Abstract: In order to break up (break open) crystal lattices of ligand material, tribochemically treated (ground) ligand material is admixed at room temperature, with stirring, with a mixture of an organic and an inorganic acid. The ligand materials take part in a violent reaction with a mixture of organic and inorganic acid, the crystal lattice of the ligand being broken up (broken open) and heavy metals being liberated. The organic acid used may be formic acid and acetic acid, and the inorganic acid may be nitric acid.

Title: Method and apparatus for drying textile articles
Inventor: CHRIST WILHELM
IPC: D06B1/02
Filed: 1987-12-18
Abstract: In a method for drying textile articles, the textile articles are subjected to a forced through-flow by means of a compressor. The gas flowing out of the textile articles is cooled in a cooling device to reduce the water content of the gas by condensation. After the excess water has been separated off, the gas is again supplied to a compressor which forces the gas through the textile articles. In order to be able to control the drying process at a relatively low power level even when, apart from the compressor, the circuit contains no further heat source, a parameter characteristic of the drying process is measured at a point in the gas circuit, preferably downstream of the compressor, in order, depending on this parameter, to readjust the effect of the cooling device after comparison with a command variable.

Patent DE-3806850-A1 (DE)
Title: Twin-hull ship
Inventor: SCHUETT HANS-JUERGEN
IPC: B63B35/32
Filed: 1988-03-03
Abstract: To tackle an oil spill at ships with a cargo of oil or even on drilling rigs, swing-out twin-hull ships are used. These ships have an articulation at the stern, each hull part being provided with a separate expensive rudder propeller. Navigation problems arise in the swung-out state, since the bridge is turned relative to the ahead direction. The swallow-tailed stern shape in the folded state results in poor sea-keeping qualities. Furthermore, separate, expensive units and equipment for tackling an oil spill are installed in each hull part. In order to avoid the abovementioned disadvantages, the articulation of the hull parts 1 and 2 is arranged on a closed stern part 3 containing the propulsion and the control. Likewise, the skimming equipment, the bridge 4 and the lighter equipment are attached to the closed stern part 3. <IMAGE>

Title: Method for the three-dimensional detection and/or determination of a body, in particular a human skull (cranium)
Inventor: NEUMEYER STEFAN DR
IPC: A61B90/00
Filed: 1988-03-08
Abstract: For the purpose of the three-dimensional detection and/or determination of a body, for example a human skull, there is attached on at least one side of the body at least one reference element which has at least three reference points which are mutually offset in space and whose mutual positions in space are known. At least one further reference point is positioned on a measurement point. The position of the reference points on the reference element relative to one another as well as relative to the position of the further reference point is detected optically, and from this the position of the further reference point, and thus the position of the measurement point and/or of a part of the body exhibiting said measurement point is determined, preferably with the aid of a computer.

Patent DE-3812794-A1 (DE)
Title: Rotary pump
Inventor: HAEMMERLE MARTIN
IPC: F04C2/344
Filed: 1988-04-16
Abstract: From the prior art, rotary pumps with eccentrically arranged rotor are known, in which the lamellae or slides arranged displaceably in the rotor are dimensioned in their length to the smallest wall spacing defined by the eccentric position of the rotor. This either leaks or makes the use of sealing elements necessary. A rotary pump with centrally mounted rotor is also already known, but this pump likewise has retractable and extendable sealing elements. In the rotary pump (1) according to the invention, diametrically opposite wall regions (10, 11) with different radii are provided between the pump inlet (5) and the pump outlet (6), the rotor (4) being arranged centrally with respect to these radii. The mutually opposite wall regions (10, 11) with different radii extend over an angular region corresponding to the angle between two adjacent slides (7, 7a). The slides (7, 7a) are made substantially rigid and continuous and are mounted displaceably in the rotor. Located between the wall regions (10, 11) with different radii of curvature are transition wall regions (13, 14), in the course of which the slides (7, 7a) are displaced from their one end position to the other end position. <IMAGE>

Patent DE-3835598-A1 (DE)
Title: Rotary piston compressor with interrupted slip action
Inventor: LEGLEITNER RALF
IPC: F04C18/22
Filed: 1988-10-19
Abstract: In the case of conventional rotary piston compressors, operating on the Wankel principle, three working chambers result. In one of these chambers underpressure arises, thereby producing a negative torque. In addition, in this case only limited inlet and outlet cross-sections are available, so that only low delivery rates can be achieved. By means of the rotary piston compressor according to the invention, the above-mentioned disadvantages are to be eliminated. Since the casing of the compressor, which contains the running path of the piston, is interrupted, only two working chambers result. No negative torque is produced and inlet and outlet openings of almost any size are available. The compressor is to be used as a stationary, but also as a portable compressor, and also as a compressor in car air-conditioning systems.

Title: Process for coating rotationally symmetric, especially cylindrical, substrates with hard material
Inventor: SCHUERER CHRISTIAN DR RER NAT
IPC: C23C16/50

Patent DE-4003116-A1 (DE)
Inventor: BENECKE WOLFGANG DR ING
IPC: H02N1/00
Filed: 1990-02-02
Abstract: A dielectric motor has a rotor which moves with discontinuous angular frequency or stepwise. These operating modes are obtained because the dielectric rotor is electrically asymmetrical or has a non-rotationally symmetrical shape in combination with an external electric alternating field the direction of which can be varied by means of several electrodes. The electronic actuator is shaped so that the operation characteristic of the motor can be varied continuously between that of a continuously operating motor and that of a stepped motor. These motors can be miniaturized to a few micrometres in size and have start-up times in the micro- and millisecond range. These motors can be incorporated as micromechanical components in electronic devices and thus lend themselves to a wide range of application.
