Patent DE-3608642-A1 (DE)
Title: Circuit arrangement for a microprocessor-controlled remote control system
Inventor: GROSS FRANZ DIPL ING
IPC: H02J3/14
Filed: 1986-03-14
Abstract: In the case of microprocessor-controlled remote control systems, the problem always arose of checking the command loop cyclically or before a switching operation. A check can admittedly be carried out using auxiliary relay contacts, but this is not very reliable. The invention makes possible a check of a two-pole command loop with the aid of a subroutine in the microprocessor, which check consists of an additional circuit in the command loop. This is constructed from two single-pole switches, two resistors, one optocoupler and a plurality of diodes. During one check cycle, the two single-pole switches and the relay contacts in the control loop are controlled by the microprocessor, the optocoupler passing on a defect to the microprocessor and the latter blocking the subsequent switching operation.
Patent DE-3613536-A1 (DE)
Inventor: SCHILLER WOLFGANG DIPL ING
IPC: H03G3/20
Filed: 1986-04-22
Abstract: To regulate a single sideband up converter having a pair of mixer stages (M1, M2), each mixer stage receives control signals to compensate for spurious signals of the mixer components. Part of the radio frequency output signal (RF') from the converter is fed to a down converter (M3). From the resulting down-converted signal, the original intermediate frequency signal (IF) as well as the first harmonic thereof are filtered out as a measure of oscillator and sideband suppression. From these filtered-out signals, control signals for the mixer stages (M1, M2) are obtained.

Title: Fertiliser for controlling the death of the forests and of the plants and for the general conditioning of the soil
Inventor: FISCHER RAINER
IPC: C05D3/00
Filed: 1986-04-26
Abstract: The composition of the fertiliser is designed with the view to providing the soil with important nutrients, on the one hand, but, on the other hand, to fertilising the soil much more by the fact that the natural edaphon is stimulated, protected and included in the fertilising programme. Other aims are to impart a fine, crumbly structure to the soil, thus making it water- and nutrient-retaining, to make organic waste products directly utilisable, to help avoid overdressing (oversupplying with nutrients) more readily, to convert substances which are toxic to the soil into non-toxic forms and to make insoluble nutrients in the soil available to the plants. It is also intended to achieve a higher soil activity by making exchangeable ions available on a large scale. The fertiliser is intended mainly to combat the death of the forests by stimulating the formation of cysteine, which acts as a protection against radiation and as a detoxifying agent by protecting the roots against the action of acid by means of mild alkaline substances and by two highly effective buffer combinations and by facilitating the conduction of high atmospheric electricity.
Patent DE-3614559-A1 (DE)
Title: Conveyor belt
Inventor: RAU HERBERT
IPC: B65G17/42
Filed: 1986-04-29
Abstract: Conveyor belts for unit loads and bulk materials are often subjected to considerable mechanical and chemical loads, which in turn causes wear effects or even breakdowns to occur frequently which, for their part, also lead to downtimes of varying duration of the machines arranged upstream or downstream of the conveyor belt. The object was thus to provide a conveyor belt which is not only altogether more resistant to the aforementioned demands but, on the other hand, also makes it possible, in the event that a breakdown has occurred, for example as a result of inappropriate treatment, simply to replace, in a very short time, those parts of the conveyor belt affected by the breakdown in order thus to restrict the unavoidable downtimes to a minimum. According to the present invention, this object is achieved in a conveyor belt equipped with chains and plates attached thereto in that the plates, which are arranged between two endlessly circulating roller chains, consist of an elastically flexible material, and both ends of these plates are provided in each case with recesses, which are arranged in the end faces of the plates and in which bolts attached to the chains engage, and in that the length of the bolts and the depth of the recesses are dimensioned such that the plates can be inserted, in a condition bent in the manner of an arc, between the bolts of the mutually opposite chains. <IMAGE>

Patent DE-3707285-A1 (DE)
Title: Process for separating off light liquids, predominantly from flowing waters
IPC: B01D17/02
Filed: 1987-03-06
Abstract: The novel process for separating off light liquids from flowing waters is characterised in that the waste water stream is repeatedly subdivided into part-streams and then reunited, in that one of the part-streams flows through a coalescence-promoting mesh with velocity reduction, while another part-stream freely bypasses the mesh and in that the reunification is carried out with exploitation, for coalescence, of the shear forces acting in the turbulent boundary layer. Therefore, additionally to the coalesence proceeding in the meshes as a result of microturbulence, further forces inherent in the flow are used for the coalescence of the dispersed light liquids. The velocity gradient between the two part-streams at reunification leads to increased collision energy, which is converted into coalescence. The flow division can be repeated several times. The division ratio is preferably varied so that each flow filament passes at least once into a microturbulence zone.
Patent DE-3710033-A1 (DE)
Title: Batch-type continuous-flow washing machine and process for producing it
IPC: D06F31/00
Filed: 1987-03-27
Abstract: In a continuously working batch-type continuous-flow washing machine, a multiplicity of annular sliding bearings is provided for separating the various washing fluids between the outer drum and inner drum. These annular sliding bearings not only prevent an intermixing of the washing fluids in the interspace between the outer drum and inner drum, but at the same time serve for supporting the inner drum which otherwise is mounted at the entry end and exit end. In the production of the batch-type continuous-flow washing machine, rings placed with oversize onto the inner drum and being parts of the annular sliding bearings are lathe-turned to size by a lathe chisel which is fastened (indirectly) to the machine frame itself. During lathe-turning, the inner drum is rotated by the drive motor of the batch-type continuous-flow washing machine (Figure 2). <IMAGE>

Title: Method and device for measuring the slip of asynchronous motors
Inventor: MAIKRANZ MANFRED DIPL ING
IPC: G01R31/34
Filed: 1987-07-10
Abstract: To measure the slip of asynchronous motors and in order to monitor by this means the operating state of these motors, mainly used in underground mining, the frequency of the rotor current is determined by detecting the stray magnetic field outside the motor case and the frequency signal is processed and, depending on the application, reproduced and evaluated together with the voltage measured across the motor connection. This method is implemented by means of a device which consists of a sensor which is mounted mechanically protected on the outside of the motor housing, and a measurement value processor which, depending on the use, is provided with an output interface which provides for a connection to an LCD display, a digital/analog convertor or a bit-parallel output. The simple rugged measurement value detection and the appropriate evaluation of the squarewave pulses of the frequency signal determined are advantageous. <IMAGE>

Title: Cutting charge
Inventor: SCHOLLES HERBERT DIPL PHYS DR
IPC: F42B1/028
Filed: 1987-09-30
Abstract: The invention relates to a cutting charge for cutting through flat items such as bridge supports, building elements or chains. The jet-forming liner normally consists of roof-shaped metal cladding, having planar symmetry, of a corresponding recess in the explosive charge. During detonation, the apex of the roof of the liner flows into the rearward ram of the jet which is formed and does not contribute to the cutting power. In the design of the cutting charge (100) according to the invention, the upper part of the liner (25) which does not contribute to the jet is constructed to be shortened; the upper ends of the liner (25) are in this case connected to one another by means of a gas-tight metallic plate (28) which acts as a fume trap. In consequence, undesirable fume propagation is prevented and a required cutting power is achieved with reduced charge masses and a reduced structural height. <IMAGE>
