Filed: 1989-11-10
Granted: 1991-12-31
Abstract: ABSTRACT OF THE DISCLOSURE   A hanger for holding a suspended ceiling made of a continuous wire.  The wire is shaped at one end, to form two superposed loops adapted to surround a screw which is intended to be threaded in a supporting ceiling. The wire is bent near the loops at about 90 degrees relative to the plane of the superposed loops.  The short end of the wire is either twisted to the body of the wire or located inside the apex of the angle formed by the loops and the body of the wire so that it will be tightened when the screw is threaded in the supporting ceiling and the body of the wire is under tension.

Abstract: COMPENSATED MICROWAVE FEED HORN                        ABSTRACT A feed horn employing a novel compensator design which substantially re-duces off-axis cross polarized components of circularly polarized energy over a wide range of angular directions. The compensator comprises a plurality of L-shaped compensating conductors disposed in a generally symmetrical fashion about a longi-tudinal axis of the feed horn. The conductors extend inwardly from the output aper-ture of the feed horn and then radially outwards a predetermined distance away from the axis toward the horn sidewall. The conductors are disposed at an angle relative to the axis, which angle is generally defined by an cone whose apex is the same as the apex of the feed horn. A nonconducting support structure supports the conduc-tors within the feed horn. A dielectric matching member is disposed in the feed horn to eliminate unwanted energy reflections.

Abstract: A co-variance microwave water cut monitor includes a test cell having a petroleum stream flowing through it while permitting the microwave energy to enter the test cell. A microwave source provides microwave energy to a circulator which in turn provides the microwave energy to an antenna. The antenna provides the petroleum stream=.in the test cell with the microwave energy and receives reflected microwave energy back from the stream. The reflected microwave.energy is provided by the antenna to the circulator which in turn provides the reflected microwave energy as test microwave energy. A detector assembly connected to the circulator detects the intensity of the test microwave energy and provides a corresponding intensity signal. Indicator apparatus connected to the circulator to the microwave source and to the detector assembly provides an indication of the water cut of the petroleum stream in accordance with the intensity signal and the phase difference between the source provided microwave energy and the test microwave energy.

IPC: H04B1/04
Filed: 1991-09-23
Granted: 2002-07-30
Abstract: A radio telephone uses a signal indicating the strength of received communication signals as a measure of prevailing signal propagation conditions to control the gain of a power amplifier in its transmitter. Where conditions are favorable, the gain can be reduced without deleterious effects on transmitted signals, and with a resulting savings in power drain on the radio telephone's power supply (e. g., batteries).      In this way, talktime on a single battery charge can be significantly lengthened. Where conditions are adverse, e.g., at outlying or fringe areas of a cellular telephone system of which the radio telephone is a station, the gain can be increased to produce stronger transmitted signals, at times extending the effective coverage area of such systems.      Preferably, the output of the power amplifier remains at all times within a power range prescribed by applicable standards, and is increased or decreased within the power range in accordance with prevailing conditions indicated by the received signal strength signal.
