Abstract: A pager receiver based system provides a method and an apparatus for receiving and detecting a tornado alert or other severe weather alert from the National Weather Service, determining the region or grid block to which the alert applies, and broadcasting an alert signal to a plurality of pager receivers, all programmed with the same sub-address, within that region or grid block.

Abstract: A repair kit for a sliding glass patio door having worn original wheel assemblies includes an edge bracket with an associated edge wheel for installation on a leading edge of the door and a side bracket with an associated side wheel for installation on a side of the door near a trailing edge. The edge wheel and the side wheel support the weight of the door, while the worn original wheel assemblies are left in place for guiding the door. An original track for the door provides a guideway on which the door and the original wheel assemblies travel. The edge bracket includes an edge plate that can be fastened to the leading edge, and a frame is attached to the edge plate. An axle is mounted in the frame, and the edge wheel is mounted on the axle. The side bracket has a side plate and a frame. The frame has legs mounted parallel to the side plate for holding an axle perpendicular to the side plate. The side wheel is mounted on the axle located within the frame on the side plate.
