Title: Engine drive using exhaust gases - consists of bladed rotor with belt pulley on rotor shaft for power transmission
IPC: F02B67/04
Filed: 1974-03-11
Abstract: The mechanism makes use of the gas pressure of the exhaust gases of combustion engines and hence reduces fuel consumption without a drop in output of the engine. The pressure of the exhaust gases of combustion engines is used as additional drive force for the engine. This pressure can also be used to operate other equipment. The device consists of a housing with a bladed rotor and has a short inlet and outlet pipe for feed and extraction of the exhaust gas. A belt pulley is fixed to the rotor shaft and is used for power transmission. The pressure of the exhaust gas is applied to the rotor blades and thus the extra power is generated.

Title: Vertical transport arrangement for letters - has letter receiving slotted drum located next to horizontal track
Inventor: MANNS WOLFGANG
IPC: B65H5/00
Filed: 1975-03-04
Abstract: A vertical transport arrangement for stacked flat articles especially letters.
