Abstract: An inserted device for connecting auxiliary storage units (2) to a data-processing assembly, the units being connected on the one hand by a daisy-chain control cable A connecting the storage units (2) to one another and to the data-processing assembly, inter alia to at least one auxiliary storage unit controller (3), and on the other hand by high transmission-speed star cables B, characterized in that it comprises means for disconnecting and connecting each auxiliary storage unit (2) in the data-processing assembly without interfering with the operation of the other auxiliary storage units (2), inter alia those connected to the same controller (3).

Abstract: The cove fixture described herein is formed of an extruded elongated trough body having a series of grooves on the inner face of its side walls, an additional wall extends upwardly from within the body and includes also a groove longitudinally thereof. A fluorescent supporting plate is slidably mounted in the grooves so that one or more fluorescent lamp may be longitudinally adjusted in the body to provide optimum light distribution over the wall of a room where the light fixture is mounted.

Abstract: A light assembly for mounting to a synoptic display panel is composed of a tile having a transparent surface portion, of a light-conducting transparent body, having at one end thereof adjacent to the tile, a diffusion surface, of a hollow block with baffles dividing the block into chambers in which are disposed light elements, and of a transparent plate mounted between the baffles housing and the transparent body; the transparent plate displays a geometrical pattern of colored areas, each area corresponding in shape to the cross-sectional area of a chamber with which it is in registry so that the light emitted from one of the light elements is colored by the area registered therewith, transmitted through the light-conducting body to the diffusion surface and emerges from the transparent surface portion of the tile.
