  • Flow disrupter for dryers
    Patent number: 6438866
    Abstract: The present invention provides a flow disrupter within the flow path of a slurry comprising a desired particulate matter and a transport fluid so as to impart a force angularly disposed to an otherwise obtained direction of travel, thereby preventing the formation of a sheet of aggregated particulates against the screen surface. In a method in accord with the present invention a force is imparted to the desired particulate matter in an angular direction to the direction of travel.

  • Stepped wear indicator for a radial compressor
    Patent number: 5879146
    Abstract: The invention includes a wear indicator for a radially extensible vane compressor. The indicator is an elongate member having two longitudinal sections with a step inbetween. The step catches on a mating step formed in the compressor rotor when it is good and does not catch on the mating step when it is bad (i.e., worn). A repair person can test the wear of the indicator merely by attempting to withdraw the indicator. If it is removed it is worn, and if it is not removable, it is acceptable.

  • Process for the partial dehydration of a crude water-wet organic stream of the monohydroperoxide of p-diisopropylbenzene
    Patent number: 5283370
    Abstract: A process for the partial dehydration and partial purification of a crude water-wet organic stream of the monohydroperoxide of p-diisopropylbenzene is disclosed. This crude stream of monohydroperoxide contains at least 2 wt % water and is partially dehydrated by contacting the stream with a non-reactive inorganic salt to remove a portion of the water into a concentrated brine of the inorganic salt followed by separation of the concentrated brine and the product. The crude water-wet organic stream of the monohydroperoxide is optionally filtered and coalesced prior to contacting the nonreactive inorganic salt.
