Patent number: 6179163Abstract: A system (21) for monitoring the quantity of air in a liquid-state fuel stream discharged from a dispenser (20). The dispenser includes a pump (26) that draws the fuel from a storage tank (22). The fuel stream discharged from the pump is applied to an air separator (38) in which the air and vapor-state fluids are removed from the fuel stream. The gas-removed fuel stream is allowed to flow to nozzle (44) for dispensing. The gas stream created by the air separator is flowed to an air elimination chamber (41). The fuel in the gas stream separates from the air in the air elimination chamber and is returned to an input side of the pump. The air in the air elimination chamber is vented through a fixed opening to the ambient environment. The monitoring system (21) includes a transducer (48) that monitors the rate of air flow through the air elimination chamber. This monitoring may be performed by monitoring the air pressure in the chamber upstream of an orifice through which the air is vented to atmosphere.Type: GrantFiled: June 11, 1999Date of Patent: January 30, 2001Assignee: Delaware Capital Formation, Inc.Inventors: William J.

Patent number: 5884809Abstract: A dispensing system (20) for drawing fuel from a storage tank (22) to a nozzle (44). The system includes an above-tank suction pump (26) which draws fuel from the tank. The fuel is discharged from the suction pump into a vertically aligned air separator (38) so as to produce a fuel stream that is substantially free of air. The fuel stream is discharged from the air separator to a flow meter (30) and the nozzle through a fuel shutoff valve (46). The open/closed state of the fuel shutoff valve is controlled by a control actuator (48) based on the differential processor across the air separator. Should this differential pressure drop below a given level, the fuel shutoff valve is closed to prevent the system from inadvertently supply a fuel stream with an unacceptably high air content. Gaseous fluid removed by the air separator is supplied to an air eliminator (40). The fuel components of this fluid stream are removed in the air eliminator and returned to the suction pump.Type: GrantFiled: May 5, 1997Date of Patent: March 23, 1999Assignee: Delaware Capital Formation, Inc.Inventors: Gregory P. Wood, Michael D. Walters, Scott M. Olson

Patent number: 4927056Abstract: In one embodiment, the high viscosity fluid to be metered and dispensed is oil that is pumped at a low flow rate, in the range of one quart per minute. A positive displacement pump obtains the oil from a tank and pumps the oil to an air eliminator. A volumetric meter is downstream of the air eliminator and receives the oil therefrom via a hydraulic system line. An electronic detector/pulser produces signals based upon the flow of oil through the meter. In a working embodiment, 1,000 pulses represent one quart of oil. These pulses are applied to a controller which includes an adjustable calibration circuit that corrects for system characteristics in order to dispense a "legal" quart of oil to a customer. The controller has an input device and a comparator that enables the controller, after being programmed, to dispense, for example, two quarts of oil.Type: GrantFiled: May 22, 1987Date of Patent: May 22, 1990Assignee: RSL Industries, Inc.Inventor: Richard S.

Patent number: 4382527Abstract: In a system for dispensing weighed or counted articles, articles are fed from a supply hopper by a vibratory conveyor to maintain a controlled level of articles in a bowl-shaped feeder hopper. In a weigher embodiment, articles are initially discharged from the feeder hopper through two discharge openings into an accumulator bucket. A weighing unit monitors the weight of articles in the bucket and signals a door to close one of the discharge openings as the weight of articles in the bucket begins to approach a predetermined weight. The weighing unit subsequently signals the feeder hopper drive to slow its feeding action as the weight of articles in the bucket more closely approaches the predetermined weight. The feeder hopper discharge openings are arranged near each other at locations where the door-controlled opening will provide a rapid, bulk feed of articles, while the other opening will provide a single-file trickle feed.Type: GrantFiled: December 3, 1979Date of Patent: May 10, 1983Assignee: Automated Packaging Systems, Inc.Inventor: Bernard Lerner
