Title: Dust separator/neutralizer with charged wash liquor - venturi scrubber with charged and uncharged sprays gives larger droplets and better particle agglomeration
Inventor: HOELTER HEINZ
IPC: B01D47/10
Filed: 1972-09-07
Abstract: Wet dust collector and gas neutraliser uses electrostatically charged wash liquor. The charge separation of the spray liquor is carried out in an insulated charge vessel with an air cushion. Alternatively charged and uncharged water spray zones can be used, and the sprays can have different drop size distributions. Spraying can be carried out in the agglomeration path of a normal wet venturi scrubber. As the agglomerated droplets are electrostatically charged they exert an additional attraction on the dust particles, improving their agglomeration and separation. Higher efficiency permits lower power consumption.

Title: Purifying flue gas through filter bed - using intermittent operation of bed segments while one segment is emptied and another is refilled
Inventor: LACHNIT FRIEDRICH DIPL ING
IPC: F23J15/00
Filed: 1972-12-15
Abstract: A device for purifying flue gases comprises a filter bed contained between two vertical, open-structure walls, the gas flowing in through one wall and out through the other. The filter bed is sub-divided, generally perpendicularly to these outer walls by >=4 intermediate partitions, into segments, moving dampers regulate the supply of flue gas in such a way that two of the segments are always out of operation. With this arrangement, the bed material remains fixed while gas is passing through it, with the result that it is uniformly utilised, i.e. different rates of flow of bed material do not occur, and also there is less prodn. of dust as a result of grinding of the bed material. One non-used segment of the bed is always available for emptying and another for refilling with fresh bed material.

Title: Single stage high reduction gear-box - using one internally and one externally toothed gear on an eccentric
Inventor: MEIER MANFRED
IPC: F16H1/32
Filed: 1973-08-07
Abstract: The drive shaft carries on its end within the gear box, an eccentric which carries an externally toothed wheel which cannot itself rotate relative to the gear box by reason of three equally pitched pins and needle roller bearings. The externally toothed wheel engages within an internally toothed drive gear on an output shaft which is coaxial with the driving shaft. This gives compactness and simple design. The geari is enclosed within a housing which also locates the three stationary pins in the driveside end wall.

Title: Exposure control for aerial reconnaissance camera - with movable ground glass screen to determine the speed to weight ratio
Inventor: FELLE KARL DIPL PHYS
IPC: G03B9/08
Filed: 1974-01-28
Abstract: When calculating the required exposure parameters for aerial photography the ratio of aircraft speed to height has to be determined accurately. In the simple airborne equipment, the operator determines the ratio. A ground glass plate is moved in a reciprocating fashion by belt drive, operated by a variable drive motor. The operator alters the motor speed to stabilise the image on the ground glass screen with fixed reference markings. The final motor speed is then fed into the exposure circuit as a value dependent on the speed/height ratio.
