Abstract: There is described a control peripheral post of railway field devices, comprising: —at least one row of control modules operatively connected or connectable by electric cables to field devices; —a support frame having a front side and housing said row of control modules; wherein said support frame comprises at least one anti-extraction bar positioned on the front side of the support frame, said bar being adapted to selectively take an extraction configuration, wherein said bar is positioned in such a way as to permit the extraction of the control modules from the front side of the support frame, and a blocking configuration, wherein said bar is positioned in front of said row of control modules so as to prevent the extraction of the control modules (4, 5) of said row from the front side of the support frame.

Abstract: A storage and retrieval system primarily adapted for the convenient storage and retrieval of media disks includes a plurality of disk enclosures releaseably supported in a hanging fashion from a rod via a plurality of hanger assemblies. The rod has a plurality of grooves and the hanger assemblies have at least two inwardly extending tabs that engage the grooves. The hanger assemblies have an upper section that includes the tabs, and an elongate docking member attached to and disposed below the upper section. The docking member includes a generally downwardly opening channel having a wider main section disposed above a constricted section. The disk enclosures each have a generally elongate docking section that are adapted to releasably engage the docking member such that the disk enclosures are releasably supported in a hanging fashion from the rod with limited rotational movement about the axis of the rod.

Abstract: An organizer for orientation of desk top items includes a frame, having a front, back and two sides, for receiving a plurality of modules, orienting the modules vertically within the frame between to two sides and enabling access to the modules from the frame front and a plurality of modules and a bracket for attaching one of the frame sides to a generally vertical surface. The bracket includes a body for engaging the frame, a bendable tab extending from a top of said body for attaching said body to a top of the computer monitor, and a rear tab, hingeably attached to a rear of said body, for attaching said body rear to a side of the computer monitor, the hingeable attachment enabling stabilization of the body rear at a spaced apart relationship with the computer monitor side. One of the modules may include interface connections for contact with a computer.
