A head is disclosed for use with a manufacturing system. The head may have a housing configured to discharge a tubular structure reinforced with at least one continuous fiber and having a three-dimensional trajectory, and a cure enhancer operatively connected to the housing and configured to cure a liquid matrix in the tubular structure during discharge. The head may also have a nozzle configured to discharge a fill material into the tubular structure, and a wand extending from the housing to the nozzle.

A system is disclosed for use in manufacturing a composite structure. The system may include a support configured to move in a plurality of directions during manufacturing of the composite structure, and a head coupled to the support. The head may have a housing that is configured to receive a liquid matrix and at least one continuous fiber and configured to discharge a tubular structure. The head may also have a nozzle operatively connected to the housing and configured to deposit a material layer onto a surface of the tubular structure as the tubular structure is discharging from the housing, and a squeegee associated with the nozzle and configured to wipe over the material layer. The head may further have a first cure enhancer operatively connected to the housing and configured to cure the liquid matrix in the tubular structure during discharge, and a second cure enhancer configured to cure the material layer deposited by the nozzle.

A head is disclosed for use with a continuous manufacturing system. The head may have a housing, a fiber guide rotatably disposed at least partially inside the housing, and a diverter disposed at an end of the housing. The diverter may be configured to divert radially outward a matrix-coated fiber passing through the fiber guide.

An atomization device including a pair of counter-rotating rollers, a fluid source configured to coat at least one of the rollers in a feed fluid, and a baffle unit. The counter-rotation of the rollers stretches the feed fluid into a fluid filament between the two diverging surfaces of the rollers. The stretched fluid filaments breaking into a plurality of droplets at a capillary break-up point of the feed fluid. The baffle unit introduces a baffle fluid within the interior of the device, the baffle fluid transporting formed droplets of the feed fluid from the atomization device. Excess or misguides atomized fluid droplets are collected by the baffle unit and are recycled back into the device for use in later atomization processes. The variation of atomization device parameters allows for the selection of droplets having desired physical parameters.

A method of atomizing a fluid using a pair of counter-rotating rollers including a first roller having grooves, the grooves enclosed by a pair of fins extending away from the first surface and a second roller having channels, the first and second rollers aligned with each other such that the grooves of the first roller mate with the channels of the second roller forming enclosures and nips. The method includes drawing the fluid from a fluid source through the nips, the nips having an upstream side and a downstream side, stretching the fluid between the diverging surfaces of the pair of counter-rotating rollers on the downstream side of the nips to form fluid filaments, and forming fluid droplets from the stretched fluid filaments on the downstream side of the nips between the diverging surfaces of the pair of counter-rotating rollers.

A brewing chamber cleaner including a spinning or stationary assembly for spraying cleaning solution into the brewing chamber. The spinning assembly may be attached to a disk configured to removably reside in the brewing chamber, or be part of a coffee maker. Liquid pumped into the brewing chamber cleaner may cause the spinning assembly to spin by the liquid flowing past gears or a propeller, or by off center jets on the spinning member. Alternatively, the coffee maker includes a rotating shaft to cause the spinning assembly to spin or may include stator winding creating a rotating magnetic field to cause the spinning assembly to spin. In another embodiment the brewing chamber cleaner includes a wide spray provided by a fixed nozzle. A base is optionally provided to capture the spray and direct a flow into a bottom extraction needle of the coffee maker to clean the extraction needle.

A method of forming particles that includes performing a strong force attenuation of a mixture to form pre-particles. The mixture including a base compound and a dielectric additive having an elevated dielectric constant dispersed therein. The pre-particles are then dielectrically spun in an electrostatic field to further attenuate the pre-particles and form the particles.
