  • Patent number: 10270233
    Abstract: A manually-operated wire stripper is a device for cutting and removing the electrical insulation from an electrical wire. The device includes a base plate onto which a first mounting plate and a second mounting plate are perpendicularly mounted. A first rod is rotatably mounted through the first mounting plate and the second mounting plate. A cutting assembly is mounted for longitudinal movement to the first rod and may be moved into position such that a blade of the cutting assembly is aligned with a selected slot from a plurality of wire slots traversing through the base plate. An electrical wire may be stripped by inserting the electrical wire through the selected slot, creating a cut in the electrical insulation with the blade, and then manually pulling the electrical wire through the selected slot to remove the electrical insulation along the length of the electrical wire.

  • Patent number: 10092994
    Abstract: The housing of a grinding spindle unit is pivotably mounted by way of a pivot axle on the receiving part of a grinding machine, e.g., on a grinding headstock. The grinding spindle unit bears a grinding wheel which is driven in rotation. The actuation of an adjusting unit extends a pressure pin, which pivots the housing of the grinding spindle unit about the pivot axle and thus slants the grinding wheel. The pivot axle is in this case formed as a film hinge through a zone of targeted elastic material deformation. A tensile spring device brings about constant contact between the pressure pin and the receiving part.

  • Patent number: 10081116
    Abstract: A saw has a system for sensing the torque on a cutting blade to signal when the blade begins to cut material. The saw has a drive belt extending between a driven wheel and a drive wheel and a belt tensioner that engages a side of the belt and maintains tension in the belt. The belt tensioner is movable to maintain the tension in the belt. A control system calculates the movement of the belt tensioner. The saw has a system for determining the size of the sacrificial blade. A through beam photoelectric emitter and receiver pair are positioned on opposite sides of the blade such that a largest cutting blade is moved above the beam regardless of a horizontal position of the cutting blade and sensor senses a vertical position of the axis of the blade. The sensor senses the vertical position of the blade axis when the blade is moved above the beam.
