Gerald V. Storch - Bridgewater NJ

Assignee:

Exxon Research and Engineering Company - Florham Park NJ

International Classification:

G01F 174

US Classification:

7386104

Abstract:

A method for measuring the mass flow rate of liquid flow exiting a two phase (gas/liquid) feed nozzle. The method includes determining the Power Spectral Density from the output of an accelerometer in close proximity to the restriction orifice controlling the gas flow, or determining the Power Spectral Density from the output of a pressure transducer in contact with the gas flow on the down stream side of the restriction orifice. The liquid flow can then be obtained from a predetermined correlation between the RMS Vibrational Signal and the mass or liquid flow rate.

Assignee:

Discovery Zone, Inc. - Chicago IL

International Classification:

B08B 104

US Classification:

134 254

Abstract:

An apparatus and method for washing balls in a fluid is disclosed which includes a container for storing soiled balls and a wash unit having an elongated cylindrical housing suitable for containing the fluid and having a lower end adapted for receiving balls and an upper end adapted for discharging balls. The container serially dispenses balls via a transfer chute to the lower end of the housing. The transfer chute includes apparatus for separating regular and irregular balls. Inside the housing, balls are conveyed from the lower end to the upper end by a screw conveyor system which agitates and scrubs the balls. The screw conveyer system includes an first screw conveyor located near the lower end, and a second screw conveyor located near the upper end. The first and second screw conveyors are spaced to form a conveyor free wash cell. Balls are discharged at the housing's upper end to a ramp having a plurality of overlapping flights, where the balls are rinsed.

International Classification:

B01J 8/24
C10G 11/18
B01J 38/30

Abstract:

A catalyst regenerator for combusting carbonaceous deposits from a catalyst comprising a first chamber which comprises a catalyst inlet for feeding spent catalyst with carbonaceous deposits to said first chamber, a supplemental fuel gas distributor, and a distributor for an oxygen containing gas for distributing oxygen containing gas into said first chamber to contact said spent catalyst and combust carbonaceous deposits and supplemental fuel which further deactivates the spent catalyst and generates flue gas; a riser section extending from said first chamber for transporting the spent catalyst and the flue gas, the riser section comprising an outer wall, at least one slot in the outer wall, and a riser termination device which comprises a substantially internally flat cover plate, at least one arm extending from the cover plate, wherein the arm extends about the slot from the outer wall, the arm comprising an outer shell that encloses the arm and wherein no internal portion of the cover plate extends above an upper surface of the outer shell of the at least one arm is provided. Further provided is a riser termination device.
