  • Patent number: 8216964
    Abstract: The present invention addresses at least four different aspects relating to catalyst structure, methods of making those catalysts and methods of using those catalysts for making alkenyl alkanoates. Separately or together in combination, the various aspects of the invention are directed at improving the production of alkenyl alkanoates and VA in particular, including reduction of by-products and improved production efficiency. A first aspect of the present invention pertains to a unique palladium/gold catalyst or pre-catalyst (optionally calcined) that includes rhodium or another metal. A second aspect pertains to a palladium/gold catalyst or pre-catalyst that is based on a layered support material where one layer of the support material is substantially free of catalytic components. A third aspect pertains to a palladium/gold catalyst or pre-catalyst on a zirconia containing support material.

  • Patent number: 7829010
    Abstract: An end-piece for an additive guide tube is disclosed. Such an end piece may have a durable sleeve and a sloughable sleeve. The sloughable sleeve may have a channel through which an additive may be delivered, and the sloughable sleeve may reside in the through-hole of the durable sleeve and may be secured to the durable sleeve. When molten metal contacts the sloughable sleeve, the sloughable sleeve burns or melts and sloughs off, thereby preventing the molten metal and slag from sticking to the end-piece, which in turn prevents buildup of metal and slag.

  • Patent number: 7533897
    Abstract: An assembly is provided for steering a vehicle including a driver interface operable to enable a driver to steer the vehicle and at least one control member operable to couple the driver interface to the vehicle. An air bag module is coupled to the driver interface and is operable to expand to absorb the kinetic energy of the driver. A horn switch is coupled to the driver interface and the air bag module. The horn switch is operable to generate an electrical signal based on an input from the driver. An attachment mechanism is operable to couple the air bag module and horn switch to the driver interface, and includes at least one retaining member operable to engage the air bag module and armature. The retaining member is operable to release the air bag module and horn switch from the driver interface upon the application of a retractive force.

  • Publication number: 20080314201
    Abstract: The present invention provides increased recovery in additive-enhanced or alloy-enhanced molten steel. This is accomplished by dispersing agents blended with the additive alloys. The dispersant powder reacts with the carbon in the steel forming carbon monoxide gas which provides kinetic energy to the additive alloy particle causing dispersion within the molten bath, resulting in greater dissolution of the particles in the molten bath. The alloy or additive region is enriched, thereby improving the recovery in the molten steel.

  • Publication number: 20080314199
    Abstract: The present invention provides increased recovery in additive-enhanced or alloy-enhanced molten steel. This is accomplished by deoxidizing powders blended with the additive alloys. The deoxidizing powder reacts with the oxygen, thereby depleting the oxygen in this region. The alloy or additive region is enriched, thereby improving the recovery in the molten steel.

  • Publication number: 20060135809
    Abstract: The present invention relates to a method of producing a catalyst or pre-catalyst suitable for assisting in the production of alkenyl alkanoates. The method includes contacting a modifier precursor to a support material to form a modified support material. One or more catalytic component precursors (palladium or gold) may be contacted to the modified support material. The atomic ratio of gold to palladium is preferably in the range of about 0.3 to about 0.90. The support materials with the catalytic component may then be reduced using a reducing environment. A composition for catalyzing the production of an alkenyl alkanoates including a modified support material with palladium and gold is also included within the invention. Catalysts of the present invention may be used to produce alkenyl alkanoates in general and vinyl acetate in particular and are useful to produce low EA/VA ratios while maintaining or improving CO2 selectivity.

  • Publication number: 20030151292
    Abstract: This invention relates to four part furniture frames having a seat box portion, a back portion and two arm portions. The unique tapered side edges on the seat box portions of these frames allows the seat box portion to be nested with the separate back portion, thereby forming a substantially flat rectangle. The unique notches on the back upright supports posts of these frames support the back spring rail of the seat box portion, allowing the seat stretchers to be uniquely made of plywood or oriented strand board instead of oak. The light weight frames of this invention may be incorporated into both ready-to-assemble furniture and fully assembled upholstered furniture. These light weight, economical, nestable frames may be easily stacked, packed and shipped. Additionally, these frames may be easily assembled, by a furniture manufacturer, a store, a customer, or anyone else, with only eight easy-to-use connectors such as bolts and T-nuts.
