A dispenser for applying at least two compositions, the dispenser including at least two reservoirs for storing the at least two compositions, at least two pumps for pumping the at least two compositions, a premix chamber containing a mixing element for mixing the two compositions, at least two channels for delivering the compositions from the reservoirs to the premix chamber, an exit orifice, optionally a swirl chamber, and an actuator.

A flow-control faucet aerator is configured to be fitted on a spout of a faucet and includes a housing, an aerating device installed in the housing, and a washer installed above the aerating device. The washer is provided with at least one mouth and an aqueduct circling the mouth. The aqueduct is made of an elastic material and has a neck that has a wall thickness smaller than a wall thickness of the rest of the aqueduct. The neck of the aqueduct deforms at different levels according to different levels of water pressure at the spout of the faucet, so as to change a diameter of the aqueduct and in a flow of the faucet, thereby contributing to flow control and water conservation.

A fluid flow emitter is provided, which is to be mounted within a fluid distribution tube to control the rate at which fluid is distributed from the tube. The emitter may include a cylindrical body having a pair of raised radially-extending annular portions extending circumferentially around the emitter. These raised portions define a fluid flow path. The body may define a multiplicity of apertures making up an aperture region disposed between the radially-extending annular portions. A flow control section is also provided which includes an upstream end and a downstream end. A fluid distribution region is also provided, into which the flow control section discharges. The fluid distribution region is in fluid interconnection with at least one orifice defined in the fluid distribution tube.

A method, a wiping apparatus, and a wiping system to store web material in a multi-folded state in a web storage chamber.

Control method and apparatus for a manual spray gun includes display that is disposed on the spray gun and that provides information to an operator about one or more coating operation parameters. An auxiliary trigger may be used that enables an operator to makes selections of one or more coating operation parameters. The display and auxiliary trigger together permit an operator to make selections without having to divert attention or field of view away from the spray gun or the coating area, especially during a coating operation.

An apparatus and associated methods for an automated pipe doping apparatus. The apparatus may include a pump fluidly coupled to a reservoir and a dope manifold, the pump positioned to pump pipe dope from the reservoir to the dope manifold; an ejector coupled to the dope manifold, the ejector positioned to supply a fixed volume of pipe dope from the dope manifold to a dope distribution line; and a pipe dope applicator, the pipe dope applicator fluidly coupled to the dope distribution line positioned to deposit pipe dope on a threaded connection. In some embodiments, the pipe dope applicator may be a fan-pattern nozzle. In other embodiments, the pipe dope applicator may be a mold-type applicator. In other embodiments, the pipe dope applicator may be a brush-type applicator.

A changer device for coating media having a housing, which has a delivery port which can be connected to an application device. At least one change unit is provided which includes at least a first and second inlet port, at least one outlet port and a valve device which may connect the first inlet port or the second inlet port to the outlet port, or which may block the flow channel to the outlet port. The valve device may be a rotating element and/or sliding element that is arranged in a valve chamber and includes a plurality of passage ducts which are able to connect fluidically the outlet port with one or both of the at least two inlet ports of the changer unit. The at least one such change unit may be provided in a coating system for coating objects with an application device and a plurality of reservoirs.

A paint sprayer includes an end bell, a motor connected to the end bell, a pump drive connected to the end bell, a pair of protrusions attached to an extending from the end bell such that each protrusion is cantilevered from the end bell, and a pump assembly comprising a pair of mounting holes and containing a piston. The pair of mounting holes is adapted to receive and slide onto the pair of protrusions to mount the pump assembly on the end bell as well as slide off of the pair of protrusions to remove the pump assembly from the end bell. The pump drive is configured to covert rotational motion output by the motor to reciprocal motion. The pump assembly is configured to pump paint when reciprocated by the pump drive while mounted on the end bell.

A device includes a rotary portion, which is mounted so as to rotate on a support structure around a rotation axis (X-X) between an angularly moved away condition and an angularly moved close condition relative to an outlet mouth. A shutter portion pivots relative to the rotary portion around a pivoting axis (Y-Y) lying on a plane that is transverse relative to the rotation axis (X-X). An actuating apparatus moves the rotary portion between the moved away condition and the moved close condition. The shutter portion is suited to pivot around the pivoting axis (Y-Y) from an open position, in which the shutter portion is spaced apart from the outlet mouth, to a closed position, in which the shutter portion lies against the outlet mouth, when the rotary portion shifts from the moved away condition to the moved close condition.

A system for coating a non-rotating pipe work piece including: valves, flow lines, and a mixing block for receiving a first and a second component material each delivered at a pressure, flow measurement devices to measure the flows of the components, a static mixer in fluid communication with the mixing block for receiving the combined components, a C-shaped plate member arranged around the work piece, a drive mechanism to oscillate a partial rotation of the C-shaped member about the work piece with the rate of oscillations controlled by a logic controller, at least two spray guns disposed on the C-shaped member to spray towards the outside surface of the work piece, a drive mechanism to traverse the at least two spray guns longitudinally with the rate of traverse controlled by a logic controller; and the logic controller(s) programmed to control based on a number of input and measured parameters.
