Abstract: Analogue and digital signal processors are disclosed utilising interference between wave patterns generated at apertures (e) and at least one detector (f) which can be so located that it lies in a region of destructive interference so that its output is zero if wave patterns are formed at both apertures (e) but finite if a wave pattern is formed at only one of these apertures. Digital input signals are applied to shutters (c) and the output signal from detector (f) is thus a logical function of the two input signals. A similar signal processor is disclosed which utilises acoustic wave patterns and the amplitude on one of or both of the wave patterns may be controlled to enable an output signal to be generated which is an analogue function of input signals.

Abstract: Method for leak detection in a pipeline system, more particularly in a water supply and sewer system. The purpose of the invention is to efficiently and with great accuracy determine the scope and location of damages in the line system. For this purpose leakage indicating means are employed that comprise tracers, which are supplied to the water running through the pipes, each pipe being supplied a special tracer. Samples are taken at certain points downstream in the system. These samples are analysed and the concentration of tracers is determined. Using the concentration figures, the inflow of tracers from adjacent pipes can be established, in respective pipes. Thus, an estimation of the leakage from and to each pipe can be made.

Abstract: A system determines the movement of a track vehicle along the ground, the track vehicle having at least a first rotatable, endless track for supporting the vehicle on the ground, a drive for causing the movement of the vehicle, and a turning system for changing the direction of the movement of the vehicle. The system has a first traction-improvement device for mounting on the track vehicle. It bears on an inner-surface side of the first track with sufficient pressure for a small-surface portion on the opposite side of the first track to engage the ground with a higher pressure than any other portion of the first track, whereby to locate a pivoting axis of the track vehicle in the vicinity thereof. A first speed sensor for mounting on the track vehicle in the vicinity of the small-surface portion on the opposite side of the first track senses the speed of movement of the track vehicle along the ground only in the direction of the rotation of the first track and provides a first information thereof, whereby the movement of the track vehicle may be deduced therefrom. Preferably the vehicle has two tracks, and the system has two such traction-improvement devices and speed sensors respectively for the two tracks.

Abstract: In a pyrolysis plant having a preliminary cooling stage and a final cooling stage, in the event of an operational malfunction of the preliminary cooling stage as indicated by temperature measurement of the pyrolysis gas cooled therein, the pyrolysis gas is withdrawn upstream of the final cooling stage and previously stored, cold pyrolysis gas is drawn from a gas reservoir and fed to the pyrolysis reactor and to the final cooling stage so that these parts of the plant can remain in unaltered operation. As a result of this procedure, a shutdown of the entire plant is avoided in the event of malfunctions of the preliminary cooling stage.

Abstract: Novel polyester molding compositions are disclosed which exhibit unexpected water absorption properties. The compositions of the invention include a polyester base resin (which preferably is a linear poly(alkylene) terephthalate, e.g., poly(butylene) terephthalate, or a copolyester elastomer having long chain ester units derived from corresponding long chain glycols of molecular weight 600-6000 and a carbon to oxygen ratio of greater than 2.5), and a copolyester elastomer having a multiplicity of long and short chain ester units, wherein the long chain ester units are derived from corresponding long chain glycols of molecular height 400-3500 and a carbon to oxygen ratio of between about 2.0 to 2.4. Since the polyester molding compositions of this invention exhibit less water absorption, they may satisfactorily be employed to form parts where low swelling is a desireable physical attribute (e.g. as movable parts of a component having critical spatial tolerances).

Abstract: Signalling of articles at the instant of their submersion into water. A sensor, composed of a diaphragm 2 and a piezoelectric cell connected to a circuit for amplifying and handling the signal, is contained in a box 1. 
<??>Elimination of the effects produced by disturbing frequencies is performed by damping these frequencies when transmitting the vibrations of the diaphragm 2 to the plate 4 of the piezoelectric element by interposing an elastomeric bridge 11, whose characteristics are chosen as a function of the desired passband, between the diaphragm and the plate. With the edges of the plate 4 being inserted rigidly into the body of the box 1 and the diaphragm 2 forming one piece with the box, the latter constitutes an acoustic bridge which transmits to all of the parts of the sensor vibrations received from external sources other than water, so that the diaphragm 2 is in static equilibrium and does not transmit any deformation to the piezoelectric element. 
<??>Attenuation or elimination of frequencies not representative of dropping into water.
