Abstract: A device for simple attachment to a water closet and tube extending to a location outside the building and room in which the closet is located. The device comprises a relatively small hollow housing having an opening for receiving gases when attached to the lid or seat of the closet, and an exit port and extension for connecting to the tube. The housing receives gases from the closet and directs the same from the housing to the tube and thus from the room and building. The gases are conveyed form the housing either by a motor driven fan or by normal convection currents.

Abstract: An electrical box for receiving a wiring device and having means for the reception of a conductor for connection to the wiring device. A relatively flat conductor retaining member is disposed in opposed tracts provided in the box that allows slidable movement of the flat member in the box. The member is adapted to secure a conductor in the box when slidably moved to engage the conductor, and for releasing the conductor by simply lifting the rear edge of the flat member above a ledge in the front of the box, and sliding the flat member past the ledge and from the conductor.

Abstract: A wall and corner structure for an enclosure that includes vertically disposed, load bearing board members resting on a foundation structure. Horizontal boards are secured to opposed sides of the vertical board members at locations thereon that provide horizontal spaces between the horizontal boards. A double wall corner arrangement is provided by abutting a first set of inner and outer boards against the inner board of a second set located at a right angle to the first set. This allows the second set to extend to or beyond the outer board of the first set. Such an arrangement alternates at the corner in a vertical direction. Mortar material is located in the horizontal spaces between the horizontal board, the mortar extending to the corner to provide a continuous seam.
