摘要:
An adapter (1) and electrochemical gas sensor (2) is provided with an electrochemical gas sensor housing (14) accommodating an electrolyte (13), with at least one measuring electrode (12) arranged therein and with a membrane (11), which screens the measuring electrode (12) from a measured gas and is permeable to the measured gas. The measuring sensitivity of an electrochemical gas sensor is increased by the adapter (1) having a gas-impermeable surface (15) extending in parallel to and at a spaced location from the membrane (11). The adapter (1) and the membrane (11) form a flow gap (10) for the measured gas delivered by a pump. The adapter (1) may be plugged onto the electrochemical sensor (2) at its outer edge (1a). The measured gas enters through a central opening (17), expands in the flow gap (10) radially to the outside and leaves same via the ring-shaped gap (16).

A filling device for an anesthetic evaporator has filling of an anesthetic evaporator is possible. To accomplish the object, an additional vent hole (36), which is opened immediately after the filling in order for excess anesthetic volume to be able to flow out of the filling device into the anesthetic tank (15) of the anesthetic evaporator (2), is provided within the filling device above a fluid channel (14), via which both the gas and liquid exchange takes place during the filling.
摘要:
A method and assembly for securing a cylindrical centering pin in a bore formed in a plate includes introducing an end of a centering pin to be secured to a plate into a bore formed in the plate until at least part of a coaxial, radially deformable wall portion of the end to be secured protrudes beyond the plate; and generating pressure in a closed hollow space surrounded by the wall portion with a pressure fluid until the wall portion radially expands and anchors the centering pin. According to another method and assembly, the end is introduced into the bore until at least part of the end to be secured, which has a periphery and an interior with radial slits formed therein, protrudes beyond the plate; and a mandrel-like tool is partially brought into the slits in the interior of the end of the centering pin and radially expands the end of the centering pin with the tool for anchoring the centering pin.

A repair fixture for water-cooled nuclear reactors including an openable reactor pressure vessel having a wall, and conduits passing through the pressure vessel wall for flooding the pressure vessel, includes a sealing box disposed in the opened, flooded pressure vessel, a device connected to the sealing box for pressing the sealing box liquid-tightly against the pressure vessel wall enclosing at least some of the conduits, and a device connected to the sealing box for evacuating the conduits enclosed by the sealing box.
摘要:
A pressure-resistant tank for liquids includes a plurality of differently shaped diecast parts (1, 2) made of a first aluminum alloy (cast alloy). The diecast parts (1, 2) are connected by means of a closed weld seam welded with an electron beam with the use of a second aluminum alloy (wrought alloy). The second aluminum alloy has especially a hydrogen content of less than 0.2 mL per 100 g of wrought alloy. The tank for liquids is especially an anesthetic tank and the anesthetic is desflurane.
