Title: Continuous determn. of carbon di:oxide and soot in flue gas - by filtering and forcing gas into indicator soln., prevents contamination and poor absorption
Inventor: KONETH ERNST
IPC: G01N33/00
Filed: 1979-12-17
Abstract: Continuous determn. of CO2 in flue gas, using a CO2 indicator soln. (I) is combined with a soot count by forcing gas, filtered for the soot count, into an indicator vessel partially filled with (I). Filtering out the soot before passing the gas into (I) prevents contamination with soot particles and oily deposits, which are very detrimental to the determn. of CO2. Also, the gas is forced into (I) at a rate of min. 10 m/s. which eliminates the need to agitate (I) to ensure absorption. A controllable gas deflector block is placed in the test equipment after a suction and compression pump on the gas pipe which in one position guides the gas into the indicator vessel and in its second position guides the gas not into (I) but directly to the outside.

Title: Coke oven coal prodn. - by compacting coking coal
Inventor: KELLER WESSEL HANS DR ING
IPC: C10B57/04
Filed: 1980-02-23
Abstract: Coal charge for coke ovens is produced by compacting coking coal, partic. coking coal difficult to carbonise, by compressing into slabs in the roller ring of a smooth roller press. The slabs pref. have breaking score-lines so that they can be broken up to a predetermined piece size after cooling. Dust-like constituents are removed from the coal by air separation and/or screening. The coal may consist of a mixture of broken slabs and a portion of undersize and/or uncompacted coking coal. The mixture ratios are 40-50%(pref. about 50%) slabs and 20-60% (pref about 50%) breeze and/or undersize and/or uncompacted coking coal.. The invention provides coke oven coal of the greatest possible density and bulk density in order to favourably influence both the strength of the coke and the coking time. Also, as the roller surfaces do not contact each other the wear on the rollers is reduced.
Patent DE-3011647-A1 (DE)
Title: Fuel pressure regulator for fuel injection system - is sensitive to engine temp. as measured by resistance detector element
Inventor: MAISCH WOLFGANG DIPL ING DR
IPC: F02D41/02
Filed: 1980-03-26
Abstract: The circuit employs electrical heating of an expanding element to mechanically regulate the fuel pressure fed to the injectors. The circuit is free of influence from engine vibration, and replaces bimetal strip controllers. A positive temp. coefficient resistor (14) is used to heat the expanding element. The current flow in the resistor, and hence the heat output, is regulated by a negative temp. coefficient resistor (19) mounted on the engine block. Depending upon circuit configuration, the controller can be active at starting or continuously. Where employed for starting, the normal current flow is interrupted by a contact (6) on the ignition switch, but a transistor circuit (17,18) remains permanently connected. The NTC resistor (19) determines the transistor base current and sets conduction to give the heating required for the detected temp. The circuit ensures that, hot or cold, the fuel pressure is optimised.

Title: Insert at top of mineral wet classification tank - forming multiple overflow edges for lighter fraction suspension
IPC: B03B5/62
Filed: 1980-07-18
Abstract: Wet classification of suspensions of solids with a range of particle sizes is effected by a tank having a central feed pipe reaching close to its base where coarse particles settle for removal. The lighter particles are carried to the tank surface, which is divided into a number of sub-surfaces by a generally conical insert with flanged inner and outer flanges in one horizontal plane. The insert is penetrated by radial rows of inclined tubes all ending in a common horizontal plane slightly below the previous plane. The flanged insert edges and the multiple tube edges all act as overflow weirs, delivering the suspension to an external exit. The insert may be split into two mating halves. Used for treating gravel, sand and like minerals. The greatly increased overflow edges improve efficiency, since the normal flow rate increase near the tank wall is prevented, providing a uniform laminar flow profile with minimised friction losses and no turbulence. The small subsurfaces are protected from wind, waves and vibration.
