Claims

1. A PORTABLE COMBINED POWER UNIT-LOAD UNIT ASSEMBLY, COMPRISING, IN COMBINATION, A POWER UNIT FORMED WITH A SURFACE PORTION AND INCLUDING A STORAGE BATTERY AND PRONG MEANS PROJECTING THROUGH SAID SURFACE PORTION AND ELECTRICALLY CONNECTED TO SAID STORAGE BATTERY FOR CONNECTING SAID POWER UNIT BY SAID PRONG MEANS TO SAID LOAD UNIT, AND, ALTERNATIVELY, TO A SOURCE OF ELECTRIC ENERGY IN SUCH A MANNER THAT SAID STORAGE BATTERY IS CHARGED THEREBY;

THE ELECTRICAL CONNECTION BETWEEN SAID PRONG MEANS AND SAID BATTERY INCLUDING TWO RECTIFIER MEANS, TWO CAPACITOR MEANS, AND MEANS ELECTRICALLY INTERCONNECTING SAID PRONG MEANS WITH SAID BATTERY, SAID RECTIFIER MEANS AND SAID CAPACITOR MEANS TO PROVIDE FOR THE BATTERY A FULL-WAVE RECTIFICATION OF THE CHARGING VOLTAGE APPLIED ACROSS SAID PRONG MEANS WITH VOLTAGE DROP ACROSS SAID CAPACITOR MEANS AND TO CONSTITUTE, DURING RECTIFICATION OF ONE-HALF OF THE APPLIED ALTERNATING VOLTAGE, ONE OF SAID CAPACITOR MEANS A CURRENT-LIMITING IMPEDANCE FOR THE CHARGING CURRENT AND THE OTHER OF SAID CAPACITOR MEANS A CHARGING CAPACITOR CONNECTED ACROSS SAID BATTERY, AND DURING RECTIFICATION OF THE OTHER HALF OF THE APPLIED ALTERNATING VOLTAGE, THE OTHER OF SAID CAPACITOR MEANS A CURRENT-LIMITING IMPEDANCE FOR THE CHARGING CURRENT AND THE SAID ONE OF SAID CAPACITOR
