A liquid dispenser filling hose for use in filling a liquid dispenser with liquid from a liquid reservoir via a pump, comprising: a distal coupler for coupling the filling hose to the liquid dispenser; and a controller arranged to control the pump. The liquid dispenser may be filled using a method comprising: providing a liquid reservoir, a pump and a controller arranged to control the pump, and a filling hose having a proximal end and a distal end, the proximal end of the filling hose being coupled to the liquid reservoir; coupling the distal end of the filling hose via a distal coupler to the liquid dispenser; and transferring liquid from the liquid reservoir via the filling hose to an airless liquid container forming part of the liquid dispenser. A system for filling a liquid dispenser, comprising: the liquid filling hose; and a liquid reservoir and/or liquid supply station is also described.

A coupling may be configured to receive and secure an insertion end of a conduit. An outer surface of the insertion end of the conduit may be smooth and free of grooves, flanges and beads. A first member of the coupling may define a first passageway. A second member of the coupling may define a second passageway. The first member may be in spin weld engagement with the second member. A gripping ring having an inner edge defining a series of teeth may be disposed within the second member. A support ring and O-ring may also be disposed within the second member.

A rotary introducer is provided for introducing a trackable element and/or contaminant onto a flow path of a food-transit system without adjusting a flowrate. The introducer comprises an inlet and an outlet which is communicable with a food-transit conduit; and a pair of rotatable driving/drivable members. In a trackable-element receiving condition, the inlet is open to receive a trackable element in the device cavity, and the outlet is closed by at least one of the driving/drivable member. However, in a discharge condition, the outlet is open such that a trackable-element discharge force is directed radially inwardly through the outlet to discharge the trackable element from the device cavity, thus enabling outlet to close. A food-transit system using the rotary introducer and a method of introducing a trackable element and/or contaminant into food-transit system without adjusting a flowrate of foodstuffs therethrough are also provided.

Wall feed-through element for a fluid line that includes a housing having a feed-through region running in an axial direction with at least one attachment geometry and a stop. The feed-through region is structured with a bearing section and the connection geometry, on a side of the bearing section facing away from the stop at least one, includes at least one shaping protruding radially over the bearing section with a back wall facing the stop and at least one radially springable projection that is offset in a circumferential direction with respect to the shaping and extends toward the stop in an axial direction and beyond the back wall.

A method for manufacturing a pipe is described, wherein the method comprises a step of fastening a second mechanical quick connection member to a rectilinear hollow tubular body, a step of positioning the rectilinear hollow tubular body in a bending machine so that the angular coding mechanism of the second mechanical quick connection member is in a reference angular position with respect to said bending machine, and a step of bending the rectilinear hollow tubular body as a function of said angular reference position.

A plumbing fitting assembly includes an anchor member for being received in a transverse hole in a structure. One end of the anchor member is externally threaded and the other includes a catch portion for engaging a surface of the structure adjacent the hole. The threaded end is threaded into a clamping member configured to form a seal with the opposite surface of the structure or another liquid conveying structure. The anchor member can include a tool formation for mating with a rotating structure of a tool. The assembly can include a lock ring for being lockingly received in an interior passage to prevent the catch portion from deflecting inwardly when installed. The plumbing fitting assembly can also be configured for forming a plumbing fitting at a transverse hole in a flexible, liquid-impermeable panel.

A coupling that includes a female coupling member having at least one electrically conductive ring on an inner mating surface; a male coupling member having at least one electrically conductive ring on an outer mating surface, the outer mating surface sized to fit within the inner mating surface of the female coupling member; and wherein when the male coupling member is inserted into the female coupling member, alignment of the at least one electrically conductive ring of the female coupling member with the at least one electrically conductive ring of the male coupling member indicates whether the female coupling member and the male coupling member are fully engaged.

A portable frame is configured to be transported by the forks of a fork lift truck and has hydraulic lines releasably connectable to the auxiliary hydraulic fluid pressure system of the fork lift truck. A valve and a set of hydraulic lines are mounted on the portable frame for releasable connection to the hydraulic fluid lines of a tillage machine so that an inexpensive fork lift truck may be utilized to test operation of hydraulically actuated tillage components.
