Ø A Ø B H 37 Patents: US 7,114,710 B2 - German Patent No. 102 49 647.1 - German Patent No. 102 49 647 Active Isolation System AIS™ Transportation and centering screw Leveling screw Air-Bearing Air-tube Design The pneumatic horizontal vibration isolator HAB TM is constructed of a cylindrical top and bottom housing. Air tubes placed into the annular space between the two housings provide the horizontal force to counter any relative movement between the two housings. The horizontal force or natural frequency of the HAB TM can be adjusted by changing the air pressure of these air tubes. A specially designed air bearing handles the vertical load and provides friction free smooth horizontal movement between the top and bottom housings. Advantages of new HAB™ in comparison to conventional air-springs: Adjustable horizontal natural frequency. Adjustable horizontal dampening. Very low natural frequency / very efficient vibration isolation. Friction free operation, no stick-slip or hysteresis. When used as part of the AIS TM System no amplification at resonance Very high dampening, Minimum settling time, Excellent level accuracy.
