John T. Farnsworth has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7290999
    Abstract: A die plate for an extruder is coupled directly to a fluid-driven motor on one side and to an extruder on the other side. Suitable fluid inlet and outlet passages are formed in the die plate to supply the motor with fluid and withdraw fluid. A cutter assembly includes a housing to receive the motor within and is coupled for rotation to an output shaft from the motor, so that in use blades mounted on the housing are caused to rotate into the path of extrudate and to sever it.
    Type: Grant

  • Patent number: 6440473
    Abstract: A composite consumable food product in the form of a section of an extruded strand of a first foodstuff impregnated into a second foodstuff. Prior to extrusion of the strand in a twin screw extruder, the first foodstuff is a liquid or a pasty consumable substance, such as a syrup, while the second foodstuff is a plasticized consumable substance, such as a cereal base. The first and second foodstuffs are preferably processed in separate sections of the extruder before a taste or flavor perceptible amount of the first foodstuff is introduced into and uniformly mixed with the second foodstuff prior to extrusion through a die. The resultant extruded strand is typically cut into sections to obtain the final product.

  • Patent number: 6268007
    Abstract: A process for manufacturing a composite consumable product by double extrusion, wherein a liquid or pasty consumable substance is prepared in a first section of a twin-screw extruder, a plasticizable consumable substance is cooked-extruded in a second section of the twin-screw extruder, wherein the first and second sections are separated dynamically, to provide at least one strand of a cooked-extruded mass that is cut into pieces. The liquid or pasty consumable substance is added to the cooked-extruded mass to provide pieces of a composite consumable product.

  • Patent number: 5538748
    Abstract: Fluid substances, particularly substances having differing viscosities, are combined and mixed by first segmenting a flow of a first fluid material to form a flowing segmented substance matrix containing a network of voids, such as by passing the flow through a plate having a plurality of passages therethrough and a second fluid substance is discharged into the segmented flow at a position which is substantially centrally disposed with respect to a cross-section of the segmented flow to combine the substance and additive, and then, the combined flow is mixed. The combined flow may be compressed and then mixed or may be compressed and then expanded prior to mixing. Additionally, a flow of a substance from a source such as an extruder may be partitioned into a plurality of streams and then, at least one of the streams is treated as specified above.

  • Patent number: 5443092
    Abstract: A valve device for restricting fluid flow has a hollowed piston member having a closed piston end wall and an open piston seat end. The piston end wall is integral with a second piston wall which extends to the piston seat open end which, in turn, opens into a chamber defined by the piston end wall and second wall. The piston second wall is positioned in slidable contact with a housing interior wall surface and has at least one aperture positioned therethrough for a fluid to flow in or out of the piston from the chamber so that upon the piston being reciprocated in the housing, when the piston seat end is seated in a seat integral with the housing, the at least one second wall aperture is confined by the housing interior wall surface to close the valve to fluid flow and so that when the piston is at a position displaced away from the seat, the at least one aperture is unconfined by the housing so that the valve is open to flow of fluid.

  • Patent number: 5165949
    Abstract: A free-standing die assembly, for use in the production of extruded products, which is mounted as a separate unit apart from the extruder in which product ingredients are processed. The die assembly includes a center plate having a die unit secured to one or more planar faces of the plate, with each of the die units having at least one die orifice in the outer surface thereof. Hot flowable dough processed in an extruder is carried via suitable tubing to the center plate from where it is distributed to the planar faces of the plate and into the die units, from which it is extruded through the die orifices in the die units. The die assembly may be modified to permit the production of coextruded product from the die orifices in the die units of the assembly. One or more of the die assemblies may be associated with a single extruder. In accordance with a preferred embodiment, die units are secured to opposing side faces of the center plate to provide a free standing, dual-faced die assembly.
