Title: Circuit interrupter with arcing fault protection and ptc (positive temperature coefficient resistivity) elements for short circuit and overload protection
Inventor: SCOTT GARY W
IPC: H02H9/02
Filed: 1999-08-03
Abstract: A circuit protection apparatus employs a PTC element for overload and/or short circuit protection and an arcing fault interruption arrangement. The circuit protection apparatus may be employed in a ground fault receptacle for interrupting the flow of electrical current in a line in response to any of a plurality of different types of fault conditions on the line. The circuit protection apparatus may include a set of contacts connected in series with the line, and having an open position and a closed position, a trip device coupled to the contacts, adapted to be actuated by a trip signal, to move the contacts from the closed position to the open position and an element having a positive temperature coefficient of resistivity (PTC) connected in series with the contacts. The PTC element is connected to the trip device to provide the trip signal to the device in response to overload or short circuit conditions in the line. A switching element is operatively coupled with the trip device for providing the trip signal to said device in response to an actuating signal. An arcing fault circuit is adapted for detecting an arcing fault in the line and producing the actuating signal when the arcing fault is detected.

Title: Ground working implement including a shank and a tip
Inventor: HALFORD CHRISTOPHER J
IPC: A01B15/02
Filed: 1998-02-27
Abstract: A shank and replaceable tip of a ground working implement are defined from flat plate which is cut by laser or similar or is stamped to provide interconnecting elements between the replaceable tip and the lower end of the shank. At the lower end of the shank is provided a pocket defined by a recess cut into the lower end and a pair of plates welded on respective sides of the flat plate so that the projection of the replaceable tip extends into the pocket to hold the tip in place. This allows a rugged construction of the tip and various designs of tip can be manufactured simply by reprogramming the cutting process. A guide surface is mounted on the front plate of the shank with that guide surface defining a channel member with a leading edge increasing in radius of curvature from the lower end of the shank upwardly to a top of the guide surface spaced upwardly from the ground.      This increase in width of the guide surface assists in discarding trash.

Title: Methods and apparatus for ablating tissue
Inventor: HARTMAN RAYMOND A
IPC: A61B18/22
Filed: 1998-10-02
Abstract: A tissue drill for reduced-trauma tissue ablation includes an optical fiber and a handpiece. The optical fiber has an inlet for receiving laser energy from a laser energy source and an outlet for emitting laser energy. The handpiece is adapted to receive the optical fiber in a controlled and movable relationship. In use, a distal end of the handpiece is placed against tissue to be ablated. The optical fiber is advanced beyond the distal end of the handpiece and into the tissue while emitting laser energy. The emitted laser energy ablates the tissue as the optical fiber advances. The optical fiber may then be retracted from the tissue, thereby resulting in a channel formed in the tissue. The optical fiber may also rotate while advancing into the tissue.  In this regard, the outlet may be offset from a rotational axis of the optical fiber to reduce the level of laser energy transferred to surrounding tissue, thereby reducing trauma to the tissue. The tissue drill is particularly suited for performing transmyocardial revascularization (TMR) and similar procedures.

Abstract: A fuel cells stack of the present invention includes a plurality of unit cells, which are laid one upon another. Each unit cell has a hydrogen electrode and an oxygen electrode, which are disposed across an electrolyte membrane. The electrolyte membrane is a hydrogen ion exchange membrane, which is mainly composed of a sulfonic acid group-containing perfluorocarbon polymer. The electrolyte membrane is designed to have a varying concentration of sulfonic acid group in such manner that the concentration of sulfonic acid group in a contact area, where the electrolyte membrane is in contact with the hydrogen electrode, is approximately one tenth of the concentration of sulfonic acid group in a residual area. The electromotive force of the unit cell varies according to a difference in hydrogen ion concentration between the hydrogen electrode and the oxygen electrode. The varying concentration of sulfonic acid group enables the hydrogen ion concentration in the contact area, where the electrolyte membrane is in contact with the hydrogen electrode, to be lower than the hydrogen ion concentration in an opposite contact area, where the electrolyte membrane is in contact with the oxygen electrode, on an occasion of power generation. This arrangement desirably enhances the electromotive force per unit cell.

Title: Modulating retroreflective article
Inventor: FLEMING MADELEINE B
IPC: G02B5/18
Filed: 1998-06-03
Abstract: Retroreflective articles provide modulating retroreflection using a front surface (120) that includes at least first and second areas (122, 124) having different transmission characteristics and a back surface (130) that includes retroreflective areas (132) and separation areas. The first and second areas (134) on the front surface are arranged relative to the retroreflective areas and the separation areas on the back surface such that a substantial portion of light incident on the first areas of the front surface at a first angle is transmitted through the first areas of the front surface to the retroreflective areas on the back surface where it is retroreflected back through the front surface. In addition, a substantial portion of light incident on the first areas of the front surface at a second angle is transmitted through the first areas on the front surface to the separation areas. Together, the front and back surfaces manipulate light such that the retroreflective articles provide modulating retroreflection of incident light where the modulation or variation can be between, e.g., retroreflection or no retroreflection, retroreflection of different colors, retroreflection at different brightness levels, etc. In other words, when subjected to incident light from a steady light source, relative movement between the retroreflective article and the light source can result in variations or modulation in the retroreflection of light from the light source. When retroreflective articles provide modulating retroreflection, the variations or changes will tend to increase the conspicuity of an object or person on which the retroreflective article is located.
