Title: Grain-oriented silicon steel sheet prodn - avoiding oxide inclusions to allow lower manganese and sulphur contents
IPC: H01F1/147
Filed: 1975-05-22
Abstract: In the prodn. of grain-oriented silicon steel sheet by hot rolling a slab to strip, two-stage cold rolling the strip with an intermediate anneal, subjecting the strip to a decarburising primary recrystallisation anneal and then box annealing to produce secondary recrystallisation, the improvements are that the Mn and S in the steel are controlled so that the solubility product, %Mn x %S, is 0.007-0.0012, that the steel is cast so that oxidation of constituents in the surface of the casting stream, which lead to insoluble oxides distributed within the steel, is reduced to a minimum, that the steel slab is reheated to 1166-1310 degrees C before hot rolling and that the sheet is reduced by 44-56% by the second cold rolling step. By restricting the amt. of oxides dispersed in the steel, the effectiveness of MnS as grain growth inhibitor is increased. Thus the amt. of MnS in the steel and hence the reheating temp., can be reduced. The degree of reduction in the final cold rolling step gives optimum grain orientation.

Before or after hardening of the teeth, the grinding ridges which run in a horizontal direction at the root of the teeth are removed using a grindstone with very fine grit. The saw blade moves forward intermittently during the grinding process, and the grindstone is only applied when the saw blade is stationary. The grindstone is driven by a compressed air motor.
Patent FR-2325736-A1 (FR)
Title: Purifying chromium contg. solns. from rinsing baths from pickling - by electrodialysis continuously using specified apparatus
IPC: C25D21/16
Filed: 1975-09-23
Abstract: An apparatus for purifying toxic effluent contg. hexavalent Cr continuously by electrodialysis comprises a treatment tank, connected to the effluent tank via pumps and filters, which contains an accessible cathode compartment which is separated from the anode comparment by anion exchange membranes. The cathode surface is low in relation to the anode surface to maintain a strong cathode polarisation by a continuous current from a low voltage generator. The impurities pptd. in the cathode compartment are removed by cleaning. The anion exchange membranes result in enrichment of hexavalent Cr in the anode compartment solution which is recycled as necessary via a control valve for further use. The effluent arises from pickling baths used in electroplating processing. Compared with previous treatments, the above is cheaper, recovers the hexavalent chromium for further use and is continuous. The effluent which is fed from the washing bath after pickling is recycled and therefore the rinsing bath is maintained at a constant quality level.

Title: Coating of agricultural prod. with viscous liq. - using rotating brushes and continuously agitated applicator
IPC: B05C1/08
Filed: 1975-09-29
Abstract: Coating machine for treating agricultural prods. with a viscous liq., such as a mixt. of wax and a fungicide, comprises a chamber enclosing two shafts fitted with cylindrical bristle brushes; a set of six relatively small brushes rotates underneath around shafts. The prods. to be treated enter at the inlet chute and are guided between the brushes to the evacuation chute. The liq. is pumped into the cylindrical reservoir fitted with orifices and baffles; a horizontal shaft running in bearings lifts the liq. by the blade to the level of the orifices from which it drips, drop by drop, on the brush and is transferred to the prods. Excess liq. is returned to the pump via the overflow tube. Prods. can be treated at a relatively low speed in a comparatively simple machine; as the liq. is continuously agitated in the applicator, any risk of blocking the orifices is eliminated.
