Abstract: A clock generator for supplying one or more clock signals to integrated circuits within a processor-based system is disclosed. The clock generator includes one or more PLLs and one or more configuration registers. The clock is supplied power from two different voltage sources, such that, during a standby mode of the system, the configuration registers continue to be powered with the lower of the two voltages while the PLLs are turned off. Upon returning from the standby mode, the clock generator is reinitialized according to a user-defined configuration, since the configuration registers retain data throughout standby mode. Alternatively, the clock generator may be reinitialized to a default state following standby mode, for backwards compatibility with prior art clock generators.

Abstract: A process for the pyrolysis of carbonation materials such as wood which comprises directly or indirectly heating the carbonaceous material with flue gases. When carbonization commences the direct heating is stopped while indirect heating continues until carbonization is complete. There is also described an application for effecting the process.

Abstract: The present invention provides a charcoal producing apparatus comprising a combustion chamber, a heating chamber, first passage means interconnecting the combustion chamber and a discharge flue and second passage means interconnecting the heating chamber with the combustion chamber the second passage means being open to the atmosphere and having means for closing it off from the atmosphere. The invention also provides a method for the production of charcoal.
