Abstract: A remotely openable containment system employs a bag which receives contents such as grounding cement and employs a closure member which is secured by a bale. The closure member is attached to one end of the bag adjacent an opening. End portions of the bag are wound around the closure member and secured by the bale. The bale may include a pair of laterally spaced pins which are received in spaced bores of the closure member. At the installation site, the bag is lowered by a line into a hole. At the bottom of the hole, a line on the bale is pulled to release the bale and to permit the contents to discharge through the opening in the bag. Both the bag and the bale are removable from the hole by the attached lines.

Abstract: A fan assembly has a fan housing defining mounting apertures, a sheet metal mounting member for mounting the fan housing thereon, mounting tabs extending outwardly of the mounting member and received within the mounting apertures of the fan housing, and threaded fasteners received within the mounting apertures of the fan housing and engaging both the mounting tabs and the fan housing to secure the fan housing to the mounting member. Each mounting tab is formed by piercing the sheet metal mounting member with a forming tool, and moving the forming tool through the pierced mounting member to thereby move the pierced metal in the shape of the tab outwardly of the mounting member. The mounting tabs are received within the mounting apertures of the fan housing, and self-tapping fastener are inserted into the mounting apertures of the fan housing and engage both the fan housing and the mounting tabs to secure the fan housing to the mounting member.
