T...

The invention provides a heat-shrinkable thermoplastics packaging film comprising a laminate of two or more individual heat-shrinkable thermoplastics packaging films, where each of the individual films is substantially identical in composition and layer construction. The films are preferably prepared from double wound film, especially biaxially oriented film comprising LLDPE. The invention also pr...

Process and device for the production of reinforcing elements composed of resistant fibres distributed in three dimensions, according to which process, by means of a needle (3.1) driven in a to-and-fro movement, a continuous fibre (4) is introduced into a substrate (2), resting on a support (1) and consisting of such fibres crossed in at least two directions, by pricking from the free face (2a) of...

Cell lines have been produced that secrete human monoclonal antibodies capable of binding to molecules of different bacterial species. These antibodies have been found to be protective against lethal challenges of various bacterial genera. Pharmaceutical compositions containing these antibodies, which can be in combination with other monoclonal antibodies, blood plasma fractions and antimicrobial ...

Defibrillated paper is treated with water, lime, ground quartz and optionally a waterproofing agent and also optionally a flameproofing agent and then exposed to a heat treatment in an autoclave at above 200 DEG C, followed by final drying. This gives insulating boards which have good heat-insulation properties and good footfall sound insulation, can be adhesively bonded and have good adhesion pro...

A radially self-expanding implantable intraluminal device formed from a hollow tubular braid. The intraluminal device may be used in a variety of medical procedures which require a passageway to be maintained in an open position or which require reinforcement, support or a bypass conduit such as in blood vessels weakened by disease. The intraluminal device is longitudinally expanded or radially co...

In (I), q, r, s and t=0 or 1, provided that the sum of two or more adjacent q, r, s and t is at least 2; x=1-20; NA=a nucleic acid or a known nucleic acid deriv.; L=a covalent linker which is a direct bond or an organic gp. contg. at least one C, N, O or S atom; PA=a polyamide structure ...

PCT No. PCT/DK90/00077 Sec. 371 Date Sep. 20, 1991 Sec. 102(e) Date Sep. 20, 1991 PCT Filed Mar. 19, 1990 PCT Pub. No. WO90/11283 PCT Pub. Date Oct. 4, 1990.A process for the preparation of 9-substituted quanine derivatives of general formula (I), in which R is C1-C4-alkyl optionally substituted with one or more hydroxy groups, or R is ( alpha ), benzyl, ribosyl, 2'-deoxyribosyl or (CH2)n-OR1 wher...

In a computer where instructions are fetched in segments and where segments of an instruction are assembled before execution is initiated, processing of instructions is accelerated by examining segments of the instructions concurrently while they are being fetched. The information obtained from such examination is then used to shorten the decoding step for the instruction.

A closure for sealing the cutter guide tube of a pipe saddle fitting comprises a cap of thermoplastic material having a screw-threaded section (5) to enable releasable attachment of the closure to the tube, and a section (6) with a cylindrical surface incorporating a heating coil (8) to which a welding current is delivered to fix the closure permanently to the tube when the pipe joint has been com...

A container (100) capable of suspension in a toilet bowl and constructed so as to receive a water-soluble block (colour stick) is proposed, which container essentially comprises a shell body (10), a lid (50) articulated thereon and provided with a basket part (56) for the admission of water, and a correspondingly constructed closure member (30). The shell body (10) and the lid (50) are provided, o...

The present invention relates to a novel process for forming metal matrix composite bodies. Particularly, an infiltration enhancer and/or an infiltration enhancer precursor and/or an infiltrating atmosphere are in communication with a filler material (2) or a preform, at least at some point during the process, which permits molten matrix metal (3) to spontaneously infiltrate the filler material (2...

For the manufacturing of dry-formed webs of cellulose fibres there are two different ways of binding the fibres, viz. an application of glue to the web surfaces and, respectively, an admixing into the fibre charge of heat actuated binding fibres that are actuated by passing the web through a heating zone. The latter method is the better in practice, of course, in particular for liquid absorbing pr...
