摘要： A watt-hour meter has in its base the circular core of a current transformer, wound with the secondary coil, this coil being connected to the current coil of the meter driving unit. The heavy load-carrying conductors extending through this core as its primary winding are carried by the base and are in the form of oppositely facing ''''U'''' bars. A special meter box and terminal block facilitates the connecting of this combination in the circuit being measured. Alternatively it may be mounted at a different position, not in the circuit, in which case closing the cover causes the display of words indicating that it is not in service. Shiftable connection links reverse voltage connections in case the supply and load conductors are interchanged from the more usual arrangement, and also facilitate testing. The service connectors are especially suited for very heavy service conductors. Calibration is of the total self-contained meter, i.e. with current transformer as a part thereof.

摘要： A meter scale of transluscent plastic material and having indicia and a mirror thereon to avoid inaccurate readings due to parallax. The mirror is of a predetermined configuration and takes the form of a very thin film of reflective material bonded to a surface of the meter scale. The meter scale is made by printing indicia on a surface and heat transferring the very thin film mirror to a surface of the scale.

摘要： A MOVING COIL MEASURING INSTRUMENT, WHICH COMPRISES AN AXLE HAVING A PROJECTING ARM. A MOVING COIL IS SECURED TO THE PROJECTING ARM. AN ANNULAR CORE IS SURROUNDED BY THE MOVING COIL, AND AT LEAST ONE SPIRAL SPRING AND THE MOVING COIL ARE ADJUSTABLE AGAINST THE FORCE OF THE SPIRAL SPRING. THE SPIRAL SPRING IS OPERATIVELY CONNECTED WITH THE ENDS OF THE MOVING COIL. AN INSULATING DISC IS DISPOSED ADJACENT THE SPIRAL SPRING, AND A LAYER OF SOFT ELASTIC MATERIAL AND DAMPENING AXIAL OSCILLATIONS OF THE SPIRAL SPRING IS APPLIED SELECTIVELY TO THE DISC OR TO ONE SIDE OF THE SPIRAL SPRING.

摘要： In an industrial-type electrical meter, a transparent molded plastic bezel has molded index grooves in the periphery thereof so that the meter can be mounted in an indexed bracket in one of several mounting positions without use of tools. One embodiment of the meter has an interchangeable dial. Another embodiment of the meter has a weatherproof seal. Still another embodiment can be easily installed in an explosionproof case.

摘要： A watt-hour meter for alternating current is adjusted for accuracy of measurement of light loads by shifting a unitary part, preferably a screw unit, which is the only part that moves for this adjustment. The phasing plate which heretofore has been movable for light load adjustment is now fixed in position, dispensing with the relatively complicated means for achieving accurate light load adjustment by its movement. The illustrated moving adjustment structure of screw unit consists solely of a screw of magnetic metal carrying conductive sleeve means fixed thereon. The most effective part of the sleeve is copper. The screw can be turned from the front of the meter with a screwdriver and the threads are engaged under resilient tension to avoid backlash. The screw carries leakage flux between the central pole and two side poles. The movement of the screw unit varies the light load compensation by increasing the effect of the unit as to one side and decreasing it as to the other side, thus changing the magnetic dissymmetry.
