Embodiments of the present invention provide a method and apparatus for flow testing multiple zones in a single trip. In one embodiment, a method of flow testing multiple zones in a wellbore includes lowering a tool string into the wellbore. The tool string includes an inflatable packer or plug and an electric pump. The method further includes operating the pump, thereby inflating the packer or plug and isolating a first zone from one or more other zones; monitoring flow from the first zone; deflating the packer or plug; moving the tool string in the wellbore; and operating the pump, thereby inflating the packer or plug and isolating a second zone from one or more other zones; and monitoring flow from the second zone. The zones are monitored in one trip.

A method of delivering filtered water includes exerting a first pressure against a first side of a diaphragm. A second pressure is exerted, with the filtered water, against a second side of the diaphragm. The second pressure is eliminated on the second side of the diaphragm such that the filtered water flows away from the diaphragm at the first pressure exerted against the first side of the diaphragm.

A test core clamp comprising a first longitudinally split tube comprising a split portion having opposing ends and attached to a base, and a tightening device for moving the opposing ends towards each other. The tightening device comprises two brackets one affixed to each of the opposing ends and both having apertures therein. One of the bracket apertures is threaded to engage one end of a clamping bolt inserted through and rotating freely within the other bracket aperture such that rotation of the clamping bolt causes the opposing ends to close or open. According to a preferred embodiment, an insert comprising a second longitudinally split tube having a plurality of fins extending radially from its outer surface is slideably located inside of the first split tube with the fins frictionally engaging the inner surface of the first split tube such that closing and opening of the first split tube results in opening and closing of the second split tube.

A tissue product having improved hand feel and good wettability is produced by printing onto one or both sides of the tissue an aqueous emulsion containing a derivitized amino-functional polysiloxane. The derivitized amino-functional polysiloxane structure has one or more pendant groups containing an amine derivative.

A portable, preferably hand held control module for use in a heating, ventilating or cooling (HVAC) system that includes at least one subsystem that may be controlled via a service module which is located in proximity to that subsystem. The portable control module includes a plurality of manually operated keys for enabling a user to apply to the subsystem commands which are generally the same as commands which may be applied via the manually operable keys of the service module. The portable control module also includes a display assembly having one or more displays for displaying to the user information concerning the subsystem that is generally the same as that which is displayed on the display assembly of the service module. Finally the portable control module includes a coupling assembly which allows it to be detachably connected to the subsystem, or to a local area network (LEN) which services the subsystem, to enable the user to apply commands to and receive information from the subsystem without being in proximity to the service module.

A variable magnification telescopic rifle sighting means includes an externally-located zoom adjusting ring rotatable about sighting means axis and modified to provide a digitally-activated zooming feature, permitting an essentially instantaneous switching over the range of magnification settings. The switching means includes an annular recess on the periphery of the magnification adjusting ring suited to receive on end of a flexible cable. The cable length is adapted to extend and be coupled to a grippable means that can slide longitudinally upon manipulation within a slotted bracket mounted on the rifle stock. A second protective collar embraces the modified magnification ring and has an aperture for control cable translation. The movement of the grippable means through its line of travel via the cable effects a concurrent shifting of the zoom adjustment ring setting.

Embodiments of the present disclosure are also directed to a web-configuration system that includes at least one processor and one or more tangible, machine-readable media at least collectively including or storing instructions executable by the at least one processor. The instructions include a module configured to limit configuration options for a welding system based on user selection of a power source for the welding system, a module configured to calculate a weld cable size for the welding system based on the user selection of the power source and user selection of an input voltage, a module configured to assign weld cable characteristics based on the weld cable size and a user selected cable length, and a module configured to assemble a welding system order based at least on the user selection of the power source and the weld cable characteristics.
摘要:
A gas turbine engine has a turbine section and an air moving section upstream of the turbine section. A seal is between a static surface and a rotating surface in at least one of the turbine section and air moving section. The seal includes a seal shoe which is biased at least in part by a spring force, with the spring force created by cuts formed to provide a gap to allow arms associated with the seal to provide the spring force. The movement of the shoe is along a direction having at least a component parallel to an axis of rotation of the gas turbine engine. In addition, an axially moving non-contact seal is claimed.

A flexible seal system for a gas turbine engine includes an annular mounting bracket, an annular support bracket, an annular flexible seal and a plurality of mounting spacers. The flexible seal extends axially between a first mounting segment and a second mounting segment. The first mounting segment is connected axially between the mounting bracket and the support bracket, and includes a plurality of mounting apertures that extend axially through the first mounting segment. Each of the mounting spacers is arranged within a respective one of the mounting apertures, and extends axially between the mounting bracket and the support bracket.
摘要:
An apparatus and methods are disclosed for controlling load shedding and payback spikes of a population by segregating the population into subsets based on predicted energy consumption usage and peak load profiles. Subset populations respond independently from another based on a communication message sent to the population. Each subset population of homes with one or more energy consuming devices responds based on a generated value generated from a randomizing distribution routine.
