摘要： Contact piece for an electric vacuum switch, including a contact carrier base, an obliquely slotted contact carrier wall having an upper surface and being integral with the base forming a pot-shaped contact carrier together with the bsae, the pot-shaped contact carrier being substantially formed of copper and having a circular cross-section, an unslotted substantially planar contact ring being formed of a contact material and being disposed in the upper surface of the wall, the wall having a circular groove with a rectangular cross-section formed therein extended downwardly from the upper surface thereof, and another unslotted ring formed of a material having a greater resistance than copper being disposed in the groove.

摘要： A device for preventing uncontrolled acceleration of an elevator car installed in an elevator installation. The device has a limiting cable guided over rollers in a direction of movement of the elevator car. A braking device which is joined to the elevator car is connected to the limiting cable by a release and brakes the elevator car in both a downward and upward direction when the limiting cable transmits a predetermined release force to the release. A speed limiter is connected to one of the rollers and stops the roller when the traveling speed of the elevator car exceeds a predetermined limiting speed either in a downward or upward direction. The release of the braking device is connected by a slide connection to the limiting cable for limiting the force transmitted to the release so that the limiting cable slides through on the side connection when a force is significantly larger than the release force required for releasing the braking device is transmitted from the limiting cable to the release of the braking device.

摘要： For the reduction of the work function of the electrodes, gas discharge arresters contain an activator which contains, for example, an alkali metal or nickel. Getter materials, for example barium aluminum, serve the purpose of gettering of gases which can arise in the surge voltage arrester during manufacture or during operation. With these substances, the spreads of the minium operating voltage can be maintained small as long as the activator is only moderately heated. For high loads, the activator contains an alkali metal or nickel and, in addition, barium aluminum, whereby tungsten and/or molybdenum is present as the additional substance. An activator of this type guarantees constant values of the minumum operating voltage and a narrow spread of these values even after a high electrical and thermal load. A frequent switching of the maximally permissible current is possible without an interfering alteration of the electrical characteristics.
