Title: Speed measuring system for road vehicles - uses ultrasonic transceiver mounted on body to compute speed from Doppler frequency changes
Inventor: BERNER ROLF DIPL PHYS DR
IPC: G01S7/52
Filed: 1980-05-07
Abstract: The speed of the vehicle is measured by a unit (4) containing an ultrasonic transmitter, mounted on the body of the vehicle and emitting ultrasonic energy at the surface of the road, at an angle (alpha) to this surface and in the opposite direction to the direction of travel of the vehicle (1). The measuring unit has a cone shaped tube (25) attached to the transceiver opening, to protect dirt etc. entering. When ultrasonic waves are emitted, part of the diffusely reflected energy from the rough road surface, is picked up by a receiver, and the frequency difference between transmitted and received waves fed to an electronic computer. This calculates the speed of the vehicle, using the customary Doppler effect formula, the result being independent of wheel revolutions. The speed of the vehicle can be displayed digitally and stored as a record for use should the vehicle be involved in an accident.

Patent DE-3100712-A1 (DE)
Title: Underwater burner
Inventor: WALTER ROBERT
IPC: F24H1/10
Filed: 1981-01-13
Abstract: The use of this burner is intended primarily for domestic gas heating systems. The economy and also the degree of efficiency ought to question the construction of distant heating systems. The principle is optimum combustion under high compression with chimney-free removal of the waste gases as an additional heating source. Details for possible production are described as follows: the generation of the more highly compressed air/gas combustion mixture takes place expediently by two identically running differently dimensioned vane-cell compressors. With slow starting, peak pressures cannot arise. To achieve higher pressures in the boiler space, compressed air is introduced from the air compressor into the rising pipe which is closed at the top. By means of safety valve and pressure reducer, any required boiler pressure can be achieved. Via the known air separator, the residual heat of the waste gases can be made useful by means of a tubular heating system leading into the open. As the degree of efficiency can hardly be achieved without soot impairment by other heating installations, a gasification possibility of oil or coal with separation of the aggressive environmentally harmful sulphuric acid would be of interest and economically conceivable.

Title: Underground tank for drinking or service water, comprising large-pipe water chambers, located perpendicularly one on top of the other, and having a meander-shaped outline
Inventor: GEBERT HEINZ ING GRAD
IPC: E03B11/14
Filed: 1981-02-14
Abstract: For the storage of drinking or service water, an underground water tank comprising large pipes is described in the filed patent. Tanks of this type are used, for drinking or service water, in the supply of water to individual objects or in large-scale water-supply systems. The water tank of the application is, unlike the tanks which chiefly comprise solid structures, designed with industrially manufactured large pipes with identical connecting shafts. The flow through the tank is uniform owing to the meander-shaped outline and the tank has no unused areas. One or more water chambers connected in parallel can be erected, and it is also possible to plan and design the tank in one or more structural portions. The construction work permits a relatively small construction area since only prefabricated parts are used. The building pit can be kept small since it is possible to lay the runs of pipe one by one and only the building pit required for a single pipe run thus has to be provided. <IMAGE>

Patent DE-3119211-A1 (DE)
Title: Internal combustion engine operated with gaseous fuel stored in the liquid state
Inventor: BERGMANN HORST
IPC: F02M31/18
Filed: 1981-05-14
Abstract: The invention relates to an internal combustion engine operated with gaseous fuel stored in the liquid state with a fuel vaporiser subjected to heat, from which fuel vapour is fed by way of a spring-loaded, diaphragm-controlled control valve to the cylinders by way of a gas mixer and by way of a throttle valve into the intake line. During the starting phase of an internal combustion engine the pressure of the fuel vapour in the fuel vaporiser is led by way of a solenoid reversing valve to the rear side of the diaphragm of the control valve, as a result of which more vaporised fuel reaches the gas mixer and condensation losses on cold walls in the intake system are compensated for. The reversing valve is connected parallel to the starter circuit. When the internal combustion engine is at operating temperature, a temperature switch opens, so that the reversing valve then remains closed and the control valve can only feed the normal quantity of vaporised fuel to the gas mixer.
