Abstract: NE-103 (019A/4) "Paging Receiver Having a Noise-Immune Verification Circuit for Disabling Battery Saving Operation" ABSTRACT OF THE DISCLOSURE A selective calling radio paging receiver includes a battery saving controller which activates the high power drain unit of the receiver at periodic intervals for allowing the detection of a preamble contained in a received digital paging signal and deactivates it for a period longer than the period of activation for power savings purposes. The power saving is disabled in response to the detection of a preamble for continued power activation to permit a sync detector and an address detector to be operated in succession. A window pulse is generated in synchronism with the clock timing of the received digital signal so that its binary level transition is time coincident with each window pulse. If noise occurs in the received signal, binary level transitions occurs which are out of coincidence with window pulses. The time-coincident binary level transitions and the noncoincident binary level transitions are counted to give first and second counts, respectively. If a valid preamble is lost or corrupted and if the first count is greater than the second, a valid indication of the received signal will be given and power activation is continued to operate the sync and address detectors in succession.

Title: Methods of soot overcladding an optical preform
Inventor: NARASIMHAM PUNDI L
IPC: G02B6/00
Filed: 1987-08-27
Granted: 1994-03-08
Abstract: 17.          METHODS OF SOOT OVERCLADDING AN OPTICAL PREFORM          Abstract An optical preform is prepared first by depositing soot about a glass substrate rod to form a boule.  Then the soot boule is sintered to consolidate the material and provide a preform from which optical fiber is drawn.  The boule is relatively large so that the resulting preform is capable of providing more optical fiber than those used in the past.  In order to be able to sinter successfully the enlarged boule, microwave energy from a furnace is coupled to the glass rod so that the sintering proceeds from the rod radially outwardly thereby allowing gases readily to escape and rendering the process highly efficient.

Title: Liquid/gas bypass
Inventor: WENDSCHLAG JAMES C
IPC: F25B41/04

Granted: 1991-05-14
Abstract: Title LIQUID/GAS BYPASS                            Inventors James C. Wendschlag James W. Larson Abstract A liquid/gas bypass line bypasses an expansion device of a refrigeration apparatus.  An inlet of the bypass line is connected slightly above the bottom of a condenser so that it can pass either liquid refrigerant or vaporous refrigerant, depending on the level of liquid refrigerant in the condenser.  The other end of the bypass line is connected to discharge into the evaporator, bypassing the expansion device.  The bypass line functions as a conventional hot gas bypass during low load conditions when the level of liquid refrigerant is below the line's inlet.  When the level rises above the inlet, often occurring when the condenser coolant temperature is low and the compressor is fully loaded, the bypass line returns excess accumulated liquid refrigerant to the evaporator.  Maintaining the proper levels of liquid refrigerant in both the condenser and the evaporator not only provides the most effective use of their heat transfer surfaces, but also promotes the proper return of oil to the compressor.
