Patent SE-0800656-L (SE)
Inventor: ERIKSSON URBAN
Filed: 2008-03-20
Abstract: Method for suppressing side modes during use of a tunable laser of MGY type, having an amplification section, a phase section and a reflector section having a Y-branched waveguide, with a first a second branch, where the laser operation point is defined by feeding a respective current through the phase section, the first and the second branch, where possible combinations of these currents span a three-dimensional space, in which elongated volumes define combinations of currents for which the laser is operated in the same mode and where two-dimensional sections, defined by holding the current through the phase section constant and varying the currents through the branches, through a certain of the volumes constitute modeflats. The two branch currents are controlled within a certain modeflat so that the laser operation point does not coincide with the center of the modeflat, but is sufficiently far from the periphery of the modeflat for mode transitions not to occur, within a predetermined time period, as a consequence of changes related to ageing of the laser, leading to drift of the laser operation point.

Abstract: the invention relates to a mode coupler which, for example is included in an angle tracking system of a satellite to establish a telecommunication between the transmitting and the receiving ground stations. The mode coupler is realized through a circular main wave guide (1) which also can include the feeding horn of the satellite antenna in which a basic mode, for example the TE11-mode of the incoming circular polarized wave guide field appears and which procures two communication channels (f1-f2 and f3-f4 respectively), as well as a beacon frequency (fb). To the main wave guide four rectangular wave guide arms (2a-2d) are connected via the associated apertures (3a-3d). The main wave guide is dimensioned as a mode filter for filtering away the non-desired higher modes TE21 and TM01 and the wave guide arms are dimensioned as a frequency filter for filtering away the frequency bands of the communication channels. From the higher modes TE21 and TM01, the difference- and the sum signals are created in known way to provide a measure of the angle error of the satellite antenna.

Abstract: Method and an apparatus whereby electron beam deep welding can be performed at pressures of more than 10 millibars, especially under atmospheric conditions, without the need for complex apparatus. This is achieved by guide surfaces disposed between a seam and an electron beam source, so as to reflect the diverging electrons and at the same time reduce the free access of the ambient gas atmosphere. The electron reflection and the simultaneous blocking off of gases is achieved by guide surfaces substantially parallel and symmetrical with the beam axis which extend along the beam for at least ten millimeters. The distance between the guide surfaces through the center of the electron beam is greater than the diameter which the beam has upon entering into the higher pressure area.

Abstract: The present invention is directed to a process for preparing cellulose containing water sorptive products from an aqueous suspension or paper furnish in accordance with conventional paper making techniques. The suspension or paper furnish employed in preparing the sorptive products comprises a polymer component and a fibrous component slurried in water. The polymer component is provided from a specifically defined class of crosslinked copolymers which contain carboxyl groups. A representative polymer from this class includes that obtained by reacting methyl acrylate and methacrylate acid in the presence of ethylene glycol dimethacrylate. The polymer component becomes water sorptive when the carboxyl groups present thereon are neutralized with a base. In the practice of the process of the present invention, a composite product is prepared from the above mentioned suspension, partially dried, and then neutralized in a specifically controlled manner. Neutralization is achieved while controlling the amount of base and water which contacts the composite product. The control is exercised in a manner sufficient to achieve a proper degree of salting and to prevent undue sorption of the water during neutralization. Such control results in a substantial improvement in the cost efficiency of the process since the amount of water which must be eventually evaporated from the neutralized product is held to a minimum.
