Title: Ion exchange conversion of calcium sulphate
IPC: C01D5/10
Filed: 1983-09-02
Abstract: Conversion is effected by treating an aq. paste of calcium sulphate at low pH to an anion exchange resin carrying chloride ions. The sodium or potassium sulphate is recovered from the exchanger effluent and the anion exchanger is regenerated with sodium or potassium chloride. - The process enables phosphogypsum a by-product from wet process phosphoric acid prodn., to be converted to the more useful, and more easily handled soluble sulphates. Environmental problems caused by the heavy metal content of the phosphogypsum are overcome since such metals are more easily extracted from the soluble sulphates. - Suitable anion exchange resins include Dowex WGR, Duolite A374, and Amberlite IRA 60 (RTM). The calcium sulphate is adjusted to a low pH with sulphuric or hydrochloric acid and the prod. sulphate may be pptd. from soln. by addn. of sodium or potassium chloride. The soln. remaining may then be used to change the resin with chloride ions. (0/0) DEAB- DE3331416 C K2SO4 and Na2SO4 is produced by (A) reacting a CaSO4 slurry 03under acid conditons with an anionic exchanger contg. Cl-and (B) passing a soln. of NaCl or KCl through the exchanger and recovering Na2SO4 or K2SO4 from the exchanger effluent. The pH in the CaSO4 slurry is pref. adjusted to 0-4 with H2SO4 or hydrochloric acid. Sea water is pref. used in part to obtain the CaSO4 slurry.
Patent ES-8501577-A1 (ES)
Title: Control Means for a Power Converter
IPC: H02M7/48
Filed: 1984-04-02
Abstract: Control means for a power-converter WR enables automatic testing of the operational readiness of the converter for parallel operation with other converters (not shown) at a common load rail S. A control unit 1 controls and monitors operation of the converter, a control unit 2 regulates the output power via unit 1, and a control unit 3 tests the readiness for parallel operation. Following preliminary testing of the control, monitoring and power regulating functions of units 1, 2, signals on lines 101, 102 cause unit 3 to effect the parallel operation readiness test. Unit 3 causes units 1 and 2 to first control converter WR to give a higher than nominal output and this is checked by a voltage monitor SpW resulting in an acknowledge signal on line 106. Units 1 and 2 are then caused to operate converter WR at a lower than nominal voltage, resulting in an acknowledge signal on line 107. If both signals 106, 107 are obtained, a contact K3 is closed to connect converter WR to line S. Absence of either or both of signals 106, 107 indicates unreadiness for connection and the converter is de-energised via AND gate 3/5 and line 108 when a timer 3/1 of unit 3 times out.
Patent ES-8502212-A1 (ES)
Title: Diesel internal combustion engine
IPC: F02N19/00
Filed: 1984-04-12
Abstract: In a turbocharged diesel internal combustion engine (10) with low compression ratio, at least one cylinder (11) operating as an engine cylinder is charged during starting and at partial load operation by several cylinders (18, 21, 28) operating as compressors. The pistons of the compressor cylinders (18, 21, 28) lead the piston of the engine cylinder (11). As a result thereof, the engine cylinder can be charged during its compression stroke. The compressor cylinder (28) which by reason of its large angular ignition spacing to the engine cylinder cannot feed directly into the engine cylinder, delivers its supplied air at first to another compressor cylinder (18) which is located more favorably. Only thereafter, the air of the two compressor cylinders (18 and 28) is fed in common and in parallel with a further, possibly also favorably located compressor cylinder (21), to the engine cylinder (11).

Patent ES-8708273-A1 (ES)
Title: Cable television system selectively distributing pre-recorded video and audio messages
IPC: H04N7/173
Filed: 1986-04-28
Abstract: A method of, and a system for, selectively delivering still television video with accompanying audio to home subscribers over a cable television system for advertising, promotional or educational purposes. A maximum number of home subscribers can interactively request presentations of their own choosing to be displayed on their home television sets. Only one standard television channel is required for transmission of still video with accompanying audio to serve 300 concurrent users. No equipment is required in the subscriber's home. The video is presented as still frames from one of a number of videodisc players, transmitted over one television channel during the appropriate time interval of 1/30th (or 1/25th) of a second. Such video frames, which may also contain overlaid graphics information, are uniquely addressed to a remote storage device. Unused bandwidth is used for the transmission of up to 300 discrete audio messages. The remote storage device identifies the appropriate video still frame, stores it, combines it with the corresponding audio message and conveys both to the home subscribers' television on a pre-selected channel. By uniquely addressing video frames to the remote storage device, either 30 (or 25) different video frames per second can be conveyed on one television channel to 30 (or 25) different remote storage devices for retransmission to home subscribers. Thus, if a home subscriber sees a given still video frame for 10 seconds, his remote storage device need not be updated for those 10 seconds, enabling the system to transmit 300 (10 secondsx30/second) different video frames to 300 other remote storage devices, thereby serving 300 concurrent users.
Patent ES-8705662-A1 (ES)
Title: Management system for parking fees.
IPC: G07B15/02
Filed: 1986-06-06
Abstract: A system for controlled meter parking of road vehicles comprising a parking meter and a portable terminal for use by a checker of the controlled meter parking. A keyboard allows drivers to enter vehicle data. A parking time limit is calculated as the function of the amount of money paid. The parking meter then stores pairs of data items, where each pair contains a vehicle data item and an associated parking time limit. In one embodiment, the amount of money is read from a memory card to allow the driver to receive credit for any time not used upon return to pick up the car. The system includes a clock for comparison with the parking time limits. When the comparison with the clock indicates that a parking time limit has expired, the associated pair of data items are deleted from the parking meter memory. A portable terminal allows a checker to enter identification data corresponding to a vehicle actually parked in one of the parking spaces. If there is no identification data in the parking meter memory corresponding to the data entered by the checker, a warning signal goes off on the portable terminal to alert the checker that the vehicle is in violation. Further, if the checker determines that the parking time limit in the portable terminal memory has expired by comparing that limit with a clock in the portable terminal, the warning signal all goes off.

Title: Television apparatus Pix-in-Pix.
IPC: H04N5/262
Filed: 1987-03-18
Abstract: A pix-in-pix television display includes circuitry for reducing the amount of memory needed to hold one field of the reduced size image.
