摘要： An air bearing supports and guides a moving web with a linearly constant distribution of air between the bearing and the moving web. An exterior tubular member is fixedly mounted over a first tubular member having a central bore connected to a pressurized air source. Air flow apertures are formed in the first tubular member in fluid flow communication with the central bore in the first tubular member. The exterior tubular member is formed of a porous, air permeable material to evenly distribute air flow from the air flow apertures in the first tubular member evenly about the periphery of the exterior tubular member to form a linearly constant, even distribution of air across the length of the exterior tubular member to evenly support a moving web.

摘要： A circuit for indicating angular position of a rotary member comprising a resolver including an amplitude stabilized sine-cosine generator coupled to quadrature windings of the resolver for providing a d.c. signal which varies as a linear function of the position of a rotatable member coupled to the resolver. The d.c. signal is fed to a plurality of comparators for comparing such angular position to a plurality of predetermined angular set points. The comparators are coupled to a priority encoder for indicating angular position of the rotary member. The encoder includes a switch array and a plurality of exclusive-OR gates for programming the encoder to provide a zero output at an arbitrary position of the rotary member. A digital voltmeter calibrated in angles of member rotation is coupled through a plurality of momentary contact push-button switches for normally receiving the d.c. signal indicative of angular rotation, and for alternatively and selectively receiving a signal indicative of a selected one of the set points for facilitating set point adjustment.

摘要： An apparatus for measuring the resistance and reactance of a subject, or a segment of a subject, includes a constant current source supplying a periodic high frequency input current to the subject. The constant current source controls the input current to a targeted value by measuring the actual current through the subject and comparing that actual current to the target current. The resulting error signal controls the input current. The input current is supplied to the segment through a coupling transformer, and another coupling transformer coupled to a resistor in the subject path supplies the value of the actual current. The apparatus also includes an impedance measuring circuit that detects an output voltage across the segment, preferably using a detection coupling transformer, and produces at least one of a reactance output signal and a resistance output signal using the output voltage. In one aspect, an automatic shut down circuit is included.
