The Instant-Multiplication (& 10s-Carry) Module (= "1x1-KOERPER")
=================================================================
PICTURE shows the  LEFT CRANK with the  VERTICAL LIFT TO FACTOR 9
                                        ( with a hidden support )

The TOOTH-BARS represent the values 9 .. 1   -   The INPUT-UNIT
put the TOOTH-WHEEL on this tooth-bar what represents its input
value. The movement of the tooth-bars will TURN the tooth-wheel.
This turn represents the input VALUE and is transfered into the
ARITHMETIC UNIT.

The MODULE consists of nine layers:  The upper one represents the
products 9 .. 1 with factor 1 - the next lower layer the products
with factor 2  a.s.o.  Because a product (e.g.  8 x 3 = 24 ) may
result in two digits, each layer ( factor > 1 ) has two "COMBS":
One for the  "ONES"- and one for its  "10s-CARRY"-REPRESENTATION.
The MODULE has to make MOVEMENTS IN  F O U R  COORDINATES ...

WITH THE LEFT CRANK:
--------------------
(1st) A VERTICAL LIFT setting the FACTOR = 1, or 2, ...  or 9
      in the hight, facing the tooth-bars with "10s-CARRY"-COMB.

<  E X A M P L E :  "MULTIPLICATION";  INPUT "8";  FACTOR "3"  >

WITH   O N E   T U R N   OF THE RIGHT CRANK:
--------------------------------------------
(2nd) HORIZONTAL SHIFT ( w. first HALF-TURN of the right crank )
      pushing the tooth-bars FORWARD ( w. activated arithmetic )
      as far as the "10s-CARRY"-COMB TOOTH-LENGHT
      ( the "ONES"-COMB fits in between the tooth-bars ! )
      and BACKWARD ( with disabled arithmetic unit )  let the
      tooth-bars moving back (spring forced) to its base-state.

<  THE ARITHMETIC UNIT DISPLAYS  "2"  AND MAKES A LEFT-SHIFT!  >

(3rd) HORIZONTAL SHIFT TO THE SIDE to bring the "ONES"-COMB
      in the position facing the tooth-bars

(4th) HORIZONTAL SHIFT ( w. second HALF-TURN of the right crank )
      pushing the tooth-bars FORWARD ( w. activated arithmetic )
      as far as the "ONES"-COMB TOOTH-LENGHT
      and BACKWARD ( with disabled arithmetic unit )  let the
      tooth-bars moving back (spring forced) to its base-state.

<  THE ARITHMETIC UNIT DISPLAYS  "4" ;   R E S U L T  =  "24"  >
