Patent CA-2379567-C (CA)
Title: Heterogeneous epoxidation catalyst
Inventor: MORALES EDRICK
IPC: B01J31/38
Filed: 2000-08-08
Granted: 2008-10-28
Abstract: Highly active and selective epoxidation catalysts are prepared by combining high surface area silica support or the like, having surface area greater than 1100 m2/g, with a titanium source. The titanium source is a non-oxygenated hydrocarbon solution of a titanium halide or a vapor stream of titanium tetrachloride. The impregnated support is then calcined at an elevated temperature (preferably, in a substantially oxygen-free atmosphere), and, optionally, reacted with water and/or silylated. The resulting materials are highly active heterogeneous epoxidation catalysts for the reaction of olefins with organic hydroperoxides.

Abstract: De la vapeur d'eau est introduite dans un courant d'air d'admission (16) d'un moteur, par exemple par un processus de pervaporation à travers une membrane hydrophile non poreuse (18). Un réservoir d'eau (20) qui peut contenir de l'eau contaminée, crée un gradient de pression de vapeur à travers la membrane hydrophile (18) jusque dans le courant d'air d'admission (16), pendant que le débit d'amenée de la vapeur d'eau dans un cylindre (38, 40) est autorégulé par le débit d'air traversant la membrane. La membrane hydrophile (18) filtre par conséquent également l'eau provenant du réservoir d'eau (20) à un point tel que de la vapeur d'eau pure est fournie au courant d'air d'admission (16). L'amenée de vapeur d'eau peut néanmoins être régulée à l'aide d'un capot (26) qui coulisse sur la membrane hydrophile pour limiter sa surface exposée. Dans une variante, de la vapeur d'eau est introduite dans un ou plusieurs flux de gaz d'une pile à combustible, par séparation du flux de gaz provenant du flux de gaz d'échappement humide, au moyen d'une membrane hydrophile, laissant ainsi passer l'humidité à travers la membrane pour humidifier le flux de gaz et empêchant ainsi le dessèchement de la membrane d'échange de protons.

Title: Method and installation for hot dip galvanizing hot rolled steel strip
Inventor: REIFFERSCHEID MARKUS
IPC: C23C2/40
Filed: 2000-08-04
Granted: 2009-02-03
Abstract: The invention relates to a method for hot dip galvanizing hot rolled steel strip and to a hot rolled strip galvanizing installation. In a first method step, the strip (50) to be galvanized is introduced into a pickling station (10) inside of which the layer of scale as well as reaction products are removed from the surface of the strip.  In a subsequent working step, the strip (50) is introduced into a rinsing station (20) in which residual pickle and pickle products are removed from the surface of the strip. Afterwards, the strip (50) is introduced into a drying station (30) and dried therein. From there, the strip (50) is introduced, in another method step, into a furnace (40) in which it is heated, under a protective gas atmosphere, up to a galvanizing temperature. In a final method step, the strip is guided through a galvanizing bath in which it is coated with a hot dip galvanizing layer. This method is improved in such a way that the strip (50) is heated in the furnace (40) to a temperature that does not exceed the bath dipping temperature in the zinc bath by more than 50 °K.

Abstract: L'invention concerne un panneau de fibres (4), présentant des zones de rupture (30), obtenu par formage à sec d'un tissu fibreux (2) placé dans une boîte de formage (6) et par traitement thermique dans un four, les fibres étant sélectionnées parmi des fibres synthétiques, des fibres naturelles ou un mélange de celles-ci. L'invention concerne aussi une boîte de formage (6) utilisée dans la fabrication de panneaux de fibres (4) et disposée au-dessus d'une table de formage (14) traversant la boîte sous vide (20). L'invention vise à ménager des zones de rupture (30) dans les panneaux de fibres (4) formés directement lors du processus de formage et à obtenir un espace (36) de zone de rupture sans avoir à faire appel à des outils de coupe. Ainsi, les panneaux de fibres (4) s'adaptent facilement en largeur et longueur sans recourir à des outils. La séparation du panneau de fibres (4) offre en outre une face de rupture régulière garantissant qu'aucun pont thermique ne se forme au niveau des jointures. La boîte de formage (6) peut être dotée de cloisons verticales (12) s'étendant le long de la plaque de formage (4) et d'ensembles de cloisons verticales (13) s'étendant transversalement par rapport à la plaque de formage (14). Ces cloisons (12, 13) sont supposées permettre la fabrication de panneaux de fibres (4) à zones de rupture (30) ou de panneaux de fibres (4) en bandes/sections indépendantes (58, 60).

Title: Aircraft landing gear with highly offset strut pivot axis
Inventor: DERRIEN MICHEL
IPC: B64C25/10

Granted: 2005-08-09
Abstract: The invention concerns an aircraft landing gear, comprising a strut (11) consisting of a strut assembly (12) wherein slides a telescopic rod (13) with axis (Z), said strut assembly being articulated on an aircraft structure capable of pivoting about an axis (X) highly offset relative to the sliding axis (Z).

Abstract: The present invention provides for automatic placement of typographical features such as vertical stems or horizontal segments of a character (205) on high contrast pixel sub-component boundaries as part of a rendering process that uses separately controllable pixel sub-components (202, 203, 204) of pixels to represent different portions of the character (205). In order to identify the typographical features of the character (205) that are to be aligned with high contrast pixel sub-component boundaries, topology of the character is analyzed at runtime. In display devices having vertical stripes of same-colored pixel sub-components (202, 203, 204), it has been found that character legibility is increased when the left edges of stems (206) are aligned with high contrast boundaries (208) between pixel sub-components.  Processing time and resources are conserved by performing a partial, rather than a full, topological analysis of the character. For example, some font files include data structures that define the position of key control points associated with the character, thereby indicating where the stems or other typographical features are located, and the relationship between different typographical features.

Granted: 2012-10-23
Abstract: A satellite radiotelephone frequency (fU,fD) can be reused terrestrially by an ancillary terrestrial network (Fig.1) even within the same satellite cell, using interference cancellation techniques. Moreover, the ancillary network can use a modified range of satellite band forward link frequencies (f'D) for transmission, to reduce interference with out-of-band receivers. A modified range of satellite band forward link frequencies that is used by the ancillary terrestrial network can include only a subset of the standard satellite band forward link frequencies to provide a guard band, can include power levels that monotonically decrease as a function of increasing frequency and/or can include two or more contiguous slots per frame that are left unoccupied and/or are transmitted at reduced maximum power. Time division duplex operation of the ancillary terrestrial network may also be provided over at least a portion of satellite band return frequencies.
