Abstract: ABSTRACT:         This arrangement has for its object to avoid sustained annoying oscillations in a looped system, such as a looped electro-acoustic system or a control system.         It comprises a variable-gain amplifier (11) incorporated in a first path (C1) which forms part of the loop.         Connected between the input terminal (A) and the output terminal (B) of the said first path is a second path (C2) having at least one part which is separated from the first path.  Amplifier (14) is provided to ensure that the gain in the second path remains higher than the gain in the first path in the overall frequency band where the oscillations are liable to be produced.  A signal (W) formed in the said part of the second path which is separate from the first path is applied to the input of a linear regulator 13, which controls the variable-gain amplifier (11) of the first path and variable-gain amplifier (12) of the second path so as to keep the sig-nal at the input of the regulator (13) constant from a certain value of the signal (W) formed in the second path.

Abstract: ABSTRACT OF THE DISCLOSURE              The invention provides an improved assembly tool which is adapted to swedge a ring onto the overlap of a pair of telescoped engaging pipes for securing and sealing them together, and is particularly useful for engaging an exhaust pipe to a muffler outlet. A pair of aligned die blocks, each having opposing semicircular channels of semicircular cross-section, adapted to receive a ring of circular cross-section upon the overlap of a pair of telescoped pipes are provided. A power cylinder has a crosshead which mounts a pair of die supports at their one ends. The die blocks span and are mounted upon the die supports at their other ends. The piston rod engages one of the die blocks for moving it into operative compression with the other die block, the ring forming concentric channels in the pipes, a peripheral seal therebetween, a bead in one pipe nested within the channel of another pipe and with the ring nested and interlocked within one channel.

Abstract: ABSTRACT OF THE DISCLOSURE         A field effect transistor fabricating method comprises forming a surface portion of a semiconductor sub-strate with an impurity region for a channel;  forming a first material layer having a width substantially equal to that of a gate electrode in such a position on the semiconductor sub-strate as is to be formed with the gate electrode, a second material layer having a width larger than that of the first material layer above the first material layer and source and drain regions by ion implantation using the first and second material layers thus formed as a mask.  The source and drain electrodes are formed in contact with the source and drain regions.  A third material layer that has a selectivity with the first material layer in its etching characteristics is formed on the semiconductor body thus far prepared.  An aperture is formed by removing the first material layer using the third material layer as a mask.  The gate electrode is then formed in the aperture.  The resulting transistor has the advantages of being more planar and having a shorter gap between the source and drain regions while keeping the channel length short.  The increased transconductance between source and drain increases the speed of operation.

In the receiver (40), a filter (28) is employed for data recovery.  Data symbols which are received by the receiver (40) are de-coupled by using periodic zeros of an autocorrelation function obtained at the receiver output filter.  The shape factor of filters used in the overall system is selected to be preferably within the approximate range of 1.0 - 3Ø  By selecting suitable slope responses of the aforementioned filters, the duration of the auto-correlation function and the resulting systems may be controlled for optimized results.

Abstract: ABSTRACT   A PROCESS FOR INCREASING THE EFFICIENCY OF OR FOR CLEANING  HEAT EXCHANGERS FOR THE EXHAUST GASES FROM INTERNAL COMBUSTION          ENGINES USED IN STATIONARY INSTALLATIONS            This invention relates to a process for increasing the efficiency of or for cleaning the heat exchangers for the exhaust gases from internal combustion engines used in stationary installations to drive heat pumps or for the coupled generation of electricity and heat, as well as a device for carrying out the process.     Heat exchangers for the exhaust gases from internal combustion engines used in stationary installations, in particular from diesel engines, that are driven with a mixture of heating oil and reclaimed oil cause deposits in the heat exchangers, particularly of soot, so that their efficiency is reduced.  This also means that the overall degree of efficiency of such an installation is reduced or that the mechanical efficiency of the internal combustion engine falls as a result of back pressure.     The process according to the present invention used to increase the degree of effectiveness of or for cleaning heat exchangers is characterized in that the heat exchangers are from time to time heated by the exhaust gases to a temperature that is sufficient for the automatic cleaning of the heat exchanger surfaces, after removal of a liquid secondary thermal transfer medium or when the circulation of a gaseous secondary thermal transfer medium is shut off.
