Abstract: The static mixer comprising mixing elements for separating the material to be mixed into a plurality of streams and means for the layered junction of the same, a transversal edge and guide walls that extend at an angle to said transversal edge, as well as deflecting elements arranged at an angle to the longitudinal axis and provided with openings, includes mixing elements comprising a transversal edge and a following transversal guide wall and at least two guide walls with lateral end sections and at least one bottom section disposed between said guide walls, thereby defining at least one opening on one side of said transversal edge and at least two openings on the other side of said transversal edge. In addition to a high mixing efficiency and a low pressure drop, a mixer of this kind provides reduced dead volumes and is thus more effective than mixers of the prior art.

Abstract: A metering device includes an inlet and outlet for a material (liquids, gases or solid particles) to be metered, a rotatable ball driven by a shaft and interposed between the inlet and outlet seats. The rotatable ball has a transverse bore containing a sealess shuttling member which can reciprocate back and forth along the bore between two sealing seats so as to seal against one or the other. The sealess shuttling member is propelled by pressurized material which flows into the bore without surface-to-surface contact of the shuttling member with the bore wall until is engages one of the two sealing seats. Each time the rotatable ball rotates 180.degree., a metered shot is ejected resulting in a quasi continuous flow depending upon a rotatable ball revolution rate.

Abstract: The bayonet attachment on the cartridge for attaching a mixer or accessory to a multiple component cartridge is formed as a ring-shaped bayonet socket with two internal recesses and two diametrically opposed cutouts forming one bayonet coupling part means, whereas the bayonet attachment of the mixer or accessory comprises two bayonet lugs corresponding to the cutouts. In a preferred embodiment the lugs and cutouts are of different widths for the coded alignment of the mixer or accessory to the cartridge in one predetermined position only.

Abstract: The mixer of the mixer-cartridge assembly comprises a housing, an inlet section having an individual inlet for each outlet of the cartridge and a mixer element group. The mixer inlet section comprising a separating element and the mixer element group are arranged thus, that while sealingly connecting the mixer to the cartridge, the inlets of the mixer remain aligned with the corresponding and matching outlets of the cartridge as well as with the separating element and with the dividing element of the mixer element group for optimizing the mixing of the components. For mixer attachment, the mixer housing comprises bayonet lugs cooperating with bayonet prongs on the cartridge, whereby the housing is rotated while the mixer inlet section, separating element and element group do not rotate in regard to the cartridge outlets, thus avoiding cross-contamination of the components at the cartridge/mixer interface and assuring continued separation well into the mixer up to the first dividing element.

Abstract: The metering device comprises a housing, defining at least one inlet for the material to be metered and at least one outlet for that material, and at least one rotatable ball driven by a shaft, the ball having a transverse bore containing a shuttling ball moving linearly in the bore between two seats and seals against the one or the other seat. The rotatable ball is captured between the seats and seals under pressure against the outlet seat. Such a metering device allows an exact metering, in shot or rapid shot resulting in near continuous flow form, has great simplicity of construction with few working parts such as that it may easily be placed at the dispensing end of a pressure transfer system for liquids and gases and acts as shut off valve between metering use such that it prevents stalled hydrostatic fluid pressure behind the metering device from causing a flow surge ahead of the metering device at start up.

Abstract: The device for the continuous monitoring of the correct proportioning and mixing of at least two fluids comprises a static or dynamic mixing device ending in a nozzle, wherein within the nozzle, the cross-sectional area of the stream or flow after the last mixing element of the static mixing device or at the end of the dynamic mixing device, as seen in the direction of flow, is substantially reduced compared to the cross-sectional area of the mixing part of the mixing device. This reduction is realized either by an internal volume displacing means or by reducing the diameter of the nozzle after the last mixing element of the static mixing device or at the end of the dynamic mixing device, and the nozzle being at a maximum transparency at the point of scanning. Such devices allow a more accurate monitoring since the greatest possible part of the stream of the mixed material can be more easily viewed or sensed.

Abstract: A manually operated appliance, particularly adapted for a two-component substance double dispensing cartridge, features two rams between which a thrust member is disposed in cylindrical sliding guides. Pivotably attached to the thrust member are ratchets, the pawls of which engage with an indentation extending on either side of each ram in order to move the rams, including the thrust pieces, in the direction of the cartridges. A thus guided thrust member, which is essentially movable only in parallel to the rams, provides for perfect force transmission and exact proportioning even when relatively great pressures occur and different diameters of the individual component cartridges are used.

Abstract: The end closure for the nozzle orifice of a dispensing cartridge for a two-component or multi-component system has at least two parallel stoppers which project from a common base and fit into the adjacent dispensing canals in the nozzle tube of the cartridge. For securing the closure to the cartridge in an axial direction, anchoring devices are provided to engage in the cartridge, such as lugs that permit elastic deformation, fitted with hooks or holding cams. At the junction with the base, each stopper has a continuous peripheral fillet. This acts conjointly with the edge of the orifice of the corresponding dispensing channel. The closure forms a secure seal for long-term storage and transport of the cartridge, is easy to use and inexpensive to make.
