A method in which at least one piezoceramic sensor, which converts every mechanical force to which it is subjected into an electrical signal and having a Curie temperature higher than 200° C., is solidarized directly onto the surface of a metal support element of a vehicle braking element, which during use faces a vehicle element to be braked. While in contact with such a surface, an electrical circuit is implemented that picks up and eventually processes the electrical signal, the electrical circuit being connected with a connector integrated with the metal support element. An electrically insulating layer sandwiches the at least one piezoceramic sensor and the electrical circuit, and a block of friction material with an underlying damping layer is formed upon the electrically insulating layer. After forming the block of friction material, the piezoceramic sensor is polarized by applying a predetermined potential difference thereto by means of the connector.

The invention relates to a construction method of an adobe wall suitable for a seismic fortification high-seismic-intensity area and adobes, and belongs to the technical field of constriction engineering. Multiple types of adobes are manufactured, and specific portions of the adobes are painted with water insulation and viscous energy consumption layers. The adobes are laid flatly in a joint staggering mode, two horizontal grooves and a plurality of vertical round holes penetrating through the full height of an adobe wall body are formed within an adobe wall layer high range, and vertical steel bars are embedded in strip foundations at the centers of the round holes. Longitudinal steel bars in the horizontal grooves hook the vertical steel bars in the vertical round holes in the ends of the adobe wall. Adobe wall sedimentation buffer areas are arranged at the intersections of the horizontal grooves and the vertical round holes of the adobe wall. Concrete is poured into the vertical round holes to form embedded columns, and concrete is poured into the positions, outside the sedimentation buffer areas, of the grooves to form embedded ring beams. After adobe wall body sedimentation is stable, the sedimentation buffer areas are filled with concrete, and the embedded ring beams and the embedded columns constitute ferroconcrete reinforcement grids in the adobe wall. The adobes play a role in reinforcing the whole adobe wall and remarkably enhancing seismic capacity.

A delivery device for stacking cut flat articles such as rotary cross cut sheets has a braking table downstream of a sheet feeder which is provided with two counterrotating disks which are perforated and communicate with suction passages on the table beneath the disks to brake the sheets as they are supplied to a stacker. At the edge of this table, there is a broad slit nozzle directing a sheet of air upwardly onto the underside of the sheets which are delivered to the stacker.

An elastic shaft coupling has one of the metal parts embedded in the elastic coupling ring and vulcanized thereto, split into two segments which are held together by a fixing element wholly within those metal segments in the form of a clamping ring or centering ring or both traversed by a screw threaded into the driving or driven member of the coupling.
