Title: Dispositif de guidage d'admission pour moteur a combustion interne
Inventor: TAN NAICHENG
IPC: F02M29/06
Filed: 2002-11-25
Abstract: Cette invention concerne un dispositif de guidage d'admission disposé au niveau de la connexion d'un conduit d'admission et d'un couvercle de cylindres pour un moteur à combustion interne. Ledit dispositif comprend des pales de guidage inclinées saillantes à l'intérieur de l'orifice d'entrée dans un couvercle de cylindre pour former un tourbillon dans un cylindre. Dans un mode de réalisation préféré, ledit dispositif de guidage est doté d'une pale de guidage profilée fixée au niveau de l'orifice d'entrée dans le couvercle de cylindre par un rebord. Ladite pale de guidage est dotée d'une partie de tête saillante partiellement dans la chambre de tourbillonnement, dans le couvercle de cylindre, près de la surface latérale de l'orifice d'entrée, afin d'empêcher qu'un flux ne s'écoule à l'intérieur de la chambre de tourbillonnement en avance. Il est préférable que la pale de guidage soit inclinée vers le fond de l'orifice d'entrée, et que la largeur de la tête de la pale soit plus petite. Il est également préférable que la pointe de la tête de la pale soit quelque peu courbée vers l'arrière de la pale.

Patent WO-0065709-A1 (WO)
Inventor: WEIGOLD THOMAS
IPC: H02P6/08
Filed: 2000-04-20
Abstract: L'invention concerne un moteur à commutation électrique dont les enroulements inducteurs du stator peuvent être connectés à une/d'une tension continue d'alimentation et en être déconnectés afin de produire un champ magnétique rotatif pour le rotor à aimants permanents avec une fréquence de commutation. Les enroulements inducteurs peuvent être commutés par l'intermédiaire d'étages terminaux à semi-conducteurs pouvant être commandés au moyen de signaux de commande avec la fréquence de commutation d'une unité de commande et leurs conditions de fonctionnement changent en fonction d'une valeur théorique prédéterminée ou prédéterminable. Il est possible de pallier les inconvénients que présentent des moteurs à commande à modulation d'impulsions en largeur, du fait que la tension continue d'alimentation est acheminée jusqu'à un convertisseur de courant continu dont la tension de sortie pour les étages terminaux à semi-conducteurs avec les enroulements inducteurs change en fonction de la valeur théorique. L'unité de commande utilise toujours pleinement les étages terminaux à semi-conducteurs avec des signaux de commande non synchronisés, avec la fréquence de commutation, indépendamment de la valeur théorique.

Patent DE-1934333-A1 (DE)
Title: Forming coil springs
IPC: B21F3/04
Filed: 1969-07-07
Abstract: Springs are formed round a mandrel that rotates at a constant speed between two end plates, one of which carries a device for holding the end of the wire at the start. During forming, the wire is guided by two fingers carried on a bar that slides along two guide rods and is moved by a lead screw whose speed of rotation is variable. The distance between coils may thus be varied even while forming a single spring, and the machine may be set to work automatically by the use of conventional sensor and control apparatus.

Title: Regeneration of solvents - used to wash acid gases from natural gas, by stripping with flue gases
IPC: C10K1/08
Filed: 1971-05-14
Abstract: The solvent after absorbing the acid components, esp. H2S is first flashed by reducing the press. and then stripped at low press. and raised temp. using flue gas free from O and with min. content of N oxides. The flue gas is pref. made by burning S free fuel gas, pref. the product gas, using insufficient air and the heat generated is pref. used to heat the solvent. Operating costs are low since no external steam is required the desorbed gas contg. little methane can be converted to elemental sullphur. Use of flue gas instead of air prevents formation of sulphur in the solvent. Larger amounts of flue gas than natural gas can be used for stripping, ensuring better solvent regeneration.
