The said article, solid or hollow, comprises a core 1 and an outer sheath 2 which surrounds at least once the said core and firmly adheres thereto. The process consists: in conforming at least one strip of flexible material around a stationary hollow element 20 to form the sheath 2; in continuously driving the sheath 2 thus formed towards the end of the stationary hollow element; and in continuous...

In the treatment of mixed waste such as refuse for the separate recovery of paper and plastics sheet material scrap, in particular in recycling plants, a pre-sorted fraction containing paper and plastics sheet material scrap is treated in a pulper (1), the paper pulp suspension thus obtained is withdrawn via screens and paper fibre recovered and the screening residue containing the plastics sheet ...

The present invention relates to anthracycline derivatives of the general formula I where R represents the group -(CH2)mH in which m denotes 0 or an integer of 1 to 6, or the group -(CH2)nCOOH in which n denotes 0 or an integer of 1 to 10, and a process for their preparation. The compounds of the invention exhibit high antitumor activity and good water solubility and can, therefore, be used...

Novel single-chain hybrid plasminogen activators having an amino acid sequence composed of at least two subsequences corresponding in amino acid identity and number to subsequences of human t-PA and of human u-PA, and mutants thereof in which at least one of the N-glycosylation sites is modified such that glycosylation cannot take place at these sites exhibit valuable pharmacological properties. T...

An excavating tooth assembly is described including an adapter (22), a point (21) equipped with rearwardly projecting tongues (28), and locking means including a vertical pin (32) external of the adapter nose (23) held in place by a shrouded spring loaded plug (41) disposed perpendicularly to the line of the mounting point (21) on the adapter (22), the pin (32) having arcuate front (34) and back (...

A disposable article for one step interim cleaning of hard surfaces comprises a non-woven substrate, carrying an aqueous cleaning composition loaded onto the substrate at a level less than about 85%, preferably less than 75%, of its maximum absorbence capacity. The aqueous composition comprises: optionally, one or more nonionic surfactants, one or more anionic surfactants or mixture of nonionic an...

The arrangement consists of two pref. plate-shaped cable end pieces (8) which partially locate and centre a casing around the union. The pieces are joined to one another by at least two long components (9,10,11). The cable end pieces have central holes for fixation of contact units (12) which, apart from maintaining galvanic connection with the cable reinforcement (13), transmit traction forces fr...

In the exhaust gas pipe thrust waves move forwards and backwards as the result of reflection as the area of the pipe alters. The timing of the wave movement is controlled by the length of the pipe, and also by the speed of sound determined inter alia, by temp. and the gas constant. To increase effect, it is desirable to increase the length of the pipe (17) at low speed. Thus by the injection (24) ...

A sufficient quantity of phoscarnet acid (or a conceivable salt) is administered. Pref. the trisodium salt is used.

The rudder surface or blade (2') is normally in a collapsed condition, but when the control signal is received it adopts at least one extended position in which it is angularly adjusted in relation to the flight direction of the airborne unit of which it forms part. The blade can be made to extend to varying degree dependent upon one or more control signals (i). Its angular adjustment when extende...

The present invention relates in brief to an armrest holder 16 for pivotal attachment of an arm support to a chair, especially to a substantially vertical backrest part of such a chair. The armrest holder 16 comprises a tubular part 17, for rotatable reception of a part of the armrest, and a U-profile-shaped part 18, which is constructed in one piece with the tubular part 17 and is intended to at ...

Shock wave formation of thin layers of materials with improved superconducting and permanent magnetic properties and improved microstructures. The material fabrication system includes a sandwiched structure including a powder material placed between two solid members to enable explosive shock consolidation. The two solid members are precooled to about 80 DEG -100 DEG K. to reduce the residual tem...
