The invention relates to isolation of an Aspergillus gene encoding rhamnogalacturonase (RG-ase) and the construction of recombinant Aspergillus strains with overexpression of RG-ase. These strains can be used for the commercial production of RG-ase. RG-ase is an important enzyme in processes requiring the degradation and/or modification of pectin or modification of pectin-containing vegetable or plant cell wall material. RG-ase may be used in various applications, including the processing of fru…

The invention concerns derivatives of the formula wherein n is 1, 2 or 3 and each R.sup.2 is independently halogeno; and R.sup.1 is amino-(2-4C)alkylamino, (1-4C)alkylamino, (1-4C)alkylamino-(2-4C)alkylamino,di-[(1-4C)alkyl]amino-(2-4C) alkylamino, pyrrolidin-1-yl-(2-4C)alkylamino, piperidino-(2-4C)alkylamino, morpholino-(2-4C)alkylamino, piperazin-1-yl-(2-4C)alkylamino, or 4-(1-4C) alkylpiperazin-1-yl-(2-4C)alkylamino, or pharmaceutically acceptable salts thereof; processes for their preparatio…

A method of characterizing a test sample of genomic DNA which method comprises contacting the test sample with type specific primer to prime selectively, within a telomere repeat array, internal repeat units of that type, and extending the type specific primers in the presence of appropriate nucleoside triphosphates and an agent for polymerization thereof to produce a set of amplification products extending from the internal repeat units of that type to at least the end of the telomere repeat ar…

The novel specific immunophilin ligands of the general formula I have an antiasthmatic and immunosuppressive action and are suitable for the preparation of drugs. ##STR1##

A valve is provided having an inlet and a number of outlets any one of the outlets being closable while allowing flow through the others, there being no stagnant zones in the valve when liquid passes through all outlets.

An antenna system for reducing co-channel interference in a signal receiving network, said system comprising; at least four logarithmically periodic antenna elements having corresponding points disposed in a common plane, a first two of said antenna elements also disposed within a horizontal plane, the remaining two of said antenna elements also disposed within a vertical plane, said first two elements being substantially equal first distances from the line of intersection of said horizontal and…

A method of casting a line and fly when fishing by means of a fishing rod having a detachable handle, the detachable handle having a reel attached thereto, comprising the steps of separating the detachable handle carrying the reel from the rest of the rod, and holding the detachable handle with the reel in one hand and the rest of the rod in the other hand, the reel being restrained to prevent rotation thereof, making a back cast, bringing the hands near each other with the reel restrained, rele…

A propeller blade of the kind having a light wood body, a root of harder wood, and a metal ferrule connecting the root to the propeller hub, is reduced in bulk without loss in mechanical strength or efficiency by using a special wood/resin lamination for the root and covering the whole of the body with a skin composed of a resin reinforced by one or more layers of fiber, e.g., woven glass fiber fabric. The application of a metal protection to the leading edge of the blade and the retention of th…

A process for producing a vesicular photographic image while minimizing shrinkage of the backing layer upon which the vesicular photographic material is coated. The coating contains, in addition to sensitizer, a dye or pigment which can produce heat on exposure to non-actinic light. The material is exposed, image wise, to actinic light and then exposed uniformly to non-actinic light which is absorbed by the dye or pigment to heat the material and produce an image. Since the dye or pigment is not…

Methods and apparatus are described for discouraging the formation of unwanted lumps which tend to form when preparing mixes of certain components, especially of fibres and a slurry. A mixing agitator, which is moved relative to the mix, is arranged to have a further motion such as by being free to rotate, or by being rotated, in response to conditions within the mix.
