Abstract: A voice signal compression system (10) includes a variable gain amplifier (14) for amplifying a voice input signal (12) at a gain dependent on a variable control voltage (32). A driver (18) receives the amplified input signal and supplies a power-boosted output signal (20) to an acoustic output transducer, a peak detecting comparator (24), and to a thresold reset timer (26). The comparator (24) produces a digital output that triggers an attack/decay timer (30) which produces the control voltage (32). The comparator (24) initially is set to a high threshold state by the threshold reset timer (26). As the levels and peaks of the input signal (12) increase, the comparator (24) begins to trigger digital pulses to the attack/decay timer (30), and the threshold reset timer (26) begins measuring the duration of the signal which exceeds the threshold of the comparator (24). If the level of the power-boosted output signal (20) exceeds the threshold of the comparator (24) for a preselected time, then the compression threshold of the comparator (24) is switched to a lower level. The threshold remains low until the continuous signal is removed whereupon the comparator (24) is reset to its higher threshold.

Abstract: In a scraper for a conveyor belt (2) with a scraping strip (5) which is pressed against the conveyor belt (2) and can be pivoted out of a normal position into conveyor belt travel direction, the scraping strip (5) is, in addition to the pivotability, sprung radially to the pivot axis (11), as is indicated in the drawing on the right by the double arrow. On pivoting out of its preferably vertical normal position, the scraping strip can thus extend in the radial direction and at the same time the spring force and thus the pressure force decreases. The pressure force in the normal position can, unlike in the known radially sprung non-pivotable strips, be optimised with regard to abrasion without great consideration of the inherent deflection possibility of the sprung scraping strip in the radial direction. The force holding the scraping strip against the pivoting can, unlike in the known pivotable scraping strips, be optimised with regard to deflection without consideration for the pressure force necessary. The pivoting out of the normal position can be set so as to be relatively soft and protective of the belt. <IMAGE>

Abstract: An output level controlling apparatus comprises: a signal attenuating device (1) for attenuating the reproduced output level of a reading/recording signal (PR) read from a record medium; a signal level deciding device (2) for comparing the reproduced output level of the reading/recording signal to a reference signal level previously set; and an output level correcting device (3) for sending a control singal to the signal attenuating device (1) on the basis of the results of the comparison made by the signal level deciding device (2) so as to attenuate the reproduced output level of the reading/recording signal when a reproduced output level is higher than the signal level of the reference signal and so as to decrease an attenuation amount of the reproduced output signal level of the reading/recording signal when the reproduced output signal level is lower than the signal level of the reference signal wherein the output level correcting device (3) sends the control signal so as to rapidly attenuate the reproduced output level of the reading/recording signal and slowly increase the reproduced output level. It is therefore possible to momentarily attenuate a high input level for preventing the output in a high level and prevent the musical environment of BGM from being destroyed and aural sound vibrations from occurring during level adjustment.
