摘要:
In a conductor foil for conductively connecting electrical and/or electronic components, the conductor foil including printed circuit traces, insulated to the outside and applied on a non-conductive, elastically malleable carrier foil. The conductive foil also includes soldering surfaces connected to the printed circuit traces, for soldering to electric terminals of components, in addition, the conductor foil includes feed line segments through which the printed circuit traces are led to the soldering surfaces, in order, in response to shaking stresses, to avoid damage to the soldering points by vibrations transmitted by the feed line segments. Furthermore, the conductor foil has stiffening segments branching off from the feed line segments, the stiffening segments, in response to shaking stresses, causing a force diversion of the vibrations onto the stiffening segments via the feed line segment movable end, which is not connected to the soldering surfaces.
摘要:
A hose has an internal longitudinal channel in its sidewall as a safety device, to provide a prompt indication of impending failure or leakage into or out of the hose. A hose pump featuring such a hose is an improvement over conventional peristaltic pumps. A squeezing member constricts the hose to move a conveyed product along the hose, thereby causing wear on the hose. Such wear usually manifests itself first as a leak through an inner liner of the hose into the channel. The entrance of conveyed product into the channel, which can be detected by a change in pressure or electrical conductivity, is used as an indicator for wearing out of the hose. The use of such a hose minimizes release of hazardous conveyed materials from the hose into the environment or contamination of conveyed sensitive materials such as foodstuffs by the surrounding environment.

摘要:
A travel sensor (10) is proposed which has a insertion body (11) consisting of non-ferromagnetic material with good conductive properties. The insertion body (11) is submerged into a measuring coil (15) through which alternating current flows. In addition, the travel sensor is enveloped by a shielding sleeve (16) consisting of ferromagnetic material. Due to the alternating effect between the magnetic field of the coil (15), through which an alternating current flows, and the two materials, at designated frequencies of the alternating current and the respective volume of the insertion body (11) or the shielding sleeve (16), it is possible to compensate the effects of the temperature in such a way that at varying temperatures the measuring curves of the travel sensor (10) extend nearly parallel across the entire measuring range.

摘要:
A work cylinder in which the position of a work piston, its distance traveled at a given time and the speed at which it covers this distance are measured by a hollow-cylindrical sensor, and the results are delivered to an electronic switch device. The sensor serves as a passage for the breathing air of a breathing chamber of the work cylinder, as a result of which the sensor can be cooled. The work cylinder is intended for use to control vehicle engine clutches.
