Abstract: A tubing head spool for use with a BOP protector in fracturing or stimulation treatments is described. The tubing head spool includes a reinforced area of its sidewall that is adjacent a bottom flange of the spool and surrounds a supports an annular seal which provides a sealing engagement between the end of the BOP protector and a secondary seal in a bottom of the spool.      The reinforced area contains radial pressure transferred through the annular seal during well stimulation treatments. The reinforced area has a pressure rating greater than the pressure rating of the remainder of the tubing head spool so that the modified tubing head spool is adapted for use with the BOP protector for high pressure well stimulation treatments. The advantage is an economic tubing head spool that enables safe high pressure well treatments at pressures up to the pressure rating of the reinforced area of the tubing head spool.

Abstract: A communication network, which includes a plurality of switches, routes a call from a receiving switch to a destination switch either directly or through an alternate switch. Either the receiving switch or the destination switch, or both, analyze the contents of a store to determine whether the calling party or the called party is marked for alternate routing. The call may be routed to the alternate switch either from the receiving switch or the destination switch if the call is marked for alternate routing.      The inventive method includes transmitting a two part call information signal to the destination switch from the receiving switch if the call is not marked for alternate routing. If the call is marked for alternate routing, a three part call information signal is transmitted to the alternate switch. The alternate switch then recreates a two part call information signal and transmits that signal to the destination switch as it routes the call thereto.

Abstract: A skate (20) hingedly attached to an elongate ice blade (24) by a frame (22).  The skate having an upper shoe portion (26) adapted to receive a foot, and a sole defining a heel end, a metatarsal portion having a metatarsal head area, and a toe end. The skate further includes a midskate hinge member (12) defined the metatarsal head portion to permit the upper shoe portion to flex in the metatarsal portion, allowing the heel end to lift away from the ice blade, while the toe end remains substantially parallel with the longitudinal direction of the ice blade.

A mid-boot support mount (70) extends upwardly from the frame and is adapted to support the plate at a predetermined location behind the metatarsal head area of the sole to maintain the plate in a stable position as the skater pushes down on the plate and applies thrust to the ice blade. The skate also includes a forward hinge member (10) hingedly attaching the first end (54) of the plate to the ice blade, such that as the upper shoe portion hinges at the forward hinge member and about a lateral axis defined normal to the longitudinal direction of the ice blade, the mid-boot hinge member unflexes and the skater is able to push-off from the forward hinge member without the tip end of the ice blade digging into the surface it is traversing.

Abstract: A method is provided for inventory management which includes an initial step of receiving a customer request for an inventory item and then generating a table or menu of one or more inventory items that most closely correspond to the customer request using a price forecasting system (14). Based on negotiations concerning price, timing and other typical concerns, an item is selected from the table and a price quotation associated with the selected inventory item is generated usi ng the price forecasting system, which price quotation has been predetermined by a yield management system (22) using a pricing strategy. Th e customer information associated with the customer request is input into a traffic billing system (20). Information needed for price recalculation associated with the customer request is input into the yield management system. The yield management system recalculates pricin g data with in a manner consistent with a pricing strategy implemented by the yield management system, so that the price changes caused by a reduction in available inventory due to the customer request are taken into account, and the pricing data accessed by the price forecasting system when a price quotation is generated is updated prior to repeating the process for a subsequent customer request.

Title: Enhanced dual counter rotating ring network control system
Inventor: PENG WANG-HSIN
IPC: H04L69/40
Filed: 2000-06-12
Granted: 2009-11-24
Abstract: A control system enables transport of payload data across a dual counter rotating ring (DCRR) network having two or more nodes, each node providing access to the DCRR network by a respective local area network (LAN) subtending the node. The control system comprises a topology learning entity operative within each node for monitoring individual links of the DCRR, discovering the active topology of the DCRR, communicating topology changes to other nodes in the DCRR, and informing frame forwarding and learning processes of the topology to enable failover to redundant resource upon detection of a network component failure. A frame forwarding process selects a shortest path route between a source and a destination node in the DCRR, and forwards frames to the destination node via the selected shortest path route. An address learning process inspects a source medium access control (MAC) address in each received frame to learn a shortest path route for each MAC address.

The liner ply provides a moisture and gas barrier inside the container around the product.  The container may include a label ply. The label ply defines at least one aperture therethrough. The cuffing of the at least one aperture in the label ply is registered. The body ply defines at least one aperture therethrough corresponding to the at least one aperture in the label ply. The body ply is wrapped around the previously wrapped liner ply on the mandrel and then the label ply is wrapped around the previously wrapped body ply and liner ply so that the apertures in the label ply are aligned with apertures in the body ply to create a tubular shape having a viewing window through both body plies.

Abstract: A preassembled unit for a sewage nitrification field has minimum outward dimensions of loose, lightweight plastic aggregate material enveloped and bound by a plastic sleeve around a horizontal conduit. In one embodiment, the unit takes a bag form with an aggregate-filled netting sleeve concentrically surrounding and fastened to the ends of corrugated plastic vent pipe. In another form, the sleeve is a plastic extrusion of rectangular cross-section and the conduit can be formed integrally with the sleeve. Cross-webbing is added for strength. In ground installation, conduitless units make up the insufficiency of aggregate dimension. Mating male and female end caps are used to interconnect the conduit of adjacent units end-to-end. Apparatus for manufacturing the concentric netting sleeve/vent pipe version has a hopper that discharges aggregate into the top of a mandrel and an annular disc or helical auger blade that pushes the aggregate forward into the sleeve.
