Abstract: A kit collapsible readily to be confined neatly in a foldable two-part travelling case embodied with the kit and to provide, when extended, a sauna bath apparatus embracing a water-tight, water-collecting base receptacle, a porous, plastic web covered cot overlying and supported by said receptacle, a tent overlying and enclosing said cot and extending downwardly between said cot and said receptacle, a foldable cushioned head stool being included in said kit and located at one end of said tent opposite a hole in an end wall of the latter to facilitate the patron reclining on said cot with his head extending through said hole and resting on said cushioned stool. Plural electric steamers deposited in said receptacle are controllable by the patron to furnish a desired degree of heat and humidity to the interior of the tent.

Abstract: An engine unit operable independently or joined in multiples of two or more units for smoothing out the torque flow at slow speeds, each unit including a fuel-suction-compression assembly and a power generating assembly employing the same main shaft and separate valve shafts gear driven therefrom at a two-to-one ratio. Each assembly has a plate-like block bored out to provide a central cylinder chamber and two planetary cylindrical valve chambers. Fixed on the main shaft and rotating in said central chambers are two like rotors having cylindrical hubs and two arcuate segmental pistons extending diametrically therefrom to make smooth sealing rotational engagement with the walls of said central chambers. Fixed on said valve shafts are arcuate segmental valves making smooth sealing rotational engagement with said valve chambers and said rotor hubs.
