A preform, and a container blown therefrom in a two stage process is disclosed having a loop defining a handle portion of the resulting blown container and wherein the loop is integrally connected by both a first end and a second end to respective first location and second location of the preform during manufacture of the preform. The lever has a flexible free end including a locking cam projecting out of the housing. Detection and cancellation in the frequency domain also provides a way of estimating the magnitude of the interfering signal, and hence also allows the wanted signal, at the frequency of the interfering signal, to be estimated. 2%, and the cord strength is in a range of from 2500 to 3500 Nsq. The message buffer is inserted into a message queue corresponding to a second process of the network component.
