Title: Improvements in or relating to shaft bearing arrangements for low-temperature expansion turbines
Inventor: SCHREIBER BERNHARD
IPC: F25B9/06
Filed: 1970-07-29
Abstract: 1276059 Gas bearing LINDE AG 29 July 1970 [30 July 1969] 36656/70 Heading F2A [Also in Division F1] The shaft of a low-temperature expansion turbine is supported by a gas bearing adjacent the turbine and supplied with gas which is warmer than the gas entering the turbine nozzle ring. In one arrangement, Fig. 3, the rotor 2 of a low temperature turbine is mounted on a vertical shaft 1 supported at its upper end by a gas bearing having dynamic and static section 41, 42 and at its lower end by an oil lubricated bearing (not shown). Warming up gas can be fed to the gas bearing through line 14 and passage 46 in bearing bush 43. A diaphragm valve 47 operated by a mechanism 49 is response to pressure in the gas bearing controls the flow of high pressure gas through a line 48 to bush 43 and thus to the static section 42 and also, through bore 50, to load reducing pistons 51 for the bearing shells 44 of dynamic section 41 so as to render the latter inoperative when conditions are unsuitable. In a modification, Fig. 2, the gas bearing includes a shell 31 mounted so as to be able to tilt and loaded by a spring 32 and also by gas pressure acting on a piston 34 in chamber 33. The gas pressure is controlled by a diaphragm valve 35 in response to the differential pressure between bearing chamber 16 and the clearance space between turbine rotor 2 and nozzle ring 4, the pressure in the clearance space being speed dependent. The bearing supply line 36 is connected to a gas bottle 37 or a refrigeration circuit of the plant. In a further modification (Fig. 1, not shown), the gas bearing is similar to that in Fig. 2 and has tiltable shells (10, 11) supported by a bush (13) held by resilient rings (12) of P.T.F.E. or rubber in the turbine casing (3). The warmer gas exhausting from the gas bearing together with the gas leaking past turbine shaft seal (15) flow downwards towards an oil lubricated bearing (8) to prevent the upward penetration of oil mist from the latter. The oil lubricated bearing (8) acts as a radial and thrust bearing and its static parts are universally mounted on an external ring (20) through compensating links (17) and pairs of diametrically opposite balls (18, 19). The turbine shaft (1) is evacuated. The casing includes heat reflecting screens (24, 25) of aluminium foil. An oil brake (9) is provided to dissipate the turbine power. The turbine may form part of a liquefaction plant for helium or hydrogen, these gases being used in the turbine and the gas bearing.

Abstract: 839,721. Propelling vehicles. EISENWERK WESERHUTTE A. G. Nov. 27, 1957 [Dec. 7, 1956], No. 37036/57. Class 79(3) A load transporting means has power driven walking legs 2, 3, 4, Fig. 1, which are attached to the load 1, such as an excavating machine, and are movable in a vertical direction and in a horizontal plane in any direction relative to the load and relative to the ground. Each walking leg is attached to the load by one vertical extensible support, such as 5, and two horizontal extensible supports such as 6, 7. These supports may be fluid-operated rams connected to one another by ball and socket joints 15, 16 and to the load by further ball and socket joints 13, 14, the supports 5 being anchored against rotation about its own axis by a pair of triangular frames 29, 30, Fig. 7, pivoted on horizontal pins 28, 32 and interconnected at their apices by a cardan or ball and socket joint 31. A further ball and socket joint 11 connects each support 5.to a hollow, reinforced circular member 20 forming the leg. Starting from the position shown in Fig. 4, the support 6 is extended and the support 7' shortened to cause pivotal movement of the supports 5, 5<SP>1</SP> about the joints 11 so that the load 1 is swung forwardly in an arcuate path until it again rests on the ground with the supports 5, 5<SP>1</SP> inclined in the opposite direction from that shown. The supports 5, 5<SP>1</SP> are then temporarily shortened to enable them to be restored to their initial position in relation to the load in readiness for the next step forward. In an alternative method of operation, the supports 5, 5' are first vertical and are extended to lift the load which is then lowered by a forward arcuate movement about the joints 11, the supports 6, 7<SP>1</SP>, acting as brakes. A second set of walking legs, counterphased with the first, may be used so that the height of the load is kept constant. The supports 5 may be returned' to their initial positions after each step by arcuate movements about the joints 12, the supports for each leg may form acute angles with one another and they may be extended by screwed connections. A device carried by the load may control the rhythm of operation of the legs.

Title: Regenerable platinum-containing catalyst
IPC: C07C5/27
Filed: 1961-10-17
Abstract: A catalyst for the conversion of hydrocarbons consists of composite masses, each of the masses comprising a physical mixture of particles of alumina upon which is deposited platinum and of particles of a calcined silica-alumina cracking component, the alumina and platinum deposited thereon comprising from about 10-90% by weight of the final catalyst, the platinum on the alumina comprising from about 0,1-2,5% by weight of the final catalyst and the SiO2-Al2O3 cracking component being characterized by having an Al2O3 content of from 7-50% and at least one of manganese oxide, sulphide or sulphate deposited on the SiO2-Al2O3 cracking component, the Mn of the Mn compound being in an amount ranging from 0,25-1% by weight of the SiO2-Al2O3 cracking component.  The catalyst particles may take the form of extruded shapes, e.g. rods or pellets.  Platinum may be deposited on any commercially available Al2O3, e.g. chi, gamma or eta-Al2O3. Alternatively Pt may be deposited on an aluminium hydrate which is subsequently converted to Al2O3 by calcination.  Deposition of Pt may be effected from H2PtCl6, platinous or platinic tetrammino chloride or hydroxide, platinic chloride, chloroplatinous acid or ammonium chloroplatinate.  Mn is preferably deposited on the SiO2-Al2O3 component by impregnating with manganese chloride, nitrate, sulphate, acetate, benzoate, formate, and lactate, followed by calcination at any stage in the catalyst manufacture, and optionally with reduction by treatment with H2S1.  Regeneration of spent catalyst is effected by heating in an oxidizing atmosphere. Comparative examples describe the use of these catalysts for reforming petroleum hydrocarbons at 600-1000 DEG F., 50-1,000 p.s.i.g. and 0,75-2 vol./vol./hr with 5-15 mols. of hydrogen per mol. of charge or for isomerizing alkyl benzenes, e.g. xylenes, at 700-1,000 DEG F., 50-500 p.s.i.g. and 0,5-6 vol./vol./hr. with 1-20 mols. of hydrogen per mol. of charge.

Title: Organosilicon liquids
IPC: C08K5/098
Filed: 1959-11-04
Abstract: In making a liquid silioxane which is stable to oxygen, a mixture of (1) a liquid siloxane having Si-bonded hydrocarbon and/or halohydrocarbon radicals, and (2) an iron carboxylate containing from 4 to 18 C atoms, is heated in intimate contact with oxygen at a temperature above 200 DEG C. until the mixture will not form a precipitate when heated in the substantial absence of oxygen at a higher temperature.  The first step is preferably conducted at 230 DEG  to 315 DEG C. for a time (usually 2 to 4 hours) sufficient for the mixture to assume a deep reddish brown colour. The contacting with oxygen can be effected by bubbling oxygen through the liquid siloxane, or the mixture of the siloxane and iron salt can be caused to flow down a heated column packed with inert material while oxygen passes in the opposite direction.  The iron salts may be used as solutions in hydrocarbon solvents, the solvent being removed, if desired, prior to the oxygenation step. The term "oxygen" includes pure oxygen, air and mixtures of oxygen with air and inert gases, e.g. helium and argon.  Iron salts specified are the hexoate, 2-ethylhexoate, n-octoate, decoate, dodecoate, benzoate, phenyl-acetate, 3-methylcyclopentylbutyrate, cyclohexylcaproate, stearate and t-butylcyclohexylacetate, and are generally added in amount to provide from 0,006% to 0,03% of Fe calculated on the weight of the siloxane.  Examples are given.  Uses: as lubricants, greases, hydraulic fluids, heat transfer fluids and as heating baths for sterilizing surgical instruments.

Title: Improvements relating to the hydrofining of gas oil
Inventor: PIETSCH ROBERT BROOKE
IPC: F02B3/06
Filed: 1959-11-09
Abstract: Gas oil is solvent-extracted to remove aromatics and the extract, after being stripped free of solvent, is catalytically hydrofined at 600 DEG -900 DEG  F. and a pressure of 200-1600 p.s.i.g. and in the presence of hydrogen-rich gas supplied at rates of 200-6000 SCF/barrel of liquid oil feed.  The hydrofining, besides removing sulphur, converts the aromatics to naphthenes and the hydrofined extract is suitable for charging to a catalytic cracking unit. Solvent is also stripped from the raffinate, which may then be charged to a catalytic cracking unit.  Alternatively, the solvent-free raffinate and the hydrofined extract may be blended together and the blend may be catalytically cracked.  According to a modification, the solvent-free raffinate is further refined (e.g. by further solvent extraction, or by washing with acid or caustic alkali, or by hydrofining) to produce a diesel or jet fuel, while the hydrofined extract is recycled wholly or in part to the extraction step.  The initial solvent extraction may be effected with the aid of phenol, furfural or propane as solvent. The hydrofining catalyst may be cobalt molybdate (or cobalt oxide/molybdenum oxide) on alumina or molybdenum oxide on alumina, while the hydrogen-rich gas employed in the hydrofining step may be hydroformer tail gas.
