Figure 14. Circuit for ballast control with combined
displacement and rate-of-ascent switches.
Figure 15 is a theoretical height-time curve, showing when
ballast would be dropped using such a control and the re-
sulting balloon behavior. During ascent the pressure pen is
kept off the commutator bar until Point l where it falls on-
to the low-altitude conducting segment. {The shelf has been
set so that the pen will fall onto the low-altitude segment in
order that a ballast signal will be received for a shortperiod
of time, indicating that the system is working properly. The
balloon rises and ballast flows until the pressure pen reaches
Point 2, the beginning of the region where both switches in
series control the ballast. As long as the balloon continues ·
to rise, no flow occurs. Should the maximum altitude be above
the control level • no ballast will flow until the balloon de-
scends to that point. Then, with both controls operating, bilast
will flow only on the descending and floating portions of the
flight below control level. A second course is illustrated,
wherein the ra·te-switch has failed. 'l'hE!re the balloon de-
scends to Point 2 and oscillates about this level, as a r~sult
