Abstract: Arrangement (5) in a fuse (1) for projectile with explosive charge for changing over between direct and delayed ignition of the explosive charge. The arrangement comprises a movable contact member (6) which in an initial position short-circuits an electrical igniter (7) which is designed for direct ignition of the explosive charge. A locking member in the form of a pin (14) in an initial orientation of the projectile takes up a position in which the contact member can move under the influence of the accelerational forces effective on the projectile to a second position where the contact member is held by a detent device. With a second orientation of the projectile the pin, as a result of its own weight, drops down to a position where it prevents the contact member (6) moving from the said initial position.

Abstract: A process for the recovery of maleic anhydride contained as a by-product in a phthalic anhydride gaseous reactor effluent is described. This process consists of gas scrubbing in order to obtain an aqueous solution of the maleic acid and the other organic substances contained in the gas, including phthalic acid, concentration of this solution as maleic acid to a concentration of 25-35 % by weight by addition of a return stream to the solution and removal of the phthalic acid by crystallisation. The resultant solution, rich in maleic acid and depleted in phthalic acid, is then partially fed back into the gas scrubbing step (in order to promote the solubility of the phthalic acid and to enrich the solution of maleic acid thus obtained) and partially submitted to a treatment to recover the maleic anhydride by dehydration by means of azeotropic distillation with ortho-xylene. The resultant crude maleic anhydride is then purified by rectification in plate-type columns. An apparatus for the recovery of maleic anhydride is also described which includes a gas scrubbing section, a maleic acid dehydration section and a maleic anhydride purification section. <IMAGE>

Abstract: In access request control apparatus, more specifically apparatus for determining priority between a plurality of access requests in memory control apparatus, one access request from amongst a plurality of requests from channel processing devices (CHP) is seiected by a first priority determination circuit, whilst from amongst the selected CHP access request, acces requests from a plurality of central processing units and loop back access requests from a pipeline control circuit, one request is selected by a second priority determination circuit. 
     If a CHP access request is not selected by the second priority determination circuit, or is selected but nullified in the course of pipeline operations, the request is returned again to the first priority determination circuit. A higher priority is given to the request when it is returned to the first priority determination circuit. In addition, the priority algorithm of the second priority determination circuit takes into account the different kinds of operations involved in processing different access requests and thereby highly efficient memory access can be realized.

Abstract: Disclosed is a method and a means for creating a visual display of data from an input data set (22) in which the data are not fixed into display-acceptable format until the data are stored in a local memory (41) of the visual display. At least one of a plurality of sources (16, 18, 20, 34) of resource information is initially selected as required by the input data set. Control signals corresponding to the sources of resource information are thereafter embedded into the input data set to form an output data set (30). Subsequently, the selected sources of resource information and the output data set are applied to the local memory. They are concurrently taken from this local memory to produce a visual display. Fixation of the data into display acceptable format is thereby postponed until just prior to actual display to thereby provide a substantial increase in system flexibility.

Abstract: L'invention concerne un procédé de radicommunication bidirectionnelle entre des stations fixes et des stations mobiles permettant une utilisation efficace de canaux de radiocommunication disponibles. Toutes les stations fixes émettent dans une première voie radioélectrique des canaux de communication multiplexés et toutes les stations mobiles émettent dans une seconde voie radioélectrique des canaux de communication multipléxes, chaque paire de canaux de communication dans les première et seconde voies étant susceptible de transmettre une communication bidirectionelle entre l'une quelconque des stations fixes et l'une quelconque des stations mobiles. Il en résulte que la notion connue de motif cellulaire, et notamment de répartition de fréquences ou d'intervalles de temps entre cellules n'est plus mise en oeuvre selon l'invention, du moins en ce qui concerne l'acheminement des communications. Toutefois, cette notion de motif demeure conservée pour l'exploitation d'un canal dit sémaphore servant à la procédure d'etablissement des liasons. Lorsque les canaux sont multiplexes dans le temps, selon le procédé du type AMRT, deux voies numériques sont seulement utilizées. Lorsque les canaux sont multipléxes en fréquence, selon le procédé du type AMRF, seulement deux bandes de fréquence sont allouées aux radiocommunications. Application: Radiocommunications.

Abstract: The present invention relates to a burner which, in one mode can serve as a burner per se and in an alternate mode as a flue for removing waste gas from a combustion space.The burner has a body 1 which defines a passage 2forming in part a flow path for gases between two openings 3 and 4. The first opening serves either as inlet for receiving air for combustion with the fuel in a combustion chamber 16 in one mode of operation or as an outlet for discharging waste gas from the passage 2 in an alternate mode. The second opening 3 serves as an outlet for combustion products in the one mode of operation or as an inlet for receiving waste gas in the alternate mode. An assembly 5 injects fuel and air into the passage 2 and the fuel and air first mix in a nozzle 31 with the fuel being ignited by an electrode 47. The fuel is combusted in a pre-combustion chamber 32 before entering the main combustion chamber 16. The fuel is partially or fully pre-combusted irrespective of the mode in which the burner is operating to avoid prepurging with air or re-ignition between flue and firing cycles.

Abstract: In manufacturing a single crystal by means of the apparatus according to the invention, the crystal (20) is first pulled up at a relatively low speed V,. When the diameter D of the crystal reaches Do - ΔD, where Do is the target diameter and AD is a deviation allowance, the pull-up speed is changed to a second speed V 2  which is much higher than V,. When the diameter D reaches a peak value D, the pull-up speed is changed from V 2  to another speed V o  which is lower than V 2 . At the same time, PID control is performed based on Di and D, thereby controlling D so that it may become equal to Di. At the start of the PID control, D i  is set to be the peak value  D , and is then reduced by [K(D i - D o )], where 0 < K < 1. When D i  becomes substantially equal to Do, the target value Do is used to control the diameter D of the crystal.
