Patent ES-462120-A1 (ES)
Title: Process and installation for drying and heating coal
IPC: C10B57/08
Filed: 1977-09-05
Abstract: Coal is passed in a two-stage process through a drying and heating zone. The coal coming from the drying zone is separated from the heat carrier gas which is then passed into the atmosphere after going through an electrodust separator. The dried coal is delivered into the heating zone. The hot gas for the heating zone is furnished by a combustion device. The exhaust gas from the heating zone is separated from the heated coal which is recovered while the exhaust gas is passed back into the drying zone. Part of the hot combustion gas coming from the combustion chamber is branched off and passed into the exhaust gas coming out of the drying zone either directly behind the drying zone or behind the separator for separating the dried coal from the exhaust gas. The temperature of the exhaust gas from the drying zone is thus prevented from sinking below the sulfuric acid dewpoint or water vapor dewpoint which might result in corrosive damage to the apparatus, particularly to the electrodust separator.

Patent ES-470175-A1 (ES)
Title: Control of i.c. engines
IPC: F02M25/07
Filed: 1978-05-24
Abstract: A method and apparatus for controlling the running of a spark-ignited I.C. engine (10) under conditions of fuel input less than stoichiometric, to improve the efficiency and stability of running under these conditions, utilises an ionisation detector (16) positioned in the engine exhaust gas duct (14) to detect those firing cycles with "late burn" of the combustible mixture during the firing stroke. The detector senses the increased ionisation of the exhaust gas flow caused by such "late burn" cycles, and produces unusually large voltage spikes (15) in its output signal corresponding to the occurrence of these "late burn" cycles. A control circuit (19) progressively weakens the combustible mixture in steps during running of the engine (10) until one or more such unusually large voltage spikes (25) occurs in the detector output, in response to which the control circuit (19) automatically produces a feedback signal which enriches the mixture to a higher value.

Title: Method and apparatus for controllably recycling the solids content of the effluent from an asbestos-cement products forming plant
IPC: B01D21/34
Filed: 1979-04-02
Abstract: Waste water effluent from online production machinery and/or clean-off water from shut-down machinery is deposited in a settling tank in which the solids settle out. Water, relatively clear of the solids, is returned to the production plant. A slurry containing a high concentration of these solids is, depending on the percentage of solids, either returned to the production machinery via a slurry tank or returned to the settling tank for further concentration. The degree of concentration of solids in the slurry tank is carefully controlled in order to permit the addition of these otherwise wasted solids to the virgin asbestos-cement slurry in the various production machineries. This addition of the otherwise wasted solids is carefully monitored at each of the production machinery installations in order to provide proper quality control of the product produced thereby. This system may further include an effluent level sensor in the settling tank in order to optimize the clarity of the clean water return as well as a pH control system which can be used to aid in precipitating out the various dissolved solids, and to chemically condition the various fluids in the effluent return system, resulting in improved quality control of the asbestos-cement end product.

Title: Technique to reduce the zeolite molecular sieve solubility in an aqueous system
IPC: B01J20/32
Filed: 1980-06-12
Abstract: An improved adsorbent comprising a crystalline aluminosilicate, method of manufacture of the adsorbent and improved process for separating a component from a feed mixture comprising an aqueous solution of a mixture of different components, such as a mixture of saccharides. In the process the mixture is contacted with the adsorbent, which selectively adsorbs a component from the feed mixture. The adsorbed component is then recovered by contacting the adsorbent with a desorbent material such as water to effect the desorption of the adsorbed component from the adsorbent. There is an undesirable tendency for the silicon constituent of the crystalline aluminosilicate to dissolve in the aqueous system. The improvement to the adsorbent and process comprises the incorporation of a binder material in the adsorbent comprising a water permeable organic polymer which substantially reduces the undesirable dissolution. The adsorbent is manufactured by mixing together powder of the crystalline aluminosilicate, powders of the organic polymer binder, and a liquid organic solvent, extruding the mixture into an extrudate and drying the extrudate.
