The latter leads are connected to the control and suppressor grids of a pentode 60a, Fig. 3a, so that when the triggers associated with the closed tens and hundreds switches are both conducting in their right-hand sections (or in the left-hand sections in the case of the triggers MpTT9...
Three of the partial product plate groups have been advanced to represent the multiplicand, the groups in the hundreds and tens orders seven steps and the units order group five steps. In the hundreds order feeler 679 (Fig. 4) enters two steps in contacting the plate 538, positioning the ...
Also, during this same half revolution, parallel circuits will be completed through the other order of the multiplicand keys to enter a "5" in the tens order magnet 107R and "1", "3" and "4" in the ten thousands, thousands, and hundreds order magnets 10IL, so that at the ...
Thus the product is 3 thousands + 7 hundreds + 12 tens + 8 ones. The student then must regroup the tens so that the product is 3828. More simply, the regrouping can be done as the addition is completed. (Fig. 3) This trick produces correct products because multiplying by eleven is ...
If the digits occur in the tens, hundreds or thousands places obvious changes take place. Multiplication is effected by depression of the appropriate keys 103 in a multiplicand bank 101, Fig. 8, and a multiplier bank 102. In the diagrammatic Fig. 1 the keys appropriate to the multiplication...
The multiplicand register A comprises series of relays Aa (units), Ab (tens), Ac (hundreds), and Ad (thousands), each series comprising four relays, for example, 1Aa, 2Aa, 4Aa, 8Aa representing values 1, 2, 4, 8 respectively, which, energized singly or in combination may register ...
A branch connection 135 and contacts TP9 connect the hundreds brush UBa to a relay C ; a third branch connection 134 and contacts TP8, connect the thousands brush UB to relays A and B. None of the relay circuits will be completed if the multiplier contains more than three figures, relays...
