The second pair of web belts overlap with the downstream end of the first pair of belts, but are disposed lower than the first belts.

Abstract: A bale bagging apparatus for bagging round bales in tubes of plastic film includes a hoop and an annular flexible tube support projecting to the rear of the hoop. The tube support conforms to the shape and size of the bales being bagged, so that a tubing may be used that is fairly close in size to the size of the bales. This reduces the amount of air inside the bag and the ultimate looseness of the bagging tube on the bale, which affects its wind resistance and allows the bagging of bales in smaller tubes, which significantly reduces the cost of plastic film.

Abstract: Motor apparatus which converts hydraulic energy and change of state heat energy to mechanical energy. The motor includes a main chamber divided by a piston into first and second portions. During a first half cycle or hydraulic power stroke, a valve places the first portion of the chamber in fluid communication with a source of pressurized, saturated liquid and the second portion of the chamber in fluid communication with a drain port. A switch senses the end of the hydraulic power stroke and causes the valve to move to a second position wherein the first and second portions of the chamber are placed in fluid communication with one another to form a common motor chamber and drive the piston in an expansion power stroke. Power is derived from the working fluid during the piston stroke in each direction. The motor finds particular application for energy recovery in an absorption refrigeration system.

Abstract: The invention is for the prevention of power piston overstroke in a Stirling cycle machine, wherein there is a gas valve which vents the gas spring acting upon the displacer. The valve and its accompanying control system switch on a leak in the gas spring to vent the gas spring upon piston stroke beyond a selected magnitude. This reduces the spring constant which reduces the displacer amplitude and phase lead over the power piston and thereby reduces power output.
