Title: Improvements in or relating to the production of a gaseous mixture containing carbon monoxide and hydrogen
Inventor: CARKEEK CHARLES RUSSELL
IPC: C10J3/46
Filed: 1953-11-06
Abstract: 734,475. Gasifying carbonaceous fuels. TEXACO DEVELOPMENT CORPORATION. Nov. 6, 1953, No. 30745/53. Classes 55 (1) and 55 (2). In a process for producing gaseous mixtures containing CO and H 2  from carbonaceous fuels the fuel is reacted with a gas containing free oxygen, e.g. pure oxygen or oxygen-enriched air, with or without steam, to produce a gas containing CO and H 2  and entrained carbon particles, the carbon particles are removed from the gas by washing with water and the resulting dispersion of carbon particles in water is, preferably after being converted to a slurry, introduced into or mixed with a liquid hydrocarbon and the liquid hydrocarbon containing carbon particles is reacted with a gas containing free oxygen. Some of the water in the slurry may be introduced with the oil and carbon particles. The fuel may be solid, liquid or gaseous. Where a gaseous or solid fuel is used the oil containing carbon may be fed in conjunction with the primary feed material in a combination burner or may be utilized in either a separate burner in the same generator, or in a separate gas generator. When a liquid, e.g. a heavy hydrocarbon oil is the primary fuel, the liquid is reacted with oxygen in a gas generator comprising an unobstructed reaction zone, steam being supplied to control the temperature. In this case the oil containing carbon preferably forms at least part of the feed to the gas generator. The water used for washing the carbon particles from the gases may contain a wetting agent, e.g. a water-soluble oxygenated hydrocarbon. The washing may be effected in a countercurrent gas-liquid contact apparatus such as a bubble tray column.

Title: Improvements in apparatus for the reproduction of sound films
IPC: G11B7/00
Filed: 1937-11-10
Abstract: 501,218. Reproduction of recorded sound. KOLB, 0. K. Nov. 10, 1937, No. 30862. [Class 40 (ii)] An apparatus for the reproduction of sound film records either of the asymmetric type or single hump type is characterized by the provision of optical elements adaptable for either type. Light from a source 1 passes through a condenser 3 to the asymmetric sound track 2 moving perpendicular to the plane of the drawing and an enlarged image of this track is focused by lens 4 on a transverse slit 5. Behind this slit are two narrow angle prisms 6a, 6b arranged with their refracting edges contiguous and in line with the centre of the image of the sound track. Refraction by these prisms results in separation of the two half images and each is arranged to fall on a separate photo-sensitive element 7a, 7b. If the track is not of the push-pull type, the two prisms, which are mounted in a carriage, are moved in the direction of the arrow so that one prism 6b covers the whole of the slit 5 and light from the whole width of the sound track is refracted to one photo-sensitive element 7b only. Instead of two prisms, two lenses may be used to form the half images for push-pull records, there being provided a separate single lens for other records, Fig. 2 (not shown). In this latter case, a rotatable turret may be used in place of the carriage, Fig. 3 (not shown). Specification 494,201 is referred to.

Abstract: 796,870. Delivering liquids. STRUVER GES. AGGREGATEBAU. A. Oct. 28, 1954 [Dec. 1, 1953], No. 31192/54. Class 116 [Also in Group XXIX]. The pressure at which liquid is delivered to two independent systems from a single pump 1, Fig. 1, is maintained constant, independently of variations in the flow to the two systems, by means which include a valve 30, 31 in the delivery to each system and a by-pass valve 54 in each system, both controlled by pressures in the associated delivery line. In the system illustrated fuel is delivered from a tank 10 by a pump 1 to hoses 2, 3 through filters 15 and meters 17. The valves 31, 30 are connected to form a twin shuttlelift valve controlled by pistons 39, 38 influenced through pipes 48, 50 by the pressure at pitot tubes 49, 51 and through pipes 53, 52 by the pressures at the throats of venturi tubes 18. The pressures in the venturis are also communicated by pipes 73 to diaphragms 70 controlling relay valves 64 controlled by springs 66. The valves 64 connect the pressure in the pump delivery pipe 12 through a reducing valve 61 and pipes 62, 60, 59 to chambers, normally connected through restricted passages 78 to the intake of the pump, above pistons 57 arranged to open the by-pass valves 54 against the bias of springs 55 to return fuel to the pump intake. To compensate for the loss of head in the hoses 2, 3 an equivalent pressure difference derived from points 76, 77 in the delivery line 16 is communicated by pipes 74, 75 to influence a diaphragm 72 which assists in controlling the relay valve 64. In an alternative arrangement the pressure tappings on the venturis 18 are replaced by hoses extending through the delivery hoses 2, 3 to points adjacent the delivery valves 6, 7. The measurement of the controlling pressures for the valves 32, 33 and 64 may also be derived electrically. A four-way cock 19 permits delivery to be made to hoses carried by swinging posts 81 instead of to the hoses 2, 3. As shown in Fig. 5 the cock 19 includes ports 86, 87 fed hrough pipes 88, 89 from the delivery line 16 and ports 84. 85 connected by a pipe 91 to the working side of the diaphragm 70 of the valve 64 so that, when the cock is turned to an intermediate position such as that shown in Fig. 5 valves 64 open to cause the valves 54 to return the delivery from the valves 32, 33 to the intake of the pump Specification 788,818 is referred to.

Title: Improvements in or relating to machines for treating ramie and like material
IPC: D01B1/22
Filed: 1926-12-11
Abstract: 262,815. Lens, J. de. Sof, I., and Nicolas, A. Dec. 12, 1923, [Convention date]. Void [Published under Sect. 91 of the Acts]. Decorticating. ramie &c.-The stems of ramie after being broken by a pair of deeply fluted rollers are laid on a table 24, which is moved forward, either automatically or by hand, to insert the ends of the stems through pairs of jaws 5, 6, 5<1>, 6<1>, 7, 8 into the grip of a pair of rollers 35, 37. The table is then moved back, and as the rollers draw the stems forward the centre jaws move up and down, bending and rubbing the fibre upon itself. The jaws may be corrugated and be hollow, to allow water to be circulated through them to prevent heating of the fibre. The jaws 7, 8 are connected by rods 23 to pins 20, 22 sliding in slots 19, 21 in a lever 17 oscillated about its pivot 18 by a crank 11, link 12, and pin 13 sliding in a slot 16. The lever 17 is carried by the table 24, so that as the table is moved the amplitude of the reciprocation imparted to the jaws 7, 8 is changed. The divergence of the grooves 19, 21 separates the jaws 7, 8 as the table is moved forward. The jaws 5, 5<1> are raised, to allow the stems to be inserted between them by a pin 33 on the table 24 engaging and turning a lever 25 connected by a link 27 to a lever 28, 30, which carries a gear 32 engaging a gear 32<1> on a lever 30<1>. and a link 31 carrying the jaw 5. The lever 30<1> is linked to the jaw 5'. The roller 37 is carried by a pivoted arm and is drawn by a spring towards the roller 35 which is driven. The table carries an incline adapted to engage a projection on a second arm on the same pivot and raise the roller 37 to allow the stems to be inserted between the rollers. As the table is moved back the projection, which has passed beyond the incline, is engaged by the underneath of the incline, drawing the arms down to cause the rollers to engage and grip the stems.
