Abstract: A leg massage apparatus is provided which enables the user to easily and comfortable engage the various muscles of the leg, providing the leg muscles with a therapeutic message which helps to loosen and relieve sore or damages muscles. The apparatus may also be used to assist in the removal of cellulite from areas of the leg. The apparatus is basically comprised of a name structure means, a user engagement means, a coupling means, and an optional resistance means. The frame structure means has at least two main support members coupled together in such a manner that the leg of the user may be placed within, with the main support members surrounding a significant portion of the leg. The main support members are adjustably coupled together by the coupling means such that they may alternatively move away and towards one another, as the various leg muscles of the user are being engaged by the user engagement means. The optional resistance means may be used to provide motion resistance.

Abstract: Methods relate to tubulars that may be part of a tubular string for isolating one or more zones within a wellbore. In one embodiment, the tubular string includes a first expandable zone isolation unit disposed on a first side of a zone to be isolated, a second expandable zone isolation unit disposed on a second side of the zone to be isolated, and a perforated tubular disposed in fluid communication with a producing zone. The tubular string may be expanded using an expansion assembly having a first expander for expanding the first and second expandable zone isolation units and a second expander for expanding the at least one perforated tubular. Tags or markers along the tubular string may indicate locations where expansion is desired such that connections or connectors between joints are not expanded.

Abstract: An expansion member for a rotary expansion tool comprises a spindle adapted to be supported at both ends, and a roller mounted concentrically on the spindle. A sealed lubrication system is contained within the spindle for supplying lubricant to a bearing or bearing surface at an interface between the spindle and the roller.

Abstract: The present invention generally relates to apparatus and methods for expanding a tubular. In one embodiment, an expander tool includes a body having at least one recess therein. An expansion assembly disposable in the at least one recess includes a piston that outwardly extends from the body in response to a radially outward force. The expansion assembly includes one or more rollers disposed on a shaft such that the rollers rotate at different speeds. In order to improve a rolling ratio, the shaft is arranged on the piston at an outward angle relative to a longitudinal axis of the tool. The expansion assembly is disposed along the tool at a skew to provide tractoring and reduce slippage due to axial movement. A bearing adjacent the roller and rotationally secured to the roller reduces roller heating and wear. In another aspect, methods for expanding a tubular within a wellbore are provided.

Abstract: A turnable exercise apparatus is provided which enables the user to exercise both upper and lower body muscle groups. The apparatus includes a frame structure means, an upper body engagement means, and a lower body engagement means. The upper and lower body engagement means are coupled to the frame structure means. The user operates the apparatus while in a generally lying position. The user may push and pull backward and forward upon two handle members with their hands, which are part of the hand engagement means. This motion is transferred into a pivoting motion of the lower body engagement means, which is engaged by the legs of the user. Alternately, the user may pivot the lower body engagement means with their legs, and move said handle members of said upper body engagement means in the foward and backward directions. The lower body engagement means is pivotally coupled to the frame structure means such that the lower body engagement means may be pivoted in the forward, backward, and side directions.

Abstract: A reciprocating exercise apparatus is provided which enables the user to exercise lower body muscle groups. The apparatus includes a frame structure means, a user support means having a seat, and a user engagement means. The back end of the user engagement means is pivotally mounted to the frame structure means. An engagement assembly is mounted to the front end of the user engagement means via an assembly support, with the assembly support capable of moving in the upward and downward directions. The lower end of the assembly support is connected by a wheel member to a guide member, which is mounted on the frame structure means. To normally operate the device, the user sits in the seat and pushes against the engagement assembly, with the general thigh portion of the leg, in either the downward, upward, and/or side directions. The wheel member will follow the contour of the guide member. Optional items may include a back support member, handle members, a resistance means, and/or a motor means.

Abstract: The present invention provides methods and apparatus for expanding a first, smaller diameter tubular into frictional contact with a second, larger diameter tubular or wellbore. In an embodiment, annular formations formed on an inner surface of a split ring engage an outer surface of the smaller tubular. In one aspect, the smaller diameter tubular is provided with an annular recess there around, the annular recess including recessed grooves formed there around. Therefore, the split ring is disposable within the annular recess and the annular formations formed on the split ring are constructed and arranged to fit within the recessed grooves of the annular recess of the tubular. An outer surface of the split ring is provided with teeth or some other grip-enhancing material or formation. The split ring also includes a split portion permitting the ring to expand in diameter as that portion of the tubular is expanded in diameter.

Abstract: A water vaporization apparatus is provided which uses the heat from the sun to vaporize water from a water collection means. The water collection means has a water container member which may be partially submerged in a water reservoir, or connected to a remote reservoir of water. The water container member has a water transport member connected to it, through which water from the water reservoir may move into the water container member. The water from the reservoir will move into the water container member as the sun vaporizes water from the water container member, since the water levels will naturally try and reach equilibrium. An electricity generation means may be operatively connected to the water collection means in such a manner that the movement of the water through said water transport member may be used to generate electricity.

Abstract: A diagramming tool is provided that allows a diagram to be defined as a specialization of a “parent” diagram. The “child” diagram is defined based on the “parent” diagram such that the child diagram references the parent and contains only nodes and edges which represent differences between the instant diagram and its parent diagram. A diagram inherits all of the nodes and edges, and their properties, of its parent and adds, deletes, or redefines the nodes and/or edges that represent the differences or specializations.

Abstract: A material relocation apparatus is provided which enables an operator to load, transport, and unload material, while the apparatus may be moving in the forward and backward directions. The apparatus includes a frame structure means, a material handling means, and a power transfer means, with the material handling means and the power transfer means being mounted on the frame structure means. The material relocation means is a conventional type of load bucket, commonly found on construction equipment. It is pivotally mounted to the rear of the frame structure means, and is capable of pivoting in both the forward and backward directions via the power transfer means. An optional item may include an attachment component for attaching the apparatus to a piece of construction equipment or farm equipment, such as a tractor. The apparatus may also be part of a motorized vehicle, in which case the attachment component is not required.
