Abstract: A fastener includes a clamp arm which is connected with a base. The clamp arm cooperates with the base to form an entrance into which an article extends. A first locking tab extends from the base into a first opening in the article. A second locking tab extends from the clamp arm into a second opening in the article. When a withdrawal force is applied to the fastener, an arcuate portion of an inner side surface of the clamp arm moves from a position spaced from an outer side surface of the article to a position in which the arcuate portion of the inner side surface of the clamp arm is disposed in abutting engagement with the outer side surface of the article.

Abstract: A fastener (10) includes a clamp arm (26) which is connected with a base (24). The clamp arm (26) cooperates with the base (24) to form an entrance (80) into which an article (14) extends. A first locking tab (40) extends from the base (24) into a first opening (64) in the article (14). A second locking tab (120) extends from the clamp arm (26) into a second opening (142) in the article. When a withdrawal force is applied to the fastener, an arcuate portion (116) of an inner side surface (108) of the clamp arm (26) moves from a position spaced from an outer side surface (164) of the article (14) to a position in which the arcuate portion of the inner side surface of the clamp arm is disposed in abutting engagement with the outer side surface of the article.

Abstract: Disclosed is a system for storing and recovering energy, the system comprising an energy capturing device, a storage vessel operably linked to the energy capturing device, the storage vessel adapted to receive and store energy captured by the energy capturing device, and an energy recovery device adapted to receive the stored energy from the storage vessel, the energy recovery device operable to convert the stored energy to electrical energy. The energy recovery device is in electrical communication with an existing electrical infrastructure, whereby the electrical energy is delivered to a population.

Abstract: A very pure, dust-free commercial form of 4,2',4'-trichloro-2-hydroxydiphenyl ether with little odor is prepared by diazotizing 4,2'4'-trichloro-2-aminodiphenyl ether, boiling the diazonium salt and purifying the reaction product.
