Title: Process and sub-soil reactor assembly to clean contaminated flowing or stagnant ground water, exploits natural ground water flow gradient without flow interruption
Inventor: DAFFNER THOMAS
IPC: B09C1/00
Filed: 1999-05-31
Abstract: An in-situ process cleans contaminated ground water (4; 5) within a sub-surface reactor (1, 7) of any chosen design and depth of construction. The reactor takes advantage of the local geophysical situation and hydrographic patterns.  The process exploits the local geo-hydrographic gradient, causing the contaminated water to flow under its own weight through the reactor with adsorbent filter charge (9), which it leaves in a cleaned (10) condition. The reactor may have water-tight walls, reactive walls, and siphon processes. The reactor structure makes use of sub-soil strata (3), or suitable pipes or passages are introduced as required into the ground.

Patent DE-19933814-A1 (DE)
Inventor: APNESETH CHRISTOFFER
IPC: G01S7/285
Filed: 1999-07-20
Abstract: The invention relates to a method and a device for the wireless transmission of information between a base station (2), which emits a broadband high frequency signal that is preferably generated according to the direct sequence spread spectrum (DSSS) method (2); and a plurality of subscribers (1.1 to 1.s). Said subscribers are situated at different distances from the base station. The subscribers encode, modulate and reflect the high frequency signal received back to the base station according to the information to be transmitted and according to the code division multiple access (CDMA) method. The signal is correlated and demodulated in the base station and the base station automatically compensates different propagation dampening between subscribers situated at different distances from the same by combining the correlation function and the propagation damping in an inverse ratio.

Abstract: To prepare a pulp (P) of papermaking fibers with a wood content, from used paper materials (M), a suspension (S) is formed which is cleaned (2) of impurities and is formed into a high consistency (HC) suspension with a solid content of at least 15%. The high consistency (HC) material is ground (4) to reduce the thickness and/or stiffness of the wood fibers while retaining their length. The ground material is diluted and passed through a slit fractionating stage (6), with the overflow (7) returned to the high consistency grinder (4). The fraction passes (8) to a hydrocyclone fractionating station (9), with its overflow also linked to the grinder (4) and its usable material (11) carried off as pulp (P). The high consistency (HC) material is dispersed before dilution. During grinding (4), the high consistency (HC) material is worked with an energy transfer of at least 200 KWh/to and pref. 300-400 KWh/to. The gap between the moving grinding tools is at least 0.5 mm. The grinding is at a temp. of max. 80 degrees C. The specific work of the high consistency grinder (4) is set so that the fiber content of the usable material from the hydrocyclone (9) has a fiber thickness is less than 5% of the paper thickness produced from the pulp (P). The slits in the fractionating stage (6) have a width of max. 0.2 mm, working with a suspension density of 1-4%. Cleaners are used at the hydrocyclone (9) working with force fields of ≥ 800 m/sec<2>, where the suspension has a density of 0.8-1.5%. The material delivered from the grinder (4) is cleaned of the major portion of any hydrophobic matter by flotation (12). The process includes at least one chemical bleaching stage (14'). The process can include a fine grinding action, where the mean fiber length is reduced by ≥ 20%.
