Patent ES-443674-A1 (ES)
Title: Data processing system
IPC: G06F9/48
Filed: 1975-12-19
Abstract: In the data processing system containing a computer urgent tasks are processed in real time, that is to say at the instant at which they occur. However, this process may be found to be inadequate for protecting the computer against work overload during high traffic demand. The degree of occupancy of the computer is therefore determined by measuring the idle unoccupied time between repeated executions of a particular basic program of the lowest class of priority. The idle unoccupied time between time intervals of 10ms is measured in units of 25 mu s and compared with an upper and a lower limit value. Depending on the result of the comparison, the work load is reduced, left unchanged or increased. The system is used, in particular, for telecommunication switching purposes.
Patent ES-445349-A1 (ES)
Title: Production of aluminium
IPC: C25C3/06
Filed: 1976-02-20
Abstract: In the production of alumina for supply to electrolytic reduction cells in the production of aluminum metal, alumina trihydrate is calcined in a calcination furnace to convert it to alumina, typically having a water content of less than 2%. In the course of this operation fine particles in a size range below 44 microns are separated from the exhaust gases from the calciner. In conventional procedures these particles which are only partially dehydrated, are either recycled to the calciner or directly added to the calciner product alumina. With the dual objective of reducing environmental pollution and saving valuable alumina the present invention converts these collected fines into compacted granules in a size range of 150-5000 microns for supply to an electrolytic reduction cell either directly or after readmixture with the calciner product alumina.

The suspension was adjusted to pH 1.5 with H2SO4 and allowed to react with the flotation reagents for 10 mins. The suspension was then aerated. After 45 mins. impurities were removed. Yield of CaSO4 was 95.5%.
Patent ES-462184-A1 (ES)
Title: Apparatus for crystallizing an amorphous particulate material
IPC: F26B17/14
Filed: 1977-09-07
Abstract: Apparatus for crystallizing an amorphous material which is in granular form involves admitting the granular synthetic resin into a vertical crystallization zone and permitting the granular resin to descend through this zone under the influence of gravity. A counterflow of hot gas is passed through the descending granular resin and heats the latter to a temperature at which it transforms from an amorphous to a crystalline state. Once the granular resin has passed through the crystallization zone, it is subjected to abrasion for the purpose of separating crystalline particles which adhere to one another. An apparatus for carrying out the method includes a vertical vessel which extends outwardly and downwardly and which may be of rectangular or circular cross-section. An inlet for granular material and an outlet for spent gas are provided at the top of the vessel. An outlet for the crystallized material and an inlet for hot gas are provided at the bottom of the vessel. Baffles may be provided for distributing the hot gas evenly over the cross-section of the vessel. The vessel has a crystallization zone. Between this zone and the bottom of the vessel there is arranged a device for subjecting the crystallized material to abrasion. This device may be in the form of a plate mounted for reciprocating movement and provided with apertures of a size equal to the maximum particle size of the crystallized material. A shaft dryer may be arranged below the crystallization vessel to adjust the moisture content of the crystallized material to a desired value. The apparatus makes it possible to continuously crystallize granular synthetic resin at a high throughput and in an economical manner.
