Abstract: A hydrogen permeation membrane that selectively allows the passage of hydrogen and that can be formed in a desired shape is obtained by using a silicon resin that includes at least phenylheptamethylcyclotetrasiloxane and/or 2, 6-cis-diphenylhexamethylcyclotetrasiloxane. A heat-resistant coating that is resistance to temperature of 300°C or higher is obtained in a sintering process at temperature of 200°C to 500°C, thereby providing a hydrogen or helium permeation membrane that has excellent water resistance. Similarly, a hydrogen or helium storage membrane that selectively stores hydrogen and that can be formed in a desired shape can be formed by using a silicon resin that includes at least phenylheptamethylcyclotetrasiloxane and/or 2, 6-cis-diphenylhexamethylcyclotetrasiloxane. A heat-resistant coating that is resistance to temperature of 300°C or higher is obtained in a sintering process at temperature of 200°C to 500°C, thereby providing a hydrogen or helium storage membrane that has excellent water resistance.

Title: Brake force transducer for electric brakes
Inventor: DALTON KEVIN M
IPC: B64C25/44
Filed: 2007-05-08
Granted: 2010-12-07
Abstract: An electric brake actuator for the brake system of an aircraft is presented. A brake actuator includes a piston driven by a cylindrical nut and screw arrangement, driven by an appropriate motor of the actuator. Application of brake force results in a reactionary force that deflects the top cover of the actuator. The axial component of this deflection correlates directly with the brake force applied. A beam is interposed between this cover and a top cap, such that deflection of the beam correlates to applied brake face. Piezo-resistive devices are connected to the beam and, through a whetstone bridge, provide an electrical output signal correlating to applied brake force.

Granted: 2014-09-30
Abstract: In a well stimulation method, a subsurface formation is fractured by freezing a water-containing zone within the formation in the vicinity of a well, thereby generating expansive pressures which expand or created cracks and fissures in the formation. The frozen zone is then allowed to thaw. This freeze-thaw process causes rock particles in existing cracks and fissures to become dislodged and reoriented therewithin, and also causes new or additional rock particles to become disposed within both existing and newly-formed cracks and fissures. The particles present in the cracks and fissures act as natural proppants to help keep the cracks and fissures open, thereby facilitating the flow of fluids from the formation into the well after the formation has thawed. Preferably, the freeze-thaw steps are carried out on a cyclic basis. Optionally, propagation of the freezing front into the formation may be enhanced by the introduction of low-frequency wave energy into the formation.

Title: Spray applied building wrap coating material, spray applied building wrap, and building construction assembly
Inventor: FAY RALPH MICHAEL
IPC: C09D5/14
Filed: 2007-06-19
Granted: 2014-10-28
Abstract: A spray applied building construction coating material forms a waterproofing, water vapor permeable, air barrier, building wrap coating layer between an exterior facing surface of a building sheathing layer and an interior facing surface of an exterior building cladding layer. A building construction assembly is formed by spray coating the exterior surface of the sheathing layer with the coating material or by spray coating gaps in the sheathing layer with the coating material and spray coating the exterior surface of the sheathing layer and previously coated gaps in the sheathing layer with a second coat of the coating material and applying an exterior cladding layer over the coating layer(s). For most applications, the coating material is formulated or includes additives whereby it solidifies on the sheathing to form a coating layer that has an exterior facing, textured surface. This exterior facing, textured surface provides passages between the exterior facing surface of the coating layer and an interior facing surface of the exterior cladding layer for draining water from between and permitting air flow between the exterior facing surface of the coating layer and the interior facing surface of the exterior cladding layer.

Abstract: A method and a device for determining a switching time of an electric switching device. An electric switching device includes an interrupter link. A first line section and a second line section can be connected and disconnected by way of the interrupter link. In order to determine a switching time, the temporal progression of a driving voltage is determined in the first line section. In addition, a temporal course of an oscillator voltage appearing in the second line section is determined.  Potential switching times are determined at the voltage zero crossings of a resulting voltage. The selection of the potential switching times ensues while evaluating the rises of the driving voltage and of the oscillator voltage or of the polarity of the oscillating current.

Abstract: A media gateway, which generates a context based on a control message transmitted from a media gateway controller and controls bearer transfers between a first network and a second network, comprises a context determination unit, an optimization judgment unit, an optimization processing unit, and a context control unit. The context determination unit determines an existence of an internal connection between a first context related to the first network and a second context related to the second network based on the respective control messages. The optimization judgment unit judges a possibility for generating a new third context by combining the first context and the second context, when the internal connection exists. The optimization processing unit generates the third context when it is possible to generate, and associates resource information of the third context with each of resource information of the first context and the second context. The context control unit controls the bearer transfer between the first network and the second network based on the third context, and performs communication with the media gateway controller using respective resource information of the first context and the second context.
