A process for manufacturing a rubber patch comprising a radiofrequency transponder, the patch having a first layer and a second layer, the method comprising moulding and vulcanizing a first layer, the exterior surface of which comprises a cavity able to receive a radiofrequency transponder, placing a transponder in the cavity, and then placing and vulcanizing a second layer in order to embed the transponder between the two layers.

A curable composition containing more than 80% by weight of a blend of benzoxazines, wherein the blend includes (A) one or more multifunctional benzoxazines and (B) a liquid, non-halogenated monofunctional benzoxazine. This composition has been found to be stable at high temperatures, e.g. 180° C.-250° C., and suitable for making composite materials using conventional techniques such as prepregging and liquid resin infusion.

Disclosed is a micro-needle including a tip formed using medicine that penetrates into the skin and melts therein; and at least one guide groove each in a stepped shape inward from the outer surface of the tip, and provided to the tip. The micro-needle configured as above may be used to administer a fixed quantity of medicine within a relatively short period of time. Also, since a guide space stepped based on the tip is provided to a base that supports the tip, a large amount of medicine may easily penetrate into the skin.

Materials including support layers and fiber-free compositions are disclosed, as well as related articles and methods for making the materials. The fiber-free compositions are formed from a precursor composition that includes a nitrile butadiene rubber, a nanoclay and a cure package including a sulfur-based curing agent. The fiber-free compositions may have a substantially reduced weight and compressive modulus in comparison to conventional rubber. Thus, the fiber-free compositions may provide improved ballistic properties in addition to reduced density and thickness. Precursor compositions for forming the insulative composition may have good flow characteristics. The fiber-free compositions may be used in a variety of applications, such as personnel body armor, ground vehicle armor and aircraft armor systems.

A method for producing a collagen-containing sheet material, wherein a collagen-containing suspension is dried in such a manner that the collagen settles during drying and forms a transparent skin.

A needle-shaped structure includes a needle-shaped projection and a support substrate supporting the projection wherein the projection contains at least a chitosan and an organic acid, places a low burden on a living body and is able to keep the microscopic form after puncture into the skin.

The present application discloses and claims a method to make a flexible ceramic fibers (Flexiramics™) and polymer composites. The resulting composite has an improved mechanical strength (tensile) when compared with the Flexiramics™ alone. Several different polymers can be used, both thermosets and thermoplastics. Flexiramics™ has unique physical characteristics and the composite materials can be used for numerous industrial and laboratory applications.

This invention relates to the use of composite reinforcements advantageously comprising a thermosetting matrix and a filler in particular in the reinforcing of thermoplastic material or of thermosetting resin, in order to obtain a reinforced structure such as a bathtub, a washbasin, a wall panel or a shower tray.

This invention relates more particularly to a method for preparing a reinforced structure using composite reinforcements, as well as the structure able to be obtained by such a method.

The present disclosure provides processes for producing polyethylene resins. In at least one embodiment, a polyethylene has: a density of from about 0.91 g/cm.sup.3 to about 0.94 g/cm.sup.3; a value of Mz of about 1,500,000 g/mol or greater; and a ratio of Mz to Mw of about 7 or greater. A process includes introducing a first feed stream having ethylene monomer and a first free radical initiator to a first inlet of a first reaction zone, where the first reaction zone has a first inlet temperature. The process further includes introducing a second feed stream having ethylene monomer and a second free radical initiator to a second inlet of a second reaction zone, where the second reaction zone has a second inlet temperature that is the same or different than the first inlet temperature.

Provided is a hookah holder comprising: a) a ring configured for accepting a base of a hookah; b) a plurality of connectors on a bottom of the ring for securing the ring to a surface; wherein the hookah's base in placed inside of the ring and is secured by the hookah holder. The connector can be a suction cup. The suction cups can be spaced apart and arranged in a concentric fashion in relation to the ring. The hookah holder can be made from silicone. The hookah holder can be fabricated from one piece. The hookah holder can be manufactured by casting silicone in a cast. The ring can have a diameter of about 100 mm to about 200 mm. The cavity can be formed inside of the ring and be configured to receive a hookah base. The ring can have an upper portion and a lower portion, with a cavity formed by the upper and the lower portion, the cavity configured to receive a hookah base. The lower portion can extend more towards center of the ring than the upper portion. The cavity can have a shape of a V with a curved bottom.
