Patent ES-456761-A1 (ES)
Title: Filament feeding apparatus and method
IPC: B65H51/22
Filed: 1977-03-11
Abstract: A main array of main rods parallel to and centered on a fixed main axis is supported for rotation about this main axis. Similarly a skew array of skew rods substantially parallel to and centered on a skew axis extending at an acute angle to the main axis is supported for rotation about the skew axis with the skew rods interleaved with the main rods. At least one of the arrays of rods is carried on a support formed between the rods with throughgoing holes in which are loosely received the free ends of the other array of rods. Thus when either of the arrays of rods is rotated about its respective axis the free ends will operatively engage the support at these holes and rotationally entrain the other array, thereby rotating the main and skew arrays so as to define relatively inclined main and skew orbits. A filament is fed tangentially to the orbits and withdrawn tangentially therefrom, after being urged axially along these orbits by their relative inclinations. An eccentric is provided for varying the spacing of the skew axis relative to the main axis in a direction perpendicular to the main axis.

Title: Arrangement for controlled engagement of the tools of a mining machine with a mine face
IPC: E21C35/12
Filed: 1979-11-02
Abstract: An arrangement for controlled engagement of the tools of a coal planer, with a mine face comprises a scraper conveyor, provided on its front face directed toward the mine face with a guide rail guiding the coal planer for reciprocation along the mine face and a mechanism for tilting the conveyor and the coal planer about a substantially horizontal axis. The tilting mechanism is connected to the rear face of the conveyor and extends in its entirety rearwardly of the rear face of the latter. The tilting mechanism comprises a guide linkage pivotally connected at its front end to the rear face of the scraper conveyor while its rear end portion forms a housing for a fluid operated cylinder and piston unit, the piston rod of which is connected to a connecting rod guided by the guide linkage for movement in longitudinal direction and having an upwardly extending front section pivotally connected at its upper free end to the rear face of the scraper conveyor. The fluid operated cylinder-and-piston unit is thus considerably spaced from the scraper conveyor and the material transported thereby and especially coal dust raised during transport of the mined coal by the conveyor, whereby maintenance of the tilting unit is reduced. The guide linkage, the connecting rod and the tilting unit are all in close vicinity to the sole of the mine gallery to leave a considerable free space between the arrangement and the roof of the mine gallery.
