Filed: 1968-05-06
Abstract: 1,272,214. lso-α-acids. ALLIED BREWERIES Ltd. 5 May, 1969 [6 May, 1968], No. 21415/68. Heading C2C. [Also in Division C6] A process for preparing an iso-α-acid extract from lupulin substantially freed from hop residues involves subjecting the freed lupulin to treatment with an-aqueous alkaline solution at a pH of 8À5 to 9À5 to produce an aqueous extract containing iso-α-acids and separating unwanted solid vegetable matter therefrom. In a preferred procedure, the freed lupulin is first macerated and the macerated lupulin is treated by boiling it at a concentration of 10 g./litre for 30-45 minutes in aqueous sodium -carbonate solution at pH.9À0. The resulting extract may then be decanted from the sludge. Alternatively, the extract is acidified to pH 1À0 to precipitate the iso-α-acids, these are then settled with inert absorbent such as kieselguhr (or by centrifugation) and the settled solid matter is then extracted with hot sodium or potassium carbonate solution at pH 8-9.

Abstract: 766,471. Gas turbine plants. PARSONS & MARINE ENGINEERING TURBINE RESEARCH & DEVELOPMENT ASSOCIATION. July 22, 1954, No. 21437/54. Class 110(3). In a gas turbine plant in which a separate power turbine is provided, exhaust gases from the compressor-turbine 4 pass to the power turbine e through a duct d containing a valve n, and a by-pass f is provided across the power turbine, the by-pass containing a valve o which is interconnected with the valve n in the duct d. A heat exchanger k downstream of the power turbine e and a by-pass 8 around the heat exchanger are also provided, the heat exchanger by-pass containing a fixed orifice j and a valve p. For all power turbine loads from zero to full power, the combined flow through the power turbine and the power turbine by-pass remains constant and so does the rate of heat transfer in the heat exchanger. The valve p in the heat exchanger by-pass 8 may be interconnected with the two interconnected valves n and o. Alternatively, the valve p in the heat exchanger bypass may be a two-position valve controlled independently of the two interconnected valves n and o, the valve p in this embodiment being shut at full power and fully open at all other powers. Specification 697,137 is referred to.

Title: Improvements in or relating to the production of asphalt bitumen free from paraffin
IPC: C10C3/08
Filed: 1934-07-23
Abstract: Crude petroleum or residues containing asphalt and wax are dissolved in a solvent in which the soft asphalt is soluble, and the solution is cooled whereby the hard asphalt resins are precipitated in a granular form together with paraffin wax.  The mixture is filtered and the soft asphalt free from wax is recovered from the filtrate. Solvents specified are aliphatic ethers and esters such as the ethers of ethyl, isopropyl, amyl or butyl alcohols; and the esters of these with formic, acetic, propionic, butyric or capric acids.  Crude petroleum is freed from light oils and mixed with about an equal amount of an ester.  Low boiling esters are used with oils of low boiling point.  Heavy residues may be diluted with benzine or gas oil if necessary.  The solution is then chilled to -10 DEG  C., whereby paraffin wax separates as particles coated with hard asphalt resin and the precipitated substances are removed in a suction filter.  The exhaust gases from the suction pumps are washed with oil to recover the solvent vapours.  The filtrate is then distilled to yield a ductile bitumen suitable for road surfacing compositions, and a heavy lubricating oil; or the bitumen may be separated by precipitation by a solvent.  German Specification 241,528 is referred to.

Abstract: The invention comprises water-insoluble disperse dyes of formula <FORM:0952468/C3/1> wherein X is hydrogen, chlorine, bromine, cyano, trifluoromethyl or nitro, Y is hydrogen, chlorine, bromine, low molecular alkyl or acylamino, Z is hydrogen or low molecular alkoxy, R1 is low molecular alkyl, low molecular alkoxy-alkyl or low molecular acyloxyalkyl and R2 is low molecular acyloxyalkyl and wherein the term "acyl" denotes aliphatic monocarboxyclic acid residues and "low molecular" denotes that the alkyl and acyl residues contain from 1-4 carbon atoms.  The dyes are used to dye, pad and print polyester materials in blue and red shades and in admixture with other monoazo dyes in navy blue and black shades (see Division D1).  The dyes are prepared by diazotizing a suitable 2,4-dinitroaniline and coupling with a suitable N,N-disubstituted aniline or by acylating a dye of the above formula wherein R1 is low molecular alkyl, low molecular alkoxyalkyl or low molecular hydroxyalkyl and R2 is low molecular hydroxyalkyl with a functional derivative of an aliphatic monocarboxylic acid.  The preparation of the dyes is described in examples.ALSO:Stable dyeing preparations are prepared by 55 to 95 parts of one or more dyes of formula <FORM:0952468/D1-D2/1> wherein X is hydrogen, chlorine, bromine, cyano, trifluoromethyl or nitro, Z is hydrogen or low molecular alkoxy, R1 is low molecular alkyl, low molecular alkoxyalkyl or low molecular acyloxyalkyl, R2 is low molecular acyloxyalkyl and R3 is low molecular alkyl (see Division C4) and 45 to 5 parts of one or more dyes of formula <FORM:0952468/D1-D2/2> wherein V is hydrogen, chlorine or bromine, W is chlorine, bromine, cyano or trifluoromethyl and R4 is hydrogen, methyl, ethyl or chlorine and R1 is as defined above with one or more anioric dispersing agents or standardising agents. The term "acyl" denotes aliphatic mono-carboxylic acid residues and "low molecular" denotes that the alkyl and acyl residues contain 1-4 carbon atoms.  The dye mixtures give navy blue or black shades on polyester fibres.  In an Example 2, 4-dinitro-6-bromo-51-acetylamino-41-bis (acetoxyethyl)-amino-51-ethoxy-1, 11-azobenzene is ground with sodium sulphate, sodium dinaphthylmethanedisulphonate and sodium cetylsulphate to a fine powder, which is further admixed with corresponding preparations of the dyes 2-chloro-4-nitro-41-(N-acetoxyethyl-N-cyanoethyl)-amino-1, 11-azobenzene and 2, 6-dichloro-4-nitro-41-(N-acetoxyethyl-N-cyanoethyl)-amino-1, 11-azobenzene.  The mixture is pasted with water and added to a dyebath containing lauryl sulphate.  Polyester fibre is entered in the bath at 40-50 DEG C., the bath heated slowly and dyeing continued for 1-2 hours at 95-100 DEG C. in the presence of an emulsion of a chlorbbenzene in water.  A black dyeing is obtained.  Further examples are specified.

Abstract: 390,702. Fluid-actuated valves. SULZER FR’RES SOC. ANON., Winterthur, Switzerland. Aug. 8, 1932, No. 22192. Convention date, Aug. 26, 1931. [Class 135.] Valves controlled by pilot or relay valves.- Valves controlling the water or fuel supply to a steam boiler, or the pressure or any other working valve of the boiler are actuated by servomotor devices operated not only in accordance with the temperature or pressure in the boiler, but also in accordance with the rate of change of the temperature or pressure. The expansion and contraction of a bent pipe 32 forming part of the boiler are communicated to a piston 12 in a cylinder 11 supplied with pressure fluid and having its ends connected together through a throttling device 14. The pressure in the pipe 16 leading from the cylinder is a measure of the rate of movement of the piston and of the rate of change of the temperature in the boiler. The expansion and contraction of another bent pipe 33 forming part of the boiler are communicated through a spring 36 to the piston 37 of a servomotor. The pressure of the fluid in the pipe 42 leading from the servomotor varies directly with the temperature in the boiler, and may operate the feed or fuel valve, and it may also act in conjunction with the pressure in the pipe 16 on the piston 46 of a servomotor through which pressure fluid is supplied to the device operating the feed or fuel valve. The bent pipe 32 may be connected to the piston 12 through a floating lever servomotor. A single bent pipe 65, Fig. 4, may be used to produce both the pressure impulse varying directly with the temperature &c. and the impulse varying with the rate of change of temperature &c. The pressure fluid from the servomotor 37 actuates the sliding valve 18 of a further servomotor in which a piston 24 actuating the feed &c. valve is acted upon on its under side by a second pressure fluid. The upper side of the piston 24 is supplied with a third pressure fluid, which enters and escapes from the cylinder 23 through a throttling device 71. The pressure in the pipe 68 leading from the throttling device, which pressure varies with the rate of change of the temperature in the boiler, is communicated through a servomotor to a rod 78 actuating the feed &c. valve. A rod 25 on the piston 24 and the rod 78 may be joined by a lever 90 to which is connected a rod operating the valve in accordance with the combined pressure impulses.
