The present invention provides a recess within an expandable downhole tubular, such as an expandable sand screen. The recess resides within the wall, such as the outer shroud of an expandable sand screen. The recess serves as a housing for instrumentation lines, fiber optics, control lines, or downhole instrumentation. By placing the lines and instrumentation within a wall of the expandable downhole tool, the tool can be expanded into the wall of the wellbore without leaving a channel outside of...

A tube made of profiled strip has an inner edge, an outer edge parallel to the inner edge and projecting away from the inner edge, a double-thickness outwardly directed inner lip forming between the edges an outwardly open inner slot, and a double-thickness inwardly directed outer lip forming between the inner slot and the outer edge an inwardly open outer slot. The strip is formed into turns centered on an axis with the inner slot of each turn axially slidably receiving the outer lip of the adj...

A disposable plate or tray includes a substantially planar bottom portion, a sidewall and a flange. A profile extending from the center to the outer edge of the article is characterized by a plurality of direction changes having a radius of curvature to diameter ratio of at least about 0.02.

A treatment jet or beam, e.g. from a high velocity oxygen-liquid fuel (HVOF) spray gun, has an axis intersecting the surface of a rotor at a given point. The rotor has a profile which progresses helically along it. The point is traversed along the rotor while keeping the point at the same position on the rotor profile. In particular the jet axis is moved parallel to the rotor axis while the rotor is rotated in synchronism.

A method of forming a container body having a profiled bottom in a continuous operation wherein the body is formed from a blank of material into an inverted cup, the cup is reverse drawn and a preliminary profile is imparted to the bottom of the cup, and a final profile is imparted. The apparatus includes a die cut edge movable into telescoping relationship around a redraw die to form the inverted cup and a profile punch movable into telescoping relationship within the redraw die to form the pre...

The invention provides an axial flow blood pump with slanting outflow components. Specifically, the invention provides a blood pump having an angling outer stator blade edge structure in combination with a blood flow conduit having a constricting inner diameter. After constricting, the blood flow conduit can expand such that the inner diameter of the conduit increases. In addition, the blood pump can have an angling inner stator blade edge structure and a tapering stator blade hub or tapering ro...

A wire has a conductor and an insulation extruded onto the conductor. The insulation has a plurality of alternating crests and crevasses, where the ratio of the distance from the conductor to a top of the crest to the distance from the conductor to a lowest point in the adjacent crevasse is at least 1.1 and where the ratio is sustained within a tolerance variation of not more than 15% along the length of the wire.

A slider device and methods of making. The slider device is for use with a resealable package having a zipper closure, and includes a top wall with first and second ends, a spreader depending from the top wall, a first sidewall with a first hook construction extending therefrom, and a second side wall with a second hook construction extending therefrom. An extended length of profiled material is extruded and can be converted to form individual slider devices. The spreader can be tapered, either ...
