Patent DE-2412920-A1 (DE)
Title: Frequency dependent transmission signal control - uses split frequency bands and low pass filter, subtraction, and frequency band delay
Inventor: KERN OTMAR
IPC: H04B1/66
Filed: 1974-03-18
Abstract: One band part is separated by a low pass filter, and the second band part is obtained by subtracting the first part from the total band. Before subtraction the total frequency band is delayed by the propagation time in the low pass filter. After linear or non-linear processing of the band parts, they are recombined and, in order to control the upper band part, a control voltage for the amplifier for this band part is derived from any point of its transmission path after possibly frequency dependent processing. The potential for the control voltage generation is derived from the delay line and is used for forward control. Preferably a low pass filter is inserted into the path of the total frequency band and passes the signal frequencies but cuts off higher frequencies of e.g. 25-30 kHz.

Title: Servo-control unit for road vehicles - has working cylinder with double acting piston and control shaft rotatable in control housing
Inventor: SZUNYOGH LASZLO DIPL ING
IPC: B62D5/24
Filed: 1974-03-26
Abstract: A steering wheel nut is coupled to the working piston by a torsion spring. One end of this spring is fixed to the nut while the other end is attached to the working piston thereby forming a torsion-elastic but axially rigid coupling by means of which axial loading secures the frictionless rotation between the steering wheel nut and the piston. By turning the control column a torque is transmitted to the nut as a consequence of which the torsion spring rotates together with the attached steering wheel nut about the longitudinal axis.

Title: Extensive pressurised sewerage systems - use air compressors for sewage aeration and air scouring of sewers
IPC: C02F3/12
Filed: 1976-06-30
Abstract: A press. sewerage system for collection of domestic sewage over a large region employs continuous aeration of the sewage and air scouring of the sewers by the use of air compressors. Turbo- or piston compressors can be used. The aeration and the scouring compressors are pref. housed in the same building, operating in conjunction with air storage vessels which resuce compressor operation time. Air scour valves are automatically, remotely or hand operated. The amt. of air used is varied with sewage flows. The high press. air is injected through dosing valves. Compared with air-lift pumps (e.g.) installed near houses, health dangers from germ-laden air and formation of noxious odours, are avoided. Disinfection is unnecessary and water is not needed for scouring. Gravity-flow sewers can be used to transport the bulked sewage to the treatment plant. and the overall cost of the system is lower.
