Patent CA-2250236-C (CA)
Inventor: OROS NICHOLAS C
IPC: G01S5/00
Filed: 1997-12-19
Granted: 2002-08-06
Abstract: Les signaux échangés entre une infrastructure fixe (110-116) et une unité mobile (160) sont l'objet de M mesures de qualité de signaux. Lesdites mesures sont ensuite mises en correspondance à l'aide de relations prédéterminées (501-503) avec les M temps de variance d'arrivée correspondants qui servent à leur tour à obtenir les variances des différentiels de temps d'arrivée M-1. Une matrice de pondération des différentiels de temps d'arrivée comprenant en partie les variances des différentiels de temps d'arrivée sert à calculer une solution par la méthode des moindres carrés pondérés (WLS) qui fournit une estimation de la position de l'unité mobile. Cette procédure peut être mise en oeuvre à l'aide d'un processeur (130) de localisation basé dans l'infrastructure fonctionnant en association avec l'unité mobile, ou par le processeur de localisation seul ou par l'unité mobile seule.

Inventor: SBASCHNIGG JOHANN
IPC: D21C9/18
Filed: 1998-11-16
Granted: 2007-02-20
Abstract: The invention refers to a process for dewatering a pulp web, particularly a chemical pulp web, where dewatering takes place between twin wire belts or felts in an initial dewatering zone with a set area pressure and then in a second dewatering zone. It is mainly characterised by the area pressure in the initial dewatering zone being pre-set, and in the second dewatering zone it is adjustable, with the web being dewatered in both directions (upwards and downwards). The invention also refers to a device for implementing the process.

Title: Extension apparatus and method
Inventor: PARK DANIEL C
IPC: B65H29/12
Filed: 1997-07-29
Granted: 2003-03-18
Abstract: The present invention relates to an apparatus and method for providing a conveying path for advancing sheet articles between sheet processing apparatuses. Conventional apparatuses for providing conveying paths of varyi ng lengths include a translatable extension table with a sliding belt/pulley arrangement. Such arrangements prevented complete abutment of the table with  the downstream sheet processing apparatus and required manual adjustment of belt tension. The present invention overcomes these disadvantages through a novel extension apparatus. The extension apparatus (10) includes a base bracket (40) with a pair of rotatably movable spring-loaded bracket arms (44 A, 44B) attached to a shaft (42) extending therethrough. A pair of bracket arms  rollers (46A, 46B, 48A, 48B) are attached to each of the bracket arms. An extension plate (30) is positioned above and slidably movable on the base bracket, and a pair of rotatable extension rollers (20A, 20B) are rotatably attached to a shaft (22) extending through the extension plate such that slidable movement of the extension plate simultaneously and identically move s the extension rollers. A pair of rear rollers (R2, R4) are utilized and are operatively aligned with an extension roller and a pair of bracket arm rollers. A pair of belts extend at least partially around and operatively engage one of the rear rollers, one of the extension rollers, and a pair of the bracket arm rollers of one of the bracket arms. The belts have an upper reach section and a lower reach section between the rear rollers and the extension rollers, and the upper reach section of the belts from a conveying  path for advancement of the sheet articles while the bracket arm rollers engage each belt in the lower reach section.

Title: Hydraulic parking brake for a railroad vehicle braking system
Inventor: ZEMYAN JAMES M
IPC: F16D65/28
Filed: 1999-12-09
Granted: 2004-11-30
Abstract: A hydraulic parking brake assembly for a railroad vehicle braking system is provided for an automatic application of the parking brake in the absence of an air source. The hydraulic parking brake assembly comprises a hydraulic actuator having a hydraulic piston and a spindle. The spindle is capable of entering a hole provided in the back surface of a pneumatic cylinder of the railroad vehicle braking system. Upon the application of hydraulic fluid within the hydraulic actuator, the hydraulic piston and spindle move in a forwardly direction, causing the spindle to contact the piston within the pneumatic cylinder and apply a force to this pneumatic piston as if pneumatic pressure were applied within the pneumatic cylinder.      Such application of force to the pneumatic piston initiates a braking sequence to achieve application of the parking brake to the railroad vehicle eliminating the need to manually apply the parking brake with a hand wheel.

Title: Multi-station dangerous condition alarm system incorporating alarm and chirp origination feature
Inventor: O'DONNELL THOMAS J
IPC: G08B29/18
Filed: 1998-07-24
Granted: 2002-04-30
Abstract: In a dangerous conditions sensing alarm system which includes a plurality of interconnected dangerous condition sensing units (Unit A, Unit B 70, Unit C  71, Unit D 72, Unit E 73), such as smoke detectors, of the general type in which each unit responds to an apparently sensed dangerous condition by issuing an audible alarm and also by transmitting, from an input/output terminal (20 - I/O), a signal to the other units (received as an external alarm signal at corresponding input/output terminals of the other units) so that an alarm condition sensed by any one of the units results in alarms being sounded by all the units, a unit initiating an alarm (which may be false) is marked by an alarm origination circuit. The alarm origination circuit includes a visual indicator such as an LED (61) and a latch device such as an SCR 51 connected in-circuit such that, when the SCR is turned "on", the LED is activated and remains lit until the SCR is turned "off". The SCR is turned "on" by a signal developed from the audio frequency drive to the unit annunciator (22) unless this action has been earlier inhibited by an electronic switch (52) which, just before the local alarm is sounded, places a virtual ground on the SCR gate (75). The electronic switch is activated by an external alarm signal more quickly than the local unit's audio frequency drive is established. Thus, an external alarm signal will not cause the LED to light at the local unit.

Abstract: Hydrogen sulfide is removed from gas streams by reaction with sulfur dioxide to produce sulfur. The reaction is effected in a reaction medium comprising a non-aqueous Lewis base with a pK b value of about 6 to about 11. The reaction medium possesses a specific combination of properties: a) absorbs sulfur dioxide and reacts chemically therewith, the reaction medium containing hydrogen sulfide, sulfur and water to form complex sulfur-oxide species, including sulfate and polythionate species, whereby the resulting solution exhibits no or an insignificant sulfur dioxide vapor pressure; b) absorbs hydrogen sulfide; c) removes the hydrogen sulfide from the gas stream through contact of the gas stream with the reaction medium in the presence of the complex sulfur-oxide species; d) acts as a catalyst for the overall reaction of the hydrogen sulfide with sulfur dioxide to produce sulfur; and (e) has the capacity to absorb sulfur dioxide in sufficient quantity to remove substantially all the hydrogen sulfide from the gas stream, notwithstanding short term variations in the stoichiometric balance between the hydrogen sulfide and the sulfur dioxide in the reaction medium. The reaction medium may be preloaded with sulfur dioxide, whereby the complex sulfur-oxide species are preformed in the reaction medium before contacting with the gas stream.

Abstract: Ce catalyseur est destiné à la production d'acétate de vinyle par réaction d'éthylène, d'oxygène et d'acide acétique. Il est constitué d'un support poreux sur les surfaces poreuses duquel sont déposées des quantités catalytiquement efficaces de palladium, d'or et de cuivre à l'état métallique. Le procédé de réalisation de ce catalyseur consiste à prendre ce support dont les surfaces poreuses contiennent des quantités catalytiquement efficaces de palladium et de cuivre métallique préalablement réduits, et à les imprégner d'une solution d'aurate de potassium. Le procédé consiste ensuite à réduire l'aurate de potassium en une quantité catalytiquement efficace d'or métallique. Une autre façon de faire est de prendre le support et de le mettre en contact d'abord avec de l'or, puis avec des complexes palladium-cuivre. Une façon de faire encore différence consiste à utiliser des réactifs exempts de sodium.
