20080265478 | WIND TURBINE SYSTEMS DAMPERS - A damper for a structural tower having a space frame construction for high elevation and heavy load applications is disclosed, with particular application directed to wind turbines. The structural tower includes one or more dampers for damping resonant vibrations or vibrations generated by non-periodic wind gusts or sustained high wind speeds. The wind tower damper includes a fluid damper comprising a housing, elastomeric chamber, piston and damping fluid, wherein relative motion between the first and second structural members drive the fluid moving piston to pump the fluid and thereby dissipate unwanted motion in the tower. | 10-30-2008 |
20090289472 | CONSTRUCTION VEHICLE CAB SUSPENSION MOUNT - A vehicle suspension mount for connection of a first vehicle body structure with a second vehicle body structure, the mount including a first outer container member, a second outer cap member, the second outer cap member having a nonelastomeric center axial shaft and an outer elastomeric cap with the outer elastomeric cap grounded radially outward to the first outer container member, the nonelastomeric center axial shaft longitudinally extending inward into the first outer container member along a shaft axis, with the nonelastomeric center shaft having a terminal end distal from the outer elastomeric cap. The first outer container member and the second outer cap member contain a suspension mount damping liquid, a suspension mount damping liquid damper pumper member, the suspension mount damping liquid damper pumper member fixed to the nonelastomeric center shaft proximate the terminal end, and an inner elastomeric bearing support assembly disposed in the first outer container member between the suspension mount damping liquid damper pumper member and the second outer cap member, the inner elastomeric bearing support assembly including an inner elastomeric member bonded with an inner nonelastomeric grounding member, the inner nonelastomeric grounding member grounding the inner elastomeric member with the first outer container member, with the inner elastomeric member supporting a low friction bearing against a bearing surface of the nonelastomeric center shaft, the low friction bearing in alignment with the nonelastomeric center axial shaft axis wherein the nonelastomeric center axial shaft translates along the low friction bearing with the suspension mount damping liquid damper pumper member pumping the suspension mount damping liquid. | 11-26-2009 |
20100296869 | POWERED CONSTRUCTION GROUND COMPACTOR AND METHOD OF MAKING - A powered construction ground compactor for use by a worker compacting a construction foundation material. The powered construction ground compactor includes a lower foundation interfacer for interfacer engaging the construction foundation to be compacted, a powered compacting large moving mass, the powered compacting large moving mass forcing the foundation interfacer into construction foundation material to be compacted, an upper handle for holding by the worker compacting the construction foundation material, a handle moving mass vibration absorber, the handle moving mass vibration absorber including a moving mass, the moving mass movingly coupled to the upper handle wherein the moving mass oscillates relative to said compacting moving mass. | 11-25-2010 |
20100314525 | Engine mounting system - An equipment engine mounting system/method for mounting an equipment engine to an equipment frame. The equipment engine mounting system includes a first engine mount disposed between the equipment engine and the equipment frame, including a first engine mount nonextensible inner member having an outer bonding surface. The first engine mount including a first engine mount nonextensible outer member, the first engine mount nonextensible outer member having an inner bonding surface. The first engine mount includes an intermediate elastomer between the first engine mount nonextensible inner member and the first engine mount nonextensible outer member, the first engine mount intermediate elastomer bonded to the first engine mount nonextensible inner member outer bonding surface and the first engine mount nonextensible outer member inner bonding surface. The first engine mount includes a liquid housing cavity, containing a first variable volume liquid chamber proximate the first engine mount nonextensible inner member and a second variable volume liquid chamber, distal from the first engine mount nonextensible inner member. The equipment engine mounting system includes a second engine mount disposed between the equipment engine and the equipment frame, the second engine mount including a second engine mount nonextensible frameside member and a second engine mount nonextensible engineside member, and a highly damped elastomer between the second engine mount nonextensible frameside member and the second engine mount nonextensible engineside member, with the engine mounting system mounts inhibiting a transmission of a vibration of the equipment engine to the equipment frame. | 12-16-2010 |
