Abstract: A system for collecting and storing solar energy as heat. In some embodiments, the system includes heat transfer passages for collecting and transferring heat, as well as ways of arranging passages to minimize thermal losses and redistribute heat. In some embodiments, the system includes an all-reflective solar collector with a largely clear aperture, using multiple light transfer conduits that rotate with the collector.

Abstract: An impact sprinkler drive is provided by an impact arm or spoon that rotates out of and counter-rotates into a water stream to impact and forward re-align a water emission portion from which the water stream emits. The impact arm is designed to, upon sufficient rotation, interfere with the water stream to reduce back-impact and reverse re-alignment of the water stream. The impact arm may be an impact spoon formed on an impact disc. The impact spoon is configured to increase the energy for forward re-alignment of the water emission portion including an increased length to permit a time delay before water flowing through the spoon applies force away from the water stream. The water acts upon spoon portions positioned at increased radial distances so that the water acts with a greater torque arm to impart rotational energy.

Abstract: A motorized sliding door mechanism for a motor vehicle having a body structure having a door opening and door. The mechanism includes a motor and drum assembly mounted on the door and a cable system including cable runs anchored to spaced points on the body structure. One cable run is wrapped in one direction around the drum and extends to an anchor point proximate the rear edge of the door opening of the body structure and a second run is wrapped around the drum in an opposite direction and extends to a point at the rear end of a rear guide track for the door which is mounted to the body structure. The cable runs extend from the drum to the anchor points via a pivotal hinge and a guide block at the rear of the door for guiding the sliding movement of the door.

Abstract: A power actuator for lifting a pivotal lift gate closing an access opening in a motor vehicle body.
