Granted: 2008-04-15
Abstract: A method for removal of organic contaminants from solid particulate soil contaminated with the organic contaminants. The method comprises forming an aqueous slurry of a mixture of a hydrophobic adsorbent selected from foamed synthetic materials or natural materials which entrap gas, with the soil in the presence of water.  The adsorbent has a density less than water. The slurry is mixed for a period of time, and a gravity separation of the adsorbent from the aqueous admixture thus obtained is effected.

Title: Transmission and reception of television programs
Inventor: TEN KATE WARNER RUDOLPH THEOPHILE
IPC: H04H20/00
Filed: 1998-04-20
Granted: 2012-02-07
Abstract: A television transmitter transmits addditional information in the form of Web pages along with the television signal. The transmission further includes triggers (71) for selectively invoking said Web pages in synchronism with the program. The triggers include (or refer to) a perceptible signal, e.g. a pictogram or an audible beep. In response to receiving a trigger, a receiver reproduces said perceptible signal without substantially disturbing the television screen. The user is thus timely alerted about additional information related to the television program when viewing it. Then, he may or may not invoke the relevant Web page at his own discretion. To inform the public in advance of the triggers that will be broadcast and to provide easy access to the Web pages at an earlier or later stage, the transmission further includes a table of contents (80) identifying the triggers that are being transmitted during the program. The table of contents itself may be invoked by a trigger (70).

Granted: 2007-10-02
Abstract: The invention relates to a cartridge thermostatic mixing valve, secured by a ring within a standard tap body, divided into a first upper subassembly made up of the members for transmitting the temperature adjustment (1-10) and a second lower subassembly including the members for transmitting the flow rate adjustment and the valve group which carries out said adjustment (11, 12, 17-24). The first subassembly is removable in an assembled state from the cartridge without acting on the second subassembly which is retained in its position by the ring, so as to remove the member of the thermostatic device for the cleaning of the mixing chamber without requiring to cut off the water upstream from the tap. The cartridge has a simplified structure with a small number of pieces, with the temperature and flow rate controls which are completely independent of each other and consist of a temperature adjustment knob and a flow rate adjustment lever which is rotatable between the knob and the tap body.

Title: Device for recovering and separating impurities from the cooling fluid of a conditioning system
Inventor: RENDERS MARIE JOSEPH
IPC: F25B43/00
Filed: 1998-03-02
Granted: 2008-05-27
Abstract: A device for recovering and separating impurities from untreated contaminated cooling fluid of a conditioning system comprises a container having a base and an upper closure which has an inlet for untreated contaminated cooling fluid and a first outlet for vaporized cooling fluid, the base having a second outlet for impurities. A heating means inside the container heats untreated contaminated cooling fluid to a selected temperature above a vaporization point of vaporized uncontaminated cooling fluid, and a first duct system draws vaporized cooling fluid from the first outlet and feeds it to an enclosure having a heat conductive wall, and a second duct system transfers treated cooling fluid from the heating means to an external collection tank. The continuous contact of the fluid with a heat exchange surface during treatment maximizes coolant removal and thus minimizes coolant residue in the extracted impurities.

Granted: 2009-05-12
Abstract: Provided are novel DT- and ETA-based immunotoxins and a method of treating a n immune system disorder not involving T cell proliferation, comprising administering to the animal an immunotoxin comprising a mutant diphtheria toxin moiety linked to an antibody moiety which routes by the anti-CD3 pathway, or derivatives thereof under conditions such that the disorder is treated. Thus, the present method can treat graft-versus-host disease. Also provided is a method of inhibiting a rejection response by inducing immune tolerance in a recipient to a foreign mammalian donor tissue or cells, comprising the steps of: a) exposing the recipient to an immunotoxin so as to reduce the recipients' peripheral blood T-cell lymphocyte population by a t least 80%, wherein the immunotoxin is anti-CD3 antibody linked to a diphtheria protein toxin, wherein the protein has a binding site mutation; and b) transplanting the donor cells into the recipient, whereby a rejection response by the recipient to the donor organ cell is inhibited, and the host is tolerized to the donor cell.

Granted: 2007-01-09
Abstract: The invention concerns measurement of sucrose series oligosaccharides, particularly sucrose, raffinose, and stachyose, and the dehydrin group proteins, in conifer somatic embryos as a measure of their biochemical maturity and readiness to germinate. The information gained is useful for evaluation of the effectiveness of the culture media, particularly that used for the development of the cotyledonary embryo stage. Somatic embryos having elevated levels of the oligosaccharides have been shown to have improved germination, especially those in the genus Pinus. The invention is also directed to conifer somatic embryos having elevated levels of sucrose series oligosaccharides and dehydrin group proteins.

Inventor: VELLOSO ANTONIO AUGUSTO M
IPC: C01B21/40
Filed: 1999-12-21
Granted: 2003-05-13
Abstract: A process is described for producing nitric acid involving oxidizing ammonia gas to form dinitrogen tetroxide gas, reacting the dinitrogen tetroxide with water in an absorption zone to form aqueous nitric acid and nitric oxide gas, removing a nitric acid/nitric oxide stream from the absorption zone and feeding the stream into a nitric acid bleaching zone, removing impurities from the nitric acid in the bleaching zone to form nitric acid product and adding supplemental oxygen gas to one or more of the reaction streams to increase nitric acid production and or strength. The improvement involves injecting the supplemental oxygen into a nitric acid-containing process stream to form a gas bubble/liquid mixture in the stream, the mixture forming a fine dispersion of gas bubbles having diameters of less than about 0.1 mm. According to the invention, increased interfacial surface is created between the gas bubbles and the liquid mixture to facilitate removal of impurities from the liquid phase and shifting of the reaction.

Abstract: A flat fold hinge assembly for implement frame sections that fold substantially greater than 90 degrees includes a modular hinge having first and second hinge portions that bolt solidly to the frame sections. A folding cylinder is protectively cradled between the sides of a cast mounting bracket closely adjacent the frame tube. Floating links are connected to the rod end of the cylinder generally below the main pivot which is offset above the frame tube a distance substantially less than most previously available hinge structures for compact storage of the wing frame close to the inner frame. The design, preferably utilizing four cast components, is more compact than previous designs so the frame sections fold more compactly. The simple mounting arrangement provides versatility in locating the hinge assembly to accommodate a wide variety implement configurations and implement attachments. The hinge structure acts to reinforce the tubular frame construction and distribute heavy loads transferred from implement attachments and tools. A  mounting area on the hinge facilitates connection of additional hardware such as a wing support tube truss.
