Electrically heated smoking system having a liquid storage portion

An electrically heated smoking system includes a shell and a replaceable mouthpiece. The shell includes an electric power supply and electric circuitry. The mouthpiece includes a liquid storage portion and a capillary wick having a first end and a second end. The first end of the wick extends into the liquid storage portion for contact with liquid therein. The mouthpiece also includes a heating element for heating the second end of the capillary wick, an air outlet, and an aerosol forming chamber between the second end of the capillary wick and the air outlet. When the shell and mouthpiece are engaged or connected, the heating element is in electrical connection with the power supply via the circuitry, and a flowpath for air is defined from at least one air inlet to the air outlet via the aerosol forming chamber. In use, liquid is transferred from the liquid storage portion towards the heating element by capillary action in the wick. Liquid at the second end of the capillary wick is vaporized by the heating element. The supersaturated vapor created, is mixed and carried in the air flow from the at least one air inlet to the aerosol forming chamber. In the aerosol forming chamber, the vapor condenses to form an aerosol, which is carried towards the air outlet.

Method and apparatus for differential pressure testing of catalytic reactor tubes

A multi-tube differential pressure (Delta P) testing system for testing catalyst filled tubes of tube and shell type catalytic reactors has at least one mobile test unit for movement on the upper tube sheet of a catalytic reactor. An array of test probes is mounted to the mobile test unit and is selectively positionable in sealed gas pressure communicating engagement within the upper ends of selected reactor tubes. A pressure testing gas delivery system is interconnected with the test probes and selectively communicates pressurized gas to the testing tubes at a blow-down pressure or selected test pressure determined by restricted orifices. A differential pressure measurement system measures the back-pressure resulting from application of test pressure to individual reactor tubes and having a computer receiving electronic back-pressure measurement data and producing an electronic and/or visual record correlated with a reactor tube numerical sequence and identifying the resulting back-pressure of each reactor tube of the multi-tube test. The testing system is capable of selectively electronically counting in normal sequence and in inverted sequence to accommodate test unit orientation and incorporates a separate manually positioned testing wand to accommodate tube positions of the reactor that cannot be readily accessed by one or more of the array of test probes.

Apparatus and method for enhancing the protection of media content

An aspect of the current invention involves an apparatus and method for protecting media content from being read and copied by an unauthorized party. In one embodiment of the invention, this is accomplished by storing keys for decrypting encrypted media content on a secure memory device located in proximity to a computer processor. A secure memory device located in proximity to a computer processor allows for decryption keys to be sent to a user of the computer processor in advance of the user receiving an encrypted media content that will be decrypted with the decryption keys. With the secure memory device, the decryption keys can be stored indefinitely without an unauthorized party gaining access to them. Another embodiment of the invention allows for multiple media content providers to store their own decryption keys for their own encrypted media content simultaneously on a secure memory device located with a user's personal computer. A further embodiment of the invention involves using a secure memory device located with a means for displaying media content—such as a monitor or speaker—to allow for secure transfer of decrypted, decompressed media content from a computer processor used to play media content, a stand-alone media content player, or a set-top box media content player to a media content display
