  • Patent number: 6708504
    Abstract: The present invention relates to a system and a method for cooling extruded and molded materials. The present invention is especially useful to thoroughly cool an extrudate by releasing a cooling fluid in a hollow portion of the extrudate. Hollows may be created in order to reduce material, weight, and/or processing time. A fluid below about 80 degrees Fahrenheit is released into the hollow so as to cool the material and to assist in solidification. Increases in production line throughput may result by rapidly cooling the molded material. Other uses for the present invention include injection molding, compression molding, gas assist molding, and co-extrusion.

  • Patent number: 6705523
    Abstract: A system and method is disclosed for delivering supplies from a loading dock to a production line using a supply delivery computer system that interfaces with a conveyor computer system to control transportation of supplies from a conveyor system to pickup stations and a vehicle facility manager computer system to control automated guided vehicles that transport supplies from pickup stations on the conveyor system to delivery stations on a production line. Supplies are labeled with barcodes indicating production line delivery location (i.e., an identifier for a delivery station), load sequence number, load quantity, and lot number to facilitate tracking and routing from the time they are unloaded at the manufacturing plant loading dock on to the conveyor system until they delivered to delivery stations on the production line.

  • Patent number: 6651759
    Abstract: A hybrid electric propulsion system for powering a vehicle using a natural fuel engine and an electric motor. The hybrid electric vehicle is comprised of a drive train; an electric motor for driving the drive train; an auxiliary power unit (APU); an electric energy storage system electrically coupled to the electric motor; and wherein the auxiliary power unit and the electric energy storage system provide energy for powering the vehicle. An electric bus is directly connected to both the auxiliary power unit and the electric energy source and the voltage across the electric bus is substantially the same as the voltage across the electric energy source so that a change in voltage of the electric bus results in the same change to the voltage across the electric energy source. A power management controller is programmed to control output power of the power unit to maintain the energy storage system between a predetermined high voltage set-point and a predetermined low voltage set-point.

  • Patent number: 6637213
    Abstract: The present invention relates to a system and a method for cooling extruded and molded materials. The present invention is especially useful to thoroughly cool an extrudate by directing a cooling fluid toward a surface of the extrudate (e.g., an interior surface that defines a hollow portion of an extrudate). Hollows may be created in order to reduce material, weight, and/or processing time. A cooling fluid is diverted toward the surface of the extrudate so as to cool the material and assist in solidification. A baffle may serve to divert the cooling fluid in the desired direction. Increases in production line throughput may result by rapidly cooling the molded material. In addition, the more efficient cooling may be achieved with a lesser amount of the cooling fluid, and the velocity and temperature of the cooling fluid may be reduced. Other uses for the present invention include injection molding, compression molding, gas assist molding, and co-extrusion.

  • Patent number: 6633630
    Abstract: A system is disclosed for integrating electronic mail, voice mail, and fax mail in a universal mailbox. Message receivers may access their messages with a telephone or a computer regardless of the communication medium used by the message sender. Using a telephone, message receivers may playback voice mail, redirect fax mail, and “listen” to e-mail through a text-to-speech conversion process. Using a computer and modem, message receivers may playback voice mail, view fax mail, and read e-mail by accessing the universal mailbox via connection software. Message senders and receivers may choose from a variety of filter and forward options that allow them to manage their communications via the universal mailbox. Forwarding and conversion of messages is performed automatically. The options are used to define a set of rules to be applied to inbound and outbound messages so that messages are sent and received in accordance with the preferences of the senders and receivers.

  • Patent number: 6632364
    Abstract: An in situ method and system for reductive dechlorination, the precipitation of chromium, the precipitation of heavy metals, and microbial denitrification. The invention comprises the formation of in situ anaerobic reactive zones to precipitate and filter out dissolved heavy metals as metallic sulfides, to degrade nitrate to nitrogen gas, to reduce chlorinated hydrocarbons to ethene, and to precipitate and filter out chromium. The invention is comprised of an injection well or wells that extend into a contaminated groundwater. A conduit located within the injection well conveys a reagent to the contaminated groundwater. The reagent may be a carbohydrate rich solution. Microbes digest the carbohydrates to produce sulfate reducing and methanogenic conditions within the reactive zone that include a dissolved oxygen level less than about 0.5 mg/l, a redox potential less than about −250 mv, and a dissolved organic carbon to contaminant ratio of greater than about 50:1.

  • Patent number: 6621100
    Abstract: This invention relates to organic based spintronic devices, and electronic devices comprising them, including spin valves, spin tunnel junctions, spin transistors and spin light-emitting devices. New polymer-, organic- and molecular-based electronic devices in which the electron spin degree of freedom controls the electric current to enhance device performance. Polymer-, organic-, and molecular-based spintronic devices have enhanced functionality, ease of manufacture, are less costly than inorganic ones. The long spin coherence times due to the weak spin-orbit interaction of carbon and other low atomic number atoms that comprise organic materials make them ideal for exploiting the concepts of spin quantum devices. The hopping mechanism of charge transport that dominates in semiconducting polymers (vs. band transport in crystalline inorganic semiconductors) enhances spin-magneto sensitivity and reduces the expected power loss.
