Abstract: Draining of the waste tank of a recreational vehicle is improved by using a motor to operate the waste hose. The motor causes the proximal end of the hose to be extended from its housing in the RV while the distal end remains attached to the waste tan. The extended proximal end can then be inserted into the access pipe of a sewer system for draining the waste tank. The motor will retract the hose when the waste tank has been emptied. The motor is operable either by throwing a switch on the motor or pressing a button on a remote control unit.

Abstract: A cylinder containing gas has a valve and is connected to a delivery side through a filling pipe, a primary pipe, a first air-operated valve, a pressure reducing valve, a secondary pipe, and a second air-operated valve. Inert gas flows into the primary pipe through an air-operated valve. The primary pipe is connected to a vacuum generator through an air-operated valve and a pipe. Gas remaining in the primary pipe is purged as exhaust gas by automatically repeating leaving-pipe-in-pressurized-state purge for pressurizing the inside of the primary pipe by the inert gas and leaving the pipe in this state for 2 to 10 minutes and evacuating the pipe for 20 seconds. Gas remaining in the primary pipe is purged with high-efficiency, and the vacuum generator is stopped while the inside of the primary pipe is pressurized in the leaving-pipe-in-pressurized-state purge and the just-before-replacement purge.

Abstract: A depression container comprises a vessel including a compartment and a cover for enclosing and thus sealing the compartment. An air pump draws air out of the compartment and a pressure-activated switch controls on/off of the air pump. The pressure-activated switch detects an internal pressure in the compartment. The air pump is turned on when the internal pressure is higher than a predetermined first pressure value.

In an alternative embodiment, the pressure-activated switch detects a pressure difference resulting from a closing motion of the cover on the vessel and turns the air pump on to thereby draw air out of the compartment of the vessel. The air pump is turned off when an internal pressure in the compartment detected by the pressure-activated switch is lower than a predetermined pressure value.

Abstract: A fuel tank having an inlet and an outlet is connected to a separate pressure vessel by means of a pump. Fuel vapors are pumped out of the tank and into the pressure vessel while the tank is being filled via the inlet, so that fuel vapors cannot escape during filling. After filling, the inlet is closed and the pressure in the tank is increased to about 4 bar by means of a pressure regulator in a line connecting the pressure vessel to the fuel tank. The pump is then switched off and the fuel can be delivered to the engine via the outlet under the increased fuel pressure in the tank, the pressure being reduced to fuel system pressure by a pressure regulator in the outlet line.

Abstract: An apparatus and a method for dispersing and feeding dry powders without using pressurized air are disclosed. The apparatus comprises a sample holder, a suction probe, a vacuum means and a positional means. The suction probe is positioned above dry powders in the sample holder, a space between the suction probe and the sample holder is substantially small that allows non-pressurized ambient air to form an high velocity downward air flow when a vacuum is applied to the suction probe. A change of air flow direction at an orifice of the suction probe generates a high shear force above the dry powders, which disperses the dry powders into an airstream. The apparatus feeds the dry powder airstream to a particle analyzer with a controlled rate. The apparatus and method are particularly useful in sizing particles using laser diffraction or image analysis techniques.
