Abstract: A tube spinner for assembling vehicle tie rod assemblies is disclosed. The tube spinner includes a support structure for supporting a tapped tube, a rotating device for rotating the tube within the support structure into threaded engagement with one or more sockets simultaneously and a restraining structure for locking the sockets against rotation. In a preferred embodiment, a plurality of casters are provided for supporting a tube along a main axis of the tube. Generally U-shaped tracks are placed adjacent left and right ends of the tube to prevent rotation of sockets being attached to the left and right ends of the tube. A motor driven friction wheel is brought into engagement with an outer circumference of the tube for rotating the tube along its main axis and simultaneously threading the tube onto one or more sockets.

Abstract: A vibrator baseplate for use in a seismic signal transducer system has a bottom plate with a dome centrally located thereon. A pair of partial domes overlap the central dome on opposite sides thereof. Top plates are attached to the partial domes, which are also attached to the bottom plate. Internal rib stiffeners are provided within each dome and gusset members extend between the partial domes and the top plates. Means are provided to connect the baseplate to the seismic signal transducer system. Alternatively, the baseplate comprises a bottom plate with an elongate eccentric dome attached thereto.
