Title: Method and circuit arrangement for identifying and evaluating the noise component of an intermediate frequency voltage in the receiving part of a radio unit
Inventor: HANSEN JENS DIPL ING
IPC: H04B1/10
Filed: 1982-10-14
Abstract: A method is proposed which serves to identify and evaluate the noise component of an IF voltage in the receiving part of a radio receiver. The method is characterised by the following steps. Noise identification pulses (IR) are formed from the IF voltage (UZF) by means of a noise identification circuit (17). Within a sequence of n consecutive individual cycles (E1...), each individual cycle is divided up into m sub-cycles (T1 ...). In each individual cycle, the sub-cycle with the smallest number of noise detection pulses is identified in a noise identification pulse evaluator (21) downstream from the noise identification circuit (17). The sum of the smallest numbers of individual cycles is then compared with a predetermined number corresponding to a specific noise component. If the sum of the smallest numbers of the individual cycles is greater than the predetermined number, the noise identification pulse evaluator (21) emits a blocking signal (USp). <IMAGE>

Title: Method and device for producing a round cable from a multi-cored flat-ribbon cable
Inventor: HOHMANN HEINZ H DR
IPC: H01B13/26
Filed: 1983-01-05
Abstract: In a method for producing a round cable having a plurality of conductors, a multi-cored flat-ribbon cable (24) is wound onto a mandrel (10) with a uniform distance between its turns. The winding which is formed is continuously displaced towards the free end of the mandrel (10) in the axial direction and is enveloped with a cable sheath before it runs off from the free mandrel end. On its circumference, the mandrel (10) has a helical web (18) into whose turns the flat-ribbon cable (24) is laid. By rotating the mandrel with the winding held fixed, said winding is continuously pushed away from the mandrel (10) in the axial direction. The flat-ribbon cable supply (22) is located on a support (20) which rotates in the same rotation direction and with the same angular speed as the mandrel (10). For a second cable layer, a second cable supply (30) is located on a further support (28), which rotates coaxially about the mandrel (10) and rotates in the opposite rotation direction to the mandrel (10), and at a higher angular speed. The mandrel (10) has an axial channel (40) through which the winding with the sheath around it can be filled with filling means through the mandrel (10), from a filling means station (38), in order to form an elastic cable core. <IMAGE>

Title: Process and apparatus for carrying out chemical or biochemical reactions
Inventor: HOFMANN ALBERT DR
IPC: B01J10/00
Filed: 1983-11-02
Abstract: The invention relates to a process for carrying out chemical or biochemical reactions while a liquid and optionally a gas is mixed with a liquid reaction medium, according to the principle of a forced-circulation reactor. In order to be able to carry out such a process on an industrial scale and without an adverse effect on the specific energy input or the flow conditions, it is proposed to divide the liquid or the gas into several part streams and to inject these through nozzles into several channels 9 running parallel to one another, at least one part stream being introduced in each channel 9. The mixture emerging from each channel 9 is deflected, combined with mixture emerging from neighbouring channels 9 and returned, via intermediate spaces 10 between the channels 9 and in counter-flow to the flow direction within the channels 9, to one of the nozzle injection sites, which results in a circulation around each channel wall 2. <IMAGE>

Title: Device for setting differential pressures with high precision
Inventor: SUNKE LOTHAR DIPL ING
IPC: G01L27/00
Filed: 1984-02-09
Abstract: The final inspection and testing and quality assurance of pressure-measuring instruments such as pressure sensors and pressure transducers require devices that are suitable for use in automatic test stands and are intended for rapid and high-precision setting of differential pressures ( DELTA p), have a wide setting range, and also ensure high setting accuracies in the region of low differential pressures. For this purpose, two pressure dividers (DT1, DT2) are connected to one another on the feed side and blow-off side to form a pneumatic bridge circuit (BS), in the diagonal branch (BD) of which the specimen (P), which can be connected in parallel with a reference pressure-measuring instrument (RD), is subjected to the differential pressure ( DELTA p), which can be adjusted as the difference of the cascade pressures (px, pr) of the two pressure dividers (DT1, DT2). In this case, the cascade pressure (px, pr) of at least one pressure divider (DT1, DT2) must be variable. The setting of the differential pressure ( DELTA p) is preferably undertaken via adjustable restrictors (NV1, NV2, NV3, NV4) of the two pressure dividers (DT1, DT2). <IMAGE>
Patent DE-3404979-A1 (DE)
Title: Drying by means of vibration
IPC: F26B5/02
Filed: 1984-02-11
Abstract: It is known that many substances form a solid layer on the outside during drying, so that the moisture enclosed on the inside cannot escape, or can only slowly escape, to the outside. To prevent this, the material to be dried must be kept in motion during drying. This motion must be very rapid and therefore follow a short back and forth path with rapid vibrations. However, if such vibrations are to be successful, they must change their direction, and the material to be dried must therefore intermittently vibrate horizontally and vertically; in many cases the material to be dried would nevertheless become solid if the rhythm of the vibration were not varied. Many substances need, during drying, a diffuse rhythm of the horizontal and vertical vibration, while other substances require a harmonic trend for rapid drying. The rhythm of both directions of vibration and further other substances must alternately vibrate harmonically and then vibrate non-uniformly and diffusely. For each substance to be dried, its own program of the vibratory drying can be set up and stored in a computer, and the vibratory drying can then be controlled by the computer as desired.

Title: Electrically driven air humidifier according to the evaporation principle
IPC: F24F6/04
Filed: 1984-03-16
Abstract: Electrically driven air humidifier according to the evaporation principle with a removable water container and a removable hood which are erected on a basic shell. The hood is provided with air inlet openings and designed in such a manner that it bears all the electric parts of the air humidifier. Fastened on the inner wall of the hood is a collar which serves as air duct for the air flowing in through the air inlet openings. Arranged completely or partially inside this collar is an electric motor which drives a fan. The fan draws the air through the air inlet openings and blows it towards a moistened evaporation mat which is partially immersed in a water bath and becomes saturated automatically by its own capillary action. The air is humidifed by the evaporation mat and blown out of the device. The evaporation mat is accommodated, in relation to its width and length, in a lying manner inside the basic shell. The surface measure of its upwardly facing side corresponds at least to the horizontal cross-section of the collar at its narrowest passage point.

Title: Mounted appliance for the working and fertilisation of forest soils
Inventor: MEINBERG KARL
IPC: A01B49/06
Filed: 1984-08-28
Abstract: The invention relates to an appliance for breaking up the soil on forest surfaces, with the possibility of simultaneously discharging fertiliser in a controlled manner into the broken-up strips produced. The appliance can be mounted on any forestry or agricultural tractor having the necessary traction force by means of the standardised three-point suspension (1 + 2). The soil is broken up by smooth-edge plate discs (5) which peel off the layer of humus in strips from the mineral soil. The depth and width of the broken-up strips can be adjusted. The mounting frame (3) makes it possible to mount a fertiliser spreader (7) on top. This introduces the fertiliser in a controlled manner into the broken-up strips produced via a distributor head (9) and hoses (10). The appliance is used to initiate or assist natural regeneration under beech, spruce or other types of tree. Moreover, when there is a change in the types of tree, sowing or planting in the broken-up strips can be carried out even under the cover of the old wood. <IMAGE>
