A nozzle tip assembly comprises a nozzle housing and a break-up insert. The nozzle assembly is adapted for receiving multiple pre-cursor fluids from multiple lumen. The pre-cursor fluids are kept substantially separate and forced around the break-up insert into a channel formed between the insert and the nozzle housing. Fluid is forced into fluted channels on a distal end of the break-up insert into a swirl chamber where mixing occurs prior to being expelled through an exit orifice in the nozzle housing.

A manually drivable device for the mixing of a pasty mixing ware from at least two fluid starting components comprising at least two cartridges having feed plungers; a mixing space to mix the starting components, mixing vanes being provided in the mixing space and mounted such that they can rotate; a lever rotatable about a pivot point operatable manually or a pin that can be shifted in longitudinal direction and operatable manually in order to operate the device; a gear connected to the lever or pin, and connected to the rotatable mixing vanes in the mixing space; and a facility for propelling the feed plungers such that the motion of the lever or pin drives the rotation of the mixing vanes in the mixing space and motion of the feed plungers into the cartridges. The invention also relates to a method for mixing fluid starting components using the device.

This invention is a low pressure, steady volume supply static mixer manifold for a high pressure pump. The design comprises an internal diffuser cylindrical tube inside an external rectangular tube in which static mixing occurs. Capped at one end, the internal diffuser pipe, with flow coming from the opposite side, allows for one flow direction diffused into the outer rectangular tube that then allows for constant bidirectional flow at a constant pressure throughout. The flow of slurry components between the cylindrical tube and the rectangular tube supports static mixing in part by creating alternating flow pressures between mixing ports (allowing flow of slurry components from the cylindrical tube) and the exit ports based on the different geometries of the cylindrical tube and rectangular tube. The combination of flow and pressure exiting the cylindrical tube through the mixing ports, at an angle to the bottom corners of the outer rectangular tube, creates a natural agitation of the slurry components. The cutouts in the inner tube are sized and spaced for providing the proper flow, mix, and pressure to each exit port.

A dispensing device is provided that has a nozzle that can mix together liquid reactants to dispense an expandable foam substance through concrete structures. The device features a liquid storage portion, a mixing portion and a dispensing portion. The storage portion includes liquid storage chambers in communication with a liquid passageway. The mixing portion has a mixing tube and a static mixer. The mixing tube has an elongated body with an interior passageway between opposing first and second ends. The static mixer is housed within the interior passageway of the mixing tube and features a plurality of curved baffles. The dispensing portion has a reservoir and a nozzle tip. The reservoir features a first end secured to the mixing tube and a second end communicating with a nozzle tip. The nozzle tip features a plurality of tine segments with each segment having a distal tip with an external gripping flange.

A mixing hub for use in semiconductor processing tools is provided. The hub may include a plurality of ports arranged about an axis, a mixing chamber, and a plurality of flow paths. Each of the flow paths may fluidically connect a corresponding one of the ports to the mixing chamber and each flow path may include a first passage, a second passage, and a valve interface. Each valve interface may be configured to interface with a valve such that the valve, when installed in the valve interface, is able to regulate fluid flow between the first passage and the second passage. Each valve interface may be located between a first reference plane that is perpendicular to the axis and passes through the corresponding port and a second reference plane that is perpendicular to the axis and passes through the mixing chamber.

An apparatus includes a selectively actuated fluid system having a plurality of selected fluid reservoirs, for example replaceable cartridge-type fluid reservoirs. A first subset of the reservoirs can be selectively actuated to dispense an individual fluid from the selected reservoir. A second subset of the reservoirs can be simultaneously actuated to dispense two or more fluids in mixed form.

A portable mixer for medication and/or dental impression material includes a gear assembly and an upper lid. The gear assembly comprises a helical gear with a bidirectional bearing, a clutch shell with a unidirectional bearing meshing with the helical gear, a spring positioned between the helical gear and the clutch shell, two pinions respectively positioned beside the clutch shell and the helical gear, and a shifting shaft mounted transversely through each of the two pinions, the helical gear, the bidirectional bearing, the spring, the unidirectional bearing, and the clutch shell. The upper lid comprises a fastener and a switch cover co-acted with the fastener and detachably contacting the helical gear and the clutch shell.

A device for applying an at least two-component viscous material to workpieces, includes a metering unit which has a number of metering valves corresponding to the number of components of the viscous material, and a static mixer which has a mixing tube, for mixing the components introduced using the metering unit into a material inlet at its first end and during passage from the material inlet to a material outlet at its second end, and an outer tube, wherein the mixing tube is received in the outer tube and, at the material inlet and at the material outlet, is sealed off from the environment using respective seals. The seals each have a circumferential cutting edge, and the cutting edges, when subjected to force in a direction towards each other, each cut into an end face on the mixing tube.

A device for storing and mixing bone cement components. The device includes a housing, a safety device, and a vacuum indicator. The housing defines a mixing chamber configured to store a first bone cement component therein. In a first safety position, the safety device prevents contact between the first bone cement component and a second bone cement component in the mixing chamber. In a second safety position, the safety device permits contact between the first and second bone cement components in the mixing chamber. The vacuum indicator restricts movement of the safety device from the first safety position to the second safety position when in a first vacuum indicator position. The vacuum indicator permits movement of the safety device from the first safety position to the second safety position when in a second vacuum indicator position.
