  • Patent number: 9869629
    Abstract: The present invention discloses a method and system for conducting high temperature corrosion tests on metallic alloys without the need for extensive laboratory equipment and attendant safety measures through the use of a two-compartment ampoule where a vestibule connects these two compartments. A pre-selected mixture of salts is placed in one compartment in order to generate a specific partial pressure of halogen gas; and a metallic alloy is placed in the other compartment. The ampoule is then heated to a pre-determined temperature and held at this temperature for a pre-determined time period. A halogen gas of a specific partial pressure is thereby generated from the mixture of salts which comes into contact with the metallic alloy. Because the ampoule creates a sealed environment, the metallic alloy is under constant halogenation during the pre-determined time period. The metallic alloy is removed for examination when the pre-determined time period expires.

  • Patent number: 9493981
    Abstract: A safety device for a window covering comprises a head rail and a shade panel extending from the head rail. A lift cord extends along one side of the shade panel between the head rail and the bottom of the shade panel. A safety device engages the lift cord to control the movement of the lift cord away from the shade panel. The safety device may also shroud the lift cord to limit access to the lift cord portion.

  • Publication number: 20160304993
    Abstract: The present application relates to systems and methods of producing ductile nickel-based austenitic alloy coatings. The methods may include using low levels of aluminum to form protective coatings, while retaining ductility. The method can include preselecting a desired thickness of coating to maximize the desired level of aluminum and ductility.

  • Patent number: 8328487
    Abstract: The present invention is directed to a retention element for retaining first and second components in assembled relationship. The first component comprises a body having first and second external surfaces and an inner wall defining an aperture extending through the body, and the second component comprises a longitudinal member having a size and configuration to permit insertion within said aperture to thereby assemble the components. The retention element comprises: an elastromeric protuberance extending into the aperture from a base adhering to the inner wall to a distal edge which spans a portion of the aperture. The protuberance also has an inside wall and an outside wall which meet at the distal edge and together define a flexible free end.
