Patent number: 5297745Abstract: A more even distribution of manure during spreading, a more efficient pickup of loose and gummy material, a more efficient pickup of manure in irregular feedlots, and avoidance of spillage of manure during transport are accomplished by employing a method of handling manure from a feedlot including providing a tank with a rear pickup mechanism. The tank and attached rear pickup mechanism rotate fore and aft by means of a pintle attached to a frame. The tank is so placed relative to the pintle that, as the frame is raised relative to the wheels, the tank first tilts backward and then forward, preventing overspills. The tank is partially filled with water and then the tank and pickup mechanism rotate to keep the mechanism in contact with the area to be cleaned. The mechanism then deposits manure from the area in the tank. A pump mixes the manure with the water to form a slurry and discharges the slurry from the tank.Type: GrantFiled: December 23, 1991Date of Patent: March 29, 1994Inventor: Owen Vinyard

Patent number: 5295629Abstract: A vertical type grain-milling machine has a perforated bran removing cylinder arranged vertically with respect to a machine frame; a main shaft which is rotatably provided within the perforated bran removing cylinder; and a milling roll and a screw roll which are in abutment with each other and which are mounted on the main shaft, the milling roll being associated with a grain discharging section and the screw roll being associated with a grain supplying section. The perforated bran removing cylinder is surrounded by an air in-take frame which has a large number of through-holes for causing in-flowing air to have a downward component of orientation. The discharging of the bran externally of the machine is enhanced and the adherence of bran onto the inner wall of the air in-take frame and the perforated bran removing cylinder is prevented.Type: GrantFiled: June 9, 1993Date of Patent: March 22, 1994Assignee: Satake CorporationInventors: Toshihiko Satake, Satoru Satake, Nobuhiro Matsumoto, Hiroyuki Fukumitsu

Patent number: 5289979Abstract: An arrangement for discharging hard material from the grinding head of a meat grinder. The hard material is passed through openings formed in the meat grinder orifice plate, and collected in a collection cavity defined by a cup member. A hard material discharge auger is located within the collection cavity, and is rotatable with the feed screw of the grinder. A restricting arrangement is provided for building up back pressure within the collection cavity, which minimizes the amount of usable soft material which passes into the collection cavity. In one form, the discharge auger extends through the collection cavity and into a discharge passage defined by a discharge tube. The auger has an outside diameter only slightly smaller than the diameter of the passage, so that the auger essentially defines a rotating flow path through which the hard material is discharged. In another form, the restricting arrangement includes a tapered passageway and a resilient diaphragm having an aperture therethrough.Type: GrantFiled: October 17, 1991Date of Patent: March 1, 1994Assignee: Weiler and Company, Inc.Inventor: Nick J. Lesar

Patent number: 5279463Abstract: The method for treating materials in liquids involves passing them with the liquid through a processing gap formed by a flow passage whose walls are closely spaced and move relative to one another transversely to the direction of flow, thereby producing "supra-kolmogoroff" mixing eddies in the gap, and at the same time applying ultrasonic longitudinal pressure oscillations that reverberate between the two closely spaced surfaces into the gap transversely to the direction of flow from transducers mounted on one wall, thereby producing "sub-Kolmogoroff" mixing eddies therein. The method is capable of rapidly producing relatively thick slurries of sub-micrometer particles that otherwise can take several days in conventional high shear mixers and ball or sand mills, or of rapidly dissolving difficultly soluble gases and powders into liquids.Type: GrantFiled: August 26, 1992Date of Patent: January 18, 1994Inventor: Richard A. Holl

Patent number: 5263855Abstract: An annular passage arrangement for a pulverizer includes vertically extending inner and outer passage walls which define a "boxed" annular passage. The annular passage space has an inlet for receiving flow from an air plenum and an outlet for vertically channeling the flow into a pulverizing zone. The annular passage is divided by vanes having a tapered end at the inlet end of the passage and an outlet end located at the passage outlet. The outlet end of each vane extends at an acute angle to the horizontal and the tapered end of each vane is vertically oriented within the annular passage. This vane orientation reduces pressure drop as the plenum air is fanned up into the pulverizing zone. Flow contouring plates below the passage inlet reduce flow disturbances and create a more uniform flow pattern up and into the passage inlet.Type: GrantFiled: March 11, 1993Date of Patent: November 23, 1993Assignee: The Babcock & Wilcox CompanyInventors: George B.
