20100201589 | DEVICE AND METHOD FOR CONTROLLING A SATELLITE TRACKING ANTENNA - A device for controlling a satellite tracking antenna. An azimuth drive is configured to impart an azimuthal rotational motion to the antenna about an azimuth axis. An elevation axis drive is configured to impart a rotational motion to the antenna about an elevation axis orthogonal to the azimuth axis. A tilt axis drive is configured to impart a rotational motion to the antenna about a tilt axis. The tilt axis is connected to the elevation axis in such a way that the rotational freedom of motion of the antenna about the tilt axis is dependent on the elevation angle such that: at an elevation angle of 0° the rotational freedom of motion of the antenna about the tilt axis corresponds to the azimuthal rotational motion; at an increasing elevation angle the rotational freedom of motion about the antenna successively transcends into a roll rotation; and at an elevation angle of 90° the rotational freedom of motion of the antenna about the tilt axis corresponds to a roll rotation about a roll axis orthogonal to the azimuth axis and to the elevation axis. A control controls the operation of the azimuth axis drive, the elevation axis drive, and the tilt axis drive. The control includes a true north seeking gyro for tracking position, orientation, direction and speed of movement of the device. The control further includes an additional gyro comprising an elevation gyro axis arranged to sense the elevation movement and a tilt gyro axis arranged to sense the tilt movement, so as to minimize the angular velocity of the antenna pointing vector. A method for controlling a satellite tracking antenna, and a vessel including the device. | 08-12-2010 |

20090078103 | DETERMINATION OF BAND SAW FEEDING SPEED - In a method and a system for determining the feeding speed when bandsaw cutting a workpiece, the tooth pitch TP of the bandsaw blade is determined in a first unit depending on the shape and dimensions of the workpiece. In a second unit feeding depth per tooth is determined depending on properties of the workpiece material and the width of the bandsaw blade. The bandsaw blade velocity BS is determined in a third unit from the width W of the workpiece and the hardness of the workpiece material, whereafter the cutting time T is determined in a first calculating unit from the height H of the workpiece, the feeding depth per tooth, the tooth pitch TP and the blade velocity BS. In a second calculating unit the feeding speed MH for the bandsaw blade is then determined by the equation MH=H/T. A computer program, when executed on a computer, performs this determination of the feeding speed when cutting a workpiece with a bandsaw from supplied input data. | 03-26-2009 |

20100217434 | Method and Device for Controlling Motion of an Industrial Robot With a Position Switch - A method for controlling a multi-axis industrial robot or manipulator arranged with a robot control unit. The robot or the control unit includes at least one first computer running a servo controller. A motion limit is configured for at least one axis of the robot arm. A reference signal for a robot position is sent to a robot controller together with a measurement of a position of the robot arm. The reference position is processed and the measured position and the processed reference position are then compared in an evaluator for the purpose of limiting the motion of an arm of the robot. | 08-26-2010 |

20130244049 | ENVIRONMENTALLY FRIENDLY WOOD TREATMENT PROCESS - In order to prolong the usage of wood one needs to prevent the growth of rot and fungi. The most common substances used today are not environmentally friendly and they need to be replaced by more environmentally friendly options. Water glass or sodium silicate has been known for a long time having properties which give the wood resistance to rot and fungi and in addition also fire retardant properties. The present invention discloses a method for treatment of wood to improve the flame retardant properties and also the resistance to rot, fungus, mold and insects of a wooden material. The wood treatment method of the invention comprises the steps of providing a wooden material and providing water based formulation which is stable in room temperature or in temperatures ranging from 15-35° C. The water based formulation of the invention consist essentially of an alkali metal silicate, water and an insolubilization agent which is selected from an organic acid, an inorganic acid or an inorganic polyvalent ion, added in an amount lower than the amount of insolubilization agent needed for the formulation to reach the gelling point. Further the wood treatment method includes the steps of applying the water based formulation on the wooden material and drying the wooden material treated with said water based formulation at any given temperature in order to remove excess of water and also curing the dried wooden material at an elevated temperature in order to insolubilize the alkali metal silicate. | 09-19-2013 |
