    Abstract: An electrical test lead includes an insulated electrical cable having a proximal end and a distal end, an electrical connector disposed at the proximal end of the cable and connected to a test instrument, and an electrically conductive magnetic probe disposed at the distal end. The probe is adapted to magnetically attach to a test point in an electrical system and to provide an electrical connection from the test point through the probe, the cable and the connector to the test instrument. Together, the test lead and the test instrument may be used as an electrical test kit. The test lead may further include an additional electrical test lead component magnetically attached, and electrically connected, to the electrically conductive magnetic probe and extending therefrom. An additional electrically conductive magnetic probe or a non-magnetic electrical connector may be disposed at the distal end of the additional electrical test lead component.

    Abstract: An instrumentation apparatus with curable internal magnets is shown. The apparatus comprises a magnetic rotor and a rotatably mountable spindle to which the magnetic rotor is attached. A support structure to which the spindle is rotatably mounted defines at least one retaining area. A material is poured into and cured in the retaining area, and then charged to form a magnet. The molded and cured magnet provides a constant magnetic field that acts upon the magnetic rotor, providing a return-to-zero function or a volt gauge function for the instrumentation apparatus.

    Abstract: The coils for a meter current magnet are each formed from a strip of copper, with insulative coating, wound upon itself. A lead-in from its inner end is formed by the strip itself which is extended out around the coil. Flat bends (within the plane of the portion of bent strip) are made possible by forming the blank for the coil with parallel slots in the area to be thus bent. A tie for the outer layer comprises a tongue on the next layer extending through a slot in the outer layer, insulated from it by a plastic sleeve. The wound coils are insulatively coated and insulated from the magnet core and protected from its edges by molded nylon isolators of split-sleeve nature which, in final positioning, are interlocked with the coils for mutual positioning. The coil is outstandingly economical of copper without overheating.

    Abstract: A device for providing a displacement representative of the magnitude of a signal. The device typically includes a rotor having a plurality of sections of high permeability material separated by areas of high reluctance. A magnetic flux is applied to a section of the rotor to produce an elastic restraint torque varying with angle, while another high permeability section responds to variations in the magnetic flux caused by the signal to produce a torque representative of the signal magnitude. This latter torque moves the rotor to the point where the restraint torque increases sufficiently to balance the signal torque. The resultant angle of rotation represents signal magnitude. The device may also be operated to provide a signal output representative of an input torque or force.

    Abstract: An electric meter particularly characterized by a small number of moving parts and simplified assembly. A coil assembly initially including integral support elements which permit connection of pivot bearings or taut bands is adapted to be accurately positioned for rotation on the supporting base by inserting the assembly into the base. Cooperating locating surfaces on the base and coil assembly provide for accurate positioning of the support elements so the axis of rotation of the coil is in a predetermined position relative to a magnetic circuit of the meter. After insertion of the coil assembly, the bridging elements are severed. A coil support form of unique construction includes motion limiting elements which cooperate with surfaces of the magnetic circuit to limit the permissible extent of movement of the coil, in the event of shock or impact, to positions well within the elastic limit of the supports which mount the coil for rotation. The coil support halves connected together in electrically insulated relation to each other. Damping rings can be secured directly to the respective coil support halves, after the coil form is assembled.
