Title: High frequency energy application to petroleum feed processing
Inventor: BURKITBAEV SERIK M
IPC: C10G15/08
Filed: 2001-10-18
Abstract: The present invention provides a method and apparatus for maintaining the active life of a catalyst (10) in organic feed (22) processing by applying a series of electromagnetic radiation pulses (30) to the catalyst in a reactor (24). The pulsing of the catalyst selectively heats and cools the catalyst and can regulate the relative internal pressure of the catalyst particles to stimulate the acceleration of oil macromolecules mass-exchange through the catalyst pores and surface. This allows for the removal of cracked oil molecules from the particles. The application of electromagnetic pulses also regulates the activity of the catalyst. The electromagnetic radiation reduces the formation of coke on the catalyst and increases the life of the catalyst in the reactor. Further, the present invention provides a method and apparatus for removing water and salt from an organic feed. Water and salt is removed by applying a series of electromagnetic radiation pulses to the organic feed.

Title: Packet encrypton system and method
Inventor: DAVIS STEPHEN J
IPC: H04L29/08
Filed: 2001-12-21
Abstract: A processor has an input port for receiving packets of data to be processed for encryption. A master controller acts to analyse the packets and to provide a header including a list of processes to perform on the packet of data and an ordering thereof. The master controller is programmed with process related data relating to the overall processing function of the processor. The header is appended to the packet of data. the packet with the appended header information is stored within a buffer. A buffer controller acts to dtermine for each packet stored within the buffer based on the header within the packet a next processor to process the packet. The controller then provides the packet to the determined processor for processing. The processed packet is returned with some indication that the processing is done. For example, the process may be deleted from the list of processes. The buffer controller repeatedly makes a determination of a next process until there is no next process for a packet at which time it is provided to an output port.
