    Abstract: A trowel for smoothing mortar coated on the interior wall of a pipe, including an elastic member for receiving pressurized air and inflating to a diameter less than the interior of the pipe. A blade assembly is connected to and extends from the elastic member, and defines an outer circular surface substantially corresponding to the coated interior diameter of the pipe for engaging and smoothing said mortar. The blade assembly is constructed and arranged to accommodate variances in the inner diameter of the pipeline.

    Abstract: A pipeline pig for lining pipe lines with an internal coating of a solidifying plastic composition with which the pipe line is spread by means of the pig, the pipeline pig having at least one spreader body and at least one forward and one rear guide body. The guide body comprises at least three narrow, resiliently elastic guide pieces bent into U-form comprising a middle part with forward and rear U-legs at the ends and rounded transitions from the middle part to the U-legs, the middle parts extending in the axial direction of the pipeline pig for guidance of the pipeline pig in the pipe line by abutment on the inner wall of the pipe line and being offset in relation to one another in the circumferential direction, the forward U-legs being non-displaceably secured in the axial direction in the pig and the rear U-legs being displaceably mounted in the axial direction in the pig and secured to a common bearing.

    Abstract: A method and apparatus for dispensing a fluid in a conduit and more particularly for dispensing lubricant within an electrical conduit for facilitating pulling electrical cables through the conduit. The apparatus is in the form of a cartridge disposed in the conduit at an end thereof. The cartridge is made of a pair of sealed and separable members. One of the members is a flanged sleeve forming the casing of the cartridge, in which is coaxially disposed the separable member forming a tubular support member or carrier for a mass of resilient and absorbent lubricant impregnated porous material compressibly packed between the inner surface of the sleeve casing and the carrier. A cable pulling strand, or fishtape, is passed through the tubular carrier, and the cables to be pulled through the conduit are attached to the end of the fishtape. A plug inserted in the open end of the tubular carrier prevents the fishtape and the cables attached thereto from being pulled back through the carrier. The carrier separates from the sleeve casing when a pull is exerted on the other end of the fishtape. The mass of resilient and absorbent material supported by the carrier expands to the inner diameter of the conduit when leaving the sleeve casing and absorbs part of an additional supply of lubricant contained in the cartridge. Pulling the lubricant-impregnated mass of resilient and absorbent material on the carrier ahead of the electrical cables coats the wall of the conduit with a film of lubricant.

    Abstract: A device is provided for lining pipes and the like with calcite. The device includes a reaction and mixing chamber in a U-shaped tube through which a supersaturated solution of calcium carbonate is circulated and delivered through the pipe to be lined. The solution is recycled from the pipe through the reaction chamber where calcium chloride and sodium carbonate are added to maintain the supersaturated conditions. Portions of municipal water main systems can be closed off, lined quickly and put back in service.
