  • Publication number: 20110016726
    Abstract: A specialized wood splitting tool and chopping block, used together, enable cutting kindling from ordinary firewood in an effective and safe manner. The splitting tool uses leverage in addition to downward momentum of the cutting head to split wood. The metal handle and metal cutting head are preferably formed from a single piece of steel, in a perpendicular configuration similar to an adze. A splitting wedge blade within the handle exerts transverse shear forces to enhance splitting, and flat upper surfaces of the cutting head and the handle near the joint provide a striking surface. A complimentary chopping block for bracing logs of various diameters in a steady upright position has a V-shaped recess that is open on one end. The chopping block provides resistance to the unique leverage of the splitting tool during the splitting action.

    Abstract: A method of adhesively bonding an adhesive coated, semi-rigid film to a substrate is reported. The method utilizes at least two alignment tools that are each positioned to substantially contact the surface of a substrate at an outer edge of the substrate. The adhesive-coated, semi-rigid film is then interposed between the first and the second alignment tools and the adhesive is brought into contact with the major surface of the substrate. The semi-rigid film is then aligned by contacting a first side edge of the semi-rigid film with a major surface of a first alignment tool and contacting a second side edge of the semi-rigid film with a major surface of a second alignment tool such that the film is aligned relative to the edge of the substrate. After alignment, pressure is applied to at least a portion of the surface area of the first side of the semi-rigid film to effectuate adhesive bonding of the film to the major surface of the substrate.

    Abstract: An adjustable stop mechanism for limiting the movement of a rip fence toward the cutting plane of a tiltable panel saw as an automatic function of the selected orientation of an abutment bar. The abutment bar has first and second orientations alternately presenting an abutment face of relatively low height, located at a greater distance from a reference surface, and a relatively greater height, located at a relatively shorter distance from the reference surface. When the abutment bar is rotated to the low height orientation, as to accommodate tilting of the panel saw blade, a limit stop position of movement of the abutment bar toward the cutting plane is automatically altered, so that the limit stop for the abutment bar support is farther away from the cutting plane. When the bar is oriented to present a full height abutment face, the limit stop automatically is altered in response to such orientation, to permit the support to move closer to the cutting plane.

  • Patent number: 4617160
    Abstract: A method and related fixtures are disclosed which permit formation of stacks of thin circuitry-carrying layers. The layers terminate in an access plane having a two dimensional array of closely-spaced electrical leads. The method includes the steps of measuring the thickness of separate chips, selecting groups of chips having appropriate thicknesses, applying appropriate amounts of epoxy between adjacent chips, aligning the chips (and their electrical leads) in the direction parallel to their planes (i.e., the X-axis), and closing the cavity with an end wall which (a) exerts pressure on the stacked chips and epoxy in a direction perpendicular to the chip planes, and (b) establishes a fixed height of the stack in order to align the leads in the Y-axis. The final fixture provides a fixed-size cavity for confining the layers during curing of thermo-setting adhesive which has been applied between each adjacent pair of layers.

  • Patent number: 4565358
    Abstract: A plate positioning apparatus which determines the position of a plate workpiece for a processing machine by an aligning member which moves in the X-axis direction and an aligning member which moves in the Y-axis direction. The Y-axis aligning member is provided with a movable retainer which retracts toward the Y-axis side when it comes in contact with the X-axis side aligning member and comprises a base part and an extension member which is remountable on the base part. The aligning member for the X-axis is provided on its upper surface with at least one aligning bar which contacts the plate workpiece. The aligning members for both directions of X and Y axes are adapted to be guided by the base frame and their moving strokes are controlled by position detecting switches provided in the base frame, the base frame being closed at its upper side by the cover plate. The respective slits along which the aligning members move are covered with respective movable dust-proof belts.

  • Patent number: 4433600
    Abstract: A new and unique workpiece locating device for a corner shear machine which serves for determining a required position prior to starting a shearing operation when it is to be conducted at a corner or on one side of a workpiece in the form of square or rectangular sheet material. The workpiece locating device includes a pair of symmetrically located grooves extending in a V-shaped form relative to a center line extending through the center of dies across a table and a pair of rotary stoppers displaceably mounted on said grooves so as to slide to and fro therealong. The workpiece abutment edge of the respective stoppers is adjustable within an extent of an angle of 45 degrees in both the rotational directions relative to a plane extending at a right angle to the cutting edge of the dies. Measuring scales for both corner shearing and side shearing are fixedly mounted on the table in the vicinity of the grooves and in parallel to the latter.
