Patent DE-2453280-A1 (DE)
Title: Engine exhaust gas treatment - by passing through conical thin walled insert of catalytic material in exhaust pipe
Inventor: BARNERT KONRAD ING GRAD
IPC: F01N3/28
Filed: 1974-11-09
Abstract: The concn. of toxic constituents in the exhaust gases of i.c. engines is reduced by mounting, in the exhaust gas pipe close to the exhaust valves, a slightly convergent thin-walled tube section, which is clamped with a flange between the exhaust gas manifold and the exhaust pipe. The tube consists of a rapidly heated, heat resistant material which has catalytic properties or it is coated with such a material on the inside surfaces. This is a simple way of improving the after combustion of exhaust gases and of reducing the emission of noxious gases. The thin walls heat up rapidly and become active soon after the start of an engine. The device can be easily added to older types of engines.

Title: Horizontal runner channels for filling foundry moulds - with increasing runner section to compensate for frictional losses
Inventor: NIELSEN FRIEDRICH
IPC: B22C9/08
Filed: 1974-12-06
Abstract: Casting systems have horizontal distribution channels or runners, which possess >=1 slightly conical sections which increase in the direction of travel of the melt and, after each runner-branch, there is a stepped redn. in the cross section of the main runner which then increases continuously (i.e. up to the next runner-branch). The coninicity of each section of the main runner between the runner-branches is pref. proportional to the frictional losses in the energy of the melt flowing along the runner, the geometric configuration of the runner profile compensating for the frictional losses. Improved filling of foundry moulds and therefore better quality castings are obtd.
