Abstract: A microingredient dispenser for delivering a continual supply of feed additives from supply cartridges to animal feed. The dispenser includes a frame, first and second hoppers, first and second dispensing stations, a plunger drive mechanism, first and second ingredient receiver couplings, first and second cartridge retainer mechanisms, and control means for coordinating the movement of bar-coded cartridges and a drive mechanism.

Abstract: Liquids are segregated into separate chambers within a common container. The chambers are formed by fabricating the container in an hourglass design thus dividing it into upper and lower segments. The chambers are serviced by separate pumps which draw the constituent liquids independently and deliver them through a common outlet. The chambers are isolated from one another by inserting the pump servicing the lower chamber through the upper chamber and fitting it snugly into the waist of the hourglass. The pumps servicing the upper and lower chambers move in tandem and are fixed together by a common pump head. The pump head also serves as the outlet through which the constituent liquids are delivered. Liquid is delivered in fixed quantities from the lower chamber via an elongated pump mechanism. Liquid is delivered in adjustable quantities from the upper chamber via a modified pump design.

Abstract: The present invention provides improved method and apparatus for the transfer and delivery of very high purity chemicals for use in semiconductor production and similar processes. By employing a series of vessels arranged in parallel, a vacuum system to draw chemical from one or more bulk sources into the vessels, and a pressure system to deliver chemical under pressure from the vessels, chemicals can be easily delivered from any bulk source to one or more end-users. The use of a vacuum system to draw chemicals through sealed conduits eliminates the need for pumps which are a source of both maintenance problems and contamination in the system. Multiple vessels provide for a variety of flow options, which include continuous and uniform chemical delivery to the end-users, recirculation and regular filtration during periods of low use, and built-in redundancy to avoid system shut down if there is a component failure. Computer controlled process systems provides system flexibility and full automation.

Abstract: A dispenser for simultaneously dispensing and mixing a pair of fluid products such as chemically reactive resins, from a pair of axial adjacent front and rear chambers. A piston is mounted within each of the chambers and is moveable with respect to the hollow interior of the respective chamber for dispensing the fluid product therefrom.

The rear chamber has a relatively tight sliding fit within the front chamber so that a partial vacuum is formed within an annular space which forms between the two pistons as they move apart upon discharge of the two products to produce a "suck back" effect on product remaining in the discharge nozzle.
