Title: Chemical sewage treatment - by converting chemicals to gaseous phase and finely distributing as aerosol bubbles
Inventor: MELIN THOMAS DIPL PHYS
IPC: C02F1/76
Filed: 1975-01-21
Abstract: In a chemical treatment of the effluents in municipal sewage plant or neutralization installations, the chemicals are dissolved, if solid, and atomized in a gas or aerosol stream. If gaseous, they are introduced neat or with a carrier gas into a distributor where they are uniformly distributed over the effluents as gas bubbles. The large phase contact area between bubbles and fluid greatly intensifies the mass exchange. The large difference in specific gravity between gas and liquid enables large volumina to be treated by the bubbles in a short time. The feed rate can be easily controlled by monitoring the pH value or the chlorine concentration.

Title: Joint between hollow and solid component - connects firmly inserted component by spherical notches in outer component
Inventor: TSCHERWITSCHKE RICHARD
IPC: B21D39/04
Filed: 1975-07-12
Abstract: A joint is made by inserting a component into the hollow end of another and the two components are subsequently firmly fastened together. The joint is able to carry high loads, and it resists axial pull and twisting. The end of one component pushed into the hollow end of the other component is connected firmly by making notches in the outside component which deform the hollow member walls so that they penetrate into depression formed in thei inner member. These notches are made on both sides of the hollow element. The depression (14, 16) have spherical shape and they penetrate well below the surface of the inner component. This arrangement can be used also for making corner connections without using mitred corners. The notching connection does not cause corrosion as observed on welding of components.

Title: Signalling system between main and PBX exchanges - produces secondary signalling depending on switch condition for simplification
Inventor: JAEGER HORST
IPC: H04M7/14
Filed: 1975-07-23
Abstract: The signalling system with simplified selection devices, passes signals between a main telephone exchange and a PBX. The code digit or code number selected by the calling party is evaluated (depending on the existing switch condition) in order to start a given switching process. Transmission to the called party is controlled by main and/or secondary signalling signals (from the calling party) that differ from the code digits or numbers. This has the advantage that a calling station dialling process leads to different secondary signals depending on the switch condition.
