Title: Improving heat utilization in a pulp grinding process
IPC: D21B1/18
Filed: 1981-11-13
Abstract: A method of improving the utilization of the heat energy of a process for making groundwood pulp in which wood is ground in a grinding space (3) under an absolute pressure exceeding the atmospheric pressure and heated shower water (G) is fed into the grinding space. Steam (H) is released in a steam separator (11) from the groundwood pulp (A) discharged from the grinding space, and replacement water (E) is added to the shower water for replacing of shower water losses. The amount and the temperature of the replacement water are chosen so that a desired energy distribution is obtained between the heat energy of the steam (H) released in the steam separator and the heat energy of the groundwood pulp (B) discharged from the steam separator. By adjusting the temperature of the groundwood pulp discharged from the grinding space either by means of the amount and/or by means of the temperature of the replacement water added to the pulp, it is possible to adjust the distribution of the heat energy generated in the grinding process between the consumption needs for steam and the consumption needs for warm water. <IMAGE>

Title: Dwell and rest coil current control in IC engine ignition units
Inventor: BODIG BERND
IPC: F02P3/04
Filed: 1984-04-16
Abstract: An ignition unit for internal combustion engines is proposed, having a first threshold switch (15) controlled by the voltage of an inductive angle of rotation transmitter, the make and break threshold values of the switch essentially controlling the current flow time in an ignition coil (32). A second, correspondingly controlled threshold switch (16) having the same make threshold as switch (15) but having a positive break threshold value (Ua2) triggers, on reaching the said threshold value, a time-function element, constructed as a digital counter (39), in which a clock frequency (38) is counted cyclically. On expiration of the hold time of the time-function element, if the first switch has not initiated the spark, the ignition coil current is switched off via a bistable switching stage (40) so as to switch off the rest current. The ignition coil current is switched on again via a logic interconnection circuit (41) if the bistable switching stage (40) is in the switched-off state and at the same time a lower numerical value is reached in the counter (39). This produces a reduction of the dwell angle at low speeds, with the angle of rotation transmitter (10) otherwise functioning normally. Both functions are essentially counter (39). <IMAGE>
