Title: Electronic musical instrument which can be played by means of a resistor or a capacitor
Inventor: JUENGLING HELMUT
IPC: G10H5/00
Filed: 1985-06-10
Abstract: The invention relates to an electronic musical instrument which is manually operated by means of a variable resistor or a capacitor instead of by keys and/or strings. The explanation of all the electronics is omitted for the sake of simplification. Instead of being handled by a resistance network in the control generator, the control voltage or currents of the instrument electronics are handled by only one variable resistor which is connected to an apparatus which allows the current or voltage pick-up (for example (4) in Figure 1) to be rhythmically moved. This also rhythmically changes the value of resistor (1), and also the frequency of the sound, due to the varied control voltages or/and currents. The instruments played by means of a variable capacitor (for example Figure 3) have electronics in which the capacitor is connected into the output of the last VCO and into the input of the mixing adder following. This directly controls the preceding frequencies and makes them manually playable by means of a mechanical arrangement. This makes it possible to adapt or connect to the instrument all home-built designs and many synthesizers, effect devices and other additional electronics found in the market. The instrument has the capability (not shown in the drawing) of accepting all accessory connections as for amplifier, headphone, microphone connections and so forth and ...

Patent DE-3524717-A1 (DE)
Title: Forcing the human body with a mechanical force against media (liquids) in order to exert a positive influence on the body
Inventor: FUEST HEINZ
IPC: A61H9/00
Filed: 1985-07-11
Abstract: Treatment of the human skin and other organs by manual or mechanical massages/vibrations has hitherto been impossible over the entire surface of the human body at the same time and isometrically. Hitherto, it has been common practice to direct all activities toward the human body, whereas although the present method also directs the activities immediately to the body it uses the body itself for the purpose and, in addition, uses a medium for the positive effects on the human body. Mechanical force can be applied in a wide variety of ways. However, the result of greater efficacy of the positive effects on the human body remains unchanged as compared with the previous methods.

Title: Sample chamber for spectroscopic studies on aggressive fluid samples at temperatures of up to 250 DEG C
Inventor: BAUMANN MARKUS DIPL CHEM
IPC: G01N21/09
Filed: 1985-11-02
Abstract: Hitherto, no suitable sample chamber has been available for spectroscopic studies of aggressive fluid samples at temperatures of up to 250 DEG C, as the vessel materials used hitherto, especially quartz, are not inert with respect to alkaline media at elevated temperatures. If a sample container of partially transparent polytetrafluoroethylene is used, spectroscopic studies in the wavelength range of visible light can be carried out even at temperatures of up to 250 DEG C without a drop in the signal level.

Title: Conducting element for electrical current, having relatively reduced heat conduction, preferably for use in thermoelectric devices
Inventor: BOJAK KURT DIPL ING
IPC: H01B5/00
Filed: 1985-11-26
Abstract: In order to reduce the damaging heat flow in conductors for electrical current, conducting elements are combined from harnessed or layered individual conductors each having such a narrow cross-section that the mobility of the particles or grids in the material structure required for heat conduction is limited, while the electron mobility for electrical conduction is not yet adversely affected. Such a construction would be advantageous for the limbs of thermoelectric devices, in order to reduce the heat flow losses, or even as thermal protection in other technical installations.

Patent DE-3608527-A1 (DE)
Title: Tractor vehicle, in particular for agricultural use
Inventor: LELY CORNELIS VAN DER
IPC: B62D7/00
Filed: 1986-03-14
Abstract: The tractor has two driven rear wheels and two steerable front wheels, the track width of the front wheels being hydraulically adjustable. As a result, it is possible for the tractor, depending on the type of work it is being used for, to have four track widths located one next to the other or for the front and rear wheels to run in common track widths. The tractor is constructed in such a way that the ground pressure exerted by the tractor is equal at all four wheels. For this purpose, two drive engines are provided, one engine serving essentially to drive the rear wheels and the other engine serving to drive connected machinery such as for example a circular self-cleaning harrow. If an increased traction force is required, such as for example during ploughing, an additional drive roller which is connected to the tractor at the front can be driven by means of the second engine. As a result of the lightweight design, the uniform distribution of weight and the track width adjustment, the tractor can be used for preparing seed beds and for relatively heavy work such as for example ploughing, even the cultivation of row crops is possible.

Patent DE-3620233-A1 (DE)
Title: Method of identifying workpieces which are in a hot state
Inventor: SCHROEDER MICHAEL DIPL PHYS
IPC: C03C17/06
Filed: 1986-06-16
Abstract: Method of identifying workpieces of glass, ceramic or porcelain which are in a hot state. According to the new method, workpieces which are still in a very hot state can be reliably identified without a thermal or mechanical stress being applied to part of the workpiece. A thin carrier layer about 50 to 1000 nanometers thick, serving as an identification field and consisting of a material which condenses and solidifies on the hot workpiece, especially metal or graphite, is vapour-deposited on the hot workpiece under an inert gas atmosphere and the symbols serving for identification, such as numbers, letters, bars or similar codings, are generated by partial removal of the carrier layer by means of laser beams. The method is particularly suitable for identifying picture tubes, optical glasses and other workpieces of glass, ceramic or porcelain.
Patent DE-3621377-A1 (DE)
Title: Fastening of a covering cap on a substructure, in particular for an electric installation
Inventor: KELAIDITIS KONSTANTIN DR ING
IPC: F16B5/06
Filed: 1986-06-26
Abstract: A fastening of a covering cap (5) of an electric installation on a substructure exhibits a spacer piece (6), which is fastened on the substructure, and a bolt (21) which passes through the covering cap and is fastened on the intermediate piece. The bolt end (25) is pointed and, owing to two opposite incisions, which can not be seen in the Figure belonging to this abstract, is configured as a double hook which, in its latching position, is latched in the spacer piece (6) behind two opposite lugs (16) which can bend out flexibly. Between the two incisions, an edge (26) runs over the bolt end (25), on the central longitudinal section of the bolt (21). The bolt can be demounted by being turned, by means of a screwdriver, through 90 DEG  with respect to the latching position. On mounting, it usually turns of its own accord into the latching position if it is driven in loosely. The punched edge, running over the bolt end, reduces, to the smallest possible extent, the probability of the bolt making contact in the dead centre position and not turning into the latching position. <IMAGE>

Patent DE-3635048-A1 (DE)
Title: 4-Stage flue gas scrubber having integrated heat recovery for small boiler units
Inventor: DOLATA TILO DIPL ING
IPC: B01D53/60
Filed: 1986-10-15
Abstract: The invention serves for purifying the flue gases or exhaust gases and for improving the thermal efficiency of boiler units; predominantly of heating systems of homes and apartment blocks and in industrial, commercial, administration and office buildings. The particular constructional design of the gas scrubber enables the flue gases to be freed from the pollutants SO2, NOx and ash, or for these to be greatly reduced, by a four-stage adsorptive, absorptive and catalytic scrubbing. The gas is uniformly wetted with a scrubbing liquid over the entire flow cross-section in a flue gas intake duct. During the spray absorption, the flue gas temperature is decreased below the water dew point (t < 43@C). The flue gas is then purified in two activated coke layers lying one above the other. In the bottom layer, SO2 is bound by adsorption and NO2 is converted to CO2 and N2. The top activated coke layer is activated by ammonia. Here the NO reacts catalytically with NH3 to form N2 and H2O. The last scrubbing stage (4th stage) provided is again a spray absorption in the flue gas outlet duct. The flue gas is cooled in the flue gas scrubber down to approximately 25-30@C. The total thermal energy released is utilised for preheating the heat transport media (heating water and/or service water). The scrubber is composed completely of plastic. Corrosion problems are thus excluded.
