Title: Catheter for effecting removal of obstructions  from a biological duct
Inventor: STILES FRANK B
IPC: A61B17/22
Filed: 1984-03-09
Granted: 1988-05-31
Abstract: ABSTRACT             A catheter for insertion into a biological duct such as an artery, comprised of a flexible aspiration tube disposed within a delivery sleeve and connected at one end to a source of vacuum for providing suction within the duct in the vicinity of a biological obstruction, such as a blood clot.  An injection tube extends through the aspiration tube for injecting medication into the duct, and an ultrasonic energy source also extends through the aspiration tube for transmitting ultrasound in the vicinity of the obstruction.  The transmitted ultrasound and injected medication cooperate to emulsify and fragment the obstruction, and the fragmented obstruction is removed through the aspiration tube in response to suction being applied thereto.  The catheter is compact and easily manipulable, providing substantial surgical accuracy.

Abstract: -22-            RCA 79,481 Abstract of the Disclosure A television signal processing system includes circuitry for performing hue control by effective rotation of the axes of the color mixture signals.  The system includes a source of first and second quadrature related digital color mixture samples.  Both the first and second color mixture samples are applied to multiplying means. The sines and cosines of the angle by which the axes are to be rotated are also applied to the multiplying means. The multiplied first and second color mixture samples are applied to a combining means. The combining means combines both the multiplied first and second color mixture signals to form modified first and second color mixture samples which form a rotated set of axes.

Abstract: ABSTRACT A system for testing seismic signal recording equipment wherein a test signal is generated which simu-lates the output of at least one seismic sensing device, and, thereafter, the test signal is applied to the seismic signal recording equipment.  The test signal is recorded by the seismic signal recording equipment and the recorded signal is compared with the generated test signal to eval-uate the performance characteristics of the seismic signal recording equipment.  The system can include circuitry to vary component elements of the test signal to test dif-ferent performance characteristics of the seismic signal recording equipment, as well as ability to generate a random noise signal for addition to the test signal.

Abstract: ABSTRACT OF THE DISCLOSURE     A number of elongate articles such as slide fasteners are placed on a length of a band web supplied on a bundle tray.  Free and opposite ends of the length of the band web are gripped by a gripper mechanism with the length surrounding the elongate articles.  End portions of the length are then ultrasonically fused together by an ultrasonic horn and an anvil.  The opposite end of the length as it is gripped by the gripper mechanism is cut off by a cutter mechanism to form a band bundling the elongate articles.  The elongate articles-bundled by the band are then discharged by the bundle tray.  The invention improves the uniformity of the bundling of the articles and provides a successive, automatic bundling thereof.

Abstract: ABSTRACT         FIELD INSTALLABLE MODULAR TELEPHONE CONNECTOR           An electrical connector for use as a telephone plug or jack is assembled without need of special tooling and comprises a housing for receiving an insert member The insert member supports a plurality of contacts thereon, each contact having a first end for external connection to the contacts of another jack or plug and a second end por-tion of insulation-displacing type.  A conductor support element secures telephone cable conductors therein and is engaged with the housing to place the conductors in insu-lation-displaced engagement with the contact second end portions.  A twenty-five pair telephone connector utilizing a modified version of the jack includes, in its preferred form, a base having first and second pluralities of com-partments separated by a fold section.  The fold section defines a channel for receipt of conductors of a multi-conductor telephone cable.  The folded base places the jack housings in abutting relation for retention therein, securement means holding such base in its closed, folded condition.  Excessive electrical interfacing with attendant disadvantage in electrical resistance is thereby reduced.

Abstract: ABSTRACT OF THE DISCLOSURE:         A central control unit (scanner) is connected across a set of subscriber loops.  At each subscriber's premises, an individual subscriber terminal unit (STU) is connected across that particular subscribers loop.  To each STU are connected the various instrumentalities which are to be monitored by the system, e.g. fire alarms, burglar alarms, etc.  A signal below the audible range (low tone) is produced at the STU, and transmitted to the scanner over the telephone loop if, but only if, all the instrumentalities at the particular subscriber premises are in a given state (e.g. non-alarm).  If not, low tone is stopped.  Such stoppage is sensed by the scanner, and causes immediate transmission of FSK modulated signals in the upper part of the audible range from the scanner to the corresponding STU, whether the associated telephone is on-hook or off-hook at the time.  The reply from the STU to such transmission provides information about the reason for the stoppage, i.e. what is the source of the alarm.

Abstract: ABSTRACT OF THE INVENTION     A vacuum feed mechanism for precision feeding a printed continuous double-backed corrugated paper board web to a platen die cutter for producing printed foldable box blanks.  The feeder has several adjacent horizontal endless belts, with each belt having spaced cleats extending over the width of the belt facing outward and a row of holes between each cleat.  A vacuum plenum extends through each belt with a lower wall containing longitudinal slots in registration with the bell holes.  A suction fan removes air from the vacuum plenum producing air flow from the edges of the belts between adjacent cleats, through the belts and into the vacuum chamber to draw the belt into contact with the plenum chamber wall and the web in contact with the belt cleats, holding the web without slippage while the web is intermittently fed to the platen die cutter.  The belt advancing mechanism utilizes separate drive pulleys for each belt keyed to a common shaft and separate idler pulleys freely rotating on another common shaft providing minimum inertia and permitting rapid starting and stopping of the belts for synchronized feeding of the web to the platen die cutter.

The prefetch control unit may reduce the prefetching of write commands stored In the first memory after the receipt of the first EWA signal.  Preferably,  the prefetchings of write commands may be reduced when a write command sent from the host system is received.     After the prefetch control unit receives the first EWA signal, the number of prefetched write commands is limited, the  final limit being determined by the recording density and the maximum block length of the write commands.     The running distance of the magnetic tape may be calculated and prefetch control performed until the cal-culated value reaches a value corresponding to a second EWA position corresponding to a position before the end marker of the magnetic tape. When the value corresponding to the second EWA position  is reached, an EOT signal is issued to the host system and prefetchings of write commands from the host system are no longer accepted.
