摘要： A method for explosive cutting using converging shockwaves, and an explosive cutting device are disclosed. The method includes providing a projectile with an explosive charge, positioning the projectile over the object so it extends along an intended line of cut, and detonating the explosive charge so that the projectile is accelerated toward the object, wherein the projectile either impacts on the object and the projectile includes a wave-shaping element which is shaped such that the impact generates converging shockwaves in the underlying object to be cut causing a crack to be propagated through the object along the intended line of cut; or impacts on a wave-shaping element in contact with the object, the wave-shaping element being shaped such that the impact generates converging shockwaves in the underlying object causing a crack to be propagated through the object along the intended line of cut.

摘要： In a method and apparatus for cutting expanded graphite sheet material, at least one cutting tool is urged against the sheet(s). The cutting tool has at least one ridge extending therefrom, that includes a substantially tapered cross-section having sloping sides and an edge surface. At least a portion of the sheet material is displaced as the ridge is urged against the sheet. A region of the sheet material in contact with the ridge is compressed so that the density of the region reaches or exceeds the breaking density of the sheet.

摘要： The present invention involves a method for severance of materials made of polycarbonate, polycarbonate laminate and acrylic/polycarbonate laminate, such as the materials from which many of today's military aircraft canopies are manufactured. A method of severing a section of an aircraft canopy so as to allow aircrew egress is necessary for aircrew safety. Past severance methods focused on fracturing materials using the shock waves created by explosive charges placed on, near or in the canopy material. These methods are effective for fracturing canopies manufactured from acrylic type materials, however, they are not reliable in severing polycarbonate type materials. The present invention utilizes a linear shaped explosive charge placed at a predetermined distance or stand off from the polycarbonate material to be severed. The coreload of the charge is determined such that the minimum coreload necessary to effect severance of a given thickness of polycarbonate material is utilized. A retainer is placed around the charge and affixed to the material such that the charge is at the proper stand off from the material. The retainer surrounds the back side of the charges but leaves open space between the charge and the material to be severed. Upon detonation, the charge creates an explosive cutting force, or jet blast, that severs the polycarbonate material. The present invention also involves methods for intersecting explosive charges about a pattern to be severed and methods for transferring detonation between such intersecting explosive charges.

摘要： Apparatus having two spaced rolls with a plurality of intermeshed disc-like teeth. The rolls form a nip into which an absorbent board is fed for partial slitting. The board is comprised of both long and short fibers. The apparatus separates the short fibers at each slit while leaving a number of long fibers intact to maintain a unitary structure. Advantageously, the teeth of one roll form gaps slightly wider than the thickness of the long fibers with the teeth of the other roll to permit passage of the long fibers.

摘要： An explosive linear cutter for cutting materials comprising an explosive rge sheathed in a metal covering, a support for said charge surrounding the covering except for a slot facing the target material to be cut. Separation of the target material is effected by propelling a fragment of metal sheath at high velocity through the slot and into the target upon detonation of said explosive charge to thereby achieve a clean highly directional cut along a desired separation line.This abstract is for the purpose of providing a non-legal brief statement to serve as a searching tool and is not intended to limit the scope of the invention as disclosed herein nor limit the scope or fair meaning of the appended claims.
