Abstract: An animal feed mechanism includes a manually operated slide valve interposed between a set of upper agitators and a set of lower screw conveyors. In some examples, two upper agitators are installed within a plastic funnel, and two lower screw conveyors are disposed within a metal auger housing. Each screw conveyor includes an auger driven by its own separate motor. Thus, there are two motors for rotating the two augers. The two motors can be energized individually to selectively rotate either auger or to rotate them concurrently. In some examples, a transmission coupling the two augers to the two agitators conveys power to rotate both agitators regardless of whether either one or both motor driven augers are operating.

Abstract: An improved procedure and apparatus for introducing liquids within a thermoplastic or thermoset production system are provided. Such an inventive apparatus comprises a storage tank for the desired liquid, a device which connects to a flow channel (such as a manifold or pipe) through which the target thermoplastic or thermoset composition is flowing, and a transfer line connecting the storage tank with the connecting device. The connecting device itself easily attaches and detaches to the flow channel through a spring-loaded or sliding-lock mechanism. Such a novel apparatus permits an ease in changeover from one liquid to another without the need for time-consuming cleaning and without complicated shut-off, removal, and replacement steps.

Abstract: An apparatus and method for mixing a dry chemical contained within a container. A probe is utilized to puncture an opening in the container and thereafter the probe is extended through the opening. A mixture or liquid is directed to and through the probe and, as the liquid or mixture exits the probe, the dry chemical is dissolved and mixed with the liquid or mixture. Thereafter, the resulting mixture gravitates downwardly through the opening in the container to an underlying tank. Associated with the tank is a concentration controller that is operatively connected to a pump that pumps the mixture from the tank to and through the probe. Effectively, the concentration controller periodically activates the pump so as to maintain the concentration level of the mixture in the tank within a pre-selected range.

Abstract: A blender for delivery of blend additives to a plastics extrusion device has a mixing chamber for reception of materials to be blended. Batches of blend materials are delivered to the mixing chamber from material supply bins via a weight hopper. Within the mixing chamber, a mixing screw circulates and mixes the blend materials prior to discharge through an outlet to an extrusion process line. As material is discharged, a material level sensor is uncovered and calls for a further batch of blend materials to be discharged from the weigh hopper into the mixing chamber. The screw has a pair of mixing blades of opposed pitch to direct material inwardly from outer ends of the screw towards a center of the screw located above the outlet. Excess material above process demand requirements is delivered to the outlet by the screw. This excess material is directed upwardly away from the outlet and recirculated towards outer ends of the screw and remixed without material within the mixing chamber.
