  • Patent number: 11045999
    Abstract: A throat structure for a 3D printer according to an embodiment includes a cold zone for heat dissipation, a hot zone for heating, and a thermal insulation zone. The cold zone for heat dissipation has a titanium throat outer tube body and a teflon throat inner tube body, and the teflon throat inner tube body is socketed in the titanium throat outer tube body. The hot zone for heating has a heating block connection zone and a nozzle connection zone. The heating block connection zone is located on an external side of the hot zone for heating, and the nozzle connection zone is located at a lower part of the hot zone for heating. The thermal insulation zone is connected to the titanium throat outer tube body such that an area of the hot zone for heating is reduced and a printing material extrusion amount is controlled.

The apparatus of this invention results in homogeneous deformation of a material, such as molten polymer, polymer solution, multiphase polymer systems, asphalts or foods.

  • Patent number: 5888266
    Abstract: Apparatus which is disclosed comprises a metal mold, a metal plunger and an annular manifold, and includes means for moving the plunger and the manifold between an open position in which the manifold surrounds the plunger and a gob of softened glass can be introduced into the mold and a closed position in which the manifold surrounds the plunger and the latter forms, with the mold and the manifold, a cavity in which a glass part can be formed. The manifold and the plunger have facing walls which are above the mold cavity, have portions which are in close fitting sliding engagement, and, thereabove, portions which diverge away from one another and form an annular space.

  • Patent number: 5547358
    Abstract: Devices are disclosed for forming egg-yolk disks by wire-cutting egg-yolk material extruded from a main cylinder. The main cylinder ends to an extrusion-head. The extrusion head may be threaded on a cylinder to a desired degree, so that during the disk-cutting process, the cutting wire slides on the front surface of the extrusion head. The Devices may also have a mechanism for locking the extrusion head in position. Miscellaneous mechanisms for wetting the cutting wire are also disclosed.

  • Patent number: 5427515
    Abstract: An apparatus for producing a stress free sheet of dough having uniform height and width can be economically and conveniently used with a batch dough system. Individual dough batches are deposited into a retention hopper from which equal volumetric dough portions are sectioned by a pair of oppositely rotating co-acting cutters. Each cutter includes a number of blades which cooperate with corresponding blades on the opposing cutter to section the dough into portions. The dough portions are deposited onto an inclined conveyor positioned below the hopper so that a leading end of each dough portion overlaps a trailing end of the previous dough portion. A photo-electric detection device ascertains the trailing end of the previous dough portion and signals the cutters to section the next successive dough portion. The overlapping dough portions are then formed into a dough sheet having uniform height and width by a pressing roller and a combination of side guide wedges and side pressing rollers.

  • Patent number: 5348697
    Abstract: A method and apparatus for the production of reinforced plastic objects uses a body form around which a casing having a cover is placed. The cover includes two cover units which between them defines an opening having an adjustable size and position. The opening provides access into the body form so that reinforced plastic material may be applied therein. The size of the opening is minimized to reduce the amount of environmentally harmful substances escaping therefrom, such as styrene. The position and size of the opening relative to the body form is adjustable to provide a convenient access into the body form.

  • Patent number: 4884960
    Abstract: A honeycombed structure is extruded and wash coat applied to the interior channels of the structure before the honeycomb structure is separated from the die in which it is formed. This method produces the honeycombed structure using a die that includes a die body having an inlet and an outlet side, a plurality of parallel pins defined by the body that correspond to the shape of the channels in the honeycombed structure, and a discharge zone that communicates directly with the outlet side of the die and is defined by the open area between the pins. The extrudable material enters the discharge zone from a series of feed passages defined by the pins and a plurality of webs that interconnect the pins. Each pin has an interior duct with an opening at the end of each pin. A series of internal passages in the die body receive fluid from one or more ports on the periphery of the die and distribute the fluid to the ducts.

  • Patent number: 4861250
    Abstract: An in-mold sulfonation system for sulfonating the surface of plastic articles such as plastic containers during molding. Sulfur trioxide is introduced into a pre-mold chamber, converted to a relatively high pressure gaseous sulfur trioxide, and then injected into a mold such as a blow mold immediately before or immediately following full expansion of the formed plastic article in the mold cavity. Neutralization with a gaseous neutralizing agent follows. By controlling the timing and temperature of the in-mold sulfonation step it is possible to produce a plastic article having an effective barrier layer but containing a minimum of undesirable rinseable salts.

  • Patent number: 4770619
    Abstract: Rolling apparatus comprising two rollers (FIG. 1) or (FIG. 2) disposed horizontally adjacent to each other, one roller of which has a rough surface. Above the gap between these rollers is a stock holder with an open bottom end. Dough placed in the holder falls onto the rollers and is conveyed by the roller through the gap, so that a strip of dough leaves the gap. Disposed below the gap is a third roller which is parallel to the two top rollers. Rotatably mounted on the periphery of the roller are a number of rolls. The strip of dough goes from the gap through a gap between the bottom roller and the top roller (FIG. 1) or (FIG. 2), which is preferably a roller of the same type as the bottom roller, opposite the top roller with rough surface, so that the rolls make the strip of dough thinner, while retaining its structure.
