Abstract: A security device for securing a first object having an aperture to a second object. The security device includes a scissor locking unit for securing the device to the first object and a cable adapter. The scissor locking unit comprises a locking mechanism having a shaft that is rotated between an unlock position and a lock position, a cam connected to said shaft for rotation therewith and a scissor pivot assembly connected to the cam for translating the rotary motion of the cam into linear motion of a pair of scissor arms in the scissor pivot assembly. The pair of scissor arms will be in an overlapping closed position when the locking mechanism is in the unlock position allowing the scissor arms to be inserted into the aperture in the first object. The pair of scissor arms will be in a spread apart open position when the locking mechanism is in the lock position preventing the scissor arms from being withdrawn through the aperture in the first object so as to secure the device to the first object.

Abstract: A door key is held in a tray which is slidably installed in a container. The tray is retained in the container by a form member pivotally mounted on the container which engages a latch on the tray. A shackle is removably attached to the container for use in retaining the container to a door knob or the like. The shackle has a notched arm which engages a fork member pivotally mounted on the container, thereby retaining the shackle in a closed position. A motor which rotatably drives a drive gear is mounted in the container. When the motor is driven in a first direction, the drive gear drives a tapered release wheel which operates to release the fork member from engagement with the key tray latch, thereby permitting the key tray to be removed. When the motor is driven in an opposite direction, the drive gear drives a second tapered release wheel so as to disengage the notched arm of the shackle from its associated fork member, thereby permitting the shackle to be moved to an open position.

Abstract: A structure of a ball return piece and its process of manufacture, and more importantly to the return piece of the internal circulation type ball screw system. The guide groove of the return piece is formed in the shape of a closed circular pipe to provide a precise pipe diameter for guiding the ball in a gliding fashion past the return piece. The return piece is produced by monoblock casting for ensuring enough strength to endure the strong impact stress upon it generated during the circulation of the balls and for preventing damage to the return piece. Moreover, since the guide groove of the return piece is to be formed in the shape of a closed circular pipe, a precise pipe diameter is required and can be achieved by precision lost wax casting. This provides the ball with stable guidance when passing the return piece.

Abstract: Precise cutting of pattern strips and pattern pieces from lace and similar patterned fabrics requires correct mutual positioning of the fabric and fabric cutter for precise alignment with the boundary of the pattern pre-existing on the fabric. Patterned fabrics and especially loosely-woven lace are liable to randomly variable stretching and slippage which makes it impossible to cut under the direction of an externally imposed pattern program without regard to the instantaneous location of the pattern pre-existing on the fabric. The invention comprises lace-cutting apparatus and a lace-cutting method including optical scanning of the lace, recognition of the pattern boundary, and mutual alignment of the fabric with the fabric cutter to trace the intended cut line. Different techniques for mutual movement of the fabric and cutter are employed according to whether the pattern boundary is re-entrant or not. Preferred forms of fabric cutter include a hot-wire cutter and a laser beam cutter.

Abstract: A sheet material 2 is cut with a round blade 10 and a notching blade 11. It is assumed that, in a straight section P1-P2-P3-P4, a distance between the end point P1 and the end point P2 is not shorter than a blade width W10 of the round blade 10, a distance between the end point P2 and the end point P3 and a distance between the end point P3 and the end point P4 are shorter than the blade width W10 and it is necessary to cut without cutting into a pattern piece indicated by shadow. A section between the end point P2 and the end point P3 can be cut without cutting into the pattern piece although overcut occurs on the end point P2 side, with the round blade 10 by aligning the leading edge thereof at the end point P3. A section between the end point P3 and the end point P4 is cut with the notching blade 11 because cutting with the round blade 10 causes a cut into the pattern piece at least from one of the end points.

Abstract: A method for trimming an inner ring from the neck flange of a blow-molded plastic bottle by extending a reverse punch into the bottle through the flange opening, elastically bending the flange into the interior of the bottle as the punch passes and withdrawing the reverse punch from the bottle and trimming a ring from the flange.

Abstract: In a cutting device having a moving (disc) cutter and a fixed cutter which extends in a cutting direction, wherein the moving cutter moves along the fixed cutter, thereby cutting a medium which is interposed therebetween, a presser member which is movable together with a medium pressing interlocking plate is lowered to press on the medium to fix the same at a portion close to a cutting position since a bearing attached to the moving cutter engages with the medium pressing interlocking plate to press down the same as the moving cutter moves. Since the moving cutter cuts the medium at this state, the cut edge of the medium can be excellent in linearity even if it has low rigidity in the outward-surface direction at right angles to the surface thereof. While the moving cutter does not cut the medium, the presser member is retracted to a standby position.

Abstract: A signature perforating device includes a perforating cylinder and a cooperating counter perforating cylinder. The perforating cylinder carries a perforating blade strip which is formed by a number of perforating blade elements.

Individual ones of these perforating blade elements can be removed from the strip for replacement without disruption to adjacent blade elements.

Abstract: A cutting device of packing apparatus includes at least three cutting blades arranged around the packing material expanding cylinder in a substantially equally-spaced manner. The cutting blades are rotatable about their own rotational axes in a synchronous manner for cutting off the continuous packing material along a circumferential slit formed on the cylinder. This simplifies the overall structure by eliminating a mechanism to move the blades around the cylinder. By using a number of blades rotatable in synchronization with each other, the time period for a single blade in contact engagement with the packing material to be cut off is substantially reduced and the efficiency of the cutting operation is enhanced. Due to the enhanced efficiency, the delay of time in the alternation of the feeding operation and cutting operation is lowered down.

Abstract: A media buffer capable of buffering two lengths of media, is fed a first length of media from an imagesetter at a first speed, and releases the media to a processor at a second speed. An input media sensor senses the media entering the buffer. Drive rollers take up the leading edge of the media at the imagesetter speed. Shortly thereafter a signal from an output media sensor located between the drive rollers and the processor, opens an input door to an input bin and stops the drive rollers. The incoming media continues to be fed by the imagesetter forming a first slack loop within the input bin. The imagesetter signals the buffer that the media has been cut, thereby actuating drive rollers to advance the media at the processor speed to a pair of rollers in the processor. A signal from the processor sensor opens an output door to an output bin. The drive rollers increase speed to transport the first piece of media from the input bin to the output bin thereby forming a second slack loop.
