Abstract: A life support system providing breathable gas from a high pressure source utilizes an exhaled gas treatment device to eliminate harmful components from exhaled gas and incorporates a novel rebreathable gas mixing and supply device in which inhalation pressure of the user activates a fresh breathable gas supply valve which, in turn, jets the fresh breathable gas into and through a mixing chamber, providing a booster type suction force to pull exhaled gas through the treatment device, mixing the treated, purified gas with the fresh gas and supplying the resultant mixture to the user.

Abstract: A spacesaver tiltable storage unit is disclosed comprised of a pivotable frame, with dimensions compatible for mounting between exposed 2 inch .times. 4 inch or 2 inch .times. 6 inch studs on 16 inch centers and fitted with storage elements for containment of small parts and components. Such a device as proposed here provides a means for storage space saving and efficient use of such common expendables as 1-pound coffee cans or a variety of food jars, each of which has its own removable top for dust-free storage of small parts. The frame is pivoted into the recess between exposed studs when not in use, and is held in the closed or recessed position through gravity, by reason of the center of mass of stored parts and components being positioned, in the storage elements, aft of the pivot line of the unit.
