5626280 Infrared transparent soldering tool and infrared soldering method
PatentsALERT The invention is to apparatus and method for a plasticizing batch process used in manufacturing building materials such as sheet goods, rooting shingles, and various sizes of dimensional lumber products. Recycled waste plastics and other not plastic materials are used in a batch process to plasticize the waste materials into a mixture used in molding various products. A intensive mixture mixes and plasticizes the waste materials of a predetermined weight until the plasticized mixture reaches a predetermine temperature. The material is then expelled to a material mover to dispense the plasticized material by weight to molds in which the plasticized material is pressed to form various products.

CATALYST FOR PRODUCTION OF TERTIARY N-ALKENYL CARBOXYLIC ACID AMIDE, AND PROCESS FOR PRODUCTION OF TERTIARY N-ALKENYL CARBOXYLIC ACID AMIDE USING SAID CATALYST Shimasaki Yuuj; Yano Hitoshi; Ariyoshi Kimio JAPAN assigned to Nippon Shokubai Co Ltd

The present invention provides a catalyst which is an oxide comprising silicon and at least one element selected from the group consisting of alkali metals and alkaline earth metals and which is used for gas-phase intramolecular dehydration of a tertiary N-(Zhydroxyalkyl) carboxylic acid amide to synthesize a tertiary N-alkenyl carboxylic acid amide. This catalyst enables continuous and efficient production of a tertiary N-alkenyl carboxylic acid amide from a tertiary N-(2-hydroxyalkyl) carboxylic acid amide without using any auxiliary raw material, and consequently allows for simple and safe production of a tertiary N-alkenyl carboxylic acid amide without generating any by-product (waste product) derived from the auxiliary raw material.

A process for integration of a steam reforming unit and a cogeneration power plant in which said steam reforming unit comprises two communicating fluid beds; the first fluid bed comprising a reformer containing catalyst and which is used to react steam and light hydrocarbons at conditions sufficient to produce a mixture comprising synthesis gas hydrogen, carbon monoxide, and carbon dioxide, the second fluid bed comprising a combustor-regenerator which receives spent catalyst from the first fluid bed and which provides heat to heat the catalyst and balance the reaction endotherm, by combusting fuel gas in direct contact with the catalyst producing hot flue gas; said cogeneration power plant comprises a gas turbine equipped with an air compressor and a combustor; said integration which comprises drawing off a portion of compressed air from the power plant gas turbine air compressor leaving remainder compressed air; introducing the drawn off compressed air to the combustor-regenerator; mixing the hot flue gas from the combustor-regenerator with the remainder of the compressed air to produce a recombined gas stream and feeding this recombined gas stream to the combustor of the cogeneration gas turbine power plant.

An electronic ignition timing control system including a mechanism for retarding the ignition timing for all or a predetermined subset of the cylinders in a multi-cylinder internal combustion engine during cold starts. Spark timing is reduced for a balanced subset of the cylinders for a short time after the engine is started in order to transfer additional heat to the exhaust system to more quickly raise the temperature of the catalyst and thereby reduce undesired emissions.

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.

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.
