Title: Active feedback control system for transient narrow-band disturbance rejection over a wide spectral range
Inventor: SHOURESHI RAHMAT A
IPC: G10K11/178
Filed: 1997-06-03
Abstract: A control system provides active attenuation of excitations to a region or structure (1). A feedback sensor (14) generates a signal in response to excitations of the region (1) which is fed to a narrow-band feedback controller (5) having a frequency detector (4), a bandpass filter (6) controlled by the frequency detector (4), and a feedback control generator (8). The frequency detector (4) determines the peak frequency of the excitations. A bandpass filter (6) passes only those signals from the feedback sensor (14) in a narrow frequency band adjustably controlled by the frequency detector (4). The feedback control generator (8) receives the filtered signal from the bandpass filter (6) and produces a control output used by an actuator (13) to attenuate the excitations. Several bandpass filters (6) can be used in parallel to attenuate several frequency bands if the excitation source has a plurality of peaks. This configuration allows the bands to move across the frequency spectrum in response to the excitations.

Title: Reglazable window
Inventor: MCMANUS ARMAND
IPC: E06B3/58
Filed: 1999-01-14
Abstract: A generally rectangular reglazable vehicle window comprising a window panel of two spaced frames with an edge seal around the periphery of the panel; an egress frame in which the window panel is mounted; and a backframe defining the opening in a vehicle wall, the egress frame being hinged along an upper side on the upper side of the backframe to swing outwardly when released by an egress handle. The window panel is mounted in the egress frame between a fixed abutment rim blocking inward movement of the panel, and a removable abutment rim that is formed integrally with a retainer ring extending around the egress frame between the panel and the backframe. The ring is wedge-shaped in cross-sections for ease of insertion and removal.      Screws threaded into the retainer ring from the periphery of the egress frame normally hold the ring and the removable rim in place, the heads of the screws being recessed into the edge of the egress frame so as to be covered when the frame is in the closed position and accessible for service and repair when the frame is in the open position. A removable seal conceals the screws in the open position. The hinge for the egress frame constitutes two interfitting channels that suspend the egress frame from the top of the backframe and remain engaged as the egress frame swings open to at least a horizontal position, then disengaging to release the egress frame. A lower hinge element covers the top of the retainer rim. In a modified embodiment, a sacrificial panel covers the inner side of the window panel and is overlapped by an offset edge portion of the fixed rim.

Patent CA-2269637-A1 (CA)
Inventor: FRIESEN RICHARD
IPC: C07K5/08
Filed: 1997-11-03
Abstract: L'invention concerne de nouveaux ligands utilisés dans un dosage pour liaison de protéases et de phosphatases, qui contiennent de la cystéine à leurs sites de fixation, ou en tant que composant structural nécessaire à une liaison enzymatique. Le groupe sulfhydryle de la cystéine constitue le groupe nucléophile dans les propriétés protéolytiques et hydrolytiques du mécanisme de l'enzyme. Ce dosage peut être utilisé pour déterminer la capacité de nouveaux ligands et mélanges inconnus de composants à se lier de façon compétitive à une enzyme, en comparaison avec un agent liant connu de l'enzyme, par ex. un inhibiteur connu de l'enzyme. L'utilisation d'une forme mutante de l'enzyme naturelle ou native de type sauvage, dans laquelle la sérine, ou un autre acide aminé, par ex. l'alanine, remplace la cystéine, permet de surmonter le problème d'une interférence causée par des agents étrangers oxydants et alkylants dans la procédure de dosage. Cette interférence apparaît à cause de l'oxydation ou de l'alkylation du sulfhydryle, -SH (ou-S?-¿), dans la cystéine, qui affecte ensuite de manière défavorable la capacité de liaison de l'enzyme. L'invention concerne spécifiquement un dosage destiné à des tyrosine phosphatases et des cystéine protéases, y compris des capsases et des cathepsines, par ex. la cathepsine K(O2), ledit dosage étant réalisé par une technique de dosage de proximité à scintillation. Ce dosage a des applications importantes dans la découverte de composés destinés au traitement et à l'étude, par exemple, du diabète, de l'immunodépression, du cancer, de la maladie d'Alzheimer et de l'ostéoporose. La nouvelle caractéristique que présente l'utilisation d'une enzyme mutante peut être étendue à son utilisation dans une large gamme de dosages classiques, tels des dosages par colorimétrie, photométrie ou spectrophotométrie, des radio-immuno et des dosages par liaison compétitive à des ligands.

Inventor: MOSHER DAVID C
IPC: E02D35/00
Filed: 1999-04-23
Abstract: An attachment for skid steer loaders and small type farm tractors. This attachment is for driving round posts into the ground. It has large coil springs. Attached to these springs is a hammer. The springs are compressed by a hydraulic cylinder on this attachment. The coil springs are completely released by a hold and release mechanism. This attachment has a means of protecting the top of a round or square post from splitting and cracking by the hammer, because the hammer does not come into direct contact with the post. Instead, the hammer hits a post centering piston which is a functioning part of this attachment. The post centering piston is in direct contact with the post as it is pounded into the ground.      The post centering piston is a vertical sliding sleeve inside of the-post positioning tube. The post contact surface on the post centering position has a graduated incline to center.      When the attachment is placed over the post, the post will move to the highest position of the graduated incline, which is center. When the hammer is released the edges of the post top are forced to the center of the post all around, which will stop the post from splitting and cracking. This and other features will become clearer in the specification and drawings.

Abstract: A process for selectively extracting a value metal from a ferrous solid, the value metal being selected from the group consisting of cobalt, nickel and copper, and the ferrous solid being selected from mattes and alloys containing iron and the value metal in metallic form. In a first leach step, an aqueous solution is provided in contact with an oxygen-containing atmosphere, the first aqueous solution having a pH of less than about 2.0 and containing sufficient sulfate ion to form a soluble sulfate with the value metal contained in the ferrous solid.  The ferrous solid is added to the first aqueous solution over a period of at least one hour to increase the pH to the range of about 4 to 6, while maintaining the temperature of the first aqueous solution at less than about 100°C during addition of at least the last fifty percent of the solid. At the end of the first leach, a solid/liquid separation is performed to separate; a first liquid fraction containing soluble sulfates of the value metal from a solid iron-containing residue. The solid residue is preferably treated in a second leach step to recover copper and unleached cobalt. The second leach step comprises treating the solid residue with an acidic aqueous solution at elevated pressure and a temperature of about 120 to 220°C, to thereby oxidize copper sulfides present in the residue and cause copper to enter the liquid phase as soluble copper salts.
