Abstract: ABOVEGROUND ANCHOR SUPPORT ASSEMBLY FOR A PIPELINE 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 selfaligning 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.  After the pipeline is aligned, the ball and socket can be permanently interconnected to restrain any further movement of the pipeline relative to the shiftable subassembly. The shiftable subassembly is capable of moving relative to the base assembly in a direction generally parallel to the longitudinal dimension of the pipeline.  When a differential force is applied between the vertical support members and the pipeline, as can be caused by a seismic disturbance, the shiftable subassembly can move along with the anchor saddle and the pipeline relative to the base assembly, thereby preventing any substantial damage to the pipeline.  A restraining mechanism interconnects the shiftable subassembly with the base assembly to releasably restrain the shiftable subassembly upon application of a differential force of less than a predetermined magnitude.  Upon application of a predetermined differential force, the restraining mechanism releases the shiftable subassembly so that it can move relative to the base assembly.  Once the shiftable subassembly has begun to move relative to the base assembly, the restraining mechanism still applies a differential force opposing the movement.  After the shiftable subassembly has moved a predetermined distance relative to the base assembly, an energy absorbing member decelerates and stops the shiftable subassembly to prevent it or the remainder of the anchor support from becoming damaged.

Granted: 1981-07-28
Abstract: ABSTRACT OF THE DISCLOSURE        There is described an apparatus for registering quantity values of corresponding volume or energy quantities measured at consumption points at a distance from a central station which has a number of counters corresponding to the various consumption points.  Each time a predetermined volume or energy quantity has been measured, the corresponding signal transmitter is activated.          A signal is then relayed from the transmitter back to the central station where it is initially stored in a swift register device having a length equal to the number of transmitters coupled to the cental station.  Each of the transmitters is coupled to a dis-tributing device which selectively samples and couples each of the transmitters to the central station as they are activated.          Output signals from the swift register device emerge therefrom in synchronism with a subsequent activation of the transmitter to which they correspond.  The output signals are then coupled through a switch device to the corresponding counters.
