Patent DE-3815187-A1 (DE)
Title: Temperature-controlled installation for thermal waste disposal
Inventor: MAY KARL-WOLFGANG
IPC: F23G5/00
Filed: 1988-05-04
Abstract: The installation contains a pyrolysis reactor (4) which converts the fed-in waste (2) into carbonization gas (g) and pyrolysis residue (r), a combustion chamber (8, 8a), to which the carbonization gas (g) and the pyrolysis residue (r) are supplied after suitable preparation, a heat exchanger (12) which is integrated into the wall of the combustion chamber (8, 8a), and a heating circuit (20-29) for a heating gas (h) for heating the pyrolysis reactor (4), which heating circuit leads from the pyrolysis reactor (4) via the heat exchanger (12) back to the pyrolysis reactor (4). In order that the installation can be readily adapted to different compositions of the supplied waste (2), provision is made according to the invention for there to be included in the heating circuit (20-29) a heat exchanger (22) which removes excess thermal energy from the heating circuit (20-29). In particular, three controllers (34, 40, 46) are provided. The first controller (34) ensures a substantially constant inlet temperature (TE) in the heating-gas inlet housing (4E) of the pyrolysis reactor (4). The second controller (40) ensures a largely constant heating-gas outlet temperature (TA) in the heating-gas outlet housing (4A) of the pyrolysis reactor (4). The third controller (46) maintains the flue-gas temperature (TK) at the end of the heat exchanger (12) in the combustion chamber (8, 8a) within a preset temperature range. All three controllers (34, 40, 46) cooperate to achieve optimal operating conditions despite the fluctuating heat value of the supplied waste (2). <IMAGE>
Patent DE-3823995-A1 (DE)
Title: Foam-gas scrubber
Inventor: GEIER-HENNINGER KURT
IPC: B01D47/04
Filed: 1988-07-15
Abstract: The foam-gas scrubber, as a single-stage or multiple-stage unit, will optimally bind all exhaust gas pollutants, as the values already verify. The NOX group, especially, can not escape from the foam volume, so that at a certain foam height, a 100% separation rate of all pollutants is to be expected. The foam height at the measured values in Mühlhausen-Rixheim was 1200 mm. At a foam height of 2000 mm, the Technical Control Board (TÜV, Germany)/Steam and Electrical Equipment Proprietors' Association (APAVE, France) technicians could not determine any measured values except for zero. The advantages of the foam-gas scrubber are the easy operation and monitoring, and in addition the long service life since everything is fabricated from stainless steel. The conventional catalyst only has a restricted service life; with stationary engine units, 10,000 operating hours are expected, the price per kWh is approximately 300 to 400 DM. The foam-gas scrubber can be constructed below this kWh price, but it has a service life of over 25 years and the neutralising agent to be used, seen in relation to the efficiency, is low and cheap. In addition, the foam-gas scrubber is highly economical, since three functions are performed in one apparatus:     1. exhaust gas scrubbing   2. heat recovery 3. noise reduction when the engine is operating.

Title: Contactless, digital linear transmitter
Inventor: SCHULZ KLAUS-DIETER
IPC: G01D5/36
Filed: 1988-11-02
Abstract: In a contactless, digital linear transmitter for generating a digital signal in accordance with the travel of a linearly movable slide (80), the light-emitting means (42) and the light-receiving means (54) are arranged in a stationary fashion. The light-emitting means (42) transmit light bundles (88) parallel to the travel of the slide (80) and to the pattern. For each light bundle (88), the slide (80) has a first reflecting surface (86) on a first side of the pattern (60, 62, 64, 66), whose surface normal forms with the light bundle (88) an angle of 45@ such that the light bundle (88) is deflected by 90@ and impinges at right angles on the pattern (60, 62, 64, 66). Furthermore, for each light bundle (88), the slide (80) has a second reflecting surface (98) on the second side of the pattern (60, 62, 64, 66), whose surface normal forms with the deflected light bundle (96) an angle of 45@ such that the light bundle (96) is deflected by 90@ and is incident on the stationary light-receiving means (54) along the travel of the slide (80) in an antiparallel fashion relative to the light bundle (80) emitted by the light-emitting means (10; 42). <IMAGE>

Patent DE-3838541-A1 (DE)
Title: Method for charging a supply container with a dry mixture and apparatus for carrying out the method
Inventor: LADWEIN BERNHARD
IPC: B65G69/18
Filed: 1988-11-14
Abstract: The patent application relates to a method and an apparatus for carrying out the method for charging a supply container with a dry mixture comprising a plurality of fine- and coarse-grained materials, the mixture being fed at the upper side of the supply container and passes, via an inlet, into the supply container. In the charging of supply containers for dry mixtures, in known installations, the mixture falls through the container in free fall and, as a result, is partially separated again. The method according to the invention and the novel apparatus are distinguished in that the dry mixture is filled into a concertina-like hose which is attached to the inlet of the supply container and which, under the weight of the mixture, stretches as far as the bottom of the container and is raised again by means of a controlled drive, the mixture emerging into the supply container in relatively small quantities without separation of the individual materials resulting.

Title: Sound-insulating screen
Inventor: BOETTICHER INGO VON DIPL ING
IPC: G10K11/172
Filed: 1989-01-25
Abstract: The invention relates to a sound-insulating screen having a rectangular box frame in which a filling made of an absorber material is arranged, as well as having planiform resonance absorbers partly covering the free ends of the box frame. It is the object of the invention to propose resonance absorbers of this type which are more versatile in application as compared to the known resonance absorbers. According to the invention, this object is achieved in that the resonance absorbers in each case cover one half of an end approximately bounded by a diagonal. By means of this solution according to the invention it is guaranteed that the sound-insulating screens can be used arranged both standing and lying down.

Title: Tread for tyre to resist aquaplaning - is thicker in centre of tread
Inventor: KRAEMER HORST
IPC: B60C9/18
Filed: 1989-07-25
Abstract: A pneumatic tyre for motor vehicles has an  enhanced protection against aquaplaning because the height of the blocks in the centre of the tread is made greater, i.e. the tyre has an inward bulge so that the slits between them can absorb and deduct more water. The prefd. profile depth in the centre is 12 mm as against 8 mm along the tread ends. ADVANTAGE - This deals with the risk of aquaplaning even in case of cloudbursts or deeply flooded traffic lanes.
