Abstract: The invention relates to a method for on-machine winding of a web (W), in which method a Pope-type reel drum (10) or corresponding reeling means is used and over which the web (W) to be wound is conducted. In the method, new reel spools (11) are brought into contact with the reel drum (10), after which the web (W) is conducted from the fully wound roll to be wound onto the new reel spool (11). In the method primary forks (14), when in their upper position, pick up an empty reel spool (11A,11B) without any auxiliary equipment. Guided by the primary forks (14) and supported on support plates (17) attached on the primary forks (14), the empty, preaccelerated reel spool (11B,11C), is brought into nip contact with the rotating reel drum (10) and through the nip of which the web (W) to be wound runs, and is wound round the reel spool (11) at the nip contact. The support plates (17) remain in such a position while the primary forks (14) are being lowered that the contact pressure between the reel spool (11C-11E) and the reel drum (10) remains substantially constant while the primary forks (14) are moving from the upper position to the lower (see vector diagrams, Fig. 2). When the primary forks (14) are in the lower position, the support plates (17) turn into such a position that they may pass the reel spool (11), which is already positioned on the reeler tracks (12), when the primary forks (14) are moving back into their upper position, and the above steps are repeated when it is time to exchange reel spools (11) again and the support plates (17) are ready to receive one. The invention also relates to the apparatus used in the method.

Abstract: In a plurality of writing units (40) disposed on a printing face of a magnetic head, there exist magnetic cores for generating forward magnetic field which directs to a magnetic display sheet from the printing face and magnetic cores for generating backward magnetic field which directs to the printing face from the magnetic display sheet. Those magnetic cores are arranged in such a manner that a predetermined number of consecutive first magnetic cores and a predetermined number of consecutive second magnetic cores are alternate. Thereby, magnetic saturation of a yoke may be relaxed and occurrence of ghost is suppressed in non-printed dots, and high quality magnetic printing may be realized. <IMAGE>

Abstract: High molecular weight polyanhydrides, defined as polyanhydrides having a molecular weight average greater than 20,000 or an intrinsic viscosity of greater than 0.3 dl/g in an organic solvent at room temperature, are formed by melt polycondensation of highly pure isolated prepolymers under optimized reaction conditions, particularly time and temperature with removal of the condensation product. Higher molecular weights are obtained by inclusion of a catalyst with the prepolymers in the melt polymerization. Catalysts used for transterification, ring opening polymerization and related polymerizations may be utilized. The high molecular weight polyanhydrides have improved physico-mechanical properties and are especially well suited for biomedical applications, particularly in controlled release devices for drug deliver.

Abstract: An assembly for producing a finished shape for a rod after the last rolling stage of a multi stand steel mill. This apparatus provides an operation for correcting minor surface irregularities and shape distortion of the rod as it exits from the finishing roll stand. The apparatus consists of four rollers mounted in an assembly which resembles a roller entry guide except that the rollers are capable of producing changes in shape of a work product passing therethrough. The orientation of the roller axis is slowly and constantly changed to prevent wear distortion of the rollers which may result when the rollers are required to roll a malformed product from fixed roller axes. The rollers may be driven in some circumstances.

Abstract: Due to the limited structural integrity of the ion exchange membrane, operation at pressure gradients exceeding about 200 psi can cause electrolyzer failure due to the ion exchange membrane being physically forced into the holes of the screen set forming the chamber on the lower pressure side of the ion exchange membrane. Utilizing a porous sheet between the anode electrode and the screen set provides additional structural integrity to the ion exchange membrane and allows simultaneous dual-directional flow of water to the anode electrode while oxygen flows from the anode electrode, thereby allowing high pressure gradient operation.

Abstract: A method and apparatus for vertically interconnecting stacks of silicon segments. Each segment includes a plurality of adjacent die on a semiconductor wafer. The plurality of die on a segment are interconnected on the segment using one or more layers of metal interconnects which extend to all four sides of the segment to provide edge bonding pads for external electrical connection points. After the die are interconnected, each segment is cut from the backside of the wafer using a bevel cut to provide four inwardly sloping edge walls on each of the segments. After the segments are cut from the wafer, the segments are placed on top of one another to form a stack. Vertically adjacent segments in the stack are electrically interconnected by applying electrically conductive epoxy to all four sides of the stack. The inwardly sloping edge walls of each of the segments in the stack provide a recess which allows the electrically conductive epoxy to access the edge bonding pads and lateral circuits on each of the segments once the segments are stacked. The stack of electrically interconnected segments is then mounted below the surface of a circuit board and electrically connected to circuits on the board by applying traces of electrically conductive epoxy between the bonding pads on the top segment of the stack and the circuit board. <IMAGE>
