  • Patent number: 10148138
    Abstract: A motor includes a rotor having a plurality of pole magnets angularly spaced about the rotor's rotational axis through an angle of 360°, and a stator including a plurality of windings angularly spaced about the rotational axis through an angle less than 360° to provide an angular section free of windings, wherein at least one of the plurality of pole magnets is not radially opposite any of the plurality of windings at any given rotational position of the rotor. The motor is designed for use in powering a horizontal blade reel of a cylindrical lawn mower, and includes a housing having a cross-sectional shape in the form of a chord-truncated circle, such that the housing has a flat portion corresponding to the angular section free of windings. The truncated motor housing avoids unattractive “layover” of grass during mowing.

    Abstract: A phacoemsulsification needle for use with an ultrasonic handpiece in performing cataract surgery has a plurality of external grooves along its shaft. The external grooves are configured to convert longitudinal drive motion delivered by the handpiece at the base of the needle into torsional motion at the needle tip. The torsional motion at the needle tip has a magnitude greater than the magnitude of the longitudinal drive motion at the base, i.e. the longitudinal to torsional gain is greater than one. The grooves may be helical grooves, wherein the groove configuration is defined by a set of groove parameters including a helical pitch of the grooves, a width of the grooves, a depth of the grooves, an axial length of the grooves, and a total number of grooves.

  • Patent number: 10138926
    Abstract: A low-cost, lightweight telescoping torque tube assembly is reliable, safe, and easy to operate. The assembly has no loose fasteners, and no tools are required to operate the telescoping assembly. The telescoping torque tube assembly has only two parts, namely an end fitting and a torque tube. A resiliently deflectable locking tab is provided on one of the parts, and the locking tab is received by a corresponding locking slot formed in the other part. The locking tab has an abutment edge, and the locking slot has a limit edge facing the abutment edge for engaging the abutment edge when the locking tab is undeflected to prevent axially directed adjustment of the end fitting relative to the torque tube from an extended position toward a retracted position. A user deflects the locking tab to enable adjustment of the end fitting from the extended position to the retracted position.

  • Patent number: 10066715
    Abstract: An electromechanical actuator (“EMA”) is provided with redundant load paths for driving the actuator stroke. The EMA includes a rotatable screw, a nut mated with the screw and having an external toothed surface, and a rotatable spline member having a splined surface engaging the external toothed surface of the nut. An actuator rod is coupled to the nut for linear movement with the nut. A first motor is operable to rotate the screw relative to the nut to cause the nut to travel linearly along the screw, and a second motor is operable to rotate the spline member and nut such that the nut travels linearly along the screw. Consequently, the actuator rod moves linearly by operation of the first motor alone, by operation of the second motor alone, and by simultaneous operation of the first and second motors. A no-back device may be incorporated into each load path.
