Patent number: 4707140Abstract: A feed mixer for cattle and other livestock. The mixer includes a mixing tank with two main chambers on either side of an auxiliary chamber. Rotors in the general shape of paddle wheels are mounted in each main chamber. The mixing paddles of each rotor are elongated and extend between corresponding sections of the rotor with the axis of each paddle offset from the rotational axis of the rotor by about 15 degrees. In this manner, the mixing paddles give a slight axial component of movement to the feed as it is being mixed. The paddles of each rotor are preferably operated out of phase with those of the other rotor wherein portions of the feed are alternately transferred across from one main chamber to the other. This transferring effect combined with the axial component of movement imparted in each main chamber by the mixing paddles results in a unique mixing pattern wherein feed is moved between and along the main chambers substantially in a spiral 8 path.Type: GrantFiled: September 29, 1986Date of Patent: November 17, 1987Assignee: Mohrlang Manufacturing, Inc.Inventor: Harry Mohrlang

The mixing member may be rotated at a first speed of rotation effective to mix materials within the mixing chamber without discharging from the outlet means. The mixing member is also rotatable at a second speed of rotation effective to discharge the charge or batch of material through the outlet means after it has been treated during the initial mixing step. The rotation of the mixing member at a higher rate of speed at the second speed of rotation effects discharge through the outlet means by centrifugal force.Type: GrantFiled: February 4, 1977Date of Patent: June 17, 1980Assignee: Protein Foods (U.K.) LimitedInventor: Kenneth F.

Patent number: 4193430Abstract: A system for filling generally cylindrical barbell weight shells with a relatively viscous slurry of cementitious material comprises a roller conveyor which transports a plurality of carriers each supporting a plurality of barbell weight shells thereon through a plurality of stations. At a lubricating station, the exterior of the shells is coated with a light film of oil to facilitate subsequent cleaning thereof. At a filling station, a dispensing hopper having a plurality of downwardly projecting nozzles dispenses the cementitious slurry into the shells. Each of the carriers is positioned beneath the hopper, the shells thereon are aligned with the nozzles, and a lift table lifts the shells off of the roller conveyor into engagement with the nozzles. Vibratory and agitator devices induce the flow of the slurry from the hopper into the shells under the influence of gravity.Type: GrantFiled: October 18, 1977Date of Patent: March 18, 1980Assignee: Diversified Products CorporationInventors: Forrest H. James, Jr., Ira J. Silberman

Patent number: 4185927Abstract: In a mixing machine having a cylindrical mixing chamber in which a centrifuging agitator coaxially rotates on a horizontal axis, an inlet duct for dry mix material and liquid curves downwardly and towards one end wall of the chamber and an outlet duct for mixture curves downward and away from said end wall. Material to be mixed thus enters the chamber in substantially horizontal flow through an inlet port in said end wall, all portions of said port being spaced radially inwardly from the cylindrical chamber wall and below the level of the chamber axis. Mixture leaves the chamber in substantially horizontal flow through an outlet port wholly spaced below the inlet port and extending down to the level of the bottom of the chamber. Centrifuging action maintains a pressure difference between the ports that assures fast movement of materials through the mixing chamber to prevent plugging of the machine when mashed potato mix is used.Type: GrantFiled: October 23, 1978Date of Patent: January 29, 1980Assignee: Karma Division of Brandt, Inc.Inventor: Raymond E.

Patent number: 4152079Abstract: Apparatus for dispensing thick liquid-like products in comparatively small amounts while simultaneously mixing therewith an appropriate amount of a selected one of several liquids. An instant and thorough mixing is accomplished by directing the product into a spinning cup while at the same time directing thereinto the selected liquid. The cup has a side wall close to but spaced from the wall of a dispensing passage in which the cup is located thereby forming a narrow annular mixing passage therebetween. The cup wall has orifices therein through which the product material and the liquid are flung by centrifugal force, the liquid and product being instantly and thoroughly mixed by this action and by spinning travel through the mixing passage.Type: GrantFiled: September 14, 1977Date of Patent: May 1, 1979Inventor: Edward D.
