Abstract: Waste wood is recycled into a large cross-section wood board without using a hazardous material as a binder. The invention provides a method for manufacturing a recycled wood product, and includes the steps of atomizing, to a wood material containing small wood chips, a mist of high-polymer agent having a natural component as the chief ingredient thereof, pressuring the wood material sprayed with the high polymer mist with the wood material aligned in the length direction thereof, and steam heating the wood material under a high-pressure environment to bond the adjacent wood chips together. A high-polymer agent containing tannin as a chief ingredient is used in one example. A high-polymer agent may be applied on the wood material.
Abstract: The present invention discloses a prosthetic bone implant made of a hardened calcium phosphate cement having an apatitic phase as a major phase, which includes a dense cortical portion bearing the majority of load and a porous cancellous portion allowing a rapid blood/body fluid penetration and tissue ingrowth.
Abstract: The present invention discloses a method for making a porous calcium phosphate article including i) preparing a shaped article from a paste containing a calcium phosphate cement, a pore-forming powder and a setting liquid; ii) immersing the shaped article in an immersing liquid for a period of time so that the pore-forming powder is dissolved in the immersing liquid, creating pores in said shaped article; and iii) removing the resulting porous shaped article from the immersing liquid, wherein the resulting porous shaped article has an improved compressive strength. The porous shaped calcium phosphate article of the present invention may be used as a tissue-engineered scaffold, medical implant or a reinforcing constituent of a composite.
Abstract: Processes of manufacturing polymeric microspheres facilitate the generation of polymeric microspheres of size ranges smaller than 600 microns diameter by forming beads of a predetermined size from a starting material which may include a template polymer, and subsequently contacting the beads with a structural polymer. After crosslinking of the structural polymer has taken place, the template polymer may be removed to form the finished microspheres.

Abstract: One of the exemplary filter systems described includes a bracket and a filter module that can be suspended from the bracket by a plurality of flexible supports. The bracket can support the filter system beneath the grate of a storm drain without the need for the filter system to be attached to the grate. The grate can be lifted out of the storm drain separately from the filter unit, which allows the filter system to be lifted without the added weight of the grate. When the grate has been lifted out of the way, a suitable fastener structure can be attached to the bracket of the filter system to make the use of mechanical lifting devices more convenient. The bracket can be manufactured to known dimensions, or it can be offered from among a set of brackets that are pre-configured for known storm drain dimensions or as a standard bracket that can be modified to fit the dimensions of a particular storm drain.
Abstract: The invention relates to a method of preparing a mineral fiber comprising one or more shaped cavities and a mineral fiber panel prepared by the method and an apparatus for preparing mineral fiber panels comprising one or more shaped cavities. Furthermore the invention relates to uses of the mineral fiber panel comprising one or more shaped cavities.
Abstract: Method for preparing a target substance in particulate form, comprising introducing into a particle formation vessel, through separate first and second fluid inlets respectively, (a) a “target solution/suspension” of the substance in a fluid vehicle and (b) a compressed fluid anti-solvent, and allowing the anti-solvent to extract the vehicle so as to form particles of the substance, wherein the anti-solvent fluid has a sonic, near-sonic or supersonic velocity as it enters the vessel, and wherein the anti-solvent and the target solution/suspension enter the vessel at different locations and meet downstream (in the direction of anti-solvent flow) of the second fluid inlet. Also provided is apparatus for use in such a method.

Abstract: Provided is an aerosol method, and accompanying apparatus, for preparing powdered products of a variety of materials involving the use of an ultrasonic aerosol generator (106) including a plurality of ultrasonic transducers (120) underlying and ultrasonically energizing a reservoir of liquid feed (102) which forms droplets of the aerosol. Carrier gas (104) is delivered to different portions of the reservoir by a plurality of gas delivery ports (136) delivering gas from a gas delivery system. The aerosol is pyrolyzed to form particles, which are then cooled and collected. The invention also provides powders that include particles made by the method and devices made using the particles.

Abstract: A method for forming a solidified granular material (15), in which granules (16, 17) are charged into a tubular frame member (11) and then heated together with the frame member, to solidify the granules. The granules include a mixture of first granules (16) and second granules (17), each of which second granules has a thermoplastic resin shell enclosing a solid or liquid which expands by vaporization. The mixture is charged into the frame member and heated together with the frame member. The heating causes the second granules (17) to expand and the surfaces of the second granules to melt for bonding with the first granules (16). The mixture, upon cooling, becomes a solidified granular material (15), filling the frame member with no space therebetween.

Abstract: A three-dimensional printer uses inkjet-type printheads to rapidly prototype, or print, a three-dimensional model. A powder feeder includes a conveyor system and a metering system to deliver powder to a build area in measured quantities. The powder feeder also includes a vacuum system for loading powder into a feed reservoir or chamber. The vacuum system can also be used to cleanup excess powder. Other powder control features include powder gutters and magnetic powder plows. During printing, a cleaning system operates to remove powder from the printheads. In the event of a printhead or jet failure, the failure can be detected and corrective measures taken automatically. After printing, the model can be depowdered and infiltrated in an enclosure.
