Abstract: A reversing gear box is provided for use with an auger having a housing, a flight rotatably mounted therein and a motor for driving rotation of the flight. The gear box includes a drive shaft coupled to the motor and a driven shaft coupled to the flight of the auger at right angles to the driven shaft. A  drive gear is mounted on an end of the drive shaft between a pair of confronting driven gears mounted on the driven shaft. A sliding element is slidably mounted on the driven shaft between a forward position and a rearward position for selectively coupling the driven shaft to the drive gear via the driven gears. In the forward and rearward positions, rotation of the drive shaft in a forward direction corresponds to rotation of the driven shaft in respective forward and rearward directions. An actuator displaces the sliding element between the forward and rearward positions as desired.

Title: Closure device
Inventor: CHEN CHIH-HUNG
IPC: A44B19/26
Filed: 1999-06-10
Granted: 2009-09-29
Abstract: The closure device (121) includes first and sec-ond interlocking fastening strips (130, 131) arranged to be in-terlocked over a predetermined length and a slider (132) which slidably engages the first and second fastening strips. The fas-tening strips have a longitudinal X axis (160), a transverse Y axis (162) and a vertical Z axis (164). The slider (132) facilitates the occlusion of the fastening strips (130, 131) when moved towards a first end of the fastening strips and deocclusion of the fasten-ing strips when moved towards a second end of the fastening strips. The fastening strips (130, 131) are occluded and deoc-cluded by moving the first fastening strip relative to the second fastening strip in substantially the vertical Z axis (164). The fas-tening strips may also move in the Y axis (162), rotate or deflect during occlusion. In addition, the fastening strips may include a locking feature (1244, 1245) to prevent unintentional deocclu-sion.

Abstract: Selon l'invention, des sous-arborescences établies en fonction de la capacité de traitement d'un dispositif sont définies dans une arborescence de clés, où les clés sont affectées aux racines, aux noeuds et aux feuilles représentant les dispositifs d'une arborescence. Ainsi, une entité de gestion de chaque sous-arborescence crée un sous bloc de clés de mise en oeuvre réalisé dans l'entité. Un centre d'émission de clés crée alors un bloc de clés de mise en oeuvre que seule peut décoder une entité ayant une capacité commune en termes d'informations de capacité de l'entité. Chaque entité gère les arborescences partielles (sous-arborescences) de l'arbre de clés, crée un sous-bloc de clés de mise en oeuvre uniquement en fonction des noeuds des sous-arborescences ou des clés correspondant aux feuilles, et crée un sous-bloc de clés de mise en oeuvre que seule l'entité sélectionnée peut décoder au moyen du sous-bloc de clés de mise en oeuvre. Ainsi, il est possible de créer et de distribuer un bloc de clés de mise en oeuvre en fonction de la capacité de traitement d'un dispositif, la structure hiérarchique de l'arborescence de clés pouvant être gérée par sections.
