Abstract: The invention concerns a method and apparatus for measuring web tension. The tension of a moving web is measured by lo­cating close to the web (14) a gauging bar (1), which has its outer surface curved in the machine direction of the web (14) and carries pressure measurement sensors (2) in holes (3) formed into the bar. An air-cushion is formed between the moving web (14) and the curved surface, wherein the pressure is proportional to the tension of the web (14). The tension of the web (14) is measured in an indirect way by gauging the air-cushion pressure. The apparatus capable of implementing the method has an apparatus (7) required for the generation of a reference pressure, and the pressure measurement apparatus is used for measuring the pressure difference between said reference pressure and the air-­cushion pressure.

Abstract: A tunable drain-biased transresistance (DBT) device for generating accurate linearly variable RC values employs first (M1) and second (M2) matched MOS transistors connected in first and second series circuits with third (M3) and fourth (M4) matched MOS transistors, respectively, across the terminals of a source of supply voltage. A differential amplifier (7) has first and second input terminals connected to respective drain electrodes of the first and second MOS transistors and an output coupled via a feedback circuit to at least one of its input terminals. A pair of signal input terminals are connected to the gate electrodes of the first and second transistors so that said input terminals operate into a high impedance. A source of adjustable bias voltage (V B ) is connected in common to the gate electrodes of the third and fourth transistors thereby to supply adjustable bias currents (I B ) to the drain electrodes of the first and second transistors so as to bias these transistors into their triode regions. The tunable DBT device thereby exhibits a wide dynamic linear input range. The resistance of the device is adjustable in a linear manner by control­ling the drain voltage of the first and second transistors by adjustment of the bias current (I B ).

Abstract: A pattern-matching network is merged with a pre-existing RETE network without recompiling the whole network, while still matching existing data. Permanent, temporary , full and partial merging operations are described, depending on the origination of match patterns among LHS, on demand (procedural programming), or top level. The merge process combines functionally identical nodes from the networks for reducing the number of nodes in the resulting network. The merger process produces so-called alpha and beta synapse nodes; alpha synapse nodes have pointers to top nodes, while beta synapse nodes have pointers to a drain node, which is a node in the grafted RETE portions of the resulting network and to source memory nodes in the pre-existing RETE network. The algorithm for obtaining a set of synapse nodes without duplication of any logic connecting paths is described. The synapse nodes are used in updating a grafted network, also can be a suspended portion, upon completion of the merger. Two network updating algorith­ms are presented.

Abstract: A disc file system is described in which the disc space is divided into very large blocks of at least 64Kbytes. A large file is allocated a whole number of these large blocks, contiguously where possible. Small files reside in small file areas each of which is composed of a number of large blocks. Space in these small file areas is allocated in multiples of a small block size (e.g. 4Kbytes). 
     The use of large and small blocks reduces the wastage of space that would occur if small files were written into large blocks. The amount of head movement when reading large amounts of data from large files is reduced because of the large block size and because the large blocks are allocated contiguously.

Abstract: An anchoring bolt (4) whose anchoring area (6) has an at least partly widening cross-section (8) in the insertion direction is anchored in a recess (2) of a structural part (1) by means of hardening mortar compounds (3). Means are provided which prevent the adhesion between anchoring area (6) of the anchoring bolt (4) and hardened mortar compound (3). Owing to this means serving to prevent the adhesion, a relative movement between anchoring bolt (4) and hardened mortar compound (3) is possible in such a way that, in particular when used in the cracked tension zone of structural parts (1), compressive forces resulting via the widened cross-section (8) of the anchoring bolt (4) and deviating from the axis of the anchoring bolt (4) are passed into the hardened mortar compound (3) while maintaining the bond with the structural part (1).

Abstract: Porous chitosan beads are used as carriers for immobilization of polynucleotide phosphorylase (PNPase). Immobilization of PNPase to the porous chitosan bead carrier can be effected by contacting the enzyme with the carrier in water or in a buffer solution such as phosphate or borate buffer solution, preferably at room temperature. The thus obtained immobilized enzyme is contacted with a solution of nucleoside, e.g. cytidine-5′-diphosphate or inosine-5′-diphosphate, to produce the corresponding polynucleotide, e.g. poly C or poly I. The yield of polynucleotide is thus improved and the costs reduced. Also, the reaction can be conducted by a continuous process and the chain length of the polynucleotide can be controlled.

Abstract: A substantially ghost-free head-up display for a vehicle such as an automobile is disclosed. A head-up display unit projects the image beam toward the vehicle windshield for reflection back toward the viewer's eye. The windshield is slightly tapered so that the reflected images from the outside and inside surfaces of the windshield are reflected at slightly different angles, chosen so that the images substantially overlap at the viewer's eye. Use of a properly selected taper results in substantially ghost-free operation. The taper can be achieved by sandwiching a tapered layer (40C) of transparent material such as polyvinylbutyral between two windshield singlets (40A, 40B).

Abstract: Methods and apparatus for inspecting surface features of a substrate. In each configuration, at least one TDI sensor is used to image the portions of interest of the substrate, with those portions illuminated either with substantially uniform illumination or critical illumination. In one configuration, a substrate, is compared to the expected characteristic features prestored in a memory. In a second configuration, a first and second pattern in a region of the surface of at least one substrate are inspected by comparing one pattern against the other and noting whether they agree with each other without the prestoring of an expected pattern. This is accomplished by illuminating at least the two patterns, imaging the first pattern and storing its characteristics in a temporary memory, then imaging the second pattern and comparing it to the stored characteristics from the temporary memory. Here, the comparison reveals whether the two patterns agree or not. Then the comparisons continue   sequentially with the second pattern becoming the first pattern in the next imaging/comparison sequence against a new second pattern. Each time the comparison is performed, it is noted whether or not there has been agreement between the two patterns and which two patterns where compared. After all of the patterns are sequentially compared, the bad ones are identified by identifying those that did not compare with other patterns in the test process. This inspection technique is useful for doing die-to-die inspections, as well as repeating pattern inspections within the same die. A variation of the second configuration uses two TDI sensors to simultaneously image the first and second patterns, thus eliminating the need for the temporary memory. In this configuration, the two patterns are simultaneous imaged and compared, then additional patterns are compared sequentially, in the same manner with the results of the comparisons and the pattern locations stored determine which patterns are bad when the inspection of all patterns is completed.
