Abstract: ABSTRACT OF THE DISCLOSURE         A hydrostatic coupling device for rapidly releasable coupling of a first object immersed in water and another object resting on the sea bed.  The device comprises a seal mounted in a groove in the first object, which in use will be pressed against the other ob;ect.  The groove is formed as a closed loop delimit-ing a space at the surface of the first object facing the other object.  The seal is formed as a membrane mounted along its sides and dividing the groove into an outer part, open to the ambient water, and an inner part, which via a pipe can be connected to a reservoir above the water surface.  This reservoir maintains a liquid column pressure in the inner part, being a certain amount higher than the ambient water pressure.  Means are also arranged for pumping out water from the space delimited by the seal and both objects.

Abstract: ABSTRACT OF THE DISCLOSURE           An address comparator is disclosed which compares a write address value and a read address value for designating addresses in an elastic store circuit.          More specifically, the count output of a write address counter for counting a write clock signal is decoded by a write address decoder and the count output of a read address counter for counting a read clock signal is decoded by a read address decoder.  The respective decoded outputs are classified into a plurality of groups so as to be supplied to a logical circuit group.   The logical circuit group provides a signal for giving an alarm when the output address value of the write address counter is applied in a predetermined number of address groups including as the center of the address group to which the output address value of the read address counter belongs.          With such an arrangement, a timing difference between a write address value and a read address value can always be observed and,  even if the timing difference is changed rapidly, the timing difference entering the alarm zone can be detected.

Abstract: ABSTRACT OF THE DISCLOSURE A system for optimizing the RF input drive to a TWT amplifier over a frequency band of interest is disclosed. The system includes a microprocessor-based controller, an RF detector for detecting the TWT output, and a  variable attenuator for adjusting the input drive to the TWT.  The controller comprises an  analog-to-digital converter  for converting  the  video  detector  signals  and  providing digital RF level signals which are representative of  the TWT output power level.  Frequency data is also  provided to the  controller indicating  the  frequency of  the  RF exciter signals driving  the TWT.   The  controller  is, therefore,  provided   with   frequency  and   RF   level information, and is adapted to control the attenuator  to adjust the TWT input drive  for optimum TWT output.   The system is  operable in  a  calibration mode  wherein  the controller follows a  calibration algorithm to  determine the optimum attenuator setting, resulting in the  maximum RF output, for each  frequency of interest.  The  optimum attenuator setting is stored in an EEPROM for each  drive frequency.  The system  is further operable  in a  normal mode wherein the  controller sets the  attenuator at  the predetermined optimum  setting  for the  present  exciter frequency.
