    摘要: The invention is a method of making a foam filled honeycomb core structure comprising the steps of: 1) providing a honeycomb core billet; 2) reinforcing the honeycomb core with foam; 3) placing the foam filled billet in mold having a curved mold surface; 4) creep forming the foam filled billet to the general shape of the structure by applying a load to the foam filled billet; and 5) machining the creep formed billet to the actual shape of the structure.

    摘要: A system for pumping an abrasive or corrosive fluid at high pressure and with a variable delivery rate. The system comprises raising the pressure in a non-corrosive and non-abrasive liquid in a pressure raising means comprising pump means and at least two intermediate cylinders containing floating pistons. The pressure is transferred to the abrasive or corrosive fluid in pressure transfer vessels. A valve arrangement controls the flow of non-abrasive and non-corrosive liquid to the intermediate cylinders and return means are provided for returning the floating pistons after each stroke. The valve arrangement is controlled in dependence on the positions of the floating pistons in their intermediate cylinders.The system is particularly useful for supplying clay slurry to a high pressure plate filter press.
