Patent SE-0600322-L (SE)
Inventor: SAHA MURARI
Filed: 2006-02-10
Abstract: A method and an adaptive distance protection relay for compensating for a remote line end infeed effect during determination of a distance to a resistive fault on a three-phase power transmission line. It is assumed that a fault current flows through the fault resistance. A fault loop impedance is first calculated by a known algorithm from phase voltages and phase currents. A shift of the fault loop impedance is determined from the fault loop impedance, the impedance of the transmission line for the positive current sequence and the phase angle of a complex fault current distribution factor, where the fault current distribution factor is the ratio of the fault loop current to the fault current. The distance to fault is calculated by subtracting the impedance shift from the fault loop impedance and dividing the result by the impedance of the transmission line for the positive current sequence.

Abstract: In making a lead electrode for a lead-acid accumulator or the like, a supporting body of titanium is pickled in a boiling solution of oxalic acid and then adsorptively coated with a titanium (IV) layer in a treatment bath. This treatment is followed by the anodic coating of the titanium body with PbO2 in an electrolyte containing the ions of lead (II), in the presence of a lead (II) nitrate or a lead (II) salt of an amido, imido, nitrido or fluoro sulfate or phosphate. The treatment bath may be an aqueous solution of an organic titanium salt, the pickling solution, or the electrolyte. If the pickling solution is used for this purpose, the titanium body is anodically connected or the solution is oxygenated. If the electrolyte is utilized, Ti(IV) ions are introduced into that liquid in which the titanium body is immersed for an extended period before closure of the anodizing circuit.

Abstract: A centrifugal compressor assembly for a gas turbine engine includes an inducer section and an impeller section mounted for rotation about an axis. Because leading edges of the impeller blades are cambered, damper pads, extending perpendicular to the low pressure sides thereof also extend axially forward. Blades of the inducer section are indexed rotationally rearward of the impeller blades to improve the distribution of compression gases through the impeller section and high pressure surfaces of the inducer blades mate near their leading edges with outward surfaces of the damper pads. Because the pads and inducer blades vibrate at different frequencies, inducer blade vibrations that might otherwise cause fatigue are attenuated by contact with the damper pads. The damper pad arrangement thus permits the damping of vibrations in the inducer blades notwithstanding the indexed relationship between the inducer section and the impeller section.

Abstract: A training apparatus for aiming and gunnery comprises a target tracer, a central control and monitoring unit and equipment at each of a plurality of anti-aircraft guns or other weapons for combatting moving targets. The target tracer is provided with a range finding radar and a TV camera which, by means of an aiming instrument, are continuously held aimed at a moving target. Furthermore, the target tracer has rotational position indicators for indicating the positions of the radar and the camera with respect to a horizontal and a vertical axis. From information obtained from the radar and the indicators, a data processing unit in the central control unit calculates the correct aiming allowance point for each of the weapons, which points can be shown, on the one hand, one at a time on a common TV monitor, and, on the other hand, on a separate TV monitor for each weapon. In both cases, the field of view observed from each respective weapon by means of TV cameras mounted on the weapons, is overlaid on the TV monitor in question, such that on correct aiming of the weapons, the displayed aiming allowance point coincides with the image of the moving target. For checking that the tracing of the target is effected accurately, use is made of the image, obtained from the TV camera of the target tracer, on the common TV monitor.

Abstract: An integral power steering gear assembly includes a piston and cylinder combination having greater output efficiency through improved fluid balancing and cushioning of the piston at its ends. The improved cushioning utilizes oil capillary slots in lieu of previously proposed epoxy resin strips. The slots may be fed with high pressure fluid filled by feed grooves along the sides of the piston adjacent the output rack. The slots are designed to have a shallow depth, preferably 0.001 inch-0.0025 inch, which is sufficient to provide for high capillary attraction of the oil molecules to the slot. The trapped oil molecules prevent slip stick action, that is molecular interaction between the piston and cylinder wall, but at the same time, the oil molecules remain trapped or isolated within the walls of the slot thereby minimizing leakage from the slot. The operating oil is delivered with higher efficiency in the power steering unit by a bifurcated oil delivery passage communicating with the inlet slot of the piston. This provides fluidized balance and cushioning of the valve within the piston, and also prevents starvation of the high pressure feed grooves and capillary slots for balancing and cushioning the piston within the cylinder. Accordingly, improved reversibility of both the piston and the valve are obtained.

Abstract: The invention relates to method of, and apparatus for, operating an internal combustion engine on low knock-rated fuels as the primary fuel system in which engine knock is anticipated and suppressed by simultaneously detecting actual engine load conditions that may induce such knock and knock condition that actually are occurring in at least one combustion chamber of the engine. In response to such simultaneous conditions, a small but effective amount of anti-knock fluid is supplied to the engine combustion chambers in an amount and for a time sufficient only to suppress knock to a satisfactory level. Such a system permits the use of more economic fuels, such as gasoline, having a substantially lower knock rating than those normally used in automotive equipment and only small but sufficient anti-knock fluid is added solely when the engine is knocking. Such conditions occur over approximately 5-10 percent of road conditions and can readily be supplied by a 1-2 quart container of anti-knock fluid, such as higher knock-rated gasolines, alcohol or the like for each filling of the fuel tank with 10-20 gallons of less expensive low knock-rated gasoline to improve both economic and energy efficiency.

Abstract: The reaction turbine comprises a conducting wheel and a rotating running wheel with rails. Against the direction of the wind are positioned a wind conductor and a central cone. A main wind conductor passes the wind freely at normal speed behind the turbine, where its speed is considerably reduced and braked by the turbine wheel. This means that the wind speed through the cone conductor is free and very immediate, with a vacuum being formed behind the rotating turbine wheel. To ensure that the turbine supplies optimum energy, the wind is conducted in the most appropriate direction using the running wheel rails. To obviate wastage of wind movement energy, the conductive wheel runs in the opposite direction to the running wheel. (Provisional Basic advised week 83/48).
