  • Tie plate track fastener feeder
    Patent number: 5542355
    Abstract: A rail spike feeder, which may feed regular spikes, hairpin or lock spikes, and coach screws, uses a holder which receives spikes from a spike chute. The spikes do not assume any secure position from exiting the spike chute until after contact with the holder. The holder uses a four bar linkage arrangement such that the holder pivots about ends of first and second links at the same time the opposite ends of the links are swinging or pivoting about their mounts. This maintains a proper orientation for spikes moved into a spiking position whereat a spiker head, such as a spike hammer, may insert the spikes into tie plates and ties. A counterweighted finger assembly is used to maintain spike orientation as spikes are transferred from the spike chute to the holder.

  • Linkage device for mounting swather header
    Patent number: 5535578
    Abstract: A levelling mechanism for use a in lift system of a windrowing machine of the type including a tractor unit and a swather header to permit the use of a grain header which is held suspended above the ground rather than a hay type swather header which normally engages the ground during cutting. The type of lift systems used in some known hay windrowers include a pair of lift assemblies each of which has a single action lift cylinder. The two cylinders are supplied from a common supply line, and because the moving lift components of the two assemblies are individually activated by their respective cylinders the suspended grain header does not remain levelled under certain conditions, such as if there is a build up of greater crop weight at one end relative to the other.

  • Neural network system having dynamically reconfigurable connections
    Patent number: 5533169
    Abstract: A neural network system is provided that includes a network of neural operators pilot controlled by a control unit. The activities calculated by the operators are memorized in associated memory spaces that are addressable by an activity address. To facilitate reconfiguring the network, the memory space of at least one portion of the operators contains the activity addresses of other operators of the network. Hence, the input activities of these operators may be issued from any other operators in a way that is modifiable by simply changing the values of the activity addresses. The invention is particularly suited to image and sound analysis and synthesis.
