Abstract: A seat valve with electromagnetic actuation having switching noises during closure of the seat valve should be noticeably reduced independently of a temperature of a fluid in the seat valve, without considerably increasing the production costs of the seat valve. A sealing body of the seat valve is produced from a plastic which is selected from the group (PEEK, PEI, PASU and LCP), and the flow of force for fastening and for transmitting structure-borne sound from a sealing seat to a fastening surface has at least one transition from a metallic component to a component composed of plastic and a transition from the component composed of plastic to a fastening surface of some other metallic component. The seat valve may be used in hydraulic brake systems of vehicles, but also in gear mechanisms or hydraulic systems.

Abstract: A layer that is present on the inner side of barrique barrels, produced by wood toasting, is responsible for sensory enhancement of the wine stored therein. The extraction of these substances, so-called tannins, is greatest in a new barrique barrel and decreases as the barrel is used for a second and third time, thus increasing the storage time. It is not common to use the barrel more than three times. This results in considerable costs and material expenditure for the barrique barrels. In view of this, the aim of the present invention is to provide a barrique barrel that can be reconditioned. For this purpose, barrel staves are joined to form layered rings, which are assembled in layers to form a barrel instead of arranging the staves vertically as in conventional barrels. As the result of a detachable connection between the staves and the layered rings, the barrel can be disassembled and ground on the inside so that the barrel staves can be toasted again and assembled to form a new barrel.

A switch assembly is coupled to the housing and is operable to selectively deliver power to the first control channel and the second control channel.

Abstract: A seat valve with electromagnetic actuation combines, in one device, the functions of a seat valve, of a pressure-limiting valve and optionally also of one or more check valves. Furthermore, the switching noise of the seat valve function is reduced. In a de-energized state of an electromagnet, a fluid flow from a port P to a port TNC occurs only if a pressure difference between the ports P and TNC exceeds a limit value of ?pG, wherein the force of the specified pressure difference overcomes the force of a spring and therefore pushes a first sealing body out of a first sealing seat, and in the energized state of the electromagnet, a fluid flow from port P to port TNC occurs even in the case of a pressure difference less than ?pG if the force of the electromagnet together with the force of the pressure difference between the ports P and TNC overcomes the force of the spring, wherein the sum of the specified forces pushes the first sealing body out of the first sealing seat.

Abstract: A switch-extender is connected to a measurement system and to several DUTs. It splits a signal from the measurement system into several signals so that the several DUTs receive the same signal and can therefore be tested in parallel. The switch-extender further includes at least one amplifier and/or at least one attenuator for every output port so that every signal has the same signal level no matter what the individual attenuation factor of the signal connectors or of the internal printed circuit board is. Furthermore a method for calibrating the measurement system as well as for the switch-extender and the signal connectors describes how to obtain the needed calibration values both for the downlink path and for the uplink path without changing the signal connector.
