Title: Iontophoretic drug delivery system, including disposable patch
Inventor: FLOWER RONALD J
IPC: A61B19/00
Filed: 1996-09-27
Abstract: An iontophoretic drug delivery system of the present invention includes a disposable patch (10) electrically interconnectible with a controller (12). The patch includes at least two electrode assemblies, with one of the electrode assemblies having a first electrode (16) and a second electrode (18). In this way, during delivery of electrical current one of the electrodes is exhausted so that upon an attempt to reuse the patch, the controller (12) does not detect the delivery of electrical current through said electrodes and fails to supply electrical current to the electrode assemblies for delivery of the drug. Electrical interconnection between the patch and the controller is established by inserting a tab extending from the patch into the controller.

Title: Compositions and methods for hydraulic fracturing
Inventor: LE HOANG V
IPC: C09K8/64
Filed: 1998-06-03
Abstract: A subterranean formation is treated by introducing a fracturing treatment composition comprising a polymer treatment fluid containing a dispersion of hydrophilic water swellable particles into the formation. The water swellable particles comprise synthetic polymers that are crosslinked so that they are water insoluble, but capable of swelling in the presence of relatively small amounts of water. When used with treatment fluids containing at least a small amount of water, the particles swell and reduce fluid loss to the formation during the treatment. When used during a hydraulic fracturing treatment of a hydrocarbon bearing formation, the particles may also reduce or eliminate water production following the fracturing treatment by restricting the extension of a fracture into water-bearing formations, and/or by restricting the flow of fluids from water-bearing areas.

Patent CA-2251393-A1 (CA)
Inventor: KLOPP GERHARD O
IPC: F01N3/28
Filed: 1998-10-23
Abstract: A compact reversing flow catalytic converter for reducing noxious substances in exhaust gases produced by internal combustion engines is described. The catalytic converter includes a valve unit which reversibly directs exhaust gases through a container filled with catalytic material. The container defines a U-shaped gas passage which communicates with two ports at a top of the container. The valve unit is mounted to the top of the container and includes an intake and an exhaust cavity. The valve unit includes a valve disk having two openings therethrough and rotates around a perpendicular central axis between a first and second position. In each position, each opening communicates only with one of the cavities and one of the ports. In the first position, the exhaust gases enter the exhaust cavity from an exhaust pipe and pass through one of the openings into the gas passage where they contact the catalytic material as they travel through the U-shaped gas passage and enter the exhaust cavity. In the second position, the two openings are rotated 90° so that each opening communicates with the same cavity but a different one of the ports. Therefore, the gas flow through the U-shaped gas passage is reversed. The advantage is a compact, reliable, highly-efficient catalytic converter that is inexpensive to manufacture.

Title: Modified acrylic urethane prepolymer concentrate and polyester resins containing same
Inventor: SMITH STUART B
IPC: C08G18/68
Filed: 1997-04-10
Abstract: A modified acrylic urethane prepolymer composition and an unsaturated polyester resin composition to which the prepolymer has been added. The prepolymer composition includes an acrylic urethane prepolymer prepared by the reaction of diisocyanate, like MDI, with a hydroxyl-containing acrylate monomer, such as a pentaerythritol triacrylate, which prepolymer composition may contain a styrene monomer and an inhibitor, such as benzoquinone, to retard the reaction of the prepolymer and styrene monomer prior to the addition of the prepolymer composition into the polyester resin composition.  The employment of the modified urethane prepolymer composition provides for the reduction in the amount of styrene monomer used in the unsaturated resin composition and also provides for improved chemical and physical properties of the cured, unsaturated resin composition, such as a reduction in glass roll-out when the resin composition is employed with fiberglass.

Title: Expiratory flow rate calculator
Inventor: BURKE JOHN
IPC: A61B5/087
Filed: 1992-10-02
Abstract: The present invention is a method for determining human expiratory flow rate, comprising a peak flow meter and a zone calculator. The peak flow meter is used to determine what the user's peak expiratory flow rate is in conjunction with medical data compiled on the zone calculator. The individual's peak expiratory flow rate and predetermined sub-optimal values are applied to the peak flow meter as color zone settings. The peak flow meter thus set is ready for the individual to use to determine whether he is functioning in the peak expiratory flow rate color zone, or one of the sub-optimal expiratory flow rate color zones. The color zones correspond to specific remedial measures to be followed by the individual in case of sub-optimal expiratory flow rate.

Title: Automatic power turn-on circuit for a battery-powered voltage measurement apparatus
Inventor: GALLAVAN MICHAEL
IPC: G01R15/12
Filed: 1999-01-20
Abstract: An automatic power turn-on circuit for a battery-powered measurement instrument. Instrument power is normally off, and when the instrument is connected to a voltage to be measured, the voltage that is sensed activates an electronic switch that in turn connects an internal battery to the processing and display circuits of the instrument. The voltage sense circuitry includes circuits for sensing either a positive or a negative voltage, and biasing a driver transistor into conduction. The driver transistor in turn activates the switch to connect the battery voltage to a power supply output node. An RC  network holds the switch in the "on" position for a short period of time after the voltage to be measured is removed from the inputs of the instrument.
