Title: Plant for cleaning air from spray-booths and metal degreasing appts. - uses mechanical filter, condenser and biological filter
Inventor: SCHIERLOH JENS W
IPC: B05B16/60
Filed: 1990-05-29
Abstract: In plant for cleaning air, in partic. for removing polluting gases, steam and odours, at least two filters are used to remove pollutants.

Title: Biological sewage cleaning - has aeration units in the recirculating basin operated according to ammonia and oxygen@ content
Inventor: MUSKAT JOSEF DR RER NAT
IPC: C02F3/12
Filed: 1991-10-15
Abstract: To control the working of recirculating basin, in the biological sewage cleaning stage, towards the end of the working of the last aeration unit the next but one upstream aeration unit is operated w.r.t. the ammonium nitrogen content. The aeration units which are not operated w.r.t. the ammonium nitrogen content are activated w.r.t. the O2 content in the sewage. The aeration units are downstream of a sewage feed, between the feed and outlet, with the first aeration unit in the chain acting on the ammonium nitrogen content, at a constant level, and the next aeration unit working level is adjusted according to the amount of ammonium nitrogen present. The aeration units working according to the oxygen content, near the end of the next aeration unit, work in sequence against the flow direction of the recirculating sewage. The NH4 content in the sewage is determined upstream of the feed, between the feed and outlet and an initial aeration unit is activated when the NH4 content exceeds a given value. After a given time span, the NH4 content is monitored again and the next but one aeration unit upstream is activated if the NH4 content exceeds the given value. Further upstream units are stopped if the NH4 value is below the limit, and the operation is repeated. ADVANTAGE - The system gives an optimum nitrification of the ammonium nitrogen content.

Title: Borating metal surface, giving wear-resistant feathered lamella coating - by applying paste contg. borating cpd., heating to cause remelting of outer layer, and cooling
IPC: C21D9/30
Filed: 1991-12-04
Abstract: Tough, deformable, wear-resistant borate coatings are applied to metal articles by contacting a powdered formulation contg. B with at least one surface of the metal article and then heating. The novelty is that outer layer remelting of the metal article surface is performed using a high-energy heating source, causing boron or boron carbide components of the borating powder to be incorporated in the remelt layer so that on cooling, a B-contg., feathered lamella structure is formed. ADVANTAGE - Reduced boration times and preselection of coating hardness. Small deformations of the borated layer do not lead to cracking and the process is easily incorporated into a production line

Title: Armrest on door or side wall of motor vehicle - has flexible structure, and moves into fastening surface when under pressure
Inventor: PFADENHAUER DIETER
IPC: B60N2/75
Filed: 1991-12-10
Abstract: The armrest (1) moves at right angles to its fastening surface, when subjected to pressure. It has a full-length structure (6,9), which is elastic at least under pressure. Rigidity is dimensioned, so that under a correspondingly high pressure, a deformation of the armrest takes place, so that a surface is formed, which is approx. flush with the fastening surface (13). The armrest has hinges or full-length rated breaking lines (9) on the inside (7). The lines are stepped relative to a hollow chamber (10), so that the armrest is telescopically moved at right angles to the fastening surface.

Title: Sleeve-valve-controlled pneumatic in-hole impact drill - has sleeve valve tripped by movement of striking piston to allow complete filling of both working chambers with compressed air.
Inventor: HOFERICHTER FRANK
IPC: E21B1/32
Filed: 1992-01-11
Abstract: The stepped striking piston (1) slides backwards and forwards in a corresponding stepped bore of the impact drill body. In the starting position (fig 1) with the drill bit pressed against the work surface, compressed air passes along passages (3,4) and simultaneously fills chambers (6) behind and chambers (5) in front of the piston. The control sleeve (2) is constrained by the friction of self-adjusting ring seal (11) and remains where it is until, just before impact (fig 2), it is carried forward with the piston to close-off the air inlet to the rear chamber (6). With pressure now only in the front chamber (5) the piston returns and moves the control sleeve (2) back to its starting position, thus initiating another impact cycle. USE/ADVANTAGE - Impact drill with better utilisation of compressed air and improved performance within machine dimensional limits.
