  • Patent number: 4066801
    Abstract: A processing system which can provide a continuous assembly-line procedure for placing a catalytic coating on ceramic honeycomb type members embodies the use of a plurality of pressure tight chambers such that each ceramic member can be vacuum treated and then rapidly coated, as well as pressure treated and air blown to effect rapid coating fluid removal and partial drying. After each coating operation, there is controlled drying and high temperature curing. Also, in a preferred controlled system, there is a weighing of each element before and after each coating step to determine an amount of coating retained for comparison with a predetermined standard.
    Type: Grant
    Filed: December 15, 1975
    Date of Patent: January 3, 1978
    Assignee: Universal Oil Products Company

  • Patent number: 4039482
    Abstract: A liftable housing form of pressure tight treating chamber is especially adapted to providing multiple stage treatments to catalyst support members, such as honeycomb-type elements, in order to place a catalytic coating on all of the interior surfaces of the multiple passageways through the elements. Power operated lifting of an open-bottomed housing permits the placement of members on sharp edged pin support means in the interior of the chamber such that passageways will not be blocked while the element is being subjected to vacuum, liquid coating, and air blowing stages.
