Abstract: Designs for a battery-powered, all-electric locomotive and related locomotive and train configurations are provided. In one particular exemplary embodiment, a locomotive may be driven by a plurality of traction motors powered exclusively by a battery assembly which preferably comprises rechargeable batteries or other energy storage means. The locomotive carries no internal combustion engine on board and receives no power during operation from any power source external to the locomotive. A battery management system monitors and equalizes the batteries to maintain a desired state of charge (SOC) and depth of discharge (DOD) for each battery. A brake system may be configured to prioritize a regenerative braking mechanism over an air braking mechanism so that substantial brake energy can be recovered to recharge the battery assembly. Many locomotive or train configurations involving battery-powered or battery-toting locomotive(s) may be implemented.

Abstract: A process for the continuous preparation of 4-amino-2,2,6,6-tetramethylpiperidine (TAD), comprising: passing triacetoneamine, ammonia and hydrogen over a catalyst of at least two layers in a reactor, wherein at least one catalyst layer comprises at least one element of the 4th, 5th, or 6th row of the 8th transition group of the Periodic Table or combinations of these metal elements on a suitable support, where the catalyst content with respect to each individual catalytically active element changes independently from the reactor inlet to the reactor outlet.

Abstract: A process for preparing 4-amino 2,2,6,6-tetramethylpiperidine (TAD) from 2,2,6,6-tetramethylpiperidone (TAA), ammonia and hydrogen using a cobalt or nickel catalyst on a support which allows the omission of any added solvent, and provides substantially simplified work-up and increased space-time yields by significantly reducing the amounts of excess ammonia and catalyst needed to accomplish the reaction.

Abstract: Methods and apparatus for inspecting surfaces are disclosed. The present invention provides a system which is particularly useful for inspecting the inner race of a bearing and uses two video probes to create dual displayed views of the inner surface. The bearing is slowly rotated and the entire surface of the inner race is visually inspected by viewing the images collected by the video probes. Preferably, a motorized stand and frame are provided that automatically rotate the bearing and automatically insert the video probes into the bearing respectively. The magnification provided by the video probes permits the detection of flaws invisible to the human eye, and in certain embodiments a scale on or adjacent to the video images is also provided so that the size of the defects viewed can also be accurately determined.

Abstract: A wheel chocking assembly that is especially suitable for securing a wide variety of automobiles to the deck of a railroad car includes a polyester strap member adapted to conform to the shape and extending over the top of an automobile's tire which is coupled to a pair of chock members formed as collapsible wedges and positioned in front of and behind the wheel. In one embodiment, the wedges are rotatably coupled to a pair of channels extending the length of the railroad car, and are collapsible for positioning of the automobiles during loading. Another embodiment utilizes a pair of wedges which are adjustably mounted in a telescopic fashion to frames extending inward from a channel attached to the deck of the railroad car at its sides, the channels being adapted to permit the frames to be swung up and out of the way during loading and unloading operations.
