Abstract: A holder for a book, such as a paperback or hard cover book, comprises a stiff flat member creased to provide a central stationary panel corresponding to the spine of the book, and a pair of pivoted panels corresponding to the front and back of the book. A spring assembly comprises a plurality of long concave thin metal members connected together by a strip of tape and connected to the stiff flat member by a pop rivet. The ends of the springs are received by a pair of plastic sleeves which are stitched to the stiff flat member. The stiff flat member is covered by a vinyl sheet in such a way as to have a curved edge providing a radius of at least 1/16". A transparent strap connects to the opposite sides of the book holder and presses open pages of the book against the flat stiff member. The curved edge prevents the transparent strap from being cut by the book holder.

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.

Abstract: A method of fusing two or more pieces along an edge to produce a bound volume uses an activating agent which dissolves and mixes with a component present on the pieces, and thereby causes the edges of the various pieces to fuse together. The method is particularly useful for producing bound periodicals and magazines.

Abstract: A sheet supply inlet (4) receives sheets (3) one by one from a printing machine (2). A sheet gathering and registering mechanism (20) comprises a pair of sheet feed rollers (24A, 24B) arranged in the neighborhood of the sheet supply inlet (4) for successively supplying each sheet (3) from the sheet supply inlet (4) to the sheet stitching station (5) so as to lay the sheets (3) one above another in the sheet stitching station (5), and a guide plate (26) arranged adjacent to the sheet feed rollers (24A, 24B) for swing movement in such a manner that the guide plate (26) pushes the rear end of the top sheet (3) toward the stopper (12; 13) until the front end of the top sheet (3) abuts against the stopper (12;13) each time the sheet is supplied to the sheet stitching station (5).

Abstract: The invention concerns a drilling tool for machine tools. The drilling tool comprises a drill body with two chip-conveying grooves which are delimited at their flanks by helically curved ribs. Disposed at the end of the drill body is a drill head which comprises two segment parts, which are separated from each other by opposite axially aligned chip spaces, and two cutting plates which are each disposed in a recess in the segment parts in the region of an axially parallel radial chip-guide surface at different radial spacings from the drill axis with mutually partially overlapping working regions. At a transition point, the chip-guide surfaces merge into the flanks of the adjacent chip-conveying grooves. Disposed at at least one of the transition points is a transition surface which is gradually recessed so that it widens the cross-section of the chip space and merges into a flank of the adjacent chip-conveying groove.

Abstract: A seal is provided for notebooks and albums to prevent inadvertent opening of the rings and to prevent pilferage of paper, photo album insert sheets and the like. The seal is a continuous band or overlapped loop of plastic material which is heat-shrunk over the rings.

Two chip flutes extend in a helical manner over the chip removal part starting at the main cutting edges of the drill tip. The drilling tool is separated into two parts in the region of the chip removal part and consists of a base body which is connected to the drill shank as one part and an exchangeable tip made of a harder material which is connected to the drill tip as another part. The exchangeable tip is connectable to the base body in a form-fitting and/or frictional-fitting manner at an axial separation point.

Abstract: Methods for forming a rib on a cannula for cooperation with a safety cover which securably and reliably locks the tip of a cannula in an interior chamber within the safety cover. The cover comprises an elongate body having the interior chamber and an axial through hole which extends along the entire length of the body, through the interior chamber and through which the cannula is slidably received. Displacing elements are positioned within the interior chamber, each of which includes a hole for receiving the cannula therethrough, and which displaces upon retraction of the tip of the cannula, thereby preventing subsequent advancement of the cannula tip. The cannula includes a thickened rib adjacent to the tip, and the safety cover should correspondingly include an annular section in the rear portion thereof. The through hole extending through the rear portion has a diameter which is smaller than the thickened rib of the cannula whereby the cannula tip may not be retracted from the safety cover.

Abstract: There is disclosed a boring machine capable of achieving high processing precision and high processing efficiency. A table is mounted on a bed for reciprocal movement in right and left directions. A workpiece fixing device for fixing workpieces W of a semi-cylindrical shape is mounted on the bed. Cutting tools P and Q for cutting the workpieces W, a workpiece carry-in device and a workpiece carry-out device are provided on the table. The table is moved to a left side, and the workpieces W are placed on the workpiece carry-in means. Then, the table is moved to a right side to transfer the workpieces W to the workpiece fixing device. The table is again moved to the left side, so that each workpiece W is subjected to a boring processing by the cutting tools P and Q. The workpiece carry-out device receives the processed workpieces W, and then the workpieces W are unloaded from the boring machine by a workpiece unloading device, and are fed to a subsequent step.
