Title: Method and apparatus for preventing voltage extremes in an electrolytic cell having automatic adjusting of the anode-cathode spacing
Inventor: WARREN JACK
IPC: C25B15/04
Filed: 1974-12-12
Granted: 1978-10-10
Abstract: ABSTRACT OF THE DISCLOSURE         An improved method and apparatus for protecting electrolytic cells having an automatic anode adjustment device from over- and/or undervoltages.  The cell voltage is measured and displayed.  Set points are established for high and/or low voltage limits and these set points axe sensed by a sensing device.  The sensing device is connected to the automatic anode adjustment system.  When a voltage limit set point is reached, the sensing device operates to prevent further automatic anode adjustment of the cells' anodes.  Electrodes are protected against voltage extremes caused, for example, by malfunctioning of components of the automatic anode adjustment device.

Abstract: ELECTROLYTIC PRODUCTION OF CHLORINE DIOXIDE, CHLORINE, ALKALI METAL HYDROXIDE AND HYDROGEN     ABSTRACT OF THE DISCLOSURE     Chlorine dioxide, chlorine, alkali metal hydroxide and hydrogen are produced from hydrogen chloride, alkali metal chlorate, alkali metal chloride and water in a three compartment electrolytic cell in which a buffer compartment between the anode and cathode compartments is separated from the anode compartment by an anion-active permselective membrane and from the cathode compartment by a cation-active permselective membrane.          Hydrogen chloride is fed to the anode compartment, aqueous alkali metal chlorate and chloride are fed to the buffer compart-ment and water is fed to the cathode compartment, with chlorine dioxide and chlorine being taken off from the anode compartment while hydrogen and alkali metal hydroxide substantially free of alkali metal chloride are produced in and removed from the cathode compartment.          The products of the process are obtained in a single vessel in forms suitable for use in pulping wood and bleaching wood pulp without production of undesirable byproducts that create disposal problems or require further processing for conversion to useful products.

Abstract: METHOD OF CONTROLING LOCOMOTIVE WHEEL SLIP  Abstract of the Disclosure A method and apparatus are disclosed for controlling the wheel slip of an electric or diesel electric locomotive such that optimum wheel adhesion may be attained.  A certain characteristic of a series traction motor, specifically the back emf per rpm versus motor current (E/n vs. I), forms the basis for a voltage control which limits the voltage (V) supply to each motor to a value which will limit the maximum percentage wheel slip.  The selected limit value of wheel slip is great enough to encompass the conditions of maximum adhesion under most rail conditions.  By combining the E/n with the motor IR drop, motor current, and a locomotive speed signal, the idealized voltage V for a non-slip condition is derived,  This voltage is increased by a factor representing the desired maximum percentage slip to obtain the limiting voltage which may be supplied to the motor.          A current maximizing circuit is included to decrease the allowed percent slip from the maximum preselected value to a value which provides the maximum motor current to obtain maximum traction.

Abstract: Abstract of the Disclosure A recent development for manufacturing blankets of mineral fibers includes a system comprising a plurality of fiber forming and collecting modules spaced along a process line, each module designed to produce a relatively thin web of intertangeled fibers and to deliver the thin web onto a common transfer conveyer to produce a plurality of superposed webs which can later be further processed to form a thick, uniform, mineral fiber blanket.  The present invention provides an improvement in the above described system by permitting one or more of the modules to be operated independently of the remaining modules resulting in the manufacture of one or more secondary products when the primary product being made on the main transfer conveyer requires the operation of less than all the modules in the process line.  The improved system includes means for removing a web from the collecting conveyer of a module prior to its being delivered to the transfer conveyer, means for elevating the web to the fiberizing level of the system, means for cutting the web into desired lengths, and means for accumulating the cut lengths into a form suitable for packaging, storage, and shipment. The improved system can optionally also include searing rolls to at least partially cure the binder in the web prior to elevating the web to the fiberizing level, slitting knives for edged trimming and slitting the web into desired widths, and other conventional web treating and laminating equipment.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention provides a process for preventing the generation of a mist of electrolyte in the electrowinning metal recovery which is carried out by using an aqueous solution of a metal salt as an electrolyte and an insoluble electrode, wherein the electrode is surrounded with an inert woven fabric screen over the effective area of the electrode plate including the bottom edge of the electrode plate, up to a position above the level of electrolyte, in parallel with and in the vicinity of the electrode plate.  The present invention also provides a means for recovering gas generated on the electrode, wherein part of an electrode beam, except for an electric contact part, and an elec-trode plate surrounded with an inert woven fabric screen are cover-ed and sealed with an inert, gas-impermeable film in such a manner that the film is close to the outer sides of the screen and the lower ends of the film is extended below the level of electrolyte, thereby recovering gases generated on the electrode and escaping through the mesh of the fabric screen through a gas outlet.

Abstract: ABSTRACT OF THE DISCLOSURE      This invention discloses a novel teaching aid for demonstrating the component pure spectral colours of white light and the effect of selective recombination thereof.  It utilizes the diffraction principle to produce a spectrum fro white light and selectively filters the spectrum.  By splitting the filtered light prior to recombination, it is possible to project an image of the selective filter and the recombined selectively filtered light adjacent to each other on a projection screen. Thus, the effects of the variation of the filter is shown directly by a variation in the colour and intensity of the recombined light.  This novel device provides a compact design of rather simple construction which clearly demonstrates the aforenoted principles and is an excellent teaching aid.
