23	Railroad crossing gate control system including a separate maintenance relay	US994386	1997-12-19	US5852350A	1998-12-22	Donald L. LeVoir
A railroad crossing gate electrical control system for moving a crossing gate in up and down directions also provides for raising the gate counterweights in a failure mode. The control system includes an electric motor having a plurality of electromagnet poles and an armature rotating inside of the poles, with armature movement controlling gate movement. There is a motor and snub relay having contacts connected to the armature and the motor poles. A terminal board has movable contacts which are connected to the motor and snub relay and to a relay coil for moving the contacts of the snub relay. A source of power is connected to the terminal board. The movable terminal board contacts control the application of power to the motor and snub relay coil and the motor and snub relay contacts for operating the motor to cause up and down gate movement. There is a maintenance relay having a coil connected through a normally open switch to the source of power. The maintenance relay has contacts thereof connectable to the source of power and the motor, whereby closure of the normally open switch powers the maintenance relay coil to cause the contacts thereof to directly connect the source of power to the motor to cause the gate counterweights to be raised by armature movement.
24	Assault-resistant gate	US240537	1988-08-29	US4916859A	1990-04-17	Colin Butler
An assault-resistant gate is intended to bar passage, through an opening, of large vehicles moving at high velocity. The gate has a relatively strong hinge-post. A beam extends from the hinge-post across the opening. The beam is relatively rigid in a horizontal plane. The beam is attached to the hinge-post by a breakaway mounting. The attachment is weaker than the hinge-post. Energy absorbing material is disposed behind the beam on either side of the opening.
25	Railroad crossing gate	US292928	1989-01-03	US4897960A	1990-02-06	Todd A. Barvinek; James W. Jensen
An improved crossing gate for railroad grade crossings. The gate is constructed of an impact-resistant material, and the crossing arm is mounted so that it will swing out of the way and return to its original position if struck by a moving vehicle from either direction. The crossing arm also contains protected lighting that will withstand impact, and provision is made to permit easy replacement of burned-out light bulbs.
