Abstract:
An agent for determining ristocetin cofactor (v.Willebrand factor) is described, which contains platelets which have been treated with a tanning agent, with a protease inhibitor and, optionally, with a dye-stuff, and ristocetin A.
Abstract:
A process for the preparation of a factor VIII:C-deficient plasma is made available, in which a starting plasma is consecutively treated with antibodies against von Willebrand factor and antibodies against factor VIII:Ag. The deficient plasma prepared in this way contains less than 0.5% residual activity of factor VIII:C.
Abstract:
Process for the manufacture of a collagen solution and its use for the manufacture of collagen fibrillae for adsorbing coagulation factors, as diagnostic agent, for the manufacture of a collagen sponge and for use in a cosmetic preparation.
Abstract:
A method for the determination of soluble fibrin in a body fluid of a species is described, entailing use of a binding partner which is bound to a solid phase, and of a labeled bioaffinity binding partner, for fibrin.

Abstract:
A pattern, is imaged by means of a programmable mask, on a substrate that has a photosensitive layer, illumination spots being produced on the mask by means of an illumination unit and individual pixels being produced, via an optical unit, forming a grid of pixels on the substrate corresponding to the pattern. Structure edges that are to be reproduced on the substrate are positioned optimally. To this end at least two exposure processes for the photosensitive layer are performed, the illumination spots or exposure points of which are offset from one another. Thereby, spaces in the grid of pixels of the first exposure process, which spaces are proportionate to the number of exposure processes to be effected, are filled with pixels by the subsequent exposure processes.
Abstract:
What is disclosed is a plastics material adaptable to biomedical uses, the surface of which material at least partially consists of a graft copolymer having a hydrocarbon main chain and side chains grafted thereon, said side chains being polymers comprising at least one vinyl monomer selected from the group consisting of acrylic acid esters of the formulaCF.sub.3 --(CF.sub.2).sub.x --(CH.sub.2).sub.y --O--CO--CH.dbd.CH.sub.2,where x is an integer from 3 to 16 and y is an integer from 1 to 12, vinylene carbonate, N-vinyl alkylamides of the formula ##STR1## wherein R.sup.1 and R.sup.2 are the same or different and each is hydrogen or alkyl having 1 to 6 carbon atoms.
Abstract:
A coarse material comminution machine 1 comprises a rotor 2 fitted with blades 4 and a stator body 3 located on the stator side with at least one blade 5 adjustable by means of a control device 11 in the direction towards the rotor 2 and in the direction away from the rotor 2. The control device has an adjusting slide 12 that is movable relative to the rotor 2 as well as an activating device 13 for the movement of the adjusting slide 12 in the direction towards the rotor 2 and in the direction away from the rotor 2. The blade 5 is kinetically coupled to a movement of the adjusting slide 12. The blade 5 is connected to the adjusting slide 12 by one or several coupling members 14 connectible to the adjusting slide 11 and the blade 5 in form-fitting and detachable fashion.
Abstract:
The invention relates to an end wall module for a transport vehicle. The inventive end wall module having a first wall and the second wall arranged at a distance therefrom. The first wall is embodied in the form of a first corrugated structure and the second wall is embodied in the form of a second corrugated structure. Said corrugated structures are embodied in such a way that they are distanced from each other when the end wall module is mounted without being deformed and are engaged into each other by the shape thereof when the end wall module is at least in the first deformation stage.
Abstract:
The invention discloses an impact shears having a rotor with individual chopping blades disposed on the rotor in a predetermined arrangement and with blade(s) or blade system that is generally stationary vis-à-vis the rotation of the rotor. The blade is held in a blade holder on the stator side of the rotor. The blade holder is movable on the stator about an axis parallel to the rotational axis of the rotor and carries at least two blades, or blade systems, that are expediently disposed at the same angular distance to one another. The blade holder can be rotated about an axis that extends parallel to the rotational axis of the rotor so that every blade of the blade holder can be brought in a cutting position to interact with the chopping blades of the rotor and can be locked in position with respect to the chopping blades.
