Abstract: 57 In the production of an optical fibre cable a core (3) of thermoplastics material is extruded with a plurality of longitudinally-extending grooves (15) in its outer surface around an electrical conductor (1) and is initially cooled: then following the introduction of one or more fibres (11) in at least one of the grooves the core assembly is passed through an induction heating unit (17) in which the conductor is heated to an extent sufficient to soften at least the adjoining region of the core, and the core is twisted to cause the grooves to take up a helical or periodically reversing helical path, and is again cooled to leave the grooves in that condition.

Abstract: An apparatus for manufacturing a building block is of the type having a mould box (1), and at least one core (3) rigidly mounted in the mould box by means of a spacer bar (4). At least a portion of the moulding surface of the core and/or the mould box is formed from a rubbery polymer. The polymer may be used as a coating (8) and/or the core (3) may be a moulding of the polymer. An undercut may be made in a block by providing a core (16) with an expandable resilient portion. The polymer may also be used to provide a cushion (8) under the lower edge of the mould box (1). 
     In the process using the apparatus the mould box (1) and core (3) are removed from uncured mould blocks after a very short time e.g. 1 to 60 seconds.

Abstract: Die Eisenoxidteilchen werden in einem Schachtofen (1) reduziert und die erhaltenen Eisenschwammpartikel werden einem Einschmelzvergaser (2) aufgegeben, wobei im letzteren unter Zuführung von Kohle und sauerstoffhältigem Gas ein Kohlefließbett gebildet wird, in welchem die zum Einschmelzen der Eisenschwammpartikel notwendige Wärme sowie das in den Schachtofen einzuführende Reduktionsgas erzeugt werden, und wobei das nach der Reduktion verbleibende Gichtgas aus dem oberen Teil des Schachtofens abgezogen wird und die mit dem Reduktionsgas und/oder mit dem Gichtgas ausgetragenen staubförmigen, hauptsächlich aus Kohle bestehenden Feststoffteilchen ausgewaschen werden. Um einen optimalen Umsatz der eingesetzten Rohstoffe bei gleichzeitiger Erhöhung des Wasserstoffanteiles im Reduktionsgas zu erreichen, eine nahezu vollständige Nutzbarmachung der durch die Gase ausgetragenen Kohleteilchen zu ermöglichen und die Temperatur des Reduktionsgases zu erhöhen, ohne Bindemittel für die Stäube zu benötigen und ohne daß die Gefahr von Betriebsstörungen und Staubexplosionen in Kauf zu nehmen ist, wird die Suspension der ausgewaschenen Feststoffteilchen eingedickt, in einen klaren Überlauf und einen konzentrierten Kohleschlamm aufgetrennt, der Kohleschlamm zu dem Einschmelzvergaser rückgeführt, mit Sauerstoff druckvergast und mittels im oberen Teil des Einschmelzvergasers angeordneten und gegen das Kohlefließbett gerichteten Brennern verbrannt.

Abstract: Method and compositions are provided for preparing and using pesticides, where the pesticides are encapsulated in non-proliferating cells. In one aspect of the invention, whole, i.e., unlysed, cells of a toxin (pesticide)-producing organism are treated with reagents that prolong the activity of the toxin produced in the cell when the cell is applied to the environment of target pest(s). In another aspect of the invention a heterologous gene is introduced into a cellular host, where expression of the heterologous gene results, directly or indirectly, in production of the pesticide. These cells are then killed under conditions which prolong the pesticidal activity when said cells are applied to the environment of a target pest. The thus treated cells can be used directly or after formulation for treatment of an agricultural host or environment of the host with the pesticide.

Inventor: HICKS JOHN WILBUR
IPC: G01D5/26
Filed: 1986-08-06
Abstract: A fiber laser sensor is comprised of two fiber lasers which are each optically coupled to a third fiber so that energy is exchanged between each of the laser fibers and the third fiber. The coupling is accomplished by arranging the laser fibers parallel to and on either side of a third fiber and properly spacing the three fibers to produce optical coupling along the length of the fibers. The central fiber ends are non-reflective so that light generated by one of the lasers and coupled to the central fiber is lost except for a small fraction of the energy transferred to the other laser. Accordingly, the structure operates with the least loss when the two lasers oscillate at a common frequency but 180° out-of-phase. The resonant cavities of the two fiber lasers are made non-identical by making the path length one cavity slightly longer than the other to produce Vernier tuning of the laser resonant frequency orders relative to each other with only one common resonant frequency. As this common frequency has the lowest losses, the structure will oscillate at that frequency. To further insure that only one output frequency is generated, methods are disclosed to insure that both cavities maintain oscillation with constant polarization. The device can be used as a sensor because the common laser output frequency is sensitive to changes in the optical path length of either or both of the laser cavities. Examples are disclosed in which several variables, including temperature, pressure or magnetic field strength, are used to affect the optical path length and thus the output frequency.

Abstract: A colour cathode ray tube is disclosed having a front assembly with a shadow mask characterized by having circular apertures at the mask center, and apertured at least in the mask periphery increasingly elongated radially outwardly as a function of distance from the center. The elongation of the apertures is effective to reduce or eliminate the distortion of the deposits on the mask periphery produced by diffrac­tion effects during photoscreening, and to form phosphor deposits compatible in size and shape with the electron beamlets. The screen of the tube according to the invention may have circular or near-circular phosphor deposits thereon. Tube types to which the invention can be applied include the conventional curved-screen/­curved-mask tube, and the substantially flat faceplate tube that has a foil shadow mask suspended in tension a predetermined distance from the screening surface. A method is also disclosed for use in the photo-fabri­cation of a faceplate for an ultra-high resolution color cathode ray tube.

In one embodiment, this current drawing means is connected to a voltage reference level VR1, and operates to draw an amount of current from whichever current node is at a voltage level which is closest to a predetermined constant plus this voltage reference level VR1. The amount of current drawn is controlled to cause this closest node voltage level to approach this predetermined constant plus VR1. In a preferred embodiment this current drawing means comprises a separate differential amplifier connected to each of the output current nodes.

Abstract: A domain-independent natural language interface for an existing entity-relationship database management system. Syntactically, it relies on an augmented phrase structure grammar which retains the convenience and efficiency of a semantic grammar while removing some of its ad hoc nature. More precisely, it is a syntactic domain-independent grammar augmented with semantic variables used by the parser to enforce the semantic correctness of a query; these semantic variables are only instantiated by a domain-dependent lexicon. Semantically, the interpretation of a query is in terms of general database navigation operations applied to domain-dependent parameters obtained from the lexicon. These operations apply to a virtual database, made of the actual database schema augmented with derived entity-sets. Navigation operations are eventually translated to acutal database queries.
