A wax melt blank is produced with an extrusion process and intended to later be cut to length into individual wax melts. The wax melt blank includes at least about fifty percent by weight of wax, a fragrance, and up to about fifty percent by weight of a filler. The wax, the fragrance, and the filler are homogeneously dispersed within the wax melt blank.

To obtain a liquid crystal polymer film having a small in-plane linear expansion coefficient. A liquid crystal polymer pellet contains a liquid crystal polymer and is used as a material of a liquid crystal polymer film. The liquid crystal polymer pellet has an orientation degree of 86% or more as measured by wide-angle X-ray scattering.

A method of manufacturing a polymer film includes melting a resin, extruding the melted resin through a die to produce a polymer film, shaping the polymer film, cooling the polymer film, capturing an image of a test pattern through the polymer film, calculating a modulation transfer function value from the image, and adjusting a process parameter of the melting, the extruding, the shaping, or the cooling based on the calculated modulation transfer function value.

The machine includes an extrusion head having flow ducts, the inlet orifices of which are connected to the outlets of at least two extruders for supplying extruded strips made of elastomeric compounds. The outlet orifices lead into a die which is adjacent to a roller and is designed to cooperate with the latter to shape the profiled element strip. The roller has a central axis surrounded by an external surface intended to receive the profiled element strip and a means for driving the roller in rotation about its central axis. The flow ducts are mutually parallel and are perpendicular to the circumferential direction of the roller, and the profiled element strip is joined to the receiving surface of the roller along an equivalent length of at least 700 mm.

An extruding process and assembly for creating a structural form, which includes the steps of bundling and conveying at least one length of a material into an extruder, reshaping a cross section of the bundle in a first stage of the extruder, extruding a material using any combination of heat and pressure around and between the lengths of material, and outputting a finished article having a cross sectional profile in which the materials are structurally supported by the extruded and hardened material. Other steps include an intermediate chilling stage between reshaping and extruding, and for preventing the extruded material from back flowing. The extruded material further includes any of a polymeric or structural foam material and can exhibit any of a rounded, square, rectangular or I beam cross sectional profile.

A carriageless print head assembly, for use in extrusion-based additive construction is disclosed. The carriageless print head features a cold end equipped with one or more timing belt attachment slots and bores for receiving bearings to achieve linear motion. The carriageless print head may be optionally equipped with some combination of an air conduit for cooling the top layer of the constructed product, a fluid channel for aiding in the regulation of the temperature of the print head cold end, and a thermal monitor for monitoring the temperature of the cold end of the print head. A computer-mediated method of monitoring the cold end of the print head to limit jams due to overheating is also disclosed.

A compressible biomass carrier for use in fluid treatment systems is disclosed. The biomass carrier includes an extruded circumferential mesh-like structure and elongated elements positioned in a space confined by the circumferential mesh-like structure and at least some of the elongated elements are joined to an inner portion of the mesh-like structure.
