Abstract: A center beam connection assembly for temporary shoring includes a pair of end-caps adapted to fit over respective ends of a center shoring beam. Arms extending from each end-cap engage a web of a main shoring beam in a excavation site shoring system. The end-caps may be used alone, or in combination with reinforcing and spacer bars. Reinforcing bars include first and second hooks adapted to connect to a main shoring beam and a center shoring beam, respectively. When utilized, each spacer bar is connected to at least one tab on an end-cap and at least one tab on a reinforcing bar via connecting pins. In this manner, one or more center shoring beams can span an excavation hole to provide removable, reusable and temporary support for a shoring system.

Abstract: A shoring beam extension and reinforcement assembly allows a user to removably connect a plurality of shoring beams together so as to customize a support assembly to a particular excavation site. In use, main shoring beams extending around the periphery of an excavation site are connected at the corners by corner connections and are connected along the longitudinal sides of the excavation site by the extension of reinforcement assembly. Additionally, the first and second connectors support a center shoring beam laterally across the excavation site. The assembly is provided with additional support by tabs extending from each of the first and second connectors. Reinforcing beams include tabs having apertures adapted to align with apertures in the tabs of the first and second connectors such that connecting pins may be inserted there through to connect the reinforcing beams with the connectors. Eyelets located on the first and second connectors provide a means by which the assembly may be supported.

Abstract: Internet acquisition of goods and services from multiple service providers is facilitated in a uniform, automated manner. Online service account facilitation systems and methods are contemplated that allow for intuitive, uniformly-structured representations of service offerings; straightforward, yet flexible, definition of service product markets; advantageous status designations for market offerings; flexible start date restriction rules; context sensitive information request forms, dynamic price determination on interactive comparison forms; flexible restriction rules for selection combinations of plans, packages, and features; creation of customized data elements; a powerfully advantageous ordering process; a discontinuation process; an inter-dependent order resolution feature; a hierarchical customization scheme; and/or centralized two-way communication between customers and service providers.

Abstract: Apparatus is shown for substantially increasing the feed rate of pulverized material into a pressurized container. The apparatus includes a rotor that is mounted internal to the pressurized container. The pulverized material is fed into an annular chamber defined by the center of the rotor. A plurality of impellers are mounted within the annular chamber for imparting torque to the pulverized material.

Abstract: Apparatus is shown for feeding a slurry to a pressurized housing. An impeller that includes radial passages is mounted in the loose fitting housing. The impeller hub is connected to a drive means and a slurry supply means which extends through the housing. Pressured gas is fed into the housing for substantially enveloping the impeller in a bubble of gas.

Abstract: A device for pressurizing pulverized coal and circulating a carrier gas is disclosed. This device has utility in a coal gasification process and eliminates the need for a separate collection hopper and eliminates the separate compressor.

Abstract: Method and apparatus are shown for the continuous feeding of pulverized material to a high pressure container. A rotor is located within the high pressure container. The pulverized material is fed from a feed hopper through a stationary feed pipe to a vented spin-up chamber to a plurality of two-stage sprues mounted in the rotor. Control nozzles downstream from the sprues meter the flow of coal through the sprues.

Abstract: Method and apparatus are shown for control of continuous feeding of pulverized material to a high pressure container. A rotor is located within the high pressure container. The pulverized material is fed from a feed hopper through a stationary feed pipe to a vented spin-up zone chamber to a plurality of sprues mounted in the rotor. Control of the pressure within control nozzles downstream from the sprues adjusts the flow rate of coal through the sprues.

Abstract: Apparatus is shown for adjusting the feed rate of pulverized feed material into a pressurized container. The apparatus also has utility for compensating for variations in the permeability of the feed material. A rotor that includes sprues with provision for controlling the pressure distribution along the sprues is located within the pressurized container. The rotor hub is connected to a drive means and a material supply means which extend through the wall of the container. A line for controlling pressure along the sprues by gas injection is connected to a chamber between sections of the sprue for controlling gas pressure at that point. The gas pressure control line is connected to a pressurized gas source and a control system external to the rotor.
