  • Publication number: 20130165021
    Abstract: An electrically powered knife sharpener for ceramic (or other brittle, crystalline or amorphous media which could be used for blades) knives includes at least one pre-sharpening stage with a sharpening member(s) and includes a final stage with a sharpening member(s). There are one or more motor driven shafts on which the abrasive surfaced sharpening members, such as disks, are mounted. Guide structure is provided to guide the knife for aligning and positioning the knife facet precisely at a defined location on the abrasive surface of each rotating sharpening member. The pre-sharpening stage sharpening member(s) moves in a first direction. The final stage sharpening member(s) moves in a second direction which differs from the first direction.

  • Patent number: 8430720
    Abstract: A knife edge enhancing apparatus includes a support having a support surface and knife blade clamping structure mounted to the support and located above the support surface. An object having a knife edge modifying surface which could be abrasive or non-abrasive is mounted to a holder which is freely slidable on the support surface so that the object surface can be manually moved into contact with a knife edge facet. At least one of the clamping structure and the object surface is angularly adjustable to control the angle of contact of the object surface with the knife edge facet.

  • Patent number: 8124917
    Abstract: A vessel for preparing heated water or other liquid includes a container, an electric heater and a temperature sensing probe mounted through a wall of the container. The probe includes an efficient heat transferring structure in direct thermal contact with and wet by the liquid. An electrical sensor within the probe is in intimate thermal contact with the transferring structure and has electrical properties directly correlating with the temperature of the transferring structure. The transferring structure is attached to a supporting structure mounted to the wall by an elastomeric efficient thermal insulating material held in compression providing physical support for the probe and sealing the wall from leaking and insuring that the sensor is primarily thermally responsive to the temperature of the transferring surface and to the liquid but is thermally insulated from variations in the temperature of the supporting wall.

  • Patent number: 8043143
    Abstract: A sharpener for creating cross-grind knife edges includes a nominally flat annular abrasive sharpening member which could be a ring or a disk and is rotated about its center and held against a moving knife edge facet to simultaneously and sequentially abrade the knife edge at multiple locations on the abrasive member. The disk may be slidably mounted on a shaft in opposition to a spring restraining force. The disk is nominally disposed in a vertical orientation. The sharpener may include multiple stages including a manual stage having a pair of off axis conical shaped rotatable abrasive coated disks which have abrading lines on opposing facets which are not parallel but cross and intersect in a crossing pattern at the blade edge.

  • Patent number: 7745759
    Abstract: An electrically heated water kettle comprises a vessel for holding a liquid for extraction of tea, coffee or other food material. The vessel includes a partially open immersible container sized to allow the passage of water between the walls of the vessel. The container is capable of holding the material while an opening in the container allows the entrance of water into the container upon immersion of the container in the water. The heated kettle incorporates structure to hold the container out of the water until the water reaches an appropriate extraction temperature and to immerse or withdraw the container into or from the water as is necessary to accomplish the extraction.

  • Patent number: 7686676
    Abstract: A knife sharpener is provided which is capable of precision sharpening of hunting and similar knives that have a first and second blade face, each of which terminates at a facet that meets the corresponding facet to create the knife edge. At least the first of the blade faces has a lower distinct planar or concave section adjacent the edge facet with the lower planar or concave section of the face being set at an angle to the center line of the blade thickness that is different from the angle of the adjoining upper section of the same blade face located adjacent to the back of the blade. The sharpener includes a sharpening member such as one having an abrasive coated surface. The sharpener also includes a planar angle knife guide surface of a knife guide which is designed for intimate sliding and sustaining contact with the second face of the blade in order to position an edge facet on the first of the faces into precise angular relation with the sharpening surface.

  • Patent number: 7685914
    Abstract: A food slicer comprises a fan-cooled electrically powered motor driving a slicer blade. The motor is mounted within an enclosure which comprises at least one air intake port and at least one exhaust port on opposite sides of one nominally air-tight first partitioning wall within the enclosure to confine the flow of cooling air from the air intake port through the enclosure, then into intimate contact with the electrical windings and components within the frame of the motor. The motor frame is sealed into a closely conforming contacting aperture in the first partitioning wall. The fan is mounted immediately adjacent to a non-contacting aperture in a second partitioning wall within the enclosure juxtaposed the exhaust port.

  • Patent number: RE43884
    Abstract: An apparatus for manually steeling or conditioning the edge of a knife blade comprises a precision angle guide attached to a manual sharpening steel. The angle guide establishes a guiding surface that provides for sustained sliding or rolling contact with the face of the knife blade such that the plane of at least one edge facet adjacent to the edge of the blade is maintained at a precisely established angle relative to the plane of the sharpening steel surface at the contact point of the facet with the surface of the sharpening steel.
