A valve assembly including a valve body, a sleeve member and a valve member is provided. A low shear sleeve member is positioned within an internal cavity of the valve body. The valve member is slidably carried within an internal cavity of the sleeve member. The valve member includes a first flow passage formed within the valve member and a first shut-off region. The valve member is moveable between a first position in which fluid flow from a first sleeve member inlet port to a first sleeve member outlet port is prohibited and a second position in which fluid flow from the first sleeve member inlet port to the first sleeve member outlet port is permitted. Delivery systems incorporating the valve assembly are also provided.
F16K 11/07 - Multiple-way valves, e.g. mixing valvesPipe fittings incorporating such valvesArrangement of valves and flow lines specially adapted for mixing fluid with all movable sealing faces moving as one unit comprising only sliding valves with linearly sliding closure members with cylindrical slides
F16K 3/314 - Forms or constructions of slidesAttachment of the slide to the spindle
F16K 27/04 - Construction of housingsUse of materials therefor of sliding valves
A static mixer is provided. The static mixer includes a plurality of static mixer elements. Each static mixer element includes a core extending axially along a longitudinal axis between a first end and a second end. Each static mixer element includes at least one blade around an outside of the core. At least a first one of the plurality of static mixer elements includes a first keying feature. At least a second one of the plurality of static mixer elements including a second keying feature configured to engage the first keying feature to prevent relative rotation between the first one of the plurality of static mixer elements and the second one of the plurality of static mixer elements about the longitudinal axes of the first one and the second one of the plurality of static mixer elements. Methods of forming the static mixer are also provided.
A molding system is provided. The molding system includes a resin source and a mold set. The mold set defines a cavity and includes an LED and a covering portion configured to separate the LED from the contents of the cavity. A light pipe portion is configured to deliver light from the LED to a portion of the cavity away from the LED. The mold set defines a resin input port through which the cavity is configured to receive resin from the resin source. The mold set includes a valve configured to prevent resin flow into the cavity in a closed configuration and to prevent light from the LED in the cavity from exiting the cavity through the input port when the valve is in a closed configuration. The molding system includes a controller configured to cause the LED to illuminate when the valve is in a closed configuration and to cause the LED not to illuminate when the valve is in an open configuration.
Methods and mechanisms for mixing and dispensing multipart materials is provided. The methods and mechanisms may be used for mix on demand operations as well as for encapsulation of electronic components. The methods and mechanisms may incorporate a mixer assembly from which material is substantially directly dispensed. The methods and mechanisms may incorporate mix on demand where first and second material supply sources include pumping arrangements for pumping first and second materials through a mixing arrangement. The pumping forces provided by the pumping arrangements also provide the force to dispense the mixed material where it will ultimately be formed, such as a potting location or a mold.
B01F 5/06 - Mixers in which the components are pressed together through slits, orifices, or screens
B01F 7/14 - Mixers with rotary stirring devices in fixed receptacles; Kneaders with stirrers rotating about a horizontal or inclined axis with stirrers having planetary motion
A thermal reservoir including a melting section and a heating arrangement is provided. A method of assembling is also provided. The melting section includes a plurality of material flow sections. Each material flow section includes a central cavity extending axially therethrough between first and second ends along a central longitudinal axis. The plurality of material flow sections are operably removably connected together with the central cavities thereof aligned and in fluid communication to form a material flow path extending through all of the connected material flow sections. The heating arrangement cooperates with the plurality of material flow sections to provide heat for heating a material to be passed through the material flow path.
A thermal reservoir including a heating section and an upper section is provided. The upper section defines a storage cavity. The upper section is formed from an insulated, non-stick or insulated non-stick material. The upper section is fluidly connected to the heating section and upstream from the heating section for receiving material to be heated prior to the heating section.
