摘要： A system for conversion of hydrostatic pressure variations of sea waves into useful energy is disclosed. The system is comprised of a sealed casing (12) with a membrane-like cover (16). The cover operates piston (52) under the pressure of the waves. The piston compresses air into vessel (22), from which it is discharged (86) to drive turbine (24) and produce electric energy (26). The piston (52) is recoiled back upwards by the second piston (56), reciprocable within the cylinder (58). The effective volume of the cylinder (58) is variable for counter-pressure adjustment purposes.

摘要： Sanitary-ware coupled to a mains water supply, the sanitary-ware including a flushing assembly including a tank having a first chamber having a first volume and an inlet, and a second chamber having an outlet and a second volume, larger than the volume of the first chamber; the inlet coupled to a source of water at high pressure receiving a first quantity of water at an inlet pressure from the source; and a pressure exchange mechanism disposed between the first chamber and the second chamber, wherein a first quantity of water in the first chamber causes a second quantity of water in the second chamber, larger than the first quantity, to be pushed out of the second chamber through the outlet at a pressure lower than the inlet pressure by the pressure exchange mechanism. Preferably, the source of water at high pressure is a mains water supply.
