Abstract: A method, system and computer program product records missed information that is communicated between one or more connected communication terminals during a disconnection period and replays the missed information when a temporarily-disconnected communication terminal reconnects to the active communication session. The method comprises: detecting disconnection of the communication terminal from the active communication session; in response to detecting the disconnection, automatically recording the missed information exchanged between the one or more connected communication terminals remaining in the active communication session; detecting reconnection of the disconnected terminal to the active communication session; and delivering the recorded information exchange to the reconnected terminal, in response to detecting the reconnection.

Abstract: The sound attenuation of building partitions having a cavity between opposing panels thereof is enhanced by a bowed blanket of mineral fibers in said cavity. The apex of the bow is in compressive contact with one of the panels so that sound waves passing into a panel are dampened before they reach the panel on the opposite side of the partition. The bowed blanket is particularly effective in the frequency range wherein the coincidence effect is troublesome.

Abstract: A resilient sheet metal runner for attaching wallboard to a supporting structure comprising a base attaching flange having a resilient web coextensive therewith and integral with a longitudinal edge thereof with a support portion integral with an opposite edge of the resilient web and a stop flange integral with the opposite edge of the support portion. The base flange is disposed in a first plane, the flexible web is disposed in a second plane at an obtuse angle to that of the base flange and with respect to a third plane represented by the support portion. The stop flange extends at an obtuse angle toward the first plane in a fourth plane which it occupies but is of less width than the resilient web so that it does not extend into the first plane.
