Abstract: A hammer tool that has a handle member with grip and head ends. The head end includes a head assembly mounted thereon at an angle to give a user sufficient clearance for his/her hand grip when using the claw assembly built-in in the face. A blade assembly is removably mounted on the head assembly opposite the face and claw assembly. A magnetic member is inserted in the face portion to facilitate the manipulation of ferromagnetic nails. A holder with a frame and a loop is provided to support the hammer. The frame includes a hook member to which a headed engagement pin is removably mounted. When the hammer is mounted to the holder, the handle is kept at a convenient distance from a user's hands.

Abstract: An electronic ballast for gas lamp loads, such as ionized lamps, that includes a boost power factor correction used to correct the power factor and minimize the total harmonic distortion. The boost includes an inductor that periodically stores and discharges its resulting voltage in a charging capacitor through an optional bypass diode connected in parallel with an electronic switch using the oscillator that is applied to the load. The addition of the bypass diode decreases the total harmonic distortion. The inductor is selected, in combination with the rest of the circuit, so that it never reaches saturation. The inductor periodically charges the charging capacitor above (twice) the peak voltage that is supplied by a rectified continuous source of direct voltage. The high intensity discharge load is connected to a suitable resonant circuit.

Abstract: An apparatus and method for lifting tanks including supporting roof columns including the temporary installation of column support assemblies to those columns to permit cutting them at a sufficient distance from the bottom to allow a reinforced U-shaped support structures to be placed under the columns. A lifting device is placed below the U-shape support structure and in cooperation with wooden logs in criss-crossed arrangement, the structure is blocked up and down. The U-shaped support structures are interconnected to each other with rails that are soldered to the bottom of the tank thereby lifting the bottom simultaneously with the lifting of the columns and roof. The present apparatus and method is to be used in conjunction with lifting apparatus and methods associated with the outer peripheral wall of the tank.
