Patent GB-708957-A (GB)
Title: Method of producing gel-type inorganic oxide catalysts
IPC: C10G35/06
Filed: 1951-09-25
Abstract: Hydrocarbons are converted at elevated temperatures using a gel-type inorganic oxide catalyst prepared by precipitating a hydrous inorganic oxide in the presence of an aqueous dispersion of 3-30 per cent., based on anhydrous oxide, of an organic material having a molecular weight of about 1 x 103 to 1 x 107; the organic material is present in the precipitated gel as an internal dispersed phase, and is decomposed by calcining the washed and dried gel, to form a highly porous catalyst, which is mechanically stable and may be pelleted. Reference is mad to individual or plural gel catalysts containing the oxides of silicon, aluminium, chromium, molybdenum, magnesium, iron, vanadium, manganese, copper, nickel, titanium, thorium, zirconium, and tungsten; an alumina base may be impregnated with ammonium molybdate or chromate, or chloroplatinic acid.  Suitable organic materials are gelatins, glues, pectin, potato starch, dried skim milk, hydrolysed starches, high molecular weight alcohols and esters, methyl cellulose, dispersed natural cellulose, rubber latex, water-soluble derivatives of propylene polymers, bacteria and moulds. Preferably the organic additive has a molecular weight 102 to 104 times the molecular weight of the hydrocarbon charge stock.  Examples describe the preparation of catalysts (1) by co-precipitation of silica-alumina gel in the presence of natural rubber latex; (2) by co-precipitation of molybdena-alumina gel in the presence of animal glue.  The catalysts are useful in processes involving cracking (e.g. of gas oil), reforming (e.g. of petroleum naphthas), dehydrogenation, hydrogenation, isomerisation and cyclisation.  Tables are given relating to the use of the catalysts in cracking and hydroforming, and to the regeneration of a cracking catalyst.

Abstract: 598,141. Pulverulent-fuel furnaces. BABCOCK & WILCOX, Ltd. Aug. 31, 1945, No. 22442. Convention date, Aug. 31, 1944. [Class 51 (i)] [Also in Group XIII] In. pulverulent - fuel combustion apparatus of the kind comprising a chamber of circular section formed with fluid-cooled circumferential walls adapted to be swept by hot, particleladen gases whirling about the longitudinal axis of the chamber and progressing axially through the chamber and to be coated with molten slag, a second chamber formed with an inlet for the passage of gases from the first chamber, a refractory screen disposed in the second chamber, opposed to the inlet and arranged to be fluid-cooled and a slag outlet from the second chamber, the gas flow path in the second chamber beyond the refractory screen is divided into lanes by widely spaced rows of contiguous tubes adapted to be fluid cooled. A primary pulverulent fuel fired furnace chamber 25 has its circular boundary walls formed by closely spaced studded tubes 43 covered by a layer of refractory material. The outer end part of the furnace 25 is tapered and formed by tubes 46, Fig. 6, carrying flat plate studs welded together to form a smooth surface forming a continuation of a jacketed coal burner 50. An involute-curved damper-controlled primary air-coal pipe 53 opens tangentially into this conical part and from a tertiary air pipe 57 a whirling stream of air is supplied axially to the chamber. A series of adjacent tangential peripheral damper-controlled secondary air inlets, between the gas outlet and the burner, are formed by suitably bending the wall pipes 43. All the inlets are connected to a main air duct 41 supplied with air by a forced draught fan 38, the pressure of this fan and of an induced draught fan 37, being so adjusted that a positive pressure is maintained in the chamber 25, a neutral pressure in the lower part of a secondary chamber 29 and a negative pressure throughout the remainder of the unit. The discharge end of the primary chamber 25 is formed with a rearwardly flaring throat 75 formed by suitably bent upwardly-extending end wall tubes 73. A slag outlet 78 from the chamber 25 and one 93 from the chamber 29 are provided, The secondary furnace chamber 29 is lined with tubes and includes a row of inclined tubes 100 the lower parts of which are studded and covered with refractory material to form an inclined reflecting arch 30 opposite the gas outlet 75. Below the arch the tubes 100 are bent into transversely spaced vertically aligned tube groups which define a slag screen 31, a similar secondary slag screen 112 is formed above the screen 31 by the lower parts of tubes 110 whose upper parts form tube platens 32. An inclined tube baffle 116 above the platens 32 deflects rising combustion gases to contact successively steam superheater sections 33, 34, a steam generating tube bank 35 and a tubular air heater 36. Specification 552,747 is referred to.

Title: Transport systems utilizing a track supplied with fluid under pressure
IPC: B65G51/03
Filed: 1971-04-19
Abstract: 1338104 Air cushion tracked transport system BERTIN & CIE 19 April 1971 [27 Feb 1970] 22710/71 Heading B7L [Also in Division B8] A transport system comprises a track 1, which includes a reservoir 8 for a pressure-fluid, and a load 2 supported from the track by a cushion of the pressure fluid supplied from orifices 25 via a distribution unit 11 and conduit 24, the unit 11 only supplying the pressure fluid to a section of the track when a load is detected thereon by the blocking of orifice 14 by edge 20 of the load and preventing venting of reservoir 8 via distributer 30. When blocking takes place fluid from the distributer is routed to flip-flop 15. Should another load be located downstream of load 2 at less than a safe distance fluid bleed through a conduit 36<SP>1</SP> is routed through conduit 16<SP>1</SP> and actuates flip-flop 15. The fluid from conduit 36 is then diverted to the atmosphere at 17. If there is no load at less than a safe distance and conduit 36<SP>1</SP> is not pressurized, pressure fluid from conduit 36 flows through flip-flop 15 and actuates flip-flop 12. The supply of fluid previously directed tangentially to vortex valve 19 is then discharged to atmosphere through orifice 18 and the valve 19 supplies pressurized fluid on to the track. After the load has passed orifice 14 is no longer blocked and flip-flop 12 supplies fluid tangentially through duct 32 to valve 19 which then only discharges a small amount of pressure fluid to the atmosphere. In a modification separate vortex valves may be provided for each orifice 25. In a further embodiment, Fig. 5, valve member 40 normally prevents pressure fluid being supplied to the track but when a load is detected on the track section space 46 is vented and the member 40 drops allowing the pressure fluid to orifices 25. In a further embodiment, Fig. 7 (not shown), a valve closing member is supported on a flexible membrane.
