Title: Converter circuit arrangement having a dc intermediate circuit
Inventor: STULZ CHRISTIAN
IPC: H02M1/12
Filed: 1998-12-09
Abstract: The invention relates to a converter connection assembly with a direct voltage intermediate circuit (3) containing a transformer (8) with at least two windings (9 and 10). The transformer is connected in the intermediate circuit (3) in such a way that the undesired, asymmetric current components lead to a magnetization of the transformer core, and are thus suppressed. A grounded LC filter (Lf, Cf) is connected in front of the load (6). The filter effects a sinusoidal voltage on the load (6). As a result, the connection can be utilized with any polyphase machines and also during the expansion of existing systems.

Title: Supplemental charge for hydrostatic steering system
Inventor: HOU YIFEI RAYMOND
IPC: B62D11/18
Filed: 2000-08-03
Abstract: A supplemental charge for a hydrostatic steering system is provide by coupling the output of the transmission oil pump to the outlet of the steering charge pump and providing a check valve to prevent oil flow from the transmission oil pump to the steering charge pump unless the charge pump outlet pressure drops below the operating pressure of the transmission pump. When the steering charge pressure does drop below the transmission oil pressure, the check valve opens and oil is provided to the main steering pump by the transmission oil pump. A  pressure transducer in the oil line activates a warning signal in the event the check valve is open more than a few minutes to alert the vehicle operator to a system failure.

Title: Heating furnace, especially with gas and/or oil firing
Inventor: AIDELSBURGER JOHANN
IPC: F24H7/02
Filed: 1998-11-20
Abstract: According to the invention, the heating furnace has a combustion chamber (2) and heat accumulating bodies which surround said chamber.      Each first heat accumulating body (3, 4; 27) is arranged parallel to the respective wall (5, 6; 24) of the combustion chamber (2) at a first distance.      Each second heat accumulating body (12, 14; 25) is also placed parallel to the respective outer side of the first heat accumulating body at a second distance. A first air canal (16, 17; 28) is obtained as a result of the first distance, and a second air canal (15, 18, 26) is obtained in each of the configurations as a result of the second distance. The air in the first air canal is heated by the walls of the combustion chamber, ascends, cools on the surrounding heat accumulating bodies and descends downwards in the second air canal to the heat accumulating bodies during additional delivery of heat. Afterwards, the cooled air returns to the first air canal and the described cyclic flow begins again in the inventive heat exchanger.

Patent CA-2331932-A1 (CA)
Inventor: BETANCOURT PAREJA WILSON ANCIZ
IPC: E21B43/12
Filed: 2001-01-23
Abstract: The mechanical load equalizer concerns to petroleum engineering. It could be used in the mechanical pumping system. The mechanical load equalizer consists in a reduction of loading of the sucker rods by helical compression springs mounted in it. The failures of the sucker rod string are due to the weight of well-pumped fluids on the piston of the bottom-reciprocating pump. The reduction of the failures of sucker rods results in their increase of work services.    The sucker rods in a reciprocating pumping system are the most important elements between the bottom reciprocating pump and superficial mechanical pumping unit.   The mechanical load equalizer is a unique mechanism, which is installed over the reciprocating pump to reduce the stress of the sucker rods.  The sucker rods are submitted to many efforts in the pumping process that act into failures. They have many connections and are actually the weakest part of this artificial lifting system. The weight on the sucker rods develops of the following basic forces: 1) static load from weight of sucker rods and fluids on it. The friction forces of sucker rods on the inner surface of the pipelines and the friction force between the piston and surrounding casing cylinder of reciprocating pump. 2) A force of inertia of driving weights; 3) various dynamic loads.      The sucker rods could be broken due to metallic fatigue. During the pumping process the production pipelines work in a considerable safe range of load. A packer connects the mechanical load equalizer with the production pipelines thus, it helps to sucker rods to decrease the stress forces.

Abstract: L'invention concerne un serveur (100) d'échange de données dynamique (DDE) permettant à des programmes externes d'accéder à des données de gestion. Ce serveur DDE (100) permet d'obtenir une référence croisée mnémonique entre des articles de registre et des noms de paramètres alphanumériques standardisés. Cette interface mnémonique permet à l'utilisateur d'extraire des données depuis un dispositif sans connaître le nombre réel d'articles de registre du dispositif. Ce serveur DDE (100) est optimisé pour le protocole Modbus RTU ou Ethernet. Ce serveur DDE (100) joue le rôle d'un lien entre un client demandant des données de dispositif et un dispositif client pouvant fournir ces données. Ce serveur DDE (100) communique au dispositif client par l'intermédiaire de ports de communication et avec le client par l'intermédiaire d'un lien de message DDE ou NetDDE. Le client envoie ses demandes au serveur concernant l'enregistrement et la lecture de quelques enregistrements du dispositif. Ce serveur met en correspondance chaque demande avec des paquets appropriés de demandes d'enregistrement et d'écriture de dispositif et exécute la transaction nécessaire avec ce dispositif. Il retransmet ensuite le résultat au client après avoir traité et reformaté correctement les données recueillies du dispositif. Afin de configurer le serveur DDE (100), l'utilisateur peut exporter et importer des fichiers contenant des groupes de registres et des mnémoniques en formats de valeur séparés par une virgule. L'importation et l'exportation de groupes de registres et de mnémoniques permettent à l'utilisateur de modifier la cartographie du registre de révision de logiciels programmés ou les mnémoniques d'une catégorie de dispositifs supportée par le serveur DDE (100), de modifier le nombre ou les types de registre ou de mnémoniques ou d'ajouter un nouveau type générique de dispositif.

Abstract: A system and method for generating a multidimensional navigation solution utilizes Global Positioning System (GPS) data to obtain highly reliable and accurate navigational solutions in high interference and dynamic environments, at a performance level which has been heretofore unattainable. Additional sensors such as inertial (gyros and accelerometers), altimeters, radars, etc.  may be employed in a deeply integrated configuration. The approach taken in the present invention differs from that of previous techniques through its exploitation of nonlinear filtering methods; as a result, the navigation system architecture and processes employed yield significant improvements in navigation system performance, both in code tracking and reacquisition, and in carrier tracking and reacquisition. The improvements are particularly significant at low signal/noise ratios, where conventional approaches are especially susceptible to loss of code lock or carrier lock.
