Methods for the manufacture of sheets having a highly inorganically filled organic polymer matrix
Compositions and methods for manufacturing sheets having a highly inorganically filled matrix. Suitable inorganically filled mixtures are prepared by mixing together an organic polymer binder, water, one or more inorganic aggregate materials, fibers, and optional admixtures in the correct proportions in order to form a sheet which has the desired performance criteria. The inorganically filled mixtures are formed into sheets by first extruding the mixtures and the passing the extruded materials between a set of rollers. The rolled sheets are dried in an accelerated manner to form a substantially hardened sheet, such as by heated rollers and / or a drying chamber. The inorganically filled sheets may have properties substantially similar to sheets presently made from traditional materials like paper, cardboard, polystyrene, plastic, or metal. Such sheets can be rolled, pressed, scored, perforated, folded, and glued. They have especial utility in the mass production of containers, particularly food and beverage containers.

Compositions, methods, and systems for manufacturing articles, particularly containers and packaging materials, having a highly inorganically filled matrix. Suitable inorganically filled mixtures are prepared by mixing together an organic polymer binder, water, one or more aggregate materials, fibers, and optional admixtures in the correct proportions in order to form an article which has the desired performance criteria. The inorganically filled mixtures are molded to fashion a portion of the mixture into a form stable shape for the desired article. Once the article has obtained form stability, such as by heating to remove water by evaporation, the article is removed from the mold and allowed to harden to gain strength. The articles may have properties substantially similar to articles presently made from traditional materials like paper, paperboard, polystyrene, plastic, or metal. They have especial utility in the mass production of containers, particularly food and beverage containers.

ActiveUS7357854B1Reduce weightHigh densityStentsPolycrystalline material growthElectrolysisBiocompatibility Testing
The invention is directed to an electropolishing solution for products or devices made from at least in part a cobalt-chromium alloy. The invention is particularly suitable for medical devices or intravascular stents made at least in part of cobalt-chromium. More particularly, the electropolishing process of the invention is particularly suited for use on implantable medical devices, such as stents, due to the biocompatibility of cobalt-chromium alloys. The invention is directed to an improved stent formed from a cobalt-chromium alloy, that possesses an ultrasmooth shiny surface. This invention is also directed to a method of electropolishing such a stent using an acidic electrolytic solution comprising a mixture of 6 parts of about 98% sulfuric acid (H2SO4), 1 part of about 37% hydrochloric acid (HCl) and 1 part by of about 85% concentrated phosphoric acid (H3PO4) to produce an exceptionally smooth surface.

Electrolytic microfinishing of metallic workpieces
The invention is an electrolytic microfinishing process which utilizes a conductive tool as a cathode and a conductive workpiece as an anode both connected to a power supply. Electrolytic fluid is pumped between the tool and workpiece, creating a decomposition of the workpiece surface allowing the surface of the workpiece to be removed or wiped away by the interaction of the flowing electrolyte and rotation of the tool without generating any heat at a rate significantly faster than any other known machining process. The tool has no contact with the workpiece and accordingly, requires very low clamping loads to hold the workpiece in the spindle during the finishing operation. Due to the low clamping loads, the distortion of the workpiece is completely eliminated. Modulating the power supply during the work cycle allows the use of a single tool for both roughing and finishing as a continuous cycle to significantly provide surface finishes previously unobtainable.

In one aspect, a process for roll grinding employs a grinding wheel that is porous and permeable. In another aspect, a process for grinding mill rolls includes dressing the grinding wheel as the wheel traverses the surface of a mill roll. Other aspects relate to a system, e.g., a mill roll grinding machine, or parts thereof, in which a dressing tool contacts the wheel as the wheel grinds the surface of the mill roll. In specific examples, the wheel and a rotary dressing tool are maintained in contact as the wheel traverses the surface of the mill roll.

Preparing tool surfaces for composites
ActiveUS10118315B1Eliminate porositySmooth surface finishAdditive manufacturing apparatusAdditive manufacturing with liquidsSmooth surfaceMicrostructure
Techniques for producing composites outside of an autoclave that have smooth surface finishes are disclosed. The smooth composite surface, free of porosity, can be fabricated by curing the prepreg in a tool that includes a novel microstructure. In conventional composite manufacturing, some degree of porosity appears to originate from trapped gas bubbles that form during curing. The microstructure can provide a mechanism for the gas bubbles to escape from the tooling, thereby eliminating porosity and yielding a smooth surface finish on the out-of-autoclave composite. The microstructure can be applied to the tool surface using an inkjet process applying an acrylic resin curable with ultraviolet light.

Low-thermal-inertia intake ports for port-injected, spark ignition engines and an associated manufacturing method
ActiveUS7360512B1Low thermal inertia characteristicEasy dischargeAir coolingElectric ignition installationHigh surfaceHydroforming
The present invention provides an intake port design that provides a low thermal inertia characteristic, thereby decoupling the surface temperature of the intake port walls from that of the coolant through use of an air gap formed between the intake port and the cylinder head. At idle and part-throttle, the intake port is at a higher surface temperature yielding better cold-start emissions, better mixture preparation, and less dense intake charge (“thermal throttling”) for better fuel economy. At wide-open-throttle, the intake port is at a lower surface temperature yielding better volumetric efficiency for improved torque and reduction in knocking tendency enabling higher compression ratio for improved fuel economy and performance. The intake port design of the present invention can be manufactured with a hydroform manufacturing process resulting in improved dimensional consistency and smooth surface finish. Additionally, the process eliminates some cylinder head machining processes.
