A high pressure surface cleaner includes a housing having an open end, a high pressure coupling in fluid communication with the housing and having a first end and a second end, the first end configured to receive a high pressure water source, and a supply conduit rotatably secured to the second end of the high pressure coupling and configured to rotate about the high pressure coupling defining a horizontal plane within the housing. The cleaner also includes first and second nozzles having a vertical axis therethrough and secured proximate to the first and opposing second ends of the supply conduit, respectively, the vertical axis of the first and second nozzles approximately normal to the first horizontal plane, and a directional nozzle coupled to the supply conduit and having a directional outlet orientated to cause the supply conduit with the first and second nozzles to rotate when discharging water.

Present invention enables to mass-produce rich-taste tamari soy sauce with reasonable costs. First step: Moisturizing soybeans. Second step: Steaming the moisturized soybeans. Third step: Shaping the steamed soybeans into nuggets. Fourth step: Mixing a soy flour and seed koji. Fifth step: Putting the mixture on the nuggets. Sixth step: Incubating the nuggets. Seventh step: Putting the incubated nuggets in salt water. Eighth step: Fermenting the nuggets in the salt water. Ninth step: Pressing moromi (solid component of the fermented product). Tenth step: Settling the liquid obtained by pressing the moromoi. Eleventh step: Optionally filtrating raw tamari soy sauce with a reverse osmosis membrane. Twelfth step: Adjusting concentrations of some constituents of the raw tamari soy sauce. Thirteenth step: Pasteurizing the raw tamari soy sauce. Fourteenth step: Settling the pasteurized tamari soy sauce. Fifteenth step: Filtering the supernatant. Sixteenth step: Bottling the tamari soy sauce.

A pulsating device has a chamber for receiving liquid entering the device and gas that occupies an initial volume in the chamber. The liquid entering the chamber compresses the gas and decreases the volume occupied by the gas, thereby increasing the pressure in the chamber. A valve is provided to open above a first threshold pressure to begin a pulse of liquid. The valve closes below a second threshold pressure to end the pulse. The pulsating device has an outlet gate that permits liquid in the chamber to exit the chamber when the pressure in the chamber is greater than the pressure outside the chamber.

Rotational speed of a spray arm is regulated based on centrifugal force and a liquid jet to create a variable angle corner spray nozzle. The regulator includes a weight on a pivot and a fluid jet, the weight having a curved surface to produce a variable angle corner spray nozzle depending on the weight angle. Centrifugal force created during rotation pushes the weight outward, which increases as the spray arm rotation speed increases. The liquid jet is located out from a pivot point and tends to push the weight inward. The pushing force of the liquid jet is maximum when the weight is most inward and minimum when the weight is most outward. The regulator stabilizes the arm speed at a specific speed independent from center pivot friction and the spray arm nozzle's orientation tolerance. Speed stabilizes when centrifugal force on the weight is equal to the pushing force of the fluid jet.

A pneumatic cleaning gun according to the present invention comprises a gun housing with a compressed air connection, a liquid nozzle with a nozzle cover, and an air intake tube which leads into the covered flow channel and can also be connected to a suction device via a suction hose in order to suction dirt particles through the flow channel. The cleaning gun is configured such that the air intake tube is not rigidly but pivotably mounted on the cleaning gun. The air intake tube can therefore be mounted in a plurality of different positions of use such that the user can find the most comfortable or convenient position of use and the air intake tube can be correspondingly adjusted.
