Title: Method and apparatus for drilling boreholes in earth formations (drilling liner systems)
Inventor: HAHN DETLEF
IPC: E21B7/00
Filed: 1999-12-03
Granted: 2006-03-14
Abstract: A drilling liner having a core bit at its bottom end is carried along with a pilot bit on an inner bottom hole assembly driven by a downhole mud motor. In one embodiment, the motor is powered by mud carried by an inner string. Alternatively, the inner string may be omitted and the flow of mud through the liner powers the motor: this requires a locking tool for locking the motor assembly to the outer assembly. Once an abnormally (high or low) pressured zone has been traversed, the liner is set as a casing, the inner assembly is pulled out, and drilling may be resumed using a conventional tool. Directional drilling is accomplished by having an MWD device for providing directional information and having directional devices on the inner and outer assembly.  These include retractable steering pads. Expandable bits, under-reamers and jetting nozzles may also be used in the drilling process. One embodiment of the invention has a bottom thruster between the mud motor and the drill bits that makes it possible to continue drilling for a limited distance even if the upper portion of the casing is stuck.

IPC: H04J13/00
Filed: 1998-05-29
Granted: 2009-07-21
Abstract: A method for synchronising communication of framed data via asynchronous base stations in a cellular communications system, is performed continuously by sending out system frame counter states from a central node in the system to its connected base stations. Each base station comprises a local frame counter which generates local frame counter states correlated to the system frame counter states. Transmission of information via the base stations is synchronised by assigning each data frame a frame number, given by the local frame counter states so that data frames having identical numbers contain copies of a certain data packet.

Title: Automatic telecommunications link identification system
Inventor: KOAY HELENA G
IPC: H04Q3/66
Filed: 2000-01-21
Granted: 2006-06-06
Abstract: A telecommunications network in accordance with the principles of the invention includes one or more controllers that automatically determine the physical interconnectivity between at least two ports adjacently situated in different network elements. Each end-point, that is, each port, has a unique identification. In an illustrative embodiment, upon the occasion of a network modification, such as the addition of a port to the network, the initiation of a port, or reconfiguration of a link, the two ports attached to a communications path to form a link exchange their "view" of the link. That is each port sends an identification message to the other port. Each of these messages includes the identification of the sending port and the presumed identification of the receiving port. If at first the ports don't agree, the receiving port updates its view of the link. This process is repeated until both ports agree on the identification of each port within the link.

Abstract: A process for preparing diced or sliced sausage, e.g. pepperoni, includes the steps of preparing the meat mixture by grinding and mixing to specification. The sausage is stuffed into casings or is extruded into sheet form for fermentation and cooking, following which the cooled meat mixture is chilled to 35°F or lower and sliced or sliced and diced. The product is thereafter conveyed to a spiral dryer where it is exposed to relatively warm (about 50°F to 120°F) air at an initial relative humidity of 50% or less, preferably 30% or less, under turbulent air flow. The dried sausage is then conveyed to a chiller or freezer. Pepperoni prepared in this process has desirable flow characteristics when compared to product made using known pepperoni manufacturing processes. In the most preferred embodiment the conditioned air enters the lower portion of the spiral dryer along with the meat pieces and the resulting product is more consistent than if conventional top/down air flow was used in the dryer.

Granted: 2004-11-16
Abstract: Method of controlling a motorized door by offloading the burden to a separate motion control processor. The method includes generating, in a central processor for the door, one or more signals indicative of a predetermined door speed profile for a stroke of the door. The predetermined door speed profile provides an idea velocity versus are elapsed time since a beginning of the stroke. The signals are communicated to a motion control processor and the motion control processor also receives door position signals from a position encoder. The motion control processor generates signals indicative of the velocity of the door based on the door position signals and it generates error signals based on discrepancies between the velocity of the door and the ideal velocity. It generates motor control signals based on the error signals and the motor control signals are communicated to the motor of the door.

Title: Adjustment mechanism for luminaire
Inventor: GUTIERREZ ANTHONY J
IPC: F21V21/30
Filed: 2001-01-09
Granted: 2010-05-11
Abstract: The present invention provides an adjustment mechanism by which a luminaire may be adjusted and secured along an arc. The adjustment mechanism includes a mounting bracket, adjustment bolt, adjustment brace, which is attached to the optical housing of the luminaire, and a positioning means, such as an eyebolt. The adjustment bolt is threadably attached to the adjustment brace via a non-rotatable nut. The adjustment bolt, which is disposed through the positioning means, is turned in order to adjust the position of the luminaire. As the adjustment bolt turns, the non- rotatable nut, along with the adjustment brace and optical housing attached thereto, moves along the threaded shaft of the bolt. When the turning of the bolt has ceased, the non- rotatable nut, adjustment brace and optical housing are secured in position by the frictional engagement of the thread of the bolt and the thread of the nut.

Title: A portable sail kit
Inventor: BLAD ROBERT CARL
IPC: B63H9/06
Filed: 2001-02-12
Granted: 2004-01-27
Abstract: A "V"-shaped sail is mounted to flexible tubular members. The tubular members are permitted to flex as wind speed increases. This lowers the effective centre of effort and the area of the sail and increases the stability of vessels and vehicles to which the sail is mounted without the need for operator involvement. The sail frame is mounted to a "Y" shaped yoke having a cylindrical stem. The stem is inserted into a locking base that permits rotation of the stem in 30 degree increments while preventing the stem from being removed from the anchor while the sail is set at an operating angle. The locking base can be mounted permanently or temporarily to the vessel and vehicle. One unique aspect of this invention is that no lines (sheets] or similar apparatus are required for any operational function of raising, lowering or sailing this sail kit.
