Abstract: The invention is directed to a method for the encapsulation of liquids within a continuous impervious coating of thermoplastic material. The method is carried out with continuous agitation during which the adsorbent and adsorbate are coated with a plurality of sprayed layers of thermoplastic coating material while maintaining the adsorbent in free-flowing powder consistency during the coating steps. The method is especially advantageous for the encapsulation of volatile liquids.

Abstract: A suture locking fastener for surgical procedures. The one piece plastic molded fastener features a plurality of triangular-shaped leaves that are attached to a base. At least one of the leaves is attached to the base using a flexible hinge section thus permitting that leaf to articulate with respect to the base. The leaves are positioned at a predetermined angle relative to the horizontal that is at least 30 degrees, and, preferably, 45 degrees which permits a suture, either a thread or a plastic filament, to be held securely without deforming or cutting into it.

Abstract: A method and system of adaptive channel allocation in a frequency division multiplexed system is provided. In the method and system a subset of M subcarriers is chosen from a larger set of N subcarriers available for communications on a link. As communications take place on the link, signal quality (C/I) measurements on the subcarriers of the subset of M subcarriers and interference (I) measurements on the subcarriers of the group of N subcarriers are periodically performed. The C/I and I measurements are then used to reconfigure the subset of M subcarriers to reduce co-channel interference on the link.

Abstract: The invention relates to a folding box with self-adhesive seal and a method for sealing the folding box. The folding box has a cover (6) which can be locked in the sealing position at one of its free edges by a mechanical locking (10, 11), flaps (14, 15) that can be folded in under the cover, and contact adhesive strips (17) with covering strips (19) able to be pulled off, for gluing the cover (6) together with the flaps (14, 15). The covering strips (19) have at their free end a tab (19a) that protrudes from the closed folding box. By pulling on the tab (19a), the covering strips (19) can be pulled out laterally under the cover (6) locked in sealing position, in order to glue the cover (6) together with the flaps (14, 15). On perforated tear lines (23), the middle section of the cover (6) can be opened again, without having to undo the adhesive connection in doing so.

Abstract: The presence of a base in the reaction mixture in a metal-ligand catalyzed partial oxidation of alkanes results in sustained catalyst activity, and in greater percent conversion as compared with oxidation in the absence of base, while maintaining satisfactory selectivity for the desired oxidation, for example the oxidation of isobutane to isobutanol.

Abstract: The invention comprises a method for the oxidation of alkanes to alcohols and for decomposition of hydroperoxides to alcohols utilizing new compositions of matter, which are metal complexes of porphyrins.

Other preferred complexes are ones in which all four of the meso positions are substituted with haloalkyl groups and the beta positions are substituted with halogen atoms. A new method of synthesizing porphyrinogens is also disclosed.
