Title: Interconnected continuous filaments
IPC: D01D5/253
Filed: 1965-01-13
Abstract: 1,102,051. Making interconnected filament bundles. G. SHAW. 13 Jan., 1965 [14 Jan., 1964], No. 1538/65. Heading B5B. [Also in Division A4] A multiplicity of relatively thick filaments interconnected along their length by thin webs which can be ruptured to separate the filaments are made by extruding an organic thermoplastic polymer, e.g. nylon, through an appropiately shaped slot-die. The resulting extrusion may be stretch oriented by pulling through a controlled heat zone 21 by parallel rolls 20, the set of rolls 19 supplying the necessary restraint, or by two sets of pinch rolls. A further heat zone and set of rolls may be used for controlled shrinkage. The filaments may be of circular, annular, rectangular, cruciform, T-shaped or H-shaped section, separation may be by drawing the extrusion over pins which pierce the webs. The interconnected filaments simplify subsequent operations, e.g. warp winding, and are of particular use in brush making, the filaments which are particularly uniform in crosssection being separated after assembly of the bundles into the knot holes of the brush blocks by standard brush-making operations such as trimming, sanding and flagging.
Patent GB-742996-A (GB)
Title: Di-sulfhydryl alkylene diamine polycarboxylic acids and salts thereof
Inventor: BERSWORTHY FREDERICK CHARLES
Filed: 1953-01-19
Abstract: The invention comprises di-sulphydryl alkylene diamine polycarboxylic acids and their salts of formula: <FORM:0742996/IV(a)/1> in which alkylene is <FORM:0742996/IV(a)/2> ; A is hydrogen or -CH2COOM and M is hydrogen, NH4, K, Na or an amine.  These compounds are water-soluble chelating agents for alkaline earth metals and for the transitional metals Fe, Co, Ni, Mn and Zn.  The di-sulphydryl ethylene diamine dicarboxylic acid is produced in alkaline pH aqueous solution by reacting two molar weights of the alkali metal salt of cysteine with one molar weight of an ethylene dihalide in alkaline solution.  The corresponding propylene <FORM:0742996/IV(a)/3> or trimethylene (-CH2.CH2.CH2-) disulphydryl compound may be obtained similarly by using the corresponding dihalide.  The disulphydryl ethylene diamine tetracarboxylic acid is produced from the dicarboxylic acid by reacting it with sodium cyanide and formaldehyde.  If desired the tricarboxylic acid may be obtained by displacing only one of the amino hydrogens with a carboxymethyl group.  Specification 600,629 is referred to.

Title: Improvements in and relating to means for maintaining approximately constant pressure in fluid insulating systems
IPC: H02G15/26
Filed: 1928-01-18
Abstract: 283,878. British Thomson-Houston Co., Ltd., (Assignees of Clark, W. S.). Jan. 18, 1927, [Convention date]. Cable joints. - To maintain approximately constant pressure, and to prevent admission of air, in a closed fluid insulating system for electrical apparatus, such as an oil-filled high tension underground cable, a closed reservoir communicating with the fluid system of the apparatus is provided with automatic means for admitting gas under pressure when the pressure in the apparatus falls. Means may also be provided for discharging gas when the pressure rises. The Figure shows the invention applied to a high tension underground cable 5 comprising conductors 6 stranded to Leave a central oil passage 7. Pipes 11 lead from reservoirs 12 to the oil passage 7, and enter the cable at joints 10 in the lead casing. The reservoirs 12 contain oil 13 under pressure from an inert gas, such as nitrogen or purified dry air. The top of the reservoir is closed by a flanged ring 14 and a plug 15 which carries a flexible metal diaphragm 16 of the bellows type, having a chamber 17 in communication with the atmosphere through a support 18. Flow of oil to the cable lowers the gas pressure in the reservoir 12, so that the diaphragm 16 actuates, through a lever 25, a valve 24 in a pipe 21 which leads to a gas-supply tank 19, the gas being shut off by the movement of the diaphragm when normal pressure is attained. A weighted safety valve 27 fitted in a pipe 28 is adapted to blow off at predetermined excess pressure in the reservoir 12. The tank 19 may be shut off from the reservoir by a. valve 23. In a modified construction, the gas from the tank 19 is maintained out of contact with the oil by a flexible metal bellows diaphragm which covers the oil in the bottom of the reservoir. The diaphragm may be controlled by weights or by an adjustable spring.

Coal, lignite or peat, which by itself is unsuitable for use in a coking process, is coked in admixture with an oil-coke obtained by quenching freshly-made hot coke in a heavy hydrocarbon oil. Marketable coke is thereby obtained, and also gaseous products which contain far more olefines than does gas produced by normal coking processes. In an example, 3 kilograms of coking coal are coked at a temperature of 1100‹ C.; and the hot coke is immersed in a bath charged with commercial fuel oil at a temperature of 120‹ C. There is thereby obtained 2639 grams of coke which contains 28.8 per cent by weight of oil. The cracking gas contains 37 per cent methane, 31 per cent hydrogen, 25 per cent olefines and 3 per cent carbon monoxide. The oil-coke is mixed with coal in the ratio of 1: 1; and the mixture is coked at a temperature of 1100‹ C. The coke so produced had a strength of 104 kg/cm.<SP>2</SP> and a porosity of 50 per cent by weight. The coke oven gas contained 53 per cent hydrogen, 34 per cent methane and 9 per cent ethylene.
