Title: Method and apparatus for a contact start plasma cutting process
Inventor: NAOR PETER
IPC: B23K10/00
Filed: 1996-12-13
Granted: 2000-02-08
Abstract: An  plasma  cutter,  including  a  power  supply,  a cutting torch (with a nozzle), a source of air and a valve, is disclosed.  The cutting torch is connected to the two power source outputs (cathode and anode)   Air is supplied to the nozzle through the valve from the air supply.  In one position the valve allows air to flow from the air source to the nozzle.   In a second position the valve prevents air from flowing from the air supply to the nozzle and also vents the nozzle and torch.  The torch has a movable electrode and the nozzle is in a fixed position.  The nozzle and electrode are each electrically connected to a different one of the power outputs.  The electrode is biased (preferably by a spring) to be in contact with the nozzle.  However, air flowing into the torch and electrode overcomes the bias and moves the electrode away from the nozzle.   If the arc is absent and the user desires current, then the valve is moved to prevent air from flowing into the torch and to vent the torch.  Also, the valve is moved to provide air flow (thus purging the torch) when the power supply is powered up.

Title: Method for the concentration of liquid mixtures
Inventor: VEZZANI CORRADO
IPC: B01D1/04
Filed: 1997-10-09
Granted: 2006-12-05
Abstract: The present invention relates to a method for the concentration of liquid mixtures, comprising the step of causing a continuous stream of the liquid mixtures to flow in the form of a turbulent thin layer in contact with a heated wall. For that purpose, a continuous stream of liquid mixture is fed into a turbo-concentrator comprising a cylindrical tubular body (1), a heating jacket (4) and a bladed rotor (8) rotatably supported in the cylindrical tubular body (1). The liquid mixture is centrifuged to form a dynamic and tubular thin layer, the thin layer advancing inside the cylindrical tubular body (1) then being discharged continuously in the form of a stream of concentrated liquid mixture.

Title: Continuous catalytic reforming combined with zeolitic reforming for increased btx yield
Inventor: HAIZMANN ROBERT S
IPC: C10G59/02
Filed: 1997-10-30
Granted: 2006-05-09
Abstract: A naphtha feedstock is catalytically reformed in a combination sequence comprising a continuous-reforming zone, consisting essentially of a moving-bed catalytic reforming zone with continuous regeneration of catalyst particles, followed by a zeolitic-reforming zone containing a catalyst comprising a platinum-group metal and a nonacidic zeolite operating on the effluent from the continuous-reforming zone. The unique process combination permits higher severity, higher BTX aromatics yields and/or increased throughput in the continuous-reforming zone, thus showing surprising benefits over prior-art processes, and is particularly useful in upgrading existing moving-bed reforming facilities with continuous catalyst regeneration.

Abstract: A pneumatic seed delivery system is provided, including a bin with a plenum at the bottom separated from the bin by a membrane to permit the upward flow of air from the plenum into the bin, and a tube extending through a side wall of the bin to provide fluid communication from an outer surface of the bin to an inner surface of the bin. One end of the tube is disposed inside the bin and adjacent to the screen, and a second open end of the first seed distribution tube is disposed outside the bin. In this manner, seed in the bin can be propelled up the tube by forcing air into the plenum, passing the air through the membrane and through seed located between the membrane and the first open end of the tube. This seed will then move up the tube and be carried to a remote location for use. This structure may also be provided by modifying a bin with an existing metering system removable through an opening in the bottom of the bin by removing a cover from the opening, removing the metering device, and inserting a device having plenum and tube structures into the opening.

Inventor: SHILTON MARK GOLDER
IPC: H05F3/06
Filed: 1997-11-14
Granted: 2003-08-12
Abstract: Un pistolet radioactif servant à éliminer l'électricité statique possède une cartouche (7) qui est reliée à une source d'alimentation (8) en air sous pression élevée. Une source radioactive (6) située à l'intérieur de la cartouche (7) génère des particules alpha et suit le même sens que l'axe médian de la longueur. Ces particules alpha viennent en collision avec le flux d'air sous pression élevée passant à travers la cartouche, ce qui génère des ions. Ce dispositif permet à la concentration d'ions d'être plus importante au niveau du coeur du flux d'air, ce qui permet d'effectuer un apport maximum d'ions à la surface dont l'électricité statique doit être supprimée. Ce pistolet radioactif est particulièrement efficace pour supprimer l'électricité statique et adapté pour être utilisé quand on pulvérise de la peinture sur des surfaces métalliques, sur lesquelles les forces électrostatiques au niveau de la surface du métal présentent éventuellement une force insuffisante d'attraction des ions du flux d'air émergeant du pistolet.

Abstract: An application module (A) running on a host computer in a computer network is failure-protected with one or more backup copies that are operative on other host computers in the network. In order to effect fault protection, the application module registers itself with a ReplicaManager daemon process (112) by sending a registration message, which message, in addition to identifying the registering application module and the host computer on which it is running, includes the particular replication strategy (cold backup, warm backup, or hot backup) and the degree of replication associated with that application module. The backup copies are then maintained in a fail-over state according to the registered replication strategy. A WatchDog daemon (113), running on the same host computer as the registered application periodically monitors the registered application to detect failures. When a failure, such as a crash or hangup of the application module, is detected, the failure is reported to the ReplicaManager, which effects the requested fail-over actions. An additional backup copy is then made operative in accordance with the registered replication style and the registered degree of replication. A     SuperWatchDog daemon process (115-1), running on the same host computer as the ReplicaManager, monitors each host computer in the computer network. When a host failure is detected, each application module running on that host computer is individually failure-protected in accordance with its registered replication style and degree of replication.
