Abstract: A harvesting apparatus for harvesting generally spherical fruit by severing each fruit from its stem and conveying it using air flow into a receptacle. The harvesting apparatus includes a tubular body with a clamshell cutter for severing items of fruit from their stems, and a retractable throat that is able to restrict and then allow passage of the fruit. The apparatus further includes a control unit that can control the clamshell cutter and the throat. A funnel-shaped orifice is preferably included at the harvesting end of the tubular body. When a piece of fruit enters the harvesting end, it contacts the throat and blocks the airflow. The control unit senses the resulting pressure drop, and then activates the clamshell cutter while causing the throat to open so as to allow the piece of fruit to pass through the tubular body and into the receptacle.

Abstract: An apparatus is disclosed for harvesting items of spherical fruit by severing them from their stems and conveying them by means of air flow into a receptacle. The harvesting apparatus includes a tubular body with a clamshell cutter for severing items of fruit from their stems, and a retractable throat that is able to restrict and then allow passage of the fruit. The apparatus further includes a control unit that can control the clamshell cutter and the throat. A funnel-shaped orifice is preferably included at the harvesting end of the tubular body. When a piece of fruit enters the harvesting end, it contacts the throat and blocks the airflow. The control unit senses the resulting pressure drop, and simultaneously activates the clamshell cutter while causing the throat to open so as to allow the piece of fruit to pass through the tubular body and into the receptacle.

Abstract: Reflector means is placed in the path of the energy beam of a radar to incept a peripheral portion of the beam and divert sufficient radar waves to cover a portion of the field-of-view in the opposite direction.
