microwave heating: industrial applications (citations from the engineering index data base)

industrialized uses of microwave heating are covered in these citations of worldwide research. the topics include industrial heating and drying for processes such as paper drying, vulcanization, and textile processing. equipment design and safety are also cited (this updated bibliography contains 203 abstracts, 29 of which are new entries..

microbial degradation of dye wastes in aqueous effluents

development of improved wastewater treatment facilities to reduce color and cod in dye-containing effluents is a problem of serious concern for both the textile and carpet industries. existing biological treatment facilities reduce bod to acceptable levels but are generally unsuccessful in reducing cod and color. although previous studies..

cotton effect induced on optically inactive molecules and molecular complexes by optically active environment. iv. circular polarization of fluorescence induced by association of alpha-chymotrypsin and dyes

the induced circular polarized fluorescence (icpf) spectra and the induced anisotropy factors for absorption and fluorescence are measured to find out how the dye binding in an electronically excited state of an alpha-chymotrypsin (alphact)-dye complex differs from that in its ground state. two types of icpf spectra are found: one is a si..

contamination on clothing for staff dealing with the accident at chernobyl

during the first days after the chernobyl accident, there were difficulties in decontaminating staff clothing: the initial suggestion that the dust contamination characteristic of these conditions would be readily removed was not confirmed' results obtained in the laundry in may-july 1986 showed that even severe decontamination, which pro..

energy consumption in a dye works

basic engineering principles were used to estimate the energy consumption in specific areas of a small dye works. processing bulk yarn and fabric with some small quantities of finished products this energy was related to production and space heating requirements and this was found to correspond with historical data. the reduction in fuel ..

nondestructive evaluation instrument surveillance test on 26-inch pipe

a 26-inch-diameter test stand was fabricated to simulate an operating reactor environment. to initiate stress corrosion cracking, an artificial crevice was created by means of water chemistry control and graphite wool techniques. various nondestructive evaluation techniques including acoustic emission and ultrasonic monitoring during oper..

training the dragon to spot the right colours

david evans was established in 1825 and is now the sole remaining london silk printing company. it might come as a surprise to know that it still employs men to walk around the madder tanks with large sticks, stirring the indigo dye (which comes from the madder flower)-although, for the most part, the plant uses modern dying and screening..

theoretical and practical aspects of selected fiber-blend color-formulation functions

color matching blends of precolored fiber using three different methods was studied. best color-matching accuracy was obtained using a two-constant kubelka-munk (km) procedure first-formula color differences averaged 1.6 cielab units and were found to be within the experimental error of 1.6 cielab units useful approximations were obtained..

application of the thyfrec-vt83s to dyeing machines (speed control)

new technology makes it possible to use totally enclosed cage-rotor type induction motors which are of simple and strong construction. thus, machines can be used in adverse circumstances, maintenance labor can be reduced, and control performance can be improved. meidensha recently delivered related equipment to tokai senko, inc. which is ..

laser-induced fluorescence and optical reflection spectra of japanese natural dyes on silk

fluorescence spectra under nitrogen-laser excitation were measured for silk cloth dyed with japanese natural dyes. an identification of the dyes on silk was carried out using a laser-induced fluorescence (lif) technique since dyed cloth has a characteristic fluorescence spectra. moreover, it is possible to identify dyes on faded cloth and..
