Title: Atomiser nozzle for fluid - has nozzle pin projecting into nozzle bore, forming annular gap
Inventor: MEYER FRANZ-JOSEF DIPL ING
IPC: F23D11/38
Filed: 1976-12-02
Abstract: The atomizer nozzle has a deflection chamber, consisting of a cylindrical section with tangentially opening channels and a conical section leading to the nozzle bore. The chamber is limited by a control piston, guided within the cylindrical section, and charged by the fluid against spring pressure. Longitudinal displacement of the piston automatically changes the chamber volume and the channel inlets, dependant upon the fluid pressure. The front end (41) of the control piston (14) carries a nozzle pin (42). The pin projects into the nozzle bore (30), and forms a ring gap (43), which decreases or increases in size with the channel (31) inlets. The rear (33) of the piston has a collar (44) with stops (45), to limit longitudinal piston movements, so that the needle does not touch the nozzle bore.

Title: Annular nozzle - with mushroom shaped centre and gradually decreasing passage area for fluid
Inventor: SEDLACEK FRANZ
IPC: B01J8/44
Filed: 1978-03-18
Abstract: An annular nozzle for the distribution of a medium, e.g. at the bottom of a fluidised bed dryer, has in the centre a mushroom-shaped part which is supported by a U-shaped bracket. This creates a completely free annular passage between the rounded edge of the bore and the inside curves of the mushroom part. The contours of this passage are so designed that the cross-sectional area for the fluid decreases continuously in the direction of flow. This results in a longer service life for the nozzle and an easier replacement, if the mushroom top is joined to the rest by a setscrew.

Title: Biological sewage treatment - in activated sludge basins with suspended bottom aerators for oscillating motion
Inventor: NORDENSKJOELD REINHART VON DIP
IPC: C02F1/00
Filed: 1978-08-09
Abstract: In a biological treatment for sewage, the aerators are placed near the bottom of the activated sludge basins in line, freely suspended from a flexible carrier such as a rope on which the air distribution hose is fixed. The tension of the suspension is low enough to allow a periodical lateral oscillation of the perforated tube aerators. Baffle plates near the outflow create a quiescent zone for the sludge settlement from which a part of the sludge is recycled to the inflow. This system requires much lower capital expenditure for the prepn. and outfitting of the excavated basins. A plant can be enlarged at low cost and its power consumption is very low. Little maintenance is required.
