Title: Long-life alkaline primary battery
Inventor: RUEETSCHI PAUL
IPC: H01M6/12
Filed: 1977-04-27
Granted: 1980-12-02
Abstract: ABSTRACT OF THE DISCLOSURE:         The invention relates to an alkaline primary battery of the type having a negative electrode containing cadmium or amal-gamated zinc and a positive electrode containing monovalent silver oxide, mercuric oxide, or mixtures of these oxides with manganese dioxide, the positive electrode having an electrochemically active surface area facing the negative electrode.  At positive electrodes, self-discharge can be caused by the solubility of the active mate-rial.  The alkaline primary battery of the invention is designed to reduce this type of self-discharge, without impairing the in-ternal resistance of the battery and, to this end, comprises at least one electrically conductive, microporous, electrolyte-saturated, optically opaque filter-electrode which covers the entire electrochemically active surface area of the positive elec-trode, the filter electrode either containing no monovalent silver oxide and no mercuric oxide, or containing at most a substantially smaller amount of the oxides per unit volume than the positive electrode; the filter electrode contains as principal constituent electrically conducting material which is not corroded, oxidized or dissolved in alkaline electrolytes at the given potential of the positive electrode, and is in electrical contact with the positive electrode.

Abstract: Abstract of the Disclosure This invention relates to a process for preparing urea by reacting NH3 and CO2 at an elevated temperature and pressure whereby urea is formed in a synthesis zone in the form of a urea synthesis solution when NH3 and CO2 are reacted at a pressure and temperature suitable for formation of urea. Ammonium carbamate is formed first which is then partly converted into urea and water,  Thus from the urea synthesis zone an aqueous urea synthesis solution with non-converted carbamate, and usually an excess amount of NH3, is obtained.  Non-converted carbamate and excess NH3 are removed from the urea synthesis solution, and usually recycled to the synthesis zone.  To effect such separation the urea synthesis solution can be expanded and heated in two or more steps so that the carbamate reverts into NH3 and CO2.  Alternatively the urea synthesis solution may, if necessary after partial expansion, be subjected to a stripping treatment with NH3 and/or CO2, with supply of heat and after expansion, reheated.  In most known processes, the mixtures of gas-eous NH3, CO2 and water vapour separated off in the successive steps are ab-sorbed and condensed and returned to the urea synthesis zone as an aqueous solution.  However, a disadvantage of returning non-converted NH3 and CO2 as a solution is that the water adversely affects the conversion of carbamate into urea, so that more carbamate must be decomposed and more steam is necessary for supplying the heat of decomposition.  This disadvantage is overcome by the present invention.  The process of the invention enables the decomposition of carbamate and the recycle of NH3 and CO2 to be carried out without undue energy requirement with a saving of investment costs.

Abstract: ABSTRACT OF THE DISCLOSURE         A single barrel puffer circuit interrupter is taught which has a thin fluorocarbon plastic liner for the single insulating barrel.  The fluorocarbon plastic liner is polytetrafluorethylene (TFE) sold under the trademark TEFLON. The fluorocarbon plastic material is disposed in the form of a wound overlapped thin film.  The film is etched so that an epoxy resin adhesive may be used for binding successive layers of the overlapping film one to the other and for binding the film to an outer sheel of fiber-glass which forms the remainder of the band.  The fluori-nated plastic is generally resistive to the detrimental effects of the presence of an electric arc within the barrel of the circuit interrupter.  Such effects include the heat of an electric arc, the current of the electric arc or the arc products which are formed by the use of sulfur hexa-fluoride gas in the puffer operation in the presence of the arc.
