IPC: C07C67/327
Filed: 1996-12-06
Abstract: An improved process for producing n-butyl acrylate in high yield and high purity substantially free of acrylic acid, incorporates one or more of the following new process components in an acid-catalyzed esterification process for producing n-butyl acrylate:      1. A hydrolytic recovery component, wherein heavy end adducts produced during the acid-catalyzed esterification are hydrolyzed, recovered, andrecycled as valuable reactants from a hydrolytic recovery unit (HRU); 2. A cracking reactor component, preferably used with the HRU, wherein additional valuable reactants are recovered and recycled after treatment in the cracking reactor; and 3. A new distillative component, wherein a crude n-butyl acrylate stream is efficiently distilled in an aqueous mode through an acrylic acid separation column, thereby providing n-butyl acrylate substantially free of acrylic acid and in high yield. The first two components also are applicable to acid-catalyzed processes producing C1 to C4 alkyl acrylates.

Abstract: La présente invention concerne un agent destiné à extraire les contaminants de l'eau utilisée dans la fabrication du papier et de produits connexes, de la formule générale (ZO)¿n?Al¿n?(OH)¿n-m?Cl¿m? (ou d'une formule empirique très proche de celle-ci), dans laquelle Z est dérivé d'une matière d'alumino-silicate, ledit agent ayant été éventuellement recouvert de polymère. L'agent est préparé de la façon suivante: on active la matière d'alumino-silicate en la traitant avec de l'acide ou en la soumettant à un échange d'ions ammonium, et on chauffe ensuite la matière ainsi activée en présence d'un agent cationique, pour la revêtir d'un polymère. L'alumino-silicate préféré est un minéral contenant de la zéolite d'une structure de clinoptilolite et l'agent cationique préféré est sélectionné parmi un polyaluminiumchlorure, une épichlorhydrine (ou un dérivatif polymère de celle-ci) ou un dicyanodiamide. Le polymère de revêtement préféré est un polyacrylamide. L'utilisation de cet agent entraîne une augmentation de la production et une réduction à la fois de la formation de boues, de la charge de contaminants, des besoins en oxygène chimique, ce qui est source d'économies.

Patent CA-2208804-A1 (CA)
Inventor: LAURENCE MICHEL
IPC: H04L12/54
Filed: 1997-06-24
Abstract: A method of controlling the supply of cells into an asynchronous network, comprises the steps of storing incoming bytes from multiple channels in respective channel buffers, creating in memory a timing event wheel partitioned into a plurality of sectors, of which one is active at any time, and placing cell pointers in the sectors. The cell pointers identify channel buffers and are distributed around the wheel in accordance with a desired transmission schedule. The wheel is stepwise advanced at a predetermined rate, and the cell pointers in the active sector are scanned at each advance of the wheel to identify the corresponding channel buffers. The bytes from the identified channel buffers are assembled into cells, which are forwarded for transmission over the asynchronous network. These are then multiplexed with VBR cells from another source.

Patent CA-2223144-A1 (CA)
Inventor: EVANS ROBERT W
IPC: E21B31/113
Filed: 1996-06-03
Abstract: A mechanical-hydraulic double-acting drilling jar includes an inner tubular mandrel (12)telescopingly supported inside an outer tubular housing (14). The mandrel and the housing each consist of a plurality of tubular segments joined together, preferably by threaded inner connections. Upper (134) and lower (166) pressure pistons are slidably disposed within the housing, respectively closing upper and lower substantially sealed hydraulic chambers (132,164). Longitudinal movement of the mandrel engages the collet (184), which in tum, translates either the upper piston (134) or the lower piston (166), depending on the direction of mandrel movement. As one of the pistons is moved, fluid pressure builds in the associated hydraulic chamber, retarding further movement of the mandrel, enabling potential energy to build in the drill string. The collet is restricted from expanding until the mandrel reaches a particular point in the housing, at which time the collet expands, releasing the mandrel to rapidly collide a hammer surface (32,21) thereon with an anvil surface (44,41) in the housing.

Inventor: S LVE TORBJOERN W
IPC: G10L21/0232
Filed: 1996-09-13
Abstract: A method and system are provided for adaptively reducing noise in frames of digitized audio signals that include both speech and background noise. Frames of digitized audio signals are passed through an adjustable, high-pass filter circuit to filter a portion of background noise located in a low frequency range of the digitized signal. The filter circuit is adjusted by a filter control circuit adapted for a current frame to exhibit a selected frequency response curve. The filter control circuit includes a speech detector for detecting the presence or absence of speech in the frames of digitized audio signals. The filter circuit is adjusted when no speech is detected in the current frame. In a first preferred embodiment, the filter control circuit controls the filter circuit by calculating a noise estimate corresponding to the background noise, and adjusting the filter circuit based on the noise estimate. As the noise estimates increase, the filter circuit is adjusted to extract increasing amounts of energy falling in low frequency ranges of speech. In a second preferred embodiment, the filter circuit is adjusted as a function of a noise profile estimate. A noise profile estimate for a current frame is determined as a function of speech detection and is compared to a reference noise profile. Based on this comparison, the filter circuit is adaptively adjusted.
