Patent number: 7806948Abstract: A filter system for ambient air to remove airborne particulates in air that is to be used for engine operation. A filter media that is pervious to air and impervious to the particulates may be coupled to a filtered air chamber, which in turn may supply filtered air to the engine's air intake system. In various embodiments, the engine's air intake may be used utilized to draw air through the filter media into the filtered air chamber. An pressurized gas pulsing system may be used to periodically urge reverse airflow through the bag walls to maintain the permeability of the walls to the clean air.Type: GrantFiled: November 13, 2007Date of Patent: October 5, 2010Assignee: Johnson Crushers InternationalInventors: James Donald Brock, Gary Heeszel, Jon Juhlin, Tom Furrer, Robert Carnes

Patent number: 7143968Abstract: A rock crushing plant including rock crushers, screens and conveyors. The assembly is modularized whereby major components and associated support structures are organized into movable modules that are independently movable from site to site over public roadways. The modules are equipped with appropriate support wheels for traveling and stabilizing jacks for stabilization of the modules at a rock crushing site. Modifications are made to certain of the components to satisfy road height and width restrictions, e.g., folding conveyors. Each module is preferably equipped with its own power plant.Type: GrantFiled: May 4, 2005Date of Patent: December 5, 2006Assignee: Johnson Crushers InternationalInventors: James Donald Brock, Gary P. Heeszel, Jeremiah West, Lawrence Calvin Olsen, Robert W. Carnes

Patent number: 4103350Abstract: Drum mix asphalt plant apparatus connected to a fiber filter dust collector for removing dust and other light particulate matter produced by operation of the drum mixer. Asphalt material is added to the drum mixer in a manner to minimize smoking of the asphalt material due to high temperature within the mixer, and the resulting dust and other fine particulate matter evolved from aggregate material within the drum mixer is withdrawn and collected in a fiber filter dust collector system such as a baghouse. The collected dust is returned to the drum mixer to be coated with asphalt material therein, so that the returned dust becomes admixed with the asphalt aggregate contents of the drum mixer.Type: GrantFiled: March 22, 1977Date of Patent: July 25, 1978Assignee: Astec Industries, Inc.Inventors: James Donald Brock, Erbie Gail Mize

Patent number: 4033458Abstract: Shredded scrap is conveyed from a heat generating automobile shredder to one end of a horizontal tumbling drum and is caused to move in one direction through the drum as it tumbles. An air stream which has aspirated heat generated by the shredder, and carrying particulate material removed from the scrap in the shredder, is directed by ductwork to the opposite end of the tumbling drum where the air and particulate matter move in counterflow through the tumbling scrap to remove additional particulate material therefrom as the shredded particles are being showered through the air stream. The particulate material in the air stream emerging from the tumbling drum is separated out by a cyclonic separator. A bypass air stream duct with an adjustable valve bypasses some of the air stream around the tumbling drum to control the velocity of the air stream through the tumbling drum and thus to control the size of the particulate material removed from the scrap by the counterflow air stream.Type: GrantFiled: March 19, 1975Date of Patent: July 5, 1977Inventors: Julius L. Chazen, James Donald Brock

Patent number: 4005979Abstract: A multiple stage oven for heating a product such as carpet or the like, which serially moves through each stage to be heated. Each stage of the oven includes a fuel burner for heating air within the stage, and a fan for recirculating the heated air in the stage for impingement onto a carpet product moving through the stage. A portion of the heated air within each stage is drawn from that stage and supplied to a serially preceding stage. The volume of air withdrawn from the last stage in the serial arrangement, and also the volume of make-up air admitted to the first stage thereof, does not exceed the sum of the fuel combustion products within the zones and any moisture or other substance evaporated or evolved from the carpet in each of the heating zones.Type: GrantFiled: July 3, 1975Date of Patent: February 1, 1977Assignee: Astec Industries, Inc.Inventor: James Donald Brock

Patent number: 3991482Abstract: Apparatus and method for removing moisture from textile products which are sufficiently porous to permit a substantial flow of heated fluid through the product. Two separate drying regions are provided through which a web of textile product is serially moved. The textile product divides each drying region into a pair of drying zones, and a differential pressure of heated air is maintained on opposite sides of the textile product in each of the heating regions to maintain a flow of heated air through the textile product. The wet textile product first passes through an initial heating region for flowthrough exposure to air heated to a temperature exceeding the temperature at which the dry textile product is damaged, for evaporation of unbound moisture without damaging the textile product. The textile product then passes through a subsequent heating region for flow-through exposure to recirculating air at a temperature which is nondamaging to the textile product.Type: GrantFiled: February 24, 1976Date of Patent: November 16, 1976Assignee: Astec Industries, Inc.Inventors: James Donald Brock, Erbie Gail Mize
