Title: DC motor with moving yoke and brushes - has stationary armature commutator and field and interpoles may not be required
Inventor: WEH HERBERT PROF DR ING
IPC: H02K41/02
Filed: 1979-10-17
Abstract: The armature winding is contained in slots inside a laminated core (2). The winding ends are attached to commutator segments (3), typically mounted along one edge of the core. The field coils, or more typically permanent magnets, are arranged in the armature core underneath the slots to give a transverse magnetisation of the core. The flux path is closed by metal plates (1) which act as the yoke. These are attached to the moving path of the motor which also carries the brushes (5) and the armature current connections. The placing of the field excitation source gives a reduction in armature reaction to a point where it is almost negligible. Interpoles may thus not be reouired. If found necessary they are part of the moving assembly in the form of narrow plates between the main plates (1).

Title: Conveying table
Inventor: MUENCH WALTER
IPC: B65H18/22
Filed: 1981-01-15
Abstract: In the conveying and winding of very thin veneer webs, the inadequate inherent stiffness causes problems. The belt assumes a more or less undulating shape which causes damage to the veneer during reel formation. In the event of belt breakage, the web is knocked back by the air resistance, so that the automatic winding is impaired. To eliminate these disadvantages, the invention proposes a conveying table which is cambered in the region of the belt centre. As a consequence thereof, the belt assumes a slightly curved shape which has a stiffening effect. <IMAGE>
