Provided is an oscillation absorber for a structure, particularly a wind power plant, with a pendulum that is attachable to a component of the structure and a damper for dampening the motion of the pendulum, in which the pendulum passes through a containment ring that limits the deflection of the pendulum, wherein the containment ring is attachable to at least one wall of the structure.

The invention relates to a household electrical appliance for preparing food comprising a container (2) receiving a working tool (4) driven to rotate by a motor (6) and a lid (3) which detachably closes the container (2), the container (2) having a sensor element (8) cooperating with a safety device to prevent the motor (6) from operating when the lid (3) is not locked on the container (2), said sensor element (8) being movable between a rest position towards which it is brought by biasing means (81) and an operative position towards which it is moved by an actuating member (32) of the lid (3) when the latter is locked on the container (2), characterized in that the lid (3) comprises a skirt (31) extending over the entire peripheral circumference of the lid (3), the skirt (31) having an inner wall coming opposite an outer wall of the container (2) when the cover closes the container, and in that said actuating member (32) projects from the internal wall of the skirt (31) cover (3).

The invention discloses a sleeve compensator special for a thermal production well in petroleum industry. The sleeve compensator is connected in the tubular column of the sleeve of a thick oil thermalproduction well so as to provide effective compensation for the extension of the tubular column of the sleeve of the thermal production well which is caused by steam injection technology or the contraction of the tubular column which is caused by carbon dioxide injection and other measures and prevent the deformation damage of the sleeve caused by the extension or contraction. The sleeve compensator comprises an outer barrel and a central tube, the outer barrel is connected with a boot cap, the central tube is connected with the outer barrel through splines, a locking mechanism is arranged between the outer barrel and the central tube. The sleeve compensator of the invention has stable operation, simple structure, short tool length, low cost and long compensation distance, is applicable to the design of various thermal production well completion technologies, can be placed to any desired place and can not be affected by inclination. The sleeve compensator can ensure that when performing the steam injection of thick oil thermal production well, the completion string can be intact and not be damaged owning to the temperature change; no successive activity is needed to do after the construction and the inner drift diameter of the well is kept the same after well completion, thus providing good conditions for successive activity and construction.

An implant has a proximal protrusion that is distinctly non-round even in a worn state, e.g. square in cross section, and may include radial slots for use in threading the implant into the jaw bone. No forces need be applied directly to the protrusion's external surfaces when inserting the slotted implant for subsequent osseointegration.

Provided is a hydrofoil (100), in particular a rudder, for water- borne vessels, in particular ships, with a trailing edge (20), in which the negative effects of vortex formation in the direction of flow behind the hydrofoil, and/or of Karman vortex streets, are reduced, a projecting body (30) is arranged at the trailing edge (20) for the purpose of reducing vortex formation.

A weaving machine for producing a woven fabric has a shedding device to form a loom shed of warp material, a weft insertion device for inserting a preferably tape-shaped or band-shaped weft material into the loom shed, a drawing-off device for drawing off the finished fabric in a drawing-off direction, fabric movement device for moving the fabric back and forth in the warp direction to bring the last inserted weft material into contact with the binding point or fabric edge. A shed limiter device limits the opening of the loom shed from above and below the warp, and is movable back and forth in the warp direction. The shed limiter device only loosely bounds the fabric and essentially without actively clamping or pinching or contacting the fabric and/or the last inserted weft material, at least while moving in the direction opposite the drawing-off direction.

The invention belongs to a multi reaction chamber atomic layer deposition apparatus and a method, and belongs to the field of manufacturing equipment of semiconductors and processing technology. The atomic layer deposition apparatus comprises an A reaction chamber and a B reaction chamber, which are connected with a group of vacuum pumps through a transition chamber, the A reaction chamber and the B reaction chamber are reacted, the A reaction chamber and the B reaction chamber are respectively communicated with the reaction chambers and the transition chamber through channel valves, the reaction chambers are connected with a storeroom through a vacuum valve and a baffle of the storeroom, and an air inlet valve is arranged on the upper portion of the storeroom. The deposition method is that wafers of an integrated circuit are transferred back and forth between the A reaction chamber and the B reaction chamber through the channel valves, when transfers to the A reaction chamber, A phase reaction is produced, when transfers to the B reaction chamber, B phase reaction is produced, the A and the B phase reactions are conducted alternatively, and nanometer-thin layers or compound structure materials with thickness which is demanded by the integrated circuit are grown on each atomic layer of the surface of the wafers. The reaction chamber is less smirched, the deposition quality is improved, the reactant sources amount is saved, the process cost is reduced, and the environment hazard degree is lowest.

A gray cast iron brake disk (1) for a motor vehicle has a wear-reducing surface coating (6) applied thermally, for example, by flame spraying. The brake disk also includes an intermediate layer (5) of, for example, nickel. Due to its resilience, the intermediate layer reduces mechanical stress between the surface coating (6) and the brake disk (1).
