Abstract: TITLE:        NOISE SUPPRESSION DURING               SEISMIC EXPLORATION                        ABSTRACT    The system for suppressing an ambient noise signal which  contaminates  a  desired  signal  includes  a  noise pickup detector for detecting the ambient noise signal.  A noise discriminator processes the detected noise signal into noise data.  A reference noise generator converts the noise  data  into  a  reference  noise  signal.   The noise generator automatically adjusts the reference noise signal to correspond with changes in the noise signal as it is being  detected.   A filter  filters  the  reference noise signal into an error signal which is adapted to remove the noise   signal  from   the   contaminated   signal.    A cross-correlator cross-correlates the contaminated signal with the reference noise signal and adjusts the filter to produce the required error signal.

Title: Catalytic reduction of sulphur dioxide
Inventor: JOHANNES ANTONIUS VAN HELDEN H
IPC: B01J23/22
Filed: 1968-02-29
Abstract: The catalytic reduction of sulphurdioxide by methane to hydrogen sulphide uses a catalyst of manganese sulphide. The reaction proceeds satisfactorily at temperatures above 700 degrees C. cobalt molybdate is another catalyst which can be used, which also requires high temp. between 593 and 705 degrees C. The reaction is carried out at a low space velocity. The present invention provided for the reduction to be carried out at a relatively low temperature and at a high space velocity, at the same time providing elemental sulphur. A combined process is described for the removal of sulphur dioxide from the flue gasses by means of a solid acceptor, regeneration the loaded acceptor with a reducing gas and processing the sulphur dioxide formed in this regeneration to elemental sulphur.

Abstract: The apparatus comprises a sensor element (22) which is fitted into a rod (24) which is movable backwards and forwards and by means of which it can be moved in the interior of a hollow glass container (14) to within the vicinity of the bottom. The sensor element is provided with a movably suspended plate (30) at the bottom. If the plate (30) comes into contact with an obstacle in the form of a glass filament (bird swing or spike) in the interior of the container, it is deflected and actuates a proximity switch which delivers a signal by means of which an ejection device is actuated. The apparatus serves, in particular, for the checking of wide-necked containers in which defects in the form of spikes are considerably more frequent than defects in the form of bird swings.

Abstract: By a first conveying device printing products are fed in an imbricated formation (S), in which each printing product rests on the following one, the fold edge of the folded products forming the trailing edge. The printing products are pushed into an intermediate stack from below. The respectively uppermost product of this intermediate stack is seized in the region of the fold edge by at least one sucker of a sucker arrangement, raised upward and brought into the conveying region (F) of a second conveying device. The latter has individually controllable grippers which are arranged at regular intervals, circulate along a closed path, seize the fold edges delivered by the sucker arrangement and convey away the printing products thus seized. By forming an intermediate stack, from which the printing products are then raised by the sucker arrangement at the desired rate and fed to the grippers, even imbricated formations (S) occurring with irregularities can be processed satisfactorily.

The current supply to the first capacitor (14) is temporarily interrupted by the interrupting means (48) at least during part of the discharge period. The second capacitor (30) operates as an auxiliary capacitor in which the charge is stored which would otherwise have been supplied to the first capacitor (14). After the interrupt period the charge stored in the second capacitor (30) is supplied back to the first capacitor (14) by the supply means (50). In this manner there is achieved that substantially no charge current is lost during a total period of time of a charge and discharge cycle. In the total period of time the whole charge current of the current source ends up in the first capacitor, so that tolerances in the discharge period no longer affect the oscillation frequency of the sawtooth oscillator. <IMAGE>
