  • Publication number: 20020056345
    Abstract: A method and an apparatus for laser microdissection of specimen regions (23) of interest of a specimen (4) are described. In a first step, an incomplete cut line (25) enclosing the specimen region (23) of interest is generated by means of a laser beam (7). At the incomplete point of the cut line (25), there remains a web (26) which joins the specimen region (23) of interest to the surrounding specimen (4). In a second step, the web (26) is severed with a single laser pulse directed onto it, thereby completing the cut line. The specimen region (23) of interest is in that context detached from the specimen (4) and falls by the action of gravity into a collection vessel (19).

  • Patent number: 6384992
    Abstract: The application describes a holder for attaching a component with outside dovetail carriages to a bearing surface. A pin-like bolt and, next to it, a ssion spring, which is bent away from the bolt under preloading, are attached in front of the bearing surface as interacting holder components. The cross sections, the lengths and the distance between the bolt and the compression spring are adapted to the inner profile of the dovetail carriage. To attach the component, the dovetail carriage is pressed manually by means of the bolt and the compression spring, until it comes into contact with the bearing surface, and is latched in place. The bolt and the compression spring are pressed into the inner sides of the dovetail carriage on both sides by the preloading of the bent compression spring. Advantageously, the compression spring is additionally preloaded toward the bearing surface.

  • Patent number: 5904736
    Abstract: In washing agents containing tensides and cellulase, the properties of the cellulase which are relevant to the application were to be improved. This was essentially achieved in that use was made of a cellulase mixture in which the first component, with a CMCase activity of 1 U per liter and a protein concentration of a most 3 mg per liter, gives an increase in remission of at least 5 units in the secondary washing test and the second component, with a CMCase activity of 20 U per liter gives an increase in absorption in the cellulose decomposition test of at least 0.075.

  • Patent number: 5453200
    Abstract: In a process for separating the exocellular proteins from the micro-organisms of a filtered fermentation liquor, the removal of solid is to be improved while retaining the useful substance. This is achieved by, in a first stage, removing substances preventing protein precipitation with the aid of a solid adsorption agent; concentrating the remaining solution to a protein content of about 30 to 40% by weight; and then precipitating and separating the protein, optionally with the addition of precipitants for protein to accelerate the precipitation, at pH values between 6 and 10.
