Title: Process for extraction of phosphorus compounds
IPC: C01B25/22
Filed: 1971-11-12
Abstract: An extraction process for recovery of phosphorus compounds from both low and high grade phosphate ores utilizes a room temperature extraction with dilute mineral acids whose calcium salts are water soluble. Preferably the ore is coarsely ground. Dissolved impurities are removed from the dilute phosphate solution by a first neutralization step, whereafter further neutralization precipitates high purity calcium hydrogen phosphate. The latter may be converted to high purity phosphoric acid by treatment with sulfuric acid. Either lime or ammonia may be used advantageously as a neutralizing agent.

Title: Method and apparatus for controlling the operation of a steel refining converter
IPC: C21C5/30
Filed: 1973-07-31
Abstract: A method and apparatus for controlling the operation of a steel refining converter of the type having bottom tuyeres, each tuyere consisting of a center jet surrounded by annulus jets is disclosed. Controls are provided for blowing oxygen through the center jets and a fuel gas, such as propane, through the annulus jets during the refining step. Gases, such as nitrogen and compressed air, are blown through the jets during other parts of the steel making process. By means of switching circuits, the flow of each selected set of gases is established before the previously selected set can be cut off, one set of gases is automatically substituted for another if there is a loss of pressure at the tuyeres, nitrogen is substituted for oxygen and fuel if the flow of either of the latter two gases falls below a predetermined value and tilting of the converter to an upright position is prevented unless there is adequate pressure in the tuyeres. The disclosed apparatus ensures that molten metal will not enter or damage the tuyeres thereby preventing severe damage to the equipment and possible hazards to operating personnel.

IPC: C02F1/465
Filed: 1977-01-18
Abstract: A continuous process and plant for agglomerating solids, partic. of colloidal dimension, from suspension in a liq. to facilitate sepn. and purificn. of the liq. is claimed. The liq. flows continuously between two electrodes operating on A.C. at 0.2 to 800 HZ and with a current density of 1.24 to 93.0 amps/dm2, while the liquid is agitated to a turbulence equivalent to a Reynolds number of about 10,000.

Treated water is clarified and deodorised by the hydroden peroxide. The electrodes are kept clean by scrubbing action of particles in the fluidised bed.
Patent ES-456356-A1 (ES)
Title: Coating grinding material having layer of spherical grinding body
IPC: B24D11/00
Filed: 1977-02-28
Abstract: A grinding or abrasive agent on an underlay comprises spherical grinding granules bonded to the underlay and each comprising a large number of abrasive grains. The spherical granules contain the abrasive grains embedded in an organic binding agent matrix, the hardness of which is not harder than the normal binding agent which is used for bonding the spherical granules to the underlay. Pref. the spherical granules contain 80-97% of abrasive grains and 3-20% of organic binding agent matrix. Up to 60% of the organic binding agent matrix may be replaced by fillers. The organic binding agent matrix pref. comprises a phenol formaldehyde resin, urea formaldehyde resin or malemin resin. The mean dia. of the spherical granules is pref. 300-2000 mu and is 3-500 times the mean dia. of the abrasive grains. A high, uniform grinding performance accompanied by a long-lasting roughness depth is obtd. without a tendency to become prematurely clogged. Due to the relative softness of the binding agent between the abrasive grains in the spherical granules, the abrasive grains are continuously and uniformly exposed to provide the grinding action, without a risk of the surface of the workpiece becoming scratched, since the granules themselves do not act as a large abrasive grain.

Title: Process for producing Ni-Fe magnetic tape cores
Inventor: PFEIFER FRIEDRICH
IPC: H01F41/02
Filed: 1979-04-05
Abstract: An alloy comprised of 45 to 53 wt. % Ni with the remainder iron, and including small amounts of deoxidizing and processing additives is worked into a 0.01 to 0.1 mm thick tape, wound to form a tape core and is then subjected to a final annealing for at least one hour at a temperature of at least 900 DEG C. and thereafter is subjected to a tempering in a magnetic cross-field (i.e., the magnetic lines of force are applied in the plane of the tape perpendicular to the rolling direction thereof). The process provides high impulse permeabilities at induction rises of 1T or larger within the so-processed tape cores. Particularly high impulse permeabilities are achieved in instances where an anisotropic structure with a privileged grain direction <001> in the rolling direction is generated in the tape material via heating and final deformation before winding into a tape core and via a final annealing after winding of the tape core. The so-produced tape cores are useful in various electrical applications, particularly in pulse transformers and thyristor choke coils.

Patent ES-487331-A1 (ES)
Title: Device for triggering a semiconductor switch
IPC: H02P25/26
Filed: 1979-12-28
Abstract: In a slope ignition generator for the triggering of semi-conductors, the slope is generated by the charging of a condensor (47), through an operational amplifier (39), by a stabilised voltage (U) having an amplitude proportional to the frequency of a synchronisation signal (U1) the excursions to zero of which are detected (at 42) to discharge the condensor. The slope voltage is compared (at 49) with a reference threshold voltage (Vr). As a result, the triggering angle of the semiconductors is independent of the frequency. The invention is applicable to the fine adjustment of the speed of an asynchronous polyphase motor having a wound rotor.
