Patent number: 7294174Abstract: An air dehydration membrane is made of a hydrophilic polymer having a permeability for water vapor which is greater than its permeability for air, and having low selectivity between oxygen and nitrogen. The membrane has a hydrophilic coating, which itself may be a polymer. The coating does not affect the selectivity of the coated membrane with respect to oxygen and nitrogen, but does increase selectivity of the membrane with respect to water vapor. A preferred material for the membrane is polysulfone. Preferred materials for the coating are poly vinyl alcohol and Triton X-100. The membrane is selected such that the dominant mechanism for gas flow through the membrane is Knudsen flow. The membranes are made at low cost, and can outperform existing commercial membranes in either volumetric productivity or product recovery.Type: GrantFiled: July 20, 2005Date of Patent: November 13, 2007Assignee: Generon IGS, Inc.Inventors: Frederick L.

Patent number: 7278495Abstract: A horseshoe includes a thin, resilient member, embedded in a moldable material such as plastic or composite. Due to this dual construction, the horseshoe is strong yet light in weight. The moldable material has a thickness which varies across the horseshoe, so as to define a cavity in the space between the shoe and the horse's hoof. A channel, formed in the moldable material, provides access to the cavity, which can be filled with a medicated material after the shoe has been attached to the hoof. In an alternative embodiment, a source of current can be connected across the ends of the resilient member, causing the resilient member to function as a resistance heater, which can melt an adhesive used to attach the shoe to the hoof. The latter alternative can also be practiced with conventional all-metal horseshoes, or with an insulating horseshoe that is provided with an external conductive element.Type: GrantFiled: March 21, 2005Date of Patent: October 9, 2007Inventor: Robert A. Kolonia, Sr.

Patent number: 7278607Abstract: A solar-powered aircraft uses solar energy to electrolyze on-board water to produce hydrogen. The hydrogen fills various on-board tanks, causing the aircraft to become lighter than air. The hydrogen is also used to operate a fuel cell which provides power for electrical equipment, including a motor for turning a propeller. Water produced as waste by the fuel cell is recycled for use in the production of hydrogen. When hydrogen is removed from the tanks, either because it is consumed by the fuel cell or because it is compressed and pumped out of the tanks, air returns to the tanks, and the aircraft becomes heavier than air. The aircraft can thus be made to climb and descend by making it lighter than air, or heavier than air. The aircraft emits no harmful substances into the environment. The aircraft can remain aloft indefinitely, limited only by an insignificant amount of leakage of hydrogen and water.Type: GrantFiled: August 12, 2005Date of Patent: October 9, 2007Inventor: Howard J. Fuller

Patent number: 7230233Abstract: A programmed computer analyzes data from a mass spectrometer. A spectrum corresponding to an unknown sample is perturbed in various ways, and each perturbed spectrum is compared with the spectrum of a known or reference substance. The perturbed spectrum having the highest correlation with the known spectrum, and which is also physically plausible, is considered to be the best fit. The method indicates in what specific ways the unknown sample differs from, or is similar to, the known substance.Type: GrantFiled: March 21, 2006Date of Patent: June 12, 2007Assignee: Novatia, LLCInventors: Jeffrey L.

Patent number: 7198005Abstract: A pet feeder includes a base and a lid, the base defining a bowl and the lid defining a reservoir. The base and lid are connected by a hinge, such that the lid can be retained in an open position. Solid food or liquid flows from the reservoir, through a valve, into the bowl. In the case of liquid, the supply of liquid in the bowl is continuously replenished due to the flow of liquid, by gravity, into the bowl. In another embodiment, the feeder may include a single base and separate bowls and separate lids, so that the feeder may provide both solid food and liquid simultaneously. When the lid is closed, the pet feeder becomes a compact structure that can be easily stored and transported.Type: GrantFiled: July 5, 2006Date of Patent: April 3, 2007Inventor: Ralph F.

Patent number: 7179313Abstract: A compact steam reformer produces hydrogen to power a fuel cell, such as can be used in a vehicle. The steam reformer includes a first channel, at least partly coated with a steam reforming catalyst, and a second channel, at least partly coated with a combustion catalyst, the channels being in thermal contact with each other. Heat from the combustion is used in the steam reforming reaction. In another embodiment, the gas streams feeding the reforming and combustion channels pass through a valve which reverses the gas streams periodically. The combustion channel becomes the reforming channel, and vice versa, so that carbon deposits in the former reforming channel are burned off. This arrangement enables the reforming reaction to continue indefinitely at peak efficiency.Type: GrantFiled: January 17, 2003Date of Patent: February 20, 2007Assignee: Catacel Corp.Inventors: William B. Retallick, William A. Whittenberger

Patent number: 7150099Abstract: A heat exchanger is formed of a strip of corrugated material that is folded back and forth upon itself to define a stack. Cut pieces of corrugated material are inserted within the folds of the strip, such that the corrugations of the cut pieces are generally perpendicular to the corrugations of the folded strip. A set of duct attachments holds the assembly together, and provides paths for fluid flowing into and out of the exchanger. The ends of the stack, and those parts of the sides that are not spanned by the duct attachments, are sealed with a high-temperature sealant. The sealant is preferably a moldable material that is applied and allowed to harden, and which has a coefficient of thermal expansion that approximates that of the stack. The heat exchanger is easy and inexpensive to manufacture, but is suitable for use in high-temperature applications.Type: GrantFiled: March 30, 2004Date of Patent: December 19, 2006Assignee: Catacel Corp.Inventors: William A.

Patent number: 7104212Abstract: A wireless remote control system enables precise control of a yacht, or other vessel, from virtually any point on the yacht. A hand-held transmitter includes various switches for controlling the engines, thrusters, and/or anchor winch. A receiver, mounted on the yacht, receives signals from the transmitter. The receiver generates outputs that are connected to the existing electronic controls of the yacht. Thus, the receiver is connected in parallel with the conventional electronic controls of the yacht, and the system acts in addition to, and not instead of, the conventional control system. The system can thus be installed on existing vessels without modification of such vessels. An acoustic alarm signal is generated by the receiver when radio communication between the transmitter and receiver is severed.Type: GrantFiled: August 11, 2004Date of Patent: September 12, 2006Inventor: Giuseppe Brianza

Patent number: 7077999Abstract: A monolith for imparting swirl to a gas stream includes a stack of alternating flat and corrugated strips defining channels for gas flow. The strips are attached, at an angle, to a carrier. Also, the corrugations of the corrugated strips may be skewed. The carrier defines a cylindrical shell for the strips, and the strips extend from the carrier to a central region. The strips are curved, typically having substantially the shape of involutes, and substantially fill the space between the central region and the shell. Due to the angle of attachment between the strips and the carrier, the gas flow channels are oriented in different directions, at different locations on the outlet face of the monolith. This structure therefore imparts swirl to gas flowing through the monolith.Type: GrantFiled: May 23, 2002Date of Patent: July 18, 2006Assignee: Catacel Corp.Inventor: William A. Whittenberger
