Title: Dual function inboard barrier/bridgeplate assembly for wheelchair lifts
Inventor: DUPUY JAMES R
IPC: A61G3/06
Filed: 1999-04-30
Abstract: A dual function, inboard barrier/bridgeplate assembly for wheelchair lifts having a stowable platform, the barrier being pivotably secured to the inboard end of the lift platform, which barrier is actuated by a link to variously raise the barrier to a safety position and lower it to a bridging position in accordance with the position of the platform. The dual function barrier/bridgeplate system is particularly useful in combination with a parallelogram type lift employing an articulated lever assembly having a sliding block for leveraging the platform from a horizontal transfer orientation to a vertical, or over-vertical stowage position. There is disclosed a barrier assembly in which a spring assist system comprising a gas spring acting on one member of the articulated lever assembly and a lever arm linking a second arm of the articulated lever assembly to the barrier co-operate to actuate the barrier from a raised position when the platform is away from the transfer level and a lowered position to act as a bridge plate at the transfer level. A telescoping push arm is included which actuates the barrier by means of a pivoted link which rotates the barrier in response to the telescoping motion of the push arm. A safety interlock and load detecting system may be employed to prevent the platform from moving to the stowed position when a load greater than a predetermined weight is on the platform. An anti-free fall mechanism is disclosed comprising a pin in the slide block which engages mating slots in the telescoping push arm members to lock their length during the initial stage of deploy of the platform downwardly from the vertical stowed position.

IPC: H04J3/14
Filed: 1999-09-27
Abstract: A method and apparatus for reliably detecting both AIS and AIS-CI signals in the presence of a bit error ratio up to 1x10-3 includes an AIS detector having an AIS indication output, a CI detector having a CI indication output, and a two signal AND gate having its inputs coupled to the respective outputs of the detectors and having an output indicative of an AIS-CI detection.  The AIS detector has an adjustable zero threshold and the CI detector has a threshold output coupled to the AIS detector for adjusting the zero threshold. According to the method of the invention, the AIS detector zero threshold is normally set at the normal threshold (1x10-3) but is reset to a higher threshold (e. g., 2x10-3) when the CI detector detects the presence of the CI code word. The AIS signal is detected in a normal way and the AIS-CI signal is detected only when the CI detector detects the presence of the CI code word AND the AIS detector detects the presence of the AIS signal using the higher zero threshold. According to a preferred embodiment, the zero threshold is raised if the CI detector detects two consecutive CI code words, but the CI indication output is indicated only of the CI detector detects eight CI code words in 40ms. The zero threshold is returned to normal when the CI detector detects ten consecutive absences of the CI code word.

Abstract: A vacuum cleaner filter bag retainer includes slots on each side which receive a cardboard plate attached to a filter bag. The plate is slid into the slots of the filter bag retainer such that openings in the plate and bag match with an opening in the filter bag retainer. The retainer is attached to a tank through an opening in the tank, and an inlet fitting extends from outside the tank, through the retainer, and into the bag. The inlet fitting, therefore, prevents the bag from sliding out of the slots in the retainer. A swivel fitting loosely traps the inlet fitting adjacent the filter bag retainer through threads on the swivel fitting and the retainer. The inlet fitting also holds a hose to the inlet fitting.

Title: Hydraulic parking brake for a railroad vehicle braking system
Inventor: ZEMYAN JAMES M
IPC: F16D65/28
Filed: 1999-12-09
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.

IPC: A61F2/18
Filed: 1998-08-27
Abstract: Ce système d'électrode inclut une matrice d'électrodes (10) et un positionneur souple (20). La matrice d'électrodes (10), qui est de forme droite ou incurvée, est montée sur un support souple de façon à pouvoir s'infléchir facilement dans une cavité anatomique telle que la rampe tympanique de la cochlée de l'homme. Le positionneur souple (20) est normalement moulé en forme incurvée dans un polymère de silicones de façon à pouvoir facilement se glisser dans la cavité anatomique. Certaines réalisations peuvent également inclure un insert de guidage (30) d'électrode. Le positionneur souple (20, 20') comble le volume de la rampe tympanique de façon à forcer la matrice d'électrodes à s'appliquer contre la paroi de la columelle. Une réalisation du positionneur (20') comporte un canal (27) par lequel il est possible d'insérer amovible un stylet de fil de guidage. Un index de platine (29) peut être inclus dans l'extrémité distale du positionneur (20') de façon à favoriser l'observation de l'emplacement du positionneur sur un système d'imagerie radiographique. L'insertion de la matrice d'électrodes (10) peut se faire après ou avant l'insertion du positionneur (20). En effet, l'insertion de la matrice d'électrodes peut se faire en deux temps. Le premier temps consiste à mettre en place, à la profondeur voulue, le positionneur souple dans la rampe tympanique de façon que le positionneur vienne s'appuyer sur la paroi externe ou latérale de la rampe tympanique. Cela laisse une ouverture légèrement plus grande que la coupe de la matrice d'électrodes au voisinage de la paroi interne de la rampe tympanique. Le deuxième temps consiste à insérer la matrice d'électrodes (10) dans l'orifice défini entre le positionneur et la paroi interne. On peut, le cas échéant, se servir de l'insert de guidage pour faciliter le guidage de la matrice d'électrodes dans cet orifice. Une autre façon de procéder consiste, pour insérer la matrice d'électrode, à insérer en premier la matrice d'électrodes (10) dans la rampe tympanique, puis à insérer en second le positionneur (20) dans la rampe tympanique de façon à venir entre la matrice d'électrodes et la paroi externe de la rampe tympanique. L'insertion du positionneur dans la rampe tympanique après que la matrice d'électrode y a été partiellement introduite favorise l'introduction plus profonde de la matrice d'électrodes dans la rampe tympanique jusqu'à la position finale et à son maintien dans cette position.

Abstract: A window lift bracket for attachment to a movable window and which is connectable to a window lifting mechanism. The window lift bracket includes a base which is attachable to the window lifting mechanism and spaced apart sidewalk extending from the base being positionable on either side of the movable window. The spaced apart sidewalls define a channel therebetween.  The window lift bracket includes at least one member, such as a flexible beam member, which is disposed generally in the channel for engaging the window when the window is disposed therein. Preferably, the engagement between the member and the window provides a reduced stress area at the bottom of the channel. Opposing surfaces of the spaced apart sidewalls may provide convoluted surfaces, such as protrusions and depressions, which effectively increase the surface area to which the adhesive adheres, thereby improving the adhesion of the adhesive to the window bracket and the window.
