Abstract: A programmable machine for dispensing items, such as pills or capsules, in timed sequence has a cylindrical container element provided with a series of item receiving and dispensing compartments extending spirally therealong and opening into its circumferential surface for alignment with a discharge opening in a stationary cylindrical shell within which the container element is mounted for both rotary and axial movement concentrically over and along a microprocessor controlled, stepper motor, so as to sequentially bring the individual compartments into precise alignment with the discharge opening of the shell to discharge their contents into a delivery tray. The container element is mounted for spiral movement on and along a stationary spiral trackway as it is rotated. The compartments may be filled by turning the machine upside down and inserting items through the discharge opening.

Abstract: A reciprocating, double-acting cylinder pump supplies high-pressure water to a spray nozzle. A reciprocating, double-acting insecticide pump is mechanically and adjustably slaved to the water pump piston rod and discharges into the water line to provide an accurate, proportionate amount of insecticide to the water at the discharge nozzle. Control of the flow of water and insecticide occurs at the nozzle.
