Patent number: 7703487Abstract: A cutterhead for use with a power tool includes a generally cylindrical body with a knife recess extending generally parallel to an axis of the body. The knife recess has a wall at an acute angle to a tangent of the outer surface. Received in the knife recess are a knife and a bar that includes an angled side configured to sandwich the knife between the angled wall of the recess and the angled side of the bar. A pin extends from the bar and is received in an aperture of the knife to align the knife relative to the bar. A threaded height adjustment screw is received in a threaded bore in the bar to adjust a height of the knife with respect to the body. A securing screw is received in a threaded opening in the body to secure the bar and the knife to the body.Type: GrantFiled: September 18, 2006Date of Patent: April 27, 2010Assignee: Black & Decker Inc.Inventors: Jaime Garcia, Jeffrey Weston

Patent number: 7703366Abstract: A gear and shaft assembly that translates the bevel of a power tool to an indicator more easily readable by an operator provides a front bevel indicator and locking mechanism. A locking mechanism is conveniently placed within reach of the operator and directly controls the motion of the gear assembly. The front bevel indicator may provide a higher resolution of the tilt angle by selection of the various gear ratios of the gears that translate the bevel position of the power tool mounted in the rear to the front of the mount of the power tool.Type: GrantFiled: November 14, 2007Date of Patent: April 27, 2010Assignee: Black & Decker Inc.Inventors: Jaime Garcia, Vance Roe

Patent number: 7433562Abstract: The invention relates to a method of dividing the power of an input electromagnetic signal into two equal-power signals with a relative phase difference of 180° between them and an equal propagation delay. The inventive method makes use of a photonic crystal coupler comprising two parallel guides which are disposed close to one another and which are based on coupled cavities. The method consists in exciting the odd mode of the coupler which, owing to the symmetry thereof, ensures that the field maxima coincide in one guide with the minima in the adjacent guide, thereby producing a relative phase difference of 180°. The two output signals are obtained through the spatial separation of the guides forming the coupler, making use of the property possessed by guides in photonic crystals for high transmission efficiency through very tight curves. In this way, the size of the structure can be reduced considerably. The inventive method can be used for both two-dimensional and three-dimensional photonic crystals.Type: GrantFiled: August 14, 2004Date of Patent: October 7, 2008Assignee: Universidad Politecnica de ValenciaInventors: Javier Marti Sendra, Alejandro Martinez Abiétar, Pablo Sanchis Kilders, Francisco Cuesta Soto, Jaime García Rupérez
