  • Publication number: 20040108115
    Abstract: A method and apparatus for remediation of non-aqueous phase liquids (NAPL) in a well. The apparatus includes a continuous loop absorption device for extracting NAPL from the well, a casing covering the well, at least two pairs of brackets located inside the casing, and at least two squeegee rollers supported by the brackets, wherein each squeegee roller includes an axel supported by a pair of brackets, the axel being enclosed within the casing.

  • Publication number: 20040076285
    Abstract: An apparatus (310) for intercepting telephone calls on a telephone channel connected to a telephone includes a ring detector, that is in communication with the telephone channel. The ring detector is capable of detecting an incoming telephone call and generates a ring signal upon detection of an incoming telephone call. A user input receives an input from a user indicating that the user desires not to be called. A counter (320), that is responsive to the user input, is programmed to count a selected amount of time from assertion of the user input. A delay circuit (330), that is responsive to the counter, the ring signal and the user input, is programmed to allow the telephone to ring if an incoming call has been detected and if more than the selected amount of time has passed since the user input was last asserted.
