In Fig. 6 is illustrated a large magnet clutch designed for therapid reversal of a very heavy load, a considerable amount of heatnecessarily being generated at the friction surfaces at each reversal.The friction element of this clutch is composed of a plurality of fric-tion plates, keyed alternately to the driving and driven elements andconstantly bathed in oil, which serves to lubricate the plates and atthe same time transmits the heat to the retaining case, where it isreadily dissipated at the corrugated surface of the case. construction. A 40-cell automobile battery is connected to a charg-ing board to show the conditions under variable rate of charge anddischarge, and demonstrates the high rates which can be used with-out effecting the battery. In one show case are the different partsused in the construction of the ce
