  • Door sensing fuse block with side extending rotary disconnect
    Patent number: 6724291
    Abstract: A fuse block for cabinet mounting provides a shaft that may exit a side of the cabinet to be received by a handle mounted on that side. A finger attached to the inner cabinet door provides for an interlock by engaging with a bolt communicating with the shaft preventing inadvertent opening of the cabinet when the fuse block is connected to power and/or connecting the fuse block to power when the cabinet door is open.

  • Composite for filtering hot gas and method of its manufacture
    Patent number: 5071457
    Abstract: A composite filter element for filtering hot gasses is made up of a porous ceramic core to which a porous ceramic, thin outer layer is integrally bonded. The outer layer has a mean pore size which is at least several times smaller than the mean pore size of the substrate and the substrate is at least several times thicker than is the outer layer. The outer layer and the substrate are preferably formed of the same material or of two different materials having essentially the same coefficient of thermal expansion.

  • Method and apparatus for particle separation
    Patent number: 4741841
    Abstract: Particulates which are less than and greater than a predetermined size and are entrained in a fluid are separated according to their respective sizes by passing the fluid and entrained particulates through a porous, crossflow separator element while continuously vibrating the separator element to prevent buildup of particulates on the upstream side of the separator element.

  • Filter element and method of use
    Patent number: 4247394
    Abstract: A filter element utilizes a perforate inner filter tube sock tightly fitted within an outer perforate support tube sock, the two socks being sealably mounted at their open ends to a tube sheet with the support tube held in tension by the pressure differential across the filter tube during operation of the associated filter.

  • Distributor collector assembly
    Patent number: 4094790
    Abstract: An axially rigid, tubular grid is fitted over an apertured conduit; a fine mesh flexible tube is fitted over the grid with the ends of the tube being folded back over annular sealing gaskets disposed at the ends of the grid; and an end cap is threaded onto the distal end of the conduit to compress the gaskets against the conduit at the ends of the grid to seal the ends of the flexible tube to the conduit.
