Abstract: La présente invention concerne un procédé et un dispositif de détection de signaux de données et de signalisation sur une voie téléphonique. Selon le procédé, on détecte des signaux de données et de signalisation chaque fois que, pendant une certaine durée dite temps d'activité préalable, le signal de la voie surveillée ne reste pas constamment inférieur à un certain niveau et présente, sur de petits intervalles de temps successifs, des valeurs maximales qui restent voisines les unes des autres. Le dispositif de détection pour sa part comporte des comparateurs à seuil de niveau et d'écarts commandant un détecteur suivi d'un circuit de maintien. L'invention s'applique notamment à la détection des signaux de signalisation en vue de neutraliser les dispositifs de suppression d'échos.

Abstract: "FIXED BED MULTIPLE ZONE FLUID-SOLIDS CONTACTING APPARATUS"                             ABSTRACT                A fluid-solids contacting apparatus which is useful in simultaneously contacting several different liquid streams with different parts of a fixed bed of solid material is disclosed.  The apparatus comprises an imperforate centerpipe mounted in an outer vessel with discoid layers of fluid distributor pans being suspended from the centerpipe and the vessel.  A fluid may be added or withdrawn at any layer through horizontal conduits leading to annular distribution rings mounted on the centerpipe, with smaller pipes branching radially from the distribution rings to the individual distributor pans.  Each distributor pan comprises an upper and lower horizontal particle retaining screen and two flat flow diversion plates which force the fluid to flow to a central mixing area between the plates and at which the smaller pipe connects with the distributor pans.  The distributor pans thereby serve to mix and redistribute fluids flowing vertically through the apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE A self-heating receptacle is provided herein comprising a vessel for food to be heated, and below the vessel, a container sealed by a lid.  The container contains two chemicals, e.g. quicklime and water, which are reagents for an exothermic reaction.  A pouch within the container holds one of the chemicals sealed from the other.  A flexible tearing filament secured to the pouch is for simultaneously opening both the pouch and the container, thereby to trigger the exothermic reaction to heat the food vessel.  The tearing filament is so connected to the pouch and is so arranged that, upon pulling the tearing filament, the tearing filament creates a line of tear across both the pouch and the lid.

Abstract: AN IMPROVED VARIABLE FLOW TURBINE                   Abstract of the Disclosure An improved variable flow turbine having a turbine housing constructed of a curved section and a volute section.  The curved section contains an inlet at one end and is connected to the volute section at the opposite end.  Located within the volute section is a turbine rotor having an outlet which is coaxially aligned with the central axis of the volute section.          Positioned at the inlet of the curved section is a control valve for regulating the flow of exhaust gases into the housing.          Extending inwardly from the control valve is a divider wall which divides the housing into inner and outer passages.  The divider wall is constructed such that the cross-sectional flow area of each the passages within the volute section decreases as they approach the turbine rotor.  This unique turbine arrangement enables a turbocharger to operate more efficiently over an engine's operating range.

Abstract: "ADAPTIVE DEMAND DEFROST CONTROL FOR A REFRIGERATOR"  ABSTRACT OF THE DISCLOSURE         An adaptive demand defrost control system controls the length of an interval between defrost operations in accordance with the number and duration of compartment door-openings, the duration of a previous defrost operation as corrected by the temperature of the evaporator prior to defrost, and the length of time the compressor has been energized.  A count is stored which is varied according to a decrementing schedule, with the decrementing schedule in turn being based upon a comparison of the corrected defrost duration with either a desired defrost duration or a range of desired defrost durations.  A defrost operation is initiated when the count reaches a predetermined value.  An alternative embodiment of the invention develops an indication of the ambient humidity and controls humidity-dependent apparatus in accordance with the indication.

Abstract: TITLE OF THE INVENTION:            A HIGH INTENSITY DISCHARGE LAMP IGNITION SYSTEM     ABSTRACT OF THE DISCLOSURE     A high intensity discharge (HID) lamp has an arc tube includ-ing a pair of main electrodes and at least one auxiliary electrode or probe, wherein a high frequency (HF) high vol-tage is applied to the probe for forming a high frequency (HF) ignition discharge for establishing a low frequency (LF) arc discharge between the main electrodes.  In this ignition sys-tem, the electrodes of the arc tube are arranged so that an LF discharge path and an HF discharge path are positioned in an X- or a Y-configuration in the arc tube for causing easy lamp ignition.  Also, to simplify the outer leads, it is desirable to mount the probe on one of the main electrodes by a dielec-tric member opposite another main electrode thereby to form a shorter gap between the probe and the other main electrodes than that between the main electrodes. The starting device of HID lamps has a high frequency - high voltage (HF-HV) genera-tor, the output of which is applied, directly or indirectly, to the probe.  Accordingly, sure ignition and hot-restrike can be achieved by applying through the outer leads a super-imposed voltage including the source voltage and the MF-HV.

Abstract: A management communication terminal is formed by integrating an electronic, raster scanning camera with a personal computer.the terminal has a keyboard winchester disk drive,a telecommunication controller,a cathode ray tube monitor, and a thermographic, raster image printer.Two such terminals define an office information system for the exchange of information produced at the keyboards and by the cameras. In each terminal, the coded data generated at the keyboard and the raster image data generated by the camera are temporarily stored in separate data buffers and from there are routed to the monitor, the printer and disk storage. The monitor and printer are able to display and print respectively, images created from the keyboard data, the camera data or a combination of the two. The camera data is compressed prior to storage and is reduced in resolution prior to application to the monitor. The telecommunication controller, when coupled to a transmission line, transfers keyboard and camera data directly between the disk memories associated with two terminals.

Abstract: ABSTRACT       The invention relates to a multiple pass optical rotary joint which can simultaneously transmit optical signals along two or more channels in either of two directions.  The joint uses a rotor and a stator to each of which is connected a plurality of optical fibers.  Within the joint reflecting mirrors are used to redirect off-axis optical signals onto the joint axis, with relative rotation occurring while the signals are on-axis.  A rotating member for each channel has a mirror for reflecting the on-axis signal portion off-axis to a receptor fiber.  Alignment between the rotating member and the receptor fiber, as well as drive for the rotating member, is provided by a pair of magnets of opposite polarity, one being secured to the rotating member and the other being secured to the rotor.          The magnetic interaction ensures synchronous rotation of the rotor and the rotating member.  Specific embodiments in which transmission losses can be minimized are also disclosed.
