Abstract: The present invention provides an automated method for forming indented embossed edges around along the periphery of a light aperture for mounting a panel light's pane and frame assembly therein. A panel blank made of sheet metal is mounted on the table of an automated CNC punch press. Next the light aperture is scored in the blank using the punch press to punch out elongated slots between widely spaced apart bridge tabs forming an aperture blank within and connected to the panel blank by the spaced apart bridge tabs. Next the indented embossed edges are formed with two cooperating punch and die sets. A first right angled die set is used to form the four corners. A second straight bar die set is used with an automated nibbling function of the CNC punch press machine to form the linear extending sides of the indented embossed edge. The cooperating punch and die sets are designed to form an edge and not punch through a hole in the blank.

Abstract: An optical fiber cleaver is disclosed wherein a blade applies a pre-set force to an optical fiber to form a notch in that optical fiber. In a preferred embodiment, a spring applies a pre-set force to the blade such that should an undue amount of force be applied to the fiber from the blade, the blade will overcome the spring force and not move towards the fiber any further. The cleaver is preferably formed from two pivotally connected handle portions each including holder portions which come into mating contact with each other to provide a stop against further pivoting movement. At that time, the blade is forced into the optical fiber to cleave the optical fiber. In a further feature of this invention, an optical fiber guide provides a stop between an insulated portion of the optical fiber, and a stripped portion. The optical fiber guide is adjustable to adjust the distance between the end of the insulation and the location of the notch.

Abstract: Lightweight, portable apparatus for cutting a wide range of materials available in sheet form, such as matboard, glass, light plastic, and leather. The invention lies in the unification of its cutting tool guide tract with the means of fixing in place the material to be cut. Four pegs are attached to the base of the apparatus for aligning the sheet to be cut. Equally important is the means by which it is automatically held in place during the cutting operation. Pieces of foam rubber or the like are inlaid in the base of the apparatus so that when the operator is pressing down on the cutting tool the resultant force normal to the supporting surface is sufficient to prevent lateral motion of the apparatus. Thus, no bulky and awkward clamping devices need to be used to affix the cutter to its supporting table.

Such regulation provides for a more precise depth of score reducing adverse effects thereof.

Abstract: There has been provided a cutting device utilizing a fixed cutting edge and a movable roller axially mounted on a radial arm parallel to the cutting edge. The roller has an outer surface which is also parallel to the cutting edge.

The radial arm and roller carried thereby swings between extreme stop positions, and a cut is made each time the roller swings in proximate spaced relation to the cutting edge. The frequency of the swings of the radial arm, or the speed of the composite past the blade determines the length or distance between the cuts.

Abstract: A dual-knife device for scribing or scoring a wood workpiece before sawing it with a motorized circular handsaw or other saw. The scoring insures a clean saw cut without splintering the wood at the edges, as is required in trimming veneer doors and wall panels. A guide bar is clamped to the workpiece to guide the saw and the scoring device. Prior to sawing, the scoring device is drawn by hand across the workpiece, guided by the same guide bar. The scoring device comprises a pair of knife blades mounted close together on a frame. The knife blades cut two parallel scribe lines or scores into the wood surface, one on each side of the kerf to be sawed. When the saw cut is made, the score lines prevent the saw blade from splintering or feathering the surface of the workpiece along the kerf line, insuring a clean cut.

Abstract: This disclosure describes a device for repeatably scribing a V-shaped scratch having sharply defined dimensions on the interior surface of a nuclear reactor fuel rod tube. A cutting tool having a V-shaped cutting tip is supported within the fuel rod tube so that the V-shaped cutting tip can be pivoted about an axis and scribe a scratch on the interior surface of the fuel rod tube. Lengthwise the scratch runs parallel to a line drawn through the axis of the fuel rod tube and is in the shape of an arc, and widthwise the scratch is V-shaped. This shape is used because the dimensions of the scratch can be plugged into appropriate formulas to calculate stress intensity of cracks in fuel rod tubes. Since the fuel rod tubes which are to be scribed may be radioactive, the scratching assembly is designed for use in a fixture which allows it to be operated in a cave by remote control handling devices.

The control system further comprises X-channel and Y-channel program-decoding means for converting the signals played back from the magnetic-tape unit into signals suitable for controlling the motion of the cutting tool. The control system also includes conductive means interconnecting the components of the system.
