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.

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:
The invention relates to the production of novel proteins exhibiting bonding activity for certain ligands, the so-called anticalins. To this end, the structure of peptides of the lipocalin family is modified by amino acid replacement in their natural ligand binding pocket using generic engineering methods. Alike immunoglobulin, the anticalin thus obtained can be used to identify or bond molecular structures.
摘要:
An initialization method for a wireless network is disclosed with at least one receiver node and/or switching node and transmitter node in which one transmitter node is allocated to at least one receiver node. An operating method is also disclosed for a wireless network with at least one receiver node and/or switching node and transmitter node. At least one allocation is made between a transmitter node and a receiver node after such an initialization method with the steps of: transmission of a wireless message at the transmitter node, reception of the wireless message at one or more switching nodes, and if the switching node is not the receiver node, transmission of the wireless message at the switching node and reception of the message at the preset receiver node.
摘要:
A termination for a superconductive cable (1) is provided, consisting of a pressure-tight metal inner container (2) in which there is a liquid refrigerant and into which the cable protrudes, and a metal outer container (3) which is separated from the inner container by an intermediate space (4) in which vacuum insulation is applied. A first rupture diaphragm (6) is applied in the wall of the inner container (2) and a second rupture diaphragm (7) is applied in the wall of the outer container (3) level with the first rupture diaphragm (6). An evacuated relief space (8), which contains superinsulation and is sealed from the intermediate space (4) with the vacuum insulation by a pressure-tight wall (9), is provided between the two rupture diaphragms (6, 7).
摘要:
A superconductor cable includes a superconductive cable core (1) and a cryostat (2) enclosing the same. The cable core (1) has a superconductive conductor (3), an insulation (4) surrounding the same and a shielding (5) surrounding the insulation (4). A layer (3b) of a dielectric or semiconducting material is applied to a central element (3a) formed from a normally conducting material as a strand or tube and a layer (3c) of at least one wire or strip of superconductive material is placed helically on top. The central element (3a) and the layer (3c) are connected to each other in an electrically conducting manner at the ends of the cable core (1).
摘要:
A superconducting electrical cable is specified, which is surrounded by a cryostat (3), which comprises two concentric metallic tubes (4, 5) which enclose thermal insulation between them and is used to carry a cooling medium. The cable has at least one superconductor (1), which is composed of superconducting material, as well as a normal electrical conductor (7), which is composed of normally conductive material and is electrically conductively connected to the superconductor. The normal conductor (7) is arranged outside of but resting on the cryostat (3).
