Patent DE-2442446-A1 (DE)
Title: Sewage pump for water containing solids - has impeller with blades attached to outer shroud and open centre
Inventor: KRAEMER HANNES
IPC: F04D29/18
Filed: 1974-09-05
Abstract: The pump is arranged vertically with a motor (5) driving a shaft (4) which carries the impeller (1). The impeller has a hub (3) which is attached to the shaft and an outer casing (10) acting as a shroud ring which takes the form of a circular cylinder tapering inwards from the upper outlet end to the bottom suction end (7). Inside the casing are two centrifugal blades (2) twisted spirally with discharge edges (6) opening to the pump casing (12) discharge volute and inlet edges facing the pump suction (7). They are held on the impeller casing or shroud ring (10) and arranged so that there is a cylindrical core left empty in the centre of the impeller.

Title: Measurement of turning moment - using torque tube on agitator shaft with outer reinforcing sheath
Inventor: BRUSS HERBERT K
IPC: B01F15/00
Filed: 1974-09-16
Abstract: The measurement of turning moment is carried out industrially by use of a torque tube attached to a rotating shaft. Lateral flexing of the shaft is avoided by using a reinforcing sheath around the torsion element in the form of a tube, one end of which is rigidly fixed to the element mounting and the other end mounted in a frictionless bearing. The sheath can be mounted to strengthening struts on the torsion element. A sliding bearing can be used at the other end, lubrication being provided by the contents of the vessel into which the shaft projects. It can have such a gap that contact only occurs when deflection of the shaft occurs.

Title: Permanent magnet drive system - has equally spaced magnets on armature and has axially moving field magnets in housing
Inventor: LOBITZ GUENTER
IPC: H02K53/00
Filed: 1975-12-12
Abstract: A number of permanent magnets is mounted, equally spaced, on an armature. They are axially magnetised at equal spacings with opposite polarities. Field magnets are installed on the inner surface of a round housing, and can be axially moved. The air-gap between armature magnets and field magnets is as small as possible.
