Assembly for dispensing a liquid, in particular a colorant for paint, comprising a container for holding a liquid, a pump, a valve, at least one dispense opening, and comprising or associated with a controller arranged to operate the pump and the valve to withdraw liquid from the container and to dispense liquid via the opening and to operate the pump and the valve to purge liquid from the pump to the container via the dispense opening.

A technique facilitates various types of cementing applications, such as a downhole cementing applications along a wellbore. The technique utilizes a mixer having a rigid body and a flexible skirt disposed along at least a portion of the interior of the rigid body. The mixer further comprises a cement blend inlet and a fluid inlet through which cement blend and fluid are introduced into the mixer to form a cement slurry. The flexible skirt is constructed to enable selective deformation, e.g. flexing, during formation of the cement slurry to reduce or prevent the formation of cement slurry caking within the mixer.

A material handling system is described. The material handling system comprises a rigid frame and a moveable liner. The frame includes at least one aperture having an area and wherein the system comprises an actuator system for applying a force to a surface of the liner in the area of the aperture.

A mixing installation is provided for mixing a first agent to a liquid. The mixing installation includes a dosing assembly and a first agent supply conduit. The dosing assembly includes a venturi arrangement and a first dosing device between the first agent supply conduit and the venturi arrangement. The first dosing device includes a first agent passage and a first dosing mandrel having a first dosing pin that extends in the first agent passage, wherein the first dosing mandrel is axially slidable in its axial direction with respect to the first main body over a first release stroke by pulling between a dosing position in which the first dosing pin extends inside the first agent passage to define a first ring shaped dosing channel around the first dosing pin, and a retracted position in which the first ring shaped dosing channel is cancelled.

The invention relates to improvements in the technical field of feeding solid materials to mixing devices. For this purpose, the solid-material feeding device, inter alia, is proposed. The solid-material feeding device comprises the slide, which can be moved between a first end position and a second end position through a conveying connection, which is arranged between a funnel and a solid-material outlet of the solid-material feeding device. By means of the slide, adhesions within the conveying connection can be loosened without having to remove the conveying connection.

A mixing device and method for generating reaction plastic, the mixing device including: a mixing chamber configured to mix reactive components to generate the reaction plastic; a discharge unit, including a discharge pipe connected to the mixing chamber configured to discharge the reaction plastic generated in the mixing chamber; a cleaning piston that is axially aligned with the discharge pipe of the discharge unit and is moveable into the discharge pipe to clean reaction plastic from the discharge pipe; a fluid supply device configured to provide a lubricant into the discharge unit via an outlet to lubricate the discharge unit, a control piston arranged within the mixing chamber and configured to control flow of the reactive components; wherein an axial direction of the control piston is oblique to an axial direction of a discharge pipe of the discharge unit.
