Abstract: A method for the production of cellulose by the batch cooking process, wherein the digester is filled with chips and cooking liquor, and the batch is cooked at elevated temperature and pressure in order to obtain a delignified cellulose pulp in the digester. For the impregnation stage a cooking liquor is used which contains a substantially higher amount of active chemicals than is required for the cooking of the batch, and before the actual delignification stage the active-chemical batch for the cooking is adjusted and the excess amount of active chemicals is removed by replacing it by part of the hot spent cooking liquor recovered from a previous cooking.

Abstract: An internal or external annular surface of a ring which by cold-rolling is to be profiled with accompanying tangential expansion and substantial diametrical enlargement of the ring is preliminarily profiled by a metal-shaping process other than cold-rolling, the preliminary profile having distinctly defined lateral peripheral edges spaced from the lateral walls of the workpiece. The cold-rolling is effected by a cold rolling tool having formed on the working surface thereof facing the preliminarily profiled workpiece surface a profile which is shaped to make local contact with each of the edges of the preliminary profile of the ring and thereby begin compressively stressing the ring by the local contact before the cold rolling conforms the profile of the workpiece to the profile of the tool sufficiently to substantially increase the contact of the tool profile with the workpiece profile. The compressive stressing mitigates tensile stressing accompanying the aforementioned tangential expansion and substantial diametrical enlargement of the ring, thereby preventing the onset of cracking and other defects of the workpiece as the workpiece is cold-rolled.

Abstract: PURPOSE:To obtain an extremely smooth and little wavy interpolation curve by selecting clothoid curves, connecting some of these and making a tangent direction and a curvature on the connecting points continuous. CONSTITUTION:When the coordinates of two points P1 and P2, and a curvature Cv1 and a tangent direction phi1 of the P1 pint are given, one or two clothoid curves to pass these two pints can be drawn. When the position of the P2 point is reasonable, one, and when it is an unreachable position, two clothoid curves are connected as the continuity of a CV and a phi. Even at the time of more than three point, when a point spring itself is smooth, they can be connected by one clothed. Thus, for example, when an illustrated point string 1-12 is given, these points can be connected. On a figure to show the broken-line of the CV to obtain a first approximate value, one straight line is equivalent to one clothoid. The first approximate value of the CV makes the curvature of a circle passing three points including the front and the rear points into the curvature of the point. A circular interpolation is executed to one part between points 5 and 6 and a straight-line interpolation is executed to one part between points 11 and 12.

Abstract: The method involves modifying an encryption key (Kc) in accordance with a given algorithm and in dependence on the ordinal number of a time slot to obtain a modified encryption key. A modified pseudo-random sequence is formed from the resultant modified encryption key. The modification is carried out in accordance with the aid of an encryption algorithm. A logical operation is performed on the modified pseudo-random sequence and for each block of the non-encrypted information. Preferably the operation is performed on the information block that belongs to the time slot whose ordinal number has been used to form the modified encryption key. As an additional option, the frame number can also be modified in accordance with a given algorithm and in dependence on the ordinal number of the relevant time slot. The method provides reliable encryption in TDMA mobile radio systems in which two or more time slots are used for one and the same transmission without requiring any substantial changes to signaling protocol and/or system equipment.

Abstract: The switch device comprises semiconductor switches such as MOSFET-switches (11) connected in parallel between the middle battery cells (7, 9). The switch or switches are generally plate-shaped and comprise each one a main part of body and have one electrical terminal located on a large bottom side and another electrical terminal located on another side of the body. The switches are mounted in a line or a row on a large side of a first electrically and thermally conducting metal plate. A second conducting plate comprises two large sides on an edge connecting the large side. The edge extends in parallel to the switches and at one side of the switches. The second plate is arranged to form a gap between the two plates which are then the electrical terminals of the switch device. Electrical connection wires extend between the terminals located at the other sides of the switches and the second plate. For providing increased heat dissipation the first plate can be prolonged by a bent cooling flange. The switches are controlled by a processor (15) which can receive signals from the exterior, such as rf signals received by a receiver (25) for allowing a high but not too high current for powering a starter motor from the battery. In other cases only small currents can be drawn from the battery for powering the charge state and can block also small currents when there is too little charge left whereby also a sufficient charge can be left for starting the motor. For an interrupt in a lead to a power supply unit the control circuit can be provided with voltage from a reduced number of battery cells. Therefore, suitably placed diodes are provided in the interior supply lines to the power supply unit.
