Patent ES-460729-A1 (ES)
Title: Coupling apparatus
IPC: F16H3/54
Filed: 1977-07-14
Abstract: A two-speed transmission unit which couples a rotatable input shaft to a rotatable output shaft. A gear unit includes a sun gear fixed to the input shaft and rotatable therewith. One or more planet gears are disposed for orbital motion around the sun gear, and the planet gears are carried by a planet carrier which orbits with the planet gears about the sun gear. First clutch means is provided for coupling the sun gear to the output shaft for rotating the output shaft at a first angular velocity equal to the angular velocity of the sun gear, and second clutch means is provided for coupling the planet carrier to the output shaft for rotating the output shaft at a second angular velocity equal to the angular velocity of the planet carrier about the sun gear. Both the first and second clutch means are continually biased into engaged condition, and means are provided for (1) selectively placing one clutch means in a disengaged condition and allowing the biasing means to place the other in engaged condition, or (2) placing both clutch means in a disengaged condition, thereby allowing "free wheeling" of the input shaft. There is also provided a fail-safe brake to lock the input and output shafts against rotation when neither clutch means is placed in its disengaged condition.

Patent ES-477691-A1 (ES)
Title: Motor control circuits
IPC: H02P6/20
Filed: 1979-02-14
Abstract: In a brushless D.C. motor employing a permanent magnet rotor 1 and a two winding stator 2, 3 with electronic switching 4, 5 responsive to rotor position to improve efficiency, switching of the stator current is initiated in advance of the rotor reaching its neutral position so that the stator poles have more or less completed their change by the time the rotor reaches the neutral position. However, as, on starting, the rotor might therefore oscillate back and forth instead of rotating an override circuit 14 is included. When the rotor starts from a position between (in the desired direction of rotation) the point at which switching is initiated and the subsequent neutral axis 35, the override circuit 14 maintains the initial condition of the switching circuit for a predetermined period irrespective of the rotor sensor 35 output during that period.

Patent ES-8500121-A1 (ES)
Title: Method for facilitating the subsequent debarking of trunks by friction
IPC: B27L/
Filed: 1983-03-10
Abstract: It is possible to reduce the time required for debarking trunks by friction, for example for dry debarking in a drum for debarking trunks intended for conversion into wood pulp, by means of the prior processing (treatment) of the trunks. During combustion of the bark which has been removed, the latter must be as dry as possible. According to the present invention, the pretreatment, in particular of trunks which are difficult to debark, is improved in such a way that adhesion of the bark to the wood is greatly reduced without it being necessary to supply water to the trunks. This is achieved in that rigid beaters 9, which are joined in an articulated manner to a shaft 13 of a driven rotor which extends essentially transversely to the longitudinal direction of the trunks, are made to collide against the trunks 5 over an area and with an impact force which are sufficient to weaken the union between the bark and the wood through fatigue and/or transportation of moisture, induced mechanically, from the inner bark to a meristem layer which is located between the bark and the wood and which joins them together. The arrangement for pretreatment preferably includes at least one pair of rotors which has rotors 7, one above and one below, of a working width such that it is possible to process simultaneously a plurality of trunks placed side by side.
