Title: Method of measuring the moisture content of materials and device for this purpose
Inventor: RICHRATH RALF DIPL ING
IPC: G01N27/04
Filed: 1982-01-19
Abstract: In a method of measuring the moisture content of materials, a resistance of the material is determined by measuring probes and fed into a computer unit which converts this input value into a suitable output value for indicating the moisture content. The object is to modify the method, in conjunction with a suitable device, so that it can be applied to a multiplicity of different materials and yields very accurate measurement results. To this end, it is proposed to determine the output value in the computer unit by a material-specific mathematical function whose coefficients are automatically determined by the computer unit on the basis of specified measurement values to be fed in which are made up at least of different moisture values for the material. A device is used for this purpose whose computer unit comprises a microprocessor for determining a material-specific mathematical function from the specified measurement values fed in.

Patent DE-3239240-A1 (DE)
Title: Method for determining gun sites
Inventor: FISCHER JOHANNES DIPL ING
IPC: G01S5/22
Filed: 1982-10-23
Abstract: For acoustically locating guns, at least two measuring crosses of four adjacently arranged microphones are set up at known positions in the terrain. From transit time differences of muzzle reports of the guns at diametrically opposite microphones of each measuring cross, direction-finding angles are calculated and from these the gun sites are determined, taking into consideration the positions of the measuring crosses. To eliminate direction-finding errors due to wind influences on the propagation of the muzzle report from the gun site to the measuring cross, a sound pulse is sent out from the centre of the measuring cross in shooting pauses and the differences in its reception time at the microphones are evaluated for determining wind strength and wind direction. A correction angle is determined for each direction-finding angle from the ratio between wind strength and sound velocity and a difference angle from wind direction and direction-finding angle. For entering the gun sites into a situation map for artillery reconnaissance, the direction between position and gun sites is determined from the difference between the direction- finding angle and the correction angle.

Title: Coke-oven door with coking plate
Inventor: STOG WILHELM DIPL ING
IPC: C10B25/06
Filed: 1982-10-30
Abstract: The coke oven is sealed off from the atmosphere by coke-oven doors. In order to protect the coke-oven door and draw off the liberated gases uniformly and completely in the region of the door and to coke the top region of the cake of coke uniformly, a coking plate consisting of overlapping shields is arranged on the inside of such coke-oven doors. Between the coking plate, which is separated by spacers, and the insulating layer which protects the body of the door, a gas collection space is formed through which the gases can be discharged in such a manner that they give off a part of their heat to the coking plate and thus to the top of the furnace. The insulating layer is protected by a completely closed box from deposits of condensate, and in particular from water in the event of wet cleaning of the door, while the coking plate is designed so as to be inclined towards the inside of the oven for the uniform coking in particular of the lower region of the top of the oven in the case of only a slight output of gas. In this connection, the coking plate or the shields forming it can be inclined in their entirety or else only in their lower part so that the gas collecting channel is in a sort of stack design.
