Abstract: An edge sharpener, in particular for sharpening the steel edges of skis, is composed of a main body in which there is a recess for holding a file blade and within which is inserted a clamping wedge so as to exert distributed forces on the surface area of the file blade when the clamping wedge is forced into the recess substantially radially. In a particular feature of the invention, the main holder has a flexible foil which comes to lie between the pressure surface of the clamping wedge and the surface of the file so that movement of the clamping wedge does not result in abrasive contact with the surface of the file. The lower part of the clamping wedge has an inclined surface which cooperates with a similarly inclined surface in the holder. The clamping wedge is further equipped with gripping surfaces so that, during manual use, the force of the hand on the sharpener to execute the sharpening strokes tends to move the clamping wedge more forcefully into the recess, thereby increasing the clamping action.

Abstract: An apparatus for signaling if a fish bites a fishing line. The apparatus includes a housing containing a contact bar and an arm. The contact bar and arm are connected to a battery powered electrical circuit that sounds an alarm and energizes a lamp if they contact each other. The arm is biased into contact with the contact bar in the normal state. A cord is secured between the end of the arm and the fishing rod. The fishing rod is positioned by a rod holder so that it maintains enough tension in the cord to draw the arm out of contact with the contact bar. Should a fish bite, the end of the rod will dip, releasing enough tension for the arm to contact the contact bar to cause a signal which may be both visual and audible.

Abstract: An apparatus for edging the periphery of an ophthalmic lens to a predetermined outline or edge configuration, is characterized by a work holder for supporting and rotating a lens while moving an edge of the lens against a grinding surface of a grinding wheel. During grinding the lens is engaged with only a portion of the surface, and to prevent a groove from being formed in the surface a sensor automatically detects the highest point on the surface and controls movement of the work holder to move the lens thereagainst. In consequence, the wheel wears evenly, it retains a substantially cylindrical shape, all portions of its grinding surface are effectively used in grinding lenses, and formation of a groove in its surface is prevented, whereby the wheel does not require retruing or reshaping and its useful life is significantly increased.
