  • Publication number: 20250289070
    Abstract: An indexable piercing tip mounts to a nose portion of one of the jaws of a heavy-duty demolition shears so as to enclose and protect top, bottom, front, and two opposing side surfaces of the nose portion during use of the shears. The piercing tip has a first operative position in which a first set of piercing and shearing edges of the piercing tip are presented for use. When the first set gets dull or worn, the piercing tip can be rotated/indexed 180° degrees so as to present a second set of piercing and shearing edges of the piercing tip for use.

  • Publication number: 20250123444
    Abstract: An integrated MEMS waveguide modulator, including: a static, non-suspended waveguide to guide light traveling through the waveguide; and a dielectric slab movable into and out of an evanescent field surrounding the waveguide using an actuation mechanism, wherein the dielectric slab is movable between a first position that is farthest away possible for the slab from the waveguide and a second position that is closest possible for the slab from the waveguide, wherein dispersion characteristic of the light is controlled by moving the dielectric slab from an unactuated mode that is at the first position to an actuated mode that is at the second position, and wherein the dielectric slab is layered to include non-uniform refractive index profile.

  • Patent number: 10967380
    Abstract: Heavy-duty material processors (e.g., shears, concrete crushers) include a jaw that pivotally connects to another jaw. A hydraulic cylinder extends between the jaws to open and close the jaws in a shearing motion. Cutting/shearing/crushing blade inserts mount to detachable blade holders, which in turn mount to one of the jaws. Wedge blocks securely and detachably attach the blade inserts to the remainder of their associated jaw, and rely on force-amplifying wedge surfaces to ensure a secure attachment. The detachable blade holders may include lateral flanges that extend across an otherwise exposed face of their respective underlying jaw bodies to protect the jaw bodies during use. A blade on one of the jaws is laterally adjustable, which helps to free a jam if one of the jaws gets jammed into the space between blades in the other jaw.

  • Publication number: 20170100985
    Abstract: A refrigeration efficiency monitoring system detects degradation of a refrigeration system by monitoring a deviation from a normal operating status of the refrigeration system at an early stage of such degradation. The monitoring system detects and calculates a plurality of system parameters associated with the refrigeration system. The monitoring system then determines a decrease in efficiency of the refrigeration system based on comparison between the system parameters and reference values representative of the normal operating status, and generate a service recommendation based on the determination.
