With Separate And Distinct Upstream Agitating Or Kneading Means Patents (Class 425/200)
  • Patent number: 11141880
    Abstract: A method and system for forming vertical wall construction units in one or more provided forms provides environmentally-manageable construction with reduced labor burden over existing non-traditional construction techniques. The method is a method of operation of the system, which includes a programmable controller, a reciprocating tamper head, a positioner that is guided to position the tamper head, and a filling mechanism for introducing loose material to a form in pre-determined layer volumes to provide loose material for individual layers of the prefabricated vertical construction unit. The programmable controller operates the filling mechanism to introduce the loose material for the current layer, then operates the three-axis positioner to guide the reciprocating tamper head over a horizontal cross-section of the form at a height determined for the current layer and along a program-determined path to compact the current layer.

  • Patent number: 9073239
    Abstract: A vacuum vibration press manufactures engineered stone slabs that are equal or superior in appearance and physical properties to slabs manufactured using a conventional Breton press, while weighing less, costing less to manufacture, providing shorter press cycle times, requiring less resin, and consuming less energy. In addition to providing a vibration device above the slab, the press also includes a second vibration device below the slab, which replaces the massive inertial base of a Breton press. The vibration devices can have different frequencies, amplitudes, and/or vibration axes. The press can be completely enclosed within a vacuum chamber, and vibrationally isolated from surrounding structures. In embodiments, volume reduction blocks reduce the volume to be evacuated. Embodiments use screw jacks and springs or air bags to provide controlled pressing force and precisely uniform slab thickness. Slabs can be inserted and removed on a conveyor belt, or in separate trays on rollers.

    Abstract: For forming a ready-to-bake, endless dough ring, a dough piece is first round kneaded in a round-kneading station and then fermented in a fermenting station. In a pressure station, flattening pressure is exerted on two sides of the dough piece for a flat round piece to produce. After a relaxation interval, an inside hole is punched into the relaxed dough piece in a punching station, with a dough ring being obtained. The individual stations of a corresponding dough treatment system are connected to each other by means of a conveyor. Then secondary fermenting of the shaped dough ring takes place, which is followed by baking of a ring article. The result is an efficient method of forming a ready-to-bake, endless dough ring.

When the assembly is transporting high-temperature extrudate, the biasing member's included Belleville washer component compensates for the thermal expansion and contraction of the extrusion screw.

  • Publication number: 20080230931
    Abstract: The object of the invention is a process for molding an optical element such as a lens (2). According to the invention, the element is obtained by a reaction injection molding process comprising the steps of mixing at least two polymerizing reactants and forcing the obtained reacting mixture by an injection duct (5) for filling under pressure a scaled mold cavity (4) having an entry side (43) provided with a casting opening (42) and an evacuation side (44) and providing a laminated flow of mixture in a spout (6) having a progressive enlarging transversal section between the outlet opening (52) of the injection duct (5) and the casting opening (42) of the mold cavity (4), for avoiding any turbulent area in said laminated flow, said evacuation side (44) being provided with means (45) for evacuating air contained in the mixture during mold filling. The invention also covers the molding installation adapted for using such a process.

  • Publication number: 20080048358
    Abstract: The invention relates to a method and a device for producing Lyocell fibres which are extruded from a cellulose solution of water, cellulose and tertiary amine oxide in a spinning head (25). The cellulose solution is obtained in a number of process steps directly from the cellulose (3, 4) or with the formation of a cellulose suspension. Since the degree of polymerisation decreases in the course of processing the cellulose through to its extrusion in the cellulose solution, with the processing of celluloses with a low degree of polymerisation there is the risk that the endless moulded bodies (2) extruded in the spinning head (25) exhibit defective quality.

  • Patent number: 7318717
    Abstract: A method and apparatus for combining raw fibrous and binding materials in a single mixing step (Step S3), followed by consolidation (Step S5) so as to greatly shorten the overall cycle time to a finished fiber-reinforced composite part. Chopped fibrous materials and binder materials are deposited sequentially onto a belt conveyor (Step S2) so that the materials are successively layered, one on top of each other in a predetermined ratio, and subsequently mixed (Step S3) to achieve uniform dispersion throughout. The mixed materials are then deposited into a rotating mold (Step S4) to further ensure uniform dispersion of fibrous and binder materials. Impregnation of the fibrous materials with the binder material occur in-situ as the uniformly mixed materials are heated and subsequently compacted in the mold (Step S5) to obtain the desired shape of the fiber-reinforced composite part.

  • Patent number: 7097442
    Abstract: An extruder capable of obtaining a treatment volume equal to that of the conventional art without enlarging a screw diameter is provided. The extruder includes screw shafts, a drive unit, and a barrel, in which three or more screw shafts having the same diameter and the same root diameter in a waveform shape are engaged with each other and arranged in parallel to each other horizontally or nearly horizontally, while a distance between axial centers is made equal. According to the above configuration, the same treatment volume as that of a conventional extruder can be handled by screw shafts of smaller diameter as compared with that of the conventional art. By using the screw shafts of the smaller diameter as compared with the conventional art, temperature irregularities of an extrusion material in screw grooves, leakage of the extrusion material from the screw shafts, an installation area of the extruder, and the like conventional trouble of various kinds can be eliminated.

    Abstract: An injection unit for an injection molding machine includes an injection device in the form of a plunger/screw, which is driven axially and rotationally in a housing, and a device intended for mixing and metering plastic melt and including an inlet for introduction of an additive. A spacer element is disposed between a backflow prevention assembly of the screw and the plunger, with the spacer element having a length, which corresponds at least to the stroke of the injection device. The spacer element has a first flow channel for establishing in each position a fluidic connection with a second flow channel which initially extends radially in an outward direction and then parallel to the movement and guide area of the plunger to an area between a nozzle and the plunger. The second flow channel extends through the mixing and metering device arranged adjacent to a movement and guide area of the plunger.
