Patent number: 5353959Abstract: A system and apparatus for producing seasoned food products where seasoning is performed at individual packaging lines. The product is conveyed from the preparation area to a packaging area in an unseasoned condition. Upon reaching the packaging lines, which are disposed in packaging departments in the packaging area, the product can be selectively seasoned independent of other packaging lines. After seasoning, the product is packaged and prepared for delivery. At each packaging line, a volumetric feeder includes a feed head that cooperates with a tumbler having helical flights to produce continuous controlled product portions. A seasoning dispenser is positionable within the tumbler and can be adjusted to dispense a given weight of seasoning at a given rate, based on the amount of product passing through the tumbler, to obtain consistent seasoning levels and coverage.Type: GrantFiled: December 11, 1992Date of Patent: October 11, 1994Assignee: Recot, Inc.Inventors: John L. Center, Patrick J. Bierschenk

Patent number: 5341962Abstract: A feeder for discharging a load of material includes a hopper, a swing arm pivoting between raised and lowered positions in the hopper, and a ram mounted on the free end of the swing arm. The ram is moved by the swing arm back and forth on a curved floor in a trapezoidally shaped trough underneath the hopper to push material in the trough out of the hopper through a discharge outlet. A shutoff valve at the discharge outlet prevents backflow of discharged material into the trough.Type: GrantFiled: February 17, 1993Date of Patent: August 30, 1994Assignee: Cadence Environmental Energy, Inc.Inventors: Peter F. Way, William L. Petitjean

Patent number: 5289954Abstract: A device for metered removal of flowable solid material comprises at least one delivery opening for the flowable solid material and an essentially horizontal intermediate storage floor for receiving the flowable solid material, arranged below said delivery opening. A collecting space for the flowable solid material is defined between the intermediate storage floor and the delivery opening. A lateral opening is positioned in the intermediate storage floor adjacent to the delivery opening. At least one removal rake with at least one blade is inserted into the collecting space and movable relative to the intermediate storage floor transverse to a delivery direction of the delivery opening for pushing the flowable solid material collected under the delivery opening into the lateral opening. A pivoting parallelogram-shaped rod arrangement with upper pivoting axes that are arranged in a common horizontal plane is provided for pivotably supporting the removal rake.Type: GrantFiled: June 25, 1992Date of Patent: March 1, 1994Assignee: STEAG AktiengesellschaftInventors: Hermann Bruggendick, Karl Klinginger

Patent number: 5178304Abstract: In the doser-dispenser, the doser-piston 28 is carried by a first control tube 2 and the valve 32a forming with the central passage 32b of said piston 28 an intake valve 32 is situated on the side of the supply chamber 25 and is carried by a second control tube 35 guided in the first tube 2 and extending beyond the lower end of the latter. Each tube 2, 35 is surrounded by and integral with a bellows 6, 38 of which the inside is connected permanently to the outside atmosphere, the top end of the bellows being fixed either to housing 3 or to the lower end of the first tube 2. The second tube 35 with its intake flap 32a is controlled outside of the housing 3 by means of the piston 36 of a jack.Type: GrantFiled: January 4, 1991Date of Patent: January 12, 1993Assignee: Erca HoldingInventor: Roland Torterotot

Patent number: 5114040Abstract: A hopper dispenses cement or mortar into the space between side by side paving bricks. The hopper is a self supporting container. The container has opposing container sides converging downwardly to an elongated opening. This elongated opening extends for most of the length of the container. The opening has just below it a spaced pair of thin parallel guides for guiding the cement or mortar into the space between the paving bricks.Type: GrantFiled: January 7, 1991Date of Patent: May 19, 1992Inventors: Michael Brenish, Frank Herzig

Patent number: 5020698Abstract: An ice-cream ejector for ejecting ice-cream filled with solid ingredients into an edible cone from a cup having a lower outlet. The cup is supported on a sliding shelf. A piston is pressed downwardly into the cup by a hand lever to press the ice cream out. The piston is quickly removable from the ejector for cleaning. A flexible resilient header extends across the underside of the piston and is removable for cleaning. A disposable piston cover of wax paper clings to the piston header as the piston retracts. The piston has an inclined wall portion guiding the piston into alignment with the cup during piston entry. Visibility of the outlet during cone-filling is increased by a notch in the shelf and by having the cup outlet below the shelf.Type: GrantFiled: May 23, 1988Date of Patent: June 4, 1991Inventor: Jimmy L. Crossley

Patent number: 4972977Abstract: The present invention comprises a spray bottle in which the pressure resulting from the gripping force applied by the user is amplified and this increased pressure used in generating a spray such as an aerosol or fluid stream. In its preferred embodiment, the invention includes a high pressure chamber and a corresponding piston which is operative for driving fluid out of this chamber at high pressure through a spray nozzle and a low pressure chamber and a corresponding piston which is acted upon the hydraulic pressure within the bottle resulting from the gripping force. The low pressure chamber and piston are of larger size than the high pressure chamber and piston. The pistons are rigidly connected so that the force created by the pressure acting on the piston in the low pressure chamber is transmitted to the piston in the high pressure chamber where it is applied over a more limited area thereby generating greater hydraulic pressure for use in forming the spray.Type: GrantFiled: January 23, 1989Date of Patent: November 27, 1990Assignee: Battelle Memorial InstituteInventors: Owen R. Moss, Norman R. Gordon, Henry S. DeFord

Patent number: 4921133Abstract: A pump/dispenser, ratioing/mixer dispenser apparatus and a method and apparatus for precision vacuum degassed dispensing of work liquids are presented. The pump/dispenser is a positive displacement high precision piston/cylinder constant flush type with piston smaller than chamber. The piston is advanced along its stroke in tiny repeatable adjustably programmable steps, the infinitely adjustable precision ratioing programmable mixing being provided when two such pumps are used. The vacuum degassed work liquids dispensing system features the creation and maintenance of a positive absolute pressure on the work liquid(s) when exiting the degassing chamber(s) to the dispensing outlet(s) whether moved along the flow path through the precision dispensing pump(s) or other types of pump(s). Available softwear and adjustable programmable precision hardwear of the system may be provided by a widely available personal computer. Further degassing is provided by dispensing in a vacuum.Type: GrantFiled: August 24, 1989Date of Patent: May 1, 1990Assignee: Minnesota Mining and Manufacturing CompanyInventor: John O. Roeser
