Title: Centrifugal separator
IPC: H02P29/00
Filed: 1977-08-19
Abstract: A centrifuge for sepg. fluid and solid matter, embraces an outer and an inner drum, the inner drum being laid out as a worm conveyor. The centrifuge is further equipped with a control system for maintaining by means of proportional action, a constant adjusted difference in the speed of revolution between the outer and the inner drum. The control system can also effect by the alteration of the required coupled, a corrective controlling action alongside the proportional controlling action. A pulley coupled to the one drum acts as an electrical generating machine and the speed of revolution of the generator is converted by a tachogenerator into a signal for the proportional regulation of the speed of revolution. After comparison with the adjusted value of the difference in the number of revolutions, the signal provides a target value for the current from the generator and a signal parallel with the generator current is used for the correcting regulating action. The centrifuge is fitted with a cam disc reduction gear between the outer and the inner drum. The generator is coupled to the pulley of the reduction gear driving the inner drum, and means are provided so that when the number of revolutions of the inner drum falls below an adjusted value, a target value of the current from the generator is regulated proportionally or integrally from a signal parallel to the number of revolutions of the generator and a signal parallel to the current from the generator, in such a way that the generator brakes the pulley coupled to the inner drum. Device makes it possible to adjust the speeds of revolution of the inner and outer drum within close limits and maintain these constantly so that the product is as dry as possible. There is no pendulum swinging in the variation of the speeds.

Patent ES-8205088-A1 (ES)
Title: Echo cancellers
IPC: H04B3/20
Filed: 1981-04-08
Abstract: A full-duplex, two-wire Nyquist sampled data communication system includes an adaptive echo canceller (24) at each terminal (e.g., 10'). The echo canceller generates a replica (zm) of the echo component of each sample (rM) of the incoming signal. The replica and the sample are subtractively combined to provide an echo compensated signal (SM). During intervals of simultaneous transmission and reception, i.e., double talk, the echo compensated signal may contain not only an uncancelled echo component but also a far-end data component. An adaptation error signal generator (80), operating in response to a stream of recovered data symbols (e.g., ân), estimates and removes the far-end data component from the echo compensated signal and, in response to the difference, generates an adaptation error signal ( gamma EM-D). This signal is applied as an error signal to the echo canceller. This allows the echo canceller to adapt its set of tap coefficients in response to the uncancelled echo component present in the echo compensated signal. Thus, stable and accurate echo cancellation results even during a double-talk interval.
