Patent DE-2649178-A1 (DE)
Inventor: KAELIN JOSEPH RICHARD
IPC: C02F11/13
Filed: 1976-10-28
Abstract: In order to reduce the energy consumption for composting sludge, in a wet sludge aeration vessel (13), the temperature of the material is prevented from decreasing below the reaction temperature required for aerobic thermophilic degradation. For this purpose, the wet sludge to be treated, having a dry matter content of from 3 to 25%, is heated with the aid of a heat exchanger unit (10) by at least 10 DEG C to at least 25 DEG C, dewatered and passed to a heat-insulated wet sludge aeration vessel (13). In the latter, with the aid of the heat produced during the biological conversion process, temperatures of 64 to 72 DEG C are achieved. The hot sludge pasteurised in the wet sludge aeration vessel (13), for the transfer of heat to the freshly delivered wet sludge flowing through the heat exchanger unit (10), is allowed to flow without direct contact with the latter through the heat exchanger unit. After dewatering the biologically treated wet sludge by a dewatering apparatus (3) to 35% dry matter content, this sludge is aerated in an aeration reactor (46) and subjected to a final composting, in order to obtain a sanitary humus-like soil substance containing soil bacteria. <IMAGE>

Title: Counterflow gas cooling heat exchanger - admitting cooling water at various levels mixed with hot water side stream at bottom level
Inventor: BIRKNER ANDREAS
IPC: C10B43/14
Filed: 1977-01-18
Abstract: In an indirect cooling process of gases, e.g. of coke oven gas, with heat exchangers the cooling water rises in the heat exchanger from the bottom upwards while the coke oven gas descends in counterflow to it. The cooling water is split into several side streams which are admitted at different heights to the heat exchanger. The side stream which enters at the bottom end receives an admixture of a side stream of the hot water which leaves the heat exchanger. This preheats the efluent water enough to prevent the deposition of tar and naphthalene which tend to cause clogging. The amount of recycled hot water is small enough to require pumps of moderate capacity.

Title: Arc welding using consumable electrode wire - and two auxiliary power supplies to assist start up and switching off
Inventor: HESSE GUENTER
IPC: B23K9/067
Filed: 1977-05-09
Abstract: Starting and switching off are controlled in arc welding using consumable electrode wire, pref. with inert gas, and esp. to improve striking of the arc while the speed of wire feed is reduced; the speed is then raised for welding. The rate of current increase may also be raised by bridging over an inductance during striking and/or increasing the idling voltage via an auxiliary power source with idling voltage above 60V. During switch off, the build up of material on the end of the wire is reduced by changing from a working characteristic Y2(I2) of the welding current to another characteristic U2'(I2) so the idling voltage is pref. =25V. The pref. welding appts. includes main and auxiliary current supply units, and an auxiliary unit for striking the arc, plus adjusting potentiometers. Provides accurate control of start up and switch off, so welding defects are avoided.
