An arrangement for an electrically conducting connection of a superconductive electric cable with a cable having normal conductivity at room temperature is provided, which includes a passage with an electric conductor surrounded by a thermal insulation. The conductor of the superconductive cable is connected to an end of the conductor of the passage, at whose other end a cable having normal conductivity can be connected. On the end of the superconductive cable intended to connect to the conductor of the passage an electrode is mounted serving the electric field control. At least in the area of the electrode a cryostat is present which surrounds it, which is constructed as a circumferentially closed sheath of electrically insulating material with a vacuum free, thermal insulation. The end of the sheath facing the passage is placed during the state of operation of the arrangement at high voltage potential, while the other end is connected to ground potential.

A rock bolt well adapted for use in mining is provided. The rock bolt includes an anchor tube that encloses an interior space, a fixing agent arranged inside the interior space for the substance-to-substance fixation of the anchor tube to stone, a mobile piston arranged inside the interior space for transporting the fixing agent out of the anchor tube when the anchor tube is arranged in a bore hole in the stone, a piston moving mechanism, an anchor nut, and an anchor plate supported by the anchor nut for support on the stone.
摘要:
A device for the wire-free determination of a position of a mechanical force-transmitting device, having at least one storage device for storing electrical energy, at least one sensor element which detects the position and is monitored by at least one sensor electronic unit, including at least one radio transmitter, and at least one photovoltaic energy supply device supplying the storage device with electrical energy.
摘要:
A clamp for securing a tubular or hose-shaped object on a support. The clamp includes a clamp jacket having first and second ends, wherein a first leg protrudes from the first end of the clamp jacket and a second leg projects from the second end of the clamp jacket. The first leg has a lug which in the open state protrudes in the direction of the second leg. The second leg includes a fastening section which can be inserted into a gap between the lug and a neighboring portion of the first leg located opposite the lug, wherein, in the closed state of the clamp, the lug is plastically deformed toward the outer side of the fastening section facing away from the first leg.

A building equipment control system with at least one partial system comprising a sensor and/or an actuator, each of which is coupled to a processing unit and which incorporates a wireless signal transmission and reception unit that is coupled to the processing unit.
摘要:
A heating ventilating air condition system, comprising an adjustable air vent, configured to control the rate of air flow rate through the vent, an actuator, configured to control the adjustable air vent, and an ambient energy harvester, configured to supply energy to the actuator, wherein the energy required for operating the actuator is provided by the ambiance.
摘要:
A multi-speed sprocket assembly is suggested, including at least a larger sprocket and at least a smaller sprocket. The smaller sprocket has a trailing tooth which is last to engage the chain before moving onto the larger sprocket. The larger sprocket has a leading tooth which either is the first to engage between a first outer link plate pair of the chain or is located adjacent to a first inner link plate pair of the chain. At least the larger sprocket has an upshift transitional region which has a double spacewidth created by omitting a tooth and is immediately followed by the leading tooth. In the region of the double spacewidth, the larger sprocket is embodied in such a way that a crossing chain link comes into contact with the larger sprocket only in the region of the leading tooth.
摘要:
A sensor system has a least one voltage generator for conversion of non-electrical energy to electrical energy. At least one energy store is connected downstream from the voltage generator. At least one voltage converter is connected to the energy store such that its output signal is suitable for operation of a processor controller. At least one sensor is provided, and at least one transmitter enables wire-free transmission of transmission messages produced by the processor controller and containing at least one measured value from the at least one sensor. A timer circuit is triggered as a function of a voltage level of the at least one energy store, and activates the sensor system to transmit at least one transmission message after a specific time interval.
