Abstract: An inspection station and process for pipe or other ferromagnetic articles utilizes a generally straight flux field amplifier made of a multi-stranded cable surrounded by non-conducting resin, for inducing transverse lines of magnetic force. The flux field amplifier is surrounded by a coil which is also energized to make longitudinal lines of force; the two types of lines of force are vectored. The pipe or other ferromagnetic article is sprayed with UV-sensitive magnetic particles in a more or less conventional manner to display the vectored lines of force together with any flaws in the metal. The cable core of the flux field amplifier does not need a cooling system and is able to last longer than conventional solid cores.

Abstract: A method for calibrating a personal air sampler. A desired flow rate is set, the actual rate measured and recorded through a plurality of runs, the results are automatically averaged and compared to the desired flow and the pump is automatically adjusted accordingly. The process may be repeated for a plurality of selected flow rates, and a best-fit curve computed to cover the entire range. Stability is tested by a series of sets of runs to determine erratic behavior, and an overall calibration is conducted by performing such a series of runs at each of several set point flows.

Abstract: Very dry air is made for drying grain and other particulates. The air is dried by first cooling under pressure to remove moisture, then contacted with a drying device such as a vessel containing desiccant, then heated and released into a bed of particulates.

Abstract: Radar is used to measure not only the level of slag on molten steel but also its thickness; the measurement is used to calculate the volume of slag, and, in turn the amount of additives for slag treatment. Time-of-flight data are used to identify peaks representing the distances of the surfaces of the slag and the surface of the underlying steel. The concept is applicable to other materials of differing composition, and particularly where the underlying material is relatively more conductive than the overlying material.

Abstract: The invention is directed to corrosion and wear resistant metallic coatings containing nickel and boron. The coatings are preferably deposited on catalytically active substrates from an electroless coating bath containing nickel ions, lead tungstate as a stabilizer, a metal ion complexing agent, and a borohydride reducing agent, at a pH of about 10 to about 14. With post-coating heat treatment the coated surfaces exhibit hardness levels as high as about 2200 Knoop.

Abstract: Compositions including d-limonene are used to loosen adhesive bandages on humans. Preferred compositions include certain hydrogenated naphthenes and isoparaffins.

Abstract: A hair curler has a support and a sheath thereon containing a gel comprising a humectant, water, and a crosslinked water soluble polymer. The curler may be heated in a microwave oven; it emits moist heat during use and reabsorbs moisture from the atmosphere between uses.

Abstract: Method and composition for gel formation in hydrocarbon recovery, in which an organic phosphate ester is gelled by a novel activator composition comprising iron sulfate, dibutylaminoethanol, and a phosphate surfactant.

Abstract: A conveyor unit for a high wall mining system; a mining system employing a train of such units. The conveyor units are pushed in tandem into the mine. The system contemplates a motor mounted on a cutter at the head of the train; through a series of shafts and clutches, serially through the train of conveyor units, rotation power is transferred mechanically from the motor to turn the conveyor belts of the individual units. The mining system includes a preferred coupling/clutch apparatus and a launch vehicle for adding conveyor units to the train which has the ability to start the rotation of the conveyor belt on the new unit as it is added.

Abstract: A fishing lure comprises a lure body and at least one pair of arms configured to simulate the belligerent position of the raised upper arms and suspended lower arms of a crustacean.

Abstract: A brake and turn signal circuit permits a brake lamp to be used as a turn signal when both the brakes and turn signal are applied. Certain of the lamps may be caused to blink in a predetermined period and sequence particularly when both the brake and turn signals are actuated.

Abstract: Continuous electrolytic tin plating is accomplished in a bath containing 90-160 g/L sulfuric acid, 4-70 g/L tin ion and a grain refiner, and 1-4% nonylphenol ethoxylated with 8-10 ethylene oxide groups, having a weight average molecular weight of 616.+-.18, at a speed of 900-1600 feet per minute and a current density as much as 1500 amperes per square foot or more.

Abstract: Copolymers are disclosed of lower alpha-olefins and HALS-containing monomers, typically 1-(10-undecenyl)-2,2,6,6-tetramethylpiperidine. They may be used for light or heat stabilizing, by themselves or in blends with other polymers.

Abstract: A method for concentrating airborne particles and microorganisms by injecting them into a swirling air flow from where they are removed into one or more receiving tubes. The swirling air motion and the aerosol injection into it are achieved by pushing or drawing the airborne particles and microorganisms through one or more nozzles that are directed at an angle towards the surface of the containment vessel. The ratio of air flow rate into the vessel to the air flow rate through the receiving tube is equal to the maximum aerosol concentrating ratio desired.

Abstract: A method for the collection of solid or liquid particles suspended in air (aerosol). The method involves abstracting a quantity of air through a curved, porous plate with evenly spaced holes which are designed to give an accurate sample of the particle content over defined size ranges. This method differs from similar methods in that it (1) provides a minimal bias in the results from the effects of ambient air velocity or direction, (2) provides a more even distribution of particles over a collection medium, and (3) enables exclusion of particles exceeding defined upper size limits.

Abstract: An aerosol sampler for use with a source of vacuum. Air is drawn through a perforated hemisphere, directing small particles and aerosols for collection on a filter surface downstream of the hemisphere. A high collection efficiency is demonstrated.
