Abstract: The invention relates to a pair of hand-operated pliers (1), in particular pressing pliers, with jaws (6, 7) and hand levers (4, 5), wherein the jaws (6, 7) are pivotable around a preferably common rotational axis (x). Furthermore, one hand lever (5) is connected by a joint to one of the jaws (7), and a pressure support is located between the hand levers (4, 5) for the formation of a toggle (K). In order to further improve a tool of this type, particularly with respect to the design of the pressure support, it is proposed that the pressure support consist of a support roller (18) arranged on one hand lever (4), and of a curved section (19) which is attached to the other hand lever (5) and which works together with the support roller (18).

Abstract: The invention relates to a method and a registering system for the transfer of a jaw model in relation to a hinge axis, for example, in an articulator, and to a connection device for connecting a lower jaw adapter (1) to a measuring carrier (4), and a bite carrier (3) for producing a bite key. The invention is characterized in that the transfer of the mandibular joint geometry, especially the exact position of the hinge axis of the patient, can be carried out in a state of assembly or an articulator using only a hinge axis determination relative to the lower jaw of the patient. The transfer of the facial arc required until now in prior art is rendered superfluous by the invention. Moreover, the possibilities of use of the transfer in relation to the hinge axis are extended, modularised and simultaneously simplified and accelerated. Sources of error are eliminated, the expenditure on equipment and costs of the transfer of the model can be critically reduced.

Abstract: A spacer textile, particularly knitted spacer textile, has two cover plies spaced apart from one another, and spacer threads that connect the cover plies with one another. The cover plies are formed from a main thread system and a further thread system, forming courses that follow one another in the production direction. According to the invention, a first course is formed at least by the main thread system, and a second courses is formed by the further thread system. The thread or threads of the main thread system is/are guided without forming stitches, in the production direction, in the second course, and the cover plies have a lower tear strength there, when pulled in the production direction.

Abstract: A large manipulator, especially a truck-mounted concrete pump, has a boom base that can be arranged on a frame so as to be pivoted about a substantially vertical axis of rotation. The large manipulator has a pendular element, that hangs down as an articulated boom and a control device for controlling the drive units of the axes of articulation and rotation of the articulated boom. The remote control has at least one inclination sensor which is housed in a housing that is detachably fastened on the pendular element. Two inclination sensors are housed in the housing and are bent at an angle of 90° with respect to each other and with respect to an axis that is parallel to the pendular element axis. The housing has a mark indicating the orientation of at least one of the inclination sensors inside the housing.

Abstract: A device for generating light pulses includes a seed laser source for generating input light pulses. An optical pre-amplifier having variable gain receives the input light pulses from the seed laser source. An optical power amplifier receives the light pulses from the optical pre-amplifier and amplifies and compresses the received light pulses. The light pulses are compressed in the optical power amplifier in such a manner that the pulse duration of the output light pulses of the optical power amplifier is tunable via adjusting the gain of the optical pre-amplifier. Wavelength-tunable light pulses are obtained by supplying the output light pulses of the optical power amplifier to a highly non-linear optical fiber.

Abstract: The invention relates to a method for determining the gas quality of a sample gas mixed at least in part with biogas, having the main components CH4, CO2, N2, O2, H2, proceeding from a spectrum of the sample gas determined by means of infrared-spectroscopy measurement methods, under operating conditions, from which the mole ratios of the sample gas are determined by means of correlative methods, and converted to characteristic variables of the gas quality.

The contact includes an upper spring portion configured to press an upper surface of a plate-like connection target in a downward direction and a lower spring portion configured to press a lower surface of the plate-like connection target in an upward direction. The lower spring portion is deformable independently of the upper spring portion.

Abstract: A method for producing a lightweight, sound insulating covering (1, 1?, 1?, 1??) for a body component of a motor vehicle, in particular a lightweight dashboard covering, wherein the covering (1, 1?, 1?, 1??) is produced as a foamed, sound absorbing molded part in a single-stage operation by injecting a reactive mix, comprising polyol and isocyanate, into a cavity (11) of a foaming tool (9), wherein before and/or during the injecting, at least one predetermined surface portion (17), defining the cavity (11) of the foaming tool (9), is temperature-controlled in such a manner that the foamed molded part comprises an integral substantially pore free skin (1.1) with a thickness of at least 0.5 mm on one side, and comprises an open porous surface (1.2) and/or a thinner, sound permeable skin (1.4) on its side opposite to said skin (1.1).

Abstract: In the construction of walls in balloon framing below roof pitches, the attachment profiles need to be suitable for different inclines and are to be connectable to the incline. For this purpose, the attachment profiles have fastening tabs on both sides, which may be bent into the particular required inclined attitude. The fastening tabs extend nearly over the entire profile web and are only linked on a deflection edge on one side on the attachment profile in the area of the profile web. In addition, the attachment profile can be used for the upper and lower fixing of the sub profiles of a stud or stud round wall.
