Patent DE-2732428-A1 (DE)
Title: Pumping system for natural gas pipeline - uses incoming low pressure gas to cool outgoing warm gas to reduce pressure loss
Inventor: LINDE ROBERT VON DIPL ING
IPC: F17D1/02
Filed: 1977-07-18
Abstract: Natural gas is transported over long distances by pipelines with compressors arranged at intervals in order to restore the pressure drop of the gas after flowing through each stage of the pipeline. The expansion of the gas due to this pressure drop also results in a temp. drop. This temp. drop is utilised to reduce the pressure losses in the system by directing the gas, which has passed through a first pipeline section, into a heat exchanger before it flows to the compressore where the pressure is raised from e.g. 80 bar to 150 bar with a corresponding increase in temp. The warm gas flowing to the next section of the pipeline is then cooled in the heat exchanger by the incoming air from the first section.

Title: Sewage aeration device backflushing - by air flow reversal when fluid pump is shut=off
Inventor: MOLVAR ALLEN EDWARD
IPC: C02F3/12
Filed: 1977-12-20
Abstract: A submerged aeration device with a distributor and radial pipes leading to air/fluid mixing chambers is fitted with pumps for the circulation of the fluid and the supply of air (or oxygen). To remove foreign bodies from the mixing chambers and the fluid pump suction strainer, the fluid pump is stopped and the air supply is maintained. The air flow reversal effects the backflushing. The difference in elevation of the air nozzles and the suction strainer effects a very thorough cleaning which can be intensified by a pulsating operation of the air supply.

Title: Air flow regulation for mine ventilation - utilises digital comparison of required and transducer values to control shutters
Inventor: CZAPLA ANTONI
IPC: E21F1/00
Filed: 1978-01-03
Abstract: Signals from transducers in a mine ventilation system are compared digitally with a demanded value of flow. The difference signal is then used to control servomotors which operate regulator shutters. An electropneumatic transducer (12) is placed in a mine ventilation system to sense speed of air flow. The transducer output is converted (8, 13) to binary code for application to a digital comparator (1) for comparison with a required value (2). An indicator (11) provides indication of the position of flow regulator shutters (5). The comparator output is compensated (6) for disturbance forces and then applied to a power amplifier (7) to drive the motor assembly (4) controlling shutter positions.

Title: Photographic colour processing system for TV transmission - has lenses picking up colours separated in groups for stereo type recording
Inventor: SEEGER ALFRED DIPL PHYS
IPC: H04N13/00
Filed: 1978-02-14
Abstract: A photographic colour image process is adapted for use in TV transmission where three complementary colours are recorded simultaneously. It will separate at least three colours.

It will produce a stereo type recording of the image on the image recorder. The system will incorporate colour filters in the form of spectacles. The filter for the left eye will be tuned differently to that of the right eye. The colour extract groups will be red blue and green. Each extract will produce a black and white extract showing the brightness distribution.

Title: Anti-dip front suspension - has compensating linkage connected to brake mounting provide reaction force
Inventor: BUFLER ERNST DIPL ING
IPC: F16F7/10
Filed: 1978-06-30
Abstract: The brake mounting bracket (6.2) is linked to a compensating lever (6) pivoted about the wheel axle and linked to a second lever (9) by a control rod (8.1). The second lever operates on the suspension to provide an upwards force as the vehicle brakes, derived from the brake reaction force and counteracting the brake dip. The relative link points to the two levers provide an optimum mechanical advantage so that the compensating force balances the brake dip force and ensures a stable ride.
