The present invention relates to novel processes for preparing borylsilylamines, novel amines, novel borosilazane compounds, novel oligoborosilazane or polyborosilazane compounds which have the structural feature Si\u2014N\u2014B, ceramic material and methods of producing and using them. The composite dielectric structure comprises FSG, undoped silicon oxide, silicon-rich silicon oxide and silicon nitride. The identifier is transmitted to a host computer system having a record of the identifier and a status of the ticket. Identified dangling pointer may be reported to the end user. A pivot plate having first, second and third connectors pivotally attach the frame to the bed and to each other, and when actuated by a linear extensible actuator provides the necessary force for moving the bed relative to the frame of the trailer up and down between trailing and loading positions.
