Abstract: PRECIS DE LA DIVULGATION:     Procédé de raccordement d'un puits  à  une conduite d'écoulement formée de tubes d'acier, pour des profondeurs pouvant être supérieures  à  celles atteintes par des plongeurs, ce raccordement s'effectuant en partie au moyen d'une équipe d'intervention travaillant  à  l'intérieur d'une cloche de plongée.  Le procédé est caractérisé en ce que, préalablement à la mise en place de la tête de puits, on fixe à l'extrémité de la conduite un raccord que l'on verrouille sur une structure solidaire du puits, en ce que l'on descend et l'on oriente la cloche de plongée équipée d'une structure que l'on connecte au puits, rendant ainsi étanche la capacité formée par le puits, la structure et la cloche, et en ce que l'orientation donnée à la cloche et  à  la structure est choisie en fonction de l'orienta-tion du raccord de telle sorte, qu'ayant fixé sur le puits un sous-ensemble canalisant le tubage vers une vanne maîtresse, on connecte le sous-ensemble à un dispositif automatique de raccor-dement de canalisation solidaire de la structure et l'on raccorde automatiquement le dispositif au raccord de la conduite.

Abstract: INVENTION:         MEMBRANE HYDRO-METALLURGICAL EXTRACTION PROCESS            INVENTORS:         WIN-SOW HO                    LESTER T. C. LEE KANG-JEN LIU                     ABSTRACT OF THE DISCLOSURE A system utilizing membrane extraction is provided to recover metal values.  The system may be used to separate metal ions from an aqueous solution through the membrane by an organic liquid containing a chelating agent.  This invention also contem-plates the recovery of metal values from an organic phase, contain-ing the metal complexed with a chelating agent, by an aqueous phase using membrane extraction.  In the former case, the metal ion is passed through the membrane from the aqueous phase to the organic phase where it forms a complex with a chelating agent present in the organic phase.  In the latter case the metal is ex-tracted from the organic phase into the aqueous phase through the membrane.  In both cases a chelating exchange reaction is involved at the interface between the membrane and one of the two phases. This hydro-metallurgical process employs membranes with metal ion diffusivity in the range of about 10-5 to about 10-8 cm2/sec. and has advantages over conventional metal extractions and may be applied as the mechanism in pollutant removal and recovery as well as for metallurgical separations.

Abstract: WEDGE FEEDING MECHANISM FOR SHORT STROKE  DYNAMOELECTRIC MACHINE COIL AND WEDGE           INSERTING APPARATUS              ABSTRACT OF THE DISCLOSURE       Wedge feeding means for a short stoke dynamoelectric machine coil and wedge inserting apparatus of the type in which the slot wedges for an internally slotted dynamoelectric machine stator core member are inserted into the stator in a two stroke movement.  The wedge feeding mechanism includes front and rear wedge pushing elements which are moved by a hydraulic ram.  With each forward thrust of the hydraulic ram, the front pushing element inserts a group of wedges into the stator core member and the rear pushing element advances a second group of wedges to an intermediate position.  As the hydraulic ram is retracted, the front wedge pushing element cams along the underside of the wedges located at the intermediate position in returning to its initial position. With the next stroke of the hydraulic ram, the front pusher element engages the wedges at the intermediate position and the rear pusher element engages a new group of wedges to move both groups respectively to the stator and the inter-mediate position.

Abstract: FACSIMILE COMMUNICATION SYSTEM               ABSTRACT OF THE INVENTION        A facsimile communication system for compressing, transmitting and reproducing facsimile information is provided, wherein a transmitter includes a correlation detector.  When a first facsimile information scanned along a first scanning line has a low pattern density, the correlation detector determines by discrimination that at least one successive facsimile information, for example a second facsimile information scanned along a second scan-ning line adjacent to the first scanning line should be abridged.  Then, the transmitter compresses the first facsimile information and a third facsimile information contained in a third scanning line, and the compressed first and third facsimile informations are transmitted to a remote receiver.  The remote receiver also includes a correlation detector and the correlation detector deter-mines by discrimination that the compression-demodulated first facsimile information has a low pattern density.          Then, the remote receiver supplies the first facsimile information to a recording device when it scans a first scanning line and, further, repeated first facsimile information is supplied to at least one successive scan-ning line, for example, to a second scanning line.  There-after, the compression-demodulated third facsimile infor-mation is supplied to the recording device when it scans a third scanning line.

Abstract: RCA 68,828 Abstract The circuit includes a band selector which in one state controls the passage of a first band of frequencies (e.g. UHF signals) via a counter to a first input port of an Amplifier-Multiplexer (AMP/MUX) and which in another state controls the passage and amplification of a second band of frequencies (e.g. VHF signals) applied to a second input port of the AMP/MUX.          When the band selector is in the one state, the stages of the counter are activated and only signals in the first band are coupled through the counter and through the AMP/MUX to additional count down stages connected to the output(s) of the AMP/MUX.  In the other state, the stages of the counter are inactivated to prevent oscillations and feed through, and only signals in the second band are coupled through the AMP/MUX to the additional countdown stages.
