Abstract: APPARATUS FOR GENERATING BI-PHASE CODED CHARACTERS                    ABSTRACT OF THE DISCLOSURE     Apparatus for generating bi-phase coded characters formed of a predetermined number of bi-phase signals representing binary bits "1" and "O" having a constant relation between the phases at the beginning and end of each coded character regardless of the number of "1"s and "0"s included in the coded character.  A source of binary bits  supplies trains of serial bits corresponding to the coded characters, these serial bits being supplied to a bi-phase signal generator which is responsive to each bit for generat-ing a respective bi-phase signal.  A binary bit of predetermined sense is supplied in time coincidence with a selected one of the bits in each coded character; and this bit of predetermined sense is selectively inserted into the train of binary bits which is supplied to the bi-phase generator, thereby maintaining the constant relation between the phases at the beginning and end of the bi-phase coded character generated by the bi-phase signal generator.  In a preferred embodiment, the coded characters are SMPTE time code characters, wherein a binary "1" bit is represented by a level transition at the beginning of the bit period and another level transition during that bit period, while the binary "O" bit is represented by a level transition only at the beginning of the bit period.  The bi-phase SMPTE time code character which is generated by the apparatus of this invention has a level transi-tion at the beginning of the character which is of the same sense, or polarity, as the level transition which is provided at the end of that character.                       -i-

Abstract: ABSTRACT OF THE DISCLOSURE         A butterfly valve, suitable for use with cryogenic fluids, has a disk with a spherical sealing surface having an axis of rota-tion displaced relative to a plane through the spherical sealing surface.  The sealing surface cooperates with a sealing ring disposed and retained in an internal groove in a valve body provided between a circular seat in a wall of the valve body and a retaining ring which is pressed against the sealing ring by appropriate means in order to hold the sealing ring in place.  The internal groove is under cut and exhibits a radial, inwardly open slot through which a radial, inwardly-projecting sealing lip on the sealing ring extends to co-operate with the disk's sealing surface when the disk is in the closed position.  The sealing ring is of the type that is affected by spring pressure as well as fluid pressure, and has a substantially U-shaped cross section with the radial, inwardly-projecting sealing lip disposed at the middle portion of one U-leg, with a radial, outwardly-projecting flange extending from the lateral edge of the U-bottom.  The flange is retained in a circular space at the bottom of the groove between the retaining ring and the circular seat in the valve body, and a clamping ring of stainless steel is disposed between the legs in the U-shaped sealing ring for exerting a radial, inwardly-directed pressure on the sealing lip.  The clamping ring has a U-shaped cross section, the bottom and legs of the U-shaped clamping ring being adjacent to the bottom and legs of the sealing ring and the U-bottom being displaced from a radial plane through the sealing lip.  The clamping ring comprises U-shaped members con-nected to one another in the circumferential direction of the clamping ring and movable relative to one another such that the circumference and diameter change and adapt to dimensional varia-tions which occur in the butterfly valve under variations of tempera-ture to which it is subjected.

Granted: 1982-04-27
Abstract: ABSTRACT OF THE DISCLOSURE         A system for priming liquid ink writing instruments such as ink jet writers and capillary ink pens is disclosed.          A source of ink is pressurized to force ink through the ink jet or other pen so that a small droplet is formed at the jet or pen outlet. As the drop forms at the jet or pen, it is eventually drawn away into an adjacent orifice, due to capillary action.  An integrated priming pump serves both to pressurize the ink source to form the ink droplet and to apply a vacuum to the orifice to remove the ink drawn away by capillary action.  A pressure release valve ensures that the ink jet or pen is not overpressurized during priming.   In ink jet applications, the drop removal orifice is formed as a portion of the droplet charging ring.

Abstract: ABSTRACT OF THE DISCLOSURE In polyvinyl chloride production plants air enters the process during production operations and must be vented to the atmosphere.  The air becomes mixed with gaseous vinyl chloride monomer during the process and not all of the vinyl chloride monomer can be condensed therefrom as liquid in the normal monomer recovery operation.  Consequently the vent gas stream contains appreciable proportions of vinyl chloride monomer along with air, and in many cases is saturated with water vapor.  In order to remove and recover the vinyl chlor-ide monomer from the vent gas before it is released to the atmosphere, the vent gas stream is treated counter-currently with a stream of liquid solvent which absorbs the vinyl chloride monomer and the vinyl chloride mono-mer is then stripped from the solvent by application of heat and condensed as liquid vinyl chloride while re-cycling the lean solvent to the absorption step.  The solvent used as the absorbent is a branched chain saturated aliphatic hydrocarbon containing 8 carbon atoms and composed predominately of 2,2,4-trimethyl pentane.  This solvent enables the vinyl chloride con-tent of the gases vented to the atmosphere to be reduced to less than 5 and even less than 1 part per million by volume.  Its use assures that any solvent vapors emitted with the vent gas are controllable so as to be not harmful to the environment.  Its use also assures that the normal steam supply at the plant will provide the heat necessary to strip the absorbed vinyl chloride monomer from the solvent.

Abstract: ABSTRACT             "Engine Speed Measuring System"     This disclosure relates to a system for measuring the instantaneous speed of an index point on a rotating part.  The part may be a toothed gear or a wheel of an engine, and the index point may be an identifiable point on the part.  The system comprises a sensor that is mounted adjacent the part, the sensor including two sensing elements that are spaced apart in the direction of movement of the point as the part rotates.  As the point passes the sensor, it causes a first pulse to be produced by one element and then a second pulse to be produced by the other element.  The system further includes  circuitry that responds to the two time-spaced pulses and produces an indication of the time interval between the two pulses.  This time interval is a func-tion of the speed of the point which in turn is pro-portional to  the rate of rotation of the part.  In the instance where the part is attached to an engine flywheel, the time interval is also an inverse function of engine RPM.
