Inventor: RILEY NORMAN
IPC: C07C231/00
Filed: 1978-12-13
Abstract: N-Formylanilido aromatic compounds containing at least two electron-withdrawing substituents in the benzene ring are obtained by reacting together equimolecular quantities of a formanilide and an aromatic halogen compound in the presence of a diluent and an acid-binding agent at a reaction temperature below that which causes decarbonylation. The corresponding anilido aromatic compounds are obtained by conducting the process at a reaction temperature above the temperature of decarbonylation or by heating the N-formylanilido aromatic compounds above their temperature of decarbonylation.

Abstract: Air is circulated through flexible disk stack 12 mounted on shaft 16 by centrifugal action which draws air into the centre of the stack via filter 28, controller 26 and plenum chamber 24. Controller 26 provides primary and secondary air flow paths in parallel into chamber 24, the primary and secondary paths being open and closed respectively at start of a disk access operation. To access, transducer head 20 is positioned to cause a partial split between two selected adjacent disks, and the primary path is closed, which develops a high vacuum in chamber 24 and causes the partial split to become a full access opening. The secondary path includes a valve automatically responsive to pressure in the chamber 24 to supply, after short delay, a throttled flow of gas into the chamber 24, to reduce the vacuum to a level at which the full access opening is stable.

Abstract: Quaternary modulation system for digital data transmission applied to a Quaternary Phase Shift Keying (QPSK) system that corresponds to the sum of two bi-phase carriers duly phase-shifted, adapted to the transmission of digital data previously subdivided into two binary signal trains, in which the spurious amplitude modulation is compensated for, at least in part, by altering the amplitude of that component of the quaternary phase carrier which does not change its state in correspondence with the phase transitions of the modulated signal.

Abstract: The invention relates to a device for admitting additional air or gas into the idling well 20 of a carburettor when the throttle 14 is in the vicinity of the progression 24 and idling 25 ports in the partial opening position. A circuit parallel to the air calibrator 21 and terminating, for example, at a hollow adjusting screw 30 is controlled by an adjusting member 50, such as a valve, the movable shutter of which is actuated, for example, by a linkage 55 coupled to a throttle on the one hand and to a differential pressure gauge on the other hand or by means of a stepping motor 58 coupled to a pulse generator 59 controlled by a microprocessor receiving information from various sensors C1 to Cn. This device makes it possible positively to control the relative vacuum in the idling well and consequently the airflow through the calibrator and thus the flow of fuel sucked up by the nozzle, in order to keep substantially constant the richness of the mixture supplied to the engine during transitions between idling and normal running. <IMAGE>

Abstract: A mass transfer device of the type used, e.g., for blood dialysis is made by winding on a mandrel (20) a series of fiber strands (24), each of which consists of a solid fiber (26) and one or more hollowfibers (22), the solid fiber being at least as large, and preferably substantially larger, in diameter than the hollow fiber. As the strands are wound on the mandrel they are temporarily anchored at spaced locations along the mandrel by beads of a liquid pre-potting compound which eventually harden into solid anchor plates (32). When the winding is complete, the mandrel is cut at each anchor plate to form individual temporary cartridges which can withstand the handling required in washing and drying. After each individual cartridge is final-potted, the anchor plates (32) are discarded. and the final potting is cut in a conventional manner to form manifold surfaces at each end of the cartridge. A deburring treatment is then applied to the manifold surface at each end of the cartridge to smooth out any microscopic irregularities of the manifold surface which can cause thrombogenesis.
