Title: Carbonisation or gasification of oxidised coal dust - using coke dust to preheat the coal for oxidn.
Inventor: SCHUSTER ERNST DIPL ING DR ING
IPC: C10J3/46
Filed: 1977-04-09
Abstract: In the rapid carbonisation and/or gasification of pulverised coking coal after rapid preoxidation of the coal, the pulverised coal is heated to the preoxidation temp. (T1) by (a) mixing with hot coke dust so that the coal particles are heated to a temp. close to T1 by direct heat exchange, and (b) contacting the coal/coke mixt. with the preheated oxidising agent to bring the temp to T1. The coke temp. is pref. sufficient to give the required temp. increase when 1 kg of coke is used per kg. of coal. If its temp. is not sufficient, the coke can be heated by partial combustion before mixing with the coal. The coal can be preheated with coke produced in the carbonisation and/or gasification process.

Title: Glow discharge lamp for spectral analysis - has light intensity increased by producing axial magnetic field in discharge space using toroidal magnet
Inventor: GRIMM WERNER DR
IPC: G01J3/10
Filed: 1978-09-23
Abstract: The discharge space (3: is closed at the cathode end by an electrically conducting disc (8) at cathode potential. A toroidal permanent magnet (32) magnetised axially is used to produce the magnetic field that increase light intensity. A controllable electromagnet is coaxial with the permanent magnet. The permanent magnet is inside the hollow cylindrical anode (1) and is made of a cobalt/rare-earth compound. A flux guide (4, 5) is used to concentrate the magnetic field in the discharge space and consists of a first pole ring (4) mounted on the cathode-end of the permanent magnet and a second pole ring (5) mounted on the anode-end of the magnet (i.e. the end away from the cathode). The axial holes in both pole rings taper inwards in passing out away from the magnet. The discharge lamp is for qualitative and quantitative spectral analysis. The ions striking the sample being analysed (solid, liquid or gas) are only slightly affected by the magnetic field because of their large mass. Nevertheless the increase in ion energy is sufficient to increase sample degradation (solid in or on the disc (8)) and thereby allow the pressure to be reduced from 80001200 Pa to e.g. 130-530 Pa.

Patent DE-2918087-A1 (DE)
Title: Recording and reproduction of video data - using digital, phase modulated and amplitude modulated signals with modulated laser beams carrying additional information
Inventor: ROESS DIETER DIPL PHYS DR RER
IPC: G11B7/13
Filed: 1979-05-04
Abstract: To avoid the necessary summation and subsequent decoding of contrast and colour information for video recording, laser beams are modulated to carry the additional information. The main contrast information provides one of three discrete inputs to the video recorder. After analogue to digital conversion it switches five laser beams to record a five bit code on tape in the form of perforations. The second analogue signal deflects the five beams in line with tape movement and the third analogue signal amplitude-modulates the five beams. This has the effect of altering the width of the beams. Five laser beams are again used for reproduction. They are sensed by photodiodes. The three sources of information are recovered in the form of digital, pulse phase modulated and pulse amplitude modulated signals respectively.
