Patent ES-421959-A1 (ES)
Title: Treatment of vulcanized rubber
IPC: B29B17/04
Filed: 1974-01-02
Abstract: The invention provides finely divided vulcanized rubber having a particle size of generally less than 20 microns for re-use in the rubber industry. Vulcanizates produced from compositions containing the finely divided vulcanized rubber, either as the sole rubber component or in admixture with unvulcanized rubber, have properties significantly better than those of vulcanizates of similar compositions containing conventional reclaimed rubbers. Vulcanized rubber is converted into the finely divided rubber by the steps of (1) contacting vulcanized rubber with a fatty acid, (2) contacting the product of step (1) with a solid alkali and (3) forming a dispersion of the product of step (2) with a liquid which dissolves the alkali but does not affect the rubber. Alternatively, the finely divided vulcanized rubber results from the steps of (1) contacting the vulcanized rubber with a liquid effective to swell the rubber and thereby weaken it e.g. tetrahydrofuran, (2) comminuting the weakened material and (3) removing the liquid from the comminuted material.

Patent ES-429314-A1 (ES)
Title: Electrolytic manufacture of chlorine and sodium carbonate
IPC: C01D7/07
Filed: 1974-08-16
Abstract: Manufacture of chlorine and sodium carbonate using a combination of electrolysis of an aqueous solution of sodium chloride in a diaphragm cell, carbonation of the caustic brine leaving the cell, and the ammonia-soda method of making sodium carbonate. An aqueous solution of sodium chloride is electrolyzed in at least one diaphragm cell to form a caustic brine. The caustic brine leaving the cell is carbonated and further treated. This is first done in a soda plant without ammonia by treating the caustic brine in at least one monocarbonation scrubber by reacting the caustic brine with a gas having a low carbon dioxide content without causing bicarbonate precipitation in the monocarbonation scrubber to form a monocarbonated caustic brine, and treating the monocarbonated caustic brine in at least one bicarbonation column by reacting at least part of it with gas rich in carbon dioxide to precipitate sodium bicarbonate in the bicarbonation column and to form a mother liquor. The precipitated sodium bicarbonate from the mother liquor is separated by filtration. The separated mother liquor is de-bicarbonated by converting the dissolved bicarbonate to carbonate. The de-bicarbonated mother liquor is saturated with respect to sodium chloride. Then the saturated liquor is treated in an ammonia-soda process for making sodium carbonate and the saturated liquor is used as at least a partial source of sodium chloride for such process.

Patent ES-466878-A1 (ES)
Title: Waste incinerator exhaust gas treatment and apparatus
IPC: B01D53/68
Filed: 1978-02-10
Abstract: The disclosed treatment is for the removal of hydrogen halide constituents of an exhaust gas by means of a dry scrubbing agent to which the gas binds. The agent is sprayed into the gas in finely divided form just prior to flow of the gas through a register located at the entrance to a filter chamber. The agent is thus distributed evenly over the input of the filter and performs its binding function primarily while on the filter. The agent may be sprayed as a finely divided solid or as a fluid which rapidly dries to leave a coating of finely divided agent on the filter. Also disclosed is an apparatus for practicing the method, including a nozzle casing with a plurality of spray nozzles located in the gas passageway at the input side of a register at the entrance to the filter chamber housing an electrical filter. The filter elements of the filter are so designed that the gas passageways between them force the gas to make periodic, sudden changes in direction which lead to a pulsation and a resulting gas turbulence. The turbulence improves the action of the agent on the gases.

Patent ES-472296-A1 (ES)
Title: Process for the preparation of a vegetalbe protein extract
IPC: A23J1/14
Filed: 1978-08-02
Abstract: Vegetable proteins and phytic acid, or even antitrypsin factor in the case of soya bean, are separated at a pH slightly higher than the isoelectric pH of the said vegetable proteins, namely at a pH value within the range defined as ISO + 0.5 </= pH </= ISO + 1.2 with respect to the isoelectric pH designated by the abbreviation "ISO". This pH value is chosen because phytic acid and, where appropriate, the antitrypsin factor are relatively quite soluble at this value whereas most of the proteins are not and will not go into solution at this value. The separation is carried out during the manufacture of vegetable protein isolates or by washing flours, concentrates or isolates of vegetable proteins. Vegetable protein extracts low in phytic acid, or even in trypsin inhibitor in the case of soya bean, are obtained by this process.

Patent ES-475018-A1 (ES)
Title: Mosaic printer
IPC: B41J2/00
Filed: 1978-11-13
Abstract: A mosaic printer is made secure from unauthorized interception of data by falsifying the needle drive pulse current magnitude and sequence so that electromagnetic leakage radiation cannot be used to determine the alphanumeric data being printed. This falsification is accomplished by a compensation device having compensators energized each print cycle in addition to the printer needle drives in a reciprocal or a pseudorandom manner. The compensators have current consumption characteristics nominally identical to the needle drives and produce substantially identical radiation pulses, making it impossible to correlate the radiated pulse format with the symbol being printed.

Patent ES-8101797-A1 (ES)
Title: Traffic signalling system.
IPC: G08G1/07
Filed: 1980-05-29
Abstract: A method and a circuit arrangement for modifying central control information commands forming signal programs in traffic signal systems in particular street traffic signal systems, the central control information commands being output from a central station to intersection devices of the system in order to control signal generators assigned to the intersection devices. This modification is to occur through the use of traffic information which are determined in the traffic areas whose traffic flows are to be controlled by the signal generators of the intersection devices. In order to be able to undertake a modification of the signal program sequencing in the respective intersection devices, modification time areas are determined in the form of partially overlapping central control information commands, in particular binary "1's" transmitted from the central station to the respective intersection device. Within these modification time areas, separate local control information commands can become effective for setting the signal generators.
