International Classification:

E05D 5/02

US Classification:

16252, 16235, 16240, 16332

Abstract:

A side pivot hinge includes a joint body for securely mounting a side edge portion of the glass structure, a joint seat, having a joint sleeve, for securely mounting to a border frame, and an angular adjustment arrangement which includes a joint housing securely mounted to the joint body, a supporting shaft rotatably supported by the joint housing to rotatably insert into the joint sleeve to pivotally connect the joint body with the joint seat, and an angular adjustment locker to securely lock up the supporting shaft within the joint housing such that when the joint body is angularly moved with the joint seat for adjustably aligning the glass structure with the border frame, the supporting shaft is locked up at the joint housing in a rotatably movable manner via the angular adjustment locker for retaining an alignment of the glass structure in position with the border frame.

International Classification:

A61K 38/00
A61K 45/00

US Classification:

514 165, 424 852

Abstract:

A wound healing composition comprising an amount of heat shock protein effective to promote wound healing and a method thereof to apply the composition. A preferred heat shock protein is either full-length hsp90α or the middle domain plus the charged sequence of hsp90α. The composition is topically applied to skin wounds, covering the outer surface of the wound. The heat shock protein acts by promoting migration of both human epidermal keratinocyte and dermal fibroblasts to the wound in order to close, heal, and remodel the wound.

US Classification:

514 165, 424 852

Abstract:

A wound healing composition comprising a class of polypeptide compounds having a polypeptide chain with 5 to 120 amino acid units per chain. The composition includes a pharmaceutical medium to carry the polypeptide compound, such as an aqueous solution, suspension, dispersion, salve, ointment, gel, cream, lotion, spray or paste. Additionally, a method of applying a wound healing composition comprising a class of polypeptide compounds having a polypeptide chain with 5 to 120 amino acid units per chain in a concentration of from about 1 μg/ml to about 100 μg/ml for a time sufficient to heal the wound is disclosed.

International Classification:

B32B031/00

US Classification:

156057000

Abstract:

A attachment method for pressed flowers which includes the steps of: covering pressed flowers with a layer of transparent resin which becomes sticky when heated, attaching said pressed flowers to a surface of a base material, and indirectly heating said pressed flowers to make said resin become sticky thereby firmly adhering said pressed flowers to said base material without the use of adhesive and therefore making it easier and more convenient for decoration. It is also very convenient to separate the flower from the base material and heat it indirectly again to attach to another base material. The resin coating the flowers has the additional benefits of preventing the pressed flowers from color fading, wear and tear, and extending their usage.
