Abstract: VENTED COMPRESSOR INLET GUIDE          Abstract of the Disclosure To provide reduction in temporary conditions of excess load on the thrust bearing, a labyrinth positioned contiguous to a leakage aperture in the high pressure side of a single stage overhung compressor rotor affords controlled leakage to a venting circuit in communication with a lower pressure system.  A pressure switch responsive to pressure levels in the venting circuit prevents compressor start at pressures above the set point of the switch while a backpressure valve in the venting circuit when operative maintains a predeter-mined pressure level therein.  When the thrust bearing is operating at speeds sufficient to enable acceptance of the load imposed by compressor pressure, an override solenoid valve serves to close the backpressure valve and operably shut the venting circuit.

Abstract: PRECISION CLEAVING OF OPTICAL FIBERS            Abstract Optical fibers are cleaved with high precision by a technique that yields flat endfaces that are perpendicular to the axis of the fiber within 1 degree, and typically within 0.5 degree.  This is very advantageous for obtaining low loss splices of fibers, especially single mode fibers.  In the present technique, a fiber is secured in two linearly aligned chucks in a sequence that allows one end to rotate unconstrained to minimize tortion.  An axial tension is then applied in the fiber" which is next scored.  The fiber then typically breaks, but cleaving can be promoted by applying further tension, or introducing moisture, if necessary.

Abstract: ABSTRACT      A status monitor for coaxial cable networks is disclosed.  The monitor is designed to be directly attached to an output port of an amplifier/repeater in the network and is used as an aid in trouble shooting faults in the network.  The monitor comprises a detector (12 or 40) which generates a d.c. voltage indicative of the level of a pilot frequency signal on the network.  This d.c. voltage is supplied to a plurality of voltage comparators (18, 20 and 22) which compare the d.c. voltage with different reference voltages in order to sense different fault conditions.  If a fault condition is sensed, the outputs of the comparators are used by a tone selection logic (24) and an OR logic switch (26) to control a voltage controlled oscillator (30) to generate a modulating tone.  A signal from a crystal controlled oscillator (32 or 46) or an IF output of the detector (40) is modulated by the tone produced by the voltage controlled oscillator and radiated.  This tone modulated radiated signal may then be used by a technician in the field to detect both the location and the nature of the sensed fault in the network.
