Patent NL-8200080-A (NL)
Title: Potable water prodn. from well water by membrane filtration - excluding air to prevent pptn. of dissolved e.g. iron cpds.
IPC: C02F1/44
Filed: 1982-01-11
Abstract: The arrangement is intended for producing potable water from water containing dissolved impurities by filtration through a membrane, partic. if the untreated water contains dissolved components, such as iron cpds., which, in contact with air, produce a ppte. e.g. hydroxide, that reduces the effectiveness of the membrane in a short time. Filtration through the membrane is therefore carried out with the exclusion of air. The water may be pumped up from an under -ground water-bearing (e.g. sand) stratum by an immersion pump placed in a well, whilst the upper end of the bore hole is pref. sealed. The filter permeate may be aerated, e.g. in a sand bed filter, and the residual water may be passed back to a (deeper) underground stratum. Used for winning potable water from underground well by membrane filtration. The filter membrane used has a long effective life, thus eliminating regular cleaning and/or replacement. The amt. of water passed per unit filter area remains high over a long period. This filtration combined with subsequent aeration directly produces potable water not requiring the addn. of chlorine etc. as not only soluble impurities such as salts are removed, but also bacteria and viruses.

Patent NL-8900112-A (NL)
Title: Method and device for the transmission of a digital data stream comprising information words and synchronisation words
IPC: H04J3/16
Filed: 1989-01-18
Abstract: The invention relates to a method and device for the transmission of a digital data stream comprising information word groups and synchronisation words. It has hitherto been customary always to precede information words or groups thereof which were to be transmitted with associated synchronisation words. Since variable length coding (VLC) is preferably used to code the information words due to the low required bit rate, the information words or information word groups have different lengths. The synchronisation words therefore have no fixed position and can be detected only by means of an identification code, the length of which must always be greater than that of the longest VLC code word occurring within the data stream. The invention is characterised in that the synchronisation words SW1, ... are positioned at fixed, equidistant intervals in the data stream and furthermore comprise a reference code P which refers to the position of the relevant (for example the next) information word group IWG1, ... . The invention therefore comprises measures for combining information word groups of variable lengths with synchronisation words at fixed positions in the data stream. Very short synchronisation words suffice as a result. Significant data reduction can be achieved in this way.
