  • Publication number: 20110033569
    Abstract: Embodiments of the present invention teach a post-mold treatment device and post-mold preform receptacle for use therewith for a post-mold treatment of a preform having a bell-shape. More particularly, an upper portion of a receptacle cavity associated with the post-mold preform receptacle is configured to have the same shape as the transition portion of the preform, and the upper portion is further configured to have a transition-fit size with respect to the transition portion of the preform at the instant that the preform is received from the molding cavity of the injection mold.

  • Publication number: 20110024950
    Abstract: The present disclosure relates to techniques for replicating large-scale nano-pattern structures using a block copolymer structure as a mask in a replication process. Example methods may include performing self-assembling block copolymer reactions to create large self-assembling nano-structures. The nano-structures may then be replicated by using the large self-assembling nano-structure as a mask in nano-imprint lithography.

  • Patent number: 7871552
    Abstract: The invention relates to an arrangement and a method for providing a roof tile with at least one water stop. With the arrangement it becomes possible to press a water stop, comprised of a material differing from that of the roof tile, into a roof tile blank. After the water stop has been pressed in, it is partially disposed with its edge in the material of the roof tile blank in the proximity of the watercourse, of the central brim and of the lateral beading.

  • Patent number: 7845923
    Abstract: A spinning, drawing and texturing machine for the production of curled threads includes a spinning unit and multiple machine modules associated with the spinning unit. Each of the machine modules has multiple processing assemblies for drawing and curling one of the threads, and a spooling unit for winding the thread. The machine modules positioned next to one another form a longitudinal side of the machine. The processing assemblies and the spooling unit are arranged among each other at one of the machine modules such that a narrow machine partition (T) in a range of <800 mm occurs on the longitudinal side of the machine. The spinning unit has one or more spinnerets and one spinning duct within the machine partition (T) per machine module. The spinnerets are held in rows parallel to the longitudinal side of the machine.

  • Patent number: 7828538
    Abstract: A method of increasing the intrinsic viscosity of polyester by means of solid state polymerization, wherein a polyester plastics melt is granulated and after granulation is conveyed into a thermal treatment container (13) for thermal treatment therein, the granules being produced slightly below their melting temperature and being fed into the thermal treatment container (13) immediately after granulation so as to utilize the residual heat in the granules, as well as an arrangement for increasing the intrinsic viscosity of polyester by means of solid state polymerization with a granulating and a thermal treatment unit, with an unheated, thermally insulated container (13) or a container (13) having wall heating means (15) being provided as the thermal treatment unit, which is directly connected to the granulating unit via a conveying device (11, 36, 37).

  • Publication number: 20100239704
    Abstract: A Styrofoam densification machine for melting used Expanded Polystyrene (Styrofoam) products. It includes a hopper for holding the disposed Styrofoam and a hopper discharge area for melting the used Styrofoam. The Hopper discharge area contains a heated tray compartment which holds a receiving tray for collection of melted Styrofoam. The compartment shall have two or less access area doors for the retrieval of the collection tray. The discharge and compartment tray areas have silicone heating pads on the outside of the panels for heat. The hopper is surrounded by a paneled cabinet which includes up to two inches of installation. The machine is loaded by way of mechanical hopper lid(s) which includes up to two lid panels, high temperature seals, hinges and handles for ease of opening. The machine sits on up to four (4) casters along with anchoring plates. The machine operates on 120 volts, 208 volts and 240 volts.

  • Patent number: 7785517
    Abstract: The present disclosure provides novel methods of producing a composition, such as, but not limited to, a polyimide composition. The methods in their most general form comprise providing a workpiece, suspending the workpiece and subjecting the suspended workpiece to processing such that the workpiece undergoes a transformation from a first state to a second state. By maintaining the workpiece in a suspended state during processing, processing-related defects are reduced or eliminated. Using such methods, the present disclosure provides compositions that are have no or reduced processing-related defects. In addition, the compositions are more consistent in chemical and physical properties and are cheaper and more economical to produce (since less product is rejected as unsuitable).

  • Patent number: 7753669
    Abstract: A system for flexing a web is disclosed. The web passes over two co-rotating members, such as rollers or belts, which are separated by a small adjustable gap. The web travels around the first rotating member, is peeled off in the vicinity of the gap, bent back on itself in a small radius and reattached on the second co-rotating member. The location of the small radius is fixed with a closed loop control system sensing the radius location and controlling the relative velocity of the two members. Strain in the web is adjusted with the size of the small radius, which is controlled by the adjustable gap and radius location.
