Abstract: A method includes assembling a telescoping substructure box having first and second substructure boxes in a collapsed configuration by nesting at least a portion of the first substructure box inside of a substantially open interior space defined by a plurality of structural elements that comprise the second substructure box. The assembled telescoping substructure box is transported to a drilling site and telescopically raised from the collapsed transportation configuration to a raised operating configuration for performing drilling operations on a wellbore location of the drilling site by telescopically raising one of the first and second substructure boxes relative to the other one of the first and second substructure boxes. A drilling mast is coupled to and raised above the telescoping substructure box, and drilling operations are performed on the wellbore location with the raised drilling mast.

Abstract: A collapsible drilling rig substructure is transported to a drilling site while in a collapsed transportation configuration wherein a raisable floor of the substructure is in a lowered transportation position relative to a fixed drill floor such that an upper surface of the raisable floor is positioned at a first height level above a base of the substructure while an upper surface of the fixed drill floor is positioned at a second height level above the base that is greater than the first height level. The substructure is positioned adjacent to a wellbore location at the drilling site and reconfigured from the lowered transportation configuration to a raised operating configuration by raising the raisable floor to an operating position laterally adjacent to the fixed drill floor while maintaining a height level of the upper surface of the fixed drill floor at the second height level.

Abstract: Disclosed herein is a telescoping substructure of a drilling rig that includes first and second telescoping substructure boxes. The first and second telescoping substructure boxes each include, among other things, a lower substructure box and an upper substructure box that is adapted to be telescopically raised and lowered relative to the lower substructure box. Furthermore, each telescoping substructure box also includes raising means for telescopically raising and lowering the upper substructure box relative to the lower substructure box between a collapsed configuration for transportation and a raised configuration for drilling operations, wherein each of the first and second telescoping substructure boxes are adapted to facilitate movement of the telescoping substructure in at least one of a lateral direction and a longitudinal direction over wellhead equipment positioned above a wellbore location when the upper substructure boxes are in the raised configuration.

Abstract: Generally, the present disclosure is directed to a collapsible substructure of a mobile drilling rig. In one illustrative embodiment, a drilling rig substructure is disclosed that includes a base having a fixed drill floor mounted thereon, wherein an upper surface of the fixed drill floor is positioned at an operating height above the base for performing drilling operations at a wellbore location of a drilling site. Furthermore, a raisable floor is also included that is adapted to be positioned in a lowered transportation position for transportation of the substructure to the drilling site and raised to an operating position adjacent to the fixed drill floor for performing drilling operations, wherein a height level of an upper surface of the raisable floor is lower than a height level of the upper surface of the fixed drill floor when the raisable floor is positioned in the lowered transportation position.

Abstract: A system is disclosed that includes a drilling rig having a substructure, the drilling rig being adapted to be positioned above a plurality of wellbore location such that each of the plurality of wellbore locations is simultaneously positioned below the substructure, equipment movement means for moving pressure control equipment between positions proximate each of the plurality of wellbore locations, the equipment movement means being adapted to move the pressure control equipment between the positions while the drilling rig is performing a rig operation on at least a first one of the plurality of wellbore locations, and equipment positioning means for positioning pressure control equipment on one or more of the plurality of wellbore locations, the equipment positioning means being adapted to position the pressure control equipment on a second one of the plurality of wellbore locations while the rig operation is being performed on the first wellbore location.

Abstract: A device for increasing the range of motion of a patient's knee joint generally includes a frame, a lever member pivotally coupled to the frame at a first location, and an actuator pivotally coupled to the frame at a second location. The frame supports the patient in a manner that allows motion of the patient's knee joint, and the lever member bears against a portion of the patient's body below the knee joint. The actuator is also pivotally coupled to the lever member. When operated by a controller, the actuator generates a translational input that rotates the lever member relative to the frame and thereby stretches the patient's knee joint in a desired direction.

Abstract: Methods are provided for forming a semiconductor device from a substrate comprising a bottom gate layer, a channel layer overlying the bottom gate layer, and a top gate structure formed over the channel layer. First, a hardmask comprising a first material interposed between a second material and a third material is deposited over a portion of the top gate structure. Then, the hardmask and top gate structure are encapsulated with an insulating material to form a spacer. A channel structure is formed from the channel layer, and the channel structure is disposed under the spacer. A bottom gate structure is formed from the bottom gate layer, and the bottom gate structure is disposed under the channel structure. Then, a source/drain contact is formed around the bottom gate structure.

Abstract: An apparatus for detachably mounting a device to a rail. The rail has generally oppositely facing first and second edges, each having adjacent front and back faces. The apparatus includes a bracket on the device. The bracket has a recess for receiving the first edge of the rail. The recess includes a lip for engaging the back face of the rail adjacent the first edge. The apparatus also includes a clamp on the device. The clamp has a resilient wing for resiliently engaging the front face of the rail, proximal to the engagement between the rail and the lip. The apparatus further includes a latch for engaging the back face of the rail adjacent the second edge against the bias of the clamp.

Abstract: Packaging for microwavable convenience foods, such as tamales, and a related method for microwave steam heating or cooking of such foods. The food packaging includes an unvented, sealed, stretchable plastic bag enclosing a food product and a moisture pad which is placed on top of the food product. The pad serves to shield the food product from direct microwave radiation, and to provide a source of steam generated by absorption of the waves in the water of the pad.
