Abstract: A portable hydraulic log splitter assembly having separate power pack and log splitting modules is disclosed. The pump for the log splitter can be powered by either an electric or gas motor. The pump is operated in connection with a four position regenerative safety release valve that is biased toward neutral in the forward position so as to automatically disengage the cutting blade if the valve's handle is not manually held in an operational position by the user. The valve permits an increase in driving force applied to the cutting blade up to a predetermined limit to overcome log resistance. The valve has a further regenerative feature allowing for faster splitting strokes by the cutting blade. In order to reduce weight for portability purposes, the cutting blade (formed of tool steel) is mounted on a relatively lightweight aluminum base. Through holes in the cutting blade receive molten aluminum when the base is molded so as to be integrally mounted on and locked into the base.

Abstract: A portable table for a wheelchair storable adjacent the frame of the wheelchair. The portable table is attached to the frame of the wheelchair and includes a tilting device for varying the angle of the table top relative to the horizontal. The table top is also slidably connected to the wheelchair frame enabling lateral movement, as well as tilting of the table top relative to the horizontal. The table top includes foldable sections held together by a magnetic retaining device until the sections are separated by the user.
