Legislation: Regulation 6/2002 on Community designs art.3(3)(e) Directive 98/71 on the legal protection of designs art.7(1) Cases: Dyson Ltd v Vax Ltd [2010] EWHC 1923 (Pat); [2011] Bus. L.R. 232 (Ch D (Patents Ct)) Lego Juris A/S v Office for Harmonisation in the Internal Market (Trade Marks and Designs) (OHIM) (C-48/09 P) Unreported September 14, 2010 (ECJ) *E.I.P.R. 60 In Lego, the Court of Justice of the European Union denied registration for an exclusively functional shape mark despite the availability of other shapes capable of fulfilling the same function and in Dyson v Vax Mr Justice Arnold established that a design can not be registered for a purely functional shape even though another shape could fulfil the same required function.

Since privatisation, maintenance of DNO LV feeder maximum demand information has gradually demised in some Utility Areas, and it is postulated that lack of knowledge about 11kV and LV electrical networks is resulting in a less economical and energy efficient Network as a whole. In an attempt to quantify the negative impact, this paper examines ten postulated new connection scenarios for a set of real LV load readings, in order to find the difference in design solutions when LV load readings were and were not known. The load profiles of the substations were examined in order to explore the utilisation profile. It was found that in 70% of the scenarios explored, significant cost differences were found. These cost differences varied by an average of 1000%, between schemes designed with and without load readings. Obviously, over designing a system and therefore operating more, underutilised transformers becomes less financially beneficial and less energy efficient. The paper concludes that new connection design is improved in terms of cost when carried out based on known LV load information and enhances the case for regular maximum feeder demand information and/or metering of LV feeders. © 2013 IEEE.

The demand for fresh water production is growing day by day with the increase in world population and with industrial growth. Use of desalination technology is increasing to meet this demand. Among desalination technologies, solar stills require low maintenance and are readily affordable; however their productivity is limited. This paper aims to give a detailed review about the various types of solar stills, covering passive and active designs, single- and multi-effect types, and the various modifications for improved productivity including reflectors, heat storage, fins, collectors, condensers, and mechanisms for enhancing heat and mass transfer. Photovoltaic-thermal and greenhouse type solar stills are also covered. Material advances in the area of phase change materials and nanocomposites are very promising to enhance further performance; future research should be carried out in these and other areas for the greater uptake of solar still technology.
