Granted: 2004-12-07
Abstract: At the transmitter side, carrier waves are modulated according to an input signal for producing relevant signal points in a signal apace diagram. The input signal is divided into, two, first and second, data streams. The signal points are divided into signal point groups to which data of the first data stream are assigned. Also, data of the second data stream are assigned to the signal points of each signal point group. A difference in the transmission error rate between first and second data streams is developed by shifting the signal points to other positions in the space diagram. At the receiver side, the first and/or second data streams can be reconstructed from a received signal. In TV broadcast service, a TV signal is divided by a transmitter into, low and high, frequency band components which are designated as a first and a second data stream respectively.      Upon receiving the TV signal, a receiver can reproduce only the low frequency band component or both the low and high frequency band components, depending on its capability.

Title: An apparatus and process for pre-hydrolysis of biomass
Inventor: GARCIA PINATTI DALTRO
IPC: C13B10/14
Filed: 2000-06-23
Granted: 2007-10-30
Abstract: This invention refers to an apparatus for the processing of pre-hydrolysis o f biomass, particularly a reactor of the failsafe type, either mobile or not, which may be manufactured of microbonded carbon steel and coated with specia l materials (refractory metals, superalloys, stainless materials, plastics, etc.). The insertion of vacuum between the shell of the reactor and its coating prevents its implosion and permits the detection of leakage with helium gas. The resistance to corrosion of the refractory metals enables carrying out of pre-hydrolysis and mineral digestion. In the process of this invention, biomass is compacted at 300 kg/m3 by a helical feeder, degased, flooded, heated, stirred, pre-hydrolyzed, the sugar being recovered at a fir st washing within the reactor with values higher than 90 %. The low liquid/soli d ratio = 2 enables one to achieve sugar content of 10 bricks in the pre- hydrolysate and a consumption of 6 % of the energy contained in the processe d biomass. The pre-hydrolysate is constituted by solutions of xylose and other s and is intended for the production of furfural, alcohol and xylitol. The control of the process enables one to produce cellulignin with a high specif ic surface, 2 m2/g (measured by BET), compared with the value of 0.4 m2/g of no n- hydrolyzed biomass,maintain crystallinity of the cellulose fibers, aiming at grinding it into fine particles (f<)250 mm), globulizing the lignin, expo sing the cellulose to attacks by microorganisms from cud of ruminants, fungi, bacteria or enzymes in microbiological or enzymatic fermentation. The catalytic combustion due to the large specific surface results in a new fuel for boilers, combustors in general and MHD when produced with filtered water , and for gas turbines when produced with deionized water.

Abstract: An isolated phase bus duct joint assembly couples together first and second phase bus duct sections where each section has an interior bus conductor surrounded by an outer housing. The joint assembly couples end portions of the interior bus conductor and has first and second conductor coupling portions each extending from the end portion of one of the interior bus conductors. Each coupling portion has a reduced outside dimension relative to the interior bus conductors. The joint assembly has a plurality of movable electrical contact fingers mounted by spring loaded adjustment fasteners around the outside surface of the first conductor coupling portion. Each of the fingers extends beyond the first conductor coupling portion for engagement with the outside surface of the second conductor coupling portion. The spring loaded adjustment fastener has a threaded stem passing through the finger and the first inner conductor coupling portion. The stem has an adjustable head engaging an outer surface of the finger and a compression spring mounted over the stem to engage the inside surface of the first inner conductor coupling portion. The heads and stems are adjusted relative the compression spring to urge the fingers into locking engagement with the first and second coupling portions. This advantageously results in no substantial increase in electrical clearance required between the inner bus conductors and the outer housing. Further, the heads may be backed off to provide for de-coupling or separation of the joint.

Abstract: A method for preparing a decomposition catalyst for an organic halide, which comprises reacting a salt of Pt and/or Pd, an alkoxide derivative of Ti and an amino acid as an organic binding compound in a solvent, to synthesize an organic metal-containing precursor containing Ti and Pt and/or Pd in a molecule thereof, and heating the precursor to prepare the decomposition catalyst comprising fine particles of Pt and/or Pd dispersed in TiO2; and a method for manufacturing a filter for use in decomposing an organic halide, wherein the above decomposition catalyst is carried on the surface of the clean side of a ceramic filter. The method allows the uniform dispersion of fine particles of Pt and/or Pd in TiO2 particles, which results in the increase of active sites of the resultant catalyst, leading to a higher activity of the catalyst than that of a conventional catalyst. As a result, the catalyst exhibits excellent decomposition activity even at a temperature lower than 200~C.

Title: Method for manufacturing a filter body
Inventor: KOHRICHT KARL-HEINZ
IPC: B01D39/20
Filed: 2002-04-02
Granted: 2008-02-19
Abstract: The first step of a method for manufacturing polymer-bonded filter bodies is to produce a mixture of a sorptive agent, a liquid, and a polymer. This mixture is then pressed into a filter body by being placed in a compression mold and simultaneously applying a hot gas to it. The evaporation temperature of the liquid is lower than the melting temperature of the polymer while the temperature of the hot gas flowing through the mixture exceeds the evaporation temperature of the liquid. This inexpensive method can provide homogeneously structured high-performance filter bodies.
