Title: Endoscopic ultrasonic aspirator with modified working tip
Inventor: WUCHINICH DAVID G
IPC: A61B10/02
Filed: 1986-08-19
Granted: 1992-07-07
Abstract: ENDOSCOPIC ULTRASONIC ASPIRATOR   WITH MODIFIED WORKING TIP                  ABSTRACT OF THE DISCLOSURE     A method and apparatus for endoscopic removal of compliant biological tissues utilizing an endoscopic ultrasonic aspirator comprising irrigation and aspiration means, a piezoelectric ultrasonic transducer, a first resonator such as a half-wave stepped velocity transformer, a probe including a second resonator such as a constant-stress velocity transformer, a blunt or modified working tip of open channel means or restricted tubular means for application of ultrasonic energy to cellular material, and a capacitive fluid sensor to detect the presence of irrigation fluid adjacent these transformers within the instrument.          The surgery is advantageously performed by operating the transducer in the 10-20 kHz range to achieve maximum cavitation of the intracellular fluids in the tissues to be removed.

Title: Video cassette recorder adapter
Inventor: DAMOCI JOSEPH A
IPC: H04N7/16
Filed: 1986-09-30
Granted: 1991-01-22
Abstract: ABSTRACT OF THE DISCLOSURE An adapter for metering tv viewing in homes having video cassette recorders ("VCR's").  The adapter disables antenna (cable) input to the VCR except when in the record mode.  Record mode is detected by a probe which detects the 70 MHz erase signal of the erase heads.  When in record mode, antenna input to the VCR is enabled and a tv meter determines channel tuning.  A band-pass filter on the VCR video output restricts the tv's ability to tune channels other than the VCR output.  If the tv is tuned to the VCR output channel, the viewer is monitoring the program being recorded or watching a prerecorded tape.  Otherwise, he is tuning through the normal antenna (cable) input and a meter determines the tv's channel tuning.

Title: Sewing needle with easy-threaded filament loop
Inventor: FEUERMAN ARNOLD I
IPC: D05B87/00
Filed: 1987-03-05
Granted: 1992-05-12
Abstract: ABSTRACT OF THE DISCLOSURE          A sewing needle has a main body 10 and a closed loop 18 of a resilient filament material rigidly secured to the rear end of the main body and lying a single common plane with the lengthwise axis of the main body.  In unstressed condition,  the filament has an open diamond configuration allowing a sewing thread to be easily passed through it.  As the needle is pulled through the fabric, the loop collapsed under the forces imposes on its sides by the fabric and thereafter expands to reassume its unstressed configuration.  The rigid securement of the loop to the main body of the needle ensures that the loop remains in a single common plane with the needle axis as it collapses upon passage through the fabric and as it expands to its unstressed configuration following such passage.

Abstract: Abstract of the Disclosure In a dot matrix line printer in which a plurality of hammer springs mounted along the length of an elongated reciprocating hammerbank are selectively released or fired to impact dot printing impact tips mounted thereon against a print paper through a length of ink ribbon to print dots, the wear that would otherwise occur each time one of the hammer springs rebounds back into contact with a pair of pole pieces against which the hammer spring resides when in its retracted position is greatly minimized by chromium masses plated on the tip of the hammer spring and on the tips of the pole pieces.  Chromium platings on each hammer spring are confined to the end of the spring and comprise either a pair of masses adjacent the different pole tips or a single mass encompassing both pole tips.  The chromium masses are of convex contour and of hexavalent chromium composition to provide the masses with hard and smooth surfaces that slide over and do not abrade one another upon impacting.

Title: Multi-level quadrature apmlitude modulation and demodulation system
Inventor: YAGI TAKESHI
IPC: H04L25/49
Filed: 1988-08-26
Granted: 1992-02-11
Abstract: ABSTRACT    A multi-level quadrature amplitude modulation and demodulation system includes a first exchange circuit for cyclicly exchanging input digital signals and for outputting exchanged signals to D/A converters.  The D/A converters provide analog signals to a QAM modulator which produces a modulated signal.  In the receiver side of the system, a QAM demodulator demodulates the modulated signal to produce analog signals which are converted to digital exchanged signals by A/D converters.  The digital exchanged signals are exchanged in a manner which is the reverse of that of the first exchange circuit to provide output digital signals on output terminals which respectively correspond to the input terminals.   By cyclicly exchanging the input signals in this manner, the transmission quality for each of the input signal channels is maintained equal.
