    摘要: A distribution transformer having a slot-and-tab core frame assembly. The core frame (17) encloses a transformer core (11) having at least one phase and provides compression on the core yokes and end members of the transformer to bind the assembly together. First and second clamps (10, 24) of the core frame contain receiving slots (34) for the tabbed (18, 28), longitudinal side supports (20), creating an interlock when connected. For larger transformers, the tabbed side supports may be alternatively comprised of a subassembly of end plates, cams, and tabbed locking plates, encompassing a sturdy locking mechanism.

    摘要: Foam fracturing fluids and methods for fracturing well formations using foam as the carrier for the propping agent are disclosed. The foams are stiff stable foams formed of a relative large amount of gas and a relative small amount of liquid. The foams are stable at surface pressures and remain stable when delivered into the well formation at the bottom of the well.

    摘要: A water closet bolt comprises an upper end and a lower end with a threaded body extending therebetween. The lower end includes an oblong foot and the upper end includes a male or female notch for visually indicating the orientation of the long axis of the oblong foot. The notch also serves as a gripping surface to aid the installer in the installation of the toilet. Furthermore, the bottom of the notch acts as a break-off point to aid the installer in removing an excess portion of the bolt after the completing the installation.

    摘要: A method of checking a large and/or replicated databases includes forming a position sensitive checksum for each entry of the database to be used in the check. The checksums are then exclusive Ored with one another to form a first database checksum. Periodically, the checksums are again created from each of the entries of the check and a second database checksum formed and compared to the first for a match that indicate checked entries of the database have not changed. In another embodiment, a modification to one of the check entries may be provided, accompanied by a master checksum indicative of what the first checksum should be after the entry is modified. The database entry is modified, and a position checksum value for the entry as modified is created. The checksum value for the modified entry, and for the entry before the modification, are exclusive OR with the first checksum value, and that result compared with the master checksum to ensure that the modification was properly made and that the database remains credible.

    摘要: An elongated movable water cooled mold of any desired cross section has an open bottom end which is lowered into a pot of molten metal a predetermined distance with the metal being pulled into the mold under vacuum operated by suitable controls for establishing the desired length of the casting or billet. Water is supplied to the mold while still in the pot to permit the casting to harden and the mold is then removed therefrom and moved to a position close to floor level where termination of the water supply allows the contained heat in the casting to reheat the mold and expand it sufficiently so that the casting can drop free of the mold upon release of the vacuum.
