Title: Methods for improved rheological control in cementitious systems
Inventor: PHYFFEROEN ALAIN
IPC: C09K8/514
Filed: 1996-12-13
Abstract: A microbial polysaccharide having the features characteristic of S-657 effectively improves the rheological properties of a variety of cementitious systems. The addition of S-657 to such cementitious systems as portland cement, self-leveling grouts, fresh or saltwater oil well cement slurries, microfine cements, gives rise to substantial improvements in such properties as bleed, flow resistance, fluid loss control, and the like. In addition, S-657 provides a number of advantages, including improved free water and sedimentation control, reduced fines loss during underwater placement, enhanced stability of highly diluted microfine cementitious systems, enhanced flow and workability of superworkable and self-leveling pastes, enhanced color delivery in pigmented concrete and stabilized bubble entrapment in foamed or cellular cement systems. In sprayable cementitious systems, S-657 reduces rebound and sag.

Title: Digital television receiver with adaptive filter circuitry for suppressing ntsc co-channel interference
Inventor: LIMBERG ALLEN LEROY
IPC: H04N5/44
Filed: 1998-06-19
Abstract: Co-channel interference accompanying multiple-level symbols in a digital receiver, such as a digital television receiver, is suppressed by using a first comb filter to reduce the energy of the co-channel interference before data slicing. The first comb filter incidentally precodes the symbol decoding results generated by the data slicing. A second comb filter postcodes the precoded symbol decoding results from the data slicing to generate corrected symbol decoding results. The symbol precoding of the input symbol stream results from differential delay and first linear combination of the differentially delayed terms. The postcoding of the symbol stream recovered by data slicing results from second linear combination of the symbol stream with delayed result of the second linear combination, and is performed in accordance with a modular arithmetic. One of the first and second linear combinations is subtractive, and the other is additive. The results of the second linear combination are the corrected symbol decoding results.

Abstract: La présente invention concerne un procédé et un équipement permettant à un demandeur d'entrer en contact avec un demandé grâce à un appel en PCV, que le poste appelé réponde ou soit occupé, ou non. Quand le demandeur compose un code d'accès au PCV, l'appel est dirigé vers une plate-forme de messagerie qui collecte les informations sur cet appel et tente d'établir la communication. S'il n'y a pas de réponse ou que le poste appelé soit occupé, la plate-forme de messagerie conserve le contrôle de l'appel et invite automatiquement le demandeur à donner un nom et un message qui seront indiqués au demandé. Après que le nom et le message ont été introduits, le demandeur reçoit, s'il le désire, un numéro de confirmation qui lui permet de savoir si son correspondant a reçu le message. La plate-forme de messagerie essaie de façon répétée de délivrer le message en appelant le demandé. Lorsqu'il est répondu à l'appel, elle identifie le demandeur et invite le demandé à accepter ou refuser le message en PCV. Si le demandé accepte le message, la plate-forme de messagerie en exécute la lecture et il est facturé au demandé.

Title: Air brake stroke adjustment monitoring apparatus and method
Inventor: SELLIN WILHELM KARL
IPC: F16D66/02
Filed: 1998-07-31
Abstract: The invention provides an electrical switch for monitoring stroke adjustment of an air brake as used on heavy wheeled vehicles. The switch has a switch body securable to fixed structure of the air brake, and fixed and moveable electrical switch contacts in which the fixed switch contact is fixed relative to the switch body. A switch actuator moves relative to the body and carries the moveable switch contact into and out of engagement with the fixed switch contact. The switch actuator is selectively responsive to movement of brake mechanism associated with the air brake actuation. A resilient member cooperates with the switch actuator and the body to close the switch contacts. The switch actuator passes through an opening in an air chamber of the brake and, when the brake is properly adjusted, is clear of a diaphragm plate within the chamber. As the brake is used, brake stroke adjustment eventually exceeds acceptable limits and the diaphragm plate contacts the switch actuator which is moved to open the contacts to actuate a monitor to warn the vehicle operator. The switch is fitted to an existing brake chamber using fasteners passing through openings in the chamber, or can be fitted adjacent the chamber using a bracket secured to existing fasteners.

Inventor: MORIN JEAN CHARLES
IPC: E05B73/00
Filed: 1998-08-26
Abstract: A security device for laptop- or notebook-type portable computers is provided for the securing of such a computer to a surface. The device comprises, in general, a base which is securable to the surface; a housing pivotally connected to the base for providing an enclosed space to prevent the device from being removed from the surface; and a retainer articulated from the base which is lockingly engageable with the computer to trap the computer against the surface and, hence, prevent its removal. The device is adapted to quickly engage and disengage the computer and to provide a minimum of inconvenience with respect to the task of locking and unlocking the computer. When not in use, the device moves substantially out of the way so as to minimize obstruction of the surface on which the device is employed. The device not only presents a visible deterrent, but it also presents an evident and significant physical challenge for its defeat. The invention also provides for mounting the security device to a mini-table which is sized so as to be unable to be concealed easily under garments, coats, etc., or to fit within most briefcases or the like, thereby foiling the snatch, grab and hide techniques of most laptop thieves.

Patent CA-2252794-A1 (CA)
Inventor: ROLLO PETER ERIC
IPC: F04D29/30
Filed: 1997-05-07
Abstract: An impeller (10) having an axis (12) about which the impeller is rotatable in a working direction of rotation A. A plurality of aerofoil blades (14) are spaced from and arranged about the axis (12). The inwardly axis-facing surface (16) of each blade (14) defines a longer fluid flow path across the blade than the opposite outwardly-facing surface (18). Each blade has an angle of attack from 0~ up to a positive angle of attack less than that at which the blade will induce turbulent fluid flow when the impeller is rotated in a fluid at a working speed in the working direction of rotation A. During such rotation the impeller induces an inlet fluid flow generally axially toward the impeller and an outward fluid flow away from the impeller in directions generally inclined about 30~ or more or less relative to axis (12).

Title: Procede et dispositif destines a detecter un arret de sonnerie
Inventor: BOKINGE BO
IPC: H04M3/02
Filed: 1997-11-18
Abstract: L'invention concerne un détecteur d'arrêt de sonnerie comportant un compteur de référence destiné à commander un générateur de courant à pile, qui forme le signal de sonnerie; un détecteur de passage à zéro destiné à détecter des passages à zéro dans un signal de tension à un noeud, ledit signal étant proportionnel au courant de la ligne téléphonique; et deux autres compteurs. Les passages à zéro de la tension créent une impulsion aux passages à zéro positif et négatif du détecteur de passage à zéro. Le compteur de référence est raccordé à une mémoire lorsque ces impulsions se produisent. Les passages à zéro du cycle de sonnerie précédent et du cycle de sonnerie présent sont stockés dans la mémoire. Un compteur détermine la différence entre le passage à zéro du cycle de sonnerie précédent et celui du cycle de sonnerie présent. Si la différence du passage à zéro entre le cycle de sonnerie précédent et le cycle de sonnerie présent est supérieure à une valeur fixée, le signal de sortie indique une "différence de phase", et s'il est inférieur à la valeur fixée, le signal de sortie indiquera "aucune différence de phase". Un autre compteur permet de compter un nombre préétabli de cycles de sonnerie successifs ne présentant "aucune différence de phase" au début d'un signal de salve de sonnerie, et après établissement du signal de salve de sonnerie, une autre nombre préétabli de cycles de sonneries successifs avec "différence de phase" est compté en vue de détecter l'arrêt de sonnerie.
