  • Patent number: 6616797
    Abstract: Adhesive bonds can be formed by a process that includes applying a dispersion containing a polyurethane which has structural units of formula (I) —N═C═N—  (I) to a surface. The dispersion is first coated onto the surface to form a coating. The coating is dried to give an essentially anhydrous coating. The dried coating is then subjected to heat activation. The adhesive bond is formed by joining the heat activated coating to itself or to another surface.

  • Patent number: 5385967
    Abstract: An aqueous dispersion containing from 5 to 80% by weight of a copolymer A) having a glass transition temperature of from 50 to 150.degree. C. and from 95 to 20% by weight of a copolymer B) having a glass transition temperature of from -50.degree. to +50.degree. C., the glass transition temperatures of the two copolymers differing by at least 20.degree. C. at least one of the two copolymers containing from 3 to 70% by weight, based on the particular copolymer, of an ethylenically unsaturated C.sub.3 -C.sub.5 -mono- or dicarboxylic acid or of the anhydride thereof and the stated weights of the copolymers A) and B) being based on the sum of A) and B), is used as a sealable coating.

  • Patent number: 5281202
    Abstract: A device is disclosed for draining flexible fluid containers, in particular blood bags which form part of an extracorporeal system in a single needle-type arrangement, having a movable plate (4b) and a fixed plate (4a) in which both plates are configured to confront a flexible fluid container. A force member (14), and a force transfer means (8, 18), are arranged in such a way that the force acting upon the movable plate (4b) increases as the container is drained.

  • Patent number: 4688307
    Abstract: The invention concerns a receiver (1) in the probe head of a multiple-coordinate measuring machine in which probe-pin combinations (21) can be replaceably chucked with high precision with respect to their position in space. The receiver contains an isostatic three-point support (14) against which the base (15, 16, 17, 18, 19) of the probe-pin combination is drawn by an electrically operated clamping device. The clamping device is coupled with the control computer of the measuring machine so that a probe change can be effected automatically.In a preferred embodiment, the clamping device consists of a permanent magnet (11) and of an electromagnet (10) by which the field of the permanent magnet (11) can be selectively counteracted or increased to achieve pick-up and release functions. In another embodiment, a motor-driven screw thread performs the pick-up and release functions, and assures that the picked-up probe will unambiguously be drawn into correct isostatic engagement with the three-point support.
