Title: Disintegration of chromites
IPC: C01G37/14
Filed: 1977-02-18
Abstract: In the disintegration of a chromite or chromium-containing residue, wherein the chromium-containing material is disintegrated with an alkaline compound in the presence of oxygen and a diluent at a temperature above about 800 DEG C. and thereafter leached, the improvement which comprises pre-roasting the chromium-containing material prior to addition of the alkaline compound. Pre-roasting can be effected at 400 DEG to 1200 DEG C. with addition of certain amounts of silica dioxide and/or aluminum oxide and such additives, depending on the chromium containing material, if still required, are added-prior to disintegration and leaching-in such a quantity to establish a ratio of SiO2: AL2O3 of about 2:1 and further a ratio, calculated on the basis of NaOH as the alkaline compound, of SiO2: Na2O of about 1:0.5 plus a Cr2O3: Na2O ratio of about 1:2 to 1:4. Residues from previous leaching cycles can be present during disintegration as solid diluents but their contents of SiO2 and/or Al2O3 are not taken into account in calculating the SiO2:AL2O3 ratios. The process gives excellent results even with starting materials relatively high in SiO2 which are difficult to disintegrate to materials of desirable properties by other methods.

Patent ES-469995-A1 (ES)
Title: Forming curved segments from metal plates
IPC: C21D9/46
Filed: 1978-05-18
Abstract: A large flat metal plate is formed to have a three-dimensional shape of compound curvature by locally heating to an elevated temperature along predetermined lines and then quickly cooling, as by using a torch which carries a water spray nozzle. The heating extends completely through the thickness of the plate, and cooling causes significant shrinkage in the plane thereof in a direction perpendicular to the line of heating. Heating is carried out along lines in a geometric pattern and in a preselected sequence involving all quadrants of the plate so that it experiences a gradual transformation overall. The plate is normally supported upon an underlying cradle shaped to the desired compound curvature.

Patent ES-8102353-A1 (ES)
Title: Flowable medium detector with heater - has two temp.-dependent semiconductor devices of different thermal ranges, from whose differences medium presence is determined
IPC: G01F23/24
Filed: 1979-12-20
Abstract: The first temp.-dependent semiconductor device for the detector is supplied with current sufficient to heat the detector above ambient temp. The device is dipped into the measured medium, which provides a greater temp. gradient. A second semiconductor device for dipping into the measured medium is supplied with a lower current than the first one. Thus its heating effect is lower. The flowable medium is detected by differences between the two semiconductor devices. Pref. the two semiconductor devices are mounted at the same height, relative to the surface of the measured medium so that they are dipped into it, or retracted from it simultaneously. The temp. differences may be used for cutting off the voltage at both semiconductor devices so that the voltage difference may be also used for the detecting process. Typically Zener diodes are used and their anodes are interconnected. The detector finds application in liquid level measurement, or in aircraft height determination.

Patent ES-8107125-A1 (ES)
Title: A process for the preparation of silicon or ferrosilicon.
IPC: C01B33/025
Filed: 1980-10-23
Abstract: A process for the production of silicon or ferrosilicon by reduction of silicon oxide, optionally in the presence of iron or iron oxide, using a carbonaceous reducing agent, in a reduction furnace. The yield is improved without harmful temperature rises if the ratio of the amount of thermal energy supplied to the furnace to the amount of silicon oxide supplied to the furnace is made adjustable in such a manner that a value for the ratio can be set within an interval, which interval in its lower end is limited by the lowest value permitting constant reduction of the silicon monoxide and silicon directly with a certain part of the reducing agent which is supplied at the top of the furnace, because the amount of produced silicon monoxide is insufficient for complete conversion of all the carbonaceous reducing agent to silicon carbide at the top of the furnace, and in its upper end is limited by the highest value permitting constant reduction of the silicon oxide raw material to silicon monoxide and silicon directly with silicon carbide, because the amount of produced silicon monoxide is sufficient for conversion of the carbonaceous reducing agent to silicon carbide at the top of the furnace, and that a sufficient content of reducing agent is maintained in the lower, hotter, parts of the furnace so that reduction to some extent can take place directly with the reducing agent.

Title: Detachable balloon catheter apparatus and method.
IPC: A61B17/12
Filed: 1981-05-07
Abstract: A detachable balloon catheter apparatus and method. The apparatus includes an introducer catheter which is attached at its trailing end to a source of pressurized fluid. The leading end of the catheter is attached to an inflatable balloon which may be inflated as the pressurized fluid is injected through the introducer catheter. A valve mechanism is positioned inside the assembled introducer catheter and balloon and the leading end of the valve mechanism is bonded to the interior of the balloon. As the balloon is inflated by the pressurized fluid, a forwardly directed lateral force is exerted on the valve mechanism so that it is pulled forward into fluid-tight engagement with the valve seat placed at the opening of the balloon. Once the valve mechanism is pulled into fluid-tight engagement so as to close off the opening of the balloon, further injection of the pressurized fluid serves to detach the inflated balloon from the introducer catheter.
