Abstract: ABSTRACT OF THE DISCLOSURE A system for the wireless transmission of multiple information signals utilizing digital time division circuits between a base station and a plurality of subscriber stations. The subscriber stations may be fixed or movable. The number of time division circuits is determined by the transmission quality of the signals. The base station is inter-connected with an external information network, which may be analog and/or digital. The information signals are selected from the group consisting of voice, data, facsimile, video, computer and instru-mentation signals. The modulation level of the signals and the power applied to the system are adjusted in accordance with signal error detection in the system. The system is provided with spatial diversity by using a plurality of antennas selectively spaced from each other to provide relatively high signal reception despite signal fading. The base station operates over a plurality of RF channel pairs. Each channel pair operation is implemented by the combination of a transmit channel circuit for processing a given plural number of information signals received simultaneously over telephone company trunk lines for simultaneous transmission to different subscriber stations over a given RF channel, and a receive channel circuit for processing a plurality of signals received simultaneously over a given RF channel from different subscriber stations to provide information signals for trans-mission over the trunk lines.

Abstract: ABSTRACT A fiber optic doppler anemometer comprises a source of coherent light, a directional coupler formed by the combination of a pair of single-mode optical fibers, and a photoelectric transducer.  The first end of the first fiber receives an incident beam of light from the source and guides it through the directional coupler to the second end of the first fiber, which is located adjacent to a body of moving particles to be measured, where both the second end of the first fiber and the moving particles reflect a portion of the incident light back into the first fiber.  The reflected light, which has a frequency different from that of the incident beam entering the first fiber, is directed back through the directional coupler which couples a portion of the reflected light  toward the first end of the second fiber.  The photoelectric transducer receives the light emerging at the first end of the second fiber and converts it into analogous electrical signals.     This system may be used as a velocimeter using the Doppler effect to measure the velocity of moving particles and to measure the sizes of particles with Brownian motion.

Abstract: ABSTRACT OF THE DISCLOSURE     A urethral sphincter cuff is adapted to be surgically implanted so as to encircle the urethra.  When the sphincter cuff is filled, the urethra is squeezed, and the patient is continent.  When the cuff is deflated pressure is released from the urethra and urine may flow therethrough.  The sphincter cuff is provided with a tongue and buckle to allow adjustment during surgical implantation.  The tongue, on one side of the cuff, contains apertures which are adapted to fit onto studs on the buckle part.  After placement and adjustment of the cuff an adhesive can be applied to secure the tongue to the buckle.          The cuff also contains an occluding diaphragm which, when filled, squeezes the urethra to inhibit fluid flow, and when unfilled remains in a second position in which no tension is applied to the urethra.  Even when the diaphragm area is reduced to its minimum value (no pressure on the urethra) the diaphragm remains under tension so that its smooth surface does not wrinkle.  Providing a smooth diaphragm surface pushed against the urethra reduces the possibility of local necrosis of the urethral tissue.

Abstract: Abstract Olefin Oxidation Catalyst System The addition of redox-active metal components and ligands, alternatively or simultaneously, results in increased conversion and selectivity in the palladium-catalyzed oxidation of olefins to carbonyl products in the presence of polyoxoanions.  In preferred modes, heteropolyoxoanions and isopolyoxoanions containing tungsten, molybdenum and vanadium, individually or in combination, are described.  The use of copper as the redox-active metal component shows reduced allylic reactivity.  The elimination of chloride from the catalyst system provides substantial engineering advantages over the prior art, particularly, the reduction of corrosion and chloro-organic by-product formation.  The use of redox-active metal components and/or ligands makes the palladium-polyoxoanion catalyst system industrially practicable.

Abstract: ABSTRACT OF THE DISCLOSURE          A banking machine having a single opening for both envelope and individual check or note deposit is disclosed.  The entrance to the depository has a deposit item thickness sensor just inside of the deposit gate opening which can detect the difference between a thicker envelope deposit item and a thinner single sheet of paper. A computer is responsive to signals from the thickness sensor to control a deflector which permits envelopes to pass directly through to a sequential stacking deposit bin. Alternately, the thickness sensor causes the computer to control the deflector to divert a single sheet of paper into a read leg of the bifurcated transport.  After entering the read path, document alignment rolls placed at a slight angle to the direction of document travel tend to move the document toward a registration edge before the document passes the read head.  After passing the read head, the document returns to the common transport at a point just past the thickness sensor and traveling in the same direction as it traveled when first inserted.  This permits the document to be recirculated in the event that the document was not adequately aligned for good reading.  As the document is recirculated, additional aligning is provided by the alignment rolls until the document has been moved all the way against the registration edge and proper reading can be accomplished.

Abstract: POLARIZATION INDEPENDENT COHERENT OPTICAL           HETERODYNE RECEIVERS       Abstract The present invention relates to coherent optical heterodyning receivers which mix a received optical signal, including an arbitrary polarization state, and a local oscillator signal, including a fixed polarization state, while providing a performance which is independent of the polarization direction of a received signal. In one receiver version, the received signal is heterodyned using only aportion of the local oscillator signal, while in a second receiver version, the entire local oscillator signal is used. The combined polarized signals are split in a polarizing beam splitter between the two orthogonal polarization axes for propagation in separate branches. Each branch includes a photodetector and means for processing the resulting photodetector output signal to retrieve the modulation information from the processed signal. The sum of the two demodulated signals from the two branches provides a baseband signal independent of the polarization state of the received optical signal.

Abstract: ABSTRACT OF THE DISCLOSURE           A reflux condensing start-up system comprises a steam generator, a start-up vessel connected parallel to the steam generator, a main steam line connecting steam outlets of the steam generator and start-up vessel to a steam turbine, a condenser connected to an outlet of the turbine and a feedwater return line connected between the condenser and inlets of the steam generator and start-up vessel.  The start-up vessel has one or more heaters at the bottom thereof for heating feedwater which is supplied over a start-up line to the start-up vessel.  Steam is thus generated to pressurize the steam generator before the steam generator is supplied with a heat transfer medium, for example liquid sodium, in the case of a liquid metal fast breeder reactor.  The start-up vessel includes upper and lower bulbs with a smaller diameter mid-section to act as water and steam reservoirs.  The start-up vessel can thus be used not only in a start-up operation but as a mixing tank, a water storage tank and a level control at low loads for controlling feedwater flow.
