Title: Production of metallic articles
IPC: B21D22/20
Filed: 1975-05-13
Abstract: Alloys having a composition suitable for superplastic deformation usually require heat treatment after casting and mechanical working in order to produce in the alloy the necessary fineness of grain stucture to permit such deformation to occur. It has now been found that some such alloys including in particular ranges of aluminum alloys containing zirconium (or Nb, Ta or Ni) may be heated to a superplastic forming temperature and non-superplastically deformed at that temperature to induce dynamic recrystallisation and simultaneously produce a fine recrystallised grain structure and superplastic deformation.

Patent ES-474082-A1 (ES)
Title: Stepless variable stroke drive having a non-rotating cam
IPC: B62M9/08
Filed: 1978-09-25
Abstract: A stepless variable stroke drive particularly suitable for a bicycle transmission has a crank driven input element comprising a carrier housing journaled for rotation on a spindle. Mounted within the carrier, journaled on individual axles, radially spaced to the spindle, are four planet gears which engage an output sun gear. Recessed into one side of each planet gear is a concentric channel whose outer circumference is constructed with ratchet teeth and whose inner circumference journals a crank ring having pawls for engaging the ratchet teeth. The ring also has a follower which engages a cylindrical cam channel fixed on and adjustable to various eccentricities relative to the spindle. As the carrier housing rotates, the crank ring follower engages the cam channel causing the crank rings to angularly oscillate at an amplitude proportional to the cam channel eccentricity. Sequential intermittent engagement of the crank ring pawls with the planet gear ratchet teeth during a portion of each carrier revolution drives the sun gear at a constant speed which is a multiple of the input speed dependent on the cam eccentricity. In another embodiment, the crank ring is eliminated and the planet gears each have a follower for engaging the eccentric cam channel. The carrier housing has slots for the planet gear axles which allow the planet gear to sequentially move to engage and disengage the sun gear for a selected portion of each planet gear's oscillation to accomplish a speed increase, decrease or reversal. Alternate manual and automatic controls are provided for both embodiments to adjust the cam channel eccentricity.

Patent ES-484282-A1 (ES)
Title: Deflection circuit
IPC: H03K4/83
Filed: 1979-09-19
Abstract: A trace current is generated in a horizontal deflection winding upon closure of a trace switch. A retrace capacitor forms a resonant retrace circuit with the deflection winding upon open-circuiting of the trace switch. A second resonant circuit is coupled to an energy supply and stores energy when the trace switch is closed. A second switch couples the resonant retrace circuit to the second resonant circuit during retrace. The stored energy in the second resonant circuit is then transferred to the resonant retrace circuit and to other load circuits, such as a flyback transformer.

Patent ES-8102052-A1 (ES)
Title: Apparatus for moving and orienting bottles.
IPC: B65G47/14
Filed: 1980-04-01
Abstract: Bottle handling apparatus receives bottles from a dispenser to a first transport region (34) between two parallel conveyor belts (such as 38) which grip the bottle between them. The bottles are arranged in a random sequence of top-leading and top-trailing bottles. Bottles are transferred from the first transport region (34) to a second transport region (36) in the form of two further parallel conveyor belts (such as 86) overlapping and located beneath the first transport region. The belts in the second transport region grip the bottles more firmly than those in the first transport region, taking over control of the bottles and accelerating them away from the first transport region. From the second transparent region the bottles are delivered to a discharge wheel (32). In the transition zone between the first and second transport regions means are provided for changing the disposition of top-leading bottles to a top-trailing disposition, while not interfering with the position of bottles already in the top-trailing position. In one embodiment the means includes a hook (158) engaging the open leading end and holding the bottle so that the bottle pivots around the hook under the action of the belts to reverse the disposition of the bottles. In a second embodiment the bottle is engaged by cam surfaces which have the effect of turning any bottles in top-end leading disposition to an top-end trailing disposition.
