Abstract: Determining a maximum dispensing efficiency of a dispensing point in a fuel dispenser and determining if a dispensing point has a blockage and/or a performance problem if the maximum dispensing efficiency is less than expected. The maximum dispensing efficiency is calculated by determining the dispensing events exhibiting the lowest time for dispensed volume from a set of volume and time pair measurements for the dispensing point. The dispensing events exhibiting the lowest time for dispensed volume that are used to determine the maximum dispensing efficiency are taken from dispensing events where the amount of dead time, the time between the activation of a fuel dispensing event and the engaging of a nozzle and the time between the disengaging of the nozzle and the deactivation of the dispensing event, and customer or pre-pay transaction controlled reduced flow rates are minimized.

Abstract: An apparatus for agitating ice cream in an ice cream vending machine including a screw member rotatably disposed on an inner lower side of a canister, a worm wheel disposed in contact with an upper end of the screw member, rotatably driven by a rotational movement of the screw member, and an agitating member, a lower end of which contacts the worm wheel, and an upper end positioned at an inner upper side of the canister. The agitating member agitates ice cream particles filled in the upper and lower portions of the canister evenly by being resiliently vibrated upward and downward by rotational movement of the worm wheel. Accordingly, by evenly agitating ice cream particles at upper and lower portions of the canister, the bead-shaped ice cream particles are prevented from attaching to each other.
Abstract: A granular material spreader is adapted for towing behind a yard tractor. A frame upports an inverted cone which is sized to contain a supply of granular material for distribution. The bin sweep rod is carried adjacent to the inside surface of the cone, and turns a drive spring. The drive spring drives a helix, which rotates about the bin sweep rod, driving the granular material toward the narrow base of the cone. Should the helix become jammed, the drive spring snaps past the helix, rather than risk damage by forcing its movement. A bin sweep drive wheel is also driven by the revolution of the bin sweep. Movement of the wheel against the an upper portion of the outside surface of the cone moves the bin sweep rod and helix in a circular path about the inside surface of the cone. A valve at the base of the cone allows granular material to drop into a housing which defines slots about portions of its perimeter.
Abstract: A single-piece piston and drive assembly for use in a motor-actuated pump to meter a predetermined amount of lubricant or other liquid. The drive assembly includes a rotatable drive shaft, an eccentric cam insert, a cam rod, and a rocking beam. The rocking beam is coupled to the piston, the cam rod shaft, and a biasing mechanism. When the drive shaft is rotated, movement of the cam rod shaft causes the rocking beam to pivot and move the piston along a stroke to dispense the liquid. The piston operates in association with a flow adjustment stem that regulates the amount of liquid metered by the pump, and a valve assembly for evacuating the liquid from the pump chamber into and through an outlet fitting.Also provided is a flow volume indicator for use in a pump for indicating the amount of liquid being discharged. The flow volume indicator has a main body with an annular side wall, flexible base wall, and a knobbed pointer that is inserted into a bore of the pump body and coupled to the flow adjustment stem.

Abstract: A cleanser feeding mechanism has a cleanser housing portion, a cleanser feeding member for feeding a cleanser housed in the cleanser housing portion, and a synchronous motor for applying a drive force to the cleanser feeding member, and feeds and amount of cleanser corresponding to the number of revolutions of the synchronous motor. A cleanser feeding amount-setting unit sets an amount of cleanser to be fed from the cleanser feeding mechanism. A driving unit applies an AC source voltage of an AC power source to the synchronous motor. A counter counts the number of cycles of the AC source voltage from a timing at which the AC source voltage is applied to the synchronous motor. A reference cycle number-setting unit sets a total cycle number of the AC source voltage which corresponds to a cleanser amount set by the cleanser feeding amount-setting unit.

An actuating medium for rotating the ball valve between the first and second positions, an elastic member for usually urging the ball valve at the first position, and an oscillating element capable of contacting with the radial protrusion in the course of rotation between the first and second position in order to be oscillating.
Abstract: An apparatus in which particles are dispensed from an open ended chamber of a container into a transport adapted to move the particles therefrom. The apparatus prevents the bridging and caking of particles in the chamber. A member, positioned in the chamber of the container in the region of the open end thereof, is in engagement with the transport. The member is resiliently coupled to the container and agitated as the transport moves the particles. This causes the springs resiliently coupling the member to the container to vibrate. As the springs vibrate, bridging and caking of the particles is prevented and the particles are dispensed from the open end of the chamber in the container.
Abstract: The metering device for powdered material comprises a storage container (10) for the powdered material and a discharge opening in the bottom of the storage container which is opened and closed, respectively, by a closing mechanism (12). The powdered material flows through the discharge opening into a drawing cup (13). In order to obtain a defined bulk density of the powdered material in the drawing cup (13), a vibration mechanism (14) imparts vibrations to the metering device when the discharge opening (11) is open. The closing mechanism (12) can be designed in the manner of a blade diaphragm, and in that case the closing mechanism (12) can be actuated by a grooved disk (17) which at the same time is a part of the vibration mechanism (14).
