Abstract: MOTOR VEHICLE ELECTRICAL SYSTEM          Abstract of the Disclosure A motor vehicle electrical system which is capable of supplying both 12 and 24 volt loads.  A pair of 12 volt batteries are permanently connected in series and are charged in series under certain conditions of operation from a 24 volt charging system including an alternating current generator and a bridge rectifier.  The output voltage of the 24 volt charging system is maintained substantially constant by a voltage regulator con-nected with the field of the generator which senses and responds to the output voltage of the bridge rectifier that is applied to the series connected batteries and other 24 volt loads.  An auxiliary charging circuit is provided connected between one of the phase windings of the generator and the junction of the series connected batteries for, at times, supplying current to one of the batteries that supplies the 12 volt loads.  This cir-cuit includes a series connected silicon controlled rectifier and inductance.  The controlled rectifier is gated into conduction whenever the voltage at the junction of the two batteries drops below a voltage corresponding substantially to one-half of the output voltage of the bridge rectifier that feeds the 24 volt loads.

Abstract: ABSTRACT OF THE DISCLOSURE          The disclosure teaches a process for introducing a soluble, catalyst-containing material into a conducting particle, hydrophobic-bonded electrochemical cell electrode.          The process includes the step of dissolving the soluble catalyst-containing material in a liquid solution of dissimilar liquids which liquid solution has the following characteristics:          It is capable of wetting the hydrophobic bonding material of the electrode at a first composition range of the liquids.  It is incapable of wetting the hydrophobic bonding material at a second composition range of the liquids; and it is capable of changing from the first composition range to the second composi-tion range on evaporation of the solution.  The electrode is contacted by the soluble catalyst-containing material dissolved in the liquid solution in the first composition range, whereby the solution enters the hydrophobic and hydrophilic regions of the electrode structure.  The solution is evaporated to change its composition from the first composition range to the second composition range whereby the solution withdraws from the hydrophobic bonding material of the electrode structure.

Abstract: ABSTRACT   An improved process for separating a fluid feed stream containing a mixture of substances (fructose and dextrose solutions) into a plurality of streams richer in one or more of the substances by alternately passing the mixed fluid feed stream and an elution fluid stream through a chromatographic separation column to obtain an effluent stream.  She column has a chamber containing an adsorbent which has a selective affinity for one of the substances in the fluid feed stream so that portions of the effluent stream have higher concentrations of one of the substances.          Thereafter, separate successive portions are collected of the effluent stream having higher concentrations of at least one of the substances.  The process involves first densely packing the adsorbent in the chamber of the separ-ation column, and the chamber is devoid of any internal flow distributing structure.  The adsorbent is such that it contracts to a reduced volume in the presence of a selected reagent, and swells when the excess of concen-trated reagent is removed.  The adsorbent is disposed in the separation column chamber in its reduced volume condition and is effectively confined in the chamber of the separation column.  She excess of the concentrated reagent is removed from the adsorbent so that the adsor-bent swells to completely and uniformly pack the separa-tion column chamber and thus eliminates channeling and turbulent flow, and improves the uniformity of the cross-sectional flow rate across the column chamber.  The pro-cess provides one output stream rich in fructose and another output stream rich in dextrose.
