The coupling material adheres more tightly to the membrane than to the wafer. A portion of the bond between the ductile coupling layer and the membrane is broken during stretch so that the pellets adhere less tightly to the coupling layer following stretch than prior thereto.

Abstract: A pivotal bobbin support arm is under the influence of two spring elements. A first spring element is used to initially bias the support arm towards a friction drive drum during an initial phase of winding of a bobbin package and to thereafter biasing the arm away from the drive drum during a later phase of winding. The second spring element is a load reducing element which is secured to either the support arm or a frame element of the machine. This load reducing element biases the support arm away from the drive drum to counteract the contacting pressure of the bobbin package on the drive drum during winding. The load reducing spring element may be of composite structure or may be in the form of a flat spring. In either case the spring element is constructed so as to be manually mounted and detached without the use of tools.

Abstract: An anchor support for supporting a pipeline above the ground has a self-aligning support saddle that allows the pipeline to orient itself on the anchor support during construction to relieve stresses in the pipeline and to allow for variations from nominal pipeline elevation and angulation relative to the ground. The anchor support normally fixes the pipeline's position relative to the ground but also allows relative movement between the support and the pipeline upon occurrence of a seismic disturbance or other disturbance that would cause a dislocation of the pipeline and/or anchor support from its nominal position. The self-aligning support saddle, which includes a ball and socket connection for allowing the pipeline to orient itself over the saddle, is fastened to a shiftable subassembly that rests on a stationary base assembly affixed to one or more ground engaging vertical support members.
