Abstract: A method and apparatus for performing maintenance on sewer pipes using a thermal sensor. The method and apparatus may be applied to the reinstatement of lateral openings after a liner has been installed in a main pipe. The thermal sensor detects the location of the lateral openings by sensing the thermal conditions of the liner. The thermal condition of the portions of the liner that cover the lateral openings is different from the thermal condition of the rest of the liner. The apparatus and method is also applicable to detecting groundwater leaks in the main pipe, and is also applicable to inspecting exothermic chemical reactions in the main pipe, such as exothermic grout or epoxy used to seal the liner in the main pipe. The thermal sensor may be integrated into a camera assembly that includes a visual camera at one end and the thermal sensor at the other end. The visual camera is useful in those portions of the main pipe that are full of water.

Abstract: The present invention relates to the generation of transgenic avians and the production of recombinant proteins. More particularly, the invention relates to the enhanced transduction of avian cells by exogenous genetic material so that the genetic material is incorporated into an avian genome in such a way that the modification becomes integrated into the germline and results in expression of the encoded protein within the avian egg.

Abstract: A communication system utilizes an open system network protocol, such as the Transmission Control Protocol/Internet Protocol (TCP/IP), to transport Intelligent Network signaling messages from an SS7 network to a service provider which is not directly linked to the SS7 network. A gateway/bridge is provided between the SS7 network and a network which operates in accordance with an Internet protocol to transform Internet protocol messages, such as TCP/IP format messages, into SS7 format, and vice versa. In this way, an Internet protocol network may be used to transport Intelligent Network signaling messages between an SS7 network and a non-SS7 network service provider.

Abstract: A self-propelled lateral inspection apparatus includes a body, a main camera fixed to the body, and a lateral camera movable with respect to the body into a lateral sewer pipe. A low frequency beacon is carried by the lateral camera or may be provided separately from the lateral camera. The beacon may be used to determine the position of the lateral camera in the lateral sewer pipe, or to map the lateral sewer pipe. A picture-in-picture processor is carried by the body, and permits an above-ground user to view video images from both the main and lateral cameras simultaneously on a single monitor screen.

Abstract: A telecommunication system network having a public telephonic network switch which communicates signaling information in accordance with Signaling System 7 protocol with a signal transfer point. A primary message signaling interface at the public telephonic network switch receives signaling information under normal operating conditions via a link set from the signal transfer point. Another secondary message signaling interface at the same network switch receives signaling information via another link set parallel to the one link set from the signal transfer point upon the occurrence of certain preselected conditions and in which both link sets terminate on the same pair of signaling point codes.

Abstract: A method for blast cleaning metal and fixing the hazardous waste generated by blast cleaning. An abrasive cement in a sufficient amount is combined with the blast cleaning process, thereby reducing the leachability of the heavy metals and producing non-hazardous abrasive waste.
