  • Publication number: 20170284122
    Abstract: An awning arm assembly is provided that includes inner and outer arms. A joint is provided that has an axle, e.g., any structure about which rotation can be provided coupled with one of the inner arm and the outer arm and a hollow body disposed about the axle. The hollow-body is coupled with the other of the inner arm and the outer arm. The hollow body is coupled with the axle such that when the outer arm moves relative to the inner arm the angle between the hollow body and the axle (and thereby the inner and outer arms) is adjusted.

  • Publication number: 20170112242
    Abstract: An umbrella hub is provided that comprises an inner portion, an outer periphery, a lower portion and an upper portion. A plurality of vertical grooves is disposed in the outer periphery and is configured to receive umbrella ribs or struts. A plurality of grooves extends transverse to the vertical grooves. A retention member is disposed in each of the transverse grooves. A first configuration of the hub permits deflection of the retention member such that a transverse pin coupled with the umbrella ribs or struts can be inserted into the transverse groove in which the retention member is disposed. A second configuration of the hub prevents deflection of the retention member such that inadvertent withdrawal of the pin from the transverse groove in which the retention member is disposed is prevented.

  • Patent number: 9422486
    Abstract: The present invention relates to a selective hydrogenation catalyst for an unsaturated compound. The supported catalyst contains at least one Group VIB non-noble metal oxide and at least one Group VIII non-noble metal oxide deposited on a carrier; and the catalyst has an optimized acid distribution on the surface of the catalyst, and more preferably has an optimized Group VIII/VIB metal ratio and a Group VIII non-noble metal density per unit of catalyst surface area. Using the catalyst of the present invention can have the following advantages: the weight increase of light sulphides in an unsaturated compound or a mixture containing unsaturated compounds, the hydrogenation of a polyunsaturated compound, the isomerization of a monounsaturated compound, high operation flexibility and a significant improvement in the effects of a hydrogenation treatment.
