Abstract: A bracket attaches rigidly to the steering head tube member at the front of a motorcycle frame, so that the fork steering assembly can be relocated and pivotally attached to the front of the bracket. The bracket permits the fork steering assembly to be mounted in a new position which is in front of, and higher, or lower than its former, manufacturer's specified. position. The steering axis can be positioned such that it is tilted at a greater angle of inclination from the vertical, permitting use of longer fork tubes. The bracket permits any motorcycle to be reversibly modified to have the appearance and handling characteristics of a chopper style motorcycle. No modifications to the motorcycle are needed, in order to relocate the fork steering assembly, and to attach the steering assembly and bracket to the head tube and frame. Thus, the originality and value of the motorcycle, if the owner decides to, later, revert to the original appearance, is maintained.

Abstract: A mine stopping and method of installing a mine stopping in a mine passageway having air flowing through the passageway in a first direction are disclosed. The mine stopping includes a rigid wall extended across the passageway to close the passageway. The wall includes a first wall section extending at a first angle relative to the direction of airflow through the passageway and a second wall section extended at a second angle relative to the direction of airflow such that the wall sections are arranged in a non-coplanar, non-parallel relationship with respect to one another. There are openings in the wall to permit the passage of air therethrough. The second angle is oblique to the direction of airflow whereby air flowing through the passageway strikes the second wall section at an oblique second angle to thereby reduce the dynamic air pressure exerted on the wall.

Abstract: L'invention concerne un procédé et un système de collecte d'informations associées à des activités de lavage de vaisselle. Les articles à nettoyer par une machine à laver la vaisselle sont placés dans des paniers conçus pour s'adapter à l'intérieur d'une chambre de lavage de la machine à laver la vaisselle. Chaque panier reçoit un identificateur (ID) unique. Il n'existe pas deux paniers ayant le même ID unique. Une étiquette d'identification par radiofréquence (RFID) est intégrée dans ou placée sur l'enveloppe extérieure de chaque panier. L'étiquette RFID d'un panier est programmée avec l'ID unique affecté au panier. Un lecteur RFID lit l'ID unique de chaque panier à mesure que les paniers sont placés dans la machine à laver la vaisselle. Le lecteur RFID transmet l'ID unique à un ordinateur central dans lequel l'ID unique est marqué par une référence temporelle, stocké et éventuellement chargé dans un ordinateur serveur. L'ID unique et la référence temporelle associés sont analysés par l'ordinateur serveur, l'ordinateur principal ou un ordinateur client relié à l'ordinateur serveur afin de contrôler le rendement de la machine à laver la vaisselle. Par exemple, l'analyse peut calculer le nombre total de paniers reçus par la chambre de lavage sur une durée donnée.
