Patent CA-2394270-C (CA)
Inventor: WOOD MICHAEL ANTHONY
IPC: C07C31/20
Filed: 2000-12-12
Granted: 2010-02-16
Abstract: L'invention concerne un procédé permettant de produire à la fois un produit à base de diol (par exemple, du butane-1, 4-diol) et un éther cyclique (par exemple, un tétrahydrofurane) par hydrogénation d'un diester aliphatique ou produit de départ à base de lactone, tel que le diméthyle ou le maléate de diéthyle, contenant une faible quantité d'une matière acide, telle que le monoester correspondant. Ce procédé utilise une pluralité de zones d'hydrogénation (8, 9, 10) connectées en séries; chacune des zones contenant une charge (12, 17, 24) d'un catalyseur d'hydrogénation d'ester en grain. La première zone d'hydrogénation (8) contient un lit (12) d'un catalyseur (par exemple, du chromite de cuivre bivalent réduit) lequel accepte une faible quantité de matière acide, alors que la deuxième zone d'hydrogénation (9) contient un lit (17) d'un catalyseur fournissant des rendements améliorés d'éthers cycliques par rapport au catalyseur de la première zone d'hydrogénation (8). Une troisième zone d'hydrogénation (10) contient un lit (24) d'un catalyseur présentant une sélectivité peu élevée lors de la transformation du diester en au moins un sous-produit (par exemple, 2-(4'hydroxybutoxy)-tétrahydrofurane). La charge est fournie à la première zone d'hydrogénation (8) sous la forme d'un flux en phase vapeur comprenant de l'hydrogène et la matière pouvant être hydrogénée; les zones (8, 9, 10) étant généralement activées dans des conditions adiabatiques. Un flux de produit fini est récupéré à partir de la troisième zone (10); ce produit est essentiellement exempt de ladite matière pouvant être hydrogénée et il contient le diol, l'ether cyclique et d'autres sous-produits; la sélectivité à l'ether cyclique étant supérieure dans le flux de produit fini que dans le premier flux de produit intermédiaire.

Title: Projector headlamp
Inventor: TOKORO YOSUKE
IPC: F21Y101/00
Filed: 2002-09-13
Granted: 2012-04-17
Abstract: A conventional projector headlamp has low efficiency because an amount of light is shaded almost half by a shutter for a low-beam light distribution. In addition, only a projection lens is seen in the installed condition, inviting old-fashioned designs disadvantageously. In a projector headlamp (1) of the invention, a vertical section passing through the center of a projection lens (5) includes a convex front surface and a flat rear surface (5a) . A line connecting the upper end to the lower end on the rear surface (5a) is tilted to the vertical. Thus, the projection lens (5) has a prismatic action for directing the entire light downward. This is effective to reduce an amount of light to be shaded by a shutter (4) and provide improved brightness and novel designed appearances.

Granted: 2007-09-18
Abstract: The present invention provides a heat exchanger unit (5) that can appropriately inhibit freezing of a heat exchange element (11), even in cold-climate regions. The heat exchanger unit (5) performs heat exchange and ventilation between an indoor space (SI) and an outdoor space (SO), and is therefore provided with a heat exchange element (11), a supply air passage that is routed via the heat exchange element (11), an exhaust air passage that is routed via the heat exchange element (11), a temperature sensor (51), and a control unit. The temperature sensor (51) detects the outside air temperature. The control unit executes a first freeze inhibit control mode and a second freeze inhibit control mode. The first freeze inhibit control mode inhibits freezing of the heat exchange element (11) if the outside air temperature falls below a first level.  The second freeze inhibit control mode, which inhibits freezing more strongly than the first freeze inhibit control mode, inhibits freezing of the heat exchange element (11) if the outside air temperature falls below a second level (which is lower than the first level).

Title: Refrigeration manifold
Inventor: TERRY JAMES A
IPC: F25B41/00
Filed: 2002-01-24
Granted: 2008-07-15
Abstract: A manifold (10) for charging a system which when in use cycles a refrigerant between liquid and gaseous states is disclosed. The manifold (10) includes a housing defining a flow passage extending from an inlet (16) to an outlet (18). Structure is within the housing to define a capillary in parallel communication with a section of the passage. A refrigerant state control valve (25) is connected to the housing. The valve, when in the open position, enables concurrent refrigerant flow through both the section of the passage and the capillary to charge such a system with refrigerant in a liquid state. The valve when in the closed position sufficiently blocks the section of the passage to cause all refrigerant flow to be through the capillary thereby to enable charging such a system with refrigerant in a gaseous state.
