Title: Walking beam for cooling bed for sheet - metal
Inventor: MUELLER ADOLF
IPC: B21B43/02
Filed: 1969-11-25
Abstract: Walking beam support for use in cooling beds used in continuous rolling mills, designed such that the moving beam describes such a vertical path that is raised and deposits the workpieces onto the stationary beam in a shock-free gentle manner so as not to damage it, this being achieved by imparting a very flat profile to the cam profile of the lifting block on which the beam travels. Such action not only benefits the workpiece but also the various linkages of the walking beam mechanism.

Patent DE-2336035-A1 (DE)
Title: Magnetic separation of minerals - under irradiation by high frequency in fluidised bed gives improved uniformity and selectivity
Inventor: SCHUELLER KARL HEINZ PROF DR
IPC: B03C1/015
Filed: 1973-07-14
Abstract: Separation of minerals by magnetic means has improved selectivity if the magnetic properties are altered by irradiation with high frequency electromagnetic radiation. This is efficiently carried out if the irradiate space also forms a fluxed bed for the material being treated. If the fluidising gas is carefully selected, chemical reactions can be carried out. The bed can be constructed as a transport conveyor which passes through an irradiated sector. Is of particular application to the treatment of clays contaminated with pyrites. The use of a fluidised bed ensures good mixing and homogeneity in the product being treated. This avoids local overheating and general non-uniformity in it. The radiation space can be tailored to the fluid bed.

Title: Hydrodynamic multipurpose drive system - used for transmission of driving power of engines to drive shaft of ships or vehicles has multiple rotor
Inventor: MARTENS PETER
IPC: F16H39/22
Filed: 1974-07-01
Abstract: The hydro-dynamic drive transmits the power from one or more engines simultaneously independent from the axial orientation of the engines, and can be used for speed reduction, speed increase or for reversing the direction of the drive. It can be used while using the same construction components as a pump and/or a compressor. The drive system can consist eg. of several motors and a turbine which each drive a pump.
