Abstract: Abstract of the Disclosure A transceiver transmit/receive (T/R) switching arrange-ment for electrically decoupling the transceiver's receiver circuit from first and second transceiver ports during trans-mission, and for electrically decoupling the transceiver's transmitter circuit from the first and second transceiver ports during reception.  Each such circuit includes an ampli-fier for amplifying an applied microwave signal and operating with a relatively high output impedance when power is applied thereto.  Each amplifier is inhibited from amplifying an applied microwave signal when power is removed therefrom.          First bias means switchably applies power to the transmitter amplifier during transmission and removes power from the transmitter amplifier during reception to switch the rela-tively high output impedance of such amplifier to a relatively low output impedance.  Second bias means switchably applies power to the receiver amplifier during reception and removes power from the receiver amplifier during transmission to switch the relatively high output impedance of such amplifier to a relatively low output impedance.  Additional circuitry in the transmitter circuit couples the amplified microwave signal from the transmitter amplifier to the second trans-ceiver port during transmission, and transforms the relatively low output impedance of the transmitter amplifier to a rela-tively high impedance at the second transceiver port during reception. Similar circuitry in the receiver circuit couples the amplified microwave signal from the receiver amplifier to the first transceiver port during reception, and transforms the relatively low output impedance of the receiver amplifier to a relatively high impedance at the first transceiver port during transmission.

Abstract: PHASE-LOCKED LOOP FOR MFM DATA RECORDING               ABSTRACT OF THE DISCLOSURE    A phase-locked loop (PLL) for use in decoding MFM data recordings.  The loop uses a counter to generate timing signals which divide bitcells into data and clock windows and which define times within these windows at which transitions in the MFM signal are expected to occur.  Data and clock windows of differing relative size are readily accomodated.  The PLL has two synchronization modes:  one mode allows the PLL to take maximum advantage of both data and clock transitions which occur when reading actual data; a second mode is used during the synchronization period at the beginning of a data block and allows the PLL to lock quickly yet assure that it will lock to the bit frequency and not lock to harmonics or beat frequencies.  A charge pump generates the PLL error signal by responding to pump-up and pump-down control signals which are set and cleared in response to the timing signals from the counter and in response to the detection of transitions in the input signal.  While in data mode, a second counter is used to control the charge pump when a transition occurs after the time the transition is expected to occur.  The charge storage circuit of the charge pump control over loop dynamics. The PLL includes a VCO with an automatic dynamic adjustment of the VCO's center frequency which is accomplished by adjusting the reverse bias voltage on a diode that functions as the timing capacitor for the VCO. This adjustment allows the PLL to make maximal use of the VCO's range.

Abstract: PROTECTIVE ENDOSCOPE SHEATH AND METHOD OF INSTALLING SAME   Abstract of the Disclosure An endoscope sheath having a flexible tube surround-ing the elongated core of an endoscope.  The flexible tube has a transparent window near its distal end positioned in front of the viewing window of the endoscope.  Channels for taking biop-sies, injecting air or injecting water to wash the window of the sheath may extend along the endoscope, either inside or outside the sheath.  Where the channels are positioned inside the sheath, they may be inserted in a longitudinal groove formed in the endoscope core.  The protective sheath may be used with either end-viewing endoscopes or side-viewing endo-scopes.  In the latter case, the channel for taking biopsies extends through an elongated elastomeric membrance so that a catheter through the biopsy channel may be moved longitudinally by manipulation of an elevator.  The protective sheath may be installed by rolling the elastomeric tube into an annular configuration and then unrolling the tube over the core of the endoscope.  Alternatively, the tube may be inflated in its unrolled configuration to expand the tube and allow it to be easily slipped onto the endoscope core.  A variety of special-ized endoscopes may be created by using protective sheaths having a variety of special purpose medical instruments mounted at the end of a biopsy channel and operated through the channel.

Abstract: ABSTRACT     The horizontal wrapping machine of the type werein a succession of articles are fed into a traveling tube of web material which is sealed longitudinally and severed and sealed between the articles to produce individual hermetically sealed packages.  A conventional D.C. motor drives a conveyor which may be provided with article feeding flights and a switch, actuated once each revolution of the motor shaft, provides a pulse corresponding to each flight on the article feeding conveyor.  In addition an encoder driven by the D.C. motor shaft provides a digital velocity signal used as a reference signal for servo motors that may be coupled, in combination or individually, to drive web feed rolls, longitudinal sealing wheels and one or more sealing and severing heads.  A delivery conveyor transporting individual packages may, through a suitable drive train, be driven by the D.C. motor.  The velocity of the servo motors is established and controlled through an industrial computer, at a percentage of the velocity of the D.C. motor.  Thus, the digital velocity signal input to the computer by the D.C. motor establishes a reference velocity for the velocity of the servo motors.
