Abstract: A low speed cooling fan that is designed to cool individuals located in large industrial buildings. A fan with a diameter between 15 to 40 feet consisting of a plurality of blades, with each in the shape of a tapered airfoil, is driven by an electric motor to produce a very large slowly moving column of air. The moving column of air creates a uniformly gentle circulatory airflow pattern throughout the interior of the building thus promoting the natural evaporative cooling process of the human body at all locations inside the building.

Abstract: An apparatus for use with a vehicle having an open-topped cargo carrying compartment with first and second side walls which includes first and second elongated side rails attached to the side walls, respectively, and first and second connectors mounted on the first and second side rails, respectively, for movement along the associated side rail. The connectors can be locked in position along their associated side rails. First and second retainers are coupled to the first and second connectors, respectively, for movement with the connectors and the retainers are adapted to extend into the cargo-carrying compartment. Each of the retainers can retain one side of a divider in position within the cargo-carrying compartment.

Abstract: A pressure roller for roofing machines is disclosed which is capable of following dips, rises, and pitch variations in the roof surface along its width while remaining stiff and straight in the directions parallel to the roof surface. A uniform force distribution along the width of the roller is achieved by mounting the roller for rotation about a leaf spring which, in its unstressed condition, has the shape of a curve.

Abstract: A machine for laying a roll of sheet material comprising a frame, a roller rotatably mounted on the frame and a pair of wheels rotatably mounted on the frame. An expandable mandrel is provided for mounting the roll of sheet material. The mandrel is mounted on the frame by two sets of jaws, each of which is controlled by a double set of toggle mechanisms.
