Abstract: An apparatus for detecting a faulty concentric neutral wire in a live power distribution cable may include, in one embodiment, a housing for sliding along a surface of a power distribution cable, a magnetic sensor, and a motion device. The magnetic sensor may be coupled to the housing and configured to detect a magnetic field produced by each concentric neutral wire as the housing moves along the surface of the cable. The motion device may also be coupled to the housing, and may detect motion of the housing relative to the cable. In some embodiments, a communication device may communicate data describing the magnetic field and motion to a destination device.

Abstract: A device for variable activation of valves for internal combustion engines, which is arranged in a cylinder head having a camshaft mounted in a fixed location with valves that close by means of spring force through a stroke transfer arrangement. This device includes a movable element mounted with a fixed pivot, and has a support cam and a control cam. An intermediate member is displaceably mounted and supported on the element, and is in engagement with a cam lever of the camshaft, as well as the stroke transfer arrangement. The intermediate member supports itself on the support cam and control cam with a non-positive lock, sliding during the stroke movement. Whereby the control cam determines the stroke movement to be transferred to the stroke transfer arrangement by the intermediate member, as a function of the pivot position of the element that can change its position.

Abstract: A device for variable activation of valves for internal combustion engines, which is arranged in a cylinder head having a camshaft mounted in a fixed location. The device has valves that close by means of spring force, and which are guided in a fixed location in the cylinder head together with a stroke transfer arrangement assigned to one of each of the valves. This device includes a movable element that is changeable in its position for setting the valve stroke setting. This movable element is arranged in the cylinder head, in a fixed location, as well as mounted so as to pivot about a pivot axis having a fixed position in the cylinder head, and has a support cam and a control cam. There is also an intermediate member that is supported on the element that can change position, and wherein this intermediate member is displaceably mounted, and is in engagement with a cam lever of the camshaft, as well as the stroke transfer arrangement.

Abstract: The production of compact molded bodies of rare-earth transition-metal boron carbide and boron nitride compounds configured so as to avoid a selective evaporation of individual components in the production process and enable an exact adjustment of the desired stoichiometry. The process is characterized in thata) a powder mixture with particles sizes from 1 to 250 .mu.

Abstract: The straightness of rolled steel is improved by controlled cooling with water under pressure which, depending on the composition of the steel, accelerates or retards the .gamma./.alpha.-conversion and prevents the rolling stock, while on the cooling bed, from being warped or increased in length by the conversion.

Abstract: Phosphoramidates and salts and salt complexes useful as anthelmintics are disclosed. The products are prepared by treating an aminobenzene with an appropriately substituted isothiocyanatoate.
