  • Patent number: 7716891
    Abstract: Panels (20A, 20B) are attached to extrusions (66A, 66B) by fasteners 90. Clips (70) are attached to a structure (50) by fasteners (35). The extrusions and the clips engage in a manner which allows the panels to move in any direction, as needed, without the panel detaching from the structure and falling. The extrusions also provide for the use of optional reveal strips (87). An extrusion has a restraining area (86), a reveal strip stop area (58), and a T-slot (65). A clip has a T-channel (74), a tensioning stop arm (69), and a secondary reinforcing arm (80). The panels can be installed in rows, in columns, or diagonally, as desired.

  • Patent number: 6058943
    Abstract: The present invention provides a process by which smoothness, body and a permanent wave pattern can be imparted to multi-textured hair of all types, from hair having an excessively tightly curled appearance, such as Negroid hair, to hair having a straight appearance, such as Caucasian hair, with substantially less damage to the hair. The process of the present invention uniquely combines the use of two hair structure altering chemicals--an alkaline hydroxide (such as sodium hydroxide) and a thioglycolate reducing agent (preferably ammonium thioglycolate)--to harmoniously bring about a desired wave pattern in the hair. Using the Wave Balance Scale (a hair reference scale) of the present invention, a sodium hydroxide formulation is chosen based on the type and natural curl level of the hair. The sodium hydroxide formulation is applied to the hair for a time sufficient to relax the natural curl in the hair by breaking some of the sulfide bonds in the hair.

  • Patent number: 6004519
    Abstract: The recovery of aluminum chloride from deactivated alkylation catalyst complexes by hydrogenation using hydrogen gas and an aluminum catalyst is disclosed. Using aluminum to catalyze the hydrogenation allows the reaction to proceed at a lower temperature and pressure while reducing the amount of hydrogen chloride present in the reactor thus reducing the corrosiveness and cost of the aluminum chloride recovery. Methods for batch, batchwise continuous, and continuous aluminum chloride recovery are disclosed.

  • Patent number: 5855832
    Abstract: A high density fiber product is made from natural lignin containing plant fibers. Plant fibers ranging in size below about 3000 microns in diameter are used. Binding agents and other additives may be mixed with the fibers to enhance product or process performance. The plant fibers or mixture of fibers and additives are heated to between about 50 degrees C. to about 140 degrees C. The heated fibers are compressed in a mold to an average density of about 50 pounds per cubic foot to about 100 pounds per cubic foot. Compression pressures of about 500 psi to about 2500 psi are used to achieve product densities within this range. The compressed fibers are cured under these temperature and pressure conditions. After the curing time has elapsed, the compressed fiber product is released from the mold and the mold may be reused. A high density product made from small plant fibers is provided.
