  • Publication number: 20020028309
    Abstract: A tubular, multilayer film comprises a central barrier layer and a pair of adhesive layers on opposite sides of the central barrier layer. The adhesive layers completely cover the central barrier layer. Opposing edges of the central barrier layer overlap longitudinally along the tubular, multilayer film. The total thickness of the central barrier layers in the overlapping portion is substantially the same as the thickness of the central barrier layer in the non-overlapping portion. The tubular, multilayer film also includes inner and outer surface layers. The inner surface layer extends completely around the interior of the tubular, multilayer film, and the outer surface layer extends completely around the exterior of the tubular, multilayer film.

  • Patent number: 6017145
    Abstract: An extruder screw for use in a barrel of an extruder for forwarding thermoplastic polymer from a first end to a second end of the extruder. The extruder comprises a transition section and at least one flight extending substantially along the length of the screw. A dam is positioned at the point where the rapid melting of the solids starts to slow down and the rate of solid bed width decrease approaches zero. The dam provides the screw with a high output of extrudate and close control of the residence time of polymer particles as they are transported through the screw, resulting in an extrudate which is uniformly melted and which is substantially free of degradation products and/or entrapped air.

  • Patent number: 4787033
    Abstract: Devices for interconnection into a digital computer system contain arbitration mechanisms for assigning control of a common communications path among the devices. Several modes of device arbitration are provided for, and the modes may be mixed among devices, and changed during operation of the system, in the system without interfering with communications. The arbitration mechanism requires only a single additional line in the communications pathway, and thus a single additional pin on the integrated circuit on which it is implemented, for the arbitration function. It thus facilitates implementation of the arbitration mechanism along with all other interconnect logic on a single integrated circuit.

  • Patent number: 4661905
    Abstract: Control of a communications path interconnecting separate devices in a digital computer system is provided by only two signals generated and received locally within each device on the path and asserted on a systems-wide basis on two separate lines of the path. The generation and utilization of the control signals is independent of the physical location of the devices on the path, and position-dependent delays in transmission of the signals from one device to another are avoided.

  • Patent number: 3999163
    Abstract: A secondary storage facility including magnetic tape, disk or drum units or other sequential access storage units. Each storage unit or drive connects to a controller by means of a device bus with asynchronous and synchronous paths. Status and controller information is coupled between the controller and a selected drive unit asynchronously over the asynchronous bus. Actual data transfers occur between the controller and a drive over the synchronous bus and between other units in the system and the controller using direct memory access or equivalent data transfers.
