Abstract: A system for controlling and safeguarding the dispensing of fluids used in servicing centers is provided. The system is devised to provide lubricants to motor vehicles and includes a programmable system that comprises means to activate and deactivate a plurality of fluid dispensing pumps including a shut down of pump feeding air pressure to prevent fluid spills and to preclude the theft or dispensing of fluids at unauthorized times such as at times outside normal servicing hours. The invention also affords improved central proprietors of servicing facilities to set and monitor operable pump periods and includes an automatic shut down, until reactivated by a master key, of pump functions at a specified time of day.

Abstract: A pump priming apparatus including a housing through which fluid object material may be urged to flow, the housing including an intake portion and a pumping portion downstream from the intake portion. The apparatus further includes a piston assembly carried for reciprocation in the housing, the piston assembly and the housing being configured such that a partial vacuum is developed in the pumping portion of the housing as the piston assembly moves through the pumping portion of the housing toward the intake portion of the housing and such that the partial vacuum is substantially released upon the movement of the piston assembly into the intake portion of the housing, thereby causing the fluid object material in the intake portion of the housing to flow into the pumping portion of the housing.

Abstract: There is provided an apparatus and method for the collection and transfer of a liquid, which is preferably waste oil. The apparatus includes a tank having a top opening with a hollow tube projecting from the top opening into the interior of the tank. A hollow stem is slidably received within the hollow tube. A funnel, which initially receives the liquid, is attached to the top end of the stem which is located outside of the tank. An opening is provided in the wall of the stem near the lower end which is located inside the tank. A cover plate is received about the bottom of the stem.
