    摘要: An electromagnetic device in which a coil is mounted in a magnetic field for movement in proportion to the electrical current flowing in the coil. The magnetic air gap is divided into two sections with separated centers and the coil is supported for swinging movement in both arcuate sections of the magnetic field. The linkages supporting the coil are selected so that a pointer attached to the coil moves along a straight line at a predetermined distance from the coil. The coil is continuous between the two sections of the magnetic field and the resultant force due to current in the coil causes the coil to swing the pointer along a straight path a distance proportional to the current in the coil.

    摘要: An unbalanced coil assembly for use in moving-coil instruments comprises a frame which carries the coil, two coaxial staffs, a pointer and platelike balance weight. When the coil assembly is mounted for turning movement about the common axis of its staffs and when such axis is located in a horizontal plane, the balance weight is caused by gravity to move to a level below the staffs. This balance weight extends beyond the outline of the frame so that some of its material can be removed by one or more milling or like tools until the coil assembly is properly balanced.

    摘要: A magnet-positioning device by which a cylindrical core magnet is accurately centered and securely held within an electrical instrument casing. The device includes a hollow bracket having inwardly projecting tabs on the sides thereof which provide a seat for the core magnet. An end of the magnet supports a circular plate which has a pair of notches at opposite points in the edge thereof. These notches are engaged by a pair of aligned centering screws which penetrate the bracket sides at an elevation removed from the inwardly projecting tabs. The screws cam the core magnet against the seat tabs and axially align the core magnet within the bracket and thus within the instrument casing.

    摘要: To produce an insulated current sensor for slaving power devices in the field of avionics, use is made of a magnetic core through which there passes an element traversed by a current to be measured. The magnetic core comprises a secondary winding across the terminals of which are connected an oscillator and a measurement device. The cooperation of the oscillator and of the measurement device makes it possible to circumvent all the traditional drifting of current sensors.
