Title: Dispositif de fixation de capteur a glissement accru
Inventor: DALY PAUL D
IPC: F02M35/04
Filed: 2000-10-12
Abstract: L'invention concerne un dispositif (10) de capteur de véhicule comprenant un capteur (14) de véhicule constitué d'un matériau de densité relativement faible, destiné à un composant (12) de guidage de fluide d'un véhicule, tel qu'un collecteur d'admission d'air comportant un élément (18) de réception du capteur constitué d'un matériau à densité relativement élevée. Lorsqu'on insère le capteur (14) dans ledit élément (18) de réception, la surface (30) d'engagement du capteur, relativement plus tendre, est déplacée de son état de repos par la surface (26) d'engagement plus dure de l'élément de réception. La surface (30) d'engagement plus tendre du capteur est élastique et tente toujours de revenir à sa position de repos afin de soulager la zone soumise à des tensions élevées. En essayant de revenir à son état de repos, la surface (30) d'engagement du capteur « glisse » vers une zone soumise à de plus faibles tensions. Le corps (14) du capteur réagit en « glissant » vers le composant de guidage de fluide du véhicule. L'invention exploite ainsi le soulagement des tensions résiduelles créées lors de l'insertion du corps (14) du capteur afin de resserrer le montage du capteur dans ledit composant (12) du véhicule.

Title: Method for utilizing triethylaluminum to prepare an alumoxane support for an active metallocene catalyst
Inventor: CHANG MAIN
IPC: C08F4/639
Filed: 1989-11-07
Abstract: ABSTRACT OF THE DISCLOSURE      This invention relates to a process for preparing a supported metallocene alumoxane catalyst for use in the polymerization of olefins.  The invention particularly relates to the use of silica gel containing from about 6 to about 20 per cent by weight adsorbed water as the catalyst support material.  It has been found that such silica gel may be safely added to a solution,  of trialkylaluminum to  form by direct reaction with the adsorbed water content of the silica gel catalyst support material  the  majority  of  the  alumoxane  component requirement of the catalyst system.  An alkylalumoxane coated silica gel is formed to which a trimethylaluminum treated metallocene  may be added and the resulting material dried to free-flowing powder.  The dry free flowing powder may then be used as a supported metallocene alumoxane catalyst complex for gas phase or liquid phase polymerization  of  olefins.   The  supported catalyst produced by such procedure has an activity at least comparable to a catalyst of similar composition which is produced  exclusively  with  trimethylaluminum  as  the alumoxane forming aluminum alkyl.

Patent CA-2036568-A1 (CA)
Inventor: LOVE SAMUEL D
IPC: B60K28/06
Filed: 1991-02-19
Abstract: A safety alertness monitoring system is provided for maintaining an operator alert.  A switching means is provided which must be actuated by the operator within an adjustable time period to prevent a first alarm from being activated.  Upon detection of this first alarm, the driver must actuate the switching means, indicating his alertness and restarting the  first time period,  otherwise after expiration of a second time period a second alarm will be activated to further alert the operator and passengers. This  second  alarm  will  remain  activated  until  the switching means is actuated restarting the process.  The present invention also includes a waiting mode whereby the timer  can  be  deactivated  while  driving  in  congested traffic.    During the waiting mode,  a  third alarm  is activated to provide some alerting function.  The device also includes a first electrical output which is usually ON, but is turned OFF when the buzzer sounds.  This output can be used to supply power to, for example, games for the enjoyment  of  children.    Since  the  driver  in  effect "controls"  the  power  supplied  to  the  first  output, additional interaction of passengers with the driver is ensured, thus further raising the alertness of the driver.       Additionally, an entertainment/educational game is provided which teaches players thereof about geography. The safety alertness monitoring system can be used as a timer with the game.  The game includes a playing surface having  a  geographical  area  divided  into  subregions illustrated thereon, the geographical area and subregions having geographically significant shapes.  A plurality of elongated, flexible members (e.g., colored strings) having fixed, equal lengths are provided as playing pieces, one for each player (or team).  An object of the game is to accumulate points while attaching ones playing piece to the playing surface within subregions to achieve  some predefined  goal  (e.g.,  extending one's  playing  piece across the geographical area or forming a loop with one's playing piece), while attaching one's playing piece to at least a minimum number of subregions.  Players draw cards which  include  indicia  corresponding  to  one  of  the subregions.   Players attach a portion of their playing piece to the playing surface within a subregion if they can locate the subregion within a preset time period. Players accumulate points by identifying the subregions on the playing surface and by reciting additional information about the selected subregion (e.g., if the subregion is a state or country, by reciting the capital of the state or country) also within the preset time period.  When played within an automobile, the operator can actuate the timer, which assists in maintaining a level of alertness in the operator.
