US Patent:

48738760, Oct 17, 1989

Filed:

Nov 7, 1988

Appl. No.:

7/267984

Inventors:

Michael Sheridan - Old Bridge NJ
Kenneth Jaffe - Boulder CO

Assignee:

Ethylene Corp. - Murray Hill NJ

International Classification:

G01N 120

US Classification:

7386386

Abstract:

A chemical process sampler for use in monitoring the progress of chemical processing particularly suited for the handling of toxic, volatile, or otherwise dangerous substances. The sampler is characterized in the provision of multi-position valve structure for returning a contained sample to the processing vessel after use, thereby eliminating the need for separate disposal.

US Patent:

45781702, Mar 25, 1986

Filed:

Apr 5, 1985

Appl. No.:

6/720495

Inventors:

Michael Sheridan - Old Bridge NJ

Assignee:

Ethylene Corp. - Murray Hill NJ

International Classification:

G01N 2730

US Classification:

204400

Abstract:

A rapidly demountable structure for supporting electronic probes within a reactor vessel at the inner end of a dip tube element. The structure includes a fixed dip tube element which is permanently positioned in a recess at the inner end of the dip tube, and a probe supporting element selectively engaged with the dip tube element through a bayonet type interconnection. A damaged probe is replaced by first disconnecting the probe supporting element from the dip tube element, and disassembling the probe supporting element to permit removal and replacement of the probe. Means is provided to seal the opening to the reactor vessel during the period in which the probe supporting element is in disengaged condition thus affording safety to service personnel during replacement of the damaged probe.

Appl. No.:

7/151169

Inventors:

Michael Sheridan - Old Bridge NJ
Kenneth Jaffe - Boulder CO

Assignee:

Ethylene Corp. - Murray Hill NJ

International Classification:

G01N 110

US Classification:

7386463

Abstract:

An improved sight glass for use with sampling systems employed for testing the content of chemical reaction vessels. In addition to incorporating a check valve for preventing contamination of a vacuum source, the device incorporates provision for entrapping and draining sampled fluids in the event of leakage or fracture of the glass components thereof. This is accomplished by providing an inner transparent glass tube, the inner surface of which is chemically inert, and an outer concentric tube of synthetic resinous material which surrounds the inner tube and is less subject to breakage. The cylindrical interstice between the inner and outer tubes forms a drain for retaining leakage caused by fracture of the inner tube. A floating valve cooperates with a valve seat positioned longitudinally medially of the inner and outer tubes.

Appl. No.:

7/367781

Inventors:

Michael Sheridan - Old Bridge NJ

Assignee:

Ethylene Corp. - Murray Hill NJ

International Classification:

B65D 4504

US Classification:

215330

Abstract:

A sample collection container for use in receiving samples for analysis and testing of fluids from a sample valve forming part of a chemical process line. The container includes a closure element which selectively engages the sample valve during collection and provides means for protecting the user handling the sample container after disengagement from the sample valve from spillage. The container closure is selectively engageable by a cap element when disengaged from the sample valve, the cap element having an orificed end wall which may be selectively closed or provided with means supporting a penetrable membrane for hypodermic extraction of fluid.

Filed:

Mar 6, 1987

Appl. No.:

7/023114

Inventors:

Michael Sheridan - Old Bridge NJ

Assignee:

Ethylene Corp. - Murray Hill NJ

International Classification:

G01N 114
G01N 2756

US Classification:

422 49

Abstract:

A device capable of being mounted in a small opening in a reactor vessel, after having been inserted through a manway, which permits the continuous sampling of the contents of the reactor during a reaction, and continuous monitoring of the pH factor or other characteristic of interest. Electrical probe replacement is possible without disconnecting the device from the reactor vessel, and requires only a minimum of down time.

International Classification:

G08B 2100

US Classification:

3406935

Abstract:

A communication appliance with a desktop unit and a secondary unit. The desktop unit includes an outer casing, bottom feet, openings in the outer casing for control elements, a plurality of heat-producing electronic components and at least one speaker. The bottom feet extend from a bottom of the outer casing and support the outer casing on a surface such that the bottom of the outer casing is spaced from the surface. The control elements are used for operating the communication appliance. The outer casing includes a plurality of cooling slots for cooling electronic components found in the interior of the communication appliance so that a fan or other external device is not needed.
