A method for forming a thermoplastic body having regions with varied material composition and/or porosity. Powder blends comprising a thermoplastic polymer, a sacrificial porogen and an inorganic reinforcement or filler are molded to form complementary parts with closely toleranced mating surfaces. The parts are formed discretely, assembled and compression molded to provide a unitary article that is free from discernible boundaries between the assembled parts. Each part in the assembly has differences in composition and/or porosity, and the assembly has accurate physical features throughout the sections of the formed article, without distortion and nonuniformities caused by variable compaction and densification rates in methods that involve compression molding powder blends in a single step.

An assembly for densification under load along at least one direction of compression. The assembly includes: at least one volume to be densified having a powdery and/or porous composition and having variations in thickness along the direction of compression; and at least one counter-form of a powdery and/or porous composition, having at least one face facing at least one portion of the volume. The face and each of the portions are separated by at least one deformable interface layer.

A process is provided for producing a structure into which blood or other bio-fluids can flow by capillary action, e.g. for a whole blood microsampling probe. The process comprises mixing particles of novolak resin and particles of hydrocarbon polymer, producing an uncarbonized structure from the mixture by pressurised moulding and carbonizing the moulded structure, the hydrocarbon resin being a polymer such as polystyrene that on pyrolysis has a zero carbon yield, and the particles of the hydrocarbon polymer leaving voids in the carbonized structure of sufficient size for flow of whole blood into and through the structure. The particles may be of partly cured and milled novolak resin, the novolak particles when in the moulded structure not exhibiting bulk flow during carbonization but sintering at inter-particle contact points during carbonization to provide a consolidated structure. In this variant, ethylene glycol may be used as a sintering aid. Alternatively, the particles may be of fully cured and milled novolak resin, and are mixed with the hydrocarbon polymer , the lubricant and with a binder such as lignin for providing a consolidated structure.

A process for manufacturing an article made of recovered rubber crumb is provided. According to the process:

a) crumb particles are mixed with particles of a solute;

b) a molded article is produced by molding the mixture from step a) in a closed mold under predetermined temperature and pressure conditions; and

c) the molded article is brought into contact with a solvent so as to dissolve at least one portion of the particles of said solute.

A compression device, means for controlling the compression device, a drum having an inner chamber, means for rotating the drum, and first and second delivery devices for delivering first and second materials into the inner chamber of the drum while the drum is rotating. The compression device compresses the first and second material in the inner chamber of the drum while the drum is rotating about the center of the drum in response to the means for controlling the compression device. The apparatus may include a stirring device; and a means for controlling the stirring device; wherein the stirring device is configured with respect to the drum so that the stirring device can be moved up and down to a desired depth within the drum and rotates within the inner chamber of the drum to stir the first and second materials in the drum while the drum is rotating.

Drug tablets that include a controlled release layer of a moisture-sensitive active agent are prepared with a lipidic matrix forming excipient, a water-soluble, channel forming excipient and a filler, each being non-hygroscipic. The tablets are formed in a process where the components are blended in the absence of moisture and in particulate form.

The invention relates to a method of manufacturing components, comprising the steps of: a) manufacturing a component blank in an additive manufacturing process, comprising: a1) determining component regions of the component blank to be cured in an electronic planning process and generating a component blank data set defining the component regions to be cured, a2) arranging a raw material and selectively curing and joining the raw material in the component regions to be cured on the basis of the component blank data set to form the component blank, wherein the curing and joining of the raw material on the basis of the component blank data set is carried out such, that the component blank has a component blank density which is less than 99.5% of the density theoretically achievable with the raw material, b) compacting and solidifying the component blank to form a component in a hot isostatic pressing process, in which the component blank is heated in a furnace chamber to a temperature below the melting temperature of the raw material and is pressed by generating an overpressure in the furnace chamber by means of a furnace chamber pressure of at least 50 bar.

A method of forming a polyolefin-perovskite nanomaterial composite which contains oriented electrically and thermally conductive pathways. The method involves milling a polyolefin with particles of a perovskite nanomaterial, molding to forma composite plate, and subjecting the composite plate to an AC voltage. The AC voltage forms oriented electrically and thermally conductive pathways by partial dielectric breakdown of the composite. The presence of the oriented electrically and thermally conductive pathways gives the polyolefin-perovskite nanomaterial electrical and thermal conductivity and dielectric permittivity higher than the polyolefin alone.

A method for forming a vacuum insulated structure using a prepared core material includes preparing a powder insulation material defining a bulk density, pre-densifying the powder insulation material to form a pre-densified insulation base, crushing the pre-densified insulation base into granular core insulation to define a core density of the granular core insulation, disposing the granular core insulation having the core density into an insulating cavity defined within an insulating structure and expressing gas from the interior cavity of the insulating structure to further densify the granular core insulation to define a target density. The granular core insulation defines the target density disposed within the insulating structure defines the vacuum insulation structure, wherein the target density defines a density in the range of from approximately 80 grams per liter to approximately 350 grams per liter.
