Abstract: An apparatus for removing yarn remnants from a cop tube, especially a cop tube located a caddy, includes a device for removing yarn remnants from the cop tube. An elastically deformable energy storing device is disposed in the vicinity of the bottom of the cop tube. A holder for the yarn remnant removing device is movable along the cop tube and toward the energy storing device for storing potential energy.

Abstract: In a structural element, in particular a facade element with an outside plate sandwich, in which solar cells are arranged between an outer plate and an inner plate, and with another internal plate, which is provided at a distance from the plate sandwich by means of a spacing frame defining the interior, the solar cells are embedded in a layer of casting resin; furthermore, the inner plate recedes in its dimensions in the region of at least one edge at least partially with respect to the corresponding edge of the outer plate and forms thus a recess that also reaches over the layer of casting resin and through which the necessary electrical lines are guided, whereby the recess in the direction of the interior of the structural element is covered by the spacing frame. As an alternative, the outer plate can recede with respect to the inner plate.

Abstract: A slip form for walls or chimneys including opposed frames each carrying form members, the opposed frames being adjustably tied together across the wall to be poured and further positioned and braced by scissor-arms extended between adjacent frames along the same side of the wall.
