摘要： The present invention provides a high-pressure piston-cylinder assembly for compaction treatment comprising a cylinder comprising a plurality of sections which are longitudinally stacked and joined to form the cylinder; a piston configured for moving in and along the cylinder; and a base configured for being coupled with the cylinder to provide mechanical support to the cylinder; wherein each of the sections includes one or more releasing channels for releasing of liquid or gas fluid generated during compaction treatment. The high-pressure piston-cylinder assembly is sealed by one seal having a helical coiled sealing ring structure tightly encircling the piston, and another seal encircling a cylindrical sealing block protruded from the base and into the cylinder. The resulting piston-cylinder assembly can be more effectively manufactured, has better durability and tolerance in high-pressure operation.

摘要： A rapid mounting hallow wall anchor comprises a cleat with latching tooth and hanging flange, and a T-shaped anchor structure with latching cogs on its stem. The cleat comprises a tube with a flange near or at one end of the tube. There are latching teeth inside of the tube for engaging the latching cogs on the stem. The tube flange can be made to have a groove or hook on where objects can be hung. A cross bar joins one end of the stem with a cross bar hinge. The cross bar hinge allows the cross bar to be bended for insertion into a drilled hole in a plasterboard of a hallow wall.
