Abstract: ABSTRACT     PERFUSION TYPE BALLOON DILATATION CATHETER            AND APPARATUS       Perfusion-type balloon dilatation apparatus having a guiding catheter with proximal and distal extremities and with a flow passage extending therethrough.  A balloon dilatation catheter is disposed in the guiding catheter. The balloon dilatation catheter is comprised of a flexible elongate tubular member having proximal and distal extremities and having a first lumen extending therethrough. First and second inflatable balloons are carried by the tubular member and having their interiors in communication with the first lumen in the tubular member.  The first balloon is positioned within the guiding catheter.  The second balloon is positioned adjacent the distal extremity of the tubular member.  A second lumen is carried by the tubular member and extends through the first and second balloons and through the distal extremity of the tubular member.  The second lumen has an opening proximal of the first balloon and opens into the interior of the guiding catheter.  An adapter is carried by the proximal extremity of the guiding catheter and provides a liquid-tight seal between the guiding catheter and the dilatation catheter and also provides an inlet through which liquid can be introduced so that it can travel through the flow passage in the guiding catheter and into the second lumen carried by the dilatation catheter so that the liquid can flow through the second lumen beyond the second inflatable balloon.

IPC: H04L12/56
Filed: 1988-06-28
Granted: 1992-03-24
Abstract: Abstract of the Disclosure A copy network capable of packet replication is disclosed. An encoding process transforms the set of copy numbers, specified in the headers of incoming packets, into a set of monotone address intervals which form new packet headers.  This process is carried out by a running adder network and a set of dummy address encoders.  A broadcast banyan network performs the packet replication according to a Boolean Interval Splitting Algorithm. Finally, trunk number translators determine the destinations of individual copies.  The copy network is self-routing, non-blocking and has a constant packet latency.

Granted: 1994-11-08
Abstract: A refrigerating system including a refrigerant circuit having a condenser, evaporator and wobble plate type compressor with a varia-ble displacement mechanism. Two passages communicate between the crank chamber and the suction chamber in the cylinder block. A bellows is disposed in a first passage and controls the communication between the crank chamber and the suction chamber response to crank chamber pressure. A control valve is disposed in the second passage and controls communication between the crank chamber and the suction chamber in the second passage in response to a signal gen-erated outside of the compressor. A control circuit controls the gen-eration of the signal in response to thermodynamic characteristics related to the evaporator. The signal activates or deactivates the second control valve when the characteristic indicates a value beyond a predetermined range of values. This configuration enables the com-pressor to obtain better cool down characteristics in the passenger compartment of an automobile.

Abstract: DEVICE AND METHOD FOR MONITORING ALIGNMENT        UTILIZING PHASE CONJUGATION           ABSTRACT Monitoring alignment of an element(s) is accomplished with a source of radiation (11), an alignment reflecting assembly (12) embedded within or attached to an element (13) whose alignment is to be monitored and a detection assembly (14). Alignment reflecting assembly (12) includes a conventional mirror (16) that reflects a portion of the incident radiation (E) at a reflection angle that is substantially equal in magnitude and opposite in sign to that of the angle at which the incident radiation is incident thereupon.  Alignment reflecting assembly (12) also includes a phase conjugate mirror (18) that reflects incident radiation (E) at a reflection angle that is substantially equal in magnitude and sign to that of the angle at which the incident radiation is incident thereupon, i.e., along the path of the incident radiation.  The alignment orientation of alignment reflecting assembly (12) and element (13) is determined by monitoring the so-called retro-reflected radiation from the phase conjugate mirror (18) and the reflected radiation from the conventional mirror (16).

Title: Aircraft aircrew life support systems
Inventor: STEVENSON GEORGE F
IPC: A62B9/02
Filed: 1988-12-13
Granted: 1992-03-17
Abstract: ABSTRACT     Title:  Aircraft Aircrew Life Support System An aircrew life support system has an on-board oxygen generating system (OBOGS) connected for delivering oxygen-enriched product gas to a breathing demand regulator and a plenum storage container.  The concentration of oxygen in the product gas is sensed by a gas concentration sensor which supplies signals to an electronic control unit (ECU).  The ECU outputs signals for switching a control valve which controls product gas to be delivered to the regulator from either the OBOGS or the storage container. The ECU also outputs signals to a charge valve which is opened to allow product gas from the OBOGS to charge the storage container when product gas enriched with oxygen above a predetermined concentration is being delivered by the OBOGS and there is excess capacity over the demand requirements at the regulator. The breathing demand regulator provides for mixing of the OBOGS product gas or of the stored gas with cabin air to provide a breathing gas matched to physiological requirements under all operational conditions, both normal and emergency and, especially to provide for long-term sea level breathing from the stored gas when the OBOGS is not operating.

Abstract: ABSTRACT OF THE DISCLOSURE        An improved method for the continuous fabrication of metal-hydride, electrochemical, hydrogen storage alloy, negative electrodes for use in rechargeable nickel metal hydride cells.  The improved method comprises the steps of providing measured amounts of powdered metal hydride electrochemical hydrogen storage alloy material and disposing said material upon a continuous wire mesh screen substrate.  Thereafter, the powdered metal hydride electrochemical hydrogen storage alloy and wire mesh screen are subjected to a compaction process wherein they are rolled and pressed so as to form a single integral electrode web which is subsequently exposed to a high temperature sintering process in a chemically inert environment.  The sintering process is designed to drive off excess moisture in the material while discouraging oxidation of the electrode web and set the electrode web state of charge.   0149r

Individual windows are selected by the user and altered  in their  display  mode  attribute  to  temporarily render the interior or background transparent.  This process is repeated until such time as the visually obscured data is visible.  Thereafter, the user may return to a second window while retaining any or all of the remaining windows in the modified display attribute mode.  In a preferred embodiment of the present invention,  the user may temporarily render the  border  of  any window transparent  in  the  event  that border is obscuring the desired data.
