摘要： A plastic melt machine includes a feed screw rotatably mounted in a barrel and driven in rotation about a longitudinal screw axis of the feed screw by a screw drive to plasticize material, and an apparatus for driving a device independently of the feed screw. The device can be any rotatable device associated with the feed screw wherein the device is rotatable about a drive axis and is in fluid communication with the barrel to receive the plasticized material. The drive axis is coaxial with the screw axis. A drive shaft couples the device to the device drive, or to the screw drive through a speed changer, for rotating the device independently of the rotation of the feed screw by the screw drive.

摘要： A mixer for plasticable resins has a fixedly positioned heated barrel with a power driven screw mounted axially in the barrel bore, a driven rotor is axially aligned with and extending in a downstream direction from the downstream end of power driven screw. A series of elongated rotor flow transfer cavities are in the outer surface of the rotor. The rotor flow transfer cavities extending inwardly and are arranged in a plurality of axially aligned rows and a plurality of annular rows concentric to the axis of the rotor. A floating sleeve is coaxially positioned over the power driven rotor and interposed between the rotor and the barrel so as to be capable of independent rotation relative to both the power driven rotor and the barrel. The floating sleeve has a plurality of parallel outwardly extending ring flanges extending radially outwardly and inwardly facing a plurality of annular and elongated in cross-section outer sleeve flow channels each having an upstream end and a downstream end provided between adjacent ring flanges. A series of outflow apertures extend through the floating sleeve and communicate on opposite ends with the upstream end of an elongated outer sleeve flow channel of the floating sleeve flow channel and the downstream end of one of the elongated rotor flow transfer cavities of the rotor.

摘要： Extruders are widely used to transform solid plastic materials into molten plastic materials. Because of the low thermal conductivity of plastic materials and the inefficient mixing of the plastic materials inside an extruder, the heat is not evenly distributed in the material being processed and some portion of the material emerges from the extruder with excessive heat. This invention discloses a new screw with a novel mixing section which promotes mixing of the hot, molten material with the cold, unmolten material inside the screw channel by its unique geometry, thereby improving the heat transfer from the hot, molten material to the cold, unmolten material and increasing the energy efficiency of the extruder.

摘要： A no solid bed extruder screw for processing a material to a molten state has a body with a helical thread formed thereon, the thread having pushing and trailing surfaces. The body has an outer surface and extends longitudinally between feed and discharge ends. A channel for receiving the material to be processed is defined between the outer surface of the body and an outer diameter of the thread bounded by the pushing surface and the trailing surface of the thread. A volume of the channel decreases in a plurality of revolutions of the thread in a direction from the feed end to the discharge end. A channel depth between the pushing surface and the trailing surface decreases for a first portion of the channel toward the feed end and increases for a second portion of the channel toward the discharge end.

摘要： A helmet for wearing by a sports player comprises: a bubble-shaped body having a hollow interior surrounded by a wall and an opening formed in the wall for inserting a head of the player, and a fastening device for releasably fastening the body to shoulder pads being worn by the player. At least a portion of the wall is formed of a transparent material. Alternate designs are also disclosed, including a helmet constructed of a plastic-coated wireframe, and a non-transparent plastic helmet with a face mask, where in all cases the helmet is rigidly but releasably attached to a chest pad or shoulder pad worn by the player, so that impact forces on the helmet are not transferred to the player's head.
