Abstract: A cartridge retention tool may be used for restraining a spent cartridge during primer pocket cleaning. The tool may have jaws that may be sized to approximately fit the cartridge and secure it from moving during the cleaning process. The tool may employ mechanical leverage to reduce the amount of force required to restrain the cartridge within the jaws.

Abstract: A dust-collector locking/unlocking device to lock or unlock a dust-collector removably mounted in a cleaner body. The dust-collector locking/unlocking the device includes a first member and a second member connected with a lower portion of the first member and serving as a cover for the dust-collector. The first member includes a first hook that is rotatably connected with an upper wall of the cleaner body, a manipulation lever that protrudes from an outer circumference of the first member for rotation of the first member by a user, and first cam parts formed on a lower portion of the first member. The second member includes a second hook movably connected with guide cams formed on the first member, and second cam parts engaged with the first camp part. The second member is moved up and down by the rotational movement of the manipulation lever and thereby lock or unlock the dust-collector.

Abstract: A cyclonic separation device for a vacuum cleaner including a cylindrical separation container, an inlet tube parallel to the axis of the chamber having a vortex vane disposed axially in the inlet tube. Air rotates in one direction in the inlet tube, and preferably in the opposite direction in the separation chamber tube. The separation chamber includes a cylindrical sidewall with an upper central outlet tube and a closed bottom for collecting separated dirt. A disrupter ring located on the inside wall of the middle portion of the separation chamber includes a curved surface and sharp edge for lifting air flow off the chamber wall. A outlet tube disc spaced from the inlet of the outlet tube is located in the chamber below the disrupter ring.

Abstract: The present invention is regarding to a structural improvement of a clamp which includes a flex attached to a handle set, an actuator cable extends through the slider and is linked to gripper device, of which the openings and open notch are built in, it offers a convenient scheme for operator to detach or engage actuator cable from gripper device, by simple operation, gripper devices may be conveniently interchanged in order to meet versatile needs in various situations.

Abstract: Apparatus for fixing identification tags on animals, composed of two symmetric parallel sections, each of which has, in its central part, a gap, both sections being connected to each other by means of rectangular metal strips that have the same form, overlapping and crosswise to each other, these being connected by a pin which carries a spring the ends of which are fixed to pins which connect the metal strip to the corresponding section of the apparatus in a rotatable manner, mentioned metal strips having, at their opposite ends, "L"-shaped gaps which have pins perpendicular to the sides of the corresponding section, that go through mentioned sides, and are fixed to the sides in such a manner as to, when the two sections close upon closing the handle ends of the apparatus, the tag is closed, at which instant the corresponding pins reach the juncture of the two sides of the "L"-shaped gap, the pin afterwards proceeding up the shorter leg of the "L"-shaped gap as pressure is maintained on the handles, resulting

Abstract: A finger wrench or the like for threading and unthreading articles such as nuts or bolts has a pair of slidingly interfitted jaw members with respective finger openings and article gripping edges between the finger openings. In use, the gripping edges are opened out and fitted over an article to be manipulated so as to engage opposite surfaces of the article. Torque is applied through the finger openings. Increased leverage may thus be applied to the article compared with gripping it directly in the fingers, the increase in lever arm being represented by the distance from the respective gripping edges to the finger openings.

Abstract: A tool for crimping electrical terminals (10) to terminate conductive wires (20) by inelastic deformation of portions of the terminal includes a motor driven cam (42) connected to toggle linkage (48) adapted to drive a double acting linkage (30,32) to effect die displacement against the terminal through a disk (78) mounted for rotary movement in a race (80), the double acting linkage providing an enhanced mechanical advantage in the high force requirement zone of die displacement.

Abstract: A crimping tool of the type employed in crimping or compressing an article such as an electrical connector which has a substantially fixed jaw which has a surface against which an article is compressed, a ram having a surface for supporting a die and an article, the ram being mounted for movement toward and away from the jaw, and a die holder which is pivotally mounted to the ram to keep the compressing surface of the jaw and the supporting surface of the ram parallel throughout the movement of the ram in the event that the jaw deflects slightly during operation of the tool.
