Title: Draft sensing apparatus.
IPC: A01B63/112
Filed: 1980-06-25
Abstract: A draft sensing apparatus for an agricultural tractor or the like. The tractor is provided with a transversely extending bending shaft (18). The forward ends of a pair of lower draft links are secured to the outer ends of the shaft (18). The shaft (18) will bend in proportion to the draft in the links. The draft is sensed through a Hall effect device (52) carried by a yoke (54). The forward end of the yoke (54) is pivotally mounted on a fixed transversely extending shaft (48) and the rear portion of the yoke slideably receives the bending shaft (18). A link (60) pivoted to the yoke (54) has one end portion contacted by the shaft (18) and the other end is in contact with one end of a spring biased pin (70). The other end of the pin carries a permanent magnet (78) in axially alignment with the sensor (52). As the shaft deflects as the draft varies the magnet (78) will be shifted towards and away from the sensor (52) causing a voltage variation in line (98). By mounting the sensor (52) in the manner indicated the effect of vertical deflection of the bending shaft (18) will be reduced to insignificant levels as compared to horizontal deflection.

Patent ES-8200331-A1 (ES)
Title: After-treatment processes and apparatus, especially for urea and ammonium nitrate plants
IPC: C07C67/00
Filed: 1980-09-01
Abstract: Disclosed are after-treatment processes and apparatus for synthesis plants, particularly urea and ammonium nitrate plants, but applicable also to various other plants in which the synthesis reaction does not go to substantial completion. In such plants product is fed to an evaporator for concentration and then to a solidification stage. The vaporous overhead stream from the evaporator contains entrained synthesis product, one or more unreacted starting materials, and solvent (usually H2O). It is condensed, and the condensate is brought into mass and heat exchange relationship with the vaporous overhead stream from the evaporator substantially without material transfer of solvent to the condensate stream. The condensate stream is thereby enriched in synthesis product, heat is added to it, and unreacted starting material is desorbed from it. The product-enriched condensate is delivered to the solidification stage for processing there. Production capacity is increased and plant effluent is decreased or eliminated.
Patent ES-8106931-A1 (ES)
Title: Stabilized alkali metal percarbonate bleach compositions and process for manufacture thereof.
IPC: C11D7/54
Filed: 1980-08-12
Abstract: Powder bleaching compositions comprising sodium percarbonate are known and are desirable for textile treatment. However, sodium perborate tends to be used in many instances despite its cost and hazards in view of the relatively poor storage stability of sodium percarbonate. Various treatments to improve the stability of sodium percarbonate have been partially successful but have given rise to problems such as undesirable insoluble laundry residues, in the case of many coating treatments, and component separation on storage handling, in the case of separate stabilizing additives. The invention overcomes the prior art instability problems without these drawbacks by providing a bleaching composition in the form of particles of a mixture comprising sodium percarbonate and a phosphate compound stabilizer for the percarbonate. The percarbonate usually is present in sufficient quantity to provide 1% to 6% wt. available oxygen and the phosphate normally amounts to at least 2%wt.
