IPC: B67B7/18
Filed: 2001-10-03
Abstract: A semi-automatic opener for a jar closed by a threaded cover comprises a base for receiving a jar thereon and an upper portion superimposed to the base. A  first turntable is rotatably mounted to the base via a rotatable shaft that is coupled to a motor. A first toothed rack is mounted to the first turntable and has a first central gear coaxially mounted to the rotatable shaft and a first pair of rack elements each interlocked to the first central gear for reciprocating movement towards and away each other upon rotation of the first central gear.  A first pair of jaws is respectively secured to a rack element of the first toothed rack and allows immobilizing the jar. The second portion also includes a pair of jaws mounted to a second toothed rack. In operation, the jar is positioned onto the base and the second portion is lowered for abutment with the cover. Then, activating the motor causes the rotation of the rotatable shaft, which in turn causes the rotation in unison of the first and second turntables with the jar.    Since the rotation of the second turntable causes the closing of the upper jaws on the cover of the jar, the rotation of the jar is stopped when the second pair of jaws grips the cover. The jar and the upper portion of the jar opener are then immobilized while the lower jaws move towards the jar since the motor is still energized and the first turntable is fixedly mounted to the rotating shaft.  The cover being immobilized, the rotation of the jar results in its opening.

IPC: G06F9/44
Filed: 2001-10-31
Abstract: A method and apparatus for the data-driven synchronous parallel processing of digital data, which temporally separates the processes of instructions distributions and data requests from the process of actual data processing. The method includes the steps of: dividing the stream of digital data into data packets, consecutively distributing instructions to data processing units before their execution, consecutively synchronously processing data packets by multiple data processing units processing in parallel, and synchronization of parallel multiple data processing units by data tokens attached to the data packets. In the preferred embodiment the method comprises one or more of the steps of storing instructions inside the data processing units, requesting data before the start of data processing, storing records for requested data packets, associating received data with the records of data requests, attaching to each data packet a validity signal (data token) indicating the validity or non-validity of the received data for processing, and extension of data buffers coupled to the data processing units into elastic data buffers capable of absorbing variations in the data rate. The method provides a data-driven synchronization of parallel synchronous multiprocessor system and a substantially non-stalling flow of digital data through a digital data processor, and the apparatus includes a programmable apparatus which implements the method. In the preferred embodiment a data buffer is provided between adjacent data handling units, and the invention manipulates the timing of the buffer's emptiness and fullness signals, processing each data packet coming into buffer in accordance with its validity signal (data token), and associating a validity signal (data token) with the data packet sent out from buffer.

Title: Rotary seal for directional drilling tools
Inventor: GRIFFIN NIGEL DENNIS
IPC: E21B10/42
Filed: 2002-03-28
Abstract: A rotary valve assembly for a rotary steerable tool is disclosed for directing flow of an abrasive laden drilling fluid; the valve assembly has a first sealing surface rotatably engaging a second sealing surface. At least one of the surfaces has at least about 5% of its area comprising interconnecting voids to an average depth of at least 0.02 mm. The interconnected voids allow fluid pressure to equalize between the sealing faces by flowing through the interconnecting voids to the sealing surfaces. Because the fit of the sealing surfaces of the valve is less than perfect, and because the voids on mating surfaces do not necessarily overlap, the 5% of the surface area comprising interconnected voids can easily translate to a 10% or more reduction in sealed area when both sealing surfaces have the interconnecting voids. The additional reduction in surface area subjected to differential pressure has substantially eliminated the hydraulic lock problem previously encountered upon startup.
