IPC: B01D35/22
Filed: 1983-02-14
Granted: 1986-09-03
Abstract: Industrial water filter comprising a filter housing comprising a sidewall and opposed endwalls, a radial inlet and an axial outlet. A stationary filter is disposed operatively between the inlet and outlet and generally eccentrically relative to the inlet axis so as to produce a sweeping flow pattern along the screen. The interior space between the screen and housing is divided diametrically along an axial plane of the filter housing into two separate channels each of which runs along the screen to a debris recovery zone diametrically opposite the inlet. At the inlet end the interior space is divided by a streamlined flow divider and at the debris recovery end by a separator member which is either a flat plate or a streamlined member. A stiffening web may be joined to the endwalls across an axial plane of the screen. A partition may divide the interior space perpendicularly to the outlet axis into two compartments.

Abstract: A demodulation method is proposed, which demodulates digital signals present in the form of a multilayer analog baseband signal. The baseband signal (UB) is first digitised. A specific number of samples derived from the digitising process are then temporarily stored in succession. These samples are then checked in pairs for correspondence. If the test yields at least two consecutive, approximately corresponding pairs of samples, a mean signal is formed. A mean sample is determined in each case from a specific number of samples. A constant received bit stream is generated using the mean signal, the mean sample and a predetermined bit timing. <IMAGE>
