Title: Spring loaded mud flap installation tool
Inventor: O'KANE DONALD L
IPC: B62D25/16
Filed: 2001-06-08
Abstract: A spring loaded mud flap tool (10) includes a hook element (20) carried by one a first of a drive rod (30). The hook end of the hook element is sized to grasp the end of the spring carried within the hanger tube of the mud flap assembly. A handle assembly (80) is carried by a second end of the drive rod. The handle assembly allows the user to manipulate the hook until it successfully grasps the spring. A bearing assembly (40) is carried on the threaded surface of the drive rod (30), and supports a pair of diametrically opposed crank handles (70). In operation, the bearing assembly rests on the open end of the hanger tube. Revolution of the crank handles turns the drive rod, which retracts the hook element and therefore retracts the spring. The force of the spring pulling the tool (10) into the hanger tube is offset by an equal force exerted by the bearing assembly on the rim of the hanger tube. A safety chain (90) connects the hanger tube and the bearing assembly.

Title: Valve and assembly for axially movable members
Inventor: ROORDA OENE
IPC: F16K15/02
Filed: 2001-06-07
Abstract: The fluid flow check valve uses a flexure plate or plates to accommodate the valve disk's axial motion required to open and close the valve. The flexure plate also limits the disk's motion in any lateral direction, so the valve disk will align properly with the valve seat and seal when it closes. The flexure plate is a flat, axial spring, made by cutting or otherwise manufacturing spiral cuts in a round, sheet metal disk. Valve qualities such as closing force, size and rigidity to lateral disk motion can be modified by varying the number and configuration of the plates, and by modifying plate characteristics. The compactness of the flexural plate design allows for a shorter valve length and cost as well as increased opportunity for flow optimisation.

Abstract: Image sensors, processors, and control systems facilitate automatic sensor operated bathroom fixtures, systems for controlling bathroom fixtures, and methods of bath-room fixture design, control, and management, as well as the control and manage-ment of hygiene and water resources. The networked plumbing systems also help facility managers and law enforcement personnel monitor the operation of various bathrooms in a facility or at remote facilities. Image sensors are used for controlling several showers, faucets, urinals, or water closets in large bathroom complexes. Im-age based intelligent bathroom fixtures and systems help enhance the privacy of users by ensuring that law abiding users need not be disturbed by police foot patrols into the restroom areas, or by security guards entering simply to make inspections.  An aquionics bathroom control system of the invention maintains the cleanliness, safety, security. and privacy of the occupants in a smart bathroom environment.  Addition-ally, in some embodiments, a bathroom facility of the invention may be used for mass decontamination during times of emergency for processing victims of a nuclear, biological, or chemical incident. Once ubiquitously installed for routine control of fixtures, the apparatus facilitates a secondary usage such as monitoring of by triage staff, medical personnel, decontamination officers, or law enforcement officers during times of terrorist consequence management.

IPC: A61N7/02
Filed: 2000-03-17
Abstract: L'invention concerne un ensemble cathéter médical à ballonnet comprenant un ballonnet comportant une zone perméable et une zone non perméable. Le ballonnet est obtenu, du moins en partie, à partir d'un tube perméable au fluide de manière que la zone perméable soit constituée d'une matière poreuse permettant à un certain volume de fluide sous pression de passer d'une chambre formée par le ballonnet à la zone perméable, en quantité suffisante pour que le fluide puisse être couplé de façon ablative aux tissus en contact avec la zone perméable. La zone non perméable est conçue pour empêcher sensiblement le fluide sous pression de passer de la chambre précitée à l'extérieur du ballonnet. Des vides peuvent être créés par expansion d'un fluoropolymère. La matière poreuse s'étend le long des zones perméable et non perméable. Selon un mode de réalisation, la matière est poreuse le long de la zone perméable et non poreuse le long de la zone non perméable, ce que l'on obtient par expansion de la zone perméable uniquement. Les pores peuvent également être formés le long des sections perméable et non perméable mais ils sont sensiblement bouchés par une matière isolante trempée, déposée ou extrudée le long de la section imperméable afin d'empêcher tout passage du fluide. La matière isolante peut, selon un mode de réalisation, être réalisée selon plusieurs formes à la surface du ballonnet.
