20120073828 | DOWNHOLE MATERIAL DELIVERY - A method of delivering material, typically lost circulation material (LCM), into a hole via a tubular string comprises: opening a bypass port in a tubular string located in a drilled hole, the bypass port being provided above fluid outlets in the distal end of the string; delivering material through the string from surface, the material passing through the bypass port and into the drilled hole; and locking a volume of fluid in the string between the bypass port and the fluid outlets such that fluid is prevented from passing from the hole into the string via the fluid outlets. | 2012-03-29 |
20120073829 | Fail Safe Regulator for Deep-Set Safety Valve Having Dual Control Lines - A hydraulic control system for a sub-surface safety valve has control lines in hydraulic communication with the valve. A first control line communicates hydraulic pressure to actuate the valve, while the other control line communicates hydraulic pressure to compensate for hydrostatic pressure associated with the first control line. A regulator regulates hydraulic communication between the two control lines. The regulator prevents fluid communication from the first to the balance control line as long as integrity of the second line is maintained. When the second line fails, the safety valve can fail in the open position. In this case, the regulator permits hydraulic pressure to bleed from the first line to the second line. This allows the safety valve to then fail in a closed condition and allows the second line to potentially be recharged if its integrity is regained. | 2012-03-29 |

20120073884 | SINE WAVE SPRING - A spring is formed of a relatively thin sheet of spring material which is constricted and held in place at each end forming a bell curve being located between two substantially planar members. As additional compressive force is applied in the vertical direction, the curve then compresses and starts to form sine waves. The greater the force, progressively higher the wave frequency with lower amplitude would form. When the force is removed, the flexible material returns to its original shape. The force needed to shift the curve (increase the number of waveform) increases at an exponential rate, as opposed to the linear rate of most normal springs. The maintenance force of new stable state is considerable less than the threshold force. Such a relatively flat spring with an exponential spring rate and self dampening through phase change has a number of useful applications for automotive and industrial use. | 2012-03-29 |
