Abstract: The present invention provides a method for fixing and/or stabilizing a sample, in which the sample is put into a permeable container, the permeable container having an opening, which is pressed into the sample, then a portion of the sample brought into the permeable container in this way is separated from the rest of the sample, and the container filled with the sample in this way is immersed in fixing and/or stabilizing agents and the sample is fixed and/or stabilized.

Abstract: The invention relates to a system for collecting a biological sample comprising a container having at least one open end, a closure fitting on or in said at least one open end, a holding element connected to said closure and a solid matrix on which said biological sample is deposited, and optionally at least one processing agent, wherein said solid matrix is at least partially transferable into a liquid or dissolved state by changing at least one physico-chemical property of the environment of said matrix without disintegration of the biomolecules comprised in said biological sample deposited on said matrix.

Abstract: A cooling mechanism for a steam turbine is provided, which has, in the area of the valve connection a cooling channel, into which cooling steam flows from the flow channel, the steam then being fed as cooling steam in the area of the thrust balance piston.

Abstract: The present invention provides a method for fixing and/or stabilizing a sample, in which the sample is put into a permeable container with a maximum overall height of 10 mm, preferably of 5 mm, and the container filled with the sample is immersed in fixing and/or stabilizing agents and the sample is fixed and/or stabilized.

Abstract: A method for welding half shells and thus a method for producing large volume components, such as an inner housing for a steam turbine is disclosed. Two half shells are connected to each other forming a tube-like cross section, and are welded by means of a girth weld to two further half shells that are connected to each other.

Abstract: A Write Broadcast system and method uses a base station to write sent data to all or some selected number (sub group) of tags in a base station field simultaneously. By unselecting the tags that have been successfully written to, and requesting a response from the remaining tags in the field (or sub group), the system determines, by receiving a response to the request, that there are tags in the field (sub group) that were unsuccessfully written to. Another Write Broadcast signal is sent to these tags. The system is useful for quickly (simultaneously) “stamping” information on the tag memory of a large number of tags in the field of the base station.

Abstract: A master entity is capable of broadcasting commands to slaves which move to another state when they satisfy a primitive condition specified in the command. By moving slaves among three sets, a desired subset of slaves can be isolated in one of the sets. This desired subset of slaves ten can be moved to one of the states that is unaffected by commands that cause the selection of other desirable subsets of slaves. In the incorporated U.S. Pat. Nos. 5,550,547 and 5,673,037, certain subgroups of radio frequency tags are selected for querying, communicating, and/or identifying by commands from a base station.
