Inventor: OTT KARL-HEINZ
IPC: C02F3/04
Filed: 1979-03-12
Abstract: Process and plant for treating waste water fed via a pump (1) and via a mixing apparatus (2) - admixed with flocculants - into a gravity filter (3), forming a combination filter composed of a support fabric and a primary filter layer. The water passing through this filter becomes enriched with oxygen to close to the saturation point and is then immediately passed over a large-area element (4) which is combined with the gravity filter and in which the filtrate is biologically treated. The biologically treated water is collected in a trough (5) and passed into an outfall either via a settling pool and a further filter part or directly. The constituents separated off in the filter (3) are withdrawn via a valve (6) as still fluent sludge. <IMAGE>

Abstract: A wire stripping tool is described in which the gripping jaw (10) is pivoted mid-way along its length to a frame part and at one extreme end to a lever handle (12). The lever handle is connected to a drawbar (32) by a pair of links (16, 34) so that in closing movement of the lever handle one of the links serves to aid jaw closing, and subsequently the second of the links displaces the drawbar so that a cutting jaw (26) mounted inside the gripping jaw is displaced relative to the gripping jaw.

Abstract: A constructional unit of an apparatus, e.g. the clamping bar of a mechanical printer, is damped in such a way that the noise emanating from the constructional unit (10) is largely eliminated. To reduce the airborne noise emanating from it on the one hand, the constructional unit (10) is provided with damping weights (16) and to reduce the emission of structure-borne noise on the other hand, it is mounted in a damping block (22) which is connected to the apparatus housing (24). A damping film (18) can be arranged between damping weight (16) and constructional unit (10). The damping film (18) and the damping block (22) can consist of rubber. <IMAGE>

Abstract: A PAL coder operates to cause spectrum folding of a luminance input signal Y by multiplying twice the colour subcarrier (44) and adding (42). the resultant being comb filtered (F 12 ) to select frequencies which are multiples of the line frequency. The chrominance signals U, V are combined (48) into U + V and U - V on alternate linesand arethen modulated onto subcarrier. the resultant being filtered in a comb filter (F 12 ) to select frequencies which are odd integral multiples of half the line frequency. The two signals are then added. The comb filters mentioned can in an alternative be based on 313 or 625 line delays. Prefiltering of the Y, U and V signals can be combined with the main comb filtering. The resultant circuitry can be arranged to minimise the use of delays, and uses anaiogue signals throughout. A converse decoder filters then spectrum folds the luminance component, and filters and muitiphes by subcarrier to derive the chrominance. Once a television signal has been encoded by use of the encoder subseguent decoding and recoding produces no theoretical impairment into the signal.
