Abstract: A method for performing a file transfer comprises receiving a request for data where the data is to be compressed. A checkpoint is established, where the checkpoint occurs before the end of the transmission of the requested data. Also, a compression requirement is established for the requested data. The operations of extracting a segment of the data to be communicated, processing the extracted segment according to the compression requirement, and communicating the processed segment across the network are performed until the checkpoint is reached. Once the established checkpoint is reached, a checkpoint routine is performed by determining whether a desired level of performance in compression is achieved in communicating the processed segments. If the desired level of performance is achieved, each additional segment is processed based upon the compression requirement.

Abstract: Method for making artificial tobacco. Comprises preparing a homogenous composition from finely divided plant material and additives, this composition having a moisture content of from about 20 to 50 percent by weight, forming said composition into strand sections and rolling down said strand sections between squeeze rollers, operating at different relative speeds of rotation. An apparatus for performing such method is also disclosed.

Abstract: To produce artificial tobacco from a moist paste moist paste is predried to a 15 to 25% by weight liquid content by pressing out liquid and then shaped and hardened by final drying to convert it into artificial tobacco.

Abstract: For the production of artificial tobacco from pulverized plant parts, liquid and additives, the liquid is continuously forced, simultaneously with but separate from the powder, into a grinding chamber from which paste is continuously removed to be shaped and dried.BACKGROUND OF THE DISCLOSUREThe invention relates to a continuous process for the production of a paste with additives which can be formed into a smokable material, in which process a liquid and pulverized plant parts are introduced into one end of a grinding chamber, stirred and ground by grinding tools within the grinding chamber, and removed at the other end of the grinding chamber as a sieved paste.In processes of this type, the plant parts are ground to their ultimate fineness in a wet state by treating them as carefully as possible in order to avoid a tarry smoke taste.

Abstract: An extruder nozzle for an apparatus for producing tobacco fiber from a paste, pulp, mash or slurry of comminuted botanics, which may or may not contain tobacco, binders, plasticizers and organic and inorganic salts, comprises a nozzle surface formed with a multiplicity of orifices through which strands of the dryable composition are extruded. Distributed among the orifices are openings for a compressed gas, e.g. compressed air, which passes along the fibers in the direction of extrusion thereof and hence applies an entraining force to the strands tending to break them off into fibers.
