Abstract: An expansion dowel assembly includes an axially elongated anchor bolt and a pair of serially arranged expansion elements or shells into which the anchor bolt is drawn. The anchor bolt has axially extending conically shaped expansion members spaced apart in the axial direction and each is arranged to be drawn into a different one of the expansion elements. The expansion member closer to the leading end of the anchor bolt has a larger cone angle than the other expansion member. The expansion elements are interconnected by a web so that the expansion elements are axially displaceable relative to one another. When the anchor bolt with its expansion members is drawn into the expansion elements, initially the trailing expansion element is widened or expanded. Subsequently, after a predetermined axial movement of the leading expansion element toward the trailing expansion element, the widening of the leading expansion element is commenced.

Granted: 1994-12-28
Abstract: Dispositif à semi-conducteur (10) à puits quantique unique, dans lequel une couche centrale (12) est disposée entre deux couches barrières (14) pour former une barrière quantique (15), les couches barrières (14) ayant une composition telle qu'un niveau d'énergie de résonance (18) soit engendré dans la couche (12) à puits quantique, et dont l'épaisseur est suffisamment faible pour que les électrons puissent migrer à travers la barrière quantique (15) lors de l'application d'une tension. La couche (12) à puits quantique et les couches barrières (14) sont disposées entre deux couches (16a, 16b) à injection d'électrons dont les compositions sont choisies de manière que l'énergie minimale de la bande de conduction (20) pour les électrons se trouvant dans les couches à injection soit environ égale mais inférieure au niveau de l'énergie de résonance (18) du puits quantique (12). Les électrons traversent la barrière quantique (15) sous l'effet tunnel lorsqu'une faible tension est appliquée aux deux bornes principales du dispositif, pourvu que cette tension soit suffisante pour que les électrons dont l'énergie est voisine de l'énergie minimale (20) de la bande de conduction de la couche à injection (16a) passe au niveau d'énergie de résonance (18) du puits quantique. La tension interne (Va) nécessaire pour réaliser l'effet tunnel est réduite par rapport à celle requise pour les diodes à effet tunnel à double barrière classiques. On obtient ainsi un courant plus élevé sous l'effet tunnel et un rapport amélioré de courant maximum/minimum sur la plage des résistances négatives, et la tension du point de fonctionnement à courant continu est réduite. Le dispositif à semi-conducteur (10) peut être muni de deux ou de trois bornes, une borne étant prévue pour l'application d'une tension à la barrière quantique (15).

Title: Expansion dowel
IPC: F16B13/08
Filed: 1988-07-27
Granted: 1992-03-11
Abstract: The expansion dowel, consisting of an anchor bolt (1) and an expansion sleeve (2), is radially enlarged by driving the expansion sleeve (2) onto a broadening (1e) of the anchor bolt (1), and is anchored in the drilled hole. The broadening (1e), designed as a concave bulge, results in an increasing conicity in the insertion direction, as a result of which the subsequent expansion of the expansion dowel is limited. Cutting teeth (2d, 2e, 2f), which are arranged on the front end region of the expansion sleeve (2) and have a saw-tooth-shaped profile, deposit a proportion of the retention material on the wall of the drilled hole, when the expansion sleeve is driven forward, and thus create an undercut. In order to attain easier deformability, the expansion sleeve (2) is provided on its outer side with a ring slot (2g) in the region adjacent to the cutting teeth (2d, 2e, 2f) in the direction opposite to the insertion direction.

Abstract: A thermal blanket (10) includes an inflatable covering with a head end (12), a foot end (14), two edges (15) and an undersurface. The covering is inflated through an inlet (16) at the foot end (14) by a thermally-controlled inflating medium. An aperture array on the undersurface of the covering exhausts the thermally-controlled inflating medium from the covering. Exhaust port openings (23) are provided at the edges (15) of the covering to vent the inflating medium, which enhances circulation of the thermally-controlled medium through the cover. An uninflatable section (22) is provided at the head end (12), together with an absorbent bib (24) attached to the covering, adjacent the uninflatable section (22). When inflated, the thermal blanket (10) self-erects and provides a bath of thermally-controlled inflating medium to the interior of the erected structure. The enhanced circulation of the medium through the covers maintains a relatively high average temperature under the blanket (10) and a relatively uniform distribution of temperature in the inflating medium which is exhausted through the apertures into the structure's interior. When the structure covers a patient, the uninflatable section (22) provides a relatively unobstructed view of the patient's face, while the absorbent bib (24) maintains a relatively sanitary environment in the area beneath the patient's head.

Abstract: A network in which not only the transmission of control signals and information signals in transmission sections (1, 1a), but also the switching in switching devices (24) and the joining or the separation of the control signals and information signals take place in the optical domain. The control signals (c) and the information signals (d) in the optical domain are distinguishable from each other, and they are both coupled in and out in one and the same optical conductor (1, 1a). For distinguishing the control signal from the information signal the transmission modes (e.g. the wavelength or the polarization mode) thereof can be different. A distinction between the control signal and the information signal can also be effected by opposite directions of transmission; for controlling a switching device a control signal is then transmitted to the switching device via a glass fibre which at the same time serves for the transmission of information signals in an opposite direction.
