  • Publication number: 20110208661
    Abstract: A system and method for calculating a space required for a tenant in a building includes determining the areas of rooms required by the tenant. A circulation factor for each of the rooms based on the area of each room is calculated. The total of the room areas and the circulation factors are added to determine a pure space required by the tenant. The losses in actual usable space are determined for a building and an inefficiency factor is calculated based on these losses. The pure space is multiplied by the inefficiency factor to obtain a building efficiency loss. The building efficiency loss is added to the pure space to obtain the space required for the tenant in the building. The system may be configured on a network computer system or a standalone computer.

  • Publication number: 20110198964
    Abstract: A procedure for casting a shorted structure around a plurality of induction motor rotors is described. The method comprises forming a wax representation of the shorted structure around a lamination stack; mounting a plurality of such lamination stacks in a mounting fixture and attaching a suitable gating and runner system; forming an investment by coating the structure with refractory followed by melting out the wax; casting molten metal into the investment while it is rotating and aligning the mold to allow the centrifugal force generated to promote mold filling; and, continuing to rotate the investment until solidification is substantially complete.

  • Patent number: 7974908
    Abstract: A system and method for promoting competitive bidding in an online auction that has a bidder, a favored bidder, and a sponsor, including receiving bids from the bidder and the favored bidder, deriving a relative spread, determining a market position for the bidder and the favored bidder, and displaying feedback information to at least one of the favored bidder or the bidder. The relative spread represents a minimum premium amount required before the sponsor awards a contract to a non-favored bidder. The market position reflects a comparison of the bid of the favored bidder to the bid of the bidder using the relative spread and the feedback information shows the market position.

  • Publication number: 20100288460
    Abstract: A method of forming a hollow sand core involves placing a preform into a cavity defined in a mold, where the preform has a predetermined configuration. A granular material is then introduced into the mold cavity and around the preform. The introduced granular material is established around the preform to form the hollow sand core. The preform is deformed in a manner sufficient to enable removal of the preform from inside the hollow sand core, and then is removed from the sand core. The removal of the preform exposes a hollow portion of the sand core.

  • Publication number: 20080249795
    Abstract: A system and method for calculating the amount of space that a user will be required to lease in various office buildings and providing a comparison so that the user can make educated decisions and pre-qualifications as to whether the building will be a viable leasing option for the user. In so doing, the system and method provide the user with relative values and target rental rates of the office buildings by considering the buildings' efficiency and corresponding amount of space the tenant will be required to lease. The calculated relative values and target rental rates may be used by tenants to evaluate building choices for leasing. The system may be configured on a network computer system or a standalone computer.
