Abstract: Abstract A method and apparatus for testing circuit boards using two or a small number of probes for making resistive and radio frequency impedance measurements e.g. capacitive measurements.  The combination of resistive and impedance measurements substantially reduces the number of tests required to verify the integrity of a circuit board.  The impedance or capacitive "norm" values used in testing the circuit boards can be obtained by operating the system in a learning mode.          Analysis of the data provides not only fault detection but also can indicate approximate fault location.

Abstract: ABSTRACT OF THE DISCLOSURE            This invention relates to the tracking of a pipeline pig during its movement through a pipeline carrying gas, for instance.            The pig is tracked by detecting energy emission resulting from impact of the moving pig with at least two previously identified features which are located within the pipeline at known spaced intervals.   The energy emission takes the form of vibrational signals which are sensed by a geophone(1)which is coupled externally to the wall or associated equipment of a gas pipeline (2). An electrical output proportional to the vibration is amplified by a preamplifier (5) and is then filtered by a unit(6)to remove unwanted frequency components of the signal.  The filtered signal is fed to a chart recorder (7).          The unfiltered preamplifled signal is fed to an audioamplifier(9) where the signal is amplified to audible levels.

Abstract: Abstract of the Disclosure The present invention is directed to a rotary shaft seal assembly (41) and, more particularly, to an assembly including a continuous, annular, but axially variable seal (52, 66) for providing hydrodynamic lubrication between the seal (52, 66) and the rotating shaft (14).   The seal assembly (41) uses differential pressures to maintain the seal (52, 66) compressed as it wears.  The present system is particularly useful in drilling motors utilizing the movement of drilling fluid under pressure to operate the motor parts and thereby to drive a drill bit.  Annular seal mounting members (59, 46) are positioned above and below the seal (52, 66) and have surfaces (64, 53) to matingly engage the seals (52, 66).  The mounting members (59, 46) are permitted to move relative to one another in response to a pressure differential developed across the motor to compress the seals (52, 66) therebetween to accommodate wear.          An oil chamber (28) above the upper mounting element (59) communicates drilling fluid pressure inside the drill pipe to the upper mounting element (59).  The pressure of the annular space below the motor housing is communicated to the lower mounting element (46) by means of a lower chamber (51).  The seals (52, 66) are protected from the abrasive drilling fluids by the fluids in the chamber (51) and seals (47).

Abstract: Abstract of the Disclosure Bar codes are shown for measurement of volumes of liquids, e.g., the amount of milk collected in a dairy milking operation, and correlation therewith to identification of the source of the liquid, such as a cow.  In the preferred embodiment, infrared or laser scanners are used to scan bar codes to provide an input to a computer for correlating the container or the source of liquid with the volume of liquid, whereby complex volume measuring devices and operator measurements can be substantially eliminated.  Similar techniques can be used to provide computer input data representing a wide variety of analog inputs; e.g., by providing a bar code scale for juxtaposition to a thermometer, the segments of the code along the scale being selected in accordance with the mercury level at a given temperature, simple analog-to-digital temperature data conversion and input is obtained.  Methods and apparatus for providing machine-readability for a number of differing types of analog instrumentation are described.

Abstract: ABSTRACT OF THE DISCLOSURE          A power transfer circuit includes a power transformer having a center tap provided in its secondary winding,  a full-wave  rectifier circuit,  a level discriminator circuit and a switching circuit.   In response to a level discrimination made by the level discriminator circuit that a DC voltage outputted from one output terminal of the full-wave rectifier circuit is less than a predetermined voltage level, a transistor and a thyristor of the switching circuit are made conductive so as to ground the other output terminal of the full-wave rectifier circuit.  In response to a level discrimination made by the level discriminator circuit that the DC voltage outputted from the said one output terminal of the full-wave rectifier circuit exceeds the predetermined voltage level, a diode connected to the center tap of the power transformer is made conductive to ground the center tap.  Thus, the full-wave rectifier circuit outputs a constant DC voltage even if AC voltages at different levels are inputted in the primary winding of the power transformer.
