Title: Method and apparatus for the production for liquid malt extracts
IPC: C12C1/18
Filed: 1971-08-13
Abstract: 1370482 Producing wort MALZFABRIK W SCHROER & SOHN KG 13 Aug 1971 [13 Aug 1970 9 Oct 1970] 38115/71 Heading C6E [Also in Divisions A2 and B1] Liquid malt extracts are obtained by passing a stream of aqueous liquid through germinated and rough-ground cereal grains in a series of towers provided with tangential inlets associated with heaters/coolers, whereby the temperature and density of the liquid may be controlled automatically with the aid of thermocouples and hydrometers through diversion of part of the liquid flow. The aqueous liquid passes sequentially through a washing-out zone (one tower length), a pre-saccharification zone (one to 1¢ tower lengths) and a saccharification and extraction zone (1 to 2 tower lengths), represented in Fig.1 by the towers V to II, during which the temperature of the liquid falls progressively within the range 85‹ to 60‹C and its S.G. increases from 1À00 up to say, 1À15. Light-coloured extracts can be produced by working at relatively low temperatures under sub-atmospheric pressure. Tower I in the Fig. is being emptied of spent grains and recharged. Fig.7 depicts one form of tower having a broadened upper part. The liquid extract, containing 30g solids per 100g of solution, may be boiled and clarified, and freeze-dried to a powdery solid. Caramelized extracts of a light or dark tone can be prepared by adjustment of the temperature.

Title: Method of producing weather-resistant pellets
IPC: C22B1/242
Filed: 1959-11-11
Abstract: Weather-resistant pellets of fine-grained materials for roasting and/or sintering, such as flotation pyrites, zinc blende, antimony sulphides, or platinum concentrates, are produced by pelletising the materials with sulphur or a material containing elementary sulphur, such as waste sulphur rich in ash and/or bitumen, with or without a heat-resistant binding agent such as bentonite.  Preferably finely ground sulphur (under 0,2 mm grain size) is added, or in place of sulphur and heat-resistant binding agents an exhausted gas purification compound or sulphur earths may be used.  After pelletisation, the mixture is dried, then heated to above the melting-point of sulphur (e.g. between 125 DEG  and 130 DEG C.) and finally cooled.

Title: Acrylonitrile and methacrylonitrile copolymers
IPC: C08F28/00
Filed: 1960-11-04
Abstract: Acrylonitrile and/or methacrylonitrile are copolymerized with vinyl sulphonic acid, a substituted vinyl sulphonic acid or a water-soluble salt thereof in an aqueous medium at a temperature of at least 20 DEG C. under conditions such that: (a) the vinyl sulphonic acid or salt is initially present in an amount of at least 30% of the total weight of monomers, (b) the initial total monomer concentration is from 45 to 70% of the weight of the reaction mixture, (c) water is added during the polymerization so that thorough mixing is possible and (d) the water content at the end of the polymerization does not exceed 75% by weight of the reaction mixture.  Additional monomers may be present during the reaction, e.g. acrylic and methacrylic acids and amides, styrene sulphonic acid and vinyl pyrrolidone.  Polymerization catalysts are employed to assist the reaction, e.g. diacyl peroxides, mixed diacyl peroxides, alkyl peroxides and hydroperoxides, ketone peroxides, dialkyl percarbonates, hydrogen peroxide and alkali metal and ammonium persulphates, percarbonates, perborates and persulphates.  There may also be used as catalysts redox systems consisting of a per-compound and a reducing agent, e.g. a bisulphite, pyrosulphite, thiosulphate or formaldehyde sulphoxylate.  The aqueous medium may contain an emulsifier and preferably has a pH value of from 3 to 6.  The polymerization is preferably carried out by initiating polymerization in a portion of the monomer-catalyst-water mixture and then adding the remainder of the mixture as the reaction proceeds.  The resulting copolymers are soluble in water when the content of vinyl sulphonic acid in the copolymer exceeds about 65% by weight, and may be used as textile finishing agents, thickening agents and soil-improving agents.  Copolymers containing 30 to 50% of vinyl sulphonic acid may be used as additives to spinning solutions of polyacrylonitrile.  In an Example (6) of this latter process an aqueous dispersion of a 95/5 copolymer of acrylonitrile and methyl acrylate is mixed with an aqueous dispersion of a 50/50 copolymer of acrylonitrile and sodium vinyl sulphonate, the mixture is filtered and the resulting polymeric material is dissolved in dimethyl formamide to provide a spinning solution from which fibres of good dyeability are spun.

Title: Improved means for controlling the transmission of electric energy through waveguide systems
Inventor: MARTIN RONALD CYRIL
IPC: H01P1/12
Filed: 1959-11-13
Abstract: 963,536. Waveguide Faraday rotators. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 11, 1960 [Nov. -13, 1959], No. 38639/59. Heading H1W. The solenoidal magnetic field of a waveguide gyromagnetic device is supplemented by an additional field at an acute angle to the main field. In the Faraday rotator shown, a ferrite element MC, axially magnetized by a coil CL, effects a 90 degree rotation of the plane of polarization of propagated wave energy whereby coupling is established between two rectangular waveguides A, B (shown misaligned) whose corresponding cross-sectional axes lie at right angles to each other. An angularly adjustable permanent magnet PM provides a supplementary field lying at an acute angle to the axial field. The axial component of the supplementary field may be sufficient to cancel the remanence of the ferrite element MC, thus ensuring that when the coil CL is switched off, the waveguides A, B are completely isolated from each other. The magnet PM may also be used to correct for errors in the manufacture and assembly of the rotator. Specification 920,065 is referred to.

Title: Method of recovering ammonia gas from an aqueous solution containing ammonia and carbon dioxide
IPC: C07C273/04
Filed: 1964-09-23
Abstract: In the manufacture of nitriles by ammoxidation of hydrocarbons with molecular O2 in the presence of NH3, the off-gas containing NH3 and CO2 is scrubbed with water, and air and/or O2 is passed through the solution to desorb NH3, the resulting mixture of NH3, air and/or O2 being recycled for further ammoxidation of hydrocarbons. Reference is made to the production of benzonitrile from toluene and of phthalonitriles from xylene.ALSO:<PICT:1072293/C1/1> Ammonia is recovered from an aqueous solution containing NH3 and CO2, the molar ratio of NH3: CO2 being, more than two, by passing through the solution a desorption gas, which does not react with NH3 and CO2, at a temperature below 60 DEG  C. and above the freezing point of said solution and thus desorbing NH3 gas free from CO2.  In one embodiment, an NH3/CO2 solution produced by scrubbing a gaseous NH3 / CO2 mixture formed in urea synthesis, or in the manufacture of nitriles from hydrocarbons by ammoxidation, is fed through line 6 into top plate 3 of desorption column 1 and is contacted with ascending desorption gas, e.g. O2 or N2, or a mixture of these such as air, thereby desorbing part of its NH3 content.  The desorbed NH3 and desorption gas leave by line 7 and may be recycled to the ammoxidation reactor.  The NH3-depleted solution descends via the plates below, e.g. bubble cap plates to the bottom of the column and is removed by line 4.  The whole or part of the solution on a plate may be removed from the column and heated in a heater 2 to maintain the desired column temperature, or alternatively an interior heater is provided. The NH3/CO2 solution and desorption gas may be pre-heated. Column pressure is usually atmospheric but can be elevated or reduced. A counter current pipe system and an agitation mixing system are other desorption means specified.

Abstract: 1486429 Supplying tyre components to building drums GENERAL TIRE & RUBBER CO 16 Sept 1974 [16 Oct 1973] 40232/74 Heading B7C Apparatus for supplying a belt or breaker strip to a tyre building drum comprises a belt guide roll 65 defining a belt strip receiving groove 92 of a width x corresponding to the width of the strip, a first drive ring 84 rotatable with the roll 65, a second drive ring 85 rotatable with the drum, the rings having a ratio of diameters substantially equal to the ratio of diameters of the groove base and the drum whereby the belt guide roll is driven by rotation of the building drum, when the rings are in frictional engagement, at substantially the same surface velocity as the surface velocity of the drum during application of the belt strip. As illustrated two belt guide rolls 63, 65 are provided and are mounted in a frame 83 which is advanced towards the drum (not shown) by manual or automatic actuation of air cylinder 75. During such motion an air clutch associated with roller 61 is engaged to brake the chain 68 so that the guide rolls roll along the strip. At the end of such advance a switch is operated to disengage the air clutch and ring 84 of roll 65 is now in frictional engagement with ring 85. An air motor 67 assists in reducing to a virtually negligible amount the friction force and inertia to be overcome in rollers 58, 61 and rolls 63, 65 by the drive to be imparted to roll 65 by the drum. After spotting of the belt strip on the drum, the latter is actuated and the strip is advanced by rollers 58, 61, 63 and 65, until the drum has completed one revolution. The strip is cut and the ends of the cut-off strip portion is manually stitched. The apparatus further comprises a strip supply roll driven by electric motor 41 which is controlled by a potentiometer 51 mechanically controlled by a dancer roller 45 journalled on a pivoted arm 46. Interruption of light beam from a source 86 by roller 45 causes the motor 41 to stop. A second belt strip supply apparatus, substantially identical to that disclosed above is also mounted in frame 14/15 which frame is movable on rails 18, 19 to position the two apparatuses sequentially in alignment with the building drum.
