Title: Hydraulic lifting arrangement for implements, especially on tractors
IPC: A01B63/114
Filed: 1980-10-24
Abstract: An improvement in apparatus for lifting an agricultural implement carried by a tractor provides for automatic rapid level adjustment of the implement relative to the terrain under control of a valve system which comprises a regulator valve controlling inlet flow to the pump responsive to a comparator valve carried by the implement. A continuous throtted flow from the regulating valve to the comparator valve is maintained at constant pressure tending to open a valve in the comparator while a sensor or feeler contacting the ground serves to effect a greater or lesser opposing force. A servo valve is provided which effects a back pressure acting together with feeler actuation. An equilibrium position of the valve determines the level to which the implement is changed, holding it constant on level ground until the feeler is actuated by encountering a rise or fall in the terrain. The construction provides for varying the elevation of an implement by either raising it or lowering it to meet rise or fall of terrain.

Patent ES-8404006-A1 (ES)
Title: Rotary drilling tool with percussion device
IPC: E21B4/14
Filed: 1983-07-07
Abstract: A hollow rotary drilling tool is equipped with a percussion device which comprises a nozzle comprising a cylindrical annular duct followed by a divergent annular duct. The divergent duct opens into flow paths, a central path and a peripheral path, through which drilling mud flows alternately in order to cause reciprocation of a percussion head located in the central path. The peripheral path joins the central path downstream of the percussion head. The external conical surface of the divergent duct is connected to the external cylindrical surface of the cylindrical duct via a radial step, which makes the flow in the peripheral path unstable, so that under normal conditions of flow the drilling mud flows along the central path. Flow along the central path is interrupted by contact of the percussion head with an abutment, which limits its movement in one direction, and which closes the central path, causing flow to switch to the peripheral path. This causes the percussion head to lift, opening the central path so that flow switches back to the central path.

Patent ES-8505388-A1 (ES)
Title: Process for the purification of polyisocyanates.
IPC: C07C263/20
Filed: 1984-08-10
Abstract: Crude polyisocyanates are purified by extraction at a temperature from 80 DEG to 180 DEG C. to form a two-phase system. The phases are separated and the phase made up of purified polyisocyanate and solvent is cooled to a temperature which is at least 50 DEG C. below the extraction temperature. Upon cooling, a second two-phase system forms. Purified polyisocyanate containing residual solvent is recovered upon separation of these phases. Solvent in which polyisocyanate is present that is reclaimed during this process may be reused in subsequent extractions. The purified polyisocyanates have a viscosity which is lower than that of crude polyisocyanates having substantially the same isocyanate content and average functionality. These purified polyisocyanates are useful in the production of polyurethane foams and moldings as well as adhesives and coatings.
