Patent GB-1502440-A (GB)
Title: Microcapsules
IPC: B01J13/18
Filed: 1975-08-20
Abstract: Double-walled microcapsules containing liquid filling material are constructed in such a way that they have an inner wall and an outer wall made of a polycondensate material, the outer wall, in particular, consisting of an aminoaldehyde polymer. The microcapsules are suitable for films in carbon-free duplicating sets and then contain a dye precursor. The preparation of microcapsules having aminoaldehyde polymer walls involves dispersing the water-insoluble filling material in an aqueous continuous phase. The continuous phase is admixed with an aminoaldehyde condensate, e.g. urea formaldehyde resin, and a water-soluble first polyfunctional reagent, e.g. diethylene triamine. The dispersed phase is admixed with a second polyfunctional reagent, e.g. terephthaloyl chloride, the two reagents condensing at the interfaces between the two phases to form the inner walls. Reduction of the pH of the continuous phase, in particular, serves to create the reaction conditions at which the precondensate polymerises to form a water-insoluble polymer which forms the outer walls. The microcapsules can easily be separated, filtered and dried and produce a flowable powder of capsules which easily rupture under pressure and which can be processed without difficulty.

Title: Improvements relating to the production of spandex filaments
Inventor: MCDONALD PETER DONALD
IPC: C08G18/80
Filed: 1964-08-25
Abstract: In making a spandex polymer in filament form by extruding a solution of a spandex precursor into a coagulating bath containing a difunctional compound reactive with isocyanate groups, the precursor is made by reacting a linear hydroxyl-terminated polyester or polyether with an excess of a major proportion of OCN-R-NCO, wherein R is a divalent hydrocarbon (h.c.) radical and a minor proportion of OCN-R1-R2-R3-R2-R1-NCO, wherei R1 is a divalent organic radical, R2 is -NH-CO-NH-, -NH-NH-CO-, -NH-CO-O- or -NH-CO-, and R3 is a divalent h.c..  Suitable isocyanates of the second formula can be made by reacting 1 mol of HO-R3-OH with 2 mols of OCN-R1-NCO to yield OCN-R1-NH-CO-O-R3-O-CO-NH-R1-NCO.  In examples, ethylene glycol and p,p1-diphenylmethane diisocyanate were heated together in dimethyl formamide to produce a mixture of 1 mol of <FORM:1109874/C3/1> and 1/2 mol of the diphenyl methane diisocyanate.  Thi mixture and a further 2 mols of the original isocyanate were added to a linear hydroxy-terminated polyester made by heating ethylene glycol, propylene glycol and adipic acid, the reaction mixture was diluted with tetrahydrofuran and the solution was extruded into an isopropanol solution of ethylene diamine.

[Also in Division H1] A superconductive circuit element includes two parallel extended super layers, a control conductor close to one of them and a gate conductor between it and the layer. The other superconductor layer has a through aperture with which both the gate and control conductor are in register over part of their length. By this means the current in the control conductor is concentrated on the surface adjacent the gate and thus maximum switching effect is obtained for a given control current. To avoid inductive coupling the control and gate conductors are preferably arranged to be mutually perpendicular. In the assembly shown in Fig. 2A and in part section in Fig. 2C, a transmission line 201 is led between pairs of overlapping substrates 202-207, each carrying cryotron gates 238, 240 (Fig. 2C), the intersection of the cryotron gates and control conductors 215, 216 of the line overlying apertures 242, 243 in the superconductive ground planes 235, 236. Insulation is provided between the layers as shown and the transmission line consists of an insulating tape 218 with comb-shaped metal foils on its surface (Fig. 2B), the section length being short in relation to the quarter wavelength of the signals in the line. The assembly may be used as a bit organized memory system with a bit word stored on each substrate and a transmission line corresponding to each word in the memory controlling one cryotron gate per substrate.

Title: Improvements in or relating to electron emitting cathodes for electric discharge devices
IPC: H01J9/04
Filed: 1929-11-14
Abstract: 339,451. Gramophone Co., Ltd., and Baker, G. B. Nov. 14, 1929. Vacuum tubes.-Electron emitting cathodes for electric discharge devices are prepared by coating a refractory core or an oxide-coated filament with a substance which, on heating in the absence of appreciable oxygen, leaves a residue containing the oxide of an electron-emitting metal and free carbon. The tartrates of the alkali or alkaline earth metals, for example caesiuum tartrate or barium tartrate, may be used as coating-substances which are applied either to a refractory core such as tungsten, platinum, or nickel or its alloys, or to an oxide coated filament comprising a refractory core coated with barium oxide which may contain free barium. The oxide coated filament or a filament of refractory material may be dipped into or drawn through a paste containing barium tartrate, barium carbonate preferably being added to the paste when the refractory filament is used. After coating, the filament is heated to a temperature between 800‹-1000‹ C. in an atmosphere of carbon dioxide, the coating of barium tartrate thus being converted into barium, oxide and free carbon. The barium oxide combines with the carbon dioxide present to form barium carbonate, and a filament having a coating of barium carbonate and free carbon is obtained.
