  • Patent number: 10866195
    Abstract: A wheel integrity monitoring system for monitoring the integrity of a railcar wheel in an automated manner while the railcar is in operation (i.e., traveling) and comprising a light source that projects light onto the wheel and a light detector that detects the light reflected by the wheel. The wheel integrity monitoring system is configured to analyze the reflected light to determine if the wheel is defective.

  • Patent number: 10086852
    Abstract: An end-of-car system for railcars is provided comprising an asymmetric draft gear mechanism offering shock absorption to a railcar when the latter is subjected to buff or draft forces. The end-of-car system may be retrofitted to railcars having a different type of shock absorption system.

  • Patent number: 5474194
    Abstract: This relates to a color change system to be incorporated in a flexing area of an end panel of a closure. The color change system includes a dark background coating on a flexing portion of the closure end panel to which there is bonded by way of an adhesive such as a varnish, ink or coating a brittle layer which due to the flipping action of the flexing portion of the end panel will fracture. The brittle layer is preferably of a light color and is colored utilizing a fluorescent dye. The combination of the background color and the fluorescent color of the brittle layer produces a first color in the original closure and when the end panel flexes and the brittle layer fractures to not only crack but also tear apart or delaminate from itself, to reflect its own light color much more brilliantly, the color of the color change system drastically changes to indicate tampering. This color change is irreversible. The color change system may also include a message indicia.

  • Patent number: 5035341
    Abstract: This relates to a mechanically actuated closure cap which is provided with a tamper indicating feature. The closure cap includes an end panel having a centrally located button that is normally in a button down position, but when the closure cap is applied to a container, it is mechanically actuated to a button up position. A translucent panel is fixedly applied to the closure cap in overlying relation to the end panel and there is positioned between the button and the translucent panel several possibilities of devices for indicating that the closure cap has been applied to a container and either is in its original position relative to the container or has been removed therefrom.
