Title: Supporting wall for industrial building - with framework and wood fibreboard panel impregnated with binder
Inventor: DEMORTIER LOUISE
IPC: E04C2/38
Filed: 1978-05-26
Abstract: A supporting wall for an industrial building is mfd. by temporarily fixing a wood fibreboard panel on a framework, in a horizontal position with the framework facing upwards. Then the whole of the accessible surface of the assembly is coated to saturation point with a liquid binder e.g. polyester capable of hardening on drying and rendering its substrate waterproof.

Title: Piston cylinder unit for punching tool drive - has spring-loaded actuator to couple plunger and working piston
Inventor: GRUELLMEIER ARTUR
IPC: F15B11/032
Filed: 1978-04-26
Abstract: The unit has a rapid stroke and pneumatic/hydraulic pressure transmission. The cylinder housing has a wall, to divide a pressure chamber from the remaining space. The chamber contains a stepped working piston, charged with compressed air for return. There is an oil space on the other side of the dividing wall.

IPC: B01D53/08
Filed: 1978-10-11
Abstract: Various pollutants are removed from exhaust gases by (a) first adsorber with an activated carbon bed to adsorb the SO3, (b) a second activated carbon bed to remove SO2 and nitrogen oxides, (c) a cooling stage between the first and second adsorbers to cool the exhaust gases, (d) lines between the various components to convey the gas. Removal of the SO3 drops the acid dew pt. of the gas to below that at which effective adsorption will take place in the second adsorber. To remove pollutants such as SO3, SO2, Nox etc. from exhaust gases to comply with environmental pollution regulations. The problem with SO3 is that it causes H2SO4 to condense out and cause severe corrosion. By effectively removing this at an elevated temp. the problem is greatly reduced.

Title: Optical superposition reception for Bragg cell spectral analysers - using reference laser beam superimposed on analysed beam
Inventor: SCHALLER WOLFGANG DR ING
IPC: G01R23/00
Filed: 1978-11-25
Abstract: Optical superposition reception system involves sensing light of order (+-) 1 from a Bragg cell with photodetectors at defined angular intervals also receiving a reference beam from the source of the beam being detected. It enables expansion of the dynamic range of spectral analysers. The reference light beam may be deflected in the same Bragg cell as the sensed beam or in a further Bragg cell. The reference light beam frequency lies inside or close to the frequency range of the beam detected by the photodetectors. The split beam from a laser is deflected in two Bragg cells, one controlled by an electrical signal being analysed and the other by a reference signal. Both beams are focussed onto detectors, each of which detects a defined frequency range of the analysed beam. Each detector measures the identical frequency interval, or intervals with a defined shift, from each beam.
