Abstract: A tie-down device has been invented that greatly improves securement of cargoes, loads, and ladings to beds, supports, and pallets. When installed within post receiving wells of beds, supports, and pallets, compressable polymeric material is caused to latitudinally expand in all outwardly directions in response to longitudinally applied compression thereupon by turning of an eyenut member.

Abstract: An end equipment comprises a subscriber line interface, a communication controller, a demultiplexing circuit, a multichannel receiving circuit, a multiplexer and a network line interface. The demultiplexing circuit receives data words at a rate n.D from the subscriber line, whereby n is an integer between 1 and a maximum value N. The data words are multiplexed in n independent channels selected among N multiplexed channels in a telecommunications network link at rate N.D. Each of N channels has a basic rate D. During a setting-in and synchronizing phase of a communication, synchronization frame bits are transmitted in the n selected channels. In a multichannel receiving circuit, the synchronization bits in n reception channels of the network link are detected sequentially, and a synchronization is carried out channel by channel.
