Abstract: A hand-held machine tool, particularly an angle grinder, has a device housing (10) which is divided into a motor housing (11) and a handle (15) which is arranged at one end of the latter and is rotatable relative thereto. A positioning device (20) ensures that the rotatable handle (15) is fixed in different rotational positions at the motor housing (11). A simple construction of the positioning device (20) is achieved in that a central bearing neck (22) is formed on at the motor housing (11), one of the housing shells (151) of the handle (15) which is constructed from two shells being supported in an annular groove (23) provided at the bearing neck (22).

The inventive opener simplifies the tasks of opening tab-top beverage containers end certain vehicle door handle systems, while protecting a user's hands and fingernails.

Abstract: Apparatus for severing and stripping a portion of a coating material from an elongated member such as an insulated electrical conductor, or the like, utilizing a pair of overlapping blades having cutting edges formed at the junction of two planar surfaces meeting at an acute angle. The blades are moved relative to one another, radially of the conductor, to cause the cutting edges to move radially partially through the layer of insulation. Relative movement of the blades and conductor axially of the conductor completes the severing of a slug of insulation, all in accordance with the prior art. The present apparatus is distinguished by making the planar surface portions immediately adjacent the cutting edges of the overlapping blades and engaged with the portion of the insulation to be stripped, i.e., the portions of the blades which apply the axial severing force, at equal angles, either 90.degree. or an acute angle, to the direction of relative movement.

Abstract: Tools and dies are made from a master pattern by making a hard chromium electroformed shell from the pattern, supporting the pattern and filling it with tool steel which applied by spray deposition of molten particles, the deposit being continuously densified by peening as it is made.

Abstract: The oscillating grinder includes a housing; a drive motor having a rotatably driven armature shaft and mounted in the housing; a grinder plate connected with the housing by one or more supporting members each having a long side; an eccentric element mounted eccentrically on the armature shaft for converting a rotary motion of the motor into a linear motion of the grinder plate; and a transmission element having a long side and connecting the eccentric element to the grinder plate. The transmission element and the supporting members have different angular moments of inertia in different directions so that a displacement of the eccentric element in one direction, advantageously in the handle direction, is completely transmitted to the grinder plate, but a displacement in another direction transverse to the first direction is no more than incompletely, and preferably not at all, transmitted to the grinder plate, thus providing a linear grinding motion.

Abstract: A sand belt device can be mounted detachably on a body portion of a portable grinding machine so as to replace a grinding wheel of the portable grinding machine. The sand belt device includes a positioning member which has a front part and a rear part that is fitted tightly and detachably around an annular flange of the body portion. The rear part has a hole through which a rotatable shaft of the body portion passes. A roller unit includes a driven roller and a driving roller which is mounted detachably on the rotatable shaft of the body portion and which is rotatable with the rotatable shaft. An elongated belt frame has a front end and a rear end that is attached stationarily and detachably to the front part of the positioning member. A supporting unit, which is mounted movably to the elongated belt frame, is used to support the driven roller so as to position the driven roller in front of the elongated belt frame. An endless sand belt passes over the roller unit and the elongated belt frame.

Abstract: A wire stripper (10) for stripping an outer insulative jacket from a cable (12) includes a frame (14) which carries a cable clamp (16) for releasably clamping the cable. The frame also carries a slitting mechanism (43) which includes a rotatable blade carrier (46) and a central passage (48) through which the cable passes. The blade carrier includes a pair of blades (60--60) each radially movable within a separate one of a pair of diametrically opposed slots (56--56) so as to circumferentially slit the insulative jacket when the blade carrier is rotated in a first direction. A gripping mechanism (94) is slidably mounted to a pair of rails (100--100) carried by the frame for gripping a portion of the cable downstream of the blade carrier so as to pull the severed portion of the outer insulative jacket from the cable when the gripping mechanism is displaced by a lever (108).

Abstract: A saw blade sharpening apparatus for sharpening an elongated blade having a plurality of aligned cutting teeth. The apparatus includes a grinder mechanism to sharpen the teeth. The grinder includes a body and a rotating grindstone, the grindstone having an axis aligned with the blade. The rotating grindstone continuously circulates in a rotational pattern to move the grindstone across the surface of one of the teeth to grind the entire surface of the tooth. At the same time, the rotating grindstone advances the blade linearly from the tooth being ground to the next tooth in succession.

Abstract: A sharpening tool for pointed objects is described. The device is comprised of a cylindrical body with a hole extending part way through it from one end.
