  • Determination of direct thrombin inhibitors in fluids like serum or urine
    Patent number: 9944971
    Abstract: The present invention relates to a method for detecting at least one direct thrombin inhibitor in a sample other than citrate plasma, comprising the step of mixing a sample containing a thrombin inhibitor with a composition containing thrombin under conditions which allow the thrombin to release a detectable substance from a chromogenic substrate.
    Type: Grant
    Filed: June 15, 2012
    Date of Patent: April 17, 2018
    Assignee: DOASENSE GmbH
    Inventors: Job Harenberg, Roland Kramer

  • Canned motor pump
    Patent number: 4890988
    Abstract: A canned motor pump wherein the can has two coaxial tubular walls defining an annular space for the flow of a heat exchange fluid which heats or cools the can. If the can has an end wall, the latter can be formed with an additional space which communicates with the annular space. The driven rotor within the can can be rotated by a stator which surrounds the can or by a hollow rotor which rotates the driven rotor by way of one or more magnets. The can can be heated by an electric heater.

  • Canned motor pump
    Patent number: 4838763
    Abstract: A canned motor pump wherein the can has at least two coaxial tubular walls defining an annular space for the flow of a preferably gaseous fluid which is used to facilitate detection of leaks in the walls of the can. Each tubular wall can individually seal the driving unit from the driven unit of the pump motor. The leak detector can generate visible, audible and/or otherwise detectable signals, and such signals can also serve to stop the motor in the event of leakage.
