Title: Centrifugal blower with vol. control - has axially adjustable inlet venturi which limits effective blade width and permits recirculation through remaining width
Inventor: KOHL HANS
IPC: F04D29/42
Filed: 1976-12-10
Abstract: The centrifugal blower volume control comprises a housing (11) with impeller (12) with blades (17) arranged around a central inlet chamber (15), an inlet venturi (20) through which gas enters from the inlet opening (16), and a pressure chamber (18) surrounding the impeller and the venturi (20) from which chamber the gas passes to the blower outlet. The venturi (20) is axially adjustable within the chamber (15) by an amount (24), such that the end (22) of the venturi limits the effective width (29) of the blades (17) for the gas flow (27) from the intake whilst at the same time creating a passage (26) at the front end of the impeller through which gas can circulate (28) from the pressure chamber to the remaining width (30) of the blades.

Title: Underground diesel vehicle emergency stopping device - has temp. detector for water cooled exhaust controlling valve actuating fuel pump lever
Inventor: PETER SIEGFRIED
IPC: F02D17/04
Filed: 1977-01-27
Abstract: The emergency stopping device is for a Diesel-driven underground vehicle in which water is sprayed into the exhaust to cool it. A temp. detector on the exhaust pipe moves the injection pump to "stop" if temp. is excessive. The detector controls a pressure valve connected to a pressure source, and by a pipe to a cylinder actuating a lever on the injection pump. Where the engine is water-cooled, there can be a further temp. detector with a valve also connected to the cylinder. The pressure can be supplied by a compressed-air system, or from the engine lubricating oil system.
