TheCEDI unit consist of ion exchange membranes, Mixed Bed-12 (MB-12) ion exchange resin and electrodes to remove ion impurities from feed water. The product water from the RO unit is supplied to the CEDI unit. The Quality of the ultra-pure water is determined by the amount of ions present in the water. Higher quality of Ultra-pure water is obtained when the maximum number of ions is transferred through the membranes. The Parameters affecting the performance of the CEDI unit are identified and optimized for maximum ions exchange. Inorder to reduce the number of experimentsTaguchi method was used for optimisation of operating parameters. An orthogonal L array (three factor and three level) was employed to evaluate the effect of feed concentration (35,40and 45 ppm), Flow rate (8, 9 and 10 LPH) and voltage (22, 23, 24 volts). Thus it was observed that increasing the applied voltage anddecreasing the waterflow rateincreases the number of ions transfers through the membrane. However, decreasing water flow rate has certain limits as it decreases the production capacity of the unit. Also it is observed that decreasing the ions in the feed water decreases the overall transfer of ions.</p>10aContinuous Electro-deionization10aIon Exchange membranes10aOptimisation10aTaguchi method10aUltrapure Water1 aThorat, Prathamesh, P.1 aDesale, G., R.1 aGajjal, S., Y.1 aPatil, Sagar, R.  uhttps://library.ncl.res.in/content/optimisation-parameters-affecting-performance-single-compartment-cedi-unit02007nas a2200157   4500008004100000245007600041210006900117260000800186300001200194490000600206520148200212100001701694700001901711700001701730856010201747       2016                        eng d00aRole of helical spring locked washer in bolted join tanalysis: A review0 aRole of helical spring locked washer in bolted join tanalysis A   cJUN  a346-3580 v73 aPurpose-The purpose of this paper is to give a brief introduction of helical spring locked washer along with extensive literatures survey on role of helical spring locked washer in bolted joint analysis. It is very small component of bolted joint assembly, but it play vital role in holding the assembly components together. Helical shape of it produces spring effect in the assembly which is used for keeping the assembly in tension and that is lock the assembly under dynamic loading due to vibrations to avoid the accident. Design/methodology/approach-The critical literatures survey identifies role of helical spring locked washer in different areas such as design optimization, mechanism of loosening-resistant components, bolted joint analysis, finite element-based modeling, analysis and simulation. The related literatures show contribution of helical spring washers in evaluation of anti-loosening performance of assemblies as compare to other types of washers. Findings-It proposed that design optimization of helical spring locked washer is needed as it improves the performance in the form of load-deflection characteristics, load bearing capacity and provides the best locking force for optimize functionality. Originality/value-The originality or value of this paper is to finding research gaps in literatures by dividing literatures into seven different research areas and concentrating the only on role of helical spring locked washer in bolted joint analysis. 1 aWagh, H., K.1 aDesale, G., R.1 aTripathi, K.  uhttps://library.ncl.res.in/content/role-helical-spring-locked-washer-bolted-join-tanalysis-review01673nas a2200157   4500008004100000245010700041210006900148260000800217520107700225100001701302700001801319700001701337700001701354700001901371856012501390       2021                        eng d00aLaser cladding of PAC 718, tribaloy T-700 and METCO 41 C hard facing powders on AISI SS 304L substrate0 aLaser cladding of PAC 718 tribaloy T700 and METCO 41 C hard faci  cFEB3 aThe present investigation aims to deposit the three different hard facing powder (Triboloy T-700 and PAC 718, and TETCO 41 C) on SS 304L using laser cladding technique. The single and overlapped clad track was deposited using 2 kW laser power system. The optimized laser process parameters and 50% overlap clad track was used to deposit a large surface area. The optimum laser process parameters were finalised using single clad structure study.  The cross-sections of the clad layers were used to obtain the microstructure and micro-hardness from different regions namely, clad layer, diffusion layer, and substrate. Throughout the study, the laser power was kept constant i.e. 1.2 kW. For single clad deposition, the scanning speed and powder feed rate varied from 0.3 to 0.5 m/min and 4 to 9 g/min, respectively. T-700 and PAC 718 shows uniform developing micro-structure while METCO 41 C shows the development of mixed dendritic and cellular type microstructure. The Triboloy shows the maximum surface hardness of 534 Hv, 321 Hv for PAC 718, and 294 Hv for METCO 41 C.1 aMore, S., R.1 aBhatt, D., V.1 aMenghani, J.1 aPaul, C., P.1 aDesale, G., R.  uhttps://library.ncl.res.in/content/laser-cladding-pac-718-tribaloy-t-700-and-metco-41-c-hard-facing-powders-aisi-ss-304l
