Patent ES-371573-A1 (ES)
Title: Improvements in or relating to tools adapted for use in blind-riveting
IPC: B21J15/06
Filed: 1969-09-06
Abstract: A hydraulic intensifier 12 for a blind riveting tool comprises a sleeve 38 which is slidable relative to a hollow, stepped shaft 20 by air under pressure to cause hydraulic fluid to be forced through the shaft 20 from an annular chamber 46 formed between the sleeve 38 and shaft 20. When a valve spool (98) Fig.1 (not shown) on the riveting tool is depressed, air under pressure is admitted from a hose (100) to a hose 70 causing a piston 60 attached to the sleeve 38 to descend. Hydraulic fluid is thereby forced from the chamber 46, through passageways 47, 48 in the shaft 20, through a hose 90 and into a hydraulic cylinder (not shown) continuing a spring-biased piston which forms part of the pulling device for the rivet mandrel. When the spool (98) is released, the piston 60 is returned to its initial position. The shaft 20 is surrounded by a tube 21 between its one end and a sealing ring 56, and is provided in this area with flats (82) Fig.4 (not shown) so that the portion of the shaft 20 above the sealing ring 56 is open to atmosphere.

Patent ES-406448-A1 (ES)
Title: Manual labeling device
IPC: B41K3/36
Filed: 1972-09-06
Abstract: A device for imprinting characters on a belt or the like. A body and a lever are pivotally connected with a spring normally urging them apart. A pair of closely positioned rotary character imprinting members, carried on the body, receive the belt therebetween, the belt having the characters imprinted thereon by pressing the rotary members together. Means are provided for guiding the belt between the rotary members for the imprinting operation. One wheel engages the belt to drive it in response to the rotation of a drive wheel. The drive wheel is rotated after the body and lever have been moved or pressed together. A pin is rotatably and threadably received in the lever and has an enlarged upper head with an arm which operatively engages the drive wheel. When the lever and body are pressed together, the pin initially moves together with the lever. A platform is mounted on the body and movably receives the pin. When an appendage or stop element on the pin engages the belt after a selected translational movement of the pin has occurred, the stopping of the translational movement of the pin rotates the pin causing the arm to drive the drive wheel and thereby move the wheel which engages the belt to move the same a distance for having a character imprinted thereon. If no characters are to be imprinted, the spring returns the lever to the start position without imprinting. Alternatively, the lever is continued in its movement toward the body and the stop arm on the pin passes through a suitable opening in the platform permitting continued translational movement of the pin without rotation of the arm. After the characters have been imprinted by pressing, the spring returns the lever to the start position. The stop arm passes down through the opening in the platform and the drive arm moves below the drive wheel. When the enlarged head on the pin engages the platform, the rotary movement once again occurs and the pin and the drive arm are rotated back to the initial position, the drive arm being moved without engagement with the drive wheel.

Title: Method for recovering reaction gases from steel converters which are bottom blown with oxygen and cooled with hydrocarbons
IPC: C21C5/40
Filed: 1975-01-28
Abstract: This disclosure teaches a method for recovering reaction gases from a hydrocarbon-cooled converter which is bottom blown by oxygen. The converter comprises a vessel which is tippable between an upright position and an inclined position. The vessel is provided with bottom tuyeres and a cleaning system for the reaction gases. The method is characterized by the fact that, on tipping of the vessel, nitrogen is introduced instead of the oxygen through the bottom tuyeres whereby flushing of the cleaning system is effected. Detection means (preferably a gas analyzer) are provided to detect a predetermined increase in hydrogen content of the reaction gases during blowing and a setting ring is connectable to the vessel in sealed engagement with a suction line which forms part of the cleaning system. Control means are responsive to the detection means and are operable to connect the setting ring to the vessel and for tipping the vessel so as to flush the cleansing system. The setting ring has a labyrinth seal which permits entrance of a minor portion of air but assures a vacuum of -5 to -15 mm during the blowing.
Patent ES-435727-A1 (ES)
Title: Process for manufacturing of phosphoric acid
IPC: A23K1/175
Filed: 1975-03-18
Abstract: The invention relates to a process for the production of phosphoric acid containing calcium phosphates, i.e. Ca-containing phosphoric acid, by evaporating Ca-containing mother liquor from Odda process, whereby practically all the remaining nitrate and fluorine are removed in the form of HNO3, HF and SiF4, in which process the Ca-containing mother liquor is given a Ca/P weight ratio which is lower than 0.45 and is evaporated while recycling Ca-containing phosphoric acid, the recirculation being so controlled that the liquor has a phosphorus concentration during evaporation which is always adequate to prevent the liquor from forming a paste-like mass. Thus, it was discovered that the undesirable paste-like consistency experienced when calcium is present during evaporation can be avoided by controlling the phosphorus content. More particularly, it was found for most types of rock phosphate that the phosphorus concentration should be below about 15% by weight or above about 22% by weight in order to avoid the formation of a paste-like mass during evaporation of the liquor.

Title: Composite piston with protection of the fastening screws against corrosion by a coolant
IPC: F02F3/22
Filed: 1976-03-05
Abstract: A threaded cap screwed into the piston head with a sealed joint to a sleeve tube open and flanged at the other end are provided to encase the clamping screws that fasten the piston head and the upper piston body member and lower piston body member together. The casing thus formed shields the screws from possibly corrosive coolant that under operating conditions could work through the joints between the parts of a composite piston in spite of the clamping pressure of the screws. Each screw is screwed into the threaded cap at the piston head end and its head or a nut bears on the flange of the sleeve tube at the other end. The screws and their protective casings fit within bores in an annular strut forming a large part of the upper piston body member that butts against a low annular ridge on the underside of the piston head into which the end caps of the screw casings are screwed. A seal compressed between the annular ridge of the piston head and the annular strut of the piston body encircles each screw casing and a clearance space extending between this seal and the seal between the threaded cap and the sleeve tube is arranged to drain off any coolant that leaks into the first seal, so that it will not apply pressure to the second seal.
