  • Patent number: 4386541
    Abstract: A pair of interlocking single filament or multifilament loops (6,7) are mounted on the opposed operating ends (4,5) of a pliers action type hand tool. An aperture is formed between the two loops through which an optical fibre (31) complete with soft plastics primary coating (32) is inserted. The loops are tensioned by operation of the tool, and while this tension is maintained the fibre is removed causing the coating to be stripped off by the tightened loops.

  • Patent number: 4384431
    Abstract: A conical end portion of a connector plug and an end portion of a lightguide fiber which is encapsulated by the plug are prepared to form a conical end portion which is suitable for interconnection with a conical end portion of another plug within a sleeve with precise end separation of opposing end portions of the fibers. The conical portion of the plug is seated in engagement with a surface which is mateable with the outwardly facing surface of a conical end portion of the plug with an end portion of the fiber extending beyond the plug. In order to prepare the lightguide fiber, a disc which is mounted for rotation about an axis that is parallel to the longitudinal axis of the end portion of the lightguide fiber is moved along a path of travel obliquely transverse of the lightguide fiber. This disc is rotated to cause its peripheral edge surface to sever the portion of the lightguide fiber that extends from the plug to form an end surface.

  • Patent number: 4381024
    Abstract: An improved hack saw in which a compression tube together with two parallel adjustable tension rods comprise the main horizontal frame assembly. The compression tube having an inside vertical dimension several times greater than the diameter of the tension rod is held in place by bosses extending from the front side of the handle and the rear side of the blade support arm. One compression rod is located above and parallel to the compression tube. The second rod is positioned inside and at the lower vertical extremity of the compression tube. Tension applied to the rods by means of threaded nuts on the front of the blade support arm applies compression to the compression tube resulting in a frame assembly highly resistant to bending moments and distortion.

  • Patent number: 4378660
    Abstract: A method and apparatus for grinding pairs of gear wheels such as spiral or curved tooth bevel gear wheels whereby a first wheel is ground with a male cup-type grinding tool and a second, counter wheel is ground with a female cup-type grinding wheel with an additional eccentric cyclic motion being applied to one of said wheels. In accordance with a preferred feature of the invention, the grinding tools utilized are not exactly complementarily congruent, the female tool differing by an amount that is equal to the amount of the additional eccentric cyclic motion that is effective in the direction of the tooth normal. The additional eccentric motion is preferably elliptical and in accordance with an apparatus aspect of the invention a drive is provided for achieving such elliptical supplementary motion.

  • Patent number: 4378053
    Abstract: A tool holder has a rotatable drive sleeve adapted to receive therein a tool and having a pair of diametrically opposed slots disposed axially along part of its length. A key extends inwardly into each slot and is movable through its sot for retaining and rotatably driving the tool. The slots have an axial length greater than that of the keys which are slidable axially there along. A locking collar, having an internal surface diverging progressively outwardly over at least a portion of its length in the axial direction, encircles the sleeve and is movable axially in one direction for locking the keys in engagement with the tool, and in the opposite direction to allow disengagement of the tool. The action of the divergent surface portion on the keys enables the keys to be locked in position over a range of inward penetrations to accommodate tools having driving recesses of different depths.

  • Patent number: 4378064
    Abstract: A vibratory feeder employs a three mass system instead of the conventional two mass system to reduce the amount of power to operate the feeder. A base assembly having an armature formed thereon is positioned adjacent an electromagnet. The electromagnet is mounted to the base assembly by a leaf spring system, and a trough assembly is connected to the base assembly by a plurality of leaf springs. The electromagnet forms one mass of the three mass system; the armature and base assembly form a second mass; and the trough assembly forms a third mass. The phase of vibration of the armature relative to the vibration of the electromagnet can be regulated by adjusting the mass of the trough assembly and/or by adjusting the spring rate of the trough springs. The correct choice of mass and of spring rate causes the armature and the electromagnet to vibrate in phase with each other and reduces the mean length of air gap required between the armature and the electromagnet.

  • Patent number: 4376399
    Abstract: Apparatus and a related method for its operation, for removing a cover from a microcircuit package without significant damage to the package or contamination of its contents. The apparatus includes a work table on which the package to be opened is placed, a clamping assembly for removably securing the package to the work table, and a cutter blade positioned in an operative relationship with the clamped package. Also included are adjustment controls to allow for adjustment for the width, length and depth of the cut, and control circuitry for effecting movement of the work table in a cutting stroke with respect to the cutter blade, to cut along an edge of the cover, and for automatically reversing the table movement to return it to its starting position. A vacuum system is employed to remove and contain metal fragments and thereby minimize contamination of the package.

  • Patent number: 4373263
    Abstract: Animal implantates may be removed by a knife that permits the insertion and removal of blades without the manipulation of fasteners. Such a knife may be inexpensively manufactured by molding two relatively simple pieces that can be fitted together to hold a scalpel blade and to permit its incision to be guided and limited in depth. One piece of such a knife forms a handle having a first portion adapted to be gripped by hand and a blade-carrying second portion forming two ribs with a central slot. The second piece is a blade carrier having a first side surface adapted to engage an opening in a blade to hold the blade in fixed position on the blade carrier. The blade carrier has an upper bearing surface adapted to engage a rib of the first handle portion and a surface projecting upwardly centrally of the bearing surface and being adapted to engage the ribs of the first portion.

  • Patent number: 4373565
    Abstract: To provide for effective force transfer upon striking of blows between plastic end portions covering a metal, typically steel, core without damage to the plastic striking end portions (201, 202), the plastic end portions (201, 202) form part of a single unitary plastic element (200) covering the metal core (100) which, generally, is of ellipsoid shape. The metal core has flat end portions (102, 103), with positioning protrusions (104, 105) extending into matching recesses formed in the striking portions (201, 202) of the plastic covering. The various surfaces of the metal core (102, 103; 106; 107, 108; 109) are joined by inclined surfaces which may be flat or curved and form part of the generally ellipsoid surfaces (110, 111, 112) whereby, upon striking of blows, fissures and breakage of the striking portions are avoided.

  • Patent number: 4373286
    Abstract: Fish are captured utilizing a chain reaction of larger fish feeding on smaller fish. A bait-enclosing structure is mounted within a frame, and a first net is provided surrounding and substantially concentric with the bait-enclosing structure. The first net has openings formed therein large enough to allow small fish to insert their heads through the openings in an attempt to feed on the bait and catch their gills on the net if withdrawal is attempted. The assembly is lowered into a body of water, and after a predetermined time period a desired number of fish are trapped within the assembly utilizing a second net surrounding the first net, and then the assembly is raised to the surface. Entrapment may be provided by providing the second net having larger openings than the first net and concentric therewith, so that the fish attempting to feed on fish caught by the first net will be caught by the second net.
