Abstract: Disclosed is a process for the production of an oxo alcohol having 7 to 18 C atoms by hydroformylation of the corresponding olefin with synthesis gas in the presence of an organic phase containing a cobalt catalyst at 50 to 220°C and a pressure from 100 to 400 bar, and subsequent hydrogenation of the aldehydes. The cobalt catalyst is formed by reacting an aqueous cobalt salt solution in the presence of an organic solvent which is only slightly miscible with water or not at all, with synthesis gas, and the organic phase containing the cobalt catalyst is obtained by extraction of the cobalt catalyst formed from the aqueous phase by means of an organic extractant which is only slightly miscible with water or not at all. The formation of the cobalt catalyst, the extraction of the cobalt catalyst formed into the organic phase and the hydroformylation of the corresponding olefins are carried out in a single-stage process. The oxo alcohol produced may be used for the production of a carboxylic acid ester useful as plasticizer for plastics.

Granted: 2004-08-24
Abstract: La présente invention concerne un procédé d'annulation d'écho par double filtre mettant en oeuvre une nouvelle procédure de mesure de la qualité (qa, qp) servant de base à une nouvelle technique de sélection et de transfert de filtre, la mesure de la qualité représentant l'efficacité du filtre pour l'annulation adaptative d'écho. Le procédé consiste à effectuer une mesure par corrélation entre un signal chargé d'écho et un signal d'estimation d'écho, puis à mesurer un signal résiduel résultant de la différence entre le signal d'estimation d'écho et le signal chargé d'écho. Pour calculer la mesure de qualité, le procédé consiste alors à diviser par la mesure de puissance obtenue la mesure par corrélation obtenue. Un filtre adaptatif programmable permet ensuite de mesurer et comparer la qualité de chacun des filtres du double filtre. Le meilleur des deux filtres à la mesure de qualité sert à déterminer un gabarit d'écho (570, 580) qui est transféré à l'autre filtre.

Abstract: Dans la présente invention, les fonctions de compensation de dispersion chromatique et d'affaiblissement de ligne d'une liaison à multiplexage par division des longueurs d'ondes sont exécutées par un noeud comportant une série concatenée d'éléments compensateurs de dispersion (F¿1?-F¿3?) sélectionnables par longueur d'onde et de commutateurs (S¿1?-S¿4?). Les commutateurs (S¿1?-S¿4?) servent à sélectionner ou contourner les éléments compensateurs de dispersion (F¿1?-F¿3?); si l'un d'eux (F¿1?-F¿3?) est correctement sélectionné, le canal correspondant (.lambda.¿1?-.lambda.¿3?) est compensé en dispersion et renvoyé sur un port d'atténuation (3). Tout canal restant est remis en circulation par les commutateurs (S¿1?-S¿4?) à destination des éléments compensateurs de dispersion restants (F¿1?-F¿3?) où ils subissent une compensation en dispersion puis sont renvoyés sur une sortie optique (5). Dans les exemples préférés, le noeud comporte un port d'introduction (6) pour permettre le multiplexage de canaux additionnels. Cela permet au noeud d'accomplir à la fois les fonctions d'atténuation et d'insertion en plus de la compensation de dispersion, ce qui en fait un noeud à atténuation compensatrice d'atténuation et d'insertion.

Title: Wearable camera system with viewfinder means
Inventor: MANN W STEVE G
IPC: H04N5/77
Filed: 1998-10-15
Granted: 1999-11-02
Abstract: A novel means and apparatus for a new kind of photography and videography is described. In particular, a wearable camera with a viewfinder suitable for long-term use is introduced. The system, in effect, absorbs and quantifies rays of light and processes this quantigraphic information on a small wearable computer system, then the processed information is re-constituted into light rays emerging to reconstruct the virtual image of objects at nearly the same position in space, or at a coordinate transformed position, as viewed by the wearer of the apparatus. The wearer of the apparatus becomes, after adaptation, an entity that seeks, without conscious thought or effort, an optimal point of vantage and camera orientation. Because of the wearer's ability to constantly see the world through the apparatus, which may also function as an image enhancement device, the apparatus behaves as a true extension of thewearer's mind and body, giving rise to a new genre of documentary video.

Granted: 2006-03-14
Abstract: A method of monitoring the removal by a filter medium of a target substance from a liquid passing through the filter medium. The method involves: providing an indicator means; providing a filter medium having a plurality of binding sites which have a first affinity for the target substance and a second affinity for the indicator means; introducing the indicator means into the liquid; passing the liquid through the filter medium; and determining the presence or absence of the indicator means in the liquid which has passed through the filter medium. The first and second affinities are adapted to require binding of th e indicator means by the filter medium only so long as binding sites are available to the target substance. Thus, the indicator means is adapted to compete with the target substance. As a practical matter, the liquid typically will be water. The indicator means may denote when the filter medium is not effective by altering the taste of the water passing through the filter medium. Alternatively, the indicator means may denote when the filter medium is not effective by altering the color of the water passing through the filter medium. For example, the indicator means may impart a color to the water passing through the filter medium.

Title: Canopy mounting device for exit sign
Inventor: EVARTS DAVID A
IPC: F21V21/02
Filed: 1999-07-16
Granted: 2007-06-19
Abstract: Internally illuminated emergency signs are typically placed in elevated locations which are awkward for electricians to reach, yet must be securely mounted. It is therefore difficult and time-consuming to make wiring connections after the mounting operation is completed. In order to facilitate both quick and easy wiring of the sign, and secure mounting thereof, an improved canopy features a projecting bracket which slips into a slot in a side or top of the sign housing, and engages over horizontally extending screws. Rapid, yet secure mounting of the sign is achieved by cantilevering the sign on the bracket, if side mounting is used, or by use of a locking pin, if top mounting is used. The locking pin keeps the screws from sliding laterally with respect to the bracket.
