The shower assembly includes a main body having a side wall, an end wall, a plurality of outlet bores and an inlet bore, wherein the side wall and end wall are connected to each other to compose an accommodating space. The outlet bores and the inlet bore are positioned on the side wall of the main body, and communicate with each other through the accommodating space. The control member is positioned in the accommodating space of the shower assembly, and has a flow channel and a plurality of through holes. Each of the through holes communicates with each other through the flow channel, and is corresponding to the inlet bore or one of the outlet bores. When the control member is operated, at least one of the through holes communicates with the inlet bore, and another one of the through holes communicates with the corresponding one of the outlet bores.

A liquid supply assembly is provided. The liquid supply assembly includes a receiving portion, a dispersing portion, and two flow controllers. The two flow controllers are connected between the receiving portion and the dispersing portion. A plurality of perforations are formed on the dispersing portion.

A shower includes a first shower assembly, a rotatable valve and a second shower assembly. The first shower assembly has a first inlet bore and a first outlet bore individually separated from each other. The rotatable valve has two diverter flow paths which are separated from each other, and has a second inlet bore and a second outlet bore, wherein the second inlet bore communicates with the second outlet bore. The second shower assembly has a third outlet bore communicating with the second outlet bore. The second shower assembly is connected to the rotatable valve. The second shower assembly is turnable relative to the first shower assembly to rotate the rotatable valve. When the second shower assembly is turned to rotate the rotatable valve, the first outlet bore, the second inlet bore or the both communicate with the first inlet bore through at least one of the diverter flow paths.

An annular discharge device for discharging a gluing composition onto glass fibres includes at least one distribution circuit for the gluing composition and a plurality of spray nozzles fluidically connected with the distribution circuit and distributed over the perimeter of the annular discharge device for discharging the gluing composition onto the glass fibres intended to pass into the annular discharge device defined by an axis of revolution, each spray nozzle being oriented towards the interior of the annular discharge device with an angle of inclination determined in relation to the plane of revolution of the annular discharge device. At least two spray nozzles arranged consecutively on the perimeter of the annular discharge device are disposed so as to have an orientation with respect to the plane of revolution of the annular discharge device each with a different angle of inclination with respect to one another.

A cartridge acting as a dispenser for liquid treatments of a human or animal body is U shaped or hoop shape. The cartridge has a container containing a liquid treatment which when required to be dispensed is ejected through one or more nozzles projecting through the wall of the cartridge into the centre of the U or of the hoop. A base is provided for cartridges, the base controlling timing and quantity of treatments.

A gas distribution system for a polysilicon deposition reactor eliminates or mitigates the problems associated with prior art distribution systems employs at least two segments which are gas-tightly connected to one another by readily detachable fasteners, with at least one gas inlet opening and one gas outlet opening, the gas distributor of the system being mounted by readily detachable fasteners to the polysilicon reactor.

A water sprinkler mat includes an annular water bag, a base mat and a water inlet mechanism, a radially inner sidewall of the water bag is configured with a plurality of water orifices; the base mat is fixedly connected to the inner sidewall of the water bag; the water inlet mechanism includes a first water inlet pipe and a water distributive pipe, the first water inlet pipe is inserted in the water bag and is fixed with the water bag; the water distributive pipe is located inside the water bag, the first water inlet pipe is configured with a first guide hole, the water distributive pipe extends through the first guide hole and is fixed with the first water inlet pipe; two ends of the water distributive pipe are open, a water inlet opening in communication with the first water inlet pipe is defined at the water distributive pipe.

A method for effective and efficient water or wastewater aerosolization and industry specific and regulatory agency approved ADC, soil stabilization or penetrating solution dissemination over identified and specific areas that are to be addressed. The water or wastewater and industry or regulatory body specifically approved ADC, soil stabilization or penetrating reagent solution(s) is directed to an Integrated Mobile Aerosolization System (IMAS) or other system having a turbine and being integrated and mobile. The turbine is driven so as to generate a system of air. Integrated pumps are utilized to move the water or wastewater and industry or regulatory body specific and ADC, soil stabilization or penetrating reagent solution(s) to a series of nozzles that aerosolizes the water or wastewater and ADC, soil stabilization or penetrating reagent solution into the path of the system of air. The water or wastewater and ADC, soil stabilization or penetrating reagent solution form a mixture that is entrained in the system of air. The mixture of water or wastewater and ADC, soil stabilizing or penetrating reagent solution is directed over a specific area that is to be covered with an approved material. The water or wastewater and ADC, soil stabilization or penetrating reagent solution form that industry specific and regulatory body approved covering material that is applied to the specific area.

A device and method for at least partial loosening of a connecting layer of a temporarily bonded substrate stack. The device has at least one ring, whereby the substrate stack can be placed within the at least one ring, the at least one ring having a plurality of nozzles. The nozzles are arranged distributed at least over a portion of the periphery of the at least one ring, the nozzles directed onto the connecting layer.
