Abstract: Case 04-4241-U.S.                      APPLICATION OF                    ROGER D. ERICKSON                ELECTROGRAPHIC RECORDING                   ABSTRACT   An electrographic recording system includes means wherein toner powder having electrical and magnetic properties is carried from a hopper to a recording station by a rotatable drum or shell.  The shell is rotated about a magnetic core structure which produces a magnetic field to hold the toner powder onto the surface of the shell as it rotates.  At the recording station, a dynamic bridge is formed of the toner powder between the periphery of the drum and a magnetically permeable member positioned a predetermined distance from the surface of the drum.  A record member is driven along a path between the drum and the permeable member with the reverse side of the record member in contact with the permeable member.  An array of recording electrodes are positioned to be in electrical contact with the toner powder in the bridge.  The record member is backed up by an electrically conductive platen.  When one or more of the electrodes is energized a conductive path is established from the electrode through the bridge to the surface of the recording member and the conductive backup plate, electrically charging the dielectric surface of the recording member to deposit toner thereon.

Abstract: BEVELING APPARATUS               ABSTRACT OF THE DISCLOSURE           Apparatus for quickly and efficiently beveling the edges of a workpiece such as a sheet of glass having at least two pairs of parallel sides, generally a square, without manual intervention during the process.  The workpiece is positioned on a conveyor with the first pair of parallel sides parallel to the direction in which the conveyor moves the workpiece.          Guides are provided for maintaining the angular orientation of the workpiece.  The workpiece is conveyed sequentially through: a first grinding apparatus which grinds the first pair of parallel edges; a first turntable which rotates the workpiece through a precisely controlled angle to position the second pair of sides parallel to the direction of transport; a second grinding apparatus which grinds the second pair of parallel edges; a first polishing station which polishes the second pair of edges; a second turntable which rotates the workpiece through a precisely controlled angle so that the first pair of edges is again parallel to the direction of transport; and a second polishing station which polishes the first pair of edges.          Coolants, lubricants, and polish are sprayed on the workpiece as necessary.  The position of the grinders and polishers with respect to the conveyor are adjustable such that the angle and depth at which the workpiece edges are ground and polished can be selected.  In addition, these adjustments permit compensation for wear of the grinding wheels and polishing wheels.  The polishers further include ammeters connected to their motors which indirectly measure the pressure exerted on the workpiece by the polishing wheel.  The turntables are pneumatically operated so as to lift the workpiece from the conveyor, rotate the workpiece through a precisely controllable angle, and return the workpiece to the conveyor in a short period of time. Other configurations of grinders, polishers, and turntables are also contemplated.

Abstract: MECHANICAL SECTOR SCANNER HEAD AND POWER TRAIN            Abstract A curved faced, disc shaped transducer and an oppositely facing, circular angularly disposed mirror form the trans-mission and reception path of a mechanical sector scan imaging system.  The transducer and mirror are mounted on a common axis, and a shaft upon which the mirror is affixed oscillates about that axis.  Through a belt drive mechanism, a motor provides the oscillating motion, in turn scanning the ultrasound beams through the subject by virtue of the mirror motion.  An optical encoder records positional information from the motor, for coordination of the mirror oscillation with transducer signals, and there-by for the assembly of a composite image.

Abstract: MICROBENDING OF OPTICAL FIBERS           FOR REMOTE FORCE MEASUREMENT              ABSTRACT OF THE DISCLOSURE          A system for remote measurement of structural forces includes  a plurality of microbend  transduc-ers mounted along the length of the structure for micro-bending  an optical  fiber  in response to structural forces, such as stress acting upon an oil or gas pipeline or  the like.   An optical time domain reflectometer (OTDR) has a light source for launching a pulsed optical signal for passage through the fiber and a photodetector for sensing as a function of time the intensity of backscattered  light  reflected  back  through  the  fiber, wherein this sensed time function is correlated directly with discrete longitudinal positions along the length of the fiber and the structure.   When one or more of the microbend transducers is activated to induce a microbend in the fiber in response to localized forces acting upon the structure, a portion of the backscattered light is lost at the microbend.  This attenuation in backscattered light intensity is sensed quantitatively and positionally identified by the photodetector.  Specific preferred constructions  for  microbend  transducers  and  system arrangements particularly adapted for detecting structur-al strain in an oil or gas pipeline are disclosed.

Stefanovic ABSTRACT OF THE DISCLOSURE         The multilevel inverter includes a voltage divider which when connected across a dc source ED, provides voltage at terminals having values between +ED to -ED.  A first and a second set of thyristors pairs are connected between the positive or negative terminals, respect-ively, and a load terminal for applying selected voltage levels to the load.  Any thyristor pair in these sets may be turned-off by firing the thyristor pair at the next highest voltage level.  However, the main thyristors which are connected to the +ED or -ED terminal is turned-off by a commutation circuit.  This circuit includes a single capacitor maintained at zero voltage and subjected to an oscillating voltage during the commutation cycle to turn-off the conducting main thyristor.  Such an inverter can easily provide a waveform having a series of pulses at one or more voltage levels thereby eliminating harmonics in the output.

Granted: 1985-04-02
Abstract: A B S T R A C T          Ethylenediamine tetraacetic acid is prepared by forming an ethylene-diamine formaldehyde adduct, cyanomethylating the adduct with hydro-cyanic acid at controlled temperatures to form ethylenediamine di-acetonitrile. This is further cyanomethylated under acid conditions with formaldehyde and hydrocyanic acid in slight excess to form the ethylenediamine tetraacetonitrile. The precipitated product, with or without isolation, is hydrolyzed to form the tetrasodium salt of the ethylenediamine tetreacetic acid in a stock solution for further processing. The process, in semi-batch processing, provides yields above about 98% and in good purity.            When combined with ethylenediamine tetraacetic acid production, the process eliminates the need for cyanide waste treatment and greatly simplifies the procedures needed to protect the environment.
