Abstract:
In the reciprocating pump P, the pressure chamber 30 is formed by an atomizing tube 15, a piston 28, and a cylinder 20. The pressure chamber 30 has a check valve 24 that opens and closes the inlet of the said pressure chamber 30 and a ball-shaped stirring material 25 moving freely in the pressure chamber 30 that stirs the mixture in the pressure chamber 30. On the other hand, pumping space is formed by the piston 28 and the cylinder 20 in the reciprocating pump P, apart from the pressure chamber 30. The pumping space 29 is occupied by the mixture pumped up when the push button 17 is returned to its home position and communicating holes are provided through which the mixture is discharged into the container 10 when the push button is pressed. The atomizer of an reciprocating pump type of the present invention can stir sufficiently and atomize a liquid-powder mixture when used.
Abstract:
An extrusion device includes a container, a pump, a plurality of pipes, and an adjustment device. The container has a chamber, and a first inlet/outlet and a second inlet/outlet connected to the chamber, wherein the chamber is adapted to contain a fluid inside. The pipes are connected between the pump and the first and second inlet/outlets of the container, so as to form a fluid loop. The pump is adapted to drive the fluid to flow inside the fluid loop. The adjustment device is coupled to the container for adjusting a volume of the chamber. Further, a coating system is also provided.
Abstract:
The water purification filter is coupled intermediate any conventional shower head feed pipe and shower head. The filtration device is toroidal with a serpentine flow path. The filtration device envelopes the feed pipe which enables the shower head to remain within substantially the same location as before the insertion of the filter. To purify the shower water, the filter contains a filter media coupled between two filter screens.
Abstract:
Provided is a coating system allowing on-demand preparation and coating of an ink. The coating system (10) includes an ingredient ink supply portion (20), a first pipe (90a), a stirring tank (50) including an ink stirring mechanism (52), a supply regulator portion (30) regulating the respective amounts of ingredient inks supplied to the stirring tank, a controller portion (70) connected to the supply regulator portion through an electric telecommunication line (80), determining a mixing ratio of the ingredient inks, and controlling operation of the supply regulator portion based on the mixing ratio, and a coating device (100) including an ink transport portion (120) connected to the stirring tank and including an ink discharge portion (130).
Abstract:
A hand-held compressed air duster apparatus comprises a pressurizable vessel for containing a fine particulate dusting material. The vessel has an upper shoulder provided with a sealable top opening, in which a hand pump is mounted and sealably connected to the top opening. The pump comprises an external handle connected to a piston extending into the vessel. A dust discharge outlet is disposed on the shoulder of the vessel. Located within the vessel are two concentric tubes. A rotatable outer tube having a closed lower end that is provided with a pivot foot in contact with the bottom of the vessel extends upwards to an open upper end that is in fluid communication with the interior of the vessel. The rotatable outer tube comprises a dust feed agitator pin extending outwardly from the outer surface of the tube. The rotatable outer tube further comprises a venturi disposed above and in close proximity to the dust feed agitator pin and an agitator weight mounted on the outer surface of the tube above the venturi. An inner tube has an open lower end and an upper end that is connected to the dust discharge outlet. Operating the handle actuates the pump to pressurize the vessel, which is manually rotated to impart motion to the agitator weight and dust feed agitator pin attached to the rotatable outer tube, thereby maintaining the venturi open to entry of fluidizable dust particles proximate the open venturi and providing a mechanism for discharging uniformly fluidized dust at a controlled rate from the discharge outlet.
Abstract:
A backpack spray apparatus for applying insecticides and fertilizers comprises a large tank in which is mounted a pressure vessel. A pumping assembly is connected with the bottom portion of the pressure vessel and also with the bottom portion of the container tank. It consists of a double-acting piston assembly, a valve, and passages to connect a portion of the cylinder chamber above the piston assembly to the pressure vessel and to the container tank, so that upon reciprocation of the piston there is pumping of liquid from the container tank to the pressure vessel. There is also a connection between the portion of the cylinder chamber below the piston assembly and the lower portion of the container tank, so that upon reciprocation of the piston assembly there is pumping of the liquid back and forth. An operator-actuated handle reciprocates the piston assembly. There is no diaphragm associated with the pumping assembly--all pumping being done by the pumping assembly. Any liquid that leaks from the piston assembly does not drop onto the operator or the earth but instead joins liquid being pumped back and forth as above indicated.
