Abstract: An access door is suitable for installation in a structure such as a building and allows ready access to an enclosed region of the structure. The access door includes a door frame that can be mounted on the structure and that forms an access opening. A panel removably covers the access opening on an exterior side of the door frame. Two parallel connecting links are pivotably connected both to the door frame and to the panel in a manner permitting the panel to be moved from an open position where the access opening is uncovered to a closed position where the panel covers the access opening. A frame member connects the two links together in a rigid manner. One or more threaded fasteners can be used to detachably connect the panel so that it is secured in the closed position. In one embodiment, a single screw can detachably connect the panel to a pivotable connecting frame that includes the two links. In another version, the panel can be detachably and directly connected to the door frame by fasteners.

Abstract: A modular in-wall medical services unit for medical care facilities. A frame supports a cabinet with a cover panel providing electrical and/or gas outlets. Built-in electrical and gas conduits are included. A junction box and ends of the gas conduits near the top of the frame are accessible after wallboard is applied. Thus, wallboard can be installed before or after wiring is completed and gas connections are made. The self-aligning cover panel is "floatingly" supported on the frame so that a bead of sealant can be applied around the edge before the cover panel is "snugged up" to the wall and secured. The trim flanges on the cover panel include vertical equipment mounting tracks. Manufacturing is simplified by making the height of the frame adjustable; the same frame elements can be used to assemble units for different ceiling heights, decreasing the number of required parts in inventory and expediting assembly.

Abstract: L'invention concerne un procédé et un appareil permettant de broyer une substance particulaire, telle que des matières premières de ciment, du ciment non broyé ou analogues, dans un broyeur à cylindres (1), lequel procédé consiste à soumettre ladite substance à une force de pression dans une zone (13) située entre des surfaces tournantes opposées où la substance est dirigée vers la zone de broyage au moyen d'une barre de chariotage (11). Le procédé de l'invention est caractérisé en ce que la substance placée dans la barre de chariotage (11) est accélérée sous l'action de la gravité jusqu'à une vitesse recherchée sans admixtion importante d'air, l'appareil de l'invention étant caractérisé par le fait que la barre de chariotage est en configuration sensiblement verticale, avec une section transversale réduite vers le bas, la diminution de la circonférence transversale de la barre par unité de hauteur décroissant vers le bas. La configuration de la barre de chariotage décrite a montré, d'une manière surprenante, qu'au-delà d'une hauteur ou d'une chute donnée la substance peut atteindre des vitesses élevées, et ce sans entraîner une admixtion d'air dans la substance. Ainsi, il a été montré que la substance peut atteindre des vitesses proches de la vitesse obtenue dans le cadre d'une chute libre des particules individuelles.
