Abstract: A loose material recovery apparatus such as for recovering foam plastic packaging elements has an overhead bin for containing the material. The bin has a storage chamber for storing the material and an outlet from which the material in the bin is dispensed. A vacuum assembly above the storage chamber includes a container having a bottom door, an actuating member, and a motor. A storage compartment is defined within the container between the motor and the bottom door. The bottom door is mounted for movement between a closed position for retaining the material in the storage compartment and an open position allowing the material to fall from the compartment into the bin storage chamber. When the motor is energized movement is imparted to the actuating member to close the bottom door and create a vacuum in the storage compartment for drawing material to be recovered into the compartment through a suction hose.

Abstract: Apparatus for use in developing and testing a control system for an internal combustion automobile engine. A housing is located in the automobile where it can be visually observed by an operator of the automobile. Electrical circuitry is installed in the housing. A wiring harness interconnects sensors and electromechanical devices with the circuitry. A programmable memory has a plurality of addresses which are selectably accessible, different addresses in the memory containing information relating to different aspects of the system. Information stored in a selected memory address is changeable thereby changing the operating characteristics of the system. The contents stored in a selected address are visually displayed so an operator can visually verify the information stored therein. Operation of the system while the engine is running is visually monitored to determine system performance during road tests, performance of the system thus being observable under actual driving conditions.
