Title: High-speed carburetter for an otto engine
Inventor: BRANDNER BURKHARD
IPC: F02D9/02
Filed: 1984-09-13
Granted: 1988-09-29
Abstract: A high-velocity carburetor for an Otto engine comprising a slide for changing the cross-section of the suction pipe, a nozzle connection receiving nozzles and a profiled nozzle needle seated on the slide and controlling the cross-section of the nozzle. One object is the precise adjustment of the air admixture and thus an optimum mixture regulation as a function of the most important parameters for the operational conditions. The nozzle connection contains two nozzles, situated coaxially to one another and separated from one another by an intermediate chamber. The intermediate chamber is connected to an outlet channel of a flow control value having a ferromagnetic membrane-like valve plate. The valve plate is operable by two coils opposing each other and being connected to push-pull outputs of a pulse generator with adjustable pulse duty factor. An input channel of the flow control valve is connected with the atmospheric air via an air filter. For the control of the pulse duty factor an address memory is provided which can be addressed by load values, speed values, and temperature values and which contains in the form of a performance characteristic field information values for the pulse duty factor so that the pulse duty factor and thus the air admixture in the intermediate chamber can be adjusted in accordance with said information values.

Abstract: A radio direction finding station for locating lightening strikes has three vertical antenna loops (10, 11, 12) in an equiangular trigonal arrangement. The vertical loops are positioned to minimise magnetic coupling between them and with a fourth horizontal loop (14). Filters (25-28) pass only signals from the loops with frequencies below about 2.6 kHz to eliminate most horizontally polarised components of the received radio waves. The signal from the horizontal loop represents any residual horizontally polarised component and is used in a central control station to correct for residual polarisation error in the measured bearings.

Abstract: A positioning system for racing cars is disclosed, which comprises a vehicle information device mounted in a racing car, with a positioning device for gathering and output of positional data, by means of which the position of the racing car can be fixed and a transmitter for sending the positional data to a control centre. A number of such vehicle information devices, operated in cooperation with a computational device, allow a useful execution of a positioning system, whereby said computational unit calculates the position of each car on the circuit from the transmitted positional data and stored race track data. The position of each of the race cars can be fixed using the virtual map of the race track course, in the form of the race track data and the transmitted positional data, without the need to establish positioning devices at essentially all the points around the race track. A vehicle coming to rest or leaving the race track can also be determined and precisely located without additional requirements.
