Title: Improvements in or relating to electric cables
IPC: H01P3/04
Filed: 1937-10-08
Abstract: 503,765. Electric cables, BLUMLEIN, A. D. Oct. 8, 1937, No. 27336. [Class 36] A flexible electric cable comprises at least two conductors arranged side by side, maintained in spaced relation, and insulated from one another by a common sheath of insulating material, the conductors being crinkled or otherwise deformed along their lengths so as to permit extension of the conductors when the insulating material is tensioned. In Figs. 1 and 2, the crinkled conductors 7, 8 are embedded in dumb-bell-shaped insulation 9 such as rubber. Alternatively, the conductors 7, 8 may be contained in air ducts spaced within the insulation 9, and this may have a cross-section substantially constant instead of the dumb-bell shape. The insulation may be in two sections, each provided with complementary grooves which, when the sections are secured together after insertion of the conductors, form the ducts. Suitable materials for this are paper or fabric treated with a thermoplastic insulator or the substance known by the Registered Trade Mark " Celastoid." The deformations on the conductors may be continuous or at intervals. In assembly, Fig. 6, the conductors 7, 8 are fed through crinkling rollers 15, 16 and then between the top and bottom sections of the insulations which are finally passed between heated rolls 17, 18, 19 to secure them together. This insulation may be stiff paper and the sections may be gummed together. The cable may be used as a down-lead for an aerial or as a high-power feeder. Specification 462,772 is referred to.

Patent GB-687838-A (GB)
Title: Method of stripping catalysts and apparatus therefor
IPC: B01J8/18
Filed: 1951-11-26
Abstract: <PICT:0687838/III/1> In a process wherein a finely-divided catalyst is continuously circulated through a reaction zone, a stripping zone, and a regeneration zone, the efficiency of the stripping stage is improved by continuously mixing a stream of hot regenerated catalyst from the regeneration zone with a stream of spent catalyst from the reaction zone, passing the resulting hot mixture downward through uprising stripping vapours, and collecting the catalyst as a bed which is maintained in the fluidized state by the passage of stripping gas.  As shown, regenerated catalyst introduced at 9 mixes in chamber 14 with spent catalyst introduced at 7, and the mixture falls via baffles 15, 17, 18 into the fluidized bed.  Stripping gas enters at 16, passes up vertical cells formed by baffles 19, and leaves the vessel at 20.  In a modification, Fig. V (not shown) the mixing chamber is open at the top and has a perforated bottom.  An example describes the application of the process to the cracking of gas oil; catalyst at 514 DEG C leaving the reactor is raised to 539 DEG C in the mixing chamber and is stripped with steam; deposits on the catalyst are cracked, and the stripped gases may be combined with the cracked reaction products.

Title: Improvements in or relating to the manufacture of flexible expanded thermoplastic materials
Inventor: GONDA DESIRE
IPC: C08J9/30
Filed: 1956-09-10
Abstract: <PICT:0860947/IV (a)/1> A process for the production of flexible expanded thermoplastic material comprises forming a fluid paste of the thermoplastic material and introducing it into a sealed vessel, discharging an inert gas under pressure into the lower part of the vessel so that the gas passes outwardly and upwardly through the fluid paste for dispersion therethrough, cutting off the supply of gas to the vessel and a releasing valve control means which allows the pressure differential between the interior and exterior of the vessel to discharge the contents of the vessel including all or substantially all the pressure gas therein as a creamy foaming mass through a siphon tube extending from substantially the bottom of the vessel to and through the upper part of the vessel, thorough dispersion of the gas in the fluid paste being achieved by turbulent dispersion set up during the introduction of the gas into the vessel and the withdrawal of the expanded material and gas simultaneously from the vessel.  The thermoplastic material may be a mixture of a high molecular weight polyvinyl chloride resin and a non-paste forming polyvinyl chloride resin.  These, in an example, are formed into a paste with the addition of tritolyl phosphate, lead silicate, barium stearate, cadmium stearate, silicone fluid, dioctyl phthalate and oleic acid.  The paste is introduced (in one embodiment) into a pressure vessel 1. Gas (e.g. nitrogen or carbon dioxide) is passed in from cylinder 12 through the tube 6 provided with holes 14 and holes in the bottom of the tube, all drilled tangentially to a circle within the tube to produce turbulence in the paste when the gas is introduced.  When the required pressure is reached first the closure valve 15 and then the trigger valve 17 are opened, with the nozzle 18 being directed into the mould.  The mould containing the ejected creamy foamy paste is then heated at 150-165 DEG  C.  The foamed mass can also be coated on to textiles or leather.
