Abstract: A programmable dispensing system for a vending machine dispensing vending products. The system includes a vending machine having at least one helical coil for dispensing the vending product. The helical coil rotates in a first rotational direction 360 degrees plus an additional angular displacement by a motor when a vending product is selected from the vending machine. The helical coil dispenses a selected vending product when the helical coil is rotated. The helical coil is then rotated the additional angular displacement in a second rotational direction opposite the first rotational direction.

Abstract: An automatic cleaning system for a filtration system of an air delivery system is disclosed. The automatic cleaning system includes a filter constructed of a fine mesh material. The filter is mounted within a track running the width of the filter. An air intake device is mounted in the track and is driven along the track by a motor. The air intake device provides suction to remove particles captured by the filter within the air delivery system. The air intake device stores the removed particles in a collection tank. The automatic cleaning system may be utilized in an air conditioning unit having a filter or a clothes dryer having a lint tray.
