Title: Composition and method for treatment of otitis media
Inventor: MAUTONE ALAN JOSEPH
IPC: A61K47/24
Filed: 2000-08-28
Abstract: The present invention discloses a method of increasing and enhancing mammalian eustachian tube lumen patency and pressure equalization performance by administering an aerosolized mixture of lipid crystals comprised of a mixture of one or more lipids surfactants and one or more spreading agents selected from the group consisting of cholesteryl esters, phospholipids, carbohydrates, and proteins, in powder form, and one or more fluorocarbon propellants through a mammalian nasal orifice. Upon administration, the propellant(s) are evaporated from the mixture and the lipid crystals are deposited at a subject mammalian eustachian tube whereupon said lipid crystals come into contact with lumen surfaces of the tube forming an amorphous spread film thereupon substantially decreasing the opening pressure of the lumen. In a second preferred embodiment, a therapeutically active agent effective in the treatment of otitis media is added to the mixture of lipid crystals and upon administration of said aerosol mixture, the amorphous spread film formed thereby carries said therapeutically active agent through the eustachian tube to the tissues of the middle ear.

Abstract: A foot pedal lift system is provided for the mower deck of a lawn or garden tractor. The foot pedal is pivotally mounted to the frame of the tractor and is linked to the linkage arms which suspend the mower deck from the frame.      The pedal is movable between a depressed forward position to raise the mower deck to a transport position and a retracted rearward position to move the mower deck to a lower removal position. The pedal can be locked in the depressed or retracted positions by a latch pivotally mounted on the exterior of the tractor console. Engagement and disengagement of the latch with the foot pedal is controlled by a handle mounted on the console connected to the latch by an elongated connecting rod. Pulling upwardly on the handle locks the latch into engagement with the foot pedal in both the depressed and retracted positions. Pushing downwardly on the handle disengages the latch from the foot pedal so that the mower deck is free to move upwardly or downwardly.

Title: Access probe acknowledgement with collision detection
Inventor: HOFFMAN JOHN E
IPC: H04L12/56
Filed: 2001-02-23
Abstract: In an illustrative embodiment of the present invention, a first channel is allocated for transmitting sporadically generated messages from multiple field units to a base station. The first channel is preferably divided into time slots in which a field unit transmits an access request message to the base station for establishing a communication link. In response to an access request message, feedback information is provided from the base station to multiple field units indicating whether a collision was detected on the first channel for a message transmitted in a previous time slot. In an instance when a collision is detected, the field unit will re-transmit an access request message at a previous power level setting based on a random back off time. If no collision is detected and the base station fails to transmit an acknowledgement message from the base station to the access requesting field unit, the power output level of the field unit is increased for successive message transmissions until the message is received.

IPC: E21B10/32
Filed: 2003-01-23
Abstract: A downhole tool is disclosed that functions as an underreamer, or alternatively, as a stabilizer in an underrearned borehole. An embodiment of the tool includes one or more moveable arms disposed within a body having a flowbore therethrough in fluid communication with the wellbore annulus. The tool alternates between collapsed and expanded positions in response to differential fluid pressure between the flowbore and the wellbore annulus. In one embodiment, the tool moves automatically in response to differential pressure.  In a second embodiment, the tool must be selectively actuated before it is moveable. When the tool expands, the arms are preferably translated axially upwardly, while simultaneously being extended radially outwardly from the body. The expanded tool diameter is adjustable at the surface without changing components. The arms may include borehole engaging pads that comprise cutting structures or wear structures or both, depending upon the function of the tool.

Title: Further cooling of pre-swirl flow entering cooled rotor aerofoils
Inventor: PATEL KIRITKUMAR
IPC: F01D5/08
Filed: 2001-12-13
Abstract: A tangential on board injector with auxiliary supply of further cooled compressed air, from an external heat exchanger or air cooled bearing gallery for example, serves to reduce the volume of cooling air directed tangentially toward a cooled rotor of a gas turbine engine. The tangential on board injector has an array of injector blades (21) between two injector walls defining circumferential main flow nozzles for directing a main compressed air flow tangentially. Each blade has an interior chamber (25) in flow communication with a source of auxiliary compressed air with at least one bore (27, 28) extending between the chamber and an exterior surface of the blade.  The bores eject further cooled air from the heat exchanger and merge with the primary compressed air flowing through the injector nozzles. The bores (27, 28) may also produce a cooling film of air that reduces drag over the injector blades. Advantages of the further cooling bores (27, 28) include: reduction in injector air temperature and corresponding reduction in cooling air flow requirements; added control over injector flow volume and temperature to fine tune the delivery of cooling air to the rotor blades; improved cooling air control results in extended durability and service life of air cooled rotor blades; and the ejection of air near the trailing edge of the injector blades results in less drag and air pressure requirements.

Inventor: LENNOX JOHN A
IPC: H01M8/00
Filed: 2002-05-27
Abstract: A fuel cell powered magnetically driven shaft assembly comprises: a stationary fuel cell stack (12) having a hollow core; an electrically conductive sleeve (13) lining the hollow core so as to define a cylindrical passage therethrough; and a shaft (14) extending through the sleeve passage and rotatable about the longitudinal axis of the shaft. The shaft is embedded with one or more magnets configured to produce a magnetic field extending substantially perpendicularly to that longitudinal axis. Anodes of the fuel cell stack are connected to one end of the sleeve and cathodes are connected to the other end so as to provide a path for conducting electrons (28) through the sleeve constrained in a direction parallel to the longitudinal axis.  Because the current flows perpendicularly through the magnetic field, an electromagnetic force is produced in a direction which is tangential to the shaft, causing the shaft to rotate about its longitudinal axis.
