Abstract: A fence system for table saws.  The fence system comprises a support system for supporting a fence member above a work surface of the table saw.  The fence system also includes a locking system that is independent of the support system. The locking system comprises first and second jaw members that are operated in opened and closed positions, where the jaw members grip a structural member extending from the table saw when in the closed position.  The jaw members are free to move in a vertical plane that is substantially parallel to an abutment surface on the fence member.  But the fence member engages the jaw members to prevent relative movement between the fence member and the jaw members towards and away from the saw blade.  Employing a locking system that is separate from the support system allows the support system to be designed for smooth movement and adjustability.

Title: Method and apparatus for navigating with correction of angular speed using azimuth detection sensor
Inventor: OSHIZAWA HIDEKAZU
IPC: G01C21/00
Filed: 1997-11-17
Abstract: An apparatus and method for more accurately determining the position of a moving object by using an azimuth detector distinct from an angular speed detector to correct the gain error and the offset error of the angular speed detector. The position of the moving body is determined using the offset error- and gain error-corrected angular speed. The correction of the offset error includes checking the azimuth and movement of the moving object for three predetermined periods of time; then checking whether the moving object was moving in a straight line each of the three predetermined periods of time. If the object was moving in a straight line each of the three predetermined periods of time, then an offset error correction value is computed using data from the second of the three predetermined periods of time. The correction of the gain error includes determining the movement of the moving object as straight; then determining the movement of the moving object as a turn; then determining the movement of the moving object as straight again. If the turn was a left turn, a left gain error correction value is computed. Similarly, if the turn was a right turn, a right gain error correction value is computed.

Abstract: Les fruits et les légumes déshydratés se caractérisent par une teneur en eau de 4 à 7  % et une activité de l'eau de 0,4.  En substance, les cellules des produits déshydratés ne sont pas endommagées.  Le processus de séchage à l'air est doux et comporte quatre phases, au cours desquelles la température de l'air de séchage est maintenue à 60 degrés C.  Durant la première phase, l'humidité relative de l'air de séchage peut augmenter pour atteindre 50 à 55 %, et est maintenue de façon sensiblement constante à cette valeur durant la seconde phase en conservant un échange sensiblement constant entre l'air de séchage et l'air frais.  Au cours d'une troisième phase, l'humidité relative du moyen de séchage peut diminuer assez rapidement jusqu'au début de la quatrième phase.   ce moment, l'humidité relative peut asymptotiquement s'approcher d'une valeur d'humidité relative prédéterminée.  Au cours du processus de séchage, on évite d'avoir des différences excessives de température et d'humidité relative entre le moyen de séchage et le produit, afin d'endommager le moins possible la structure cellulaire du produit.

Title: Procede et reacteur pour le traitement de combustibles presentant une large distribution granulometrique
Inventor: OKSANEN MAUNO
IPC: F23C6/04
Filed: 1996-09-30
Abstract: L'invention concerne un procédé et un réacteur pour le traitement des combustibles présentant une large distribution granulométrique, notamment du point de vue de la combustion de la flamme. Le combustible est soufflé tangentiellement au moyen d'un flux d'air dans une chambre de tourbillonement (1) qui contient une masse en combustion: il en résulte un tourbillon du centre duquel un flux de matériau est entraîné hors de ladite chambre. On fait en sorte que le tourbillon créé par l'arrivée du mélange combustible-air et que le diamètre du flux de sortie occasionnent un retard sélectif pour les particules grossières si bien que, avant de sortir de la chambre de tourbillonement, les particules subissent une réduction de taille en-deçà de la valeur limite souhaitée, au moyen d'un traitement mécanique obtenu par évaporation, pyrolyse et collision. La température de l'enveloppe cylindrique de la chambre de tourbillonement (1) est maintenue au-dessous du point de fusion de la cendre.
Patent CA-2232712-A1 (CA)
Inventor: GOFF STEPHEN ARTHUR
IPC: C07K14/705
Filed: 1996-09-27
Abstract: The present invention is drawn to a method of controlling gene expression in plants. Specifically, the method comprises transforming a plant with a USP  receptor expression cassette which encodes a USP receptor and at least one target expression cassette which encodes a target polypeptide. Contacting said transformed plant with juvenile hormone or one of its agonists activates expression of the target polypeptide in the presence of said USP receptor polypeptide. Optionally, additional "secondary" receptor expression cassettes may be used, wherein the secondary receptor expression cassette encodes a receptor polypetide distinct from USP. The method is useful for controlling various traits of agronomic importance, such as plant fertility. Also disclosed is a method of identifying previously unknown ligands for USP.  Substances to be tested are identified by placing them in contact with plant cells transformed with a USP receptor expression cassette and a target expression cassette. The target expression cassette encodes a reporter polypeptide whose expression can be determined quantitatively or qualitatively, whereby the test substance is identified as a ligand for USP.

Title: Processor independent error checking arrangement
Inventor: MOHAT WILLIAM D
IPC: G06F11/16
Filed: 1996-12-12
Abstract: A dual processor computer system with error checking that stops immediately when a discrepancy is detected between the two processors. The system includes a first processing system (20) for executing a series of instructions including input/output instructions.      A second processor (30) executes the same instructions independently of and in synchronization with the first processing system. All significant processor address, data, and control signals are connected to all peripheral devices by a processor independent I/O bus (10). A comparison circuit (9) which detects discrepancies in the operation of the two lock step processing systems is connected between the processors and the processor independent I/O bus. The comparison circuit provides a signal that immediately stops operation of the processors when an error is detected. The I/O bus is independent of the processor type, clock rate, and peripherals chosen in the construction of the computing system. This independence allows the computing system to be upgraded with faster processors and newer peripherals, without having to redesign the computing platform and the error checking circuit.
