Patent number: 7695183Abstract: The apparatus is provided for impregnating a melt of polymer with a fluid working medium, such as, an expanding agent or an additive. Impregnation is carried out for the purpose of manufacturing foamed shaped parts using an injection molding machine. The impregnating body includes at least one melt channel formed in a gas permeable segment and a channel system for fluid infeed. The gas permeable material, e.g. sintered metal, separates the fluid from the stream of melt in the melt channel(s). Each melt channel has open pores at its inner surface which enable the impregnation. The melt channels can contain static mixers in the stream of melt to promote the distribution of the diffused fluid in the flow of melt.Type: GrantFiled: April 20, 2006Date of Patent: April 13, 2010Assignee: Sulzer Chemtech AGInventor: Sasan Habibi-Naini

Patent number: 7530463Abstract: A backwashable filtering device for thermoplastic plastics material is disclosed. The device can filter thermoplastic plastics material through one or more nests of screens in the filtering position, while submitting some nests of screens to the backwashing process that cleans them. The filtering position and the backwashing position are selectable by displacing one or more carrying bodies with respect to a housing and/or by displacing one or more control bodies with respect to the carrying bodies. The backwashing can be performed over an entire nest of screens or over a portion of a nest of screens. The nests of screens can be straight or curved.Type: GrantFiled: December 9, 2004Date of Patent: May 12, 2009Assignee: Erema Engineering Recycling Maschinen und Anlagen Gesellschaft m.b.H.Inventors: Helmut Bacher, Helmuth Schulz, Georg Wendelin

Patent number: 7448318Abstract: A machining waste metal recycling machine has an in-feed hopper. The hopper uses paired augers to move the waste metal through the hopper to a cutting and transporting auger. The hopper augers are powered independently from each other, and may be individually reversed or reversed as a group to clear jams. In the event a jam is not cleared through one or more reversal cycles, the remaining augers may be operated to clear the hopper, thereby avoiding the need for manual unloading. Within the hopper are one or more shear bars that are provided to sever bunches or bundles of machining waste and thereby clear tangles which might otherwise jam the augers. The cutting and transporting augers ultimately feed a reciprocating compactor having a movable gate with one or more grooves for controlled drainage of machining oil and other liquid, as the machining waste metal is compressed into pellets.Type: GrantFiled: August 20, 2007Date of Patent: November 11, 2008Inventor: Daniel J.

Publication number: 20080099953Abstract: An extrusion head is disposed over a substrate, and material is extruded through an oblique (e.g., semi-circular or tapered) outlet orifice of the extrusion head to form an associated extruded structure having an equilibrium shape that resists settling after being deposited on the substrate. The extrusion head includes fluidic channels having a flat surface formed by a flat first (e.g., metal) sheet, and an oblique (e.g., substantially semi-cylindrical) surface formed by elongated oblique trenches that are etched or otherwise formed in a second sheet. The fluidic channel communicates with the outlet orifice, which has a flat edge formed by the first sheet, and an oblique edge formed by an end of the oblique trench. The material is extruded through the outlet orifice such that its flat lower surface contacts the substrate, and its oblique upper surface faces away from the substrate. Two materials are co-extruded to form high aspect-ratio gridlines.Type: ApplicationFiled: November 1, 2006Publication date: May 1, 2008Applicant: Palo Alto Research Center IncorporatedInventors: David K.
