  • Patent number: 7603781
    Abstract: Foliage trimmer with adjustable curvature of the flexible cutting blade assembly for the purpose of cutting convex shapes comprising of a trimmer body with pivotally mounted handle mechanism attached to a flexible curvature adjuster band with a uniform curvature maintainer mechanism attached to trimmer body to maintain equidistant spacing between the bolt axis and to prevent the formation of a ununiform curvature. The curvature of the flexible cutting blade assembly is adjusted with the release of the restraining mechanism with the fingers of the hand that also adjusts the pivotal movement of the front handle mechanism. The flexible cutting blades of the flexible cutting blade assembly are linearly reciprocated via resilient flexible cams of the drive mechanism connected to the motor means located in trimmer body.

  • Patent number: 7574802
    Abstract: The present invention discloses a shaving aid dispensing device for use with a razor cartridge that includes an inner wall and an outer wall that defines at least one reservoir. The inner wall of the dispensing device further defines an aperture sized for passing a shaving cartridge therethrough. A storage medium is disposed in, and substantially fills, the reservoir(s). A shaving aid material is distributed in the shaving aid storage material. A wick substantially covers the reservoir and is operable to draw the shaving aid from the shaving aid storage material by capillary action. The present invention, therefore, provides a user with a shaving aid dispensing device adjacent to a razor cartridge that readily provides a shaving aid material while the user is shaving.

  • Patent number: 7455002
    Abstract: A method and apparatus is provided for cutting an elastomeric laminate that may include a layer of reinforcement cords, into a desired length without cutting through the cords. The method includes the step of cutting through the gum portion of the elastomeric composite material at a desired skive angle, and then opening up the skived cut. Next, the cord reinforcement layer is cut without severing the reinforcement cords. An elastomeric composite strip cut to the desired length is produced and has cut ends. One of the cut ends has the gum portion cut at a desired skive angle adjacent an overhang portion of the reinforcement layer. The opposite end of the elastomeric composite segment also has a skived portion to mate with the skived portion of the first cut end, and a gap in the cord ply to mate with the cord overhang of the first end, resulting in a splice. An improved anvil having independently controlled vacuum zones is also provided, as well as improved cutting mechanisms.

  • Patent number: 7426787
    Abstract: Provided is an apparatus for lifting a retractable lower safety-guard on a circular saw. In one representative implementation, an actuator is attached to the circular saw and an elongated arm is coupled to the actuator such that operating the actuator causes the elongated arm to lift. In addition, an engagement element is attached to the retractable lower safety-guard of the circular saw. When lifted, the elongated arm engages the engagement element, thereby retracting the retractable lower safety-guard of the circular saw. Preferably, the actuator is configured, and is located sufficiently close to a power switch for the circular saw, so that the actuator can be operated simultaneously with the power switch using a single hand. Also provided are retrofitting techniques for attaching such a device to an existing circular saw.
