Title: Highly sensitive immunological detection method - esp. for low mol.wt. pollutants, with extra wash stage between addn. of sample and tracer
Inventor: GROENERT RENATE
IPC: G01N33/53
Filed: 1990-01-12
Abstract: In an immunological detection method, the new feature is that between addn. of sample antigen and tracer, additional washing steps are carried out. Pref. the method can be applied to systems where a radioisotope, enzyme, fluorescent substance or an electronic-signal generating cpd. is used as label. USE/ADVANTAGE - The method is used to detect low mol.wt. cpds., esp. environmentally important cpds. such as plant protection agents in drinking water.  The extra washing step eliminates both cooperative and competitive effects in the test, so that reagent requirements are relaxed, esp. unpurified polyclonal antibodies can be used and the degree of antigen substitution on the enzyme is less  critical.  The detection sensitivity is icnreased, e.g. a limit of 1ng/l in an enzyme-immunoassay system using a single photo-optical measurement. The test kits are simpler and less  expensive to produce.

Patent DE-4003623-A1 (DE)
Inventor: OPPEL WERNER DR
IPC: H01J37/32
Filed: 1990-02-07
Abstract: The invention relates to a process for controlling an installation for plasma treatment of workpieces. The installation has a constant voltage source for producing a glow discharge voltage V, which includes a control unit for controlling the magnitude of the glow discharge voltage V and a switch unit which can periodically switch off the glow discharge voltage V in various pulse-pause ratios. The installation also has a sensor for measuring the temperature of the workpiece, which is connected to the control unit so that the glow discharge voltage V is increased if the measured temperature is less than a given treatment temperature and decreased if the measured temperature is greater than the treatment temperature. The glow discharge voltage V is monitored so that if it falls below a lower threshold value the pulse-pause ratio of the glow discharge voltage V is reduced and if it exceeds an upper threshold value the pulse-pause ratio is increased.

Title: Device for forming homogeneous mixt. from exhaust gas - from Diesel engine and combustion chamber, comprising mixing tube with filter, disc and turning brake
Inventor: BERENDES HEINRICH
IPC: F02B3/06
Filed: 1990-05-10
Abstract: Particle filters through which diesel exhaust gases pass, may not be capable of complete regeneration due to uneven mixing of gases.
