Title: Denitrification of waste water with a nitrate content - by mixing with activated sludge and organic sludge
Inventor: HUBER ANTON
IPC: C02F3/28
Filed: 1992-07-15
Abstract: For the denitrification of waste water with a nitrate content, the sewage is mixed in a container with organic sludge contg a biologically degradable substance and activated sludge to convert the nitrates into molecular nitrogen. The ratio between the biological oxygen requirement of the organic sludge and the total nitrogen content of the water for treatment is more than 3:1 and pref. more than 4:1. The denitrificated water active sludge mixture is separated into activated sludge and denitrificated water, and part of the activated sludge is returned to the container. The denitrificated sewage, or part of it, is passed through a purification assembly to the receiving stream. About 50-80% of the activated sludge is passed back to the compensating container, and the remainder is allowed to rot and form biogas or is used for agricultural use. The denitrificated water, with an ammonium nitrate content, or a part of it is nitrificated in an aerobic reactor and passed back to reduce the biological oxygen requirement in the compensation container. Adsorption and/or flocculating agents are used for the separation of the denitrificated water/activated sludge mixture using aluminium silicates with a high ion exchange performance, a solution of salts with multiple metal values such as Al, Fe(III), Ca and/or Mg salts which can also contain colloid silicic acids, or an organic ion exchange material. USE/ADVANTAGE - The method is for the treatment of wastewater with a nitrate content, such as from metal pickling or dairies, etc. The process is simpler than prior art processes.

Title: Determining characteristic field distribution of interference source - using measurement signal e.g. from multi-channel SQUID gradiometer to form average and correlation values, and normalising
Inventor: ABRAHAM-FUCHS KLAUS DIPL PHYS
IPC: A61B5/04
Filed: 1993-02-15
Abstract: The patient (4) placed within a screened room (2) on a couch (6). Electrical activity (arrow 8) generates electrical and magnetic fields, of which the magnetic field is measured. A multi-channel magnetic measurement system consisting of an array (14) of gradiometers connected to a multichannel SQUID (Super Conducting Quantum Interference Device) (16), both contained within a cryostat container (12). The output signals Mi(t) are processed as follows: a reference signal for each sampling internal in the measurement period t1 to t2 is generated (20), where n is the number of channels and RS(t) is the mean value. A correlation measure Wi for each measurement Mi with RS is calculated over the measurement period (22). The correlation measures Wi are then normalised (24). Noise components are then subtracted from the measurement vectors (M(t) (26) to give a corrected measurement Mi(t). Source signal vectors Qi(t) are then calculated (28) in which signals orthogonal to the interference vector W1 are generated. Finally a corrected source signal vector is calculated for a minimum deviation of the measurement signal (30). USE/ADVANTAGE - Detection of physiological electrical activity in low signal to noise conditions e.g. by measuring bio-magnetic fields. Allows measurement when interfering signal is not spatially constant.

Filed: 1993-05-14
Abstract: In a picking-up device for a walking aid, for example a cane, crutch or the like, with a gripping arm that can be pivoted upward from a starting position into a gripping position, a triggering device which triggers the upwardly pivoting movement of the gripping arm upon contact of the falling cane with the ground, as well as devices for fixing the gripping arm in its starting position and its upwardly pivoting movements, the gripping arm (10) is pivotable in a housing (5) separated from the cane about an axis that is transverse relative to the cane in both directions by about 90 DEG . For transmission of these pivoting movements toothed wheels and a triggering slide (16) with its toothed strip (17) are mounted so as to engage each other tightly in this housing (5). This triggering slide which is displaceably guided in the housing in the plane of the toothed wheels and at right angles to the axles (13, 14) thereof projects by its ends on opposite sides from the housing, so that one of the slide ends touches the floor when the cane is dropped, so that the triggering slide slides back and thus the gripping arm is pivoted upwards. <IMAGE>

Patent DE-4320696-A1 (DE)
Inventor: BONTA JEFFREY D
IPC: H04W36/08
Filed: 1993-06-22
Abstract: A source base-site (109) communicating to a mobile (108) chooses an alternative base-site (110-113) for transmission of a handoff command when required. The source base-site (109) detects when handoff is required, and transmits the handoff command to the mobile (108). If the handoff command does not reach the mobile (108), either after the elapse of a predetermined time period or some other predetermined triggering event, the source base-site (109) will choose an alternative base-site (110-113) 10 transmit the handoff command to the mobile (108) on the same channel. If the mobile (108) receives the handoff command transmitted from the chosen alternative base-site (110-113), the mobile (108) is handed-off.
