Abstract: A viewing system for trains that makes real time visual information in the form of images or video of the vicinity of the end of a train available to a locomotive operator or distant user. The system gathers images or video of the vicinity of the end of a train and transmits and displays the images or video to a remote display on a locomotive or at a remote location off the train. The invention also records the images or video such that the images or video can be recalled and used at a later time.

Abstract: The present invention relates generally to a On-Demand Video Training and Self Analysis System and Analysis System, for use in (but not limited to): sports action training such as: golf, tennis, baseball, softball, table tennis, cricket, fencing, martial arts, gymnastics, as well as other types of action related training activity where technique and form may need to be reviewed and corrected as it is occurring. More specifically it relates to a single or multi camera video recording system for recording and analyzing action related real time events at the source. The On-Demand Video Training and Self Analysis System is unique in that it combines the best features of Video Training Systems and Instant Replay Systems, into a single system which allows the user to immediately see and self analyze his performance and correct deficiencies on the spot, and see the results of that correction immediately.

Abstract: A railroad coupler mount includes a hook (20) for contacting the inside upper lip (28) of a coupler head (10) within a single coring hole (12a), a jaw member (22) which engages the rib (18) between a pair of coring holes (12a and 14a), a pad (24) for abutting against an outside surface (26) of the coupler head (10), and a handle (30) for orienting the hook (20) in the transverse or upright positions. In a preferred configuration, end-of-train signalling and monitoring equipment (42) is connected to a railroad coupler mount (44) and the handle (64) which tightens the hook (58) against the inside lip of the coupler head also serves the function of locking a battery compartment door (54) closed.

Abstract: A pressure relief valve for a railway emergency brake system that is simple in construction, easy to manufacture and to assemble and that, in operation, is self-cleaning of brake pipe dirt and debris. The inventive valve comprises a valve body having a hollow space being divided by a diaphragm into a first and a second chamber. Chambers are coupled via an orifice in the diaphragm, coupling pressure from the first chamber to the second. The valve comprises a peg aligned with the orifice, penetrating and cleaning the latter when the diaphragm moves from a closed position into an open position.

Abstract: A motor driven ball valve may be driven in two modes of operation; those modes are a normal or testing mode and an emergency mode. The ball valve, when in its full open position, has an air passage that allows for the rapid exhaust of air in the air pipe of the air brake system to atmosphere, thereby inducing the emergency application of the brakes. The rotating ball valve assembly is capable of infinite variation between its full closed and its full open positions. Thus, the motor drive, which is remotely controlled, can effectively modulate the reduction in air pressure in the air pipe for a variety of purposes, including normal operation of the brakes and testing the air brake system. The motor drive mechanism may be in a cam, gear, or follower configuration. When an emergency application of the brakes is required, the motor drive mechanism is disengaged to allow a spring or other torsion device to rapidly rotate the ball to full open position, while drawing minimal electrical power.

Abstract: An improved railroad coupler mount (18) secures end of train signalling and monitoring equipment (40) to the coupler head (10) of the last car in a train. The coupler mount (18) is secured to the coupler head (10) by a banana shaped arm (20) which extends through relief holes (14a and 14b) in the guard arm side (12) of the coupler. A swivel toggle (22) positioned at the end of the arm (20) is pivoted to a perpendicular orientation relative to the arm (20) after it has been inserted through the relief holes (14a and 14b). A tightening screw (28) turned by knob (26) draws the arm (20) back out of the relief holes (14a and 14b) and causes the swivel toggle (22) to bear against the sidewall of the coupler head (10). A bulge (38) in the arm (20) is braced tightly against an inside wall of the coupler head (10) after tightening the arm (20).
