  • Patent number: 11788251
    Abstract: An adapter board defines an upper adapter board attachment portion, and a lower tool bit attachment portion. The upper adapter board attachment portion includes a first peak surface and a second peak surface, the first peak surface and the second peak surface forming a first valley between the first peak surface and the second peak surface.

  • Publication number: 20220195550
    Abstract: An example track shoe, cutting edge, or other component of a machine is formed in a heated process, such as hot-rolling followed by air-hardening. The air-hardening process involves cooling the component by flowing air over the component (e.g., air cooling), such that the component is cooled at a controlled rate. During the air-cooling process, such as in the range of about 250° C. to about 1100° C., the component may be machined, such as by shearing, punching, drilling, etc. The machining may form the final shape of the component. As the air-hardening process is completed, and the component approaches room temperature, the component may have at least 5% bainitic crystal composition, and as high as greater than 80% bainitic crystal composition, resulting in relatively high hardness and fracture toughness. The final track shoe may have a hardness between about 40 HRC and 55 HRC.

  • Patent number: 10889959
    Abstract: A blade assembly comprises a moldboard defining an upper moldboard free end and a lower moldboard free end, the lower moldboard free end defining a lower curved mounting surface, and an adapter board defining an upper adapter board attachment portion, and a lower tool bit attachment portion. The upper adapter board attachment portion may include a first peak surface and a second peak surface, the first peak surface and the second peak surface forming a first valley therebetween and being configured to contact the lower curved mounting surface.

  • Patent number: 10187063
    Abstract: Various implementations described herein are directed to a sequential logic device having multiple stages. The sequential logic device may include a first stage having first transistors that are arranged to receive a data input signal and a clock signal and provide a first signal and a second signal based on the data input signal and the clock signal. The sequential logic device may include a second stage having second transistors that are arranged to receive the first signal from the first stage and provide an inverted first signal to a gate of a first pass transistor. The first pass transistor may allow the second signal to pass from the first stage to a second pass transistor based on the inverted first signal, and the second pass transistor may allow the second signal to pass from the first pass transistor to ground based on the clock signal.

  • Patent number: 9809959
    Abstract: A retention system is provided for use in connecting a replaceable tool to a work implement. The retention system may have a generally cylindrical pin with a first hollow end, and a second hollow end located opposite the first hollow end. The retention system may also have a first fastener configured to engage the first hollow end and cause the first hollow end to flare radially outward. The retention system may further have a second fastener configured to engage the second hollow end and cause the second hollow end to flare radially outward.
