Abstract: A dispenser for dispensing viscous and non-viscous materials includes a frame, a material storage positioned within the frame and containing at least one material to be dispensed, and a dispensing mechanism for acting on a piston for dispensing the material from the material storage. The dispensing mechanism includes a driving unit to generate driving energy for causing the dispensing movement of the piston, and an energy buffer to absorb a portion of the energy generated by the driving unit during the dispensing movement of the piston. The energy buffer outputs the absorbed energy over a longer period of time than the driving unit is operated to move the piston.

Abstract: A dispenser dispensing a component of material includes a cartridge to store the material to be dispensed, a dispensing mechanism to urge the material towards an outlet of the cartridge, a trigger configured to activate the dispensing mechanism, and a connection device at a dispensing end of the dispenser to connect the dispenser to a spray applicator, with the spray applicator spraying the material out of the cartridge.

Abstract: A dispenser for dispensing materials includes a dispenser body, a driving rod movable relative to the dispenser body and into the receptacle, a trigger lever having an actuation member for displacing the driving rod upon rotation of the trigger lever around a rotation axis, and a pivot member that rotatably connects the trigger lever to the dispenser body and defines the rotation axis. The pivot member is movably connected to the trigger lever such that a lever distance between the rotation axis and the actuation member changes upon movement of the pivot member relative to the trigger lever. The dispenser includes an adjustment mechanism for adjusting a mechanical advantage of the trigger lever by changing the lever distance and to adjustably fix the lever distance to at least a minimum distance and a maximum distance.

Abstract: A dispenser for spray applications includes a receptacle for repeatedly receiving a cartridge, a plunger moveable for dispensing, and a spray nozzle for activating a spray application and a trigger.

Abstract: A method and apparatus for automatically sensing the configuration of a damaged surface area and wherein the apparatus is provided with an arc gouging tool, a welding tool, and a grinding tool to gouge damaged areas and fill them with weld material to at least the surface profile of the surface in the working environment and to grind the filled areas flush with the surface of the working environment. A track is bent to a profile enabling the apparatus to work without any collision with its environment while keeping full access to the work area. The geometry of the track is generally unknown to the control circuit of the robot. A motor-actuated robot member is connected to the track and is displaceable on the track by a motorized element. A working arm is displaceably coupled to the robot member and has one or more working tools connected thereto. A control circuit displaces the robot and operates the working arm and tool.
