Title: Production of on-demand semi-solid material for castings
Inventor: WANG SHAUPOH
IPC: B22D27/02
Filed: 2001-05-21
Abstract: A method of producing on-demand, semi-solid material for a casting process. A  metal alloy is heated to a molten state which is maintained within a desired temperature range. A portion of the molten alloy is transferred into a processing vessel (42) that includes its own cooling arrangement to facilitate cooling of the vessel (42) and the molten alloy contained therein. A thermal jacket may alternatively be used to facilitate such cooling. A stator (44) creates an electromagnetic field which is applied to the molten alloy to create a stirring action that results in a desired flow pattern of the molten alloy. The electromagnetic stirring begins as soon as the molten alloy is placed in the vessel (42) and continues while the cooling continues in order to create a slurry billet of the desired metallurgical composition. The slurry billet is then discharged from the vessel (42) directly into a shot sleeve (32) of a casting machine.

Title: Machine for front joining and sticking of oblong wood workpieces by toothed front joints and referential procedure
Inventor: LEDINEK PAVEL
IPC: B65G15/00
Filed: 2003-04-03
Abstract: Machine for front joining and sticking of oblong wood workpieces by toothed front joints and referential procedure consists of the flow press and entrance conveying line, and solves the problem of simple and quality front joining and sticking of workpieces, which travel through them fast and fluently in a consecutive row, irrespective of possible yet allowed curvature and dimensional deviation. This is enabled by the construction of entrance conveyors and exit conveyors of the conveying line, equipped with mechanisms for adjustment of side chain units, and with elastic couplings, whereby inside the side chain units the elastic insertions are placed; and inside pressing conveyors ether elastic insertions are placed. Joints among individual entrance conveyors, among individual exit conveyors, and among conveyors are likewise elastic constructions by means of adjustable screws placed between fixed cantilevers, and between tension cantilevers. It is further enabled by the construction of entrance units and exit units in the flow press, or by the construction of pushing wheel pairs inside them, and which are simultaneously driven by the central driving coupling. For this purpose, each wheel pair is equipped with a pair of flexible cranks, the cylinder for pressure adjustment, the cylinder for position adjustment, the mechanism for interactive distance adjustment. Pushing wheel pairs also have the cylinder for the horizontal shift regulation and the shift-meter with which the force meter is connected, and which is placed at the end of the last pushing wheel pair.

Title: Multiple partial encryption using retuning
Inventor: CANDELORE BRANT L
IPC: H04N7/167
Filed: 2003-08-12
Abstract: A partial dual encryption encoder, consistent with certain embodiments of the present invention receives video from a source of an unencrypted digital video signal. A first segment of the unencrypted digital video signal is selected for transmission over a first channel. A first encrypter encrypts a second segment of the unencrypted digital video signal under a first encryption method to produce a first encrypted segment and a second encrypter that encrypts the second segment of the unencrypted digital video signal under a second encryption to produce a second encrypted segment. A multiplexer combines the unencrypted digital video signal with the first and second encrypted segments for transmission, so that the first segment is transmitted over a first channel, the first encrypted segment is transmitted over the first channel and the second encrypted segment is transmitted over a second channel. A trigger message generator generates a trigger message indicating that the second encrypted segment of the digital video signal will be encrypted and will be transmitted on a second channel the multiplexer further combines the trigger message with the first segment, the first encrypted segment and second encrypted segment.

Title: Pilot control valve utilizing multiple offset slide valves
Inventor: ELLIOTT ANDREW C
IPC: F04B9/125
Filed: 2003-08-21
Abstract: A pilot control valve for controlling a reciprocating pump having a valve member shiftable within a valve body between a first or "downstroke" position and a second or "upstroke" position. When the valve member is in its first position, the valve member positions a pair of slide valves to allow communication of control fluid to the lower surface of a piston to move the piston from a first position to a second position. As the piston reaches its second position, a poppet disposed in a rod attached to the piston allows control fluid acting on the valve member to depressurize. As such control fluid is depressurized, pressurized control fluid acts on the valve member to move the valve member from its first position to its second position, In its second position, the valve member positions the pair of slide valves to block communication of the control fluid to the lower surface of the piston and to allow communication of the control fluid to the upper surface of the piston causing the piston to return to its first position. As the piston returns to its first position, the poppet disposed in the piston rod allows the pressurized control fluid acting on the upper surface of the piston to act on the valve member to move the valve member back to its first position. In its first position, the valve member repositions the pair of slide valves to block communication of the control fluid to the upper surface of the piston and allows communication of the control fluid to the lower surface of the piston and the process is repeated.

Abstract: L'invention concerne des procédés et un appareil pour une gestion adaptative d'un ensemble dans un système de communication. Certains niveaux de déséquilibre entre une liaison avale et une liaison inverse sont toujours présents dans un système de communication. Bien que de graves niveaux de déséquilibre provoquent un effet nuisible sur la qualité de la communication et du débit, le déséquilibre devient un problème uniquement si il dégrade le débit d'une vitesse, sur le lien aval. Par conséquent, la gestion adaptative d'un ensemble permet d'évaluer un déséquilibre parmi des secteurs d'une liste de stations d'abonnés, en fonction de la mesure de qualité du lien aval et du lien inverse, et permet de retirer de la liste de stations d'abonnés seulement un secteur qui provoque un déséquilibre grave. Bien que le fait de retenir un secteur dans la liste de stations d'abonnés puisse améliorer le débit, cela peut s'avérer négatif pour d'autres fonctions du système de communication, par exemple, la commande d'alimentation. Par conséquent, un procédé de commande d'alimentation est modifié, si un niveau de déséquilibre affectant la commande d'alimentation est détecté.

Title: Method for fabricating optical fiber preform without hydroxyl group in core
Inventor: LEE CHAN-JOO
IPC: C03B37/018
Filed: 2003-06-26
Abstract: A method for fabricating an optical fiber preform substantially without the use of a hydroxyl group (OH) in a core layer of the fiber. The method includes the steps of (a) forming a clad layer having a relatively low refractive index by depositing soot containing SiO2 and GeO2 on an inner surface of a quartz tube; and (b) forming a core layer having a relatively high refractive index on the clad layer. The core layer is formed as follows: (i) a base core layer forming step having an accumulation process for generating the soot by heating the quartz tube to between approximately 1000°C -- 1400°C  while introducing a reaction gas together with a carrier gas; (ii) a dehydration process for removing the hydroxyl group (OH) and any moisture in the soot and tube by heating the tube to between approximately 600°C - 1200°C while introducing a dehydration gas into the tube; (iii) a sintering process for sintering and vitrifying the soot by heating the quartz to over 1700°C. Finally, an additional core layer forming step is performed to form at least one core layer on the base core layer by repeating the accumulation, dehydration and sintering processes described above at least once.
