Abstract: A connecting device which includes a socket member having at least two tines, the tines having an unstrained configuration from which at least one of the tines can be resiliently deformed away from the other tine to define a socket for receiving and holding a substrate, and a band of heat recoverable metal defining a driver member which in its martensitic phase loosely surrounds the tines so that at least one of the tines can be resiliently deformed outwardly when defining the socket member without deforming the driver member. The driver member when warmed to a temperature at which the metal is in its austenitic phase, recovers inwardly and exerts a supplementary inward force on the tines at least when the substrate is held in the socket. In the martensitic phase of the metal, the tines alone hold the substrate within the socket with sufficient force to provide a physical connection.

Abstract: A connector assembly providing uninterrupted protection against electromagnetic interference includes a receptacle having a recess in which a first contact assembly is positioned, and a plug having a mating portion which fits into the recess. The mating portion contains a second recess in which a second contact assembly is positioned to mate with the first contact assembly as it projects into the second recess from the first recess. Pivotally mounted doors within the first and second recesses protect the contact assemblies from radiation when unmated, and a spring contact between the mating portion of the plug and the walls of the first recess protect the contact assemblies from radiation during transition between unmated and mated conditions.

Abstract: A curtain supporting combination including a telescoping rod, ring and wall arrangement with elements including compression spring mechanism arranged to act in concert to mount the curtain and support and anchor the upper end of the curtain in close abutment with the wall at the end of the rod and at the same level as the main supporting level of the rod.

Abstract: An electrical connector member including a hollow housing member with an internal restricted passageway, an adjacent outer radial shoulder and a reference surface axially spaced from the shoulder oppositely to the passageway; and an insert member snugly retained against axial movement in first and opposite axial directions by said shoulder and surface, the insert member including a restraining surface in abutment with said shoulder, the restraining surface being shaped by plastic deformation of the weakened peripheral surface portion on the insert member by the wall of the restricted passageway during the final stages of the positioning of the insert member. The insert member before deformation includes the weakened peripheral surface portion formed by a plurality of axially extending knurls, and an adjacent protective collar which protects the weakened portion from deformation until the collar has passed through the restricted passageway and the insert member is in the final stage of positioning.
