This appeared asymmetry of the clothing outfit. The third jump confirmed the advantages of- the hermetic helmet, leaving open the problem as to whether it should be kept on, until landing or removed'once the parachute was opened. Some of the parachutists maintained that the helmet prevented proper gaging of distance to the ground... It was finally decided toremove the glass immediately upon opening the parachutei since if the parachutist landed on his side, the air hose might becomelblocked and .,stop the oxygen flow. Hermetic helmets were worn on all subsequent flights. On 20 August 1957, a record delayed jump was made from an altitude of,15,383 m- by honorary Master of Sports N.

The dalculation-of this action is precisely the .most important and least clear problem in the theory of the measure- ment of gravity forces on sea.

The advantage was emphasised of constructing @pendulum instruments in a cardan suspension with a minimum natural frequency. , It is not advisable to apply a damping. device.of the cardan suspension, which is linked with the, ship. Methods were-develo-oed and investigated of evaluating the recordings of inclination-meters and accelero-imters for obtain- correction for the inclination and.the acceleration and appropriate calculations were made based on materials collected by marine gravimetric expeditions. It is concluded that it is in principle.possible to,effect pendulum measurements on surface ships provided that the,acceleration of the ship is below 20* gl; at larger accelerati -ons, considerable.difficulties occur. associated with the determination of the accelerations and inclinations.

Of the two pendulums used, the amplitude of one is assumed absolute zero, a reqULrement which may not always be easy to satisfy. The present article develop$ a more accurate solution of the cooscillation problem which takes into account the' friction-forces-acting on the two pendulums used in the resonance approach. The, general relationships*are derived and the arbitrary constants of integration are h determined. The determination of the oscillation.of the stand from the relations ips of amplitudes of the two pendulums is described and the simplest case of co- o5c illation determination is discussed. A-detailed discussion is given of some otI.-.er special cases. This comprehensive paper concludes with.a description-Of the',. @4 wo --6.
