Abstract: A target has an acoustic chamber (4) within which microphones (5) are arranged to receive the soundwaves generated by a fired projectile entering said chamber. The microphones (5) are connected to means adapted to establish the hit position of the projectile on the basis of differences in the transit time of the soundwaves to the microphones (5). The acoustic chamber (4) is defined forwardly by a sounddelaying wall (12) having a thickness such that the soundwaves generated by the projectile and passing through the wall will reach each optional point on the inner side of said wall, and thus each microphone (5), later than the soundwaves generated by the projectile as it enters the chamber (4), and this also when the said point is located in a hole previously punched into the wall (12).

Abstract: Longitudinal differential protection system for protection and supervision of power line zones in a distribution system. The protective relays, comprised in the system, are located at each end of the zones that are desired to be monitored. One of the protective relays operates as a master relay for the other slave protective relays. A TRIP function indicating a line fault in any protected zone is performed by transmitting locally processed measured signals to the central protective relay which determines if and when any measure is to be taken. Each local protective relay comprises a measuring device (1), a filter (2) and an A/D converter (3) for phase currents and phase voltages. The digital signals are used to generate a truncated Fourier model of the measured signals in a parameter estimator (4) which cooperates with a frequency estimator (5) and a sampling regulator (6) which, via a synchronization unit (7), ensures that sampling is performed simultaneously in all protective relays included in the protective system. In the parameter estimator the residuals ( epsilon x(t)) of the phase quantities are also generated. Fourier components and residuals are supplied to a logic unit (8) where local loss functions (VLx(t)), based on the residuals, are compared with set threshold values for evaluation of whether an abrupt event in the network has occurred. The current direction and the signs of the residuals at each local protective relay are also determined. By a study of the Fourier components an evaluation can be made as to whether the event is due to a conventional line fault or to a switching in the network. If the event is due to a line fault, information obtained from all local protective relays is transmitted, code-compressed via a signal compression unit (9), to the master protective relay which also comprises a central logic unit (10), wherein a central loss function (VGx(t)), based on the sum of all the current residuals during a certain time from all protective relays, is formed. If this loss function exceeds a threshold value ( eta G), a TRIP function is released.

Abstract: (57) The invention concerns a method for delivering pulp onto the wire of a paper machine into a sheet which in the later stages in converted into finished paper. The thick pulp from the pulping process is suspended with the white water recirculated in the paper machine into a suspension, which is delivered onto the wire into a homogeneous sheet and from which the water drained through the wire is recirculated to the suspension process. The closed circulation allows the enrichment of constituents such as hemicellulose dissolved or dispersed from the stock being prepared that lower water drainage and degrade the retention of fibers. According to the invention, enzymes are added to the lean white water of low consistency that are capable of disintegrating said deleterious constituents. The enzyme can be added to the short circulation of lean white water taking place from the sheet forming on the wire to the suspension process of the pulp, or alternatively, to the long circulation of the white water to other locations of use in the paper machine. The invention is particularly applicable to papermaking based on mechanical pulp such as TMP in which the amount of hemicellulose dissolving in the white water is highest.
