Title: An improvement in a method and an apparatus for sizing of discrete particles in a fluid medium
Inventor: HUKKI RISTO TAPANI
IPC: B03B5/34
Filed: 1966-02-17
Abstract: 1,134,864. Classification of solids. INSINOORITOIMISTO ENG., BUREAU R.T. HUKKI. 17 Feb., 1966, No..7042/66. Headings B2H and B2P. A multiple step, quality control section for connection to a pneumatic or hydraulic separator comprises an outer shell made up of coaxial,; superimposed, cylindrical rings 11 -Fig. 4, each having a skirt-like inward extension 13, an inner core made up of coaxial, superimposed, conical core pieces 5 each having an inner conical extension 7, Fig. 2, provided with one or more slots 9 communicating with a central opening 8, and a top piece 1 having a conical base portion and an upper tubular portion 3. The rings 11 are clamped between flanges 18, 19 and each ring may be provided with one or more tangential inlet means 14 for the wash medium opening in the annular space below the extension 13. The core pieces 5 are each provided with one or more lugs 10 and are supported by the lugs 10 on the lowermost core piece resting against the extension 13 of the lowermost ring 11 and by one or more lugs 4 on the top piece 1 engaging under the extension 13 of the uppermost ring 11. The parts 1, 5 and 13 are preferably made of rubber. The control section may be connected to the seperator by a flexible joint so as to be vibrated. In operation, the rotating coarse fraction from the separator enters in helical manner into the downward leading, zig-zagging space between the rings 11 and the core pieces 5 and spreads out into skirt-like annular layers. Wash medium admitted through the inlets 14 is forced across the layers and carries with it fines towards inclined channels 15, formed by the slots 9 in one core piece 5 with an adjacent core piece, and discharges into the central tube 16 constituted by the openings 8 in the core pieces 5 and the tube 3. The coarse fraction resisting the washing action of the medium continues its helical motion and discharges at the bottom of the section. In a hydraulic classifier 22, Fig. 5, equipped with a quality control section 23 for the coarse fraction, a suspension of solids to be classified is fed via a pipe 25 and a tube 26 on to a distributor plate 28 mounted on a rotating shaft 27 which also carries an impeller 30 and an ejector 31. The suspension is whirled by the impeller 30, the fine fraction discharging upwards via whirl-arresting vanes 34 into a launder 36. The coarse fraction passes downwards into the section 23 where it is washed by water fed from a tank 37 via control valves 30 and the inlet pipes 14. Wash water and entrained fines pass up the tube 16 and the impeller hollow shaft 29 and are sprayed by the ejector 31 below the curtain of in-coming suspension and are discharged upwardly with the fine fraction. The washed coarse fraction enters a cone 32 and is discharged via a valve 33.

Title: Method of improvement of product distribution in hydrocarbon catalytic cracking processes
Inventor: LEUM LEONARD NORMAN
IPC: B01J21/20
Filed: 1961-02-27
Abstract: In the catalytic cracking of hydrocarbons using a silica-alumina cracking catalyst, at least part of the catalyst is removed from the process and contacted in an aqueous medium at a pH of 2-4,5 with a cation exchange resin in the acid form then separated and returned to the process.  Coke-forming and gas-forming metal contaminants are thereby removed from the catalyst.  The catalyst may be synthetic, containing 7-30% of alumina, semi-synthetic, being a natural or acid-treated clay to which silica or alumina is added to give an alumina content of 30-35%, or a natural clay which may have been acid-treated or to which alumina may have been added to give an alumina content of 15-50%.  The amount of catalyst withdrawn and treated per day may be 5-15% of the total when cracking gas oil or 15-40% when cracking residual materials.  The catalyst may form 10-40% by weight of the catalyst-water mixture and the ratio of catalyst to resin may be 0,25-1 g. of catalyst per ml. of wet resin or 0,5-2 g. per g. of dry resin.  Temperatures of 75 DEG F. up to the disintegration temperature of the resin which may be 250 DEG -260 DEG F. Longer contact times are necessary at lower temperatures; generally 1-24 hours are necessary.  Various acids may be used to control the pH, e.g. sulphuric, hydrochloric, oxalic, citric or tartaric.  Specified cation exchange resins are Amberlite IR-120 and Permutit-Q (both Registered Trade Marks).

Title: Pulse counter
IPC: H03K21/00
Filed: 1973-02-13
Abstract: 1397874 Counters INSTITUT ELEKTRONIKI I VYCHISLITELNOI TEKHNIKI AKADEMII NAUK LATVIISKOI SSR 13 Feb 1973 7059/73 Heading G4A An m-phase pulse counter comprises m chains 1, 2 of n logic gates 3-7 so interconnected that the gates of each chain have n stable states and has the n inputs 8-12 of each chain connected to the n outputs 13-17 of the other chain(s) by way of m sets of n AND-gates 18-27 the second inputs of the AND gates being interconnected to form the m phase inputs 28, 29. In Fig. 1, each chain 1,2 comprises five fourinput NOR-gates 3-7; the output of each NOR-gate is connected to the inputs of two others and the inputs 8-12 of the chain are each connected to two NOR-gates; if one of n fivebit binary words is applied to terminals 8-12 the chain assumes a state dependent on the word and delivers a different five-bit word at its output 13-17; this output is maintained when the input word disappears. The two phase input terminals 28, 29 are marked alternately; therefore the sets of AND-gates 18-22 and 23-27 alternately apply the output word of one chain to the input of the other to change the state of the latter. The two chains therefore count sequentially through their five states. Thus for a two phase input the counter delivers a five phase output at each set of terminals 13-17 or a ten phase output if both sets are taken. If the input terminals 28, 29 are connected respectively to the input and output of an inverter fed with a single phase signal then a signal at one fifth the frequency may be taken from any one of terminals 13-17; several such stages can be cascaded to form a multistage counter. It is stated that the inputs of the gates in each chain must be coupled to the outputs of s other gates in that chain where 2 # s # n-3.

Title: A process for the production of threads by the viscose spinning process
IPC: D01F2/10
Filed: 1957-03-04
Abstract: Threads are produced by spinning viscose in an acid bath containing more than 2.5 per cent by weight of zinc sulphate and 0.2-5 per cent by weight of formaldehyde, there being added to the viscose, in a proportion of 0.5-5 per cent by weight, calculated on the cellulose content of the viscose, and/or to the spinning bath, in a proportion of 0.5-5 g/kg. of spinning bath, one of the following compounds: (1) a polyalkylene glycol, e.g. polyethyleneglycol; (2) a reaction product of a polyalkyleneglycol with an amine, e.g. a fatty amine, an alcohol, e.g. a fatty alcohol, a fatty acid or an aromatic acid, (3) an aliphatic or aromatic monoamine, diamine or other polyamine; (4) a quaternary ammonium compound, e.g. a quaternary ammonium base or an oxyethylation product thereof; (5) a mono- or di-thio carbamate; (6) an imidazole, e.g. 2-mercapto-benzimidazole; or (7) a thiazole, e.g. mercaptothiazole.  The spinning bath may contain sodium sulphate and the relative proportions of the salts contained in the spinning bath may be so adjusted that the sodium sulphate content is lowered with increasing zinc sulphate content, a sodium sulphate content of 17 per cent by weight corresponding to a zinc sulphate content of 4 per cent by weight and a sodium sulphate content of 12 to 13 per cent by weight corresponding to a zinc sulphate content of 8 per cent by weight. The thread is preferably guided through the spinning bath as far as possible without tension and subjected to a stretching process in a second bath, containing about 0.2-3 per cent by weight of sulphuric acid and small proportions of sodium and zinc sulphates, maintained at a temperature higher than 80 DEG  C.  When added to the viscose, the additives are preferably introduced in the mixer, although they may be added during the breaking up of the fibres or during the sulphidizing operation, or just before spinning.

Filed: 1920-03-10
Abstract: 168,922. Pino, G. March 10, 1920. Hulls; salvage vessels; oil-carrying vessels.-A submersible salvage vessel with an open-bottomed but otherw i s e air-tight chamber adapted to be lowered over a sunken ship in the manner of a diving-bell to raise the same is provided with extensible towers having tops which float when the vessel is submerged, and apparatus within the chamber to right the sunken ship. The vessel consists of a tunnel-like structure, Figs. 1, 3 and 5, having side walls 4, a fore wall 5, and a hinged watertight door 6 at the stern. 'The side walls are formed with water-tight compartments 17, reinforced by bulkheads, and containing solid ballast 20. Outside these compartments are water ballast compartments 30 with longitudinal and transverse bulkheads 31, and in the roof structure are located chambers 65 to give increased stability. Towers 21 contain motors, winches and air-compressors, and quarters for the crew. The towers are telescopic and are extended by means of a shaft 22, Fig. 3, actuated by a motor 23. Passages 27 give access to the interior of the tunnel so that work may be carried out on the sunken ship. The compressors in the towers are connected by pipes with the compartments 30 and with the interior of the tunnel. At the stern of the compartments 30 are located compartments containing motors driving propellers 35, rudders 38 being also provided. Rams 42, Figs. 3 and 5, consisting of two cylinders, the inner of which is slidable in the outer by means of a rack and screw and carries at its outer end a bearing plate, are provided in the walls of the tunnel to bring the sunken ship into an upright position. Resilient fenders 43 are also provided. In raising a ship which is only slightly damaged, the apparatus is lowered over the ship, and pipes 44 reaching to the bottom of the ship placed in position. Compressed air is then forced into the tunnel, expelling the water from the ship, which is then repaired. The water is then discharged from the compartments 30, and the whole apparatus rises to the surface, the salvaged ship floating on the surface of the water in the tunnel, and being then floated out through the door 6. For operating at greater depths, the towers 21 are provided with floating tops 45, which remain on the surface when the towers are submerged, being connected thereto by cables 46 wound on winches 47 and 51 in the towers and floats respectively. To control the submersion of the vessel, weights 53, normally housed in recesses 56, are lowered to the bottom by cables 57 running over winches 58. Figs. 6 and 7 show a modified form of vessel having only two lateral water-tight compartments 67, 68, with solid ballast 69 located at the centre, and divided into three chambers by inclined bulkheads 73, 74. The middle chamber 78 is emptied of water to raise the vessel to the surface, while additional lift to enable the salved ship to be floated out is obtained by emptying the other chambers 79, 80.
