Abstract: A gas delivery apparatus configured for use with a mechanical ventilator having an atmospheric inlet for drawing in atmospheric gas includes a connecting device configured to connect to an oxygen supply and an air supply and to deliver mixed air and oxygen gas to the atmospheric inlet of the mechanical ventilator. The connecting device further includes a user control for adjusting a fraction of oxygen in the mixed air and oxygen gas. The connecting device comprises a reservoir configured to hold a volume of the mixed air and oxygen gas.

Abstract: A lighting fixture arrangement, an adjustable lighting fixture connector, and a method of installing a lighting fixture arrangement.

Abstract: A foam panel cutting machine for cutting foam panels used in insulated building panels. The foam panel cutting machine has a feeder system feeds the foam panel through the cutting blades. The cutting machine additionally includes a frame, a plurality of upper rollers and a plurality of lower rollers rotationally mounted to the frame. The foam panel cutting machine can be constructed so that it may be portable. One embodiment includes the upper rollers on an adjustable head that can adjust the gap distance between the upper and lower rollers so that foam panels of various thicknesses may be cut. The cutting blade may be a hot-knife wherein the blade is heated by passing an electrical current through it. The cutting blade may have a “L” or “J” shape to cut kerfs into the foam panel that receive metal studs to form an insulated building panel.

Abstract: An apparatus and associated method for constructing prefabricated foam panels is provided. While making a longitudinal pass over a foam block, the apparatus flattens the foam block, cuts longitudinal kerfs in the foam block, and draws metal studs into the kerfs. The apparatus comprises a unique, heated blade having a shape similar to the cross section of a metal stud. The blade kerfs foam blocks, including blocks made of recycled or low-grade foam. The associated method includes kerfing the foam blocks by passing the blade through the foam blocks and drawing metal studs into the kerfs.
