Title: Postal sorting and transportation acceleration system method
Inventor: GUENTHER HANS-MICHAEL
IPC: G06Q10/00
Filed: 1997-05-14
Abstract: The method is used to speed up the sorting and transportation of items of postage or freight. The method also simplifies the invoicing process for postage and freight. The transporter provides computer software and/or hardware corresponding to the sender when a service transaction is concluded. The hardware/software must be used to detect the data required for the dispatch of letters or parcels. The hardware/software guarantees that all data required for the logistics and invoicing for the service is detected and printed in the address field of the dispatch forms or paper. The printed information is mechanically read by the transporter and can be processed and used for the logistics and invoicing of the service. An individual machine checkable control code is generated for each letter or item of freight for security purposes. The control code is made up of the address of the recipient, the time of day, the date, the weight and size of the item, the cost of postage, an identification of the sender as well as a continuous numbering or division of these data. The control code is coded or authorised by means of an encoding process which cannot be reversed.

Title: Sub-soil barrier gate for treating ground water
Inventor: RIETZLER JOHANN DR
IPC: B09C1/00
Filed: 1997-07-28
Abstract: In a process and apparatus for purifying ground water bearing a chemical load, the water is collected at a point from which it is released to a reduction filter (F1) and then to an absorption filter (F2) and discharged. The water (GW) migrates towards an impermeable barrier (L) at which it is intercepted and guided towards the filters (F1, F2) which form a two-part gate within perforated walls (S1, S2). Filtered water is released back to the soil on the other side of the membrane (L). The filter material is selected according to the nature of the chemical load and is refreshed as required.  The first filter material incorporates zero valence iron while the second is pyrolusite on a bed of gravel. Preferably at least one filter contains sulphate-reducing bacteria. Preferably the absorption filter contains e.g. manganese oxide or an ion exchanger and removes metal ions.
