Abstract: The present disclosure sets forth improvements in a cleaning procedure to clean electrodes exposed to hypochlorite in a measuring device. Typical measuring electrodes are made of platinum, gold, silver or other conductive metals. The electrode is dipped in a strong acid bath, a sacrificial oxide coated titanium electrode is placed in the bath and a DC power source is connected between the metal electrode requiring protection and the sacrificial electrode to create current flow until the surface has been treated. Current flow accomplishes the treatment after which the electrode can be removed and used in measuring hypochlorite concentration.

Abstract: The invention is a method for forming polymer films having a roughened surface using removable substrates comprising:(a) providing a removable substrate with a roughened surface;(b) forming a dispersion of a perfluorinated polymer containing sites convertible to ion exchange groups in a dispersant having: a boiling point less than about 110.degree. C.; a density of from about 1.55 to about 2.2; and a solubility parameter of from greater than about 7.1 to about 8.2 hildebrands;(c) depositing the dispersion onto the roughened, removable substrate;(d) removing the dispersant from the dispersion; and(e) removing the substrate.Particularly preferred as a dispersant is a compound represented by the general formula:XCF.sub.

Abstract: The present method and apparatus set forth an improved measuring device and system of measuring to determine hypochlorite concentration from electrolyte discharge from a chlor-alkali cell. In the preferred and illustrated embodiment, a container means suspended at the lower end of a wand captures electrolyte. It enables electrodes to be submerged with the electrolyte to obtain a measurement of the hypochlorite concentration. The electrodes include a current emitting electrode, a reference electrode and a gold sensing electrode having an external surface which is etched to increase the surface area and has a coating of hypochlorite thereon to maintain uniform calibration and measurement during operation.

Abstract: Unitary, cast structural element for solid polymer electrolyte filter pass electrolysis cell which incorporates into a single unit the central barrier between the peripheral boundaries for the adjacent anode compartment and adjacent cathode compartment of two electrolysis cells located on opposite sides of the central barrier. Also incorporated into the single cast structural element are anode bosses and cathode bosses extending outwardly from opposite sides of the central barrier. These bosses not only serve as mechanical support for their respective flat plate anode and cathode, but also they serve as stand-off means and electrical current collectors and dispersers from the cathode of one electrolysis cell to the anode of the next cell. Simplicity of design coupled with incorporation of many functional elements into one part eliminates many cell warpage problems, inherent high voltage problems and solid polymer electrolyte membrane "hot spot" problems.

Abstract: Novel vinyl ethers are prepared in decarboxylation reactions of novel acid fluoride compounds according to the following reaction: ##STR1## wherein a is 0 or an integer greater than 0;b is 0 or an integer greater than 0;n=1 or an integer greater than 1;R.sub.f and R.sub.f ' are independently selected from the group consisting of F, Cl, perfluoroalkyl or fluorochloroalkyl;X=F, Cl, Br or mixtures thereof when n>1X'=Cl or Br;Y is an acid group or an acid derivative easily convertible to an acid group;Z=F, Cl, Br, OH, NRR' or OA;R and R' are independently selected from the group consisting of hydrogen, an alkyl having one or more than one carbon atoms, and aryl; andA=alkali metal, quaternary nitrogen, or R.These vinyl ethers may be homopolymerized with themselves or copolymerized with other vinyl ethers.

Abstract: The invention is a separator-gas electrode combination comprising a separator having a first and a second face adapted to permit the flow of fluids or ions therethrough; a gas electrode adapted to permit a liquid and a gas to enter and exit the electrode and having at least a first and a second face; and a non-conductive self-draining member having a fluid outlet. The self-draining member has at least two faces; at least a portion of a first face contiguous to at least a portion of one face of the separator and at least a portion of a second face contiguous to at least a portion of one face of the gas electrode. The self-draining member has a plurality of interconnected passageways which are in fluid transferring communication with the separator, the gas electrode, and the fluid outlet and provide the major conduit therebetween.
