Abstract:
An electrolyzing system for electrolyzing a brine solution of water and an alkali salt to produce acidic electrolyzed water and alkaline electrolyzed water is provided. The system includes an internal chamber for receiving the brine solution and two electrolyzer cells immersed in a brine bath. Each electrolyzer cell includes an electrode, at least one ion permeable membrane supported relative to the electrode to define a space communicating between a fresh water supply and a chemical outlet into which brine enters only through the membrane. One of the electrodes is coupled to a positive charging electrical supply and the other to a negative charging electrical supply.
Abstract:
A shower header type spraying device having an elongated spray header with a plurality of laterally-spaced nozzles and an elongated cleaning brush assembly supported in said spray header for cleaning inlet apertures of said spray nozzles. The cleaning brush assembly includes an axially extending rod and a plurality of brush elements each mounted on the rod by means of a self-aligning member that has an arcuate shape corresponding to the outer circumference of the rod for orienting a row of brush bristles of the brush element in predetermined relation to the elongated axis of the rod. The illustrated brush rod assembly includes a plurality of brush rod segments each having a self-aligning coupling at an axial end thereof such that joining of adjacent rod segments automatically orients the brush elements in predetermined angular offset relation to each other.
Abstract:
A lubricant dispensing system is provided. The dispensing system includes a lubricant supply, a lubricant dispensing nozzle and a control panel. The dispensing nozzle includes a nozzle body with a fluid passageway therein which is in fluid communication with the lubricant supply, an electrode assembly for electrostatically charging lubricant in the fluid passageway and at least one discharge orifice through which electrostatically charged lubricant can be discharged. The discharge orifice is defined by at least one spray needle having a first end in fluid communication with the fluid passageway and a second end that extends outward of the nozzle body. The control panel directs the flow of lubricant from the lubricant supply to the lubricant dispensing nozzle and controls the electric power supplied to the electrode assembly.
Abstract:
A liquid adhesive dispensing system operable for more uniformly applying liquid adhesive foam onto moving substrates, notwithstanding changes in line speed, adhesive liquid flow rates, or foaming/atomizing air pressures. The illustrated liquid adhesive system includes a header having a plurality of air atomizing spray guns; the spray guns each having a respective variable speed positive displacement pump for directing a metered quantity of liquid adhesive from a liquid adhesive supply to the respective spray gun; and a control for controlling the operating speed of the positive displacement pumps in relation to the speed of the moving substrate and the foaming/atomizing air pressure to the spray guns in relation to the operating speed of the positive displacement pumps. The control further is operable for monitoring pressures across the positive displacement pumps for insuring the accurate direction of metered quantities of liquid to the spray guns. The spray guns are adapted for enhanced liquid adhesive foaming and atomization, and the header is convertible into a closed housing structure effective for containing cleaning and purge liquids during an automatically operable cleaning cycle of operation.
Abstract:
An apparatus and method for processing elongated sheet material through a plurality of processing stations including a cooling station for lowering the temperature of the sheet material. The cooling station includes a plurality of individually controllable cooling zones each for controlling a portion of the transverse width of the sheet material during passage through the cooling zone. The cooling zones each include a plurality of cooling fluid directing spray nozzles and a sensor for sensing the temperature of the portion of the sheet material onto which cooling fluid has been directed by the respective cooling zone. A controller responsive to the temperature sensed at each cooling zone is operable for independently controlling the flow of cooling fluid to the fluid spray nozzles of each cooling zone based upon a preset temperature setting of the controller.
Abstract:
A spray nozzle assembly comprising a nozzle body and a separate nozzle body insert adapted for removable snap action engagement with the body. The nozzle body insert defines a liquid flow passage that includes an inlet section for communicating with a liquid inlet, a metering orifice for accelerating the liquid flow stream, and a downstream expansion section. The body insert further includes a venturi passage communicating with the expansion section for drawing ambient air into the liquid flow stream for stabilizing the liquid prior to discharge from the nozzle. In the illustrated embodiment, the expansion chamber communicates with a transverse passage of the nozzle body, which in turn communicates with a laterally oriented discharge orifice.
Abstract:
A full cone liquid spray nozzle is provided. The spray nozzle includes a nozzle body having a discharge orifice at a downstream end and an inlet at an upstream end for connection to a liquid supply. A liquid flow passageway extends through the nozzle body communicating between the inlet and the discharge orifice. A vane is disposed in the liquid flow passageway upstream of the discharge orifice. The vane has a plurality of V-shaped passageways therein. Each V-shaped passageway extends inward at an angle with respect to a longitudinal axis of the vane between an upstream face and downstream face of the vane. A whirl and mixing chamber defined by the liquid flow passageway is arranged between the vane and the discharge orifice.
Abstract:
A liquid dispensing device for dispensing predetermined small quantities of liquid during each operating cycle. The dispensing device includes a body having a main liquid passage section that defines a liquid dispensing chamber with a liquid inlet port communicating through a side wall of the passage section and a stop surface at a downstream end of the passage section. A liquid dispensing stem having an annular sealing member about the stem is mounted for movement between retracted and liquid dispensing positions for dispensing a controlled small quantity of liquid, such as 0.10 mm or less, determined by the size of the liquid dispensing chamber less the displacement volume of the stem downstream of the sealing member.
