Abstract: A transducer for use with a musical instrument to transmit vibrations from the instrument to an amplifier has a weight, at least one sensor connected to the weight, an insulating layer covering the weight and the sensor, a substrate layer covering the insulating layer, an attachment device for mounting the transducer to the musical instrument and a cable mounted to the bas for connecting the transducer to an amplifier. One conductor of the cable is mounted to the weight and a ground shield of the cable is connected to the substrate. The transducer translates surface vibrations of the instrument into electrical signals that can then be amplified or recorded. The transducer has superior tonal qualities.

Abstract: A radiation-heated fluidized-bed reactor and a process for producing high-purity polycrystalline silicon by using this reactor are provided. In this reactor, a heater device (14) is a radiation source for thermal radiation which is arranged outside the inner reactor tube and as a cylinder around the heater zone, without being in direct contact with the inner reactor tube. The inner reactor tube is designed in such a manner that it uses thermal radiation to heat the silicon particles in the heating zone to a temperature which is such that the reaction temperature is established in the reaction zone.

Abstract: A drive train with a torsional vibration damper and a torsionally flexible coupling is described, with the torsional vibration damper comprising a damping mass on the driven side which is resiliently supported with respect to a part (1) on the drive side and the torsionally flexible coupling comprising a damping mass on the drive side which is resiliently supported with respect to a part (11) on the driven side. In order to provide advantageous constructional conditions it is proposed that the torsionally flexible coupling and the torsional vibration damper are assembled into a modular unit with a common damping mass for the torsional vibration damper and the torsionally flexible coupling.

Abstract: The invention relates to a device for identifying defects during the feeding of a welding rod. A sensor assembly is located in the welding torch for detecting the feed pressure and the feed tension for the welding rod, a drive device for feeding the welding rod being located downstream of the sensor assembly in the feed direction of the welding rod (in the direction of the arrow).

Abstract: A chain lock for high-strength steel chains has two lock parts that are the same and can be joined together in a rotation-symmetry arrangement with one another, in the longitudinal direction. Each lock part has a longitudinal stay having arc segments that follow it at both ends. There are two coupling elements that are configured complementary to one another and are assigned to the two arc segments of each lock part. One of the elements is configured as a locking stay that follows the longitudinal extension of the lock part, and the other element is configured as a stay accommodation. The locking stay of the one lock part engages in the stay accommodation of the other lock part and rests against the complementary coupling surface of the stay accommodation with its coupling surface formed by the face end in the joining direction. The coupling surfaces comprise a coupling surface segment having a defined width, which has no curvature or only an insignificant curvature pointing in the joining direction.

Abstract: A buckle comprises a male portion and a female portion, the female portion having a top face, a bottom face and a cavity for accepting the male portion. The male portion is adapted to snap into the female portion to lock the two portions of the buckle together. At least one face of the female portion is formed from an integrally molded screen made of the same material as the rest of the female portion and having a thickness that is less than a thickness of the female portion. The screen reduces the weight of the buckle, making it more comfortable for the user as well as less expensive to manufacture.

Abstract: The invention relates to a filter arrangement for the separation of blood into plasma and cellular components, comprising at least one filter element with an inlet line and an outlet chamber in a closed housing, separated by a fine pore membrane. The inlet chamber is connected to an inlet line for donor blood an dan outlet line for cellular components and the outlet chamber is connected to an outlet line for plasma. The arrangement further comprises a device for the production of a backpressure in the filter element, whereby the fine pore membrane is in the form of a U-shaped bundle of n=650 hollow fibers of the type Micro PES-TF 10 from Akzo Faser AG, the ends of which are fixed in an air-tight and germ-tight manner to an aperture plate which seals the open end region of the housing, which is open at just one end, in an air-tight and germ-tight manner.

A plurality of glass capillaries (22) extend in the glass tube in the axial direction. The glass capillaries are fused to one another into an integral structure. The glass capillaries have air holes periodically arranged on a plane perpendicular to the axial direction, respectively.

Abstract: The invention relates to a method for measuring the concentration of substances in living organisms using microdialysis, whereby bodily fluid is mixed with a perfusate and passed through a membrane and a substance value is determined for the bodily fluid with the aid of a sensor unit. According to the invention, to allow for the limited transport through the membrane, so that the measured substance value differs from the actual substance value in the organism, a reference substance present in said organism with a known value is also measured after passing through the membrane and mixing with the perfusate and the actual substance value is determined, based on the quotient from the known reference substance value divided by the measured reference substance value, multiplied by the measured substance value.

Abstract: A buckle comprising a female part having a hollow body with a front wall, a back wall, an open top, a cavity between the top and bottom walls and at least one locking slot extending through the hollow body and communicating with the cavity. The top and bottom walls have a cutout that communicates with the open top. There is a male part that has a base, at least one locking leg and a central leg. The central leg has a shape that corresponds to the shape of the cutout in the female part. The central leg also has a mesh portion that reduces the weight of the buckle. Inserting the male part into the open top of the female part causes the central leg to rest in the cutout of the female part and the locking leg to engage the locking slot to lock the male part to the female part.
