Abstract: A HIGH CAPACITY DIGITAL   MOBILE RADIO SYSTEM            Abstract of the Disclosure The present invention relates to a mobile radio base station capable of communicating with a large number of mobile stations by implementing space diversity and time-division retransmission techniques in a digital communication system.  The digital base station contains a plurality of antenna elements and a plurality of retransmission branches associated in a one-to-one relationship.  When the base station receives a digital communication signal from a mobile station, each antenna element receives the signal with a unique random phase due to the effects of the environment on signal transmission. The signal is then processed through the plurality of retransmission branches, where each branch adapts to compensate for the random phase of the signal received by its associated antenna element.  Conversely, when the base station transmits a signal back to the mobile station, each retransmission branch adds the conjugate of its associated random phase to the signal to be transmitted, allowing the environment to "undo" the effect of the conjugate random phase so that the signals transmitted by the plurality of antenna elements will arrive coherently at the mobile station.

Abstract: ALKYL-SUBSTITUTED POLYMERS HAVING ENHANCED           ALBUMIN AFFINITY            ABSTRACT       Methods and compositions are provided for selectively enhancing the affinity of albumin for the surface of polymeric materials.  Reactive non-ionic, hydrophobic aliphatic chains, in particular C14 to C20 straight chained aliphatic hydrocarbon moieties are covalently attached directly to polymeric materials such as polyamides, polyesters, polyacrylamides, and poly-urethanes.  Reactive aliphatic compounds include alkyl halides, alkyl sulfonates, alkyl isocyanates, and alkyl amines.  Al-ternatively, intermediate bifunctional arms, e.g. toluene-diisocyanate, can be used to link the alkyl chains to the meric polymer precursors which, following polymerization, axe available for albumin binding without postpolymerization modification. The resulting compositions when implemented in conjunction with blood products selectively enhance albumin surface affinity-binding to the exclusion of other blood components, and subsequent thrombus formation is prevented.

Abstract: M. H. November 21 MASS FLOWMETER OR THE LIKE                  ABSTRACT OF THE DISCLOSURE A quartz tuning fork in a chamber adjacent a gas pipeline carrying a turbine flowmeter.  The chamber is connected across the flowmeter turbine to receive a gas at a flow rate high enough to cause the tuning fork to vibrate.  A main output frequency is developed which is directly proportional to the product of a function of the tuning fork period of vibration and the turbine meter output signal frequency.  The main output frequency is then counted and is displayed on an indicator, the constants of the circuit being so selected that the indicator displays total flow in units of mass.  The density sensor measures the gas density at the turbine flowmeter rotor location.  This obviates the requirement for expansion factor corrections.

Abstract: METHOD FOR DETERMINING SOURCE AND RECEIVER   STATICS IN MARINE SEISMIC EXPLORATION          Abstract In a method for seismic exploration at a marine exploration site having an anomalous near surface low velocity layer 12 below the water bottom, a marine seismic detector cable 14 is deployed along a seismic exploration line for which seismic reflection signals traveling to said seismic detector cable 14 pass through the near surface low velocity layer 12.  In addition, a marine seismic monitor 15 is deployed at a distance remote from the seismic detector cable 14 such that the first energy received at the monitor 15 is in the form of seismic refraction signals which have passed through the near surface low velocity layer 12.         First seismic energy is then generated at an offset distance from the seismic detector cable 14 so as to produce a first seismic signal which travels downward into the earth, is refracted through the earth, and travels upward through the near surface low velocity layer 12 to intersect the seismic detector cable 14 in a generally orthogonal direction, whereby said first seismic signal, as received by the detector cable 14, includes a receiver statics component attributable to said near surface low velocity layer.  The first seismic signal is then compared with recorded refraction data for non-low velocity layer areas to determine said receiver statics component.         In addition, second seismic energy is generated so as to produce a second seismic signal which travels downward through the near surface low velocity layer 12 into the earth, is refracted through the earth, and is detected by the remote seismic monitor 15 whereby said second seismic signal, as detected by the remote monitor 15, includes a source statics component attributable to the layer 12.  The source statics component is determined by comparing the second refracted signal with the reflected signal detected by the cable 14 in response to reflection of the second seismic energy from the earth.
