Abstract: For producing a drip irrigation conduit (13) having discrete internally located emitter units (6) bonded at axially spaced apart locations of an internal surface thereof, the irrigation conduit (13) is continuously extruded from an extrusion cross-head (2) at a first outer diameter and a first linear velocity and is drawn off through a calibrator unit (8) to a second and lesser outer diameter at a second linear velocity greater than the first linear velocity, the emitter units (6) being continuously supplied on a carrier member (4) which extends from within the extruder cross-head (2) to the region of an inlet of the calibrator unit (8). Whilst so supported the emitter units (6) are accelerated so as to attain an emitter unit linear velocity substantially equal to said second linear velocity and are displaced at this velocity into contact with the extruded conduit (13) where the latter has substantially attained its second linear velocity and therefore continue to be displaced whilst still supported in contact with the extruded conduit (13) until the emitter unit (6) is heat welded.

Abstract: To maintain a constant regulating variable, particularly of the bed temperature of a fluidized-bed combustion plant, a regulating element (24) is used which is arranged in a feed line (20) for feeding fluidization air to a syphon (15), via which solid matter separated from the flue gas of the fluidized-bed combustion plant is fed back into the fluidized bed (5). The actuating drive (23) of the regulating element (24) is coupled to a temperature sensor (27) arranged in the fluidized bed (5), in such a manner that the quantity of fluidizing air is increased when the measured bed temperature exceeds a predetermined value. The quantity of fluidizing air is reduced when the measured bed temperature drops below the predetermined value.

Abstract: In a system for transmitting a binary source signal from a data transmitter to a data receiver through a noisy dispersive channel, the data transmitter comprises a sliding block encoder which converts the binary source signal at a given symbol rate 1/T into an encoded binary data signal at a symbol rate P/TN, where P and N are positive integers such that N/P ≦ ²log(3)/2 + 0.79248. Since the channel introduces intersymbol interference and noise into the encoded data signal, the data receiver comprises the cascade of a equalizer, a sampler and a reconstruction circuit which serves to reconstruct the binary source signal at the symbol rate 1/T. The improved reconstruction circuit consists of a detector in a cascade with a decoder with a decoder with memory, while the equalizer, sampler and detector are arranged for the detection of a ternary data signal at the symbol rate P/(2NT).
