Process for adjusting the moisture content of tobacco

A process for reordering tobacco, which results in no significant decrease in equilibrium tobacco CV or significant tobacco degradation, is provided. Tobacco to be reordered is contacted with an air stream having a relative humidity near the equilibrium conditions of the tobacco. As the OV content of the tobacco increases, the relative humidity of the air stream contacting the tobacco is increased to affect reordering of the tobacco. Also provided is a process for drying tobacco, which results in no significant change in equilibrium tobacco CV or significant tobacco degradation. Tobacco to be dried is contacted with an air stream having a relative humidity near or below the equilibrium conditions of the tobacco. As the OV content of the tobacco decreases, the relative humidity of the air stream contacting the tobacco is decreased to affect drying of the tobacco. It has been found that tobacco can be reordered or dried successfully in a continuous manner using a self-stacking spiral conveyor.

Initial program load (ipl) based on an object abstraction for a data processing system

Abstract of the Disclosure In the system and method of this invention, a data processing system is dynamically configured during IPL (initial program load) time. All of the entities of the data processing system, including physical and logical devices, are represented as objects in an object oriented database. The object oriented database also contains an object class of rules which define the sequence of events that are needed in order to configure the system. A number of methods are defined to perform specific functional operations on the objects. A configuration manager invokes the appropriate method to perform operations on the objects according to the rules. The objects are dynamically defined, configured, started, stopped, unconfigured, and undefined independent of whether the objects represent physical or logical entities. In this way, both physical and logical entities are configured in a consistent and similar fashion.

Anti-decubitus mattress pad

A mattress pad (1) is multi-layered and includes a cover or casing (5, 7) containing interior strata of a plastic film (17) layer atop a fluid bladder layer (19) supported on an underlying layer of foam (21).

The unique identifier of the electronic tag and the unique biometric identifier is then submitted to a multi-factor authentication module, which compares it to authentication information associated with the user. If the submitted unique identifiers match the user's authentication information, then the user is authenticated.
