A method for producing a screening device, the method comprising the steps of providing a screening device that includes a plurality of profiled bars and a plurality of bar holder packages associated with the plurality of profiled bars. The plurality of bar holder packages include a plurality of first bar holders and at least one additional bar holder associated with the plurality of first bar holders. The method including the further steps of inserting the plurality of profiled bars parallel to one another into the plurality of bar holder packages, and bending the plurality of bar holder packages such that the plurality of first bar holders and the at least one additional bar holder are bent at the same time.


A method releases rotor poles of a large electrical machine from the rotor hub, which in the fitted state is located within the stator. In one method step, at least one device is introduced into the air gap between the sector and a rotor pole to be released. The device has a carrier plate and at least one cushion that can be filled with gas and is attached to the carrier plate. In a following method step, the cushions belonging to the device are filled with gas under pressure, the pressure being successively increased until the pole to be released has come away, and in that, in a following method step, the at least one device is removed from the air gap. In a further step, the released pole is pulled out of the rotor hub.

Safety coupling (1) comprising a driving coupling member (3) engaged with a driven coupling member (5) by a frictional connection (6). The frictional connection (6) can be disconnected by activation of a release element (17). The release element (17) can be activated by a centrifugal device (22) wherein a centrifugal unit (24) of the centrifugal device (22) is radial moveable to interact with a shifting gate (50) in dependence of the revolution speed of the centrifugal unit (24) and the slip between the driving coupling member (3) and the driven coupling member (5). The centrifugal device (22) comprises a stop (35, 135) to limit the centrifugal force applied to the centrifugal unit (24).

Method and driveline used for stabilization of an electrical grid. The driveline for electricity generation comprises controllable power unit. Especially a gas motor or a gas turbine can be used as power unit. Further the driveline comprises a generator for electrical power generation. The generator is connectable to an electrical grid for feeding electrical power into the electrical grid. Between the generator and the power unit a torque limiting coupling is arranged in the driveline. To limit the torque the torque limiting coupling is slipping and a limited torque is provided to the generator.

Today, transportation both to/from city-centres and within peri-urban areas, is unsatisfactory in terms of congestion, environmental and societal aspects. To answer identified needs, the Easily diStributed Personal RapId Transit (ESPRIT) project aims to develop a purpose-built, light weight L6 category electric vehicle that can be stacked together to gain space. Thanks to pioneering coupling systems, up to 8 ESPRIT vehicles can be nested together in a road train, 7 being towed for an efficient redistribution of fleets and a smartly-balanced and cost efficient transport system. Within the project, 2 user scenarios are foreseen: a one-way carsharing system within city centres and a last-kilometre personal mobility system to existing public transport infrastructures in peri-urban areas. These will be tested through 3 different geographical use cases (Glasgow, Lyon and LHospitalet de LLobregat near Barcelona). This innovative transport system concept will be demonstrated to TRL5 though state-of-the-art developments of diverse technological bricks (including vehicle and road train architecture, coupling and guiding systems, kinetic and dynamic behaviour management systems, efficient energy supply and rapid charge battery strategies). To prove the ESPRIT concept, the project will also work on modelling and simulation tools to predict, once ESPRIT vehicles are deployed, the economic, social and environmental benefits as well as key operating strategies. This concept will incite citizens to use public transport and carsharing solutions rather than their private vehicles leading to seamless intermodal transport, decongestion, significant reduction of noise and air pollution. To reach all stakeholders, the ESPRIT project will not only rely on its technical expertise but also on the knowledge and network of its end user community represented by several partners as well as the Advisor Board which includes carsharing organisations, public authorities and transport operators.

FIThydro addresses the decision support in commissioning and operating hydropower plants (HPP) by use of existing and innovative technologies. It concentrates on mitigation measures and strategies to develop cost-efficient environmental solutions and on strategies to avoid individual fish damage and enhancing population developments. Therefore HPPS all over Europe are involved as test sites. The facilities for upstream and downstream migration are evaluated, different bypass systems including their use as habitats and the influence of sediment on habitat. In addition existing tools and devices will be enhanced during the project and will be used in the experimental set-ups in the laboratories and at the test sites for e.g. detection of fish or prediction of behavior. This includes sensor fish, different solutions for migration as e.g. trash rack variations, different fish tracking systems, but also numerical models as habitat and population model or virtual fish swimming path model. Therefore a three-level-based workplan was created with preparatory desk work at the beginning to analyze shortcomings and potential in environment-friendly hydropower. Following the experimental tests will be conducted at the different test sites to demonstrate and evaluate the effects of the different options not covered by the desk-work. Thirdly, these results are fed into a risk based Decision Support System (DSS) which is developed for planning, commissioning and operating of HPPs. It is meant to enable operators to fulfill the requirements of cost-effective production and at the same time meet the environmental obligations and targets under European legislation and achieve a self-sustained fish population.

The main objective of the PROVIDES project is to develop a radically new, sustainable and techno-economically feasible pulping technology for wood and agro-based lignocellulose raw materials based on deep eutectic solvents (DES), a new class of natural solvents which have the unique ability to dissolve and thus mildly fractionate lignin, hemicellulose and cellulose at low temperature and atmospheric pressure for further processing into high added value materials and chemicals. The aim is to transfer recent scientific findings in novel lignin dissolving DES to process concept level that can be evaluated against current pulping processes. The technological breakthrough expected through the development of such new DES pulping technology could reduce process energy intensity by at least 40% and investment costs by 50% compared to traditional chemical pulping technology. In parallel, the development of efficient novel cellulose-dissolving DES and other DESs to process lignocellulose materials, starting with paper for recycling, is aimed at with focus on sustainability in selecting DES chemical components and technical and economic applicability of the solvent system. PROVIDES will create both fundamental and industry driven technological knowledge based on lab to bench/pilot scale experimentation, through: mapping and selection of most effective DES families; investigating processes and process technology options, including DES regeneration and recycling, in order to define full industrial processes that would isolate high quality cellulose/fibres, lignin and hemicelluloses; providing products for industrial evaluation; establishing technical data to evaluate industrial feasibility and integration; performing life-cycle oriented assessment of environmental and socio-economic performance; assessing impacts in terms of energy and cost reductions as well as new high added value applications PROVIDES could provide to the pulp and paper industry sector.
