Title: Water intake screen installation and method of straining water
IPC: B01D33/00
Filed: 1979-07-05
Abstract: A water intake screen installation has a traveling water screen unit, that is positioned between a water intake and a stream of water flowing in a channel, to strain a quantity of water diverging from the channel stream towards the water intake. The screen unit includes an endless belt strainer in the form of a loop and a drive for revolving the strainer. The strainer has a screening surface, that extends in a predetermined direction of stream flow in the channel and in an upwardly direction. Means are provided for directing a backwash current, through the screening surface, towards the stream of water flowing in the channel, at an elevation below the stream surface. Material, such as refuse and aquatic life, retained on the screening surface can be dislodged by the backwash current. This current forces such material backwardly from the screening surface, into the stream of water flowing in the channel, to be carried away therewith. Also disclosed is a method of straining water from a stream with the above described screening installation that enables water to be drawn from the stream without the removal of aquatic life and refuse.

Patent ES-8400641-A1 (ES)
Title: Apparatus for optically scanning a disc-shaped record carrier
IPC: G11B7/09
Filed: 1982-11-24
Abstract: An apparatus for optically reading a disc-shaped record carrier, which apparatus comprises a radial tracking control system which employs a radial error signal obtained by comparing two signals supplied by two radially adjacent detectors. In order to stabilize the loop gain of the control loop at a constant value, a measuring signal of predetermined frequency is injected into the control loop. The response of the control loop to said injected signal is compared with the injected signal, which comparison results in a control signal for a controllable amplifier circuit. Suitably, said comparison is a phase comparison. The injected measuring signal causes the scanning beam to oscillate relative to the track to be followed. By measuring the correlation between said oscillation signal and the amplitude of the information signal being read, a signal can be obtained which is a measure of deviations, not caused by tracking errors, between the signals supplied by the two detectors and which may be used for correction purposes.

Title: Power supply circuit for an electrostatic dust separator.
IPC: B03C3/68
Filed: 1983-11-02
Abstract: The pulse voltage for the electrode (12) of a dust separator (10) is generated by a thyristor circuit (19) to be transferred to a dust separator through a transformer (16).
