Patent SE-7408158-L (SE)
Inventor: ALLMENNA SVENSKA ELEKTRISKA AB
IPC: H02H1/04
Filed: 1974-06-20
Abstract: For filtering off of low frequency and a periodic transient phenomena in relay protection devices for electric high voltage networks, the signals of which occur in the event of a fault in the network and which are superimposed on the signals supplied to measuring relays arranged in the relay protection device, a normally short-circuited filter is included in a normally open alternative path for the measuring signal which is parallel to a part of the normal signal path. A supervisory circuit includes a time circuit, a fast fault indicator and an undervoltage detector. A signal from the fault indicator breaks the short-circuit of the filter and, upon a signal from the undervoltage detector, connects the filter in the path of the measuring signal. The measuring relay is blocked during a time interval which is equal to the difference between the pulse time of the time circuit and the time of operation of the undervoltage detector. This is accomplished by an AND-gate which has its inputs connected to the fast fault indicator and to the undervoltage detector and its output connected to a make-and-break contact for closing the alternative current path.

Abstract: A method for rapid acquisition and handling of root mean square values of the time dependent current and/or voltage in single or multi-phase a.c. mains wherein each of these values is converted into two intermediate values shifted in phase by 90 DEG  and fed into a computer circuit the output of which provides analog d.c. signals indicating the reactive or actual power, or the r.m.s. values of the voltage and current dependent upon the particular type of computer which is used. The analog d.c. signals are fed into a following regulator unit having an integrating portion to adjust a regulating value to serve as a nominal value which is then compared with an applied actual value and the difference therebetween is then fed into the regulator unit. The control signal at the output of the regulator unit is read periodically and transmitted to a final control element and the regulating value is adjusted during the course of one or a fraction of one cycle of the a.c. mains frequency.

Abstract: The firing target with electronic shot-position determination has at least three acoustic transducers (6) which are arranged at a distance from one another underneath the firing disc (1). The acoustic transducers (6) are used as measurement sensors for the signals which are produced or reflected by a projectile (8). The shot position (S) is determined using two measured propagation-time differences between the propagation times of the signals to the individual measurement sensors (6). The target disc (3) is part of an externally screened sound box (5) in which the transducers (6) are located in direct sound connection with the points at which the shot passes through the front wall of the sound box (5), which is constructed as a target disc (3). The front outer surface, facing the person firing, of the target disc (3) is furthermore constructed to be sound-reflecting with respect to ultrasound, and/or the target disc (3) is constructed to be sound-absorbent. This ensures that any disturbing side effects are precluded, so that the firing target is functionally reliable. Only that sound wave which propagates at the moment directly after the tip of the projectile has penetrated the target disc (3) reaches the measurement transducers (6) and causes the determination of the shot position (S). <IMAGE>

This can consist of one or more layers which connect the building parts on each side of the joint with coating so that variations in the joint's width are transferred to the coating and can be taken up either in that or in secondary joints. Thus one can prevent cracking of the coating. <IMAGE>

Abstract: A method of operating a gas turbine plant which, at the side of the turbine, has a high pressure section and a low pressure section, each of which has connected forwardly thereof a respective combustion chamber and wherein the combustion air is pre-heated. The combustion air, prior to entry into the high pressure-combustion chamber, is initially heated in a pre-heater and thereafter flushes the inner wall of the housing of the high pressure section and thus heats the same. The outlet temperature from the high pressure section is chosen such that it corresponds essentially to the inlet temperature at the housing of the high pressure section. Furthermore, the outlet temperature of the combustion air from the pre-heater is maintained constant, independent of load changes.

Abstract: A tab plater for purposes of stripping tin lead from contact tabs, and replating the same for further preservation and improved electrical contact with metal such as nickel and gold is shown having a plurality of processing stations. The printed circuit boards are passed through various stations where plating or stripping is undertaken and masked by means of the transport system comprising opposed resilient belts and means for sealingly engaging the printed circuit board at a line of demarcation. The printed circuit boards are passed over positioning stations to transfer from one location to another to insure precise positioning of the line of demarcation. The sparger fluid flow at the plating station is controlled by means of a venturi effect created by reversely flowing the fluid over a flow control section immediately adjacent and beneath the line of demarcation whereby selective depth control can be maintained with lower pressures of fluid thereby avoiding excess leakage at the ends of the printed circuit board where a gap exists before the belts form an impervious fluid barrier.

Abstract: A power brake unit for automotive vehicles comprising a brake valve through which pressure-transmitting fluid is metered from a fluid source into a booster chamber to actuate a booster piston. A hydraulic transmission ratio provided by an input piston connected to a brake pedal and an operating piston connected to the brake valve reduces the pedal actuating travel when the fluid source is intact and is ineffective in the event of a failure of the fluid source. Only non-boosted forces are transmitted through the hydraulic transmission ratio. Should the fluid source fail, the hydraulic transmission ratio is rendered inoperative in a simple and safe manner.

Abstract: A quadrature amplitude modulated (QAM) data signal transmitted at T symbols per second is sampled in a data receiver at a rate of 2/T samples per second and applied to a transversal-type equalizer structure (25, 46, 34, 35) having taps spaced at T/2 second intervals. A demodulated equalized signal (aj, bj), generated once every T seconds, is quantized to form a decision (aj*, bj*) as to the value of the original modulating data symbol. An error signal (ej, ej) is formed in response to the pre- and post-quantized values of the demodulated equalized signal. Tap coefficients (ci(j), ci(j)) used in generating the equalized signals are updated in response to (a) a correction term which is a function of the error signal and (b) a predetermined tap leakage term which has a constant magnitude. The introduction of the tap leakage term maintains the coefficient values at minimum levels.

The aim is to achieve a longer life for the electrical power contact nozzle for use in welding heads, especially automatic welding torches and welding guns. An electrical power supply nozzle is to be developed which, as a result of its special design, combines the advantages of a multi-element electrical power contact nozzle (with respect to electrical power transfer and wear) with the requirements for small structural size, simple mechanical construction and high reliability under welding conditions. According to the invention, at least one contact-pressure element is articulated on the wire guidance element with the aid of in each case one thermal bimetallic element, and/or is effectively connected via an expansion element to the wire guidance element, in such a manner that, during a thermal load on the electrical power contact nozzle, the wire guidance element is pressed against the circumference of the filler wire.

Abstract: Damage to plants by browsing animals or insects is reduced by systemically inducing a nonphytotoxic dosage of selenium into the foliage of the plants at a level sufficient to repel animals and insects by means of a selenium compound having a selenium valency not exceeding 4<+>. The method is particularly suited for use in reforestation of pines, firs, and other conifers. The selenium may be systemically absorbed into the plants after application to the surrounding soil in the root zone of seedlings, preferably as a selenium compound, such as sodium or ammonium selenite or dimelamine selenite. Dimelamine selenite is a novel compound.
