Abstract: An improved vaporizer part, such as an evaporator element of a disinfection device is for an aqueous solution of hydrogen peroxide. The evaporator element includes one, and/or a branching, meandering structure, in which the straight sections of the groove are joined by 180-degree meanders near edges of the evaporator element. An end pit with an overflow guard is for overflown liquid. Heating elements are used both in connection with the evaporator element to enhance evaporation and on the inner surfaces of the device to prevent condensation. An air blower creates desired vortices near the surface of the evaporator element. The air control element also makes the air flow more laminar. The actual travel of the liquid on the evaporator element functions gravitationally on an inclined surface, and the capillary effect increases the evaporating area of the liquid. A disinfection device includes the vaporizer part.

Abstract: In a manufacturing method of a laminate structure according to the invention, a manufacturing apparatus of the laminate structure is used, which apparatus comprises material containers for the glue paste components, a separate pump for each glue paste component, which pumps are arranged to pump the components of the glue paste to be manufactured through the outlet pipes to the mixing unit.

Abstract: In the manufacturing method and manufacturing arrangement according to the invention for a silicone composition the mixer mixing the different subcomponents of the silicone composition are removed for the duration of downtime and cooled to a temperature, in which the chemical reaction between the different subcomponents of the silicone composition stops. In the manufacturing method of the invention the mixer is reconnected to the manufacturing apparatus arrangement after downtime without cleaning it from the silicone composition subcomponents remaining in the mixer.

Abstract: Discharge device for discharging a container containing viscous substances and having an elastic shell material, has a winding roller, a counter pressure roller, an actuator for rotating the winding roller and a control part for controlling the actuator. The inner part of the winding roller is hollow and includes therein an attaching arrangement, where the shell material of the container to be discharged is attached. The shell of the winding roller has an opening, in which opening there is a lid part having a shape for the shell material of the container attached to the attaching arrangement. The winding roller is rotated so that the shell material of the container attached to the attaching arrangement is wound around the winding roller. The winding roller and counter pressure roller are pressed against each other so that the shell material of the container winding around the winding roller passes between the rollers.

Abstract: A pumping method and arrangement, in which at least two chamber pumps (A, B) are operated in order to achieve a constant output flow. In the pumping procedure and arrangement, the entry chamber (110, 130) of the chamber pump is pre-pressurised close to the actual working pressure after the filling stage in order to achieve a constant output flow.
