Patent WO-9204808-A1 (WO)
Inventor: WONG SIEW EAN
IPC: H05B41/28
Filed: 1991-08-29
Abstract: Circuit à ballast pour une lampe fluorescente compacte dans lequel on augmente le facteur de puissance en introduisant une diode (D2) pour commutation rapide, après le pont redresseur (D1) mais toutefois avant les condensateurs de filtrage (C5, C6). La diode commutatrice fonctionne pour empêcher l'alimentation en courant de la lampe fluorescente d'être entièrement assurée par le ou les condensateurs de filtrage durant les parties de la demi-période pendant lesquelles la tension d'alimentation est inférieure à la tension en courant continu au niveau du ou des condensateurs de filtrage.
Patent WO-9302779-A1 (WO)
Inventor: KOPP VIRGIL CLINTON
IPC: B01D61/14
Filed: 1992-08-07
Abstract: Un ensemble de filtre microporeux est décrit, dont la pression d'alimentation, dans certains modes de fonctionnement, est appliquée aux parois externes des fibres microporeuses (13) composant le filtre. Sous d'autres formes, l'alimentation est dirigée à travers les parois des fibres (13) par l'application d'une pression plus basse dans les ouvertures des fibres (13). Différentes méthodes de lavage à contre-courant des fibres (13) sont décrites, dont aucune ne requiert une étape de pré-pressurisation de l'environnement à l'intérieur et autour des fibres (13) avant le début du lavage à contre-courant. Dans des méthodes spéciales de lavage à contre-courant, les étapes initiales comprennent l'arrêt de l'alimentation vers les surfaces externes des fibres (13) et l'enlèvement substantiel des filtrats des ouvertures des fibres (13). Dans quelques versions le filtre comprend une cartouche de filtre (10) ayant un paquet de fibres (13) contenu dans une coquille (12) fermée et pressurisable. Dans d'autres versions le filtre comprend un ou plusieurs paquets de fibres (102) suspendus dans une enceinte ouverte (101). L'invention diminue le nombre requis de cycles de pressurisation de l'environnement à l'intérieur et autour des fibres (13). Dans certains cas, une telle pressurisation est éliminée.

Title: Method and apparatus for cooling and dehumidifying air
Inventor: PARADIS MARC A
IPC: F24F3/14
Filed: 2003-02-26
Abstract: A method and an apparatus for rapidly cooling and dehumidifying air within a space. In this method, air to be cooled and dehumidified is forced into a cooling zone including an evaporator (101) having fins (103) forming air channels. The fins and the air channels are preferably substantially vertical. Air is circulated between the space and the cooling zone in such a manner that the air circulates within the air channels and droplets of condensed water resulting from condensation are evacuated from the cooling zone. One advantage of the above method and apparatus for carrying out the same is that the evaporator can be completely cleaned and sanitized in a few minutes. Since the apparatus allows rapid shedding of any condensation off of the evaporator, freeze-ups never occur. Defrosting is thus eliminated, saving precious time and electrical energy. The above apparatus is particularly adapted for rapidly cooling food.

Abstract: ROTATABLE PLASMA TORCH              ABSTRACT OF THE INVENTION           An improved plasma torch having a rugged configuration, which is easier to start, and which eliminates the need for fragile and possibly metal contaminating insulators from the lower end of the plasma torch.  To prevent double arcing from occurring and to enable the elimination of costly insulators from the nozzle area, the electrode and nozzle of the plasma torch of a first embodiment of the present invention are rotated as a unit at a speed in the range of 0 to 400 rpm.  In a second embodiment of the invention, the nozzle assembly rotates relative to the electrode which is normally stationary.  The electrode and nozzle could rotate in opposite directions as well.  When the nozzle assembly is rotated, the resident arc time would be of such short duration due to the spinning of the nozzle that serious damage to the nozzle would not occur.  The rotating nozzle can be advanced into an area and, should it strike an unexpected obstruction, the possibility of damage to the nozzle or to the outer electrode area will be greatly reduced or, in most cases, eliminated.  The rotating nozzle will also enhance torch starting with a pilot are as the arc transferred from the nozzle to the work piece will transfer from the plasma torch electrode to the work piece when the torch is withdrawn or moved to eliminate the double arcing.

Abstract: ABSTRACT OF THE DISCLOSURE An improved discharge chute assembly for use with a concrete mixing truck includes improved chute components which are fabricated from a high strength, lightweight polymeric material.  The polymeric material tends to remain smooth during wear, and permits chutes according to the invention to be manufactured much lighter than those heretofore known. According to a second aspect of the invention, an improved connecting joint structure is provided which is simple to connect and disconnect, and will not become jammed with wet concrete.  Both the chute components and joint structure are constructed with smooth outer surfaces to avoid catching on clothing or other fabric.  The combination of lightweight chute components and the improved joint structure yields a discharge chute assembly which is safer and more efficient to deploy at a construction site.
