Abstract: The invention relates to a hand-held power tool, especially a rotary hammer and/or chisel hammer. The hand-held power tool is provided with a vibration dampening unit having a first absorber mass unit with a first vibration dampening direction and at least one second absorber mass unit with a second vibration dampening direction. The hand-held power tool in particular has the first vibration dampening direction of the first absorber mass unit disposed as substantially parallel to the second vibration dampening direction of the second absorber mass unit.

Abstract: The invention relates to a wobble drive of a hand-held machine tool, particularly a drilling or chipping hammer, having a drive shaft, a wobble bearing disposed on the drive shaft, and a wobble plate supported on the wobble bearing. At least two wobble fingers having wobble finger axes being provided on the wobble plate. The invention provides that the axes of the wobble fingers form an angle different from 180°.

Abstract: The invention is based on a hammer drill and/or chisel hammer, having an impact mechanism unit, an impact mechanism housing and at least one damping unit. The invention proposes that the damping unit is arranged on the impact mechanism housing along a main extension direction of the impact mechanism unit.

Abstract: The method is used to produce a set of dentures for an untoothed or partially toothed jaw for dental care of patients, especially a set of dentures which are to be placed on implants that are to be newly fixed. Initially positioning screws provided with a capping element are inserted in the lingual-oral or palatinal region and/or on the crest of the jaw. A cast (6) is made, expressing the real situation of the jaw of the patient including the positioning screws (8). Corresponding positioning screws (8) are then inserted into the cast (6). Other technical work is carried out on the cast (6), i.e. a drilling jig (7) is manufactured for the implants to be positioned and/or a transfer jig is manufactured, in additional to dental work carried out in the mouth of the patient, i.e. the drilling jig (7) is used to position the implants and/or to block the supports for the implants with the transfer jig by respectively fixing them on the positioning screws (8) in the cast (6) or jaw.

Abstract: The thermoactive wall and ceiling element is installed in walls of newly built and old buildings and serves for its heating and cooling. It consists of a closed casing (2) which for intermediately storing heat comprises a phase change material (3) which melts when accommodating heat and reversely delivers latent heat to the surrounding on solidification. A lamellar design (8) with sound-absorbing material (4) therebetween is hung on this casing in a thermally separated manner by way of a heat-insulating material. At the bottom the lamellar design (9) is closed by a perforated ceiling sheet [metal] (plate) (5) in a heat-conducting manner, and this sheet metal (plate) forms the viewed ceiling of the room. The lamellar design encloses a heating and cooling pipe which is outwardly formed by the lamellar design as one piece or is connected to it is a heat-conducting manner.
