October 27, 1953 To C. K. Beck Copies to staff Subject.- Control Motores

Attention is directed to the fact, that when the representatives of the Brown Instrument division of the Minneapolis Honeywell company inspected the control mechanism which uses Brown motors , they told us that the motors were designed for operation with the shafts in a horizontal position. They were dubious of the satisfactory operation of these motors with their shafts oriented vertically. This matter was discussed at the time and the verdict was to leave the mechanism unchanged until after criticallity had been achieved, so that the change would not delay this procedure.

Now that critically has been achieved, it is recommended that the advice of the Brown representatives be followed, and that the mechanism be so modified that these motors operate in their normal horizontal shaft position.

It is important that this be done as soon as possible before activation of parts makes a long "cooling off" time necessary.
