Title: Low carbon steel sheet prodn. - by powder metallurgy using atomised steel powder of high carbon content
Inventor: BERNHARDT DIETER DIPL ING
IPC: C22C33/02
Filed: 1977-02-11
Abstract: Plain C steel of deep drawing quality contg. 0.1% C and of high purity oxides, is produced in sheet, strip or tube form by powder metallurgy in which a non-alloyed steel powder having a high C content 0.2-1.0 wt.% is compacted in known manner to porous strip or bar having a pore volume of >=5% by rolling or pressing. The semi-prod. is annealed for a brief period in a protective gas atmos. at 500-1300 degrees C and then spaced to give the final prod. of high density. Method eliminates the formation of solid deoxidation and spinel -type oxide skins.

Title: Stereo photogrammetric map processor - relieves linkages of thrust forces by springs and supports using cardan joints
Inventor: BREU ROLF
IPC: G01C11/04
Filed: 1977-05-24
Abstract: A stereo photogrammetric processor has linkages to convert air photographs into maps.

Title: Duplicated control system for telephone exchange - has reverse control maintained in operation using own data store in parallel with active system for high reliability
Inventor: BUNKENBURG MICHAEL ING GRAD
IPC: G06F11/20
Filed: 1977-06-22
Abstract: A data processing and control system is used for the control of peripherals.

Title: Admixing small fluid quantities - by intermittent feed from closed circuit zone
Inventor: LEHMANN KURT DIPL PHYS
IPC: B01J19/00
