Title: Process and appliance for treating effluents containing fine mercury-containing particles
Inventor: PANTHENIUS WOLFGANG
IPC: C02F1/52
Filed: 1987-12-02
Abstract: While effluents of dental practices, in particular, have hitherto been freed of mercury-containing drilling residues by commercial filters and grit chambers, fine mercury-containing particles in the form of silt, in concentrations of as much as up to approx. 3% remain in the effluent to pollute the environment. The object of the novel process and the novel appliance is to overcome this problem in an environmentally safe and simple manner. The effluent to be treated is frothed. The fine mercury-containing particles bind to the froth foam. The effluent, freed to 100% of fine mercury-containing particles, is drawn off, with strict separation from the froth. The concentrate of fine mercury-containing particles resulting from the froth is collected and treated with sodium thiosulphate. This converts the mercury into mercury sulphate. Any active constituents of sodium thiosulphate remaining in the residual liquid are treated with calcium chloride, so that, on the one hand, gypsum, and on the other hand, an environmentally safe chloride are formed. The treatment of effluents containing fine mercury-containing particles, especially from places for dental treatment. <IMAGE>

Title: Tunnel shield having a device for comminuting material which can no longer be conveyed
Inventor: GESCHKE GUENTER
IPC: E21D9/06
Filed: 1987-12-18
Abstract: The invention relates to a tunnel shield (1) which preferably functions as an earth pressure shield and has a device for comminuting material which can no longer be conveyed. The tunnel shield (1) bears a winning head (7) and is sealed by a bulkhead wall (4). The bulkhead wall (4) has bores (26) through which crushing or cleaving tools can be introduced into a kneading chamber (17) located behind the winning head (7). Furthermore, bearing devices (27) for abutment elements (28) are provided on the bulkhead wall (4). Obstructions which disrupt the advance of the device, e.g. relatively large lumps of rock, are raised by kneading arms (18), which are arranged at the rear on the winning arms (12) of the winning head (7), and fixed on the abutment elements (28). The comminution of these obstructions takes place by means of crushing or cleaving tools which are introduced, through the bores (26), into the kneading chamber (17) (Figure 2). <IMAGE>

Title: Torsional vibration damper
Inventor: MASBERG ULLRICH DR ING
IPC: F16F15/14
Filed: 1988-03-23
Abstract: Known torsional vibration dampers have the disadvantage that the rubber-elastic interlayer must either be vulcanised on between two rotary bodies or be damaged by impermissibly high local stresses. The torsional vibration damper (1) has an interlayer (4) with an outline (5, 6) which can be described by the superimposition of two circular motions, the centre of the circular motion forming the outline (5, 6) being moved on a circular path that generates the other circular motion, and the ratio of the radii (Rm, e) and the angle of revolution ( sigma , (n + 1) .  sigma ) of the circular motions is chosen so that the outline (5, 6) of the interlayer (4) is curved radially outwards at all points. The torsional vibration damper may be used, inter alia, in motor-vehicle construction. <IMAGE>
Patent DE-3818613-A1 (DE)
Title: Vessel agitator
Inventor: BACHELIER HEINZ-JUERGEN
IPC: B01F15/00
Filed: 1988-06-01
Abstract: In order, on vessel agitators, to be able to exchange the agitator shaft seal at the through flange of the vessel, it has hitherto been conventional to design the so-called lantern ring split and to lift the lantern ring together with the drive via hydraulic lifting cylinders after detaching the shaft. This requires sufficient free space above the agitator. By means of an intermediate shaft (11) mounted on the drive shaft (10) to be able to swing out to the side, it is possible to expose the seal cage and to demount it with simple assembly means. <IMAGE>

Patent DE-3924278-A1 (DE)
Inventor: CONZELMANN GERHARD DIPL PHYS
IPC: H01L27/02
Filed: 1989-07-22
Abstract: Lines are connected into said device from the outside, one of which at least (01, 02) is for supplying the electronical apparatus with operating voltage or operating current and/or at least one is for signal inputs and/or signal outputs. High-frequency alternating voltages can be influenced on said lines through external high-frequency electromagnetic fields, the amplitudes of said alternating voltages being similar to or greater than the momentarily applied line potential, whereby at least one (3) of the PN-junctions directly or indirectly connected to a line (01) and having a blocked operating area is polarized in the conducting direction in the area of the negative half-waves through the influenced high-frequency alternating voltage; rectified currents are thus generated, which inject minority currents into the semiconductor material surrounding the corresponding PN-junction (3), which are at least partially trapped by at least one of the components of the monolithically integrated circuit and whose operating point is shifted, which causes the electronic apparatus to malfunction. The momentary polarization of the closed PN-junction (3) in the conducting direction, occurring in the area of the negative half-waves of the influenced high-frequency alternating voltage, is thereby avoided by means of a diode (5) in the line system.
