Title: Oil and gas well cuttings disposal system with continuous vacuum operation for sequentially filling disposal tanks
Inventor: DIETZEN GARY H
IPC: B63B25/02
Filed: 1997-10-14
Granted: 2007-01-30
Abstract: A method and apparatus of removing drill cuttings from an oil and gas well drilling platform includes the steps of separating the drill cuttings from the well drilling fluid on the drilling platform so that the drilling fluids can be recycled into the well bore during drilling operations. The cuttings are then transmitted via gravity flow to a materials trough (11) having an interior defined by sidewalls and a bottom portion. The drill cuttings are suctioned from the bottom portion of the trough interior with a suction line (22) having an intake portion that is positioned at the materials trough bottom.      Drill cuttings are transmitted via the suction line to a pair of hoppers (204, 205) that each have an interior. A vacuum is formed in sequence within the interior of each hopper using a blower (57) that is in fluid communication with the hopper interiors. The two hoppers are positioned one above the other so that cuttings can be added to the first, upper hopper (204) via the suction line and then fed by gravity to the second, lower hopper (205). A valuing arrangement maintains vacuum within the interior of at least one hopper at all times. A conduit discharges from the lower hopper into a selected holding tank so that a number of holding tanks (209, 210) can be filled in sequential, continuous fashion.

Title: Epoxidation process using serially connected cascade of fixed bed reactors
Inventor: DANNER JEFFREY B
IPC: C07D301/19
Filed: 1998-09-23
Granted: 2008-02-12
Abstract: An olefin epoxidation process is operated using a plurality of reactor vessels, each containing a fixed bed of a heterogenous catalyst such as titania-on-silica. The reactor vessels are connected in series whereby a feedstream comprised of olefin and an active oxygen species is passed through said series of reactor vessels in contact with the heterogenous catalyst to accomplish conversion of the olefin to the corresponding epoxide. As the activity of the catalyst in an individual reactor vessel falls to an undesirably low level, said reactor vessel is taken out of service and a replacement reactor containing fresh or regenerated catalyst introduced. The replacement reactor vessel may, in alternative embodiments of the process, be the first or the last reactor vessel in said series. For example, the feedstream may first be contacted with either the most active or the least active charge of catalyst within the series of reactor vessels. Although the latter embodiment permits somewhat longer catalyst life, the former embodiment requires much smaller capacity heat exchangers. The process of this invention considerably reduces catalyst usage as compared to a conventional fixed bed epoxidation process where all of the catalyst is replaced or regenerated at the same time.

Abstract: A preamble for synchronization, or a reference timing for operation of an OFDM packet communication receiver system is detected finely even under environment of large waveform distortion due to thermal noise and/or multi-path propagation, and/or large carrier frequency offset between a transmit side and a receiver side. A correlator (1) detects a pattern of a short preamble (t1 - t10) in a preamble for synchronization. An output of the correlator (1) is applied to a complex filter (7) which separates a short preamble having a predetermined repetition period from uniformly distributed noise. A scalar filter (9) integrates some period of short preambles which have distributed-delay by multi-path propagation as if a single short preamble with no delay were received for determining a reference timing. When a correlator output exceeds a predetermined threshold level a plurality of times far every repetition periods (T) of a short preamble, and an output of the correlator after time (T) from the last short preamble is decreased a predetermined ratio as compared with that of the last short preamble, it is determined that a preamble for synchronization is detected. Carrier frequency offset compensation is carried out either for each short preamble during reception of a short preamble, or based upon the last received short preamble during reception of an OFDM symbol after the last short preamble. As a preamble for synchronization is detected accurately, a guard interval of each OFDM symbol is removed accurately, or an FFT window is defined accurately, so that a demodulation is possible in spite of noise and/or interference.

Title: Regulateur de moteur
Inventor: LIN HUAI YU
IPC: H02P6/17
Filed: 1999-03-02
Granted: 2008-12-23
Abstract: Le régulateur de moteur de l'invention sollicite des détecteurs permettant de connaître la vitesse de rotation et la position relative du rotor de moteur. Le régulateur produit un vecteur de tension destiné à conserver le courant du moteur en phase avec la force électromotrice avant d'atteindre la limite de tension. Le calculateur calcule une vitesse réelle approchée et des signaux de position. Le calculateur prend alors la vitesse réelle et la compare au signal de vitesse de commande, et en cas de différence, il produit un signal d'erreur. Un intégrateur proportionnel qui reçoit le signal d'erreur produit un signal de correction destiné à un rotateur de vecteur. Ce signal de correction correspond à la composante tension verticale nécessaire à l'obtention de la vitesse de commande. Une fois que la tension limite a été atteinte, toute augmentation ultérieure de vitesse demandée résulte d'une rotation du vecteur de tension dont l'amplitude reste inchangée.
