Patent GB-686742-A (GB)
Title: A process for the preparation of a gaseous fuel for internal combustion engines
IPC: F02M27/02
Filed: 1948-06-22
Abstract: A method of preparing a gaseous fuel from a liquid hydrocarbon comprises a two-stage process carried out in the complete absence of air or oxygen wherein in the first stage the liquid hydrocarbon is gasified by gradual heating at an absolute pressure of 500-600 millimetres of mercury to a temperature <PICT:0686742/IV (b)/1> above its self-ignition point to disintegrate its heavy molecular compounds into hydrocarbons of simpler structure by releasing free hydrogen, and in the second stage the simpler hydrocarbons and free hydrogen are passed through incandescent tubes in the presence of heavy metal catalysts to combine them into hydrocarbons containing from 1 to 4 carbon atoms per molecule which remain gaseous after cooling, e.g. methane, ethane, ethylene, propane, propylene, butane, butylene, and butadiene. As applied to an internal-combustion engine, liquid fuel enters, through a pipe 1, an exhaust-heated chamber 2, fitted with transverse baffles, wherein the fuel is vaporized and its heavier molecular components split up, the vapour then passing by a pipe to a passage 6 from which it flows through exhaust-heated tubes 9 formed of a metallic catalyst, e.g. chromium, tungsten, or molybdenum, to reduce the fuel vapour to a stable gaseous fuel, which passes through a pipe 3 for mixture with the engine combustion air.  The exhaust gases enter a chamber 12 through ports 8, to heat the chamber 2 and flow over the tubes 9, and then pass through a pipe to a passage 5 through which they flow, heating the fuel vapour in the passage 6, to the exhaust pipe at 7.  The fuel in the chamber 2 is heated to about 580 DEG  C. under a pressure of 500-600 millimetres of mercury.

Title: Mechanically Treating Printed Surfaces to Prevent Smearing.
Inventor: MORSE SYDNEY HAROLD
IPC: B41F23/06
Filed: 1916-11-23
Abstract: 108,261. Morse, S. H. Nov. 23, 1916. Bronzing and the like; set-off, preventing; printed paper, finishing.-Relates to a method of preventing smearing of freshly-printed sheets by applying powdered French chalk or other suitable powder to the impression, and consists in passing the sheets through a closed chamber between two surfaces moving at equal speeds, the powder being applied to the sheets during their passage. The sheets are afterwards passed through an apparatus for removing surplus powder by abrasion. The powdering-apparatus shown in Fig. 1, comprises a closed chamber a provided with sheet inlet and outlet passages b, b<1>. A sheet-carrying belt f of canvas or other suitable material passes round rollers c, d and e arranged in the form of a triangle, and co-operates with a feed-roller g provided with chalk from a hopper l, an idle roller h, and a delivery roller j. The rollers g, j and the belts f, are geared to run at the same surface speed. A brush i, revolving at a higher speed, co-operates with a sheet support m to remove excess chalk from the sheets. This excess chalk partly returns to the hopper and partly falls on to the succeeding sheet as shown. The bristles of the brush i are preferably arranged spirally to conduct the chalk to one or both sides of the chamber. To prevent slip of the belt, one or more of the rollers carrying the belt is provided with a roughened surface which may be in the form of spirals extending from the centre towards the ends, or may be in the form of rings at each end of the roller. A grid r keeps the sheets flat against the belt f. To prevent the escape of chalk, packing-pieces such as o are arranged between the surfaces of the rollers e, j, c and the adjacent part of the casing. Chalk is removed from the back of the belt by a brush s<1> and falls into a trough s. Trays s<2> are arranged at the bottom of the casing. Fig. 5 shows the apparatus for removing the excess of chalk from the powdered sheets. The sheets are passed between a band u and skeleton drum v containing silver sand or other abrasive powder. The sand may be agitated by stirring paddles or brushes w which are rotated in the opposite direction from that of the drum.

Title: Improvements in electric cable installations
IPC: H02G15/26

Abstract: 439,575. Cables; cable joints. CALLENDER'S CABLE & CONSTRUCTION CO., Ltd., BRAZIER, L. G., and ROBINSON, D. M., Hamilton House, Victoria Embankment, London. June 7, 1934, No. 16907. [Classes 36 and 38 (i)] In a cable having impregnated paper insulation, the body of insulation is divided into two coaxial portions by a layer of material impervious to the impregnating materials present in the cable and the inner portion is flooded with mobile impregnating liquid which is supplied under pressure through the conductor of the cable from external reservoirs. The outer portion of the insulation is impregnated with a thicker liquid and does not communicate with a reservoir. The cable may be a stranded conductor 1, Fig. 3, having layers 2, 4 of insulation which are separated by an impermeable wrapping of oil silk tape 3, the insulating layer 4 being surrounded by a wrapping of metallized paper tape 11 which placed in electrical contact with the cable sheath 5 by a wrapped textile tape 12 containing interwoven copper wires. In modified constructions the impermeable layer consists of benzyl cellulose, or cellulose acetate and is applied by extrusion. Mobile insulating liquid is supplied to the insulating layer 2 through the interstices between the strands of the conductor. Fig. 1 shows an installation embodying the invention comprising two lengths of cable, a joint 6 and two alternative forms of terminal structure. The joint 6 is so formed as to preserve the continuity of the layers 2, 3, 4 between the two cable ends connected by the joint, and the two conductors 1 are connected together in a manner which does not cause blockage of the spaces between the conductor strands. The terminal structure shown at the left hand side of the Figure comprises a porcelain insulator 9 surrounding the cable end and filled with mobile insulating liquid which is maintained under pressure by a pressure reservoir 13 and which is in communication with the liquid contained within the inner layer of the cable insulation. The lead sheath 5 at the cable end is terminated by a stress cone 15, above which is applied insulation 16. An impermeable layer 17, which is connected at its upper end to the layer 3, is applied over the insulating layer 4 of the cable end to isolate this layer from the liquid within the insulator 9. The conductor 1 is connected to a terminal member 10 bv a flexible connection 14. In the construction shown at the right-hand side of the Figure,. the impermeable layer 17 is omitted and the insulator filled with viscous compound similar to that used in the insulating layer 4 of the cable, the insulating layer 2 being closed by a cap 19 which communicates with the pressure reservoir 13 containing the mobile liquid. The reservoir 13 may be exterior of the insulator, as shown, or may be arranged directly on the end of the conductor within a metal dome mounted on the top of the insulator.

Abstract: 456,378. Vehicle brakes. TEVES MASCHINEN-UND ARMATUREN-FABRIK GES., A., 23, Gustavsburgstrasse, Frankfort-on- Main, Germany. June 12, 1935, Nos. 16954 and 16955. Convention dates, Feb. 11 and April 16. [Class 103 (i)] In a brake system for a vehicle having two sets of brakes, separately operated, when one brake fails the operating-means'of this brake is connected to the operating-means of the other brake. A pedal 8 operates the wheel brake shoes by means of an hydraulic transmission 10. A hand lever 15 operates these shoes by mechanical connections 17, 22. A block 25 connected to the pedal 8 slides freely in a guide 24 connected to the lever 15. When the pressure in the hydraulic transmission fails a spring- pressed piston 28 releases a fork 26 to lock the block 25 to the slide 24 and the pedal 8 now operates the brakes by the lever 15. The spring 31 urging the piston 28 is sufficiently light to allow the normal release pressure in the hydraulic transmission to maintain the piston 28 depressed. In a modification, the pedal 8 operates a valve controlling a brake cylinder operated by compressed air and operating the brakes by an hydraulic transmission. The piston 28 is maintained depressed by the pressure in the compressed-air reservoir. This modification is shown applied to a brake system which may be operated from either end of the vehicle. In a further modification, a port is provided in the compressed-air cylinder past the position of the piston for full application of the brakes. If the hydraulic transmission fails the piston moves beyond this position, the compressed air escapes from the system and allows the piston 28 to rise.
