The pipe contour gauge is a device used to determine a diameter of a pipe or other object. The pipe contour gauge is constructed of a contour base from which a plurality of tines is able to move. Each of the plurality of tines is generally parallel with adjacent ones of the plurality of tines. Moreover, each of the plurality of tines is able to move independent of any remaining ones of the plurality of tines. Each of the plurality of tines is able to move up or down with respect to the contour base. The plurality of tines is adapted to interface with a surface of an object in order to form a profile that is compared with a chart outlining different diameters. The chart that outlines different diameters is used to decipher a size of a pipe or cylindrically-shaped object.

An electrokinetic display system in which zones or patterns of different chemical concentrations and gradients associated therewith are displayed in an electrochemical cell. The electrolyte contains reagents which take part in a reversible reaction during electrolysis. The reagents are self-indicating or include an indicator, or can be mixtures of both. Gas evolved at the electrodes is prevented from mixing the electrolyte too vigorously. D.C. current is passed between the cell electrodes in one direction long enough to establish a visible flow in the electrolyte. The use of reagents which take part in redox reactions or in which a reversible change in pH takes place is set forth. In a preferred embodiment, the active species in the electrolyte including the electrolysis reaction products are accelerated by a magnetic field transverse to the electric current path. Arrangements for widely varying the visible or multicolored eddy current patterns generated are set forth including moving the magnetic field, varying the current as by reversing and/or interrupting the current, and using alternating current. Also set forth are arrangements for excluding pH or redox indictors from the region of the electrodes.

An electrical plasma discharge is established between adjacent tubular electrodes of an electrode structure having a stacked array of rows of tubular electrodes of opposite polarity row-by-row. A substrate is moved through the electrode structure along several paths of travel such that the electrical plasma discharge is substantially parallel to one or both surfaces of the moving substrate. During the electrical discharge, the electrodes are cooled by flowing coolant therethrough.
