  • Publication number: 20110126745
    Abstract: A refractory anchoring system that mitigates the effects of the thermo-mechanical stresses that arise from the furnace temperature gradient and varying thermal expansions of the refractory and casing. This anchoring system provides independent movement which may be important for maintaining the refractory lining stability and its ability to contain the furnace processes. The invention relates more specifically to the metallic member that is configured in a specific spring-like manner. This invention also relates to the specific design of the non-metallic member (refractory anchor) to work in conjunction with the metallic member.

  • Publication number: 20100257095
    Abstract: A banking system includes terminals and a computer operable to act as a server on a network and to communicate with each terminal. The computer includes a memory configured to store a set of instructions and a processor configured to execute the instructions. The instructions cause the processor to: receive a deposit request from a terminal, the request comprises an amount of funds to be deposited, and instructions indicating a percentage of the funds to be deposited into a cash-on-hand account; credit the account with an amount of funds equivalent to the percentage of the deposited funds instructed therefor; and transfer funds to a cash-on-hand reserve, wherein the amount of funds transferred to the reserve is equivalent to the amount of funds credited to the account. The funds transferred to the reserve are not eligible for conventional banking activities, and the reserve is only diminished by withdrawals from the account.

  • Patent number: 6905282
    Abstract: A vehicle mounted crash attenuator includes first and second bays mounted together at a rotational joint. One or more hydraulic cylinders are mounted between the bays to move the second bay between a deployed position, in which the first and second bays are aligned horizontally, and a retracted position, in which the second bay is rotated about the rotational joint by a rotation angle greater than 90° from the deployed position. In this way, the second bay is raised above the first bay, and the overall length of the crash attenuator is shortened, all without excessively increasing the overall height of the crash attenuator.

  • Patent number: 6789291
    Abstract: A telerobotic nozzle positioning system for a mobile debris vacuum vehicle or for fixed particulate vacuuming applications. The apparatus has a vacuum source coupled to an adjustable boom and nozzle assembly. The nozzle assembly is mounted to the boom with a compliant upper joint that will allow the nozzle assembly to withstand impacts with obstructions without shearing the nozzle assembly from the boom. A base with an extensible fly is pivotally coupled to the upper joint and can swing with respect to the joint upon actuation of a short stroke hydraulic cylinder. The distal end of the extendable fly has a nozzle bracket assembly with a nozzle bracket, flexible hose and nozzle tip. The nozzle bracket and nozzle tip can pivot with respect to the fly. A pair of long hydraulic cylinders allows the extension of the fly from the base as well as rotation of the nozzle bracket and tip.
