Patent number: 8534286Abstract: An nCPAP device including a generator body defining first and second fluid flow circuits each including a tube and first and second nozzles. The tube defines a passageway forming an axial centerline. The first and second nozzles are associated with the tube and each defines an inlet and an outlet. The inlets are open to a fluid supply, whereas the outlets are open to the passageway. Each nozzle is adapted to emit a fluid jetstream from the outlet along a flow direction axis. The nozzles are arranged such that the flow direction axes are non-parallel relative to each other and relative to the axial centerline. This configuration readily induces vortex shedding during an expiratory phase, thus facilitating jet fluid flow disruption and reducing a patient's work of breathing.Type: GrantFiled: August 25, 2009Date of Patent: September 17, 2013Assignee: CareFusion 2200, Inc.Inventors: Brian Pierro, Steven M.

Patent number: 8464635Abstract: A frying system for frying a food product is disclosed having an endless conveyor system for cooking product in a bath of hot cooking oil. The endless conveyor system includes a submerging conveyor, a main conveyor, and a sediment conveyor, permanently, successively linked to one another. The endless conveyor system is also permanently linked to a hood portion of the housing. The sediment conveyor includes a heat exchanger constantly connected thereto for heating the bath of hot cooking oil. The heat exchanger includes a plurality of elongated elliptical shaped conduits and further may include a baffle that may operate as an elongated fluid flow optimization member to re-direct the flow of fluid. The hood portion of the housing of the frying system is capable of being raised and lowered from a closed, operative position to an open, inoperative position, and to intermediate positions therebetween.Type: GrantFiled: January 17, 2008Date of Patent: June 18, 2013Assignee: Alkar-RapidPak-MP Equipment, Inc.Inventors: Robert Jeffrey Sprinkle, Jason M.

Publication number: 20110253147Abstract: A breathing apparatus includes a supply tube configured to provide a supply of air. A first and second nasal interface each include a generally spherical member having a respective projection configured to be at least partially received within a respective nasal passage of a user, and are independently movable relative to the housing. A valve is disposed between the fluid chamber and an exhaust passage for selectively allowing air to be exhausted from the fluid chamber via the exhaust passage. A diaphragm, coupled to a bias chamber, is also coupled to the valve for moving the valve between the open position and the closed position. Bias pressure within the bias chamber is regulated, at least in part, by a loading fluid impedance and a venting fluid impedance.Type: ApplicationFiled: April 19, 2010Publication date: October 20, 2011Inventors: Michael H.

Publication number: 20100307011Abstract: An engine is connected to the upper end of a drive shaft housing and a work head with a string trimmer or blower or both is operatively connected to the lower end of the drive shaft housing and is rotatably driven by an engine rotating a drive shaft inside the drive shaft housing and connected to the working head. The drive shaft housing is rigidly connected to the working head and may be rotated about its longitudinal axis relative to the engine in any desired amount of rotation, but the preferred degree of rotation is 135° to move the working head from a trimming position with the rotating trimmer string in a horizontal position to an edging position with the rotating trimmer string in a vertical position and with the working head being displaced to the operator's right side for better viewing and control and operator comfort.Type: ApplicationFiled: June 21, 2010Publication date: December 9, 2010Applicant: HEOW, INC.Inventors: EDWARD P.

Patent number: 7841335Abstract: Various embodiments of a breath-activated nebulizer with flow-based fluidic control and related methods of using such a nebulizer are disclosed. The nebulizer may include a body comprising a reservoir for holding medication, a nozzle for emitting a jet of pressurized gas, and a fluid conduit in communication with the reservoir for delivery of the medication proximate the jet to produce an aerosol of medication. The nebulizer may also include a nebulizer outlet in communication with the body for delivery of the aerosol to a patient, an entrainment passage for providing entrainment flow from atmosphere during inhalation by the patient, and a control conduit in fluid communication with the fluid conduit for delivery of a control gas to the fluid conduit to prevent the delivery of the medication proximate the jet. In some exemplary embodiments, the control conduit may comprise a gas passage proximate the entrainment passage to allow the control gas to flow across the entrainment passage.Type: GrantFiled: March 29, 2007Date of Patent: November 30, 2010Assignee: CareFusion 2200, Inc.Inventors: Steven M.

Patent number: 7815396Abstract: A wave generating apparatus and method in which a chamber is at least partially submerged beneath a body of water in a pool and is connected to a gas supply for at least partially filling the chamber with gas, displacing water in the vicinity of the chamber. A vent valve is arranged to vent gas rapidly from the chamber so that the water level in the vicinity of the chamber falls, forming a wave trough. A wave reflecting wall is positioned in the pool adjacent the chamber and in the vicinity of the wave trough formation so as to reflect the wave away from the chamber and across the body of water. The chamber may have a flexible wall for displacing water or may be a rigid chamber communicating with the water through a submerged passageway. This apparatus forms a wave trough followed by a wave peak which travels across the pool.Type: GrantFiled: October 1, 2007Date of Patent: October 19, 2010Assignee: American Wave Machines, Inc.Inventors: Bruce C. McFarland, Steven M Harrington

Patent number: 7611333Abstract: Disclosed is a pneumatically powered high-pressure and lightweight fluid pump. The pump is useful for pumping fuel for liquid rocket engines and for transferring liquids from one space vehicle to another. During operation of the pump, liquid is drained from a tank into a pump chamber and the chamber is then pressurized to deliver fluid. The chamber is then refilled from the main tank. An auxiliary chamber supplies fuel while the main chamber is being filled, thereby a steady stream is delivered from the pump. The auxiliary chamber is refilled from the tank while the main chamber is delivering fluid. In order to transfer fluid from the tank to the pump chamber, the pressure in the pump chamber is maintained at a pressure higher than the vapor pressure of the fluid being pumped but lower than the pressure in the tank.Type: GrantFiled: May 27, 2005Date of Patent: November 3, 2009Inventor: Steven M. Harrington
