5626632 Process for dyeing cationic dyeable polyamide fiber
PatentsALERT A soldering tool that comprises a selected salt, including Group I and II halides such as potassium chloride, for example, that is transparent to infrared energy. A selected salt is formed into a tool having a specific shape for placement during soldering. The tool is used to position and hold component leads during infrared soldering. The tool is formed into a shape that matches the shape of a component and whose leads are to be soldered. The tool is configured so that it may be disposed over the component so that the tool contacts the leads and causes them to contact pads to which the leads. The tool is reusable in that after showing signs of wear, it may be recycled, reformed, and reused. An infrared soldering method for soldering leads to pads comprises the following steps. The tool is fabricated from a material that is transparent to infrared radiation. The tool formed into a shape that matches the shape of the component and contacts the leads to cause them to contact the pads. The tool is placed over the component so that the tool holds the leads in place. Pressure is applied to the tool to provide force to hold the leads in place on the pads. The component and the tool are then disposed in an inert atmosphere in a infrared reflow soldering machine. The leads are infrared soldered to the pads using the infrared reflow soldering machine.
asphalt, from the grinding mechanism and therefore prevents clogging of the asphalt/limestone ore grinding equipment. According to the teachings of the invention, the limestone and asphalt shingle constituents can be ground into fine homogeneous particulate powder that is free of agglomeration. A desired size reduction was achieved. Ninety-eight percent of the homogenous particulate powder passed through a thirty-five mesh screen. Ratios of limestone to waste asphalt shingles ranging from lOO:lO, 100:20, 100:30 and 100:40 were processed through the grinding machinery without any clogging or without causing any build-up of asphalt residue on the grinding mechanism.

STATES
A continuous dyeing, space dyeing or printing process for dyeing cationic dyeable polyamide fibers comprising the steps of applying a premetalized acid or acid dye to the fiber at a pH of 2.5 and below, and the dyed polyamide fiber resulting therefrom. The dyeing process generates cationic dyeable polyamide fiber dyed or printed in light to deep shades without bleeding and without producing badly contaminated dye water effluent.
The invention described in the specification relates to a process and apparatus for the reduction of adsorbable organic halide (AOX), chemical oxygen demand (COD) and color bodies from the filtrates generated in a chlorine compound-containing pulp bleaching sequence. The method involves vigorously and intensely mixing certain pulp bleaching filtrates in order to lower the AOX content of the filtrate and the use of a peroxy compound and a ferrous salt catalyst to treat a combined filtrate streams thereby significantly reducing the level of AOX, COD and color in the effluent leaving the pulp bleaching plant.

Fremont, CA, UNITED STATES
The present invention is directed to means and method for grinding waste asphalt shingles in combination with limestone ore to provide a very fine particulate substance that is suitable as an admix to raw materials used for asphalt shingle production. When grinding the asphalt shingles/limestone ore combination, it was found that the limestone scrubs the asphalt, including temperature softened
