Abstract: ABSTRACT OF THE DISCLOSURE         The electrode is self-supporting, inexpensive and is of the throwaway or non-rechargeable type utilizable in metal-air cells and batteries.  It comprises a readily corrodible, inexpensive current collector, preferably of iron or steel or copper, and an electrochemically active layer.  The current collector has a hydrophobic coating, preferably of polytetra-fluoroethylene or the like, to at least partially protect it from corrosion,  The electrochemically active layer is secured to the current collector through the hydrophobic coating so as to form therewith a self-supporting electrode.  This layer com-prises particulate carbon catalyst with a hydrophobic binder compatible with the hydrophobic coating on the collector and fused thereto and present in an amount sufficient to bind the carbon particles into a coherent layer.  The binder aids the coating in protecting the collector,  The use of expensive, sep-arately generated, thin hydrophobic films placed into the struct-ure during its formation is totally obviated so that a lower cost is achieved while still providing an electrode having suitable electrochemical activity.

Abstract: THERMAL MODEL FOR ELECTRICAL APPARATUS         ABSTRACT OF THE DISCLOSURE          A thermal model of an electric apparatus, such as a transformer or motor, from which signals can be obtained representing temperatures of the conductors and of the adjacent core material.  A first and a second register hold values representing conductor temperature and core material temperature. A sensor and a digital-to-analog converter provide a digital signal representing current in the conductors and this is added to the first register to represent heat generated in the conductors.  Values are determined for both heat transferred from the conductors and heat transferred into the core based on the difference in values in the first and second registers.  The first value is subtracted from the first register and the second value is added to the second register.  Another value is determined for heat transferred from the core material, based on the difference between the value in the second register and a reference value, and this is subtracted from the second register.  This last value may be modified when the electric apparatus is a motor to provide for a condition of heat loss when the motor is rotating and when it is stationary.  The first and second registers thus have available at all times stored values representing conductor temperature and core or average temperature and these temperatures can be used to interrupt the supply of power to the apparatus when predetermined levels are exceeded.

Abstract: ABSTRACT OF THE DISCLOSURE Weakly basic ion exchange resins are used to remove iron compounds in anhydrous or substantially anhydrous organic systems such as phenolic process streams.  The resins may be either in the form of a weak salt such as the amine hydrochloride or may be a protonated amine carboxylic acid in the acidic form. In either case, we have determined that the active site does not perform in a conventional ion exchange manner but rather forms a complex with the entire iron compound molecule.  While the complex is formed in a waterless or almost waterless system, it may be regenerated in an aqueous system.
