Abstract: A chuck assembly which can chuck thin and brittle workpieces that differ widely in size with high accuracy and reliability without warping them. The chuck assembly includes a tubular chuck body having three first cylinders and a plurality of second cylinders arranged along a circumference in a plane perpendicular to the axis of the chuck body at equal angular intervals. The cylinders have pistons adapted to protrude under oil pressure. The three first cylinders are also arranged at equal angular intervals. The chuck assembly further includes a pressure-biasing means for applying, independently of the oil pressure, pressure to the pistons of the first cylinders against a workpiece, so that the piston are less likely to be retracted by the reaction force from the workpiece. That is, this chuck assembly has a self-centering function.

Abstract: A kit for repairing a worn out of round aperture. The kit includes a template which is later utilized as a part of the repair. In a first embodiment, the template is precisely located by means of utilizing the bottom of the aperture which does not become out of round as does the upper portion thereof and is fixedly attached to the structure containing the out of round aperture. A sacrificial pin is inserted in the out of round aperture, centered therein by means of the bottom non-out of round portion and adhered thereto. A drill is then passed through the boring guide enlarging the out of round aperture to a true round bore and the sacrificial pin is drilled out at the same time. The boring guide is then removed and an enlarged precision pin is inserted into the re-bored aperture. The new pin is fixedly secured in the new aperture by any convenient means such as peening between the pin outer surface and the adjacent structure.

Abstract: A shank adapter for a rock drill, which is used to connect one end of a drill string to a rock drill, has a chuck end (10) made from one piece of material and an opposite, threaded end (16) made from another, different, material.

Abstract: A chuck includes a holder body, a clamp sleeve, and a large number of needle rollers. The holder body has a shank portion, a flange formed at one end of the shank portion, and a chuck sleeve that extends from the flange in the direction away from the shank portion. The clamp sleeve is fitted onto the outer circumference of the chuck sleeve such that the clamp sleeve is rotatable and axially movable relative to the chuck sleeve. The needle rollers are disposed between the chuck sleeve and the clamp sleeve over the entire circumference. The clamp sleeve is rotated to cause the needle rollers to revolve spirally along the outer circumferential surface of the chuck sleeve while rotating about their own axes in order to decrease and restore the diameter of the chuck sleeve. In the chuck, a groove having a predetermined depth is formed in the end surface of the flange opposite the shank portion such that the groove surrounds the base end of the chuck sleeve through which the chuck sleeve is joined with the flange.

Abstract: A security system for a document utilizing a plurality of fluorescent snippets on the document with other encryption data printed thereon with visible and invisible ink that becomes bright when subjected to certain light.

Abstract: A drilling apparatus capable of removing drill chips from a workpiece under vacuum. The drilling apparatus includes an elongated drill having a body and a shank. The body has an axial through hole to receive drill chips. The shank has a plurality of radial holes communicated with the axial holes of the body. A vacuum adapter is hermetically placed around the shank and includes a cylindrical hollow body. The hollow body of the adapter includes a radial through port. The radial through port has one end communicated with the radial holes and the other end communicated with an external source of vacuum through a vacuum hose. A cylindrical extension unitarily extends from one end of the hollow body of the adapter and includes an annular projection. The shank has a corresponding annular groove to lockingly receive the annular projection in order to lock the adapter against axial displacement relative to the drill.

Abstract: In order to provide a bookmark for a book, a method of making a book includes the step of applying a releasing adhesive to an inner surface of a front or rear cover having an initially greater width. The outer portion of this cover is then folded inwardly along a fold line so as to be in generally confronting relation with the inner surface of that cover to cause the width after folding to generally correspond to the width of the other cover. The outer portion of that cover is folded along the fold line so as to place the releasing adhesive in adhesive contact with confronting surfaces of both the folded outer portion and the remainder of that cover to adhesively secure them together after they have been folded into confronting relation.

Abstract: A wallet card comprised of front and back transparent exterior surface panels, front and back core panels, and an elongate internal sleeve is disclosed. The outward-facing surfaces of the core panels bear personal medical information, and a flexible strip thermometer is stowed within the sleeve. Registering apertures are provided in the core panels, these being sized to accommodate a plurality of microfilm chips bearing further personal medical information. Thus, a display window is defined in the wallet card wherethrough the microfilm chips may be read.

Abstract: The drawing has a background (10) composed of at least a first region and a second region juxtaposed. Each of said regions comprises its own geometrical drawing so that the first region has a color density which is stronger than that of the second region, said second region forming a pattern. An overprint (20) corresponding to said overprint is printed over the second region, said overprint (20) comprising geometrical drawings different than that of said second region and in a color chosen to compensate the difference of color density between said regions, so that the safety drawing appears uniform and with no pattern to the naked eye, but said pattern is clearly brought out and in another color than that of the first region on a photocopy of the safety drawing.

Abstract: A metal ring binder is improved by adding at least one auxiliary spring for supplementing the spring action of the spine upon the blades to which the rings are attached, so as to increase the closing force of the rings.

The binder including a spiral coil having tapered ends, each of the ends of the coil having an area width for receipt of a removable locking element. A removable locking element for securement to binding element about the area of reduced width to prevent the unintentional unbinding of the binder when secured to the coil and to allow the user to unbind the binder when the locking element is removed.

Abstract: A helically fluted twist drill device is disclosed for cutting materials. The device comprises a shank having a first and a second end. A cylindrical core has a first diameter and a first and a second extremity, the core extending coaxially relative to the shank and from the second end of the shank, the second extremity defining a point. At least three portions extend helically outwardly away from the core so that the portions define a second diameter. The arrangement is such that adjacent portions define therebetween a surface of a helical flute. Each of the portions further define a helical bore connected to a source of a cutting fluid for permitting a flow of the cutting fluid through the bore from the shank towards the point. The arrangement is such that in use of the device, the cutting fluid conveys the materials from the vicinity of the point through each flute towards the shank. The first diameter has a dimension within a first range which is 20-35% of a dimension of the second diameter.
