  • Non-powered shunting and track circuit disconnect mechanism for railway switch machine, railway switch machine and railway switching system including same
    Patent number: 11285979
    Abstract: A mechanism for use in a railway switch machine includes an elongate contact body having a housing formed from a non-conductive material, a plurality of electrical contact rails disposed in or on the contact body, and a contact block slidably coupled to the contact body such that the contact block can generally freely slide along the contact body. The contact block has a plurality of moveable contacts positioned thereon facing the contact body and is structured to engage a point detector bar of the railway switch machine. The contact block is moveable along the contact body from among: a first position in which a first and second rail of the plurality of contact rails are electrically connected and a third and fourth rail of the plurality of contact rails are electrically connected, and a second position in which only the second and third rails are electrically connected.

  • Output apparatus to output a vital output from two sources
    Patent number: 8289734
    Abstract: An output apparatus includes a first source of a first signal having a first state or a different second state; a second source of a second signal having a first state or a different second state; and a circuit structured to output a vital output including a first state when the first state of the first signal corresponds to the first state of the second signal and, otherwise, including a different second state. At least one of the first signal and the second signal is a static signal. The other one of the first signal having the first state and the second signal having the first state is a dynamic signal. When at least one of the first signal has the different second state of the first signal and the second signal has the different second state of the second signal, the vital output includes the different second state.
