Title: Portable air purifier comprising open-topped washing vessel - with air inlet pipe and baffle plates to generate spray
Inventor: KLOESTERS ALBERT
IPC: B01D47/02
Filed: 1978-05-27
Abstract: Appts. for washing polluted air consists of an open-topped vessel into which a vertical pipe with a very large bottom flange or plate projecting radially from its lower end is inserted. this bottom plate adopts a position 5-10 mm above the bottom of the vessel. Further up the vessel, 10-30 mm above the bottom, an inward-projecting ring fixed to the wall of the vessel constitutes a baffle plate. In operation, polluted air from a room, for example, is forced downwards through the vertical pipe and thus discharges into the vessel, which contains washing liquid; thus a bubbling action takes place, resulting in a large number of very fine washing droplets; the washed air escapes upwards through the open top of the vessel. Used in any place, such as a room or workshop, where polluted air needs to be purified.

Title: Measurement of soot in diesel engine exhausts - using filter paper and monitoring with a light beam followed by digital monitoring system
Inventor: ABELE KLAUS
IPC: H03M1/00
Filed: 1978-08-08
Abstract: The soot content of diesel exhausts is monitored by passing the gas through a filter paper. The paper is than checked by a light beam reflecting onto a photo-sensitive cell. This generates an electrical signal. This signals is then compared to a standard in an electronic system. An oscillator generates a signal which increases in intensity with time. This is added to the signal which is proportional to the soot on the paper. When the sum of these 2 reaches a present value, a flip flop is turned over which in effect triggers the timer. This tine is proportional to the amt. of soot. Used for measuring soot in diesel engine exhausts. Read off errors are eliminated because the read out is in digital form from the counter.
