Title: Method and arrangement for controlling the drying of tobacco
Inventor: WOCHNOWSKI WALDEMAR
IPC: F26B25/22
Filed: 1984-11-03
Abstract: The invention relates to a method and arrangement for controlling the drying of tobacco to a constant ultimate moisture content and ultimate temperature in a drum dryer with controllable wall heating and hot air supply. At the same time, both the ultimate moisture content and the ultimate temperature of the tobacco are detected. The wall heater of the dryer is controlled as a function of a measurement signal corresponding to the ultimate moisture content, whilst the supply of steam into the interior of the drum dryer is controlled as a function of a measurement signal corresponding to the ultimate temperature of the tobacco, in such a way that if the ultimate temperature is too low the supply of steam is increased and if the ultimate temperature is too high it is decreased. The drying power of the wall heater is increased or decreased by charging the air with steam to a greater or lesser extent, which results in the temperature being influenced. <IMAGE>

Title: Electrical drying apparatus for fruit, vegetables or suchlike drying material, especially for domestic use
Inventor: ALBRECHT HANS-PETER
IPC: A47J39/00
Filed: 1986-01-14
Abstract: An electrical drying apparatus, with a fan arranged centrally in a housing and with a heating device, is proposed, there being connected to the housing rack floors which can be stacked one above the other and receive the drying material and through which a generated hot-air stream is guided as far as outlet orifices. The passage cross-section of all the outlet orifices is smaller than that of the inlet orifices, in such a way that there prevails inside the housing and the rack floors an at least slight overpressure, by means of which the drying material of all the rack floors is subjected uniformly to the hot-air stream. Inner channels of the rack floors form a central air channel with an axial build-up cushion, from which the rack floors, connected in parallel, are fed uniformly with hot air radially from the inside outwards. This results in a uniform drying operation in all the rack floors, along with a substantially reduced drying time.

Patent DE-3621200-A1 (DE)
Title: Protection module for telecommunications installations
Inventor: RUDOLF HANS-WERNER DR RER NAT
IPC: H02H9/04
Filed: 1986-06-25
Abstract: The protection module consists of a PTC thermistor (PTC) which is inserted into a wire on a subscriber line as a series element, and of a thyristor diode (TY) which is connected between the wire and earth as a parallel element. These two elements are closely thermally coupled to one another. If unacceptable overvoltages occur in the subscriber line, a current flows through the thyristor diode (TY) which is thus heated and heats the PTC thermistor (PTC). In consequence its resistance increases, as a result of which the overvoltage is limited. Since the protection module is not damaged, there is no need to replace damaged components. <IMAGE>
