Abstract: A hand held dispenser for dispensing foamable compositions is disclosed that is particularly useful for foam-in-place packaging systems. The hand held dispenser comprises a housing; a motor in the housing; a transmission in the housing and driven by the motor; and a valving cartridge in the housing and driven by the transmission for dispensing foamable compositions upon demand. The motor is positioned below the valving cartridge for providing a clear line of sight along the top of the housing.

Abstract: Long reinforcement fibres are incorporated into a plastic part made of a chemically reactive plastic mixture or molten thermoplastic materials. For the long reinforcement fibres to be gently and homogeneously distributed in a single operation in the fluid plastic materials without being destroyed, before the fluid plastic materials are pressed in a plastics moulding tool, a flow of fluid plastics is generated and joined to a flow of long reinforcement fibres outside a mixing chamber where the reactive plastic mixture is prepared or outside a melting unit where thermoplastic materials are molten.

Abstract: A two-component thermosetting polymer system is formed and dispensed by adding a foaming agent to one of two components of the polymer system. A solution of the foaming agent in the first component is formed in a supply tank. The foaming agent and first component solution is then mixed with a second component at a dispensing head or nozzle. By adding the foaming agent to only one of the two components and, in particular, by forming a solution of the foaming agent in the first component one is able to very carefully control the foam density of the cured end product.

Abstract: A process and a high-pressure mixing apparatus for the production of a frothed polyurethane foam. Two reactive chemical components and a low-boiling blowing agent (CO2) are mixed into a high pressure mixing apparatus comprising a mixing chamber (10) connected to a discharge duct (19); the flow of the mixture is throttled to generate a pressure inside the mixing chamber (10) which is sufficient to maintain the blowing agent at a liquid state. The mixture is thereupon frothed by releasing the blowing agent along a frothing chamber (18) extending between the mixing chamber (10) and the discharge duct (19); a back-pressure is generated into the frothing mixture by extending the frothing chamber (18) for a substantial length and by changing the flow direction of the frothing mixture while flowing from the frothing chamber (18) into the discharge duct (19).

Abstract: A device for mixing at least two reactive components consists of a cylindrical mixing chamber into which the plastic components are injected and in which there is a reversible piston, and a cylindrical stabilising chamber adjoining the mixing chamber preferably at an angle of 90 DEG and having a reversible cleaning piston to extract the reactive plastic mixture from the stabilising chamber. In order to reduce the forces exerted on the cleaning piston by the plastic mixture and to reduce the tear-off forces on a stuck piston to the minimum it is proposed that there be recesses on the cylindrical jacket surface of the cleaning piston which are filled with spacer material and arranged on the principle that the cleaning piston performs a rotary movement at the same time as its axial stroke.

Abstract: The invention relates to a mixing head for the counter-current injection mixing of fluids, with a mixing chamber into which the fluids to be mixed are injected towards one another through opposite mixing nozzles. Said mixing head is characterized in that there are at least two premixing chambers (2, 3), the outlets (8, 9) of which open into a mixing chamber (10) and are, in particular, arranged opposite each other there so that the fluid mixtures obtained in the premixing stage are once again injected towards each other and remixed. This mixing head is suitable in particular for mixing the various fluid initial components of reactive polyurethane systems.
