Title: Process for the generation of low absolute pressures for the processing of oils and fats
Inventor: HUPE ADOLF DR ING
IPC: B01D1/28
Filed: 1987-08-14
Abstract: Process for the generation of low absolute pressures for the treatment of oils and fats, in which exhaust steam from the process, which contains oil and fat components, fatty acids and/or tallow as well as steam, is deposited by co-condensation using essentially circulated cooling fluid and cooled down before reuse in the co-condensation. The cooling fluid is cooled down by partial evaporation (flash evaporation). The cooling fluid itself is eventually generated by condensation of the exhaust steam from the process and essentially consists of water and of oils, fats, fatty acids and/or tallows which are emulsified and/or suspended in the water. The partial evaporation of the cooling fluid prevents the removal of heat being impeded by crystallised fat layers on the surfaces of the heat-transfer devices normally used. At the same time, the partial evaporation results in a condensate which is virtually completely free of oils and fats as waste water which does not pollute the environment. It is additionally possible to carry out the deposition of the oils, fats, fatty acids and/or tallows only after the cooling down. The condensation of the steam from the partial evaporation is carried out at temperatures above 0@C in continuous operation. If the process is applied at temperatures just above 0@C, there are advantages in the good effect of the deposition of the oils and fats and ... Original abstract incomplete. <IMAGE>

Patent DE-3739180-A1 (DE)
Inventor: MEDERER WERNER
IPC: H04N17/06
Filed: 1987-11-19
Abstract: The recording current necessary for recording a video signal is always to be optimally selected and adjusted with respect to the replay sensitivity, having regard to an audio signal already recorded on the same tracks and having regard to tolerances of the recording medium, of the heads and of the head amplifiers, by means of the novel method. For this purpose, the recording current is changed in steps during the recording of the video signal. After each change in the recording current for the video signal, a direct-voltage value is determined from the replay envelope curve of the audio signal as a measure of the replay amplitude of the audio signal. As soon as the direct-voltage value obtained from the replay envelope curve of the audio signal reaches a predetermined minimum value, the changing of the recording current for the recording of the video signal is ended and the last value of the recording current is stored for the following recording process. Recording systems in which video and audio signals are stored in tape layers of different depth. <IMAGE>

Title: Device for adjusting the throttle valve of a mixture-forming device for internal combustion engines
Inventor: HULLMANN MATTHIAS
IPC: F02D41/24
Filed: 1988-11-03
Abstract: Known adjusting devices prevent load cycle knocking produced by too rapid opening of the throttle valve, but do not take account of the rate of opening in addition to the opening angle. The new adjusting device avoids this disadvantage. For overcoming the said disadvantage the adjusting device according to the invention has the characteristic that the throttle valve adjustment is performed by way of a servo motor or stepping motor independently of the arbitrary adjustment by the accelerator pedal, which motor actuates a limiting lever by way of a control module as a function of the performance characteristics. Adjusting devices of this type have applications in engine and motor vehicle construction.
