Abstract: The house or structure comprises a tubular metal supporting frame; and a first and a second structural members carried on selected portions thereof. The second member is slidable along the frame to form a gravity-controlled locking engagement therewith and also to allow the first member to be placed in position thereby instantly completing the assembly of the structure.

Abstract: Equipment and method for treating solid waste in which a non-oxidizing atmosphere is provided through which the shredded solid waste falls freely, unsupported and non-contacted, to prevent fusion of the plastics with each other, with other materials in the solid waste, or with the walls or components in the treating equipment. The unique atmosphere also allows a high treatment temperature to accelerate the debonding of fibrous combustible matter and fusion of the plastics into dense particles for substantially complete separation and recovery of plastics from the lighter fibrous but non-fusible combustible matter through gas classification during the free fall. This same atmosphere also produces a clean, unoxidized, homogeneous, storageable and highly combustible fuel derived from the fibrous combustible matter.

Abstract: The centrifuging weights orienting system comprises: a rotating flywheel provided therein with two centrifuging weights rotatable about a common axis. This axis is anchored at its ends to the flywheel and intersects at right angles with the axis of flywheel rotation. A control means is also provided which is actuated by the flywheel rotation to drive the centrifuging weights into oppositely directed rotations about their common axis. These oppositely directed rotations are synchronized so that at periodic, predetermined time intervals the centrifuging weights are caused to orient toward a common and fixed, prescribed spatial direction.
