Abstract: Disclosed is a lubricant for use in cold forming of a metal. The lubricant comprises a mixture of at least one lubricating compound and at least one starch. The starch adheres the lubricating compound to the metal surface. The present lubricant completely removes the need to pre-coat the metal with a zinc phosphate coating to adhere the lubricating compound to the metal. The present lubricant eliminates several steps required in processes that utilize zinc phosphate pre-coatings. In addition, the lubricant of the present invention is easily removed after the cold forming operations unlike zinc phosphate coatings.

A method of producing a roll of waxed fabric is also provided.

Abstract: Preferably, obtaining internal and external thermal measurement values of a sealed process chamber allows a control system to generate a control signal based on a comparison of the internal and external thermal measurement values to the predetermined value. The control signal is provided to a fluid handling system, wherein the fluid handling system modulates flow of a first fluid around the exterior of the sealed process chamber. The control signal is further provided to a closed loop heat exchange system, wherein the closed loop heat exchange system modulates flow of a second fluid within an interior cavity of the sealed process chamber based on the control signal. The control signal is still further provided to an open loop heat exchange system, wherein the open loop heat exchange system modulates flow of a third fluid within the interior of cavity of the sealed process chamber.

Abstract: Methods for fabricating coatings for implantable medical devices are disclosed. The coatings include hydrophilic and hydrophobic components. The methods provide for treatment of the coatings to cause enrichment a region close to, at or on the outer surface of the coating with the hydrophilic component.

Abstract: A method for recycling an inert gas evacuated from a material deposition process chamber 10 comprises cooling the evacuated inert gas and recirculating a proportion of the cooled gas to the chamber 10 at a first temperature for use as a cooling gas in the material deposition process 12, and recirculating a proportion of the cooled gas to the chamber 10 at a second temperature for use as a shielding gas in the material deposition process 12, the second temperature being higher than the first temperature. Apparatus 22 for recycling an inert gas is also disclosed.

Abstract: Methods for fabricating coatings for implantable medical devices are disclosed. The coatings include blends of hydrophilic and hydrophobic polymers. The methods provide for treatment of the coatings to cause enrichment a region close to the outer surface of the coating with the hydrophilic polymers.

Abstract: A method for manufacturing a coated optical fiber including the step of determining a desired temperature operating range of a coated optical fiber having at least one critical limit. The intercoating delamination stresses at the critical limit of said temperature range are determined. A zero-stress temperature region using the critical limit and the delamination stresses is then selected. An optical fiber is provided and the optical fiber is coated with a first polymer coating. The first polymer coating is exposed to a source of actinic radiation, wherein the source of actinic radiation generates heat. A second polymer coating including a photopolymerizable composition is applied to the optical fiber directly on the first polymer coating. The second polymer coating is cured, where at the time the second polymer coating is cured the first polymer coating is at the zero-stress temperature region.

Abstract: The method for manufacturing coated steel sheet has the steps of: immersing a steel sheet in a hot-dip coating bath to form an Al—Zn base coating layer containing 20 to 95 mass % Al on the steel sheet, forming a passivated layer on the coating layer; and applying thermal history to the coating layer. The thermal history is applied immediately after the steel sheet left the hot-dip coating bath or in a temperature range of from T(° C.) between 130° C. and 300° C. to 100° C.

Abstract: The present invention provides a cooldown chamber allowing more efficient and rapid cooling of a substrate. The substrate is cooled in the cooldown chamber utilizing a pair of cooling members, preferably mating “clam shell” style members, positioned adjacent the top and bottom surfaces of the substrate. While the top surface of the substrate should not be contacted directly, the upper cooling member can approach the substrate surface, preferably to within about 0.01 to about 0.03 inches. The bottom cooling member should also approach the bottom substrate surface, preferably making contact or being within about 0.01 to about 0.03 inches. With the cooling members closed to define an enclosure around a hot substrate, an inert gas is supplied into the enclosure at pressures between about 5 and about 30 torr to allow efficient thermal conduction from the substrate to the cooling members.

Abstract: A high-pressure vessel is allowed to be in an initial state, and a first chamber is disposed downward. Copper or copper alloy is placed in the first chamber, and SiC is set in a second chamber. The high-pressure vessel is tightly sealed, and then the inside of the high-pressure vessel is subjected to vacuum suction through a suction pipe. An electric power is applied to a heater to heat and melt the copper or copper alloy in the first chamber. At a stage at which the molten copper in the first chamber arrives at a predetermined temperature, the high-pressure vessel is inverted by 180 degrees to give a state in which SiC is immersed in the molten copper. An impregnating gas is introduced into the high-pressure vessel through a gas inlet pipe to apply a pressure to the inside of the high-pressure vessel. Thus, SiC is impregnated with the molten copper.

Abstract: A cell adhesion solution of a cross-linked polymer for substrates includes an amino acid polymer, a buffered cross-linking agent, and deionized water (DI H2O). In one example, the amino acid polymer is selected from a neutral or basic amino acid, such as poly 1-lysine or poly 1-arginine. In another example, the amino acid polymer includes poly 1-1sine. In another example, the amino acid polymer includes poly 1-1sine of molecular weight of 100,000 or higher. The cross-linking agent can be selected from an aldehyde functional group, a buffered formaldehyde solution or a 10% neutral buffered formalin solution.
