Patent number: 5992689Abstract: Many types of processors of particulate materials operate more efficiently when they receive the particulate material in a steady stream. Most feeders tend to discharge in pulses. A hopper is interposed between the feeder and the processor. Surges in the feed rate are accumulated in the hopper, and lapses in the feed rate are compensated by the propensity of the hopper to discharge at a constant rate. Initiation of hopper flow is accomplished by use of a trap door. Mismatch between average feeder output rate and hopper discharge rate is corrected by use of an adaptive hopper having an outlet the size of which is slowly altered to maintain a constant amount of material in the hopper. A bypass hopper is used to control extremely variable input flow rates.Type: GrantFiled: November 4, 1996Date of Patent: November 30, 1999Assignee: Jr Johanson, Inc.Inventor: Jerry R. Johanson

Patent number: 4009906Abstract: An improved metering gate for metering fluid materials discharged from a hopper of the type including a vertically oriented discharge opening. The metering gate is characterized by a pair of closure panels arranged in coplanar relation, a drive mechanism including a plurality of rams connected with said closure panels for displacing the closure panels in opposite directions along a pair of aligned linear paths traversing the opening, and a motion balancing mechanism interconnecting the panels for equalizing the distances through which the panels are displaced by said drive mechanism, and a lag-elimination mechanism for eliminating lag in the displacement imparted to the opposite ends of each panel of said pair, whereby each portion of each panel of said pair of closure panels is displaced through a distance equal to the distance through which any other portion of either panel of said pair of closure panels is displaced by said drive mechanism.Type: GrantFiled: September 15, 1975Date of Patent: March 1, 1977Assignee: American Carrier Equipment, Inc.Inventors: Philip J. Sweet, Buck C. Hamlet, David L. Sweet

Patent number: 4004700Abstract: A belt feeder gate for use in self-unloading ships of the type in which the hold of the ship is provided with a hoppered bottom including a plurality of hoppers overlying an unloading conveyor belt moving lengthwise of the ship. Each open hopper bottom is closed by a gate comprising two wheeled gate sections which are movable relative to each other along stationary tracks in a horizontal plane and in a direction laterally of the direction of travel of the underlying unloading conveyor belt. The respective longitudinally opposite wheeled ends of the respective gate sections project in underlying relation to longitudinally spaced "hog ridges" defined by the walls of adjacent hoppers, each "hog ridge" being an inverted V-shaped hollow space defined beneath two upwardly converging oppositely longitudinally inclined walls of two longitudinally adjacent discharge hoppers.Type: GrantFiled: December 22, 1975Date of Patent: January 25, 1977Assignee: Allis-Chalmers CorporationInventor: Robert M.
