Abstract: The specification discloses a process for the production of ethyl alcohol (ethanol), the process comprising first and second reaction steps operated in tandem. In the first reaction step, ethyl chloride, hydrogen chloride, perchloroethylene and oxygen are reacted in the presence of a catalyst, using ethane as a diluent, to yield reaction products comprising ethyl alcohol and hexachloroethane. Substantially all of the oxygen and hydrogen chloride reactants of this first reaction step are consumed. The ethyl alcohol is isolated from these reaction products. In the second reaction step, the hexachloroethane from the first reaction step is reacted with ethane to produce the ethyl chloride, hydrogen chloride, and perchloroethylene used as reactants in the first reaction step. These reaction products are supplied to the first reaction step, along with any unreacted ethane.

Abstract: The invention relates to a method for testing the functionality of a spectrometer for faults comprising at least one radiation source, one filter arrangement for separating the radiation into different wavelength ranges, and one receiving arrangement. The invention also relates to a spectrometer comprising a fault recognition device. Reference values are generated at at least two different color temperatures of the radiation source and in the different wavelength ranges. Actual received signals at at least two color temperatures to be set are compared with the reference values in order to test the spectrometer. In the occurrence of variations, the type of variation is determined according to the wavelength ranges and the color temperatures, and definite faults are concluded from the type of variation.

Abstract: A deburring tool for performing non-abrasive deburring of metal and other hard-material parts subject to burring. The deburring tool comprises a portion shaped to engage a specific surface on a workpiece, and surfaced with a deburring material comprising the soft, fuzzy, female loop half of ordinary hook and loop fastener. The female loop half of the hook and loop fastening material is non-abrasive, yet is extremely effective at removing small burrs and shavings from metal parts. In a preferred form, the deburring tool forms a two-sided deburring channel or track through which a part such as a hose connector block having a recessed surface needing deburring can be swiped. Both sides of the channel are surfaced with the female loop half of the hook and loop fastener as the deburring medium.
