Title: Improvements in or relating to electric cables with compressed gas insulation
Inventor: SKIPPER DONALD JOHN
IPC: H01B9/06
Filed: 1965-01-11
Abstract: 1,073,606. Gas-filled cables. CENTRAL ELECTRICITY GENERATING BOARD. Nov. 10, 1965 [Jan. 11, 1965], No. 1216/65. Addition to 967,012. Heading H1A. In a compressed gas insulated cable, an inner conductor is located within a concentric support by means of a plurality of separate spacers of dielectric material each consisting of an inner tube, or part of a tube joined to a coaxial outer tube or part of a tube by webs extending in a direction such that, in any radial plane, the length of the path through the solid dielectric material is small compared with that through the gas. As shown in longitudinal section, a stranded or segmental copper or aluminium conductor 1 is surrounded by a screen 2 of extruded or lapped tapes of conductive material which in turn is surrounded by an insulating layer 3. Spacers 4 consist of tubular portions 10 and 12 joined together by webs 11. Inner portion 10 is a sliding fit on layer 3 and has an axial length shorter than that of outer portion 12. Adjacent outer portions are connected by a linking element 5 engaging grooves 13. The outer support consists of lapped layers of insulating and conducting material. As best seen in Fig. 2 (not shown), the webs lie in planes which are non- radial but parallel to or inclined to the axis of the cable. To manufacture the cable, the injection-moulded spacers may be assembled with the outer layers and drawn into an oversized aluminium tube. The screened insulated conductor is drawn through the assembly and the aluminium tube passed through a sinking die or corrugating head. Alternatively, the spacer elements may consist of semi-circular or other part-circular elements which can be fitted round the conductor and are bound together by the outer layers. The gas insulation may be sulphur hexafluoride with or without nitrogen at a pressure between 200 and 500 p.s.i.

Title: A metallurgical vessel
IPC: C21C5/46
Filed: 1968-01-09
Abstract: 1,218,441. Mounting converters. DEMAG A.G. 9 Jan., 1968 [28 June, 1967], No. 1293/68. Heading F4B. A converter vessel is supported within a mounting rung 4 by means of peripherally spaced resiliently extensible bolts 20 which connect upstanding portions 30 of the mounting ring to brackets 3, 31 welded to the jacket 2 of the vessel. The bolts 20 pass through slotted apertures 19 elongated radially of the vessel in both the brackets 3, 3<SP>1</SP> and the portions 30 and are provided with washers 22, 23 having cooperating part spherical seating surfaces, which allow the bolts 20 to pivot in the apertures 19 and so compensate for differential radial expansion of the vessel and the ring. Differential axial expansions of the vessel and the ring are taken up by elongation of the bolts. The bolts may be slightly inclined to the longitudinal axis of the vessel to improve the rigidity of the structure. The ring 4 may comprise a trunnion ring, or in the case of a Kaldo converter, form the lower of two track rings interconnected by a spacer ring 5 secured to the track rings by further resiliently extensible bolts 14, the brackets 3, 3<SP>1</SP> on the vessel projecting into recesses 12 in the spacer ring 5. Bracing members 29 extend between the upstanding portions 30 of the mounting ring 4 and flanges 16 welded to the vessel jacket 2. Further bracing members (26, Fig. 6, not shown) extend between the portions 30 and the spacer ring 5. These bracing members help prevent bending stresses being applied to the resiliently extensible bolts 20. In modifications (not shown) a bolt head or threaded nut having a part-spherical seating surface may replace one of the washers, and the bolts may be provided in radially or circumferentially disposed groups around the vessel periphery. Suspension lugs (10, Fig. 1, not shown) may be attached to the vessel jacket or to its upper track ring.

Patent GB-394899-A (GB)
Title: Method of and apparatus for electrically precipitating suspended particles from a gas
IPC: B03C3/36
Filed: 1933-01-18
Abstract: <PICT:0394899/III/1> In a process for the electrical precipitation of suspended particles from gases, the gas is passed into a precipitating chamber through a number of gas inlets arranged along its length. The distances between the inlets and/or the amounts of gas introduced at the different points may be so adjusted that the concentration of suspended matter is substantially uniform throughout the region in which the gas is introduced.  According to the arrangement shown in Fig. 1, the gases are passed from a distributing chamber 12 through a series of openings 10a . . 10e arranged longitudinally in a cylinder 1 which acts as a separating chamber and a collecting electrode, having a centrally disposed discharge electrode 6.  The cleaned gas is removed through the outlet 13 and the separated material through the trap 9 in the collecting chamber 8.  The gas may be introduced in a direction substantially opposite to the main gas flow by providing an outwardly projecting lip 17 on each inlet 10, as shown in Fig. 2, thus preventing movement of the discharge electrode.  The outward bending of the edges of the inlets 10 also prevents arcing at these points.  A similar arrangement may be applied to a precipitator having a number of cylindrical collecting electrodes arranged in parallel in a distributing chamber. In this case, the gas is preferably introduced into the distribution chamber with substantially eddyless flow.  The openings may be provided with slides or dampers which may be manually or automatically adjusted.  The collecting electrodes may be divided into several sections, each surrounded by a chamber provided with means, preferably adjustable, whereby fresh gas is introduced, the electrode sections being also arranged to permit a continuous flow of gas along their length.

Title: A process for the preparation of tridecane-1:13-dicarboxylic acid or its ester, suitable for the preparation of exaltone (cyclopentadecanone)
Inventor: GHATGEY BHAUSAHEB BAPUSAHEB
IPC: C07C55/02
Filed: 1958-01-17
Abstract: Tridecane -1 : 13-dicarboxylic acid or its methyl or ethyl ester are prepared by (i) oxidising an ester of the formula CH3 (CH2) CH(OH) CH(OH)-R1-COOAlk with an a , b -glycol rupturing agent which will form aldehyde groups, preferably sodium metaperiodate, to give the semi-aldehyde ester of the formula OHC-R1-COOAlk, in which formula R1 represents -(CH2)11-or-(CH2)13-and Alk represents a methyl or ethyl group, and (ii) converting said semi-aldehyde ester into tridecane-1 : 13-dicarboxylic acid or its methyl or ethyl ester.  When R1 = -(CH2)13-, step (ii) may be effected by oxidising the semi-aldehyde ester in acetone solution with aqueous potassium permanganate solution in the presence of an acid, such as acetic acid, to yield a semi-acid ester which on alkaline hydrolysis and acidification yields tridecane-1 : 13-dicarboxylic acid.  The semi-aldehyde ester of brassylic acid in which R1 = -(CH2)4- may be oxidised with potassium permanganate to brassylic acid semi-ester which may be saponified to brassylic acid or esterified to diethyl brassylate.  The latter can be converted to the diol, dibromide, dinitrile and thus to tridecane-1 : 13-dicarboxylic acid. Alternatively the semi-aldehyde ester may be subjected to the Knoevenagel Reaction with malonic ester or malonic acid, followed by hydrogenation, hydrolysis and decarboxylation to form tridecane-1 : 13-dicarboxylic acid. Alternatively the semi-aldehyde ester may be subjected to the Reformatsky reaction with a haloacetic ester, followed by dehydration, hydrogenation and hydrolysis, to form tridecane-1 : 13-dicarboxylic acid.  This product may be esterified to form the dimethyl or diethyl ester. The diethyl ester may be converted to the acyloin by reaction with sodium in xylene and the product reduced in alcoholic solution with zinc and hydrogen chloride to give cyclopent-decanone (exaltone).  The dihydroxy fatty acid ester starting material is obtained by oxidation of an unsaturated acid CH3 (CH2)7 CH=CH.  R1 COOH, for example, with hydrogen peroxide and acetic or formic acid in the presence of an acid catalyst, followed by esterification.  The unsaturated fatty acids utilised are erucic acid obtained from mustard oil and nervonic acid synthesised from erucic acid by a known process. For example erucic acid may be reduced to the alcohol and converted to the bromide which is reacted with malonic ester and the product hydrolysed and decarboxylated to give nervonic acid.

Title: Improvements in or relating to gas regulating apparatus
IPC: A62B9/02
Filed: 1953-01-21
Abstract: 719,025. Fluid-actuated valves. GARRETT CORPORATION. Jan. 21, 1953 [Jan. 28, 1952], No. 1735/53. Class 135. [Also in Group VI] In the demand valve of an underwater respiratory appliance the exhalation valve is mounted on the diaphragm and the inhalation valve is actuated through floating levers engaging the periphery of the diaphragm. Gas or air from a cylinder 16 passes through a filter 25 to the control valve 39 which is held on its seat by a spring 43. A plate member 34, around the valve stem, carries an upstanding. rim 49 which serves as a pivot for three levers 47, the upper ends of which bear on the underside of the diaphragm 13. The upper side of the diaphragm is exposed to the ambient fluid medium through holes 58 in the cover 12. Any reduction in the pressure in chamber 15, which is connected to the breathing mask through a tube 61, below the ambient pressure causes the diaphragm to open the demand valve by means of levers 47 bearing on the head 41 on the valve stem and thus the oxygen breathed is always at the pressure of the surroundings. The outer face of the diaphragm carries a flexible valve member 53 which normally closes ports 56 but, on exhalation, the slightly increased pressure in the chamber 15 thrusts the diaphragm outwards until the centre 54, of valve member 53, abuts against the stop 57 and thereafter lifts the valve member away from the ports 56 to allow the exhaled air to escape.
