  • Packing element
    Patent number: 5660767
    Abstract: The invention provides highly deformation resistant Lessing rings made in two parts. The first part comprises a metal strip bent into a ring shape with the contacting ends provided with projections and indentations which fit together to form a complete ring. The ends are held together using an anchor strut which has projecting tabs at both ends. The tabs fit into cooperating slots located in the projections at the ends of the bent strip and at the midpoint of the bent metal strip. The tabs are bent over to locate all parts rigidly in place.

  • Kiln car
    Patent number: 5529488
    Abstract: An improved kiln car comprises a car with a load box with a base that can be separated into parts that can be reconfigured to form a discharge and then rotated to reform the base but with the load-bearing side on the underside so as to present a clean side to the next load of green items to be fired and to counter the cumulative effects of distortion as the load bearing base makes repeated passes through the kiln.

  • Non-welded support plate member
    Patent number: 5510061
    Abstract: Channel beams of a particularly advantageous design are provided. These can be assembled to form a non-welded support plate in a confined environment having any desired configuration and later disassembled and reused elsewhere. The support plates are designed to support tower packing materials whether of the structured or dumped kind.

  • Securing packing elements
    Patent number: 5510170
    Abstract: Corrugated tower packings which are easier to fabricate from individual corrugated elements having parallel rows of ridges and valleys wherein the elements are provided with extension tabs along the ridges of at least a first surface of such elements to provide a location at which the tabs can be spot welded to a contacting element to provide a rigid structure.

  • Titania-based catalyst carriers
    Patent number: 5484757
    Abstract: Advantageous titania based catalyst carriers for use in applications requiring a balance of surface area and crush strength can be obtained by using as the starting material a titania hydrate pulp with a surface area above about 200 m.sup.2 /g and an LOI of from about 15% to about 40% by weight.

  • Catalyst carrier
    Patent number: 5266548
    Abstract: Porous carrier materials comprising at least 90% by weight of at least 95% pure alpha alumina are very effective as supports for catalysts treating engine exhausts and are significantly better able to withstand extreme conditions than conventional supports.
