Title: Pot catalytique pour tubulure arriere d'echappement a detendeur de contre-pression
Inventor: TIMKO MARK
IPC: F01N13/18
Filed: 1997-03-18
Abstract: La présente invention concerne un pot catalytique (1030) pour tubulure arrière d'échappement (22), réduisant encore plus les émissions de gaz d'échappement des véhicules par les systèmes d'émission de gaz d'échappement (10). Cette invention est conforme aux dispositions légales et administratives locales ou nationales les plus exigeantes concernant les gaz d'échappement. Ce pot catalytique (1030) pour tubulure arrière comporte une enveloppe en céramique ou en acier (32). Les dimensions de cette enveloppe sont relativement faibles, soit un diamètre compris entre 1/2 pouce et 8 pouces pour une longueur compris entre 3/4 pouce et 11 pouces. Le noyau à structure matricielle (34) contenu dans cette enveloppe (32) est fait de couches de matériau catalytique qui réagissent avec les polluants de gaz d'échappement et notamment les NO¿x?, NMHC, HC et CO. Ces polluants subissent ensuite une oxydoréduction au niveau du pot catalytique (1030) de tubulure arrière (22) provoquée par les catalyseurs conventionnels tels que notamment le platine, le palladium, le rhodium contenus dans les couches nid d'abeille ou maillées du noyau à structure matricielle (34). Ce pot catalytique (1030) de tubulure arrière est maintenu en place au moyen de dispositifs ad-hoc (38), notamment des pinces, des vis de montage et des colliers de serrage. Le pot catalytique de tubulure arrière comporte également un détendeur (1050') de contre-pression. Enfin, ce pot catalytique de tubulure arrière convient également à d'autres types de véhicules tels que les camions, les motocycles ou à d'autres moteurs à compression de gaz, par exemple, ceux des tondeuses à gazon.

Title: Brake operational control
Inventor: PANGBORN DONALD R
IPC: A47B17/02
Filed: 1999-03-23
Abstract: A height adjustable mechanism for supporting a work support for vertical movement relative to a base includes a counterbalance mechanism for providing a force opposing a downward force tending to lower the work support; a lock mechanism for releasably retaining the work; support in a desired vertical position; ant a manual operator for selectively releasing the lock mechanism to permit vertical movement of the work surface, while preventing operation of the lock mechanism if the counterbalance force and the downward force are out of balance by some given extent. In the preferred construction, the lock mechanism is pivotally supported by a pin normally supported for axial sliding movement under the control of they manual operator, and the lock mechanism applies loading to the pin, when the counterbalance force substantially differs from the downward force, sufficient to constrain the pin against sliding movement, and thereby prevent release of the lock mechanism by the manual operator.

Title: Apparatus and method for tray valve attachment
Inventor: CHUANG KARL T
IPC: B01D3/18
Filed: 1998-10-09
Abstract: An apparatus and method for attaching a dispersion valve to a fractionation tray surface. The valve is inserted into a fractionation tray perforation. At least two legs extend downward from a cover plate with a larger square area than the perforation. Each of the legs is positioned at or near the peripheral inner surface of the tray perforation. Each leg has an outwardly projecting hooking element. As the valve is inserted into the fractionation tray perforation by pressure applied to the cover plate, the hooking elements bend inward slightly to a smaller circumferential plane than that of the tray perforation. After insertion, the flexible legs spring back to their original outwardly projection. The tip of each hooking element then contacts the bottom of the fractionation tray surface to define and limit the upward motion of the valve. At least one downward projection from the cover plate defines and limits the downward motion of the valve into the tray perforation.
