Title: Tunable antenna
Inventor: SCHNEIDER REINHARD
IPC: H01Q11/14
Filed: 1986-12-12
Abstract: The tunable antenna (20) has a resonant circuit (31). Its dimensions can be varied by means of a slide (22) which has a lateral connection (27). For this purpose, the lateral connection is passed via conductors (23.1, 23.2) which are routed at a distance from one another. At least in regions, the conductors (23.1, 23.2) are designed to converge (A2<-A1) in the direction of resonance for shorter wavelengths. Their cross-section reduces in a corresponding manner in the direction of convergence in order to maintain the desired characteristic impedance in the respective tuning band. In consequence, the adjustable wavelength band can be considerably enlarged and, in particular, the adjustment accuracy for short wavelengths can be considerably improved. A multiplicity of auxiliary measures and auxiliary devices as well as peripheral devices and measures matched to scientific experimentation purposes are described and drawn. <IMAGE>

Patent DE-3715030-A1 (DE)
Title: Heater elements and pipes of glass or ceramic
Inventor: CHUDOBA CHRISTIAN
IPC: F28F21/00
Filed: 1987-05-06
Abstract: The known heater elements of steel are very liable to rust. Consequently they do not have a long service life and frequently require repairs. The rust also reduces the heating capacity and requires a higher energy consumption. In order to eliminate these disadvantages, heater elements and pipelines have been made from a resistant glass composition. A dye substance is mixed into the glass composition so that the heater elements never have to be painted. The connections are welded or glued. The necessary threads are integrally formed or milled. It does not matter whether the heating elements involve flat, ribbed or pipe heating elements. Glass heating elements as well as ceramic heating elements have long service lives.

Title: Method and circuit arrangement for monitoring track sections in railway systems
Inventor: FRICKE HANS PROF DR ING
IPC: B61L1/18
Filed: 1987-09-24
Abstract: The method for monitoring track sections in railway systems with or without insulated rail joints provides for a direct or alternating voltage to be supplied and for the existing voltage to be tapped at the end of the track section, the steepness (dUG/dt) of changes in the direct voltage (UG) with step-shaped timing being measured at the end of the respective section and being compared with a predetermined, maximum possible voltage change per time unit as a result of the change in ballast. In the case of a negative step which is steeper than in the case of a maximum change in ballast, the occupied state is indicated. The value of the amplitude of the track voltage in the occupied state is measured and the display is stored and the clear state is not indicated until after a positive step which is steeper than in the case of a maximum change in ballast and an amplitude change which is greater than 20% of the amplitude in the occupied state and subsequent constancy of the voltage value increased by the step.

Title: Production of nitric acid with associated process for cold generation
Inventor: FUDERER ANDRIJA DR ING
IPC: C01B21/26
Filed: 1988-03-03
Abstract: Ammonia is vaporised with the generation of cold and the ammonia vapour is absorbed in aqueous solution. The enriched ammonia solution is contacted with oxidation gas or air, with ammonia being desorbed from the solution and additional cold being generated. The mixture of air and ammonia obtained is used for the production of nitric acid. The air contains about 0.03 mol % of carbon dioxide. To keep the content of ammonium carbonate in the solution low, the carbon dioxide and the ammonia are driven out of a part of the solution at elevated temperature. Preferably the air is first brought into contact with a smaller part of the solution at lower temperature, with most of the carbon dioxide being absorbed in this solution. Subsequently, the carbon dioxide is driven out of this solution at elevated temperature.
Patent DE-3806934-A1 (DE)
Title: Foam-gas generator
Inventor: GEIER-HENNINGER KURT
IPC: F01N3/04
Filed: 1988-03-03
Abstract: The possibility of optimal exhaust gas scrubbing is ensured by this process. The method of driving the air vane via hot exhaust gases and water injection ensures an exhaust gas pressure drop which could otherwise have a harmful effect on the motor as a result of back pressure. Good mixing of the alkaline volume of water by the water circulation which, as an injection, simultaneously sets the air drive vane in motion and thus sprays the volume of exhaust gas prior to entry into the water bath is a great advantage. The distributor crown with the zigzag notches prevents breakthrough of the exhaust gas air at a point which again would have a negative effect on the exhaust gas scrubber. The foam beater in turn ensures good exhaust gas air incorporation into the alkaline water which in turn ensures good foam production. The foam formation above the water surface binds all very fine particles which would otherwise pollute the environment. The gypsum-soot sludge arising can be disposed of by suction or through the cleaning nozzle. Neutralisation with water turns the carbonate into standard gypsum waste.
