Abstract: 1,098,956. Signalling size of catch in trawl nets. FUNKWERK KÍPENICK, VEB. Sept. 10, 1965, No. 38714/65. Heading G4H. [Also in Division G1] Apparatus for determining the size of catch in a trawl net comprises a series of catch probes arranged in the cod end one behind another in the direction of towing, each probe including an oscillator (3) of frequency different from the others which is switched on or off when the net is filled up to the position of the probe. In one embodiment, a conductivity bridge is unbalanced when an electrode (6) is covered by fish whereby a transistorized oscillator (3) is switched off.

Abstract: 1351955 Filters C DOUCET 24 Aug 1971 [4 Sept 1970 29 July 1971] 39645/71 Heading B1D A filter apparatus for separating solids from fluids of water, comprises a tubular filter element 5 formed of a plurality of longitudinally extending filaments having a triangular cross-section (see Fig. 2, not shown). Liquid to be filtered is supplied into the tube by inlet 6 and part at least of the liquid is diverted through the filter and removed by outlet 3. The filaments in the filter are arranged so that the filter has a surface filtering action only. Initially, filtration takes place at the upper part of the filter tube surface near the inlet, but as the surface collects filtered solids so the zone of filtration moves down the tube. A further outlet 4' is provided for removal of washing fluid for. cleaning of the filter surface, this outlet being normally closed by a valve 9. If valve 9 is opened, then liquid to be filtered added at inlet 6 will act as washing fluid. The opening of valve 9 may be automatic at set intervals of time or actuated by the pressure drop across the filter surface. To improve cleaning of the fiter surface a gas or liquid, depending on the fluid being filtered, may be added so as to obtain a liquid-gas emulsion to carry out the washing action, e.g. compressed air might be added.
