Abstract: Methods and apparatus for communicating between surface equipment and downhole equipment. One embodiment of the invention provides a wellhead assembly that allows electrical power and signals to pass into and out of the well during drilling operations, without removing the valve structure above the wellhead. Another embodiment of the invention provides an electromagnetic casing antenna system for two-way communication with downhole tools. Another embodiment of the invention provides an antenna module for a resistivity sub that effectively controls and seals the primary/secondary interface gap.

Abstract: The present invention generally provides methods and apparatus for reducing noise in a detected electromagnetic wave used to telemeter data during a wellbore operation. In one embodiment, two surface antennae are placed on opposite sides of the wellbore and at the same distance from the wellbore. The signals from the two antennae are summed to reduce the noise in the electromagnetic signal transmitted from the electromagnetic downhole tool.

Abstract: A thin profile wipe dispensing container is provided for dispensing wipes from the edge of a stack of wipes. The dispensing container has a contoured shape to minimize shelf space and integrate with any space and includes an angled container body and hinged lid that snaps shut. The lid is flush with the container body when closed providing the thin profile wipe dispensing container that may easily and economically be used, stored and transported. The container body may further include a removable bridge in an open mouth of the container body with a dispensing aperture through which the wipe may be drawn. The container body may also include a spring device for maintaining the position of the wipes within the dispensing container to help dispense one wipe at a time.

Abstract: A multi-chamber wipe container holds at least two supplies of wipes. The wipe supplies are disposed within a receptacle that may be a housing (which housing may or may not be divided by a rib) or may be a plurality of canisters. The wipes are dispensed through a lid assembly, which preferably has an opening corresponding to each wipe supply.

Abstract: A needlepunched nonwoven wipe containing a flowable product, activated by the addition of water, permits sustained release of the product.

Abstract: A surface treatment article is provided that includes wet layer(s) of at least one lower substrate layer and at least one flexible container containing a product and having at least one rupturable barrier adapted to burst under an application of pressure to allow at least a portion of said product to be expelled from the at least one flexible container onto a target surface. The surface treatment article may also include at least one substantially moisture impermeable layer over the wet layer(s) to act as a barrier between the user and the wet layers (product). The bottom surface of the at least one lower substrate layer may be covered by an apertured thermoplastic film to substantially ensure one-way flow of the product and stain removed from the target surface.

Abstract: Isotropic magnetic alloy powder having an intrinsic magnetic induction of at least two third of its magnetic remanence and method for making same are provided. The powder is made from an alloy having a composition comprising, by weight percentage, approximately 15 to 35 percent of one or more rare earth metals, approximately 0.5 to 4.5 percent of boron, and approximately 0 to 20 percent of cobalt, balanced with iron. The alloy powder is made by a process wherein an amount of the alloy is melt and spun in an inert environment, preferably at a distance between an orifice and a wheel being less than one and one half inches, into ribbons, followed by crushing the ribbons into powder and annealing the powder.

Abstract: An exercising apparatus. The exercise apparatus includes an outer frame having curved first and second rails and an outer handle between the rails, and an inner frame slidably coupled to the outer frame for movement of the inner frame along the first and second rails. The inner frame includes an inner handle movable toward the outer handle when the inner frame is moved in a first direction. The apparatus also includes at least one resistance device coupling the inner and outer frames together, the resistance device resisting movement of the inner frame in the first direction.

Abstract: An electronic display generates an image which, through substantial registry of two opponent vector images, is perceived as a full color image. The display receives two channels of information representing two opponent color vectors of an image to be displayed, develops two images in the two opponent color vectors, and superimposes the two images to generate the image which is perceived as a full color image.

Abstract: A humidity controller includes a set point device, which establishes a set point for humidity within a given area, and a humidity sensor, which senses the humidity within the area, connected in a sensing network which provides a differential output voltage indicating deviations of the humidity from the set point. The output voltage selectively enables differential threshold detecting circuits which energize humidifying and dehumidifying apparatus to return the humidity to the set point value. A differential range adjust, which establishes a turnon threshold for the detecting circuits, is derived from the set point such that the turnon differential for the detecting circuits remains fixed regardless of the set point value.
