Title: Method and device for measuring distance using air-borne sound
Inventor: WIESE ANDREAS DIPL PHYS DR
IPC: G01B17/00
Filed: 1986-06-28
Abstract: In the method and the device operating using this method for measuring distance by means of air-borne sound, a sound pulse is generated in a sensor and directed onto a reflecting object, and the transit path of the sound, and thus the distance between sensor and object, are determined electrically with the aid of the sound echo pulse. In order to prevent irregularities in the propagation of sound on the transit path, a temporally constant airflow is maintained along the transit path of the sound. For this purpose, there is arranged in a housing of a measuring head a fan which conveys air through an exit opening which is at the same time the exit opening for the sound.

Title: Process for backfilling cavities in underground mining
Inventor: HOELTER HEINZ DIPL ING
IPC: E21F15/00
Filed: 1986-12-27
Abstract: Cavities in underground mining are backfilled with a mixture of rejects and/or tailings and calcium chloride-rich wet and undried raw gypsum, which is mixed beforehand with filter ash or fly ash. By means of enriching the raw gypsum with calcium chloride, the evolution of dust is reduced in a controlled manner, and the crystalline fine-grained raw gypsum structure and the ash produce at the same time a substantially more dense pneumatic backfilling material which thus leads to a more advantageous degree of backfilling. Raw gypsum and filter ash are mixed in a 50:50 ratio and then added to the rejects and/or tailings in a ratio of 20:80.

Abstract: In a multiple computer system, with one computer pair (MC1.1, MC1.2) or triple on the transmitting side and one or more computer pairs (MC2.1, MC2.2) or triples on the receiving side, two computers (MC1.1, MC1.2) in each case transmit data alternately via a single transmission channel, e.g. a telephone line (F), to all individual computers (MC2.1, MC2.2) of a receiving computer pair or triple. There, the received data is tested for matching. If the data agrees, it is recognised. If it does not agree, the computers (MC2.1, MC2.2) which evaluate the data determine from the data whether the fault which has occurred is to be found on the transmitting or receiving side of the system. In the first case, the data is rejected, and in the second case the computers block themselves permanently against evaluation of the data at their input modules (S/P2.1, S/P2.2). At specified time intervals, which are at most equal to the permitted time to discover individual failures for the associated computer pair or triple including its input/output modules (P/S1.1, S/P1.1, P/S1.2, S/P1.2), the individual computers (MC1.2 or MC1.1) of the transmitting computer pair or triple which are in each case not actively involved in the data transmission read the data which is output by the respective active individual computer (MC1.1 or MC1.2) via their input modules (S/P1.2 or SP1.1), and compare it with the data which they have processed themselves ...

Title: Plant for treating a flue gas stream
Inventor: RUETTEN JUERGEN DR
IPC: F23J15/00
Filed: 1988-02-11
Abstract: In known flue gas purification plants, a heat exchanger (3) is assigned to a denitration reactor (5). The inflowing flue gas which has been cooled, eg. by an upstream wet desulphurisation, is reheated in the heat exchanger by heat exchange with the outflowing flue gas. The heat exchanger (3) must be cleaned from time to time. Cooling is necessary prior to cleaning. Only a restricted time is available for the cooling. Rapid cooling is to be made possible by the invention. A cold air feed (19, 20, 21), which can be shut off, opens out into the flue gas duct upstream of the secondary-side inlet of the heat exchanger (3). Downstream of the denitration reactor (5), a duct (26), which can be shut off, is branched off from the flue gas duct. The flue gas duct is fitted with a shut-off means (25) downstream of this branching. The cooling of the heat exchanger (3) is accelerated by a cold air stream which is passed via the secondary side of the heat exchanger (3). The air stream which then flows through the denitration reactor (5) and is heated in the course of this is conducted past the secondary side of the heat exchanger (3) in the bypass. Plants for the desulphurisation and denitration of the flue gases of large-scale furnaces. <IMAGE>
