Title: Exhaust gas detoxification unit - has afterburner sepd from catalyst section by air venturi and nozzle tube
Inventor: LANG LUDWIG DIPL ING
IPC: F01N13/02
Filed: 1971-09-15
Abstract: In the parent patents, a detoxification device for the exhaust gases of internal combustion engines introduced ambient air in a chamber in the pipe to an oxidn. catalyst. An exhaust gas/fresh air mixer is followed by the catalyst, each fitted with a flow accelerating device. In the addn. the central tapered channel of the catalyst container surrounds an exhaust gas injector tube which terminates with its orifice in an annular nozzle of a nozzle chamber. The latter is joined by ports to an air chamber, formed between a venturi tube and the outer perforated casing. The dynamic air pressure of a car in motion acts on these perforations. This improves the flow passing through the catalyst; the internal resistance is now no higher than that of a conventional silencer.

Title: Ultrasonic welding of plastics - by applying mechanical oscillations from transducers to both sides of the work piece
Inventor: LEVEN DIETRICH DIPL PHYS
IPC: B29C65/08
Filed: 1972-10-20
Abstract: Two electrical generators produce high frequency currents and are linked together in frequency, amplitude and phase.
