Title: Procede de production de soufre elementaire a l'etat de gaz resistant a la diffusion de vue d'une reaction chimique.
Inventor: WILLIS H E JR
IPC: C01F11/10
Filed: 1984-10-16
Abstract: Du soufre est vaporisé (en 70) sous pression d'environ 0,1 MPa puis surchauffé à au moins 688 degrés C pendant son transit par un espace confiné tel qu'un conduit de transfert (81) débouche de l'espace confiné (71) dans une zone de réaction (24) sous forme de gaz cohérent qui résiste à la diffusion dans l'espace libre de la zone (24). Cette forme cohérente de soufre gazeux a une couleur violet rougeatre foncé. Du fait qu'il résiste à la diffusion dans ledit espace libre, ce soufre s'écoule au contact concentré de la surface de matière solide et y reste concentré en produisant une réaction gaz-solide dont la vitesse est grandement améliorée. Application à la récupération du soufre du gypse résiduaire, sous forme de SO2.

Abstract: METHOD AND APPARATUS FOR SUPPORTING TAPE      ALONG THE PATH OF A ROTATING HEAD          ABSTRACT          In rotating-head magnetic recording, the rotor carrying the magnetic transducer is enlarged in width so that the width of the rotor is much greater than the track width of the head.  The rotor is mounted in the middle of an air bearing mandrel around which magnetic tape is wrapped.  The wide rotor also provides an air bearing for the tape.  The air bearing for the rotor and mandrel is accomplished by forcing air through their cylindrical surfaces.  These cylindrical surfaces may be either a porous material or a nonporous material with holes through which the air may flow.          The wide air bearing rotor provides a very stable platform upon which the magnetic tape may rest while it is scanned by the rotating head.

Abstract: ENCAPSULATION BY UREA/FORMALDEHYDE POLYMERIZATION IN     PRESENCE OF POLYELECTROLYTE               Abstract of the Disclosure A process is disclosed for performing encapsulation, en masse, by an in situ polymerization reaction to yield capsule wall material.  The polymerization includes a reaction between urea and formaldehyde in an aqueous vehicle and the reaction is conducted in the presence of negatively-charged, carboxyl-substituted, linear aliphatic hydrocarbon polyelectrolyte material dissolved in the vehicle. Liquid-liquid phase separation is accomplished and maintained by increase in the molecular weight of the urea/formaldehyde reaction product without further dilution of the manufacturing vehicle.  The negatively-charged polyelectrolyte material is required and has an apparent effect of controlling or modifying the polymerization reaction. The disclosed encapsulation process permits manufacture of micro-capsules in concentrations of capsule to capsule manufacturing vehicle higher than previously possible.

Abstract: ABSTRACT OF THE DISCLOSURE   An electronic alarm timepiece particularly suitable as a watch which includes an oscillator and time counting circuitry and which also includes a recurrent alarm memory and a single alarm memory with a coincidence circuit switchable alternately to compare the setting in the recurrent alarm memory with the time counting circuit output and the setting of the single alarm memory with the time counting circuit output.  When coincidence of one of these memories with the time counting circuit is detected, the output coinci-dence signal actuates an alarm drive.  The coincidence signal is also able to actuate circuitry for reset of the single alarm memory if the coincidence signal has been produced by this memory.  A coincidence signal produced by the recurrent alarm memory does not lead to reset, and therefore, an alarm occurs each time the time counting circuitry comes into coincidence with the setting of the recurrent alarm memory.

Abstract: ABSTRACT OF DISCLOSURE     In an electrical  power generating installation which includes a plurality of turbine-generator sets, a parking bus is disclosed, which is provided with a potential regulated at a relatively low and constant frequency of the order of 1-2 Hz.          Switching and phase and frequency matching means are provided, which enable the same controlled variable frequency starting system used for start-up of the turbine-generator sets, to be used for gradually adjusting the rotational speed of a selected turbine-generator set to a point where phase and frequency may be matched with that of the parking bus, upon which the generator member of such set is electrically transferred to the bus.  By means of such arrangement, any number of turbine-generator sets may be connected in parallel to the parking bus, which there-upon effects a simultaneous, continued low speed rotation of the sets for cooling or other purposes.  The sophisticated, complex, and costly start-up system, is thus freed of any requi-rement for continuing rotation of the sets during the long cool-down period, whereby in typical installations but a single such start-up system is required.

Successive sections are spliced together with the projecting facer layer portion of one section overlying the projecting corrugated portion and the facing layer of another section, preferably with the adjacent portions of the corrugated layers of the two sections being in flute-enmeshing engagement. A conventional second web having a planar facer layer and a corrugated layer with transverse flutes may then be bonded in superimposed relation to the first web, thereby defining a third web having successive corrugated layers the flutes of which extend longitudinally and transversely of the third web, respectively.
