4 alkyl radical, a phenyl radical, a C1-C4 alkyl substituted phenyl radical, a chlorosubstituted phenyl radical, a C1-C4 alkylmercapto-substituted phenyl radical, or a C1-C4 alkoxy-substituted phenyl radical, and Alkylene is an alkylene radical containing up to 4 carbon atoms, which may be substituted by another -S-R2 group.  They may be obtained by reacting appropriate alkyl or aryl dithiophosphonic acid anhydrides with thioether alkanols and subsequently further alkylating the compounds in the presence of an acid binding agent. The reaction is preferably carried out in an inert solvent e.g. a ketone or an aromatic hydrocarbon at room temperature or at a slightly elevated temperature.  Specified alkylating agents are compounds of the formula R1-Hal in which Hal is Cl, Br or I, e.g. methyl, ethyl or propyl iodide, and corresponding derivatives of sulphuric acid or toluene sulphonic acid e.g. dimethyl sulphate or ethyl p-toluene sulphonate.  Several examples are given.  The products have insecticidal properties (see Group VI).ALSO:An insecticidal composition contains a solid or liquid carrier or diluent and as active ingredient thionophosphonic acid ester of the formula <FORM:0916564/VI/1> in which R is a C1-C4 alkyl radical or an aromatic radical, R1 is a C1-C4 alkyl radical, R2 is a C1-C4 alkyl radical, a phenyl radical, a C1-C4 alkyl-substituted phenyl radical, a chloro-substituted phenyl radical, a C1-C4 alkyl-mercapto (or C1-C4 alkoxy) substituted phenyl radical and Alkylene is an alkylene radical containing up to 4 carbon atoms, which may be substituted by another -S-R2 group (see Group IV (b)).  Specified carriers or diluents are talc, chalk, bentonite, clay, water (if desired with an emulsifier), alcohols, ketones and liquid hydrocarbons.  The active ingredient may be used in conjunction with known insecticides and/or fertilizers.  A suitable composition is obtained by way of example by mixing the compound CH3.P(S)(SCH3)(OCH2CH2SC2H5) with the same amount of acetone, adding benzyl hydroxydiphenyl polyglycol ether as emulsifier and then diluting with water.

Filed: 1967-07-26
Abstract: 1,190,986. Fuel elements. REACTOR CENTRUM NEDERLAND. 26 July, 1967 [16 Sept., 1966], No. 34420/67. Heading G6C. [Also in Divisions G1 and H1] Fissile rods are tested for surface contamination by α-particle emitters by using a rod 1 as an electrode in an ionization chamber 22 and applying a low voltage (50-200 v.) to measure the primary ionization current caused by the α-particles. The rod 1 may be of UO 2  with a covering of Zr alloy. Compressed argon passes from a cylinder 11 through a reduction valve 10 to an inlet 7 of a stainless steel tube 6 forming an outer electrode and envelope of the chamber 22 and passes to an outlet 8 and valve 21 which is adjusted to maintain an overpressure of 0À1 to 1 atmosphere in the chamber. The rod 1 is slid together with supporting caps 4 and 5 of insulating material into the tube 6 and secured by a bayonet joint between the tube 6 and a metal hood 34 fixed to cap 4. A wire embedded in cap 4 is connected to a clamping spring (36) (Fig. 2, not shown) in the socket engaged by the end 2 of rod 1. The chamber 22 is connected through a loadsensitive preamplifier 16 and a main amplifier 17 to an analyzer 18 which may be multi-channel or single channel with a threshold discriminator to eliminate background radiation. Measurements are made with uncontaminated rods and subtracted from the measurements with contaminated rods to determine the contamination. A device (Fig. 3, not shown) for the successive testing of large numbers of rods includes a mechanical conveyer (23) for passing rods into and out of the chamber 22 and connected to the analyzer 18 by an electro-mechanical coupling enabling badly contaminated rods to be rejected.
Patent GB-400439-A (GB)
Title: Improved process for the production of regenerated wood from wood powders
IPC: B27N3/20
Filed: 1932-12-05
Abstract: Sawdust or other fine dry wood powder, without the addition of extraneous agglutinants, is raised to a temperature below the point of the decomposition of the natural binding ingredients which it contains and then is subjected to heavy pressure, so that the binding gums, resins, and the like which have been liberated by the heat, are spread evenly throughout the material by the pressure and consolidate the whole into a block of moulded wood, or a moulded article such as a tobacco-pipe.  The process is usually carried out in a hydraulic press with heated platens and mixtures of sawdust from various woods are preferable in order to equalize the varying amounts of binding material occurring naturally in the different kinds.  The temperature and pressure employed will vary with the kind of wood employed. Articles may also be moulded roughly by pressure only in halves, to be subsequently joined under heat and pressure in a finishing-mould. Fire-proofing elements and mineral fillers may be incorporated into the mixture.

Abstract: 1,139,036. Laminated plastics materials. DOW CHEMICAL CO. 1 Aug., 1966 [2 Aug., 1965 (3)], No. 34452/66. Heading B5N. [Also in Divisions A4 and B8] A packaging film is formed by laminating outer layers of a polyolefin, e.g. polyethylene to an inner layer of barrier resin, e.g. a halogenated hydrocarbon such as vinylidene chloride polymer. The layers may be joined by adhesives. The laminate may be formed by heat plastifying the barrier resin and the polyolefin and deforming the latter to form a layer about a core of the barrier resin. The whole is then deformed into a stream and then into a film and finally cooled. As an example of a five-layer film for packaging cigars (see Division B8), the outer layers are of low density polyethylene glued to the inner layer by a copolymer consisting of ethylene and vinyl acetate. The inner layer consists of a 0À2 mil thickness of vinylidene chloride, vinyl chloride, acetyl tributylcitrate, epoxidized soya bean oil and 4-tertiary butyl-salol, secured to a 0À1 mil thickness of a similar ethylene-vinyl acetate copolymer. Other barrier resins are fluorocarbon, fluorohydrocarbon and fluorohalohydrocarbon polymers.
