The first arm is moved axially outwardly until the first end of the roll is stripped off the first axle journal. The second arm is then also moved axially outwardly until the roll of material is stripped off the second axle journal.

Abstract: Three fundamental and three derived aspects of the present invention are disclosed. The three fundamental aspects each disclose a process sequence that may be integrated in a full process. The first aspect, designated as “latent masking”, defines a mask in a persistent material like silicon oxide that is held abeyant after definition while intervening processing operations are performed. The latent oxide pattern is then used to mask an etch. The second aspect, designated as “simultaneous multi-level etching (SMILE)”, provides a process sequence wherein a first pattern may be given an advanced start relative to a second pattern in etching into an underlying material, such that the first pattern may be etched deeper, shallower, or to the same depth as the second pattern. The third aspect, designated as “delayed LOCOS”, provides a means of defining a contact hole pattern at one stage of a process, then using the defined pattern at a later stage to open the contact holes.

Abstract: A cotton sample is subjected to noninvasive x-ray microtomographic image analysis in order to recognize cotton contaminants in the cotton sample. The cotton contaminants are detected and classified using an x-ray microtomographic system. Once the cotton contaminants in the cotton sample are detected and classified, the cotton sample may be graded based on the type and amount of cotton contaminants present.

Abstract: The present invention on embodies a device and method for creating a bloodless field at an incision site in a blood vessel. The invention includes a perfusion tube for allowing perfusion of blood past the incision site. A pair of conical occlusive members are mounted on either end of the perfusion tube for preventing blood from flowing into the surgical site. A tubular stem depends from the tube, and includes a movable stopper which may be moved between a first position for blocking blood flow through the perfusion tube, and a second position for enabling blood to perfuse through the perfusion tube. With the movable stopper in the first position, a first end of the device may be inserted through a small incision into the upstream side of a blood vessel so that the blood flow is blocked. The second end of the device may then be inserted in the downstream side of the incision. The stopper may then be moved to the second position so that blood is free to flow through the perfusion tube.

Abstract: A two-piece handle is provided having a male handle half and a female handle half, each of which may be formed separately by molding, machining, or other processes. The male handle half includes a projection near the rear of the handle, and has a first hole in the projection for receiving a leaf spring rod. The female handle half has an integral spring holder which includes a recess for receiving the projection of the male handle half. The spring holder has a second hole for receiving a leaf spring rod through it which intersects with the recess. When the projection of the male half is fitted into the recess of the female half, the first hole and the second hole line up sufficiently to enable the insertion of the leaf spring rod. When the leaf spring rod has been inserted, it aids in retaining the male handle half in an assembled state with the female handle half, while also serving a spring for the blade locking mechanism.

Abstract: In a method and apparatus for the removal of trimming strips located on point needles, it is intended to convey the trimming strips from a cylinder rotating at high rpm, in particular a blade cylinder of a scissors cut device, to a disposal device. This is achieved in an operation in which in that the speared trimming strips are completely pushed off the point needles by stripping fingers acting on them from beneath. The removed trimming strips are supplied to a disposal device.

Abstract: A packing is secured to a cylinder of a rotary printing machine. The ends of the packing have suspension strips that are placed in a cylinder channel. A tightening strip is movable radially in the cylinder channel. One suspension strip is held, by one side of the tightening strip, in a channel groove in the cylinder channel. The other suspension strip is movable radially in the cylinder channel by radial movement of the tightening strip.

Abstract: An arrangement for the attachment of a paper web leading edge on a paper supply roll utilizes a rapidly setting material, such as a hot melt adhesive in the form of beads, drops or dots to attach the leading edge of the first paper web layer to the second layer. The drops or beads may bridge the junction of the leading edge with the second layer. Strings or threads, which are attached to the dots of the rapidly setting adhesive, may bridge the juncture.

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. These elements are held in place on the perforating cylinder in a profiled blade holding strip. Individual ones of these perforating blade elements can be removed from the strip for replacement without disruption to adjacent blade elements.

Abstract: A speed control device for a multi-motor drive mechanism for driving printing press components is described. The speed control device allows the control of drive motors experiencing different instantaneous loads. This is achieved in accordance with the invention by assigning the motor having the greatest load fluctuation as the master, with the other motors assigned as slaves. A signal indicative of the demand experienced by the master is smoothed and used to control the slave motors.

Abstract: A spray dampening device for a printing press utilizes a plurality of magazines, each of which is assigned to cover a spray area on a dampening cylinder. Each magazine includes at least one active dampening fluid spray nozzle and one reserve, freshly prepared spray nozzle. The active nozzle can be moved out of its active position and can be replaced by the reserve nozzle if a reduction in the print quality of the press is noted.

Abstract: A printing system for a multi-color web-fed rotary printing press utilizes a plurality of printing system units that are arranged in a vertical array. Each printing system unit includes a left printing unit and a right printing unit. The left or the right units are supported in a frame which is shiftable horizontally with the respect to the frame that supports the other units.

Abstract: A leading edge of a paper web supply roll is prepared for utilization in a flying web splice. The paper web supply roll is supported adjacent a work carriage that is movable transversely across the face of the supply roll. As the work carriage moves across the web, a leading edge of the web is cut, spaced adhesive labels and a double sided adhesive splice tape are applied, and the lateral edges of the web adjacent the web leading edge are provided with angled lateral edge cuts.

Abstract: A signature to be folded in a folding device is first provided with a pre-fold that is formed along the intended fold line. The signature is conveyed through a linear guide where it is pre-folded. The pre-folded signature is then delivered to a folding device where it is folded by being caused to pass between a pair of folding rollers.

Abstract: A printing unit of a rotary printing press utilizes a "waterless" planographic printing plate which is fastened on a printing cylinder. This "waterless" planographic printing plate receives ink from a short inking unit and directly prints a material to be printed. An additional printing cylinder, that is also equipped with a "waterless" planographic printing plate, acts as the counterpressure cylinder.

Abstract: Point needles in a collecting cylinder are driven in a two stage extension process to initially needle or pierce the leading edge of a product web being cut. Once the cut has been made, the needle tips are moved further radially outwardly from the cylinder to secure the cut edge. As the signatures are transferred to a folding cylinder, the needle points are retracted along a single stage retraction curve which is different from the path traveled during the two stage extension process.

Abstract: A wide printed paper web is longitudinally separated into at least two partial paper webs after the last printing unit of a printing press and before being dried. The plural partial paper webs are dried in a drying device on separate or the same level. The partial paper webs are dried in a smudge-free manner and are free of longitudinal creases or folds.
