A head is disclosed for use with a continuous manufacturing system. The head may have a housing configured to receive a matrix and a continuous fiber, and a diverter located at an end of the housing. The diverter may be configured to divert radially outward a matrix-coated fiber. The head may also include a cutoff having an edge configured to press the matrix-coated fiber against the diverter.

An injector head for an anti-icing system may comprise a body having a first surface, a second surface, a face, and an inlet, a first sweeping jet nozzle having a first exit port through the face, wherein the first sweeping jet nozzle comprises a fluid oscillator defining a first sweeping plane of the first sweeping jet nozzle, and a distribution manifold within the body in fluid communication with the inlet and the first sweeping jet nozzle.

A method and apparatus is disclosed for additive manufacturing and three-dimensional printing, and specifically for extruding tubular objects. A print head extrudes a curable material into a tubular object, while simultaneously curing the tubular object and utilizing the interior of the cured portion of the tubular object for stabilizing and propelling the print head.

A control system for devices driven by or utilizing decompressing air is provided. The system includes a supply of compressed air connected to a compressed air-utilizing device. A source of heated fluid is provided and is connected to a heat exchanger that transfers heat from the heated fluid to the compressed air. The compressed air is heated in the heat exchanger sufficiently that upon decompression the temperature of the device is not lowered to the ambient dew point. The system is particularly applicable to devices utilizing compressed air for the spraying of liquid materials

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 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 coating including a substrate and a plurality of hydrophobic silver particles disposed on the substrate. The contact angle of the coating with water at room temperature is between 152 and 162 and the resistance value of the coating is between 10.sup.1 and 10.sup.3.

An injector head for an anti-icing system may comprise a body having a first surface, a second surface, a face, and an inlet, a first sweeping jet nozzle having a first exit port through the face, wherein the first sweeping jet nozzle comprises a fluid oscillator defining a first sweeping plane of the first sweeping jet nozzle, and a distribution manifold within the body in fluid communication with the inlet and the first sweeping jet nozzle.

The invention provides an assembly for processing a pipe section for a pipeline, in particular for coating said pipe section, said assembly having a longitudinal axis which in use functionally coincides with a rotational axis of said pipe section, said assembly comprising a surface-heating device for heating a surface, said surface-heating device comprising at least one heating module, said heating module comprising at least one infrared (IR) radiation laser device, said surface-heating device arranged for projecting a beam of said at least one infrared (IR) radiation laser device at said longitudinal axis for in use heating a ring-section of a surface of said pipe section.

A sprinkler head for use in a structure for the delivery of a liquid includes a housing, a sleeve, a cap, a spray assembly, a return spring and an SMA spring. The sleeve includes a first portion which is positioned in the housing. The cap is threadedly assembled with the housing. The spray assembly is assembled to a second portion of the sleeve. The return spring is positioned between the cap and the first portion. The SMA spring is positioned between the cap and the spray assembly. The sleeve is movable relative to the housing in order to open a liquid flow path due to activation of the SMA spring resulting from an elevated temperature.
