Appl. No.:

29/171580

Inventors:

Stephen J. Mohary - Pennington NJ, US
Stephen R. Perry - Blue Bell PA, US

Assignee:

Johnson & Johnson Consumer Companies, Inc. - Skillman NJ

International Classification:

US Classification:

D 9571, D9574

US Patent:

20030154306, Aug 14, 2003

Filed:

Jan 21, 2003

Appl. No.:

10/347374

Inventors:

Stephen Perry - Plymouth MA, US

International Classification:

G06F015/16
G06F015/173

US Classification:

709/245000, 709/239000

Abstract:

A system and method for network address translation that enables an inbound connection from the public network to a privately addressed host residing on a private network. The stated invention functions as a reverse proxy mechanism assigning a dynamic port number to uniquely identify each inbound connection from the public network to a host on the private network. The defined proxy device uses regular and reverse mapping and employs use of the passive command to notify the client on the public network of the said unique port number assigned for the inbound connection. When the session is completed, the port is returned to the pool to be reassigned as needed.

International Classification:

C10G 4308

US Classification:

208 33

Abstract:

An improved DILCHILL* dewaxing process wherein waxy lubricating oil stocks are solvent dewaxed by contacting them with successive increments of cold dewaxing solvent at a plurality of points along the height of a vertical tower divided into a plurality of stages while agitating the oilsolvent mixture in each stage to provide substantially instantaneous mixing of the waxy oil and solvent thereby precipitating wax from the oil while avoiding the well known shock chilling effect. The improvement resides in adjusting the cold solvent addition to each stage in a manner so as to modify the temperature profile along the tower to ensure that the temperature drop per stage in the initial stages in which wax precipitation occurs is greater than the temperature drop per stage in the final or later stages in which wax precipitation occurs. * DILCHILL is a registered Service Mark of Exxon Research and Engineering Company.

International Classification:

C10G 4314

US Classification:

208 33

Abstract:

Ketone dewaxing solvent is separated and recovered from dewaxed oil and a wax slurry through the use of flash vaporization or distillation followed by steam stripping. Water is removed from the recovered solvent through the use of a combination of a decanting drum to form a solvent phase and a water phase, a deketonizer tower which strips solvent from the water phase, and a simple distillation tower which functions as a solvent dehydrator. It has been found that feeding a portion of the overhead vapors from the flash vaporization step directly to the bottom of the dehydrator provides enough heat to eliminate the need for a reboiler on the dehydrator tower.
