Publication number: 20030126930Abstract: The present invention provides a simple design for a temperature-insensitive extrinsic polarimetric strain sensor. The sensing element is a thin sheet of photoelastic material that is bonded to the test object. It is illuminated with linearly polarized light with the polarization direction at 45 degrees relative to the strain-induced fast and slow axes in the photoelastic material. The sensor measures the difference between the strains along these two orthogonal directions. The reduced sensitivity of the sensor to temperature results from the fact that the illumination is perpendicular to the surface of the test object. All polarization components that are parallel to the surface will experience identical refractive index changes due to thermal effects. Consequently, a measurement of the difference in strains along two directions in the surface plane is insensitive to temperature.Type: ApplicationFiled: November 26, 2002Publication date: July 10, 2003Inventors: Gonzalo De La Puente, Paul E.

Publication number: 20030126955Abstract: A wire stripper has a pair of elongated frames pivotably joined together by a pivot pin and defining handles and jaws. The handles are covered by sleeves which include thumb wells which cover the ends of the pivot pin. A mechanical interlock is provided between the handles and the sleeves. The sleeves have slots for receiving the handles. The slots are offset so the front and rear surfaces of opposite sleeves are coplanar. The sleeves have a core and cushion grip overmolded on the core. A molding projection on the core allows precise placement of the core in a mold during formation of the cushion grip. A spring biases the frames to an open position. A locking member can be set by a sliding motion toward the handle end to hold the handles in a closed position. A curved shoulder on the edge of a handle wipes across a screw hole opening in the opposite jaw to provide a screw cutting function with a slicing action.Type: ApplicationFiled: January 8, 2002Publication date: July 10, 2003Inventors: Bruce W.

Publication number: 20030126957Abstract: A socket wrench includes a spanner and a joint. The spanner includes an elongated body, an annular head, a driving element received in the annular head and a ratchet mechanism arranged between the annular head and the driving element. Thus, a one-way rotation of the driving element can be selectively provided while the spanner is swayed. The driving element defines a hole. The joint includes a middle section, a first terminal section and a second terminal section including a size different from that of the first terminal section. The middle section is used for insertion in the hole, the first terminal section is used for engagement with a socket of a first series while the second terminal section being used for engagement with a socket of a second series.Type: ApplicationFiled: February 11, 2002Publication date: July 10, 2003Inventor: Hsiu-Ching Huang

Publication number: 20030126959Abstract: A strap wrench comprising a handle with a central channel and detachable strap anchored at one end of the handle. The strap is held in place in a channel by means of a rocker arm which is biased to press the strap against a portion the strap positioned in the channel. The strap is initially positioned in the channel by the user pressing one side of the rocker arm to open the channel. Once the strap is initially seated, the rocker arm may be released and the loop may be further tightened by pulling the strap through the channel. Free movement of the strap may be enhanced by applying pressure to the rocker arm.Type: ApplicationFiled: February 13, 2003Publication date: July 10, 2003Inventor: Anand V. Khubani

Publication number: 20030126963Abstract: The invention is directed to a die cutter monitoring system. In an exemplary embodiment the system includes a frame that supports a die. A counter plate is located opposite and aligned with the die. A substrate is placed between the counter plate and die. The counter plate forces the substrate into contact with the die. A force measuring device measures the force of the cutting stroke. The force measuring device generates an output signal. The output signal is analyzed relative to acceptable conditions and operating parameters. If the die cutter is operating outside of acceptable limits, an adjustment signal is generated and sent to the die cutter control system or operator.Type: ApplicationFiled: February 20, 2003Publication date: July 10, 2003Inventors: Denny E.

Publication number: 20030126964Abstract: Method for the rapid cleaning of produce with minimal loss, and apparatus to perform the method. The cleaning method taught in the present application enables the rapid cleaning of produce by removing an extraneous portion therefrom, by separating the extraneous portion from the body of the produce, and by urging the cleaned produce towards a collection device. These steps are attainable, using the principles of the present invention, by a working using only one motion and one hand. To perform the method, a novel aperture knife is taught which, rendered attachable to an agricultural processing implement by an integral attachment device, enables one-handed operation by a user. The knife includes a generally planar knife body in operative combination with an elevated blade which not only enables the severing of the extraneous portion from the produce body, but separates the extraneous portion therefrom, and guides the cleaned produce body towards a collection device, for instance a picking box.Type: ApplicationFiled: February 26, 2003Publication date: July 10, 2003Inventors: Edward Ortega, Carlos Ortega
