摘要： The prompt hot water and water conservation system includes a hot water supply pipe connected to a hot water heater outlet. A discharge faucet is connected to the supply pipe. A return pipe is connected to the supply pipe and to a hot water tank drain. The return pipe carries cooled water to the drain for reheating. Reheated water circulates into the supply pipe. A flow control device, in the return pipe, includes a chamber that houses a sphere. Return water flow moves the sphere toward a stop and permits unimpeded movement of water into the tank drain for reheating. When the faucet is opened, water flows from the tank drain into the flow control device. The sphere is moved to contact a small end of the chamber and substantially stop flow through the return pipe. Water is circulated through the system by increased density of cooled water.

摘要： The helical rotary cutter includes a cylinder with a plurality of grooves that extend from one cylinder end to the other end. Each groove has a leading groove wall and a trailing groove wall. The leading groove is in a first wall plane that extends outwardly away from the rotor axis in the direction of rotation and intersects the rotor axis. The trailing groove wall is in a second wall plane that extends outwardly away from the rotor axis in the direction of rotation and intersects the rotor axis. A plurality of first base support surfaces are each in a base support plane, perpendicular to the first wall plane and intersect each other. A plurality of second base support surfaces are each in a base support plane, perpendicular to the second wall plane and intersect each other. A rectangular flat cutter blade is clamped to each base support surface.
