摘要： A tree harvester, arranged on the movable arm of a forestry vehicle, and comprising a cutting tool having pivotable claws (1, 1', 2) with releasable locking means (11, 12) for relative, mechanical locking of the claws in an inwardly pivoted position, and a longitudinally adjustable arm (7), interconnected between the gripping claws (1, 1', 2) of the cutting means for simultaneous pivoting of the claws outwardly and inwardly, resp., said arm being adapted to admit, on desire, the first claw (2) independently to be pivoted relative to the second claw (1, 1'), wherein the outside of the first claw (2) includes teeth (12) adapted for engagement with a stud (11), arranged in the point end of the second claw (1, 1'), the geometry of the claws and the length of the interconnected arm are chosen such that the point end of the first claw moves inwardly of the point end of the second claw in the simultaneous pivoting motion.

摘要： A ferrofluid sensor assembly includes a permanent magnet which is supported in a hermetically-sealed housing by ferrofluid rings at each end of the magnet. However, the housing is large enough that the ferrofluid rings do not seal the end of the magnet against the walls of the housing. The housing is filled with a non-magnetic liquid that is immiscible with the ferrofluid. The nonmagnetic liquid wets the walls of the housing such that the ferrofluid rides on the thin film of the nonmagnetic liquid. The non-magnetic fluid is selected to have low viscosity, so that the magnet has a fast response time.

摘要： An inclination sensor includes: a case having a turning shaft section projected in a lateral direction on a front surface thereof; magnetism detecting means fixed on an upper side of the turning shaft section; a pair of magnets fixed in parallel to a rear surface of the case to be located on both sides of the magnetism detecting means; a pendulum axially supported by the turning shaft section to turn freely; and a pair of ferromagnetic bodies fixed on an inward surface of the pendulum. When the case inclines, one of the ferromagnetic bodies approaches the magnetism detecting means, and a magnetic circuit is closed by the pair of magnets and one of the ferromagnetic bodies. Magnetic fluxes of the magnets pass over front and rear surfaces of the magnetism detecting means.

摘要： Es wird ein Neigungssensor vorgeschlagen, der ein, in seiner Drehlage, relativ zu einem Neigungsbewegungen ausführenden Gehäuse, veränderliches Drehpendel (3) aufweist, das ein Magnetfeld erzeugt. Es ist vorzugsweise mindestens ein anisotropisches magnetoresistives Element (15,16) als gehäusefester Sensor (12) vorhanden, mit dem eine Änderung des Magnetfeldes detektierbar ist. Das Drehpendel (3) verharrt in Lotrichtung (9) aufgrund einer geringen Gewichtsunsymmetrie in seiner Ruhestellung. Die mit dem Drehpendel (3) erzeugbaren magnetischen Feldlinien (B) ändern ihre Richtung relativ zum Sensor (12) analog zu einer Änderung des Drehwinkels (α) des Drehpendels (3) aufgrund einer, beispielsweise durch ein Kraftfahrzeug hervorgerufenen, Neigungsbewegung.

摘要： An angle sensor comprising a housing (1) having horizontal and vertical axes, which housing is adapted to receive a magnetic core (5) such that the core remains in substantially the same plane, e.g. by floating on a liquid (4). The core is provided with two orthogonal windings (8,18). In use, an electric field is applied across the vertical axis of the housing, which electric field induces a voltage in the windings, wherein the magnitude of the induced field is dependent on the angle of the magnetic core to the horizontal winding.
