Patent ES-391702-A1 (ES)
Title: Scrubbing apparatus for polluted gases
IPC: F23J15/04
Filed: 1971-05-28
Abstract: A liquid screen scrubbing apparatus for effectively and efficiently removing insoluble and soluble solid, liquid and gaseous pollutants and materials valuable for by-product recovery from gases such as products of combustion and other atmospheres of industrial processes. The apparatus is located in a flue between one or more sources of polluted gases and a point of discharge, the apparatus including longitudinally spaced rows of vertically disposed elongated tanks, the rows extending transversely of the flue. The tanks in a row are angularly oriented and spaced from each other, and the tanks in adjacent rows are staggered. Each tank is crescent-shaped in horizontal cross section, and the concave wall thereof faces generally upstream toward the gas source. Liquid such as water continuously flows down the concave upstream walls of the tanks forming liquid screens, and when gases moving through the flue impinge on the flowing liquid, the insoluble and soluble pollutants such as dust, liquid droplets, SO2, SO3, Co, etc. and by product materials are entrained or dissolved in, and carried away by, the liquid. The tanks may be mounted for rotation on vertical axes, and thus subject to variation of the angular orientation in the manner of an adjustable damper between substantially closed position and desired open positions. The gases have tortuous travel paths through the apparatus, and the paths and pressure drop in the apparatus are determined by the angular orientation of the tanks. There are optimum angular settings for the crescent-shaped tanks to provide the most efficient removal of the solid and soluble pollutants and by-product materials of given gases under given conditions of gas velocity.

Patent ES-433279-A1 (ES)
Title: Production of a clean methane-rich fuel gas from high-sulfur containing hydrocarbonaceous materials
IPC: C01B3/22
Filed: 1974-12-23
Abstract: This is an improved process for converting low-cost high-sulfur containing hydrocarbonaceous materials into a clean methane-rich gas stream which may be burned as a fuel without contaminating the atmosphere. A high-sulfur hydrocarbonaceous fuel is gasified by partial oxidation to produce a process gas stream which is cooled, cleaned and subjected to catalytic methanation over a sulfur-resistant catalyst comprising 0.8 to 10 atoms of an element selected from the group comprising Co, Cr, W or mixtures thereof per atom of an element selected from the group Mo, Ni, or mixtures thereof. The catalyst may be supported on a structure formed from Group III and IV elements e.g. alumina, silica stabilized alumina, zeolite. A distinct advantage of the subject process, is that the sulfur in the process gas stream is not removed prior to the methanation step. Rather, the sulfur is permitted to remain in the process gas stream in order to moderate the highly exothermic methanation reaction. After cooling and purification by removing one or more members of the group H2, CO, H2O, CO2, COS, H2S, Ar, and N2, the resulting methane-rich gas stream comprises about 10 to 95 mole % CH 4. Optionally, the CH4 content of said methane-rich gas stream may be increased to about 98 mole % or more by the additional steps of water-gas shift conversion, catalytic methanation, cooling, drying and CO2 removal. The product gas would then have a gross heating value of about 1000 BTU/SCF.

Patent ES-452966-A1 (ES)
Title: Inverter transformer
IPC: H01F19/08
Filed: 1976-11-03
Abstract: A transformer designed to operate with a pair of power switching transistors in a d.c. to a.c. inverter is described. The transformer has an assembled core whose closed magnetic path is branched. A flux steering winding is used to ensure the prior saturation of a first branch associated with a regenerative feedback winding. Prior saturation of this branch reduces the forward drive on the switching transistors prior to full core saturation and avoids the consequent switching stresses on the transistors. The cores of the transformer are made from parts which abut at the branches so that both preformed power and preformed control windings may be used in assembling the transformer. The transformer may be assembled from conventional core configurations, and is thus of relatively low cost. A core arrangement is also disclosed in which the cross-section of the individual branches of the core may be adjusted.
Patent ES-455330-A1 (ES)
Title: Strap tensioning tool with load-sensing handle
IPC: F16H7/08
Filed: 1977-01-25
Abstract: A strap tensioning tool having a feed wheel driven through a tensioning assembly by a load-sensing handle. The feed wheel and tensioning assembly are mounted in a frame for pivotally swinging from a first position in which tension can be drawn on a strap loop by the feed wheel to a second position in which tension cannot be drawn by the feed wheel and whereby the strap can be inserted into, or removed from the tool. The load-sensing handle has a drive lever which is rotated to drive the feed wheel by a handle lever pivotally mounted on the drive lever, whereby the feed wheel can be rotated to achieve a certain predetermined strap tension, after which the handle lever overcomes the force of a biasing means between the handle lever and drive lever and moves relative to the drive lever about the pivotal mount until the handle lever contacts fixed stop means preventing further rotation of the handle lever to thus stop the tensioning action.
