Abstract: A mobile apparatus for removing floor coverings. The apparatus has a main frame supported by wheels and includes a scraper blade mounted on the front of the frame and a rotary cutter assembly mounted underneath the frame with controls whereby the scraping blade is used independently of the rotary cutters and the rotary cutters are use independently of the scraping blade, and wherein the rotary cutters may be moved from underneath the frame to one side of the frame for ready access to the cutter members of the rotary cutters.

Abstract: A portable corral which is folded into a retracted position behind a towing vehicle for transport from one location to another, and is folded to an expanded, usable configuration for movement along side the path of travel of the towing vehicle to trap cattle or the like who may, for example, be feeding in the path of movement of the corral.

Abstract: A rotary cutting attachment for removing linoleum, tile, mastic, grout, adhesive and the like from floors. The cutting attachment includes a drive plate, an elastomeric ring, a cutter head, a block plate, six cutter blocks and three cutter inserts per cutter block. The elastomeric ring separates the drive plate from the cutter head and allows the attachment to adjust to the contour of the floor. The drive plate and the cutter head have sets of gears which mesh to transfer rotation of the drive plate to the cutter head. In turn, an offset member of the cutter head mates with an offset bore of the block plate to transfer rotation of the cutter head to the block plate. The six cutter blocks are removably mounted to the block plate and three cutter inserts are removably mounted to each cutter block. Typically, three cutting attachments, each driven by a hydraulic motor, are utilized in concert to remove a floor covering.

Abstract: A bent axis rotary piston engine which includes features improving its operational characteristics. The engine provides the capability of dual output power, improved cooling and gas flow through the engine, supercharging and improved scavenging of the exhaust. The engine also includes an oiling system, an improved bent axis piston design, and a rotary valve system provided by the pistons and cylinders. The engine is also adapted to incorporate auxiliary equipment such as a starter and magneto system, and an electrical power generator. Other features are disclosed.

Abstract: An internal combustion engine having two rotating cylinder blocks in each of which is formed a plurality of cylinders to receive portions of pistons that extend partially into each cylinder block. The cylinder blocks are angled relative to one another and the pistons are similarly angled to cause variation in the free volumes of the cylinders as the cylinder blocks rotate. A support shaft passes through the centers of the cylinder blocks to provide support for the cylinder blocks via bearings on the support shaft. Air is introduced into the cylinders via central cavities in the cylinder blocks and fins and slots are formed on, and in, respectively, the interior walls of the cavities to impart rotation to air in the cavities. A series of rings, through which the cylinders pass, are formed on the end of each cylinder block that faces away from the other cylinder block to circulate cooling air drawn into a housing in which the blocks are mounted about the cylinders.
