drag, and the mass-arm length relationships of the escapement mechanism. An ascent rate of 

 about two to four feet per second will result from this free-running condition. The other two 

 positions of the controller result in the actuation moving the escapement arm upward or down- 

 ward, respectively, and thus permitting the ratchet gear to move one tooth (7 in.). Actuation 

 up and down of the control, thus, permits the PTC to be raised slowly and positively to the 

 surface. Three ports were incorporated into the structure to permit observations of the occu- 

 pants. Internal pressure gages were so placed as to permit their observation from outside as 

 well as inside.
