Title: Aircraft navigation data determining system - uses logic decision stage in conjunction with sensor and radar measuring unit over terrain having low height profile
Inventor: FRYEN JUERGEN DIPL ING
IPC: G01C21/00
Filed: 1980-05-02
Abstract: The representative structure data of the surface of the land which is being flown over are picked up with the help of a sensor pointing in the direction of the height measurement. This sensor is an infra red point sensor or radiometer, whose one-dimensional signal output controls a processing stage giving out the structure data. The height measurement takes place via a height measuring device e.g. a radar height measuring device, whose output is fed to a mixer stage, via a processing stage. The structure data coming from the associated processing stage are also fed to the mixer stage and then on to a logic decision element, to which the output from the mixer stage is also fed. The logic decision element produces a command when the height data represent an insufficient height significance, and feeds this to a store containing the actual heights and structures of the region. The combined data are then fed to a data connection system (6), and the navigation system, producing a satisfactory result when the height data areno longer sufficiently significant.

Title: Paraffin atomiser for candle mfr. - with paraffin jet blown across water mist and air stream
IPC: C11C5/02
Filed: 1980-06-27
Abstract: Powder of paraffin or similar material for the mfr. of candles is produced by spraying liq. paraffin or wax into the air flow of an enclosed space where the atomised particles are cooled. The atomisation is pref. directed into a water mist which moves across or opposite to the direction of the liq. paraffin spray. The deposited paraffin particles finally pass through a drying operation. This raises the output considerably and reduces the energy consumption. The egress of any fine paraffin powder into the environment is prevented.

Filed: 1980-09-24
Abstract: A pneumatic back-up unit enables disturbance-free changeover from automatic to manual operation of a pneumatic control station. The hand control pressure always adopts the same value as set before the air supply failure and the follow-up device starts simply and reliably following a failure. A counter pressure chamber with an air inlet contg. a control element is connected to an operating pressure chamber in the form of a bellows. A rod attached to the bellows acts on the counter pressure chamber via a spring and is connected to a position lever with a manual setting control. An elastic coupling transfers force from the position lever (24) to the rod (13) against the counter pressure chamber (3) expansion direction. A lug (20) enables the position lever to transfer force to the rod in the expansion direction of the counter pressure chamber.

Title: Process for preparing calcium sulphate hemihydrate
Inventor: HEYN KLAUS DIPL PHYS DR
IPC: B01D53/50
Filed: 1981-05-18
Abstract: In a known process for preparing calcium sulphate hemihydrate, especially  alpha -hemihydrate, from flue gas of furnaces, the flue gas is dedusted at least partially and scrubbed with a calcium-containing scrubbing liquid. The calcium sulphite formed is oxidised to give calcium sulphate dihydrate. In order to remove the chlorides introduced via the coal, the dihydrate, prior to conversion into the calcium hemihydrate, is washed and centrifuged. Wash-centrifuging requires quite complex equipment. In order to simplify the process it is proposed, according to the invention, that the calcium sulphate dihydrate produced be converted in the oxidised scrubbing liquid or part thereof into calcium sulphate hemihydrate without first removing the chloride fractions. The  alpha -hemihydrate obtained by recrystallisation and the  beta -hemihydrate obtained by calcination have better properties, in spite of their high chloride percentage, than the previously aimed-for low-chloride hemihydrates. <IMAGE>
