Patent CA-2384753-A1 (CA)
Inventor: DELZER GARY A
IPC: B01J23/66
Filed: 2000-09-13
Abstract: L'invention concerne une composition de catalyseur que l'on peut utiliser pour hydrogéner un hydrocarbure fortement insaturé, par exemple un alcyne ou un dioléfine. La composition de catalyseur contient du palladium, un composant catalyseur soit d'argent soit d'un composé métallique alcalin, ou les deux, et un support de catalyseur d'aluminate de métal. Ledit support est préparé suivant un procédé qui consiste à incorporer de l'alumine avec un composant métallique, à imprégner, de préférence, l'alumine avec un composant de métal fondu, pour produire une alumine de métal, puis séchage et calcination à haute température pour produire un support de catalyseur d'aluminate de métal. La composition de catalyseur peut servir à hydrogéner un hydrocarbure fortement insaturé en hydrocarbure moins insaturé. Le procédé implique la mise en contact d'un hydrocarbure fortement insaturé avec une composition de catalyseur en présence d'hydrogène dans des conditions d'hydrogénation suffisantes pour hydrogéner ledit hydrocarbure fortement insaturé.

Abstract: A mower blade with a trailing sweeping edge that projects below the cutting edge serves to brush cut particles deposited on the grass surface down between the grass blades and up into the air stream within the mower deck. As the cut particles are recirculated in the air stream, they are recut in a mulching action. The particles forced down between the grass blades reduce the amount of cut grass that has to be discharged. As a result, the amount of cut grass particles left on the lawn is reduced, thereby providing an improved appearance.

Title: Reconfiguration optical add-drop multiplexers
Inventor: GARRETT MARK H
IPC: H04B10/296
Filed: 2002-03-14
Abstract: This invention provides a novel wavelength-separating-routing (WSR) apparatus that uses a diffraction grating (101) to separate a multi-wavelength optical signal by wavelength into multiple spectral channels, which are than focused onto an array of corresponding channel micromirrors (220). The channel micromirrors are individually controllable and continuously pivotable to reflect the spectral channels into multiple output ports. As such, the inventive WSR apparatus is capable of routing the spectral channels on a channel-by-channel basis and coupling any spectral channel into any one of the output ports. The WSR apparatus of the present invention may be further equipped with servo-control and spectral power-management capabilities, thereby maintaining the coupling efficiencies of the spectral channels into the output ports at desired values. The WSR apparatus of the present invention can be used to construct a novel class of dynamically reconfigurable optical add-drop multiplexers (OADMs) for wavelength division multiplexing (WDM) optical networking applications.
