摘要： A data acquisition and display device for acquiring and displaying the time history of the variations in an analog value includes digital circuitry which employs a staircase voltage generator operated at a first frequency to quantize a range of analog voltages which correspond to the expected variations in the analog value. When the staircase voltage equals an analog voltage corresponding to the instantaneous value of the analog value, a memory device is conditioned to receive data corresponding to the staircase value. The memory acquires the data at a second frequency selected by the operator to acquire a fixed number of data inputs over a selected time period for which the time history is desired, and the circuitry automatically terminates data acquisition when the fixed number of data inputs is acquired. The data is read out at a third frequency selected by the operator.

摘要： A contour molded galvo-motor coil together with the forming apparatus and the specific method of manufacture. A low inertia coil is formed which also allows a smaller air gap in the magnetic circuit of the galvo-motor. The associated improvement in galvo-motor efficiency results from the inverse square relationship between flux density and length of air gap. The formed coil is shaped as a section of a thin walled circular cylinder and impregnated with a compound during winding which when cured provides a rigid unitized coil structure. The low mass resulting from the absence of the conventional coil form and the high rigidity afforded by the coil shape and impregnation compound eliminate torsional deformation during operation and provide a galvo-motor having high efficiency and accuracy.

摘要： The amount of charge stored in a charge storage system can be transferred with negligible loss from the storage system to a charge detector without regard to the size of any distributed capacitance present on the line transferring the charge. This is achieved by charging a detector capacitor and the capacitance of the transfer line, to a reference voltage, allowing the stored charge system and the transfer line capacitance to equalize at a voltage level below the reference voltage, and transferring charge from the detector capacitor to the line capacitance and the charge storage system to return the line and the charge storage system to the reference voltage of charge. The voltage remaining on the detector capacitor is then equal to the original state of charge in the storage system. A particular circuit for performing this method in conjunction with semiconductor memory arrays is also disclosed.

摘要： A taut band suspension instrument capable of withstanding severe impact without permanent damage to the taut band suspension. The suspension system is characterized by a taut band which extends between the movable element and frame of the instrument, and has its respective ends mounted to slide along smooth surfaces spaced from the points of connection of the band with both the movable element and the frame. The smooth surfaces along which the band can slide allow the axis of the band to shift when the instrument is subjected to severe impact, and as a result, stresses in the band are substantially lessened. In the preferred embodiment, the instrument is a meter and two taut bands, one extending from each end of a movable coil of the meter, are used.

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： An adjusting device having a knob and an adjusting shaft which are concentric and accessible from the exterior of an electrical measuring instrument. The knob positions a preset pointer at a selected value on the scale of the instrument and the adjusting shaft independently locates a control magnet for zero adjustment of the instrument. The control magnet is rotatably retained in a U-shaped front wall of a bracket which is opposite the end of the adjusting shaft. The knob and adjusting shaft are mounted in a face panel of the instrument to be rotated independently of one another.

摘要： An inexpensive wattage indicator is provided in the form of a meter designed to indicate the sum of the voltage drops across a shunt in series with a source and load and a portion of a resistance means connected across the load. The resistance value of the shunt and resistance means and the meter scale are so adjusted that the indication of the sum corresponds substantially to the product of current and voltage supplied to the load thereby providing an indication of the wattage.
