A method of fabricating plastic products having a preselected color, comprising preparing a dispersion of pigment of the preselected color in cottonseed oil; supplying a preselected plastic resin for the product to be fabricated to a process machine having a rotating screw; furnishing the dispersion to the process machine at a position adjacent to threaded portion of the rotating screw; and blending the dispersion and the resin by rotating the screw.

Plastics coloring using cottonseed oil-based liquid color compositions

A liquid colorant for use in molding or extruding plastic products comprises pigment dispersed in cottonseed oil.

Cottonseed oil liquid color composition and method

A receiver having a horizontally elongated chamber within a housing, the chamber having a convex triangular cross-section and a dump flap defining a bottom vertex of the triangular cross-section, with a horizontal air/vacuum resin material inlet connecting to the chamber, and a horizontal air/vacuum outlet leading from and connected to the chamber.

Vacuum actuated receiver having low profile

Method and apparatus for pneumatically conveying granular resin material and controlling such conveyance includes a sensor associated with granular plastic resin material receiver with the sensing vacuum level thereat and a microprocessor adjusting vacuum pump speed based on vacuum level sensed at the receiver.

Resin delivery method and apparatus using multiple sensors for optimal vacuum pump operation

A controlled, variable speed vacuum pump with a flow limiter connected to the suction head of the vacuum pump conveys granular plastic resin material from a supply to receivers retaining and dispensing resin when needed by a process machine.

Flow limiting and variable frequency drive apparatus for limiting flow to selected level

Cottonseed oil based liquid color composition and plastics coloring method using the same

A vacuum pump with a first flow regulator connected to the suction head of the vacuum pump for conveying granular resin material from a supply to receivers retaining and dispensing the resin when needed by a process machine and a second flow regulator controlling and limiting to a maximum value vacuum flow through a conduit carrying auxiliary additives to the receivers.

Plural air flow regulator delivery apparatus and method

A method for temporary storage of granular material in a receiver having a horizontally elongated chamber within a housing, the chamber having a convex triangular cross-section and a dump flap defining a bottom vertex of the triangular cross-section, with a horizontal air/vacuum resin material inlet connecting to the chamber, and a horizontal air/vacuum outlet leading from and connected to the chamber.

Storage method for resin using low profile receiver

Apparatus for air flow limiting comprise a vertically oriented tube, a sail assembly positioned in the tube and moveable therewithin responsively to air flow through the tube to limit rate of air flow through the tube and halt air flow through the tube upon air flow rate through the tube exceeding a preselected value, and a moveable stop for adjustably changing the length of travel of the sail assembly thereby changing the maximum amount of air flow.

Method for adjustably restricting air flow and apparatus therefor

Method for pneumatically conveying granular resin material and controlling such conveyance includes a sensor associated with granular plastic resin material receiver with the sensing vacuum level thereat and a microprocessor adjusting vacuum pump speed based on vacuum level sensed at the receiver.

Multiple sensor resin delivery method for optimizing vacuum pump operation

Method and apparatus for drying granular resin material by drawing vacuum over heating resin material in a vessel, while periodically purging the vessel with the material therein with dry air and bathing the vacuum dried material with dry air until furnished to a processing machine.

Vacuum drying method and apparatus

A method of fabricating plastic products having a preselected characteristic, comprising preparing a dispersion of at least one additive contributes the preselected characteristic in cottonseed oil; supplying a preselected plastic resin for the product to be fabricated to a process machine having a rotating screw; furnishing the dispersion to the process machine at a position adjacent to threaded portion of the rotating screw; and blending the dispersion and the resin by rotating the screw.
