An implantable medical device includes a porous metal foam or foam-like structure having pores defined by metal struts or webs wherein the porous structure has directionally controlled pore characteristics. The pore characteristics controlled include one or more of the metal structure porosity, pore size, pore shape, pore size distribution and strut thickness. The pore characteristics may vary in one or more directions throughout the structure. Preferably the pore characteristics are controlled to match the porous metal structure to various mechanical and biological requirements of different regions of the structure in order to optimize aspects of the implants performance and may vary not only over the surface of the porous structure but through the depth of the porous structure. The thickness of the porous metal structure may also be modified to establish a thickness profile that optimizes mechanical and biological requirements of the implants performance. Acetabular cup embodiments of the invention are described. Various methods of manufacturing implants having directionally controlled pore characteristics are described.

A nanopatterned template for use in manufacturing nanoscale objects. The nanopatterned template contains a nanoporous thin film with a periodically ordered porous geomorphology which is made from a process comprising the steps of: (a) using a block copolymerization process to prepare a block copolymer comprising first and second polymer blocks, the first and second polymer blocks being incompatible with each other; (b) forming a thin film under conditions such that the first polymer blocks form into a periodically ordered topology; and (c) selectively degrading the first polymer blocks to cause the thin film to become a nanoporous material with a periodically ordered porous geomorphology. In a preferred embodiment, the block copolymer is poly(styrene)-poly(L-lactide) (PS-PLLA) chiral block copolymer, the first polymer is poly(L-lactide), and the second polymer is polystyrene. Experimental results show that the first polymer blocks can be formed into a hexagonal cylindrical geomorphology with its axis perpendicular to a surface of the thin film. After hydrolysis to selectively degrade the first polymer blocks, a thin film having a series of repeated nanoscale hexagonal-cylindrical channels is obtained.

The invention concerns an absorbent paper product with basic weight of about 36 to about 105 g / m2 comprising at least three pleats, a first and second outer embossed pleats each comprising raised patterns consisting at least partially of discrete protuberances oriented towards the inside of the structure and a non-embossed central pleat, the pleats being associated by linking the distal surfaces of at least part of the protuberances of each of the outer pleats to the central pleat. The invention is characterised in that each of the embossed outer pleats is linked by means of an adhesive to said central pleat, and at least one of the pleats has a pattern density more than 30 protuberances per cm2.

The present invention discloses methods and magnetic material composites capable of withstanding one or more loads without the need for a substructure to provide structural support thereto. The magnetic composites are formable from composites such as epoxies, resins, plastics and the like together with rare earth or other magnetic or magnetizable compounds, or magnetic nano-particles to form structural magnetic composites. The magnetic composites have one or more portions with an aggregation of the magnetic material and one or more portions free of or substantially free of the magnetic material. The magnetic composites are suitable for use to form components of electrical motors, generators, pumps, fans, paints, coatings and parts or derivatives thereof.

Plastic fibers and plant fiber such as thinned woods, scrap woods of buildings, stumps, branches or barks are stirred and mixed with each other into a felt-like material. Microwaves are radiated on the felt-like fiber mixture material. After a sufficient temperature is ensured for the felt-like fiber mixture material of low density by the microwave radiation, the fiber mixture material is fed to a pair of upper and lower pressure plates and compressed thereat. The fiber mixture material is rapidly compressed by the pressure plates so as to be melted and integrated. Then, the fiber mixture material is cooled so as to be further packed by such cooling, thereby becoming a stronger plastic fiber board.

A plastic cap comprising a top panel and a skirt hanging down from the peripheral edge of the top panel, the inner surface of the top panel forming an inner ring that forms a seal upon coming into intimate contact with the inner surface of the wall of the mouth of a container, and the inner surface of skirt forming a screw thread that comes into engagement with a screw thread formed on the outer surface of the wall of the mouth of the container, wherein a slender recessed portion is formed in a number of at least one in the inner surface of said inner ring extending upward from an end thereof. The cap features both excellent sealing and excellent venting.

Exhalation and inhalation valves that are sized and adapted to fit on a mask body of a personal respiratory protection device. The exhalation and inhalation valves comprise a valve seat that has a seal surface and an orifice through which an exhale flow stream may pass to leave the interior gas space. A flexible flap is mounted to the valve seat such that the flap makes contact with the seal surface when the valve is in its closed position and such that the flap can flex away from the seal surface during an exhalation to allow exhaled air to pass through the orifice to ultimately enter an exterior gas space. The flexible flap has at least first and second juxtaposed layers where at least one of the layers is stiffer or has a different elastic modulus than the other layer. These valves provide extraordinarily lower pressure drop in use, and they operate more efficiently and require less actuation power to operate. The end user therefore derives greater comfort when wearing a respiratory mask that uses the inventive valve.
