Title: Process for decreasing the energy consumption during pressing of mixed feeds
Inventor: FISCHER HERBERT DIPL ING
IPC: A23K40/20
Filed: 1986-11-04
Abstract: The invention relates to a process for decreasing the energy consumption in the process for production of pelleted mixed feeds. The aim of the invention is to use the waste energy arising during pressing of mixed feeds for preconditioning the feed mixture and to achieve a high pellet quality. For this purpose the object to be achieved is a direct return of moisture and heat from the exhaust air of the pellet cooler to the cold feed mixture, and specific cooling and drying of the pellets. According to the invention the object is achieved in that the pellets are cooled in a pellet cooler in such a way that a maximum heating and moistening of the cooling air occurs. This cooling air is metered as heat exchange medium into a heat exchanger and flows through the feed mixture. The feed mixture heated and moistened in this process passes into a conditioner, is brought to the optimum temperature and moisture content for the pressing operation and then fed to the feed press. After the further temperature increase, produced by the pressing operation, of the feed mix and thus the pellets, these must be brought, in the downstream pellet cooler, to the temperature and moisture content necessary for storability, the process proceeding further as described above. <IMAGE>

Patent DE-3720882-A1 (DE)
Inventor: SCHULZE KLAUS DR ING
IPC: G10L15/00
Filed: 1987-06-24
Abstract: For the automatic recognition of signal sequences, such as for example speech signals and/or music signals, in each case envelope curves (rectifier 3) are formed from predetermined signals and from signals to be examined and these envelope curves are then band-limited to a narrow, low frequency range (e.g. 2 to 50 Hz). Timing excerpts (approx. 1.7 sec.) are if appropriate stored in a memory (6) as "masks" after digitalisation. When monitoring transmissions, the band-limited envelope curve signals of the signals to be examined are then buffered in a second memory (7) in sections of equal length (of approx. 1.7 sec. in length). Within the period between the arrival of two successive signals to be examined the contents of the buffer (7) are then compared (comparator 8) with all the masks of the first memory (6), a detection signal being generated in the case of a predetermined degree (e.g. 95%) of correspondence.

Patent DE-3727996-A1 (DE)
Title: Method and device for suppressing unacceptable attempts to turn off power semiconductors which can be switched off
Inventor: STEIMEL ANDREAS DR
IPC: H02M7/515
Filed: 1987-08-22
Abstract: The method for suppressing unacceptable attempts to turn off power semiconductors which can be switched off prevents an anode current being switched off in the case of gate turn off thyristors (V1...V6), when said anode current is greater than the maximum anode current (iAmax) which can be switched. To this end, the instantaneous anode current (iAO) of the semiconductor and the time derivative of the instantaneous anode current (diAO/dt) are detected. The time derivative of the anode current is multiplied by the maximum switch-off delay time. The two variables are added and compared with the maximum anode current (iAmax) which can be switched. The turn-off command is suppressed if the measurement variable (M(t0)) formed reaches or exceeds the maximum anode current (iAmax) which can be switched. The instantaneous load current (iL) can also be used instead of the instantaneous anode current (iAO). <IMAGE>
