Patent EP-0357805-B1 (EP)
IPC: F28F21/06
Filed: 1988-08-06
Granted: 1992-05-06
Abstract: A crossflow cooling tower (10) has a number of fill structure sections (46) which are arranged at equally spaced intervals around the entire perimeter of a central plenum (52) that receives generally horizontal currents of air simultaneously from all of the fill structure sections (46) and causes the air to be discharged in an upwardly direction out of the tower (10). In one embodiment, the tower (10) is provided with four upright fill structure sections (46) disposed in a square arrangement in horizontal view, and a number of the towers (10) may be located adjacent each other in a side-by-side diamond-like arrangement so that each air inlet face (48) of each tower (10) readily communicates with the atmosphere. Both the hot water distribution basin (14) and the cold water distribution basin (16) are formed as integrally molded, one-piece components, and four upright air baffle corner supports (56) carry the weight of adjacent fill structure sections (46) as well as the load presented by the overhead hot water basin (14), thereby minimizing the need for additional supporting members, bracing or casings to provide necessary structural integrity.

Abstract: The invention relates to a process for desludging phosphatizing baths, in which a part volume of the phosphatizing solution is fed continuously to an apparatus which has three open chambers and in the oxidation chamber of which an O2-containing gas is passed into the solution, after which the resulting iron phosphate sludge is conditioned in the sludge conditioning chamber and is separated off and disposed of in the sedimentation chamber and thereafter the solution having a lower content of layer-forming components is supplemented with aqueous solutions which permit the acidity and the concentration of the layer-forming components to be adjusted to the desired range. The invention also relates to an apparatus for carrying out the process, which has an oxidation chamber 11 having a gassing unit 13, a sludge conditioning chamber 15 and a sedimentation chamber 19, the individual chambers communicating with one another via overflows 14 and 18, and the sedimentation chamber 19 permitting the deposition of the sludge via several partitions 24 arranged essentially parallel to the direction of flow into a sludge nipple 20 having a separate sludge discharge 23.

Abstract: Frequency tuning and coupling capacitances in MRI RF receive coils (14) are typically realized, at least in part, as reverse biased varactor diodes. During RF tuning of the transmit (12) coil (i.e., so as to achieve resonance and matched impedance conditions), at least some if not all of the varactors associated with the receive coil are forward biased so as to simultaneously maximize detuning of the receive coil to resonant frequencies removed as far as possible from that of the transmitter coil being tuned while also then substantially reducing the Q of the receive coil.

Title: Method and apparatus for packaging a food or other product in a tray
IPC: B65B31/02
Filed: 1988-10-19
Granted: 1990-12-27
Abstract: This method and this apparatus are designed for the packaging of a food or other product in a shallow display tray to which is attached a thermoplastic film, welded on its edges. Before welding of this film inside a leaktight chamber (1-2), under vacuum, the portion (4) of this film (3) which is located inside this chamber is heated, whilst the tray (8) to be closed and its contents (P) are placed beneath this film. This tray (8) is then lifted into a position such that its contents (P) press into the corresponding portion (4) of the film so that the latter completely encases the projecting part of this product. After the film (3) has been welded, under vacuum, onto the peripheral rim (13) of the corresponding tray, the vacuum is released so that the corresponding portion (21) of the film is applied closely over the projecting part of the product. This method and this apparatus may be used for the packaging of various products, particularly food products. <IMAGE>

Abstract: Lorsque la sortie d'un laser à oscillation continue doit être pulsée en utilisant un commutateur en Q, le procédé conventionnel utilisant ce commutateur en Q pose le problème que lorsqu'une fréquence est modifiée, les conditions d'excitation de l'oscillation se modifient également, et une onde impulsionnelle et une sortie de crête changent simultanément, de sorte qu'il n'est pas possible d'effectuer la finition mate de manière stable. La présente invention permet de limiter la perte d'un oscillateur laser pedant la période ''HORS SERVICE'' de l'impulsion en réduisant la sortie d'un signal haute fréquence destiné à être appliqué au commutateur en Q et commande l'onde impulsionnelle pour qu'elle se situe dans une gamme appropriée pour la finition mate des cylindres. Le procédé ci-décrit permet d'obtenir une surface mate très satisfaisante.

Abstract: Procédé de commande numérique de la vitesse et du courant d'un servomoteur. On applique des valeurs de correction (23, 27) de sorte que le gain d'intégration (22) et le gain proportionnel de boucle (26) de la boucle de commande de courant augmentent en fonction de la vitesse du servomoteur. Etant donné que la boucle de commande de courant augmente en fonction de la vitesse du servomoteur, il ne se produit aucune oscillation dans la boucle de courant lorsque le servomoteur tourne à basse vitesse ou est à l'arrêt. Il est en outre possible d'empêcher une diminution du couple provoquée par la diminution du gain de boucle de courant pendant le fonctionnement à grande vitesse.

Title: Process for manufacturing semi-finished products from sintered refractory metal alloys
IPC: B22F3/24
Filed: 1988-10-24
Granted: 1992-10-21
Abstract: In a process for manufacturing semi-finished products from sintered refractory metal alloys with a stacked microstructure, the sinter feed formed at least at 85 % is subjected prior to subcritical annealing to an intermediate annealing for at least 20 minutes at a temperature not less than 700°C and not greater than that at which no further recrystallization occurs. Following this intermediate annealing, the hot feed is deformed by a further 3 % to 30 %. The process makes it possible to manufacture semi-finished products with a good stacked microstructure and of substantially greater dimensions or of the same dimensions and a substantially better stacked microstructure than can be obtained with known manufacturing processes.

Abstract: A fluid-power cylinder comprising a power cylinder member (11) and a power piston member (12) reciprocable therein between end positions includes a device for cushioning the relative movements of the power piston member and the power cylinder member adjacent the end positions. The cushioning device comprises a cushioning cylinder (13) movable together with the power piston member (12) and a cushioning piston (14) which is stationary with respect to the power cylinder member (11) and which is receivable and axially movable in the cushioning cylinder to define a cushioning cylinder compartment (31A, 31B) having a restricted discharge passage (37/38, 40/41). A seal (36A, 36B) on the cushioning piston (14) acts as a one-way valve to prevent flow of cushioning fluid between the cushioning piston (14) and the cushioning cylinder (13) when the cushioning piston moves inwardly in the cushioning cylinder compartment (31A, 31B) and thereby reduces the volume of the compartment, but allows substantially unrestricted fluid flow when the cushioning piston moves outwardly.

Ce procédé est caractérisé en ce que le moment où les différentes bobines d'allumage du moteur à combustion interne sont mises sous charge est déterminé à l'aide d'un compteur supplémentaire unique, où la position se modifie en fonction du signal de synchronisation variant avec l'angle et qui reçoit pour chaque bobine une valeur initiale qui correspond à l'intervalle restant jusqu'au début de la mise sous charge de la bobine suivante. Ainsi, tandis que le premier compteur déclenche le processus d'allumage, le second compteur détermine le moment où une bobine d'allumage sera mise sous charge.
