Abstract: Engineering Change Notices are released frequently to replace an obsoleted item or a component in a bill of material (BOM) with one or more new item(s) or BOM compo­nent(s) that have different form, fit or function. When such Engineering change needs to be implemented, the process alerts the production planning system such as MRP (Material Requirements Planning) about a pending implemen­tation of an Engineering Change Notice. It then identi­fies the total available inventory of the obsoleted item or BOM component for allocation to future orders and automatically decrements available inventory based on open orders during Material Requirements Planning and triggers the implementation of the Engineering Change for the new item(s) or BOM component(s) after all available quantities of the obsoleted item or BOM component have been allocat­ed. This eliminates or minimizes wastage of available inventory of the obsoleted item or BOM component. The process provides visibility of customer data as well as consideration for alternate part numbers. The process also provides manual or automatic override capability based on predefined rules.

IPC: G06F3/06

Abstract: Using device-specific data carriers, for example magnetic tape cassettes, this method can be used for matching the device electronics to different data formats. The information on the storage allocation determining the format is recorded on a separate data medium which is inserted into the relevant read/write device instead of the user data medium. This format-determining data medium is automatically distinguished from the user data media by the fact that the associated data format deviates from the predetermined data format. When this distinction criterion is recognised, the information items relating to the new format are read into an electronically reloadable read-only memory and stored. The formatting/deformatting of a user data stream during the reading or writing of a user data medium is then carried out with the new format.

Abstract: The invention relates to a cold pilger rolling mill for fabrication of tubes by cold rolling over a mandrel by means of a pair of ring rollers rotatably mounted in an oscillated roll stand and having, over the majority of its development, a tapering reduction pass of essentially circular cross-section, the tube being fed stepwise and rotated about its longitudinal axis. In order to provide a pass design for a cold pilger rolling mill of the type described which does not have the disadvantages mentioned above, i.e. does not cause any stress peaks in the tube and improves both quality and output as well as increasing the life of the rolls, it is proposed that the reduction pass have an asymmetrical cross-section which deviates from the circular shape over at least part of the length of its development (Fig. 2). <IMAGE>

Abstract: A liquid crystal matrix display has plural picture elements (PELs) arranged in an X-Y matrix. Each PEL includes a thin film transistor (TFT) and a display electrode. Data lines are formed in the X direction and gate lines in the Y direction. To display one of eight gray-scale levels for each PEL, one of eight voltage levels is selectively applied to the data line. The voltage levels are applied through a combination of switches which operate under the control of a selector which translates a three bit address into the selection of one or more switches. By this means the number of voltage sources and switches to operate a cell is less than the number of gray-scale values.

Abstract: A distributed queue dual bus (DQDB) network has two, oppositely-directed, unidirectional busses (46, 48). A node (38) with data to send on one bus, can request access to that bus, by sending a bus request signal to all nodes (36) upstream on the bus (46). The bus request signal is sent to the nodes as part of the traffic flowing on the second bus (48). Each node (38) counts the number of successive bus request signals transported on the second bus (48). In a multiple priority system, multiple counts are maintained, one for each priority level. When a given or local node detects an idle slot on the first node, it may write data into that slot if there are no pending downstream access requests of higher priority and if the local node has allowed enough idle slots to pass since its last write operation to service access requests existing at the time of that operation at the same or higher priority levels.

Abstract: A unitary hand-held bar code scanner and reader produces an elliptical beam, oriented with its major axis along the direction of the bars, utilizing optics employing far field diffraction effects to shape the beam and maintain its elliptical aspect (length to width ratio) constant over a distance in front of the scanner were bar codes may be located. The optics eliminates parallax even though the photodetector and light source (preferably a laser diode) are located offset from each other on a board on which the optics are mounted. A housing assembly has channels which mount the board therein without shock absorbing devices. A digital microcomputer controller and peripheral devices regulate the optical power output from the laser diode and prevents catastrophic failure, if the electrical current through the laser diode exceeds safe limits. Digital control of the gain of the electronic circuits which provide the signals from which bar code information can be decoded and for the operation and control of a motor for oscillating a deflector which scans the beam across the code are also provided utilizing the microcomputer. The microcomputer also controls interface circuits to provide compatibility with auxiliary equipment and host computers which generate commands and requires data inputs of various polarity and format. 
     When the scanner is mounted on an upright support which extends from a base of a stand, the ratio of the number of generated pulses to the reflected pulses is computed for a succession of pulses (ten pulses for example). Then the presence of the label is detected and the system, implemented in an application program in the microprocessor controller of the bar code scanner initiates scanning of the bar code when the ratio differs from a certain value. Upon the detection of the code (a good read) or under conditions where the label is removed before detection, or is not removed after detection, the scanning mode is discontinued and the pulsing mode is again initiated. The pulsing mode is initiated continually to test for the presence of a object carrying a bar code label, when not scanning.

Abstract: Broadly, the present invention is directed to a diamond product comprising a core of diamond containing at least about 1 wt-% ¹³C and an epitaxial diamond coating on said core containing at least 1 wt-% less ¹³C than is contained is said diamond core. The diamond core will have a lattice parameter that is smaller that the lattice parameter of the diamond coating. When the coating is forced to grow epitaxially so that it must have the same lattice constant as the diamond core, the coating will be placed under compression. Since ¹³C diamond has the smallest lattice parameter known and the lattice parameter of diamond is a function of isotopic composition, the diamond core should contain more ¹³C than is contained in the coating in order for the coating to be placed under compression. Accordingly, the diamond core can be composed of natural or synthetic diamond having a natural isotopic composition and the coating can be ¹²C or ¹³C. Alternatively, the core can be ¹³C and the coating ¹²C. When mixtures of isotopes comprise the core and/or coating, their composition should vary by at least 1 wt-% ¹³C with the higher incidence of ¹³C isotope being located in the core.

Abstract: The present invention refers to an improvement for delignifying a lignocellulosic pulp by means of oxygen wherein ethanol is used as an additive and the process is carried out at high temperature thereby obtaining a higher reduction of lignin content of the lignocellulosic pulp, that is, a higher reduction of the Kappa Number in comparison with conventional processes without, however, prejudicing the pulp quality. The use of the present invention provides a pulp which, when subjected to subsequent bleaching sequences, will require a lower amount of chloro compounds in order to achieve the desired whiteness and will also exhibit a high viscosity thus rendering a product with good resistance properties.
