20080250780 | Aquatic sink for carbon dioxide emissions with biomass fuel production - Carbon dioxide emissions from a hydrocarbon combustor are discharged into a large aquatic body, which acts as a CO | 10-16-2008 |
20080250791 | Electric power station with CO2 sink and production of industrial chemicals - A system and method for generating electricity at a desert site comprises a power plant having a combustion unit that burns aquatic bio fuel to produce electricity for distribution to a grid and an exhaust stream containing carbon dioxide. An exhaust gas distribution system connects the combustion unit with a large inland basin of salt water at the site, for growing a plant bloom in the basin. The bloom is harvested and converted into the bio fuel that is burned in the combustion unit. The basin is continually supplied by a source of salt water selected from an ocean, sea, bay, or cove. A salt extraction plant is on site for producing sea salt from water drawn from the basin, and a chemical production plant is on site for converting the extracted sea salt into at least one of sodium hydroxide and chlorine gas using some of the generated electricity. | 10-16-2008 |
20080318163 | Water spray development of planographic plates - Excellent development of planographic printing plates can be achieved by exposing an imaged, negative working, photopolymerizable coating to a high pressure stream of essentially untreated tap water, whereby the water completely removes only the less cohesive and adhesive (e.g., partially polymerized) regions to the substrate, thereby directly producing a printing plate having an image pattern of highly cohesive and adhesive, oleophilic regions of the coating and hydrophilic regions of the substrate. The coating removal mechanism appears to be due entirely to ablation. The high pressure stream is preferably delivered to the plate through at least one nozzle having a discharge pressure greater than about 200 psi. Each nozzle preferably has a spray pattern that impinges the plate over a substantially rectangular region of the plate, and the nozzle and plate translate relative to each other. The nozzle can reciprocate across the width of a longitudinally transported plate, thereby contacting successive regions of the plate in a rastering fashion. | 12-25-2008 |
20080318164 | Heated water spray processor - Excellent development of planographic printing plates can be achieved by exposing an imaged, negative working, photopolymerizable coating to a high pressure stream of essentially heated but otherwise untreated tap water, whereby the water completely removes only the less cohesive and adhesive (e.g., partially polymerized) regions to the substrate, thereby directly producing a printing plate having an image pattern of highly cohesive and adhesive, oleophilic regions of the coating and hydrophilic regions of the substrate. The coating removal mechanism appears to be due entirely to ablation. The process variables of spray pressure, spray volumetric flow rate, and water temperature can be traded off to achieve one or more targets for plate quality, energy conservation, production rate, and equipment availability. | 12-25-2008 |
20090095183 | Printing plates with permanent resin laminated interleaf - In a lithographic printing plate and method of manufacture, an interleaf is permanently integrated to the bottom surface of the plate substrate. A thin, flexible, water and solvent insoluble film is adhered to and covers the bottom surface of the coated and cured sheet before the sheet is cut into plates. The interleaf has a lesser thickness than the thickness of the substrate. A preferred method comprises the steps of selecting a wound coil of aluminum sheet, unwinding the coil and advancing the sheet through a coating station at which a liquid coating of radiation imageable material is applied to the top surface of the sheet, curing the material to form a cured coating adhered to the top surface of the sheet, laminating a polymeric film to the bottom surface of the sheet, and advancing the laminated sheet to a cutting device where individual plates are cut from the sheet. | 04-16-2009 |

The plate comprises a substrate carrying an imaged coating and nonimage areas. The respective cohesive and adhesive properties of the nonimage and image areas to the applied ink, substrate, blanket roll and printable medium, and the ink to the roll are such that the blanket roll pulls the ink from the plate and the ink pulls the nonimage areas from the substrate as undissolved particles that are transferred by the blanket with the ink to the printable media. | 05-10-2012 |
20120186473 | Lithographic Printing Plate Amenable To Post-Heating - A negative working, radiation imageable plate having an oleophilic resin coating that reacts to radiation by cross linking and is non-ionically adhered to a hydrophilic substrate. The plate is amenable to steps that include imagewise radiation exposing the coating to produce an imaged plate having partially reacted image areas including unreacted coating material, and completely unreacted nonimage areas; developing the plate by removing only the unreacted, nonimage areas from the substrate while retaining unreacted material in the image areas; and blanket exposing the developed plate with a source of energy which further reacts the retained unreacted material in the image areas. A plate with a coating containing resin particles can be imaged to produce initial cross-linking, then mechanically developed. Hardening of the imaged areas is completed with a relatively intense post-heating at 160 deg. C., which further cross links the monomer and fuses the resin particles. | 07-26-2012 |

20130340365 | Tetrahedral Tube Reinforcement of Concrete - A weight reduced and strength enhanced concrete structure in which at least one tubular reinforcing core is embedded in a solid concrete matrix. Each core is a chain of integrally interconnected hollow tetrahedra. Each tetrahedra has triangular faces connected at common edges and vertices. The planar faces of adjacent tetrahedra are spaced from each other, and concrete fills the spaces. The cores are suspended within the concrete and self-anchored, without anchors at the exterior surface of the structure. With the embedded cores the concrete structure becomes more resistant to compressive, tensile, and bending loads. For even greater strength of the structure, the cores can be tensioned and thereby pre-stress the concrete. Impact or other loads are distributed substantially isotropically, thereby reducing local stresses. These advantages can be achieved with cores that are lighter than the concrete material they displace or rebar they replace. | 12-26-2013 |
20140060305 | Armor with Tetrahedral Core - An explosion resistant armor for use on a military vehicle and method of manufacture. The explosion resistant comprises a plurality of tubular core members rigidly secured together in adjacent rank formation. The rigidly secured core members are sandwiched between upper and lower plates, such that each core member is in the form of a chain of integrally interconnected hollow tetrahedrons. | 03-06-2014 |
20150053103 | Method of Developing a Lithographic Printing Plate Including Post Treatment - A method for producing a lithographic plate from a negative working, radiation imageable plate having an oleophilic resin coating that reacts to radiation by cross linking and is non-ionically adhered to a hydrophilic substrate. The steps include imagewise radiation exposing the coating to produce an imaged plate having partially reacted image areas at an initial double bond conversion rate including unreacted coating material, and completely unreacted nonimage areas; developing the plate by removing only the unreacted, nonimage areas from the substrate while retaining unreacted material in the image areas; and subjecting the upper surface of the plate to blanket post treatment energy, which further reacts the retained unreacted material in the image areas to increase the initial double bond conversion rate, producing a lithographic printing plate with enhanced durability. | 02-26-2015 |
