Abstract: An improved process for inhibiting calcium carbonate scaling in aqueous systems such as that employed in the kraft process for the production of wood pulp. Such an improved process is achieved by the addition to the system of at least one antiscalant comprising at least one monomer unit derived from the group consisting of 1,2-dihydroxy-3-butene, N-(hydroxymethyl) acrylamide, and N-(sulfomethyl) acrylamide, and at least one monomer unit derived from the group consisting of maleic acid, acrylic acid, acrylamide, methacrylic acid, itaconic acid, vinyl sulfonic acid, styrene sulfonic acid, N-tertbutylacrylamide, butoxymethylacrylamide, N,N-dimethylacrylamide, sodium acrylamidomethyl propane sulfonic acid, and salts thereof, with the proviso that said polymers do not contain the monomer unit --(CH.sub.2 --CH.dbd.CH--CH.sub.2 --O)--.

Abstract: Flexible convoluted conduit covered with braid made by cold forming the braid to an end of the conduit. Cold forming can involve magneforming. Resulting conduit is not brazed, welded, or annealed, thereby facilitating construction of convoluted conduits with higher working pressures and/or less braid material.

Abstract: Convoluted conduit covered with braid made by cold forming the braid to an end conduit or an end section of the convoluted conduit. Cold forming can involve magneforming. Resulting conduit need not be brazed, welded, or annealed, thereby facilitating construction of convoluted conduits with higher working pressures and/or less braid material.

Abstract: A detector system for providing a plurality of output beams for monitoring the output beam of a laser system. The detector system includes a refractive element having a pair of opposing spaced-apart faces. The laser beam enters the refractive element where it undergoes multiple internal reflections off of the faces. A portion of the beam is transmitted out of the refractive element at each of the reflections to form a plurality of increasingly attenuated output beams having different power intensities from each other. A plurality of detectors are positioned for measuring the different beam characteristics of the plurality of attenuated output beams, which correspond to the beam characteristics of the laser output beam.

Abstract: An inspection/detection system is for use in forensic applications. The inspection/detection system includes a carrying case which has a cover-lid, a light module and a power supply module. The carrying case is a rectangular box with a closed end and an open end to which the cover-lid is hingedly coupled. The light module is mounted within the carrying case and has an output aperture. The light module may be an argon laser head. The power supply module is disposed within the carrying case and energizes the light module to generate light energy therefrom. The inspection/detection system also includes an optical connector and a shutter assembly. The optical connector is optically coupled to the output aperture. The shutter assembly is optically coupled to the optical connector. The inspection/detection system further includes a flexible optical fiber, a remote control handpiece and a heat exchanger. The flexible optical fiber cable is optically coupled to the optical connector.
