Title: Vacuum decarburisation of chromium steel melts - avoiding chromium losses by monitoring oxygen content of waste gas
Inventor: PATEISKY GERHARD DR
IPC: C21C7/068
Filed: 1974-08-08
Abstract: The process for vacuum decarburising metal metls, particularly chromium steels in which an oxygen top or bottom blow is employed, or solid oxidation agents are added, comprises measuring continuously the oxygen partial pressure in the waste gas and interrupting the oxygen supply when a sudden increase in oxygen partial pressure occurs at the end of the main decarburization period. Pref. the reaction is controlled so that the sudden rise in the oxygen partial pressure occurs at a defined carbon content of the melt. Process reduces the oxidation of Cr considerably and consequently Cr losses without necessitating a time consuming analysis.

Title: Material discharge roller with eccentric rods - has rod carrier eccentric inside rotary tube to vary protruding lengths
Inventor: HEITMANN GUENTHER PROF DIPL IN
IPC: B65G65/48
Filed: 1974-09-02
Abstract: The roller is for the discharge, metering and layer formation of bulk material into mats etc., being particularly for material which does not flow easily. Inside a rotary tube (7) a rod carrier (3) is eccentrically mounted and rotates with it, so that the lengths of the rods (6) protruding through the tube walls vary during rotation. Thus for part of a revolution they transport the material, and for the rest retract into the tube to leave its surface free and smooth. A scraper (14) acting against the smooth portion removes any material still adhering to it. The degree of eccentricity of the carrier can be adjustable, and the rods can be in the form of bars whose flexibility is determined by special joints.

Title: Differential gearing for motor vehicles - has friction clutches to oppose the occurrence of undue torque differentials
Inventor: KAGATA TOORU
IPC: F16H48/22
Filed: 1974-10-05
Abstract: The gearing has a planet carrier supporting input bevels meshing with a pair of opposite output bevels each connected by a normally spring-engaged friction clutch to the carrier. The clutches are disengaged by small axial movement of output bevels under the drive thrust and the gearing is freed for normal differential action. The clutches are so connected to each other that when the torque on one of the output bevels falls, as by slipping of a road wheel, and the consequent fall in thrust on the bevel causes the associated clutch to engage, the other clutch engages with a like pressure and the different action is correspondingly inhibited.
