Filed: 1959-10-23
Abstract: Sulphur is produced from a gaseous mixture comprising hydrogen sulphide, one or more hydrocarbons in a "carbon index" concentration of less than 36%, and optionally one or more inorganic and/or organic sulphur compounds by admixing with oxygen in the pure state or in admixture, e.g. as air or oxygen enriched air in an amount stoichiometrically equivalent to the total amount of carbon and hydrogen in the gaseous mixture for combustion to carbon dioxide and water, passing the oxygen-containing gas through a first catalyst stage containing alumina impregnated with 0,1-2,0%, e.g. 0,5%, of platinum arranged in a plurality of spaced layers, e.g. 4, with intermediate cooling so as to effect substantially complete consumption of the oxygen at a progressively decreasing reaction temperature in the range of 300 DEG -950 DEG C., recovering any sulphur which condenses in the first stage, passing the effluent gas through a second catalyst stage containing alumina impregnated with 0,05-1,2% of one or more of platinum, nickel, cobalt, copper, and chromium, preferably nickel-copper-chromium, so as to convert sulphur dioxide produced during the first stage to sulphur by reaction with unoxidized hydrogen sulphide at a temperature in the range of 250 DEG -600 DEG C., recovering any sulphur condensed in the second stage, and recovering sulphur from the effluent gas.  The gas may flow through the first and second catalyst stages at a rate of 5,000-15,000 times the volume of catalyst per hour.

Title: Process for dyeing cellulosic textile materials
Inventor: RIEDERER HANS
IPC: D06P3/66
Filed: 1961-09-25
Abstract: Cellulose textile materials are dyed by the so-called pad-dwell process in which the material is impregnated with a liquor contain an alkali, a reducing agent and a reactive vat dyestuff and thereafter maintained in the wet or moist state substantially without the application of heat.  The reactive vat dyestuffs are preferably water-soluble and may be from the anthraquinone series, for example, those which contain an unmodified 9:10-dioxo-anthracene ring, a plurality of carbocyclic or heterocyclic systems or consist of a plurality of anthraquinone units, also dyes of the perylene tetracarboxylic acid, naphthalene tetracarboxylic acid or pyrene-quinone series or indigoid vat dyestuffs.  A long list of suitable reactive groupings is given preferred of which are the ethyleneimino, acrylic acid vinyl sulphone and halogenated triazinyl groups.  The dyestuff is preferably applied by padding from a padding liquor which contains as alkali an alkaline earth metal hydroxide, an alkali metal metasilicate, trisodium phosphate, sodium or potassium carbonate or preferably sodium or potassium hydroxide.  The reducing agent may be sodium hydrosulphite, thiourea dioxide, sodium sulphide, sodium hydrosulphide or glucose.  The alkali and the reducing agent may be applied after the dyestuff in a separate padding operation. The fixation of the dyestuff may be effected by covering a roll of the impregnated material with a plastic foil and maintaining it at 10-40 DEG C. for 2-48 hours, if desired, while being slowly rotated. Soaping, rinsing and re-oxidising finishing treatments may be employed.  A number of examples of dyeing fabrics of viscose, cotton and linen fibres are given in which a number of dyestuffs are employed.

Title: Static time-lag overcurrent relay
IPC: H02H3/093
Filed: 1963-08-30
Abstract: 1,047,940. Protective arrangements. ALLM€NNA SVENSKA ELEKTRISKA A.B. Aug. 30, 1963 [Sept. 4, 1962], No. 34357/63. Heading H2K. When the current J 1  proportional to that in a protected circuit exceeds a reference current Jr a capacitor C in a static inverse time delay overcurrent relay arrangement is charged by the difference between the currents. In the arrangement shown, the reference current Jr flows through a diode V 3  and resistors R 1 , R 2  from an auxiliary source U 2 , a diode V 2  serving to keep this current constant. The current J 1  is obtained through a current transformer T and rectifier bridge L. Since the diode V 3  is conducting, it provides a path for the current J 1  until that current exceeds Jr. Thereafter the difference J 2  between these currents flows to capacitor C and resistor R. When the capacitor has been sufficiently charged a diode V 4  breaks down and a relay E is energized. This relay closes contacts E a  to permit the rapid discharge of the capacitor and operates further contacts (not shown) to cause the opening of a circuitbreaker. The relay E may be a static device, e.g. a transistor.

Abstract: 388,153. Filters. MOTOR IMPROVEMENTS, Inc., 365, Frelinghuysen Avenue, Newark, New Jersey, U.S.A.-(Assignees of Liddell, R. P. F. ; 291, Mt. Kemble Avenue, and Williams, L. W.; 297, Mt. Kemble Avenue, Morristown, New Jersey, U.S.A.) Dec. 11, 1931, No. 34396. Convention date, Dec. 11, 1930. [Class 46.] A filter comprising a casing divided into inlet and outlet sections bv a stationary filtering unit is provided with means for cleansing the filter by forcing filtered fluid reversely through the filtering unit without change in the contents of the casing, there being a connection between the inlet and outlet sections additional to the connection afforded by the filtering unit itself. The oil filter shown comprises a shell 11 connected by an annular nut 12 to a base 10 formed with an inlet 27, an outlet 28, and a central well 10a. A cup 13 of the shape shown fits into the well 10a and is furnished with a tube 14 resting on inwardly bent tongues 15. A fluted drum 16 extends into the cup 13 with the tube 14 passing through a serrated opening in it and fitting into an offset part 17 at the top. The cylindrical filtering unit 18 surrounds the fluted drum 16. It consists of a helically wound thin metal ribbon provided with spacing ribs at intervals and preformed with definite curvature. A sleeve 20 provided with a handle slides on a central tube 19 and carries a pump plunger 23 fitting the tube 14. The plunger is normally locked in the position shown by arms on the sleeve 20 passing under the tongues 15. Apertures 25, 26 are formed in the upper part of the tube 14 and sleeve 20 respectively. The oil passing through the filter unit 18 passes along the flutes of the drum 16, through the serrated opening round the tube 14, through the aperture 25 into the tube 14, then through aperture 26 and tube 19 to the outlet 28. A reverse flow is caused by pulling up the sleeve 20 and plunger 23, thus reducing the capacity of the outlet section of the casing and increasing the capacity of the inlet section, unfiltered oil passing into the tube 14 through the opening formed by bending up the tongues 15. In a modification the inlet and outlet are in a head at the top of the casing and the central tube and sleeve are dispensed with, the pump plunger being carried by a rod provided with an operating handle.

Abstract: 923,030. Wells. OTIS ENGINEERING CORPORATION. Sept. 27, 1961, No. 34568/61. Class 85. A pipe hangar or anchor 13 comprises a tubular body 18a, 18b, a sleeve 24 slidable on the body, slips 30 carried by the sleeve, an expander 34 on the body adapted to engage the slips with a pipe 12 when the sleeve is moved upwardly relative to the expander, interengaging means on the slips and expander to retract the slips on downward movement of the sleeve on the body, a chamber 49 between the sleeve and body and adapted to be filled with fluid to prevent the upward movement of the sleeve, and a port 56 openable to release fluid from the chamber to permit the upward movement. The hangar is incorporated in a pipe string 10 together with packings 63, 62 and a lower packer (not shown), the chamber is filled with grease which is retained by a frangible plug 57, and the assembly is lowered to the desired depth in the casing 12. The lower packer is set, the string tensioned and a weight dropped down the string to break the plug. Fluid introduced into the string passes through apertures 15 so that packing 63 is urged against the sleeve 24 which moves upwardly to set the slips. The assembly is released by a tool 71 which is engaged with threads 70, and has a check valve 78 opposite the port 56 and flanked by seals 75, 77. A valve 80 is dropped into the tool, and fluid is pumped down through the tool through the valves 80, 78 into the chamber to force the sleeve downwardly and disengage the slips. The string 10 is then manipulated to release the lower packer. In modified hangars the sleeve is moved upwardly to set the slips by a spring or by a pneumatic cushion instead of by fluid introduced down the string. In a further modification the sleeve has a drag member and the slips are set by lowering the string.
