PCT/DK2013/050327H2 LOGIC A/SWISTOFT-IBSEN, Morten
A method for refueling of gas into a pressurized gas tank with repeated adjustment of a target pressure(Ptarget) for the refueling is disclosed, said method comprising the steps of: recording starting conditions for the refueling, establishing a mathematical relation between the recorded starting conditions, the actual refueling time (t_refueling) passed and the target pressure for the refueling, starting the refueling, and repeatedly calculating the target pressure corresponding to the actual refueling time passed and measuring the nozzle pressure of the refueling station, until the calculated target pressure has been reached.

2. WO/2015/055203 CONTROL OF A PUMP TO OPTIMIZE HEAT TRANSFERWO23.04.2015
F24D 19/10
PCT/DK2013/050330GRUNDFOS HOLDING A/SLYHNE, Casper, Hillerup
The present invention relates to a method for controlling a pump for feeding fluid (F) into a heating system (1000). The heating system has a hot fluid tank (HFT) receiving fluid from an associated fluid reservoir line (5) with an incoming fluid mass flow rate (dmcw/dt). A pump (P) receivesfluidfrom the line, and pumps the received fluid with amass flow rate(dmc/dt). A heat exchanging unit (HX) transfers heat (Q) to the fluid (F) from a medium (R).The transferred heat (Q) is maximized by controlling the pump (P1) in response to this information indicative of the transferred heat (Q), the fluid mass flow rate delivered by the pump thereby having a minimum as a function of the incoming fluid mass flow rate (dmcw/dt) when maximizing the transferred heat. The invention provides significantly improved heat transfer to the fluid and power savings for the pump. The invention also relates to a heating system, e.g. a heat pump system.

The invention comprises a machine foot (1), which comprises a top part (3) provided with a lock nut (15), which is mounted in a thread (24) on the spindle (9), where the lock nut (15) has an abutment complementary shaped to the housing (4) of the lower part (2), which abutment forms a section of a sphere, and where there is a first gasket (21) between the spindle (9) and lock nut (15) and where there is a second gasket (22) between housing (4) and lock nut (15). With the invention is achieved that the lower parts (2) and top parts (3) can be produced and stocked as separate and independent units, which for example are not assembled to a finished product until after order, having maintained approved classification of the assembled machine feet (1) after international hygiene standards, at the same time as machine feet (1) produced according to the invention can resist a huge tensions and displacement tensions, which for example can occur in areas having earthquakes, where a machine foot is bolted to the base.

4. WO/2015/055211 CONVERTERS FOR WIND TURBINE GENERATORSWO23.04.2015
H02J 3/28
PCT/DK2014/050331VESTAS WIND SYSTEMS A/SABEYASEKERA, Tusitha
A wind turbine generator 1 supplies three-phase a.c. current of variable voltage and variable frequency to two pairs of rectifiers 4a, 4b and 4c, 4d which generate respective d.c. outputs connected to positive, negative and neutral d.c. conductors 6, 7, 8. The outputs from each pair of rectifiers are connected together, and the outputs from the two pairs are connected in series to create a high-voltage d.c. output. Inverters 10a, 10b, 10c, 10d then convert the d.c. power to a.c. at a fixed frequency and voltage suitable for connection to the mains grid. To reduce the effect of common-mode noise, a capacitor is connected between the 1 neutral conductor7 and earth, and a respective filter circuit 30 is connected between each of the a.c. outputs of the inverters 10a, 10b, 10c, 10d and earth. To reduce the effect of voltage surges during lightning, a surge protection device is also connected between the neutral d.c. conductor 7 and earth. Any imbalance in the current in the positive and negative conductors 6, 8 is compensated by detecting the presence of current flowing in the neutral conductor 7. Power supplied to auxiliary circuits from the output of one of the inverters, e.g. 10a, of the wind turbine is measured, and any resulting imbalance between the current in the positive and negative conductors is compensated. In the event of an earth-leakage fault in the conductors connecting the a.c. outputs of the inverters to the grid, when isolated, isolation detection relays 25 are provided.

The present invention relates to a method for calculating the flow in a gas or a liquid by an ultrasonic flow meter. It is the object of the pending patent application to achieve a very fast calculation of fluid flow, gas or liquid, in a flow channel. A further object is to achieve calculation of flow with extremely low power consumption of the system calculating the fluid flow. This can be achieved by performing condensing and summarizing of the data by use of a mathematic model in order to fit data to the following general model function g(t) = h(t; a4, a5,..., aM). (sin(a1. t + a2) + a3. and by calculating the flow by using either the digital Constant Fraction Discriminator, DCFD, using a part of, or all, of the data frame or by Least Square Fit (LSQF) by fitting measured data to a model function of the type g(t) = h(t; a4, a5,..., aM). sin(a1 . t + a2) + a3, or a combination of DCFD and LSQF for achieving at least Ta, Tb and DT.
