Title: Process for preparing a cross-linked porous copolymer
IPC: G01N30/88
Filed: 1971-12-10
Abstract: 1335585 Cross-linked porous copolymer MITSUBISHI CHEMICAL INDUSTRIES Ltd 10 Dec 1971 [19 Dec 1970] 57503/71 Heading C3C [Also in Divisions C2 and C5] A process for preparing a cyano-groupcontaining cross-linked porous copolymer comprises polymerizing an acrylonitrile or methacrylonitrile with a polyvinyl monomer in the presence of an organic solvent which is inert to these monomers, which acts as a solvent therefor and which can swell the copolymer produced and in the presence of a linear monovinyl polymer which is capable of forming a homogeneous liquid phase with the monomers and the solvent, and removing the linear polymer by extraction. The polyvinyl monomer may be one or more of divinyl benzene, divinyl toluene, divinyl naphthalene, trivinyl benzene, ethylene glycol diacrylate or ethylene glycol dimethacrylate and is suitably used in an amount 20-50% based on the weight of the monomer mixture. The linear monovinyl polymer may be one or more of polystyrene, polymethylstyrene, polyvinylacetate, polymethylacrylate or polymethylmethacrylate and is suitably used in an amount 1-100% based on the total weight of the monomer mixture. The organic solvent may be an aromatic unsubstituted hydrocarbon, e.g. benzene or toluene or a halogenated hydrocarbon, e.g. chlorobenzene or dichloroethane. The copolymerization may be carried out under bulk polymerization or suspension polymerization conditions. The extraction may be carried out by using an extracting solvent which is the same as the one added in the polymerization. The copolymers obtained by the present invention are used as fillers in gel permeation chromatography and the particles generally have a pore radius of 25-5000 , a surface area of 10-1000 m.<SP>2</SP>/gm. and a pore volume of 0À2-1À0 c.c./gm. Specific examples refer to copolymers obtained by copolymerizing acrylonitrile and divinyl benzene or ethyleneglycol dimethacrylate.

Abstract: 1459457 Chromatography SPETSIALNOE KONSTRUKTOR BJURO AKAD NAUK ESTON SSR 20 Dec 1973 59203/73 Heading B1H A method of chromatographic separation uses at least three chromatographic separating stages connected in a circulation loop, each stage comprising at least one chromatographic column and during a plurality of cycles successively acting as an enriching stage, as a stripping stage and as a regenerating stage, the steps for each cycle comprising: continuously introducing the mixture to be separated into a pipe connecting the stripping stage to the enriching stage; recovering a fraction of the mixture enriched in more strongly adsorbed components at the outlet of the regenerating stage; recovering a fraction of the mixture enriched in less strongly adsorbed components at the outlet of the enriching stage, the separation and recovering of the fraction enriched in less strongly adsorbed components being carried out by means of a first carrier gas stream, the recovering of the fixation enriched in more strongly adsorbed components and regeneration of the separating stage being carried out by means of a second carrier or displacer gas stream; shifting the inlet point of the mixture and the inlet and outlet points of the said gas streams along the stages in the direction of gas flow periodically and simultaneously, each time the inlet of the separating stage previously regenerated being connected to the outlet of the separating stage into which formerly the mixture was introduced, the duration of the cycle between two succes sive shiftings of gas streams, the introducing rate of the mixture to be separated and carrier gas flow rate into the stripping stage being related so that at the moment of the subsequent shifting of gas streams when more adsorbed components to be removed from the outlet of a regenerating stage have reached the outlet of the enriching stage less adsorbed components to be removed from the outlet of an enriching stage have already left the stripping stage wholly entering the enriching stage. The displacer gas stream may comprise the most strongly adsorbed component of the feed stream. As shown column 3 acts as enriching stage, the mixture A + B to be separated being fed into its input and pure A removed from its output; column 1 represents the regenerating stage, pure B being obtained from its output by use of the separate gas flow W1, and 2 is the stripping stage. The carrier gas W2 flows through stripping and enriching stages.

A pair of torches are positioned in two corners of a chamber, and the apparatus 8 moved along the gantry to produce a fillet weld extending to the centre of each joint to be welded. The welding head is then pivoted to position the other pair of torches in the other two corners of the chamber, and movement of the apparatus 8 back along the gantry 7 causes the seams to be completed with slight overlap at the centres. The other opposite sides of the chamber are then welded in a similar manner after rotating the welding head through 90 degrees. In this manner the side walls 6 are fillet-welded to the floor 5 in each chamber.

Abstract: 786,299. Semi-conductor devices. SIEMENSSCHUCKERTWERKE AKT.-GES. June 28, 1955 [June 30, 1954], No. 18661/55. Class 37. [Also in Group XXXV] A Hall effect device comprises a thin wafer 2 of semi-conductor embedded with its connections in a protective member 1 of electric insulating material. The semi-conductor wafer may be ground or etched to a desired thickness while embedded in the material. Further means to facilitate the production of very thin wafers includes providing a layer of plastic material between the lower surface of the wafer and the insulating member, or strengthening the member by additional ribs during the grinding operation, and then removing these ribs from the member, since in the finished device, the latter is required to be thin in the direction of the magnetic field. Connections 10 and 11 between the Hall electrodes and tags 12 and 13 are twisted to eliminate induction effects. In an alternative arrangement, lead 10 is connected to electrode 8 by two parallel leads each surrounding half the wafer 2. The semi-conductor may consist of AIII-BV material. The insulating member may consist of a castable resin such as an ethoxyline or polyester resin, or of a ferrite or other non-conducting magnetic material, or of a mixture of a ferrite powder and a castable resin. Cooling of the device may be facilitated by using for the protective member, material of good thermal conductivity, such as a castable resin having quartz seal or non-conductive metal oxides added to it. In addition, the protective member may be extended beyond the semi-conductor wafer to provide a cooling surface, or projecting cooling plates may also be embedded in the member. The core used in producing the magnetic field may be utilized for heat dissipation. Specifications 719,873 and 759,047 are referred to.
