Abstract: A printed circuit board employing a heat sink retaining apparatus and method of use is disclosed. In one form of the disclosure, a heat sink apparatus can include a heat sink operable to be coupled to a first portion of a printed circuit board having an integrated circuit, and a retaining mechanism operably coupled along a first surface of the heat sink. The retaining mechanism can be coupled to a second portion of the printed circuit board to produce a tension between the first surface of the heat sink and the second portion of the printed circuit board.

Abstract: An interface retention and support apparatus and method of use is disclosed. In one form, an extension apparatus can include a first coupling interface operable to be coupled to an first expansion terminal of a printed circuit board. The apparatus can also include a retention mechanism aligned to a surface of the first coupling interface. The retention mechanism can be used to engage a first exterior surface of the first expansion terminal upon coupling the first coupling interface to the first expansion terminal. The apparatus can further include an access terminal operably coupled to the first coupling interface and an expansion circuit coupled between the first coupling interface and the access terminal. The expansion circuit can electrically couple the first expansion terminal to access terminal.

Abstract: An information handling system cooling system operates according to a thermal profile selected by a thermal profile manager based upon venting detected as available through a chassis wall. Venting through the chassis is provided, in part, by vent openings formed in a blank coupled to the chassis. A first thermal profile is selected if the blank is detected coupled to the chassis. A second thermal profile is selected if the blank is replaced with a component. The thermal profile is selected based upon detection of the component by the information handling system or, alternatively, by detection of the blank coupled to the chassis.

Abstract: A tubular body made of a first metal and having a box end and a connection end, the box end having an internally threaded portion and an internal cylindrical thread-free portion axially outward of the threaded portion, the tool joint further including an anti-fretting section, preferably in the form of a sleeve of a second metal that is snugly received in a counterbore formed in the box end, the sleeve having an internal cylindrical surface having a diameter substantially the same as the internal diameter of the cylindrical thread-free portion of the box end, the second metal having a modulus of elasticity less than the modulus of elasticity of the first metal, the invention further including a drill pipe made by affixing first and second tool joints as described above to first and second opposed ends, respectively, of an elongate pipe body, the pipe body being affixed to the tool joints by a threaded shrink-grip connection, the first tool joint forming a box connection, the second tool joint forming a pin co

Abstract: A drill pipe 10 comprises an elongate pipe section 12 having a substantially uniform pipe outer diameter 18 and a substantially uniform pipe inner diameter 20. A pin tool joint 14 is welded at one end to the pipe section, and a box tool joint 16 is welded to the other end of the pipe section. Each of the pin and box tool joints includes a thread for mating engagement and preferably first and second shoulders. The drill pipe has a ratio, R, which takes into consideration the pipe inner diameter, PID, the pipe outer diameter, POD, the tool joint inner diameter, TJID, and the tool joint outer diameter, TJOD. This ratio may be expressed as: R = ( P ID + TJ ID ) ( TJ OD - P OD ) .

Abstract: An intermediate weight member (10) having a variable cross-section or bending moment of inertia as a function of member length is disclosed. At one end of the member (10) a slip and elevator section (14) is provided. A partially grooved section (16) of a diameter greater than that of the slip and elevator section extends between the slip and elevator section (24) and the other end of the member (10). The partially grooved section (16) includes two variable depth grooved sections (18, 20) separated by an ungrooved section (22). The ungrooved section (22) includes hardbanding rings (26, 28). The spiral grooves (30A, 30B, 30C) of variable depth grooved section (18, 20) vary in depth as a function of member length such that the bending moment of inertia varies as a function of length from the slip and elevator section (14) to the lower end of the member (10).

Abstract: In accordance with the present invention, the drilling head includes a body or spool having a flow bore and a removable side outlet. Upon removal of the side outlet, the drilling head will pass through most rotary tables. The drilling head further includes a closure member for closing the annulus between that portion of the drilling head above the side outlet and a drive tube, such as a kelly, extending through the drilling head flow bore. The closure member includes a nonrotating support tube and a rotating seal tube adapted to form a nonrotating seal with the drive tube. The seal tube is rotatably supported by bearings within the support tube. The closure member is small enough to pass through even rotary tables that are too small to pass the drilling head.A segmented clamp secures the closure member to the drilling head body around one end of the flow bore. The clamp includes at least two segments, for fast actuation, having one end connected to a variable length linkage.

Abstract: A drill pipe 10 comprises an elongate pipe section 12 having a substantially uniform pipe outer diameter 18 and a substantially uniform pipe inner diameter 20. A pin tool joint 14 is welded at one end to the pipe section, and a box tool joint 16 is welded to the other end of the pipe section. Each of the pin and box tool joints includes a thread for mating engagement and preferably first and second shoulders. The drill pipe has a ratio, R, which takes into consideration the pipe inner diameter, PID, the pipe outer diameter, POD, the tool joint inner diameter, TJID, and the tool joint outer diameter, TJOD. This ratio may be expressed as: R = ( P ID + TJ ID ) ( TJ OD - P OD ) . According to the present invention, this ratio is greater than 8.0, and is preferably from 8.1 to 8.5, thereby providing a drill pipe with desired strength and fluid flow capabilities.
