Title: Variable drive document shredder - has multipole electric motor with reaction controlled selection of pole pattern for torque regulation
IPC: B02C18/24
Filed: 1992-03-07
Abstract: The shredder elements (37) are driven by the multipole electric motor (31) via a flexible drive (30) which is deformed by the reaction force on the shredder elements.

Title: A process for producing machine components, in particular rolling bearing elements
Inventor: GRELL KARL-LUDWIG DIPL ING
IPC: C21D6/02
Filed: 1993-02-10
Abstract: The invention relates to a process for producing machine components, in particular rolling bearing elements, whose mechanically stressed surfaces consist of a steel of increased carbon content and whose load-bearing parts consist of a low-alloy steel of low carbon content. The process is characterized in that a core material (1.1) of low carbon content is roll-clad on at least one side with a coating material (1.2) of increased carbon content, this composite material is hardened and heat-treated, so that the coating material (1.2) has a hardness of 300 to 550 HV and the core material (1.1) has a hardness of 250 HV, and the composite material is subsequently formed by single-stage or multi-stage cold-forming. The result is that, on the one hand, due to the cladding of the strip and the subsequent tempering, a synergistic effect is produced, that is to say the materials mutually influence each other and thus allow good formability of the strip, while, on the other hand, due to the forming step or forming steps in the individual calibration stages, a cold-worked, smoothed running track or surface is formed which has an adequate load-bearing capacity for rolling bodies. <IMAGE>

Title: Method and arrangement for the controlled starting of the flow of steel through the outlet of a steel ladle
Inventor: TOMA-DISLICH MARGIT DR
IPC: B22D41/46
Filed: 1993-06-26
Abstract: A description is given of a method for the controlled starting of the flow of liquid steel through the outlet of a steel ladle. The method is employed when the layer of sintered slide-valve filling composition withstands the ferrostatic pressure of the liquid steel, i.e. there is no self-opening. To break this layer of sintered slide-valve filling composition, a force application medium is introduced through a hole in the slide valve plate into the space bounded by the boundary layer and the slide valve plate. As a force application medium use is made, for example, of a gas or a solid body. The breaking through of the sintered layer is monitored and the slide valve plate is moved without delay into a position in which the outlet is open when the breakthrough is made. An arrangement for carrying out the method is also described.
