Title: Recliner assembly having a shaft with an annular recess
Inventor: VILLARROEL RANDY
IPC: B60N2/20
Filed: 2001-12-10
Granted: 2010-01-26
Abstract: A recliner assembly for operatively interconnecting a seat back and a seat cushion allowing pivotal adjustment of the seat back relative to the seat cushion. The recliner assembly comprises an inner disc fixedly secured to the seat cushion and an outer disc fixedly secured to the seat back. The outer disc is rotatably nested within the inner dis and includes an annular rim of gear teeth extending radially inwardly. At least one pawl is adapted for lockingly engaging the annular rim of gear teeth on the outer disc and is disposed between the inner and outer discs. The pawl is radially moveable between a locked position, wherein the pawl is lockingly engaged with the annular rim of gear teeth on the outer disc, and an unlocked position, wherein the pawl is disengaged from the annular rim of gear teeth on the outer disc. A biasing member extends between the pawl and the inner disc for biasing the pawl in the locked position. A cam shaft assembly is rotatably journaled to both of the inner and outer discs for actuating the pawl between the locked and unlocked positions. The cam shaft assembly comprises a cylindrical shaft and a cam. The cylindrical shaft has proximal and distal ends. An annular shoulder is formed in the cylindrical shaft disposed between the proximal and distal ends and extending radially outwardly from the shaft. An annular recess formed in the annular shoulder. A ramped surface extends from the annular recess and tapers towards the proximal end. The cam has a center bore and a plurality of teeth extending radially inwardly from the bore. The cam has a hardness greater than that of the shaft. The cam is press fit onto the shaft and locating axially against the annular shoulder, such that material scraped from the shaft during assembly of the cam onto the shaft is displaced into the annular recess to ensure the proper alignment of the cam against the annular shoulder of the shaft.

Abstract: A structure comprising bodies having a functional surface property bonded to a substrate via a siloxane polymer adhesive. The structure may comprise a novel composition comprising a siloxane polymer having carbon bodies bonded thereto by direct carbon to silicon bonds. This composition may be used to bond carbon particles through a medium comprising the siloxane polymer to a vitreous, metal, plastic or other nucleophilic substrate. Alternatively, the bodies may comprise alumina, silicon, zeolite, organic polymers or other nucleophilic compositions, which are bonded directly to silicon atoms of the siloxane polymer. To bond carbon or other nucleophilic bodies to the substrate, the substrate is contacted with a mixture of the bodies and a hydrosiloxane polymer. The mixture is heated to cause the polymer to be bonded to the nucleophilic bodies, typically by C-Si. C-O-Si. Si-O-Si or Si-O-Al bonds. and to the substrate by reaction with the surface silanol or other nucleophilic groups.      Chromatographic methods using a column comprising the novel composition are also disclosed.

Granted: 2009-09-29
Abstract: La présente invention concerne un procédé et un dispositif servant à l'analyse d'un échantillon d'analysat en solution dans un solvant. On utilise un dopant, soit séparément, soit comme solvant de la solution d'échantillon. On nébulise la solution d'échantillon, notamment dans un nébuliseur, et on évapore le solvant. Le courant d'échantillon s'irradie dans une zone sous pression atmosphérique, soit à l'état liquide juste avant la formation d'un brouillard, soit à l'état liquide avant la formation d'un brouillard de gouttelettes, soit enfin à l'état de vapeur après l'évaporation des gouttelettes du brouillard, de façon à ioniser le dopant. Par la suite, les collisions entre le dopant ionisé et l'analysat, directement ou indirectement, aboutissent à l'ionisation de l'analysat. On fait passer les ions d'analysat de la zone d'ionisation sous pression atmosphérique à l'analyseur de masse en vue de l'analyse de masse. Il s'est avéré que ce procédé aboutit à une bien meilleure ionisation pour certaines substances que par ionisation chimique sous pression atmosphérique.

Granted: 2008-06-17
Abstract: The objective of the present invention is to irradiate a relatively large skin area evenly with laser beams. A plurality of semiconductor laser diodes are arranged to form two lines with the semiconductor laser diodes of one line staggered with those of the other line, and the semiconductor laser diodes of each line are so inclined that their laser beams may focus on a single line. With this arrangement the plurality of laser beams provide a linear distribution of narrow beam, and the scanning area on the skin can be expanded accordingly.  The beauty treatment on the skin or the depilation treatment can be expedited significantly.   Advantageously the focussing points of the laser beams are distributed at an increased density, and the irradiation strength averages everywhere to attain the even beauty treatment.

Abstract: A process of bulk filling containers which includes the steps of arranging a number of containers upside down in a tray (24) that has a raised peripheral lip (26).      This tray full of containers is then placed in a vacuum chamber (28) which is then evacuated to a predetermined level below atmospheric pressure. Liquid (36) is then introduced into the tray through a reservoir (38) and conduit (40) which penetrates the wall of the vacuum chamber and the vacuum within the chamber is gradually released at a rate that draws the liquid into the containers. At this point in the process unwanted liquid is rinsed away and the tray is removed from the chamber and turned right side up. The final step is to seal the top of the containers with an appropriate cap, barrier, tip or connection. A second embodiment adds a step to the process by positioning the containers upside down in a rack (74) and positioning the rack directly above the tray containing the liquid. The rack is then lowered until the container necks are immersed in the liquid. The level of liquid is maintained as above and the balance of the process is conducted the same as the preferred embodiment.

Title: Determination of supplemental fuel requirement and instantaneous control thereof involving regenerative thermal oxidation
Inventor: RUHL ANDREAS C H
IPC: F01N3/10
Filed: 2001-12-07
Granted: 2008-04-01
Abstract: A control system for a regenerative thermal oxidizer in which contaminated air is first passed through a hot heat-exchange bed and into a communicating high temperature oxidation (combustion) chamber, and then through a relatively cool second heat exchange bed. The apparatus includes a number of internally insulated, ceramic filled heat recovery columns topped by an internally insulated combustion chamber. Contaminated air is directed into heat exchange media in one of said columns, and oxidation is completed as the flow passes through the combustion chamber. From the combustion chamber, the now clean air flows through another column containing heat exchange media, thereby storing heat in the media for use in a subsequent inlet cycle when the flow control valves reverse. The resulting clean air is directed via an outlet valve through an outlet manifold and released to atmosphere or is recirculated back to the oxidizer inlet. A combustible fuel such as natural gas is added to the inlet-contaminated air prior to its entry into the hot heat exchange column when the contaminant concentration in the contaminated air falls below a predetermined level. The oxidizer is preferably integrated with a web dryer, such that hot aire from the combustion chamber is supplied to the dryer.
