Patent SE-7905005-L (SE)
Inventor: HARNER K I
IPC: F03D7/04
Filed: 1979-06-08
Abstract: The pitch angle of the wind turbine blades (10) is controlled in closed loop manner to maintain either constant electrical generator (26) speed, for isolated power generating stations or when the generator is synchronized to the load, or constant generator (26) output power or shaft torque when the generator is connected to an electrical grid. Open loop acceleration and deceleration schedules are provided to minimize blade stress and shaft torque variations during start up and shutdown transients, limiting blade angle excursions as a function of wind velocity and speed. The gains in the speed (60), torque (64) and power (66) loop controls are scheduled as a function of average wind velocity to optimize stability and response. An anticipatory blade angle schedule responsive to instantaneous wind velocity is added to the desired blade angle reference from the closed loop controls to minimize transient excursions in output power or generator speed resulting from wind gusts. <IMAGE>

Abstract: An epicyclic steering differential for use with a vehicle that is driven by tracks provides steering control and differential action to the vehicle by way of a set of differential cluster gears disposed about the pitch circle of the control gears with which the cluster set mates, engaging concurrently each of two adjacent cluster gears of the set, and driving two oppositely disposed drive gears that ultimately transmit power to the tracks. Each cluster gear has a pitch diameter equal in size to that of the control gears. The clusters are arrayed about the control gears so that the pitch diameter of adjacent clusters are mutually tangent and tangent also with the control gear pitch circle. In this way cluster gear transmits power at two points of meshing contact.

Abstract: When feeding out pumped concrete, in order to eliminate heavy manual work one uses a distributing arrangement which comprises a driven distributing pipe able to rotate in a stand, but one problem has been that the drive system is disturbed by concrete spillage falling down. This is eliminated in that the arrangement comprises a support structure 10 able to swing with the distributing pipe about the pivot of the distributing pipe, carrying the drive elements 16, 17 at a distance from the pivot centre, which act against a ring-shaped vertical trajectory 18, which at the same time ensures that the driving force remains constant. <IMAGE>

Abstract: A telephone instrument circuit including electronic components for functions such as amplifying incoming and outgoing speech signals. When the electronic transducers of each electronic instruments have to operate in parallel with a carbon microphone in another instrument, problems are likely to arise. To deal with the problem, a voltage regulator is used which includes two essentially series coupled comparator-amplifiers, the first of which is driven by the circuit's supply voltage. The second amplifier has its own reference voltage and its output varies the reference voltage VR for the first amplifier, whose output is connected to the line whose voltage is being regulated. Above a preset line current, the I-V characteristic of the circuit is almost flat while below the preset threshold it is fairly steep to enable satisfactory parallel operation.

Abstract: The present invention relates to a method of using and storing energy from the environment using a storage medium, especially silica gel or zeolite, which works by means of chemical reactions or sorptions, in which during charging with energy exergy is accumulated to a high density in this storage medium via an inert gaseous carrier medium for the exergy, and during discharging the stored exergy is extracted from the store, as required, also by means of an inert gaseous carrier medium for conversion into heat or cold of the desired level. The method of the present invention is carried out in such a way that: (a) on charging with energy the exergy of smaller imbalances of the environment is accumulated and/or (b) on discharging energy the residual exergy contained in the emerging gaseous inert carrier medium is used for charging a further storage medium, in which no or only a little exergy is accumulated.
