Patent DE-2855509-A1 (DE)
Title: Smelting iron ores without forming deposits on furnace walls - by using mixt. of different iron ores in furnace charge, esp. haematite and magnetite
Inventor: WENZEL WERNER PROF DR ING
IPC: C21B13/00
Filed: 1978-12-22
Abstract: To prevent deposits on the walls of blast furnaces, rotary drum furnaces, or other smelting plant, the charge is made from a mixt. of different iron ores so it has a very low tendency to form deposits during the smelting operation. The charge pref. consists of a mixt. of haematite ore (I) and magnetite ore(II). To obtain the ore mixt. (I, II), part of ore (I) may be pre-reduced to form a ore of type(II); or part of ore(II) may be oxidised to form an ore of type(I). Alternatively a mixt. may be used of ores in which the Fe is in the same oxidn. state but the ores possess a different physical structure and/or different amts. of FeO, CaO, MgO, Al2O3 and/or similar cpds. The invention also prevents the formation of "scaffolds" in blast furnaces.

Title: Mobile VHF radio receiver - has selective, short period attenuator between aerial and limiter stage, attenuating output volume in dependence on transmitter power
Inventor: KUNZ WERNER
IPC: H03G3/14
Filed: 1978-12-22
Abstract: A high frequency input stage, is connected to the mobile radio receiver aerial followed by an intermediate stage, a limiting stage, a demodulator, a low frequency amplifying stage for the loudspeaker for a headset, and a separator for a low-reception transmitter. Between the aerial and the limiter stage is incorporated an attenuation element which can be selectively switched for a short period. The attenuation element is used to reduce an output volume in dependence of the transmitter reception quality, i.e. reducing it considerably with a low-reception transmitter, but only negligibly with a strong-reception one. Pref. the attenuation element has a capacity of 30 dB. It may be incorporated in the hf input stage (14), or may be in the form of a resistor which can be incorporated into the aerial line. Alternately a switch, short circuiting the aerial voltage partly to earth, may be used for this purpose. Other possibilities are specified, e.g. a resitor varying the base biasing voltage of an amplifier transistor.

Title: Transferring mats for chipboard or similar press - onto final accelerating conveyor from spreading conveyor in symmetrical positions for feeding into press
Inventor: ARNOLD DIETER DR
IPC: B27N3/20
Filed: 1980-04-10
Abstract: Separate sections of fleece or mat, consisting of vegetable rs. contg. binding agents such as glue or cement, are deposited from a constant-speed spreader belt (I) onto a further conveyor (II) typically leading to a multistorey hot press. The second conveyor (II) carries the mats on a series of individual trays or plates. These trays are fed by a feed conveyor running at the same speed as the spreader conveyor to a transfer point. On the feed conveyor the trays are overlapped to allow for their excess length over the length of a mat and at the transfer point each mat is deposited centrally on the associated tray and the trays and mats are then transferred to the final conveyor (II). The latter is constructed as an accelerating conveyor. Pref. at the transferring instant, all three conveyors run at the same synchronous speed. After the further conveyor, (II) has received its tray, it then accelerates until it slows down again to receive the next. tray. In this way, trays become more widely spaced apart on the final conveyor (II) but each tray carries its mat centrally about its axis. Each mat is located centrally about the central axis of its transporting tray and is therefore symmetrically placed for feeding into the subsequent multistorey press.
