Patent ES-8202206-A1 (ES)
Title: Turbine set with a generator providing a constant-frequency mains supply.
IPC: H02K7/18
Filed: 1981-02-10
Abstract: In a turbine set with an axial flow which is traversed by water and which is coupled to a generator feeding a network of constant frequency, the flow turbine is a propeller turbine with non-adjustable blades. The stator winding of the generator is connected to the network by means of a frequency-controllable converter, in particular a direct converter. The speed of rotation of the turbine set is controllable continuously according to the power to be delivered. In the case of an asynchronous design of the generator, it is advisable to provide the stator with a waterproof jacket on the inside and to flange it into the turbine tube, since the rotor with its cage winding is swept by water.

Patent ES-8303688-A1 (ES)
Title: Conveyor calibration technique.
IPC: G01G23/01
Filed: 1981-10-20
Abstract: A method for calibrating a bulk material weighing and metering conveyor (12) of the endless belt type wherein a belt speed signal (44a) and a tare-adjusted weight signal (43) are multiplied to provide a product signal (45) that is converted into a periodic pulse signal (48) whose frequency indicates the feed rate (net weight per unit of time) of the material being metered by the conveyor (12). In a first calibration step, the weight of the empty conveyor belt is measured over one belt revolution by counting the periods of the feed rate indicative pulse signal. This count is then used to establish a tare weight reference value. With the tare weight reference value established and the feed rate signal compensated therefor, a second calibration step is performed wherein the periods of the feed rate indicative pulse signal are again counted for a known increment (d) of belt travel with a known net weight of material for such increment of belt. This second count is compared to the theoretically expected count, such comparison being used to determine the accuracy of the indicated feed rate and to effect necessary calibration adjustments if needed.

Title: Recovery of chlorine.
IPC: C22B1/08
Filed: 1985-06-12
Abstract: Chlorine may be recovered from residues from the fluidized bed chlorination of iron-containing metalliferous oxidic materials, such as ilmenite, bauxite, chromite, wolframite, scheelite, tantalite or columbite, the residues containing condensed iron chloride and blow-over bed solids, by heating the residue to revolatalize the iron chloride and reacting it with oxygen. The quantity of iron chloride in the oxidic material is controlled relative to the quantity of blow-over carbon so that the quantity of carbon is sufficient on combustion to provide the required heat but is insufficient to cause undue dilution of the chlorine produced by virtue of its combustion products. Chlorine of a concentration suitable for direct recycle to a chlorination process, e.g. of 30% to 50% volume concentration is produced.
