Title: High pressure fluid seal for sealing against a bit guide in a wellhead and method of using
Inventor: DALLAS L MURRAY
IPC: E21B17/10
Filed: 1999-04-23
Abstract: High pressure fluid seals for sealing against a bit guide in wellhead and a method of using the seals are described. The high pressure fluid seals are primarily intended for use with a blowout preventer protector. The high pressure fluid seals are elastomeric material bonded to an end of a mandrel for insertion into the wellhead.      The end of the mandrel includes an annular ridge that protrudes into the elastomeric seal to inhibit the seal from being extruded away from the bore when the elastomeric seal is seated against the bit guide and the bore is subjected to elevated fluid pressures. The advantage is a high pressure fluid seal that ensures packoff against a bit guide even if the bit guide is worn but still serviceable. A further advantage is a more secure seal that improves safety and enables the use of higher pressures during well stimulation.

Title: Automatic deicing unit
Inventor: ASK BERNARD J
IPC: E04D13/10
Filed: 1998-02-12
Abstract: The present invention is a stationary, portable deicing machine (31) for preventing snow and ice build up on any targeted surface, such as driveways, walkways, and rooftops. The invention is a compact, integrated reservoir/pump/controler system that may be operated manually, automatically or by remote control. The invention is easily maintainable and may be left in a state of preparedness for use in the event of icing conditions. The liquid chemical deicing agent is contained in a temporary reservoir tank (16) that is manually replaced. The temporary reservoir tank (16) is placed upon the watertight base (1). The deicing agent is pumped from the watertight base (1) to the distribution system (51). Apertures in the distribution system (51) allow for the deicing agent to be distributed to any targeted surface. A  primary benefit is a greatly increased margin of safety for the users of driveways, walkways, etc. to which the invention applies the deicing agents.  Another benefit is a reduction in the injuries and deaths related to the physically strenuous activity of shoveling snow and ice.

Abstract: The invention relates to a shaping method for use by a shaper in a communication network in order to convert an incoming data flow with an incoming data packet rate into an outgoing data flow with an outgoing data packet rate. The shaper includes a buffer which is leaked with the outgoing data packet rate in order to provide thereby the outgoing data flow.      The shaping method includes the following steps: - determining a value of a future incoming data packet rate of the incoming data packet rate; and - determining a value of a buffer occupancy related to the number of data packets of the incoming data flow which is received and actual buffered by a buffer included in the shaper; the buffer is leaked with the outgoing data packet rate in order to provide thereby the outgoing data flow; and - determining a value of the outgoing data packet rate in function of the value of the future incoming data packet rate and the value of the buffer occupancy.      The shaping method further includes the step of: - determining a value of the outgoing data packet rate also in function of a predetermined peak data packet rate and a predetermined minimum data packet rate. Herewith the shaper is enabled to support a service category which provides a service with a predetermined minimum guaranteed bandwidth according to the predetermined minimum data packet rate and which allows use of excess bandwidth over the predetermined minimum guaranteed bandwidth whereby the excess bandwidth is limited according to the predetermined peak data packet rate.

Title: Semiautomatic tube welding
Inventor: LAGEOSE MICHAEL M
IPC: B23K9/12
Filed: 1999-09-15
Abstract: The present invention relates generally to an apparatus and method for performing tube-to-tubesheet welding within box headers and, in more particular, to a GTAW welding gun that has a long generally tubular barrel which is small enough in diameter to pass through the plug holes on one side of a box header and long enough to reach over to the point of connection on the opposite tubesheet. Additionally, and as a critical part of the instant invention, the torch is fitted with a semi-automatic cold wire feeding apparatus and an associated wire feed liner that is constrained to be proximate to the exterior of that tube throughout said barrel's length. Thus, both the barrel of the welding torch and its accompanying wire feed liner are sized to fit within and pass through a plug hole.

IPC: H01J61/12
Filed: 2000-01-14
Abstract: Rare-earth halides are shown to be a replacement for scandium halides in mercury-free discharge arc lamps if modifications are made to the prior art lamp design and operating temperatures. The inventive chemical compositions of the discharge medium provide enhanced color rendition index values. In addition, it has been unexpectedly determined that during the operation of the discharge lamps, the rare earth iodides do not react significantly with the fused silica arc tube. Equally as significant, any free iodine, which is so formed, has minimal impact on the efficacy of the lamp compared to the conventional scandium iodide lamps. Therefore, the rare earth iodide-containing lamps provide longer lifetime with superior illumination characteristics than conventional discharge lamps.
