Patent EP-1446722-A4 (EP)
Title: User equipment (ue) having a hybrid parallel/serial bus interface
Inventor: GREDONE JOSEPH
IPC: H03M9/00
Filed: 2002-11-18
Abstract: A hybrid serial/parallel bus interface for a user equipment (UE) has a data block demultiplexing device (40). The data block demultiplexing device has an input configured to receive a data block and demultiplexes the data block into a plurality of nibbles. For each nibble, a parallel to serial converter (42) converts the nibble into serial data. A line (44) transfers each nibble's serial data. A serial to parallel converter (46) converts each nibble's serial data to recover that nibble. A data block reconstruction device (48) combines the recovered nibbles into the data block.

Title: Macro-engineering process for all-weather at-sea wind-energy extraction.
Inventor: SCHREMP EDWARD JAY
IPC: F03B13/18
Filed: 1988-06-24
Abstract: A process is disclosed for harvesting energy from wind energy on the high seas in all weather conditions, on a year-around basis. This process depends upon the use of sea-going platforms (2) which themselves achieve stability in the presence of storms at sea, doing so through the selective extraction of wave energy. The selective wave energy extraction takes place in such a way that the prevailing ratio of sea height to swell height affecting a typical sea-going platform (2) is reduced to a small fraction of the ratio of sea height to swell height which prevails at a distance from the platform (2).
Patent EP-0394316-A4 (EP)
Title: Process for beneficiating particulate solids
IPC: C01G49/08
Filed: 1988-11-30
Abstract: Fine particle coal is beneficiated in specially designed dense medium cyclones to improve particle acceleration and enhance separation efficiency. Raw coal feed is first sized to remove fine coal particles. The coarse fraction is then separated into clean coal, middlings, and refuse. Middlings are comminuted for beneficiation with the fine fraction. The fine fraction is deslimed in a countercurrent cyclone circuit and then separated as multiple fractions of different size specifications in dense medium cyclones. The dense medium contains ultra-fine magnetite particles of a narrow size distribution which aid separation and improves magnetite recovery. Magnetite is recovered from each separated fraction independently, with non-magnetic effluent water from one fraction diluting feed to a smaller-size fraction, and improving both overall coal and magnetite recovery. Magnetite recovery is in specially designed recovery units, based on particle size, with final separation in a rougher-cleaner-scavenger circuit of magnetic drum separators incorporating a high strength rare earth magnet.
