A process for treating a sour hydrocarbon stream is improved by the use of a dipolar compound which has a positively charged atom and an electronegative group in the same structure. A particularly preferred dipolar compound is ephedrine. The dipolar compounds may be used in conjunction with a metal chelate and a basic solution either in a liquid-liquid process or a fixed bed process with substanti...

An integrated process is disclosed that substantially reduces the cost of producing MTBE and other alkyl tert-alkyl ethers by eliminating a major portion of the equipment and operating costs associated with the downstream processing of the etherification reactor effluent. The integrated process combines the process for the etherification of iso-olefins and methanol, or other alkanols, to produce m...

PURPOSE:To provide smaller hygroscopcity and higher long-term reliability by using a hydrocarbon resin which consists essentially of polyolefins and is added with unsatd. carboxylic acids as a sealing material. CONSTITUTION:The hydrocarbon resin which consists essentially of the polyolefins and is added with the unsatd. carboxylic acids is used as the sealing material to seal the peripheral edge p...

PURPOSE:To make the moisture absorptivity small and to improve the long- period reliability by using fluororesin as a sealing material for sealing the peripheral edge part of a substrate. CONSTITUTION:The liquid crystal display panel which has a medium layer inserted and held between two substrates so that transparent electrode surfaces face each other uses the fluororesin as the sealing material ...

The sludge originating from the treatment of effluents from paint booths with polyurethane powder is filtered and stoved and then mixed with a reactive mixture of polyisocyanates and polyols to obtain a polyurethane foam. Application to the recycling of paint-booth effluents.

The present invention relates to a device for monitoring the operation of a microcontroller or microprocessor, characterised in that it comprises: an oscillator (100) which delivers a timing signal of constant and known frequency, a programmable frequency divider (200) which receives as input the timing signal and delivers at its output a clock signal HC whose period is related to the minimum peri...

A front jaw of a safety ski binding has a sole support (13) which can be pivoted out about two substantially vertical tilting surfaces (15), arranged laterally to the vertical median longitudinal plane (11), of a binding housing (12), this sole support being pre-stressed against the tilting surfaces (15) by means of a release spring (14) with tilting counter-surfaces (16) which acts substantially ...

Tires having white sidewalls are very popular in the United States and Canada. This invention discloses a process for preparing such tires having decorative appliques thereon. By practicing the process of this invention, tires having better uniformity can be built at lower costs than when standard tire building techniques are utilized. This invention specifically relates to a method of preparing a...
