The world-wide energy consumption has almost doubled since 1980 despite efforts towards energy saving and efficiency. This trend is supposed to continue for the decades to come so that major energy crises with electricity cuts and shortage of petrol or gas are anticipated. Furthermore, an ever increasing consumption of fossil fuels significantly contributes to further emissions of greenhouse gases and consequently to global warming in conjunction with catastrophic climate changes. These impacts are reduced to a large extent through utilisation of renewable energy sources for and within decentralised user facilities. The present invention relates to a method of communicating operation modes between a user facility control unit at a user facility and a utility grid control unit of a utility grid. In particular, it relates to a decentralised method of communicating operation modes between a user facility control unit at a user facility with renewable energy supply and a utility grid control unit of a utility grid.

The invention provides method and kit for the separation and purification of cellular components including polar and non-polar metabolites, genomic DNA, RNA and proteins from a single biological sample where two steps of lysis of the cells are performed sequentially, before and after a metabolite isolation step. The first lysis step is mechanical and performed in order to be incomplete, whereas the second is chemical or both mechanical and chemical. A sequential isolation of genomic DNA, RNA and proteins is carried out after the second lysis step. [less ▲]

Feeding more and more multiple non-linear and unsymmetrical power consumers (TV, Computers etc…) cause serious disturbances for the grid quality in terms of voltage harmonics and distortion power in particular in decentralised low power supplies like solar photovoltaic (PV) in households. The use of inverter-fed power devices with modern high speed micro-controllers and an intelligent management of the different powers to be generated can help improving the power quality under any operating conditions. The invention provides a compensation algorithm implemented in a micro-controller combining the use of Finite Impulse Response (FIR) filters to extract the different harmonics from the original voltage signal and applies a Phase Locked Loop (PLL) to every extracted harmonic signal, which is finally compensated via a Proportional-Integral (PI) controller. All the PI controllers outputs are superposed in the final voltage source in such a way that they don’t conflict with each other, leading to a stable voltage source generation with a total harmonic distortion (THD) smaller than the limit of 8% requested by the global European power quality norm EN50160. The active harmonics compensator is able to compensate individually the strongest harmonics due to the feedback effect on the voltage source of any kind of non-linear load at partial-load as well as overload operation. The compensation can be implemented on a self-sufficient single voltage generating power source running in stand-alone or grid-tied. It can also be shared and distributed on multiple voltage source inverters (VSI) of different powers connected on a utility grid. That allows an optimisation of the power production of each device, in particular supplied by variable renewable energy sources (solar PV, wind), taking into consideration its capacity currently available.

The invention relates to a heat exchanger mounting bracket which has a first member with a retaining channel and a second member with a retaining lug. The retaining channel of the first member retains the retaining lug of the second member at an initial mounting position, with a predetermined retaining force, by way of at least a formation on the first member. The retaining channel and lug are releaseable from one another when a force greater than or equal to the predetermined retaining force is applied between the first and second members. A heat exchanger mounting bracket is also provided where a body member is provided with a longitudinal slot toward one end for locating a portion (P) of a heat exchanger, and a pivotal arrangement toward the other end. The pivotal arrangement and longitudinal slot allow displacement of the portion (P) of the heat exchanger from a fore to an aft position upon application of an impact force. [less ▲]

The connecting element comprises a bolt (1) and geometrically defined balls (2) which by a housing (4) and a tube (3) are brought into a defined position and held there. The bolt is introduced into the mechanism consisting of the balls, housing and tube by its contour which conforms to the geometrically defined balls, with a form fit being created between the bolt and the aforesaid mechanism. As the diameter of the mechanism is greater than that of the bore in the connecting halves (6,7) a form fit is created between the connecting element and connecting partners like a screw head.
