Abstract: A single cathode plasma gun injects powder therein so that the powder exits along a central axis of an exit barrel of the gun, in order to provide improved coatings of the powder material on a workpiece. The central axis of the single cathode extends from an arc chamber and intersects with the central axis of the exit barrel so as to form an acute angle which is substantially greater than 0° but no greater than 90°.  Examples of the acute angle include 45° and 10°.  A powder feed passage extends along an axis which may be coincident with the central axis of the exit barrel or may form an angle with the central axis of the exit barrel of as much as 45°.  Consequently, the axis of the powder feed passage forms an angle with the central axis of the single cathode which is at least as great as the acute angle between the central axes of the single cathode and the exit barrel.  Existing plasma guns can be retrofitted with a new anode attachment to achieve desired angles of plasma flow and powder delivery.  Where the central axis of the single cathode forms an acute angle with the central axis of the exit barrel, the resulting bend in the passage extending from the arc chamber below the single cathode is disposed adjacent an entry end of the exit barrel, and the powder feed passage terminates adjacent such bend.  Alternatively, the powder can be introduced into the middle of the plasma stream at the entry end of the exit barrel by a powder injector extending into the exit barrel from the wall of the passage.  The single cathode can be axially adjusted to move the charged plasma region adjacent the termination of the powder feed passage, for more effective heating of the powder.  The angles formed by the central axes of the single cathode and the powder feed passage relative to the central axis of the exit barrel can be adjusted relative to each other so that the injected powder is deflected along the central axis of the exit barrel, again providing for an improved coating of the powder material on a workpiece.

Abstract: Procédé de pasteurisation et de fermentation trouvant application dans la production d'une boisson alcoolisée. Ce procédé consiste à extraire un extrait soluble fermentescible d'une maische de brasserie, à le mélanger dans une zone de mélange avec un extrait fermenté renfermant de l'alcool à raison d'au moins 4 % en volume, ainsi que d'autres produits formés au cours de la fermentation, à traiter ce mélange par chauffage jusqu'à une température d'au moins 51  DEG C (124  DEG F), à maintenir le mélange à cette température pendant dix à vingt minutes, puis à refroidir le mélange jusqu'à une température d'au moins 10  DEG C (50  DEG F), et à réaliser la fermentation du mélange selon des processus de fermentation connus. Dans le but d'obtenir un processus à débit continu et une meilleure régulation de la densité de l'extrait fermentescible non fermenté, on peut transformer l'extrait liquide de maische en un produit pulvérulent soluble à partir duquel on peut ensuite former un débit continu de produit pulvérulent afin de le dissoudre dans un débit continu d'eau et d'obtenir un débit continu d'extrait soluble fermentescible destiné à se mélanger au débit continu d'extrait fermentescible fermenté prélevé à la sortie d'une installation de fermentation continue. On traite le mélange de la façon précitée avant de l'introduire dans l'installation de fermentation continue, où on le fait subir une fermentation afin de produire la boisson alcoolisée.

Title: Method and apparatus for using full spectrum transmitted power in a spread spectrum communication system for tracking individual recipient phase time and energy

Abstract: Method and apparatus for tracking the frequency and phase of signals in spread spectrum communication systems that makes more efficient use of available carrier frequency and phase information by utilizing a substantial portion or all of the energy occupying the frequency spectrum of a received carrier signal, including energy from communication signals intended for other system users. Multiple spread spectrum communication signals ( 182) are input in parallel to data receivers (126 A'-N') where they are despread using preselected despreading codes at an adjustable phase angle and decoded over multiple orthogonal codes active within the communication system. Multiple decoded signals are then combined ( 188) to form a single phase detection signal which is used by at least one tracking loop (184) to track frequency and phase of the carrier signal for the received communication signals. The tracking loop (184) generates a timing signal which is used to adjust the phase angle (186) used during despreading. In further embodiments, the communication signals are despread using appropriate PN codes and separated into in-phase (I) and quadrature channels (Q) (214) where data symbols are processed by fast Hadamard transformers (218, 220) to generate corresponding data bits. The data is formed into pairwise products between the channels (224), and summed over multiple or all active subscriber orthogonal codes (226). This sum indicates a degree to which the estimated phase differs from the actual phase of received communication signals and is used to adjust the phase of application for the PN codes (230).

Filed: 1998-03-02
Granted: 2003-05-06
Abstract: A device for connecting a VSC converter to a source of alternating voltage having multiple phases through a plurality of inductances. The VSC converter provides a direct current voltage to a capacitor for a power transmission plant. A first circuit breaker connects the inductances to the source of alternating voltage and selectively interrupts current from each of the multiple phases. An additional circuit breaker is connected between one of the phases of the first breaker and the VSC converter. A resistor is connected across the first circuit breaker for supplying current from the one phase to the additional breaker when the first circuit breaker is in an open condition. A circuit connected to a d.c. voltage output of the VSC converter changes the first circuit breaker from an interrupting condition to a closed condition when a d.c. voltage has been established at the output of the VSC converter.

Title: Method and arrangement for channel allocation in a radio communications system
Inventor: BEMING PER JOHAN
IPC: H04Q7/22
Filed: 1997-02-12
Granted: 2006-07-04
Abstract: The present invention relates to a method and an arrangement for channel allocation in a radio communication system in which data is transmitted between two stations over two or more radio channels (SPDCH3-SPDCH7). Data is communicated as packets which are divided into blocks (b1-bm) while the transmission follows a protocol for automatic re-transmission of data that have been erroneously transmitted. In accordance with the proposed method, channels for re-transmission (SPDCH5, SPDCH6) are allocated with respect to a transmission parameter (TP), which has been created at a previous transmission and which is based upon information of the result (Nack) of said previous transmission. The transmission parameter (TP) is aimed to ensure that re-transmission is performed via those channels (SPDCH5, SPDCH6) which have the highest probability of transmitting data correctly. The channels (SPDCG5, SPDCH6) which had the highest transmission quality in said previous transmission are expected to have the highest transmission quality also by re-transmission.

Abstract: An apparatus and method for removing the distortion in marine seismic data resulting from the motion of the ship. The ship trails one or more seismic sources and receivers and moves forward at a known velocity. The seismic sources emit seismic waves that travel through the water and reflect off interfaces between rock formations below the ocean floor. The motion of the sources and receivers introduces distortion in the recorded seismic data that can be modeled using Doppler theory. The data preferably is corrected for source motion independently from the correction for receiver motion. The seismic data is first corrected for receiver motion and then for source motion The technique for correcting for source motion includes correlating the receiver-corrected data with a reference sweep signal, performing an F-K transform, performing an inverse F-K transform on a selected subset of the F-K transformed data, and computing appropriate correction filters for the data resulting from the inverse F-K transform. This process is repeated for all subsets of F-K  transformed data and the resulting filtered data are summed together.
