The invention provides a carbonation tank assembly for admixing a gas and a potable liquid used in preparation of drinks. The assembly includes a tank body with an interior that can be easily accessed for cleaning and repair purposes by removing upper and lower end plates securely and sealing fitted by gaskets to the upper and lower ends of the tank. The interior is connected to a liquid source for supplying liquid, a gas source for carbonating the liquid, and drawing means for dispensing carbonated liquid from the interior of the tank.

An application dispenser for at least one component, in particular for an adjustable dosing and/or mixing dispenser, includes a rotation element, in particular a ball for applying the at least one component, and a pump configured to load the at least one component with pressure and feed the at least one component under pressure onto the rotation element.

A dilution control device and method of operating the same. The dilution control device can include a structure for dispensing concentrate and diluent fluid in a desired dilution ratio utilizing volumetric dosing. In some embodiments, diluent fluid drives a wheel or compresses a pliable concentrate bag in order to dispense concentrate in the desired ratio with the diluent fluid. In some embodiments, one or more floats can be used to drive a pump or actuate a valve to dispense concentrate at a particular rate proportional with the flow rate of the diluent fluid. In some embodiments, a rocker is responsive to the flow of diluent fluid to pump concentrate. In some embodiments, the dilution control device can be operable to automatically modulate the dispense rate of concentrate when the diluent fluid flow rate is varied in order to maintain a predetermined dilution ratio.

In an apparatus for feeding animals including one or more feed dispensing containers from which the animals can take feed which are fed by supply ducts from a supply a device is provided which includes a feed supply duct portion arranged such that the feed falls through the feed supply duct portion under gravity. A drive member is mounted at the duct and includes a plurality of paddle blades of a wheel mounted for rotation about an axis of the wheel such that falling feed in the duct acts to drive the blades to rotate the wheel about the axis and a driven component driven by the wheel. The driven component is in most cases a dispenser for feeding a liquid or particulate additive material from a supply cartridge, which is mounted on a common housing forming the duct and containing the wheel, to an injection opening on the bottom of the housing for addition to the feed passing through the duct portion.

A device and method for chemicals to be fed into a water system, treating the water system as it enters, for example, a fire protection mains and/or fire protection systems (FPS) to protect and maintain the longevity of the water system preventing damages to the water system or enhancing the operation characteristics of the system. This device is a treatment system that may be installed as a portable or permanent device with chemicals such as, corrosion inhibitors, wetting agents, polymeric dispersants, biocides, biostats or other water chemical enhancing effects with means for injecting the chemicals into the fire protection system or a bypass feed system utilizing the fluid means without the need for any electricity. Activation of the pump occurs when water enters the FPS mains and FPS sprinkler system from an outside source. Valving is included to isolate the pump and drums, storage tank to prevent backflow from the FPS.

Some embodiments provide a recirculating aquaculture system for aquatic life. The system includes a culture tank, a sensor configured to measure a carbon dioxide concentration in the culture tank, a variable speed pump configured to circulate water through the culture tank, and a controller in communication with the sensor and the variable speed pump. The controller is configured to retrieve a maximum carbon dioxide concentration in the culture tank, retrieve a current carbon dioxide concentration, and compare the current carbon dioxide concentration to the maximum carbon dioxide concentration. When the current carbon dioxide concentration is greater than the maximum carbon dioxide concentration, the controller is configured to automatically increase the current water flow rate or automatically increase the current air flow rate based on the current gas to liquid ratio in the system.

Disclosed is a method and system for blending a foam modifier with foaming agent online, e.g., as may be particularly useful for gypsum or cement slurries. The foam modifier comprises a fatty alcohol that is added to a gypsum or cement slurry that includes foaming agent, such as an alkyl sulfate surfactant. The fatty alcohol can be a C.sub.6-C.sub.16 fatty alcohol in some embodiments. The use of such a foam modifier can be used, for example, to stabilize the foam, reduce waste of foaming agent, improve void size control in the final product, and improve the gypsum board manufacturing process.

An adding system for fire-extinguishing units includes a motor, which can be driven by an extinguishing agent stream, an adding pump, which can be driven by the motor, an adding line, and an extinguishing agent additive line. The outer wall of the working chamber of the motor is in the form of a rotation motor, which can also have the shape of a logarithmic spiral. Furthermore, the wall of the drainage housing of the motor, which is in the form of a rotation motor, can have a through-slot for letting the extinguishing agent in and/or out. Moreover, the inlet of the adding pump can be arranged such that the extinguishing agent additive can flow into the adding pump substantially parallel to the movement direction of the pistons of the adding pump. Finally, the adding pump can have an integrated relief valve.
