Inventor: LAILACH GUENTER DIPL CHEM DR
IPC: B01D53/86
Filed: 1986-05-16
Abstract: The present invention relates to a process for purifying flue gases, containing sulphur oxides and nitrogen oxides, hydrogen halides and/or dust, by oxidation of sulphur dioxide in the presence of carbonaceous catalysts with the formation of sulphuric acid or sulphates and subsequent reduction of the nitrogen oxides with ammonia in the presence of carbonaceous catalysts with the formation of nitrogen and water.

Title: Device for determining the control precision and the stability of control loops from measurement values and parameters of the control loop
Inventor: MUELLER ULRICH DR ING
IPC: G05B23/02
Filed: 1986-05-28
Abstract: A device determines the values for selectable quality criteria or stability measures from measured signals of a control loop and predeterminable known parameters of the control loop. This can be done once or continuously during the operation of the control loops. Control can be effected both time-discretely and time-continuously. To determine the stability or control precision, the device has identification devices which form models of controller and controlled system. Following switch-over, logic and transformation devices then supply at the output a model which describes the dynamic characteristics of the control loop in such a manner that the stability and control precision are determined from these in an evaluating device and can be indicated or forwarded by means of an output device. The indicated values can be used for adjusting the controller even during the operation of the control system.
Patent DE-3625561-A1 (DE)
Title: Pressure packaging, in particular aerosol can for liquid media
Inventor: KUECKENS ALEXANDER DIPL ING
IPC: C09K3/30
Filed: 1986-07-29
Abstract: In order to promote the use of harmless propellants in aerosol cans, to minimise the supply of propellant required for spraying the liquid medium and to improve the effect of the liquid medium in some cases of application of such aerosol cans, provision is made for the liquid medium to be finely impregnated with CO2 before it is introduced into the pressure container, specifically in a quantity which is at least approximately equal to the natural CO2 absorption capacity of the liquid medium at about 20 DEG C and atmospheric pressure. Consequently, this counteracts absorption of the propellant gas by the liquid medium, significantly increases the effect of body-care media as well as the use of fertilisers or plant protective agents and, at the same time, improves the durability of the liquid medium.

Title: Apparatus for feeding sheet-metal strips into the die space of a press by means of sliding latches
Inventor: HARSCH ERICH
IPC: B21D43/06
Filed: 1987-04-14
Abstract: Apparatus for feeding sheet-metal strips into the die space of a press by means of sliding latches. When resetting the press, the replacement of the latch rails presents considerable difficulties. It is the object of the invention to avoid these difficulties and to automate the conversion to another feed length. To achieve this object, it is proposed here that the apparatus   a) consists of two sliding latches (1 and 2), one of which pushes the sheet-metal strip (7) forwards while the other is running back to the starting position, b) that both latches be driven by a common stepping motor (8) i.e. that the pushing latch be moved forwards and the idle latch be moved backwards by one drive, and c) that a variable-speed gear unit (5), by means of which the spacing of the two latches relative to one another can be adjusted is placed between the drive motor (8) and the linear drive of a latch (10), thus allowing the apparatus to be converted to different strip lengths (8).   <IMAGE>

Title: Process for the low-level desulphurisation of base iron for the production of steel and cast iron
Inventor: BEELE GUENTHER DIPL ING
IPC: C21C1/02
Filed: 1987-07-22
Abstract: In foundry technology, there is a desire for as low as possible a sulphur content of steel or vermicular graphite iron or spheroidal graphite iron. A simple process for the low-level desulphurisation of the starting melts for the production of steel or cast iron is sought. According to the invention, the pre-desulphurised base iron melt is placed in a holding furnace under a gauge pressure of from 1 to 90 mbar and only drawn off after a residence time of some minutes. It has been found that in this way a low-level desulphurisation to values of less than 0.005% of sulphur can be achieved. Production of steel iron and cast iron.

Title: Automatic adjusting device for a disc brake
Inventor: HENDRICH UWE
IPC: F16D65/56
Filed: 1988-01-13
Abstract: The invention starts from an automatic adjusting device for a disc brake, in which two adjusting elements connected to one another by a thread free from self-locking are provided between the brake piston and the mechanical actuating device. The object of the invention is to ensure that, after a certain force has been overcome, the adjusting elements can with certainty move freely relative to one another, thereby avoiding hysteresis in the process of adjustment and ensuring that this movement does not start only in the presence of large braking forces. The invention achieves this by providing one of the adjusting elements with a floating support, allowing the adjusting element to be displaced in the longitudinal direction of the brake cylinder after appropriate frictional forces have been overcome. <IMAGE>

Title: Drinking device for small animals
Inventor: HAIGES ADOLF
IPC: A01K7/06
Filed: 1988-06-16
Abstract: The prior art (DE 3507284 C1, Figure 4) is a device according to the preamble of the laid-open Claim 1, on whose drinking basin the water-line connection stub is rotatably mounted in a frictionally locking manner, the adjustment screw, provided as droplet screw, being screwed into the outer collar of said connection stub. The disadvantage of this arrangement is the rotatability of the connection stub, with the adjustment screw, about its longitudinal axis, with the result that, in the case of an incorrect initial setting or if an adjustment should be required, the screw cannot be reached if the connection stub is in an incorrect rotary position once the device is assembled. The object of the invention is to ensure in a simple manner the desired pivot position of the adjustment screw from the outset, that is to say the rotary position of the water-line connection stub. This object is achieved by the device according to the laid-open Claim 1 with the characterising features that the water-line connection stub (34) is mounted in a rotationally fixed manner on the drinking basin (10) and for this purpose is connected, in the intended fashion, to the basin in a positively locking manner. The advantage of this is the exclusive connectability of the connection stub, and thus of its outer collar with the adjustment screw in a specific pivot position of the same, i.e. in a certain rotary position of the connection stub, to the basin, with the result that the adjustment screw can always be reached. <IMAGE>

In accordance with the desired taste, greater or lesser amounts of the individual ingredients are selected to produce the base mass. Further additions which lead to a rounding-off of taste, are possible, in addition enhancement to achieve a particular component as a "highlight".

Title: Drive for agricultural vehicles
Inventor: KNELL KARL DIPL ING
IPC: B60K17/28
Filed: 1988-09-12
Abstract: In a drive for agricultural vehicles a drive train leading from the engine (1) by way of a drive clutch (2) and a manual shift transmission (3) to the vehicle drive wheels (4) is provided. A power-take-off shaft (5) is also driven by the engine (1) independently of the said drive train. In order to achieve a reduction of the dimensions and the weight of the manual shift transmission (3) despite the comparatively high engine power output, the manual shift transmission (3) is designed for a reduced input torque compared to the maximum engine torque. In addition an overload protection clutch (6), which interrupts the drive train when the said input torque is reached, is fitted in the drive train between the drive clutch (2) and the manual shift transmission (3). A one-way clutch (7) or the like, preventing reversal of the drive train, is directly assigned to the overload protection clutch (6) on the output side. <IMAGE>
