Date Oct. 16, 1997The invention relates to a process for checking a hollow body section, wherein the section, after being filled with a fluid, is subjected to a bursting test to demonstrate its brittle fracture resistance. After the open ends of the section are closed, the required bursting pressure is applied by the dynamic movement toward each other of two elements that reach in a sealing manner through the open ends. The dynamic movement of the two elements is achieved by accelerating a weight toward one of the two elements such that the weight impacts the one of the two elements at an impact velocity, causing the dynamic movement.

Abstract: In accordance with the present invention, there are provided compositions and methods useful for the  in vivo  delivery of substantially water-insoluble pharmacologically active agents (such as the anticancer drug paclitaxel) in which the pharmacologically active agent is delivered in the form of suspended particles coated with protein (which acts as a stabilizing agent).  In particular, protein and pharmacologically active agent in a biocompatible dispersing medium are subjected to high shear, in the absence of any conventional surfactants, and also in the absence of any polymeric core material for the particles. The use of specific composition and preparation conditions enables the reproducible production of unusually small nanoparticles of less than 200 nm diameter, which can be sterile-filtered.

Abstract: A rotating cutting tool having a tool body, in which cutting inserts are clamped without auxiliary equipment and without the aid of movable clamping elements. To this end, the tool body is provided with receiving grooves, which narrow toward the circumferential surface. Moreover, the grooves narrow in the transverse direction, i.e. approximately in the direction of the axis of rotation of the tool body. This is achieved, for example, by means of an inclined base surface. Correspondingly shaped cutting elements, such as wedges, are pressed into the grooves from the side, and are clamped over a large area by means of a wedge action. The result is a reliable, particularly simple and precise mount for even sensitive cutting elements.
