Title: Rotary hydraulic damper for suspension of tracked vehicles - has oil cooled in pockets surrounding damper with rotor vanes on sleeve
Inventor: ZENZ WILHELM
IPC: B60G21/055
Filed: 1976-01-22
Abstract: The rotary damper for the suspension system of a heavy tracked vehicle has a rotor (3) mounted on a hollow shaft (1) which is in turn fixed to the tension bar spring. The sleeve (3) is provided with two vanes (12). The stator (4) is provided with vanes forming three chambers.

Title: Exhaust gas cleaning device - has tangential inlet into cylindrical space so that gas spirals into central exits
Inventor: SCHMITZ HUGO
IPC: B04C1/00
Filed: 1976-06-19
Abstract: Exhaust gas cleaning device for boilers etc. is used e.g. for removing the solids content such as dust and pptd. material resulting from neutralisation of the acid content.
