Abstract: Device incorporating retractable stops for limiting the flappings of the blades of the main rotor of a rotorcraft ABSTRACT OF THE DISCLOSURE          The invention relates to a device incorporating retractable stops for limiting the flappings of the blades of the main rotor of a rotorcraft. Each lower stop comprises a convex roller presenting a convex stop surface and bearing a weight at the end of an arm. By its convex roller, the lower stop is mounted to pivot about the pin for retaining the blade on the hub. On the ground, the bearing member is in contact with a lower bearing surface fast with the blade at the level of the pitch control lever, in order to limit the downward flappings of the blade. The lower stop pivots about the pin above the lower plate. The upward flappings of the blade may be limited by upper stops disposed substantially symmetrically below the upper plate. A second lower weight, returned by a spring, and engaging by a nose-shaped element in a notch in the rear of the bearing surface, acts as upper stop. The invention is more particularly applicable to equipping helicopters.

Abstract: ABSTRACT      Process for lift-off fabrication of sputtered dielec-tric or nonmagnetic gap materials and thin-film heads for either a single-element thin-film head or side-by-side el-ements on a thin-film head.   The  lift-off process uti-lizes  a  copper  coating  that  is  removed  by a  twenty percent solution of ammonium persulfate with a pH  n the range of seven to nine to assure complete removal of gap material from the back closure of the thin-film head with-out damage to the underlying permalloy.  The process can also be utilized to obtain a multiple layer deposits on a single thin-film had by repeating the steps of the pro-cess.  The process provides for a clean hole, no dielec-tric on the surface nor any attacking on the magnetick material.

Abstract: Abstract of the Disclosure A device for forming a tactilely readable display including Braille characters includes a planar display carrier wherein consisting essentially of a belt of flexible material which forms a closed loop and revolves about two rotating rolls.  Circular openings are provided on an outer side of the belt loop, the inner side of the belt being provided with a multiplicity of recesses communicating with respective openings in the outer side of the belt.  A steel ball may be lodged in each of the recesses, a portion of each ball protruding through the associated opening to form a spherical raster dot on the outer side of the belt.  An upper portion of the belt passes over a contact plate, which forms a reading zone of the Braille display device, while a lower portion of the loop passes through a steel ball container in which all of the recesses become occupied by a respective ball.  At a ball selection at an upstream end of the contact plate, as defined by the motion of the belt, an electromagnetically actuated selection device is disposed above the upper end of a guide channel extending downwardly from the selection station to the ball container.  The selection device selectively retains steel balls in the recesses of the belt during the passage thereof over the guide channel at the selection station.          Unretained steel balls fall back into the container via the guide channel.
