According to the invention, the cooling water flowing in the dry cooling circuit (11) is separated from the cooling water flowing in the wet cooling circuit (14), and the dry and wet cooling circuits (11, 14) are connected to a common condenser.

Abstract: A grip arrangement, for a medical instrument having a handle with two rod-shaped grip parts each with a grip surface, has, for each grip, a grip shell which can be secured in a detachable manner on the respective grip part, with in each case a grip surface of the grip parts which is of a larger size and/or of a different shape compared to the grip surface of the grip parts.

Abstract: The invention relates to an air cooled condenser system that contains a steam-air heat exchanger (3) consisting of tubes (2) finned on the outside for the partial direct condensing of steam (1) with ambient air (4). This heat exchanger (3) receives the steam (1) from an upper distribution chamber (24) and ends in a lower chamber (25) which collects the condensate (8) and the steam (27) that has not yet condensed. The steam (22) not yet condensed in the steam-air heat exchanger (3) is condensed, in the steam-air section of the air cooled condenser, in a space operating as a direct contact condenser (9) by spraying water from the water-air cooling section (7) of the air cooled condenser, where the non-condensing gases are removed as well. The water (13) heated up in the direct contact condenser (9) is re-cooled in a water-air heat exchanger (7).

Abstract: The invention relates to a process for the analysis of molecules having a molecular weight of <1500 Da by matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS), wherein an analyte containing low molecular weight molecules is applied to a matrix material, which is characterized in that the matrix material comprises fullerene-derivatised silica. This process allows clear identification of small molecules through intensive signals without matrix -related background disturbances.

Abstract: An air-cooled condenser comprising a distributing chamber for distributing a vaporous medium to be condensed, a condensate collecting chamber and finned tubes with fins on air side, said finned tubes being connected in parallel between the distributing chamber and the condensate collecting chamber, where each of the finned tubes comprises two parallel essentially flat side walls and exterior closings connecting the side walls, in the finned tubes there are longitudinal separation walls connected to the side walls and dividing the inner space of the finned tubes into longitudinal parallel channels, and in the separation walls there are breakthroughs and closure elements for allowing the flow of the medium between neighboring channels.

Abstract: A mechanism and applier therefor which is capable of inverted anastomosis of two lumens by an absorbable fastener. The fastener is made from two washer-like plate assemblies and a pair of introducers. Each such plate assembly has slots to receive latching prongs protruding from the other plate, and pins to impale tissue. Fastening is done through an applier that causes the pins to pierce the tissue, and causes a knife blade to cut through excess tissue. Fastening is done by attaching fastener halves. Insertion and removal of the fastener and applier optimally is done in an endoscopic procedure through a trocar or through the surgical incision in an open procedure. The system can be used such that the plates can be placed to properly set gaps between and anastomose tissue. The introducer portion will soften intraluminally and be expelled, in about 24 hours. The coupler portion will remain in place for 2-3 weeks, typically, and then fragment and be expelled with the feces.

Abstract: A heat exchanger in a close cycle gas turbine power plant has, on its heat abduction side, a system of cooling units connected to it by means of which the efficiency of the plant is considerably increased. Such units consist of evaporators and vapor turbines with condensers and air coolers, the vapor turbines being driven by vapors generated in the evaporators. The latter, in turn, are heated by the heat abduction side of the heat exchanger in the main cycle. The exhaust vapors are precipitated in condensers and cooled down by air coolers and recoolers and partly circulated back to the heat abduction side of the heat exchanger in the main cycle.
