Abstract: A volumetric feeder made of a plurality of independent feeder elements 20a, 20b. Each of the feeder elements is provided with a stationary portion 21 and a movable volumetric measure 22 that moves back and forth in the stationary portion 21. Each movable volumetric measure is provided with a measure portion 23 for accommodating a predetermined volume of powdery or granular material. The movable volumetric measure in the feeder elements are capable of moving independently of one another between a charging position at which the measure portions 23 coincide with charging apertures 24 of the stationary portion 21, and a discharging position at which the measure portions 23 coincide with discharging apertures 26 of the stationary portion 21.

Abstract: A method and device are disclosed for metering a predetermined amount of a particulate substance in a reliable and exact manner. The claimed invention avoids crushing or packing the material to be metered, and can be utilized with fine particulate substances with poor flow properties such as agglomerates as well as with coarser granulates. The substance to be metered is gravity-fed by a tumbling reservoir and inlet through an unbroken and uninterrupted inflow path which comprises two parts, one which is coaxial with the rotational axis, and a second which is inclined relative to the rotational axis. After passage through the inflow path, the substance enters the metering chamber which accurately and uniformly measures the desired quantity of substance, which then exits through the outflow path. The design of the device prevents inaccurate metering through overfilling or premature emptying of the metering chamber.

Abstract: Fluid dispensing apparatus for dispensing small precise metered quantities of fluid, for example in a semiconductor manufacturing process, comprises two metering chambers disposed in series. Each metering chamber has an associated piston rod and fluid is dispensed therefrom alternately. Twice the volume of fluid is displaced from the upstream metering chamber so that when it dispenses fluid at the same time it can refill the second downstream metering chamber.

Abstract: A two-part dispenser for attachment to the bottom of a cylindrical container for dispensing a pre-calibrated amount of powdered or granular product from the container by twisting or rotating one part of the dispenser with respect to the container. The dispenser comprises a generally cup-shaped member adapted to engage the bottom of the container in fixed relationship therewith and a chambered member that fits within the cup-shaped member and can be rotated with respect to the cup-shaped member to dispense product.

Abstract: A plating chemical replenishment system is described having a tank for supporting a chemical solution used in a plating fluid, a container having a pre-determined volume, a first valve for selectively coupling the chemical solution from the tank to the container to form a pre-determined volume of the chemical solution within the container, and a second valve for selectively dispensing the pre-determined volume of the chemical solution from the container to a plating fluid reservoir. Also disclosed is a method of dispensing a plating solution to a plating fluid reservoir, comprising the steps of forming a pre-determined volume of the plating solution; and dispensing the pre-determined volume of the plating solution to the plating fluid reservoir.

Abstract: A novel container called a tire tube is made from whole, used tires. They are first turned inside out or inverted. Several tire tubes may be connected together side by side with holes aligned sing fasteners such as screws. With the ends sealed the tire tube may be used as a container for toxic substance storage, or sand to act as a highway bumper. With the ends left open the tire tube may be used as a conduit, or a culvert. Supported to allow rotation at a slight angle to the horizontal and with the higher end being fed material, the rotating tire tube tumbles the material to the exit end. With rock added, the result of tumbling is a pulverizing action. By adding organic material and keeping it moist the rotating tire tube becomes a continuous-action composter.

Abstract: A dispenser for pulverulent materials includes receptacle for receiving a container holding the material to be dispensed. A valve body defining metering cavities is mounted in the valve body. A gate also mounted in the valve body includes a first portion for selectively locking flow into the metering cavities and a second portion for selectively blocking flow exiting the metering cavities, with a desired quantity of material being trapped between the gate portions, for subsequent release.

Abstract: A device is provided for controlled dispensing of a measured quantity of fluid from a flexible wall container. The device has a chamber adapted to hold a measured quantity of fluid when the container is inverted and righted. This fluid is then dispensed from the chamber through a conduit in direct response to a force exerted on the flexible wall of the container.

Abstract: An apparatus wherein an upper housing fixedly secures an aligned series of dispensing tubes. The dispensing tubes include an upper opaque portion overlying a conical lower transparent portion. The upper portion includes a first valve to dispense food components into the lower portion, with the lower portion including a second valve tube to permit directing of the food onto individual plates by patrons of the apparatus. The organization includes a catch tray underlying a support grid to contain food components having fallen through the support grid. The invention may further include a modified dispensing tube housing defining an enclosed conduit operably associated to an air conditioning duct to provide cooling and chilling of food components contained within the dispensing tubes.

Abstract: Liquid dispensing apparatus is disclosed having at least one liquid dispensing chamber and an associated prefill chamber with displacement mechanism for transferring liquid therefrom to the dispensing chamber.

Abstract: A plurality of members are arranged in side by side relation to form a plurality of horizontal rows, vertically stacked in a vertical drier. Movable means are associated with selected rows of the members and are movable to form a floor to separate one part of the drier from another part so as to maintain loads of material moving through the drier separate as the material is being dried. Means are provided to actuate the movable means in a predetermined sequence to stepwise form a floor from the top to the bottom of the drier whereby loads of material in the drier are maintained separate as they are moved through the drier.
