Patent DE-3918452-A1 (DE)
Title: Washing rising gases - by pressurised transverse liq. sprays from annular jets at intervals up column
Inventor: ESCHENBACHER MICHAEL DIPL ING
IPC: B01D47/06
Filed: 1989-06-06
Abstract: Within a vertical column whose open lower end is sealingly immersed in a receiving tank, gas from a tangential lower inlet is freed of its solids and aerosol impurities while rising through one or more transverse screens formed of moving liq. droplets.  The sprayed liq. is emitted at at least 50 m/sec.  by a mixt. forced by pressurised gas from the atomising gaps round superimposed circular nozzles. After impinging on the column wall, the droplets descend to the receiving tank as a continuous film entraining the collected impurities. Cleaned gas impelled by a rotating wheel leaves from a head outlet below the drive motor. An alternative sprayer is of venturi construction. ADVANTAGE - The wet washer effectively removes even fine entrainer particles, while needing little power or maintenance.
Patent DE-3922430-A1 (DE)
Title: Humidity monitor for fibre=optic cable section - uses optical fibre sharply increasing attenuation if dampness enters cable and connected to measurer and evaluator
Inventor: KUNZE DIETER DIPL ING
IPC: H04B10/00
Filed: 1989-07-07
Abstract: Several optical fibres (LW1-LW23) extend along the stretch (OS) of cable. One of the optical fibres (LW23) is so arranged or formed within the conduit or housing (GH) that any dampness (WA) that enters leads to a high increase of attenuation of this fibre. The amt. of attenuation is measured by a meter (DM) connected to this fibre and evaluated to ascertain the ingress of dampness.  Immersion liq. along the fibre (LW23) dissipates or charges the dampness. The latter can mechanically deform the fibre. This effect can be achieved by other material that expands with moisture such that the fibre is either deformed or pushed. USE - Partic. at weak points where the cable is broken, e.g.  splice or junction sleeves, amplifier houses.
Patent DE-3930127-A1 (DE)

Filed: 1989-09-09
Abstract: The rotary tabletting machine has, mounted rotatably in a housing (30), a matrix disc (6), in which the top rams and bottom rams are guided. Of these, the top rams (12) are controlled in a cam ring (14) which is rotationally movably mounted in relation to the housing (30) and the drive shaft (4) and interacts with a measuring device (28, 42), with which its torque is to be measured. As a result, the frictional resistance of the rams during rotation of the matrix disc can be constantly established or monitored and, depending upon this, the supply of lubricants can be controlled.
