Abstract: In one aspect, an integrated circuit (IC) includes a magnetic field sensor to detect speed and direction of angular rotation of a rotating magnetic structure. The magnetic field sensor includes at least two magnetic field sensing elements configured to sense changes in a magnetic field caused by rotation of the magnetic structure. The IC also includes an output port configured to provide an output signal of the magnetic field sensor. The output signal indicates the angular direction and one of the speed or a fault.

Abstract: A measuring device including a Hall sensor arranged in a centrally and axially movable manner in a magnetic tube. Each half of the magnetic tube includes a north and south pole that are diametrically opposed, wherein the north pole on the first half of the tube is also diametrically opposed to the north pole on the second half of the tube, and the south pole formed on the first half of the tube is also diametrically opposed to the south pole on the second half of the tube.

Abstract: The invention relates to a measuring device comprising a hall sensor, particularly for measuring devices, which is characterized by the fact that the hall sensor is arranged in a centrally and axially movable manner in a magnet pipe. Each half of said magnet pipe is transverse-magnetized with opposite polarity.

Abstract: A bomblet has a casing and a targeting device provided with a reflector swingably secured to the casing. The reflector has a position of rest in which it is situated within a cross-sectional outline of the casing and a working position in which it is in a deployed state externally of the casing. A first guide arm is articulated to the reflector to provide for a relative pivotal motion about a first pivotal axis, and to the casing to provide for a relative pivotal motion about a second pivotal axis. A second guide arm is articulated to the reflector to provide for a relative pivotal motion about a third pivotal axis, and to the casing to provide for a relative pivotal motion about a fourth pivotal axis. All the pivotal axes are parallel to and spaced from one another and are perpendicular to the central longitudinal axis of the bomblet. The guide arms guide the reflector in a swinging motion from the position of rest into the working position.

Abstract: Escape of the blow medium at the blow mandrel/HDPE contact surface is prevented during extrusion blow molding of HDPE with an aggressive blow medium if a blow mandrel with a movable sealing element is used.

Abstract: A safety plug socket has two independently actuated circuit breakers. The two circuit breakers are in the form of a common C-shaped leaf spring and two conducting actuating pins which are movable to close the circuit breakers when a plug on a line cord from a consumer appliance is inserted into the socket of the circuit outlet to move the actuating pins of the two circuit breakers into contact with the conductive leaf spring. In one form of the invention, the biasing springs of the circuit breakers are current carrying and form a part of the supply circuit. In another form of the invention, each circuit element comprises leaf spring contact arms which are bridged by a conductive bridging member carried by respectively actuating pins of the circuit breakers. Power can only be obtained from the outlet socket when both circuit breakers are closed and when the plug from the consumer appliance has been moved into the outlet socket, which action closes off access to the tubular contacts to the circuit breakers.
