Title: Self-healing device of an annular link
Inventor: COZIC JEAN Y
IPC: H04L12/42
Filed: 1989-12-11
Abstract: The stations (S1to SN) are interconnected in series by a ring (A), and the system of the invention includes a spare ring (AS) interconnecting the stations in series, together with two self-healing circuits (CAM, CAV) in each station coupler (CS) between the two connectors (8, 9) of the coupler and its insertion relay (RI). The couplers are interconnected by cords (10; 11) each containing the ring (A), the spare ring (AS), and two detection links (12, 13). Each self-healing circuit includes a relay (6) and a relay control circuit (7) connected to a detection link whose other end is connected to ground in another self-healing circuit. Each relay (6) has fixed contacts (a1, a2, b1, b2), a first moving contact (C1) connected to the insertion relay (RI), and a second moving contact (C2). The second moving contacts (C2) of the two self-healing circuits (CAM, CAV) in the same coupler are interconnected by a spare link (L). In each self-healing circuit, the moving contacts co-operate with the fixed contacts so that in a rest position they interconnect the insertion relay (RI) with the ring (A) and the spare link (L) with the spare ring (AS), and in a working position they connect the insertion relay (RI) to the spare link (L).

Title: Method and apparatus for preprocessing and demodulating m-ary phase shift keyed (psk) signals
Inventor: LONG JAMES C
IPC: H04L27/233
Filed: 1990-02-09
Abstract: METHOD AND APPARATUS FOR PREPROCESSING AND demodulating M-ARY PHASE SHIFT KEYED (PSK) SIGNALS                 ABSTRACT OF THE DISCLOSURE       A method and apparatus is provided preprocessing and  for  demodulating M-ary  PSK signals wherein  the modulation  is  limited  to  phase  transitions  between adjacent phase transitions between adjacent phase states. The method of preprocessing comprises generating (112) harmonics  of  the  modulated  source  signal  prior  to demodulation thereby to expand the phase differential between adjacent phase states, and then demodulating (116) one of selected harmonic signals as if it were a simple two or four phase PSK signal.  The method of demodulating may be operative in a demodulator which comprises a phase splitter dividing a source signal into two or three paths with a preselected phase relationship among phases, one of the phases being delayed by nominally one bit period, one or two mixers or multipliers, each one of the mixers receiving as one input a representation of the delayed-phase component and as a second input a representation of one of the remaining phase components.   The signals provided  by  the  mixers  are  then  combined  in  a predetermined manner, if necessary, then compared by at least one two-level  comparator to provide a digital output.  Digital logic circuitry responds to the digital outputs of each of the comparators to map the digital outputs into a single digital bit stream of ones and zeroes.     27513Z.WP5

Title: Flexible conduit structure
Inventor: LAPLANTE PIERRE
IPC: F16L11/22
Filed: 1990-02-16
Abstract: ABSTRACT           An extruded conduit structure for conveying several different fluids is provided comprising a cluster of at least three tubes connected by webs extending between adjacent pairs, the tubes and webs being formed by simultaneous extrusion of a suitable plastic through a suitable die.  The outer surface of each of the webs is convexly curved in an arc that is substantial-ly tangential with the outer surfaces of the adjacent pair of tubes.  The inner surface of each of the webs is flat relative to the outer surface and forms a cord of such arc whereby each of the webs will be of minimum thickness along each of its junctures with the adjacent webs.  This construction substantially eliminates any concave surfaces on the exterior of the conduit within which foreign matter may collect and, because of the thinner wall sec-tions at the juncture of the webs with the adjacent tubes, the webs can be easily stripped along the tubes to expose the tube ends for connection to the apparatus, such as a dental hand piece to which they are to be connected.

Title: Device for reducing the redundancy in blocks of digital video data in dct encoding
IPC: H04N7/30
Filed: 1990-03-21
Abstract: ABSTRACT           A converter processes a digital video signal according to a known redundancy reducing algorithm executed on successive block for each frame or field, generating a transformed signal which is applied to a quantizer adapted to generate a quantized signal at preset transition levels on opposed sides of the zero, including the zero (...,-3,-2,-1 0, 1, 2, 3,...).  The quantized signal is processed by a processor, adapted to determine the block length and the consecutive zero sequences along a preset scanning order, and to output a symbolic signal constituted by symbols indicating the quanti-zation levels of the non null data, the zero sequences and a symbol indicating the block end.  The symbolic signal is applied to a variable length VLC encoder, adapted to encode data according to a preset designation law for generating a signal which is applied to a transmission buffer.  According to the invention, said quantized signal,  generated by the quantizer, further includes two ambiguous levels (x1 and x-1) at input values falling within respective preset intermediate ranges respectively between the zero level and the first positive level and between the zero level and the first negative level;  the processor transforms each of the ambi-guous levels respectively in a first positive level and first negative level if the preceding and subsequent input values are both non null and non ambiguous, and transforms the ambiguous level in zero level in all the other cases.

Title: Mixed refrigerant/expander process for the recovery of c_+ hydrocarbons
IPC: C07C7/04
Filed: 1990-05-08
Abstract: ABSTRACT   The present invention is an energy efficient process for the recovery and purification of C3+ hydrocarbons from a high pressure natural gas or refinery/petrochemical feed gas containing C3+ hydrocarbons and light gases.  In the process, the high pressure feed gas is initially cooled by heat exchange with a multi-component refrigerant fluid circulating in a closed-loop cycle thereby condensing a large portion of the C3+ hydrocarbons.  The non-condensed, remaining gas is work expanded to an intermediate pressure thus providing refrigeration for condensing the remaining C3+ hydrocarbons.  The condensed C3+ hydrocarbon liquid streams are combined and are further purified by distillation in an integrated distillation column.  Optionally, refrigeration for refluxing the integrated distillation column can be provided by the mixed refrigerant cycle.
