A transistor arrangement having a multiplicity of transistors interconnected with one another, having a noise detection device, which is set up for detecting the 1/f noise of at least one portion of the transistors, having a selection device, which is set up for selecting at least one of the transistors, on the basis of the ascertained 1/f noise characteristic of the transistors, in the case of which the 1/f noise is sufficiently low.

An optical system is described for scanning optical record carriers of different types. The optical system includes a compensator having a number of optical elements (NPS1, NPS2). The optical elements (NPS1, NPS2) are non-periodic phase structures (NPS) having annular areas separated by steps, forming a non-periodic pattern of optical paths of different lengths. By including these multiple optical elements (NPS 1, NPS2) having NPS surfaces in the lens system of an optical system, it is possible ...

An intravascular electrode arrangement 10 includes a first and a second electrode line 12, 14 adapted for placement in blood vessels such as veins or arteries, each having at least one stimulation and/or sensing electrode in the region of the distal end of the respective electrode line, wherein there are longitudinal guides 18, 18', 18'', 18''' provided externally on the first electrode line 12, 12', 12'', 12''' for the second electrode line 14.

A hinge arrangement including a living hinge adapted to movably connect two members to each other; and at least one plate spring adapted to connect to the two members. When the two members are in a folded position, the living hinge has a general "U" shape and the plate spring has a general "U" shape aligned with and generally overlapping the general "U" shape of the living hinge.

A transducer arrangement and method that generates control signals indicating relative positions of the ends of a hydraulically movable tool of a machine. The generated control signals of the present invention are used by a conventional control circuit of the machine to control the ends of the hydraulically movable tool having elevation receivers as an desired mode of operation or when reception by one of the elevational receivers of a elevational reference, which provides an absolute position o...

A valve arrangement includes a valve body defining an enclosure, having a bonnet connected to the valve body. A stem is rotatably attached to the valve body and positioned at least partially within the valve body. A handle is in operable communication with the stem and configured to rotate the stem. An actuation portion is positioned distal from the handle and in direct or indirect contact with the stem, wherein the actuation portion is configured to move when the stem is rotated. The stem inclu...

An insulator arrangement for supporting a conductor with an enclosure has an insulator fixedly connected at one end with the conductor. The insulator has another end portion mounted to a first shock absorber. The first shock absorber is further mounted with an access cover to permit displacement of the conductor and the insulator relative to the access cover. The insulator arrangement has second shock absorbers mounting the access cover to the enclosure permitting relative displacement between t...

A disc arrangement for a gas turbine engine, the disc arrangement including a rotational axis, a disc, a coverplate, and a retainer to retain association between the disc and the coverplate by interference. The retainer is displaceable in a recess of the disc or the coverplate to allow release of the interference. The recess presents the retainer at an inclined angle to the rotational axis for the disc and/or the coverplate.

A screening panel 10 comprises a peripheral frame 12 consisting of a pair of mutually laterally spaced side members 14, 16, which are integral with a pair of mutually axially spaced end members 18, 20. The side members 14, 16 and end members 18, 20 define corners of the panel 22.1, 22.2, 22.3 and 22.4 and the peripheral frame 12 where they meet. A plurality of mutually spaced ribs 15 extend across the periphery of the panel 10 to define a screening surface. The side members and end members are r...

A header arrangement has an elongated, lower, and substantially horizontal flange with a downwardly open U-shape for embracing a wall structured along at least part of the length of the lower flange, an elongated, and substantially vertical web connected along and extending upwardly from the lower flange, and an elongated, upper, and substantially horizontal flange connected along an upper edge of the vertical web and also having a U-shape. Web stiffeners and end stiffeners are engaged to the fl...
