Abstract: A DUPLEX DIGITAL SPAN CONVERSION CIRCUIT ARRANGEMENT    ABSTRACT OF THE DISCLOSURE In a telecommunications switching system, a thick film digital span conversion circuit is con-nected between a digital span and a switching network of the switching system.  The circuit converts data, which is encoded for digital span use, to TTL logic coding for use by the switching network.  The tele-communications switching system provides for dupli-cated data transmission through the switching network. Duplicated conversion circuits are employed in an active/standby configuration under CPU control,  On-line replacement of a fault conversion circuit may be performed without a switching service interruption.

Abstract: Abstract of the Disclosure A tintable abrasion-resistant coating is formed on a substrate such as a lens or other optical article by applying a radiation-curable coating to the surface of the substrate and partially curing the applied coating by exposure to radiation so as to produce from about 20% to about 80% cross-linking in the coating. The exposure to radiation is terminated when the coating is partially cured to provide a coated article which is tintable but capable of being handled for shipping to a retail finisher or the like for tinting and then completion of the cure by exposure to radiation. Preferably, a radiation-curable coating comprising a triacrylate or tetracrylate monomer and a monomer containing an N-vinyl imido group is applied to a substrate comprising polycarbonate, polyallyldiglycolcarbonate, or acrylic polymer.

Abstract: SOUND ABSORPTIVE STRUCTURAL BLOCK      WITH SEQUENCED CAVITIES            Abstract of the Disclosure A sound absorbing block of molded structural material has a sequence of internal cavities that communicate with a region containing the sound to be suppressed through a first elongated slot located in an exterior wall of the block.  The internal cavities are defined by interior walls, at least one of which also contains an elongated, sound-communicating slot.  Each slot and its associated cavity define an acoustical Helmholtz resonator that dissipates sound energy incident upon the slot with an absorption peak at a natural frequency fn.  The value of fn for each resonator is inversely proportional the square root of the volume of the cavity.  The internal cavities are arranged to cascade in order of decreasing stiffness beginning at the first slot.  In one form, two sequences of cavities in a block use a common final cavity.  Also, the exterior slots can be formed in more than one wall to absorb sound produced in multiple regions.

Abstract: PULVERIZED COAL RELATIVE DISTRIBUTION METER                  ABSTRACT OF THE DISCLOSURE            An apparatus for measuring the relative flow of pulverized coal in a plurality of pipes connected between a common pulverizer and respective burners comprises a plurality of electric charge sensors each disposed in a similar position on the plurality of pipes.  The electric sensors sense an induced signal produced by charged pulverized coal particles.  For unbiased flow, the induced signal is proportional to the amount of flow in each pipe as the charge properties of the particles from the pulverizer are the same for all the pipes.          A circuit is connected to the sensors for obtaining a root means squre value of the induced signal which in turn is compared to each induced signal respectively to obtain a measurement of the relative flow in each pipe.  The induced signal can be integrated twice to improve the correlation between flow and charge amount since the integrated value is independent of radial position for the charges in the pipes.

BARDSLEY   ABSTRACT OF THE DISCLOSURE          An optical  scanner/pulse  iniator  used for  deriving power consumption data from a power meter has a pair of light sources modulated by a square wave having a repetition rate R and an OFF period P.  The light beams produced by the light sources are positioned to reflect off of spatially separated points on the rotor  (disc)  in a power meter so that as the rotor  rotates a non-reflective stripe will block  the  light beams one after the other.  A first light sensor is positioned to receive the first light beam after being reflected off the rotor and provides an output signal indicating when the first beam is OFF for a period of  time that greater  than P.   A second light sensor is positioned to receive the second light beam after being reflected by the rotor and it also provides an output signal indicating when the second beam is OFF for a period of time greater than P.  An output circuit receiving the output signal indications from first and second sensors provides an output pulse upon receiving an  indication  from each  of  the  first  and  second  light  sensors.   And,  the accumulation of these pulses  is  the power  consumption data required.

Abstract: ABSTRACT OF THE DISCLOSURE    Both a metering valve and a valve assemblage for controlling the administration of IV fluids having a valve housing with a valving chamber therein are provided herein.  The valve includes a housing defining a valving chamber, the housing including an inlet and an outlet connectable to the tubing and placing the chamber in the fluid flow path.  A metering member is rotable within the valving chamber, the housing and the metering members being formed of synthetic plastics materials of different hardnesses, as represented by different Shore hardnesses.  The valving chamber and the metering member engage in an interference fit as a consequence of the different hardnesses of the synthetic plastics materials.  They thus provide a first regime providing a flow passageway in which the cross-sectional area varies over its length; a second regime providing a flow passageway of substantially uniform area over its length for establishing a purge flow condition; and a third regime in which there is no flow passageway and fluid flow is blocked.  Means are provided for rotating the metering member relative to the valving chamber to establish one of the regimes, thereby to achieve varying of the flow rate through the flow passageway or the blocking of flow.

Abstract: VOLUMETRIC FLOW RATE DETERMINATION IN CONDUITS NOT DIRECTLY ACCESSIBLE            Abstract A catheter, particularly adapted for cardiac output determination, comprises an elongated tube of flexible material, the tube having a substantially rigid distal portion on which is disposed an ultrasonic transducer and a proxi-mate; inflatable balloon. The ultrasonic transducer is arranged so as to direct a beam of ultrasound toward a transverse plane that bisects the balloon, and is connected by appropriate leads to a conventional Doppler circuit. With the balloon deflated, the signal from the Doppler circuit is sensed to measure bloodvelocity. Thereafter, the balloon is inflated so that it has a predetermined cross-sectional area in the transverse plane. The signal from the Doppler circuit is again sensed to measure blood velocity. Using a simple mathematical relationship, the effective internal cross-sectional area of the blood vessel isdetermined from the two measured velocities and from the predetermined cross-sectional area of the balloon when inflated. The volumetric flow rate is then determined by multiplying the first measured velocity by the effective internal cross-sectional area.

Abstract: ABSTRACT        In a copolymerization process of propylene, a mixture of unreacted propylene and ethylene is recovered.  It is then fed to a distillation system which includes first and second distillation columns.          The distillation system is operated in such a way that the temperature and pressure of the top of the second distillation column remain constant and an ethylene-propylene mixture can be recovered at a constant ethylene/propylene ratio from the top of the second distillation column.  By using the thus-recovered ethylene-propylene mixture, the copolymerization reaction can be carried out under excellent control so that the ethylene/propylene copolymer can be obtained with uniform quality and properties.
