Abstract: ABSTRACT             This invention relates to apparatus for determining the amount of liquid in a tank by measuring the pressure at the bottom and at a height above the bottom of the tank, and provides apparatus for compensating for apparent volume measurement variations caused by expansion and contraction of the tank and liquid with variation in temperature.  A tube which expands in length at an exactly compensating rate varies the height of the second pressure sensor relative to the first.  A further embodiment is a pneumatic system which avoids the necessity to immerse the pressure sensor, and utilizes an inexpensive single differential pressure transducer instead of two, and which cancels out the effect of any changes in zero setting of the transducer, changes in sensitivity of the transducer, or changes in atmospheric pressure.

Abstract: Abstract Upon a spider with rigid arms (4) and thereon adjoining mounting plates (1) are placed spring bands (81,82,83).  These are supported on battens (12) on the mounting plates (1) and connected via screw bolts (20).  By means of the screw bolts (20) the spring tension of the leaf spring strips (71,72,73) can be varied. Upon this triangle of strips rests another spider, containing rigid arms (5) and mounting plates (2).  The contact site of the leaf spring sections (71,72,73) on the battens (12) is linear and in the same way there exists a linear resting of the arms (5) on the underlying strips.  The mounting plates (2) of the upper spider contain again  battens (12) and clamp bolts (20) forming a linear support.  The superposed spiders are guided against one another through sleeves (9), guide rod (10) and key (11).  Because of the fact that there exist leaf spring sections, the mounting height of the vibration dampers is very small.  By means of the screw bolts (20) the spring tension can be changed in a very simple manner.  The vibration damper is intended as vibration insulator for mechanical vibrations of very low frequencies.

Abstract: ABSTRACT OF THE DISCLOSURE     A computer cooling system has gaseous refrigerant compressed in a compressor and delivered to a first stage condenser.  The first stage condenser includes a heat exchanger through which return coolant from the building heating system circulates to partially condense the gaseous refrigerant. The partially condensed refrigerant is directed to a second stage condenser wherein a portion of the refrigerant is diverted and flashed through an expan-sion valve into the second stage condenser to fully condense the nondiverted portion of the refrigerant before delivering it to the cooling coils of the computer.  A pressure regulator valve controls the pressure and temperature of the diverted refrigerant in the second stage condenser to ensure that the nondiverted refrigerant is fully condensed.  The used diverted refrigerant is discharged from the second stage condenser through the pressure regulator valve into an accumulator which also collects return coolant from the cooling coils of the computer.  The used coolant is delivered from the accumulator back to the compressor through a main return conduit.

Abstract: ABSTRACT          The working piston (15) in the cylinder (1) is acted upon key pressure fluid only on one side, while the return movement of the piston is produced by reaction forces (R).  The pressure fluid feed and the pressure fluid discharge are effected by way of separate conduits (9, 10) so that there is a continuous interchange of pressure fluid in the cylinder (1).          When the maximum piston stroke position is reached, pressure fluid can flow out of the cylinder (1), irrespective of the control position of the control device (2).  In both limit positions of the piston (15), the movement of the piston is braked by a mechanical damping means (18).
