The methods of A.C. generator diagnostics are discussed. The need of developing new methods is justified. A new classification method is presented that is used for diagnostics of A.C. generator damages. Features of the method are specified. Functioning of the method is analyzed based on examination of damages of A.C. generator diodes. The method is compared with other methods of electric machine diagnostics used in practice. Source

The chatter phenomenon can severely limit the power available for milling. The stability lobe diagram (SLD) is a very fast and simple method to predict the chatter free zone, allowing the selection of the most adequate spindle speed and depth of cut for higher productivity. However, the data used to calculate the SLD, coming from frequency response functions (FRFs), must be acquired adequately to improve the predictability. FRFs result differently depending on the activation of the spindle electronic control. The present work uses SLDs to investigate these differences and experimental end milling tests to assess the accuracy of SLDs curves. Results indicate that the inclusion of spindle electronic control provides better accuracy in predicting the chatter in milling. © 2014 by ASME. Source

A large amount of wastewater in the form of oil-in-water is generated in different industries such as olive mills, metal processing and offshore oil and gas. The wastewater treatment equipment market was worth >1 billion in 2010. All the industries face the same problems: to separate emulsified oil from water in a cost-effective way and to handle large volumes of oily waste in an economical way. Among available technologies membrane processes exhibit undisputable advantages over the conventional approaches, especially in treatment of highly emulsified oily wastewater. The O-WaR project aims to develop an integrated process able to efficiently remove emulsified oil from wastewater, to reuse treated water, to recover by-products in wastewater and to reduce volumes of oily waste for disposal. Our solution consists of a SiC membrane coated with an anti-fouling layer, an Induced Gas Flotation (IGF) unit for membrane concentrate treatment and a NF/RO unit for purification of SiC permeate and/or valuable by-products recovery from wastewater. The O-WaR technology will be able to remove >99% of oil, solids and chemical oxygen demand, making treated oily wastewaters to easily meet discharge or reuse requirements, and produce <2% oily waste for off-site disposal, greatly reducing waste disposal cost. In the case of olive mill wastewater (OMW) treatment the O-WaR technology can effectively recover valuable by-products in OMW and create high values (up to 700/kg of recovered small phenolics for functional food, nutraceuticals and cosmeceuticals) for the industry. With the O-WaR technology we expect an annual profit of 1.4 million generated in an OMW treatment plant (20,000 m3/year capacity) and a total annual OPEX savings of 0.17 million for a metal processing factory with 20,000 m3/year wastewater produced compared to using a conventional technology. Also, the SMEs in this project are predicted to have a market opportunity of 11.7 million in first 5 years post project.
