Abstract: A vehicle for scraping a floor has an adjustable blade with various widths mountable thereon and is an appropriate vehicle size for moving through a standard door.

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.
