Patent DE-3916493-A1 (DE)
Title: Spindle drive with spindle nut - has roller ring units engaging in spindle thread
Inventor: GAERTNER ROBERT DR
IPC: F16H25/22
Filed: 1989-05-20
Abstract: The spindle drive has a threaded spindle (1) and several rolling ring units (10,11,12) eccentrically enclosing the spindle and forming a spindle nut.

Title: Surface hardening - uses tungsten and inert gas burner to treat defined zones without heat loss
Inventor: HABERLING EDMUND DR ING
IPC: C21D1/09
Filed: 1990-03-08
Abstract: To harden the surface of prods. of martensitic steel, a wolfram/inert gas burner is moved to and fro over the surface to be hardened, across the direction of material travel. Pref. the workpiece to be hardened is on a worktable, and the wolframe/inert gas burner is clamped to the tool head of a spark erosion machine. The burner is directed particularly at sections which will be subject to wear, such as the closing edges of a plastics injection moulding tool, to give zones of raised strength and hardness. ADVANTAGE - The technique gives a precise hardening, within close tolerances, without heat flow loss into neighbouring zones. In an example, the workpiece is of steel Nr. 1.2311. The gap between the electrode point and the workpiece is 6.5 mm, and the current is rated at 60 A. The wolfram/inert gas burner is moved at a speed of 900 mm/min along a 20 mm wide track, while the workpice is advanced at a rate of 2 mm/min.. The surface hardness of the material extends to a depth of 0.8 mm while the surrfa surface hardness of the adjacent zone is up to a depth of 0.2 mm at 600-650 HV 0.2 against a core hardness of 300 NV 0.2. The hardened zone extends to a depth of 0.4 mm while the whole zone affected by the hardening treatment extends to 0.7 mm. The surface smoothness of the workpiece is unaffected by the hardening.
