| 20090032822 | HIGH POWER LIGHT EMITTING DIODE - A high power light emitting diode, The high power light emitting diode comprises a light emitting diode chip, a main module, two first electrode pins, two second electrode pins, and at least one heat dissipation board. The main module has a concave and the light emitting diode chip is positioned in the concave. The first electrode pins are connected to a first side of the main module and also electrically connected to the light emitting diode chip. The second electrode pins are arranged on a second side of the main module that is relative to the first electrode pins wherein the second electrode pins and the first electrode pins are electrically opposite. The second electrode pins are electrically connected to the light emitting diode chip. The heat dissipation board is connected to a part of the main module between the first electrode pin and the second electrode pin. | 02-05-2009 |

| 20090120648 | CASING HEAD SLIP LOCK CONNECTION FOR HIGH TEMPERATURE SERVICE - A wellhead connection for connecting and sealing to a casing, including an upper head housing accommodating the upper end of the casing in its central bore, a stop shoulder in the central bore to allow the upper head housing to rest on the upper end of the casing, and a seal profile section formed at the lower end of the central bore below the stop shoulder. The wellhead connection is configured such that, first connecting the slip housing and bottom ring with a bottom connector energizes slip connectors into gripping engagement with the casing and locks the slip housing and bottom ring around the casing, while thereafter connecting the upper head housing and the bottom ring with a top connector energizes the metal seal ring so as to radially compress the metal seal ring against the casing to form a metal seal. | 05-14-2009 |
| 20090260833 | Method and Apparatus to Provide Electrical Connection in a Wellhead for a Downhole Electrical Device - Wellhead assembly and method for providing a power connection to a downhole electrical device, such as a heater. Pressure-containing wellhead body members enclose a vertical wellbore and support therein an isolated tubing hanger and a grounding tubing hanger. The isolated tubing hanger suspends a conducting tubing string, while the grounding tubing hanger suspends a grounding tubing string concentrically spaced from the conducting tubing string. The isolated tubing hanger has an outer housing, an inner electrically conducting portion supported by the outer housing operative to provide electrical connection with, and suspend, the conducting tubing string, and insulation between the housing and conducting portion to electrically isolate the housing portion. Hot electrical connection is made for electrical connection to the conducting portion of the isolated tubing hanger or the conducting tubing string. Electrical isolation seals and electrically isolates the hot electrical connection from the wellhead body members. Grounding connection is provided to a wellhead body member. A source of current provides a first connection to the hot electrical connection and a second connection to the grounding connection. | 10-22-2009 |
