Title: Telephone call time limitation method - control device connected to extension line, or selected group of lines
Inventor: BOPP FRIEDEL
IPC: H04M3/12
Filed: 1974-07-06
Abstract: The control device sets a time interval derived from the frequency of the charge pulses, and breaks the connection shortly before the end of an adjustable multiple of this interval. This time interval is determined by the number of clock pulses counted between the two control pulses derived from the charge pulses. Before the connection is broken a signal is given a certain time before the permitted time runs out. this signal is acoustically faded-in into the connection. Shortly after the establishment of a telephone connection impulses are accepted by the charge pulse receiver and a flip-flip stage is brought into its working condition.

Title: Homogenising sludges, esp. fibrous sludges and similar slurries - with doubled running speeds and no clogging of the cutting chamber
Inventor: KUEHLEM PETER W ING GRAD
IPC: F04D7/04
Filed: 1974-07-13
Abstract: A device for homogenising sludges, esp. those with a fibrous content, has a cutting chamber enclosed by a cylindrical mantle, into which the sludge is fed from below to escape through openings in the mantle, and a cutting head with tool holders, rotated by a shaft projecting downwards into the cutting chamber. On the leading faces of the tool holders, there are blades, the cutting edges of which run parallel to the vertical axis of the chamber, round the inner face of the mantle, and the blades have at their upper end facing the cutting chamber mantle a stepped back section, and at their lower end a rounding-off which is also set back from the cutting edge. Fibres cannot agglomerate into rings in the cutting chamber, overloading the motor and causing leakages through the packings. Speeds can be raised to 1000 r.p.m. with more efficient homogenising.
