Patent number: 10583448Abstract: In an example, an electrostatic spray module includes a base unit formed of a sturdy, rigid, liquid impermeable, electrically insulative material and a cover formed of a sturdy, rigid, liquid impermeable, electrically insulative material and sized for covering the base unit. The base unit and the cover configured for mating engagement together so as to form a liquid impermeable, electrically insulative, protective enclosure when the module is in a closed state to keep the internal components clean and dry and prevents high voltage shorting and prevents leakage of current by inhibiting a high voltage from establishing a return path to ground. The spray module includes a quick access latch and gasket system—with no tools required to open for maintenance. The module includes integral place holders for components including air supply manifold and variable voltage supply to provide a selectable high voltage level to accommodate various spraying application.Type: GrantFiled: June 20, 2017Date of Patent: March 10, 2020Assignee: Progressive Grower Technologies, Inc.Inventor: William J. Hartman

Publication number: 20200045952Abstract: Examples described herein include a transportable agricultural spray system that may comprise a transportable sprayer with one or more spray nozzles to emit one or more fluid sprays while transported through air in a first direction. A first air-permeable panel may be positioned adjacent the transportable sprayer substantially outside the one or more fluid sprays to extend over an area transverse to the first direction across the one or more fluid sprays. In some examples, the first air-permeable panel may be positioned in the first direction in relation to the one or more fluid sprays. Other examples may include a second air-permeable panel positioned adjacent the transportable sprayer at least substantially outside the one or more fluid sprays to extend over and an area across the one or more fluid sprays transverse to the first direction, wherein the second air-permeable panel is positioned opposite the first direction in relation to the one or more fluid sprays.Type: ApplicationFiled: August 9, 2018Publication date: February 13, 2020Applicant: PROGRESSIVE GROWER TECHNOLOGIES, INC.Inventor: William J.

Patent number: 6227466Abstract: An electrostatic spray module for applying agricultural liquids such as a pesticide to crops where, externally to the spray module the number of connections is reduced to three, one for the liquid pesticide, one for compressed air and one for a low voltage signal. Internally to the spray module, the low voltage is converted to a high voltage signal, which is, along with the pesticide and the compressed air delivered to one or more electrostatic spray nozzles using only two electrically conductive pipes, a gas delivery pipe and a liquid delivery pipe. The nozzles fit into the gas delivery pipe and draw the compressed air through gas channel openings in the side of the nozzles. The gas delivery pipe doubles as the means to delivery the high voltage signal to the nozzles. Each nozzle has a liquid feed from the liquid delivery pipe, which carries ground voltage, maintaining the liquid at ground voltage. The grounded liquid merges with the compressed air in the nozzles to form an atomized liquid.Type: GrantFiled: November 9, 1999Date of Patent: May 8, 2001Inventors: William J. Hartman, Roger G. White

Patent number: 5188854Abstract: A process for producing a seafood analog product comprising the steps of mixing chunks of a natural fish and a binder to coat the surfaces of the chunks with the binder, the chunks being frozen and maintained in a frozen state throughout the mixing, forming a quantity of the coated chunks to a desired shape, the chunks being frozen and maintained in a frozen state throughout the forming, subjecting the formed, binder-coated chunks to an elevated temperature to raise the internal temperature of the chunks to a predetermined level sufficient to cook the chunks and set the binder, and subjecting the formed and cooked binder coated chunks to pasteurization. Subsequent to pasteurization, the product is immediately cooled for extended shelf life.Type: GrantFiled: September 18, 1991Date of Patent: February 23, 1993Assignee: Tyson Holding CompanyInventors: William J.

Patent number: 4684834Abstract: An electromagnetic motor apparatus is used for converting electrical energy into rotary motion and includes a housing having a crankshaft rotably mounted therein. A plurality of stators form cylinders and are mounted onto the housing. A plurality of armatures form the pistons and are movably mounted to slide in the stators. Each armature has an armature piston rod connected to each armature and to the crankshaft for turning the crankshaft responsive to the movement of the armatures in a timed sequence. A distributor is operatively connected to the crankshaft for distributing electrical energy applied to the distributor from the distributor to the stator windings. The distributor has at least one pair of electrical contacts moving in a liquid bath responsive to the rotation of the crankshaft to direct electrical energy to the stator in timed sequence so that electrical arcing is reduced in the distribution of the electrical energy in an electromagnetic motor.Type: GrantFiled: January 2, 1986Date of Patent: August 4, 1987Assignee: Robert W. DelongInventor: William J. Hartman, Sr.
