Patent number: 4557402Abstract: A hopper feed apparatus for the powder hopper of a powder reinforcing machine, to keep the hopper and its supply conduit free of clogged powder, the apparatus comprising of an arrangement of springs attached to the top of the hopper on the inside thereof, which springs extend downwardly to a common point near the discharge orifice, to where they are attached to a line which extends through the conduit. The lower end of the conduit is secured to a movable dispensing apparatus, which when it moves, pulls on the line and biases the springs, all of which agitate any powder within the hopper and the conduit, preventing it from caking and otherwise clogging the system.Type: GrantFiled: December 15, 1983Date of Patent: December 10, 1985Assignee: USM CorporationInventor: Albert I. Morse

Patent number: 4505591Abstract: Solids mixing well structure and methods are disclosed for mixing a solid having a first specific gravity with a fluid having a second specific gravity to produce a slurry having an intermediate specific gravity and a resultant pressure greater than atmospheric pressure. The solids can then be transported in the form of a slurry using the resultant pressure. At no time do the solids come in contact with a pump member. The apparatus and methods are particularly suited for transporting coal and solid waste material. No moving parts are required other than a pump to supply fluid pressure. A first cylindrical member receives at its inlet fluid at a pressure greater than atmospheric pressure and delivers the fluid at a first pre-determined pressure to a mixing region. A second structure receives at its inlet solids at atmospheric pressure and delivers the solids at the first pre-determined pressure to the mixing region down stream of the fluid.Type: GrantFiled: December 20, 1982Date of Patent: March 19, 1985Assignee: Geosource Inc.Inventors: Roger W. Day, Charles N. Grichar

Patent number: 4498986Abstract: A vibratory container for flocculating waste water obtained upon vibratory abrasive finishing or the like, having an outlet and a feed connection which continues into a feed channel which extends into the inside of the container and is arranged in siphon-like manner with respect to the outlet pipe. For improved treatment of even chemically complex working liquids, the inside of the container is subdivided by partition walls into a plurality of chambers arranged one downstream of the other in the direction of flow. Connections are associated with the first two chambers arranged downstream of the feed channel within the initial region of the flow. The connections serve to introduce flocculation preparation chemicals, while a final connection is provided for the addition of the flocculating agent.Type: GrantFiled: March 1, 1983Date of Patent: February 12, 1985Assignee: Carl Kurt Walther GmbH & Co. KGInventors: Karl Temme, Klaus Beckschafer, Helmut Pruller

Patent number: 4475820Abstract: Flexible shafting has an outer flexible shaft with a hollow central bore for receiving an electrically insulating flexible tube which, in turn, receives an inner flexible shaft therein. The outer and inner flexible shafts are capable of rotating independently of each other while simultaneously transmitting an electric current.Type: GrantFiled: October 22, 1982Date of Patent: October 9, 1984Assignee: Pennwalt CorporationInventor: Gerard M. Mulligan

Patent number: 4448360Abstract: A continuous output food processor has a bowl with a chute adapted to direct food processed by the food processor laterally out from the bowl. An inclined vibrating deck is mounted in the bowl below a food processing tool. This deck extends on a downward incline laterally out from the bowl through a chute. Food processed by the rotary tool becomes deposited on this vibrating deck and is guided and moved by the vibrating deck out from the bowl for discharge into a waiting container positioned under the outer end of the chute. The vibrating deck as well as the rotating food processing tool are driven by the electric motor drive of the food processor. The vibrating deck is driven by an eccentric coupled to such drive through a connecting rod coupled at its other end to a wrist pin mounted on the deck. The deck is provided with a plurality of pivot link mounts as spaced locations to facilitate the vibrating motion and stabilize the inclined orientation of this deck.Type: GrantFiled: September 30, 1981Date of Patent: May 15, 1984Assignee: Cuisinarts Research & Development, Inc.Inventor: James E. Williams

Patent number: 4448540Abstract: An apparatus is disclosed which is useful for mixing ammonia, in a vapor-liquid phase, with an additive composition, in a liquid phase, to obtain a homogeneous vapor-liquid mixture of the anhydrous ammonia and the liquid additive compound. The apparatus described herein is particularly suitable for use in a field applicator, for applying the anhydrous ammonia to the soil, as a nitrogen fertilizer, in combination with an additive, such as a nitrogen stabilizer. In operation, the vapor-liquid ammonia stream is metered through a meter regulator and then passed downwardly into a mixing chamber. Below the meter regulator is a delivery tube through which the liquid additive is metered into the ammonia stream before entering the mixing chamber. Inside the mixing chamber the ammonia-additive stream is further mixed to obtain a homogeneous mixture, which is then passed downwardly into a distribution chamber. From this chamber the mixture is delivered to a use point, such as a row of soil knives in a field applicator.Type: GrantFiled: June 4, 1982Date of Patent: May 15, 1984Assignee: The Dow Chemical CompanyInventor: David M. McLeod
