Abstract: A method and apparatus for repairing or relining an underground pipeline without having to excavate the pipe is enabled by attaching an expandable sealing unit to the end of a predetermined length of flexible tubing and feeding it through the pipeline. The flexible tubing is fed through the existing pipeline from a point beyond where the existing pipeline exits the earth, usually within the basement of a building. Once positioned in the desired location, the expandable sealing unit is expanded to form a tight seal at the desired location within the pipe by means of heating the expandable sealing unit by a heating unit connected to the source of energy through electrical conductors which pass through the flexible tubing.

Abstract: A novel cut pile fabric (10) and a method of making same is disclosed. The cut pile fabric (10) includes a needled non-woven batt (14) of staple fibers (12) that is processed on a texturizing needle loom (17) from one surface (20) (called a back surface) thereof to form texturized loops (18) on the other surface (22) (called a face surface) of said batt (14). The non-textured back surface (20) of the batt (14) has a backing (24) applied thereto which may be of latex, or the like, with the texturized loops (18) being tigered by a tigering roll (28) to cut, break or fracture a high percentage of the loops.

A novel method of making a fabric is provided and comprises needling (15) the non-woven batt, attaching the cloth or film (22) to the batt, needling clustered loops (34,35) from the non-woven fibers of the batt through the cloth or film (22) to define a pattern of loops with the cloth or film ( 22) visible between the clustered loops, and optionally backing the non-woven batt.

Abstract: A bioluminescent assay for ATP in water borne bacteria is made by adding nitric acid to a water sample with concentrated bacteria to rupture the bacterial cells. The sample is diluted with sterile, deionized water, then mixed with a luciferase-luciferin mixture and the resulting light output of the bioluminescent reaction is measured and correlated with bacteria present. A standard and a blank also are processed so that the light output can be correlated to bacteria in the sample and system "noise" can be substracted from the readings.A chemiluminescent assay for iron porphyrins in water borne bacteria is made by adding luminol reagent to a water sample with concentrated bacteria and measuring the resulting light output of the chemiluminescent reaction.
