Abstract: A conduit support apparatus for concrete installation which, in the preferred embodiment, includes a collar portion supported above a concrete form by at least one support member, the concrete support apparatus fastened to the concrete form with fasteners which pass through holes in horizontal bottom sections of the support member and into the concrete form, the dimensions of a preferred embodiment of the conduit support apparatus being uniquely balanced to impose a bend on a supported flexible conduit with a curvature within an optimum range of curvatures which is defined between two undesirable limits described by a first small curvature which results in the upper section of the conduit bending back into the form space and a second large curvature which results in the flexible conduit collapsing into itself to reduce the amount of work space within the flexible conduit below an acceptable level.

Abstract: A conduit positioning and accessing apparatus, and resulting concrete form structure, comprises a compression type coupling, a flange member rigidly attached to the coupling, a filler element which removably surrounds a portion of the coupling and fastening elements for removably fastening the apparatus to a concrete form, wherein the filler element is formed of polystyrene foam or other easily disfigured material, and wherein an access cavity is defined in the hardened concrete upon removal of the form and filler element.

Abstract: An improved toilet stool having an annular conduit seat with intake openings in communication with the inside of the toilet bowl. The improvement being a ventilating means which comprises an adapter plate situated underneath a tank. The adapter plate has a structure defining a conduit which is in communication with the toilet bowl through the intake openings of the seat. A housed filter element is in communication with the conduit seat through the conduit of the adapter plate, and a means is attached to the filter for removing normally contaminated air from the inside of the toilet bowl through the intake openings, the conduit of the adapter plate, and the filter element, in the order stated, for deodorizing the normally contaminated air and passing it into the surrounding atmosphere.
