  • Patent number: 6267037
    Abstract: An underwater apparatus for servicing subsea pipelines provides a telescoping frame which can be lowered to the vicinity of the pipeline. The frame has an open section so that it can straddle the pipeline and outer jacket and fixate itself releasably so that it can be selectively repositioned. A cutting apparatus is secured to a telescoping sub frame. The cutting structure can be rotated about the longitudinal axis of the sub frame, as well as advanced along the direction of the longitudinal axis of the frame due to the telescoping feature of the sub frame. The cutting structure can also be moved pivotally about an axis of rotation which is outside and generally perpendicular to the longitudinal axis of the pipe. Thus, combining the telescoping feature with the pivoting feature and the feature of being able to rotate about the longitudinal axis, a variety of different cuts can be made.

  • Patent number: 6125520
    Abstract: In a process and apparatus for forming parts from a sheet of metal stock material so that they can be separated by a shake-and-break operation, elongated holes are punched in the sheet to separate the first part from the second part except at at least one shake-and-break location. At the shake-and-break location, a frusto-conical shape punch and die punch an opening on either side of a center tab connecting the parts. The wider ends of the frusto-conical shape holes face the tab, and the narrower ends adjoin the elongated holes and have the same width as such holes. In such a manner, the points where ends of the tab connect to the first and second parts are located in recesses located to the outside of the edges of the elongated holes. When the pieces are subsequently separated in a shake and break process, any residual burrs from where the tabs separate from the parts are located in the recesses, rather than along the edges of the part, and do not need to be removed.

Edge contours are then cut into the strip material if they are not already pre-provided. The positions of any edge contours are detected by a sensor 18 which provides relevant information to a CPU 40. On the basis of this information and other pre-provided information on the type of blind being made guide holes and notches and the ends of the slats are cut ensuring that the contouring and the guide holes and ends do not interfere with each other.

  • Patent number: 5937518
    Abstract: A finished workpiece of malleable metal containing a saw cut which does not require deburring because the small burr on the exit side of the cut is concealed within a three sided notch. An elongated notch, closed on three sides, is formed on the side of the blank workpiece from which the saw blade exits. The depth of the cut is adjusted so that the bottom of the cut, together with its attendant burr, intersects with the notch. The burr is thus attached to a wall within the notch. The width of the notch is adjusted so that the anticipated tolerance in the depth of the cut (and thus the location of the bottom of the cut) is accommodated. The width of the notch is such that the bottom of the cut will intersect the notch at any location within the anticipated tolerance envelope. The depth of the notch is sufficient to conceal the burr.

  • Patent number: 5873292
    Abstract: An improved elongated holddown bar for use in conjunction with a power corner notcher having a table which defines a horizontal working surface. The notcher includes a clamp means adjustably positionable on, and connectable to, the table atop the work surface which immobilizes the holddown bar in a selected position to establish either of two upright side edges of the holddown bar against which a piece of sheet metal may be positioned. One of these edges includes a recess formed entirely therealong which defines a recessed upright abutting surface and a horizontal holddown surface spaced above the working surface a height substantially equal to the thickness of the sheet metal whereby the notching operation into the edge of the sheet metal cannot substantially buckle or distort the edge of the sheet metal.

  • Patent number: 5775189
    Abstract: A cutting head is provided also with a notching blade to enable it to cut a length shorter than the blade width of a round blade. In order to eliminate the need for compressed air supplying equipment and simplify the mechanism thereby to make it compact and light weight, an angular displacement servo motor is used as a common drive source for causing angular displacement of the round blade and angular displacement of the notching blade. A cam motor causes a round blade cam and a notching blade cam to make angular displacement thereby to selectively cause the round blade and the notching blade to work on sheet material placed on a cutting table an cut it.

  • Patent number: 5740713
    Abstract: A notch cutter provides a first pair of inwardly facing shear edges in a V. A second pair of outwardly facing shear edges make an almost complementary V with a slightly smaller convergence angle. One pair of shear edges is caused to contact respective ones of the other pair along contact points moving from the entrance of the notch to the apex of the notch. One pair of shear edges is resiliently mounted relative to the other. When used to separate strips and form the ends of the separated strips, the V's of the first and second edge pairs may be truncated since the shear edges need only be wider than the strips on which they act to form their separating and edge shaping functions.
