La conduite de décharge (13) du compresseur (11) présente des embranchements de sorte qu'une conduite (14a) est couplée au moteur à fluide rotatif (18) pour son entraînement, tandis que l'autre conduite (14b) fait circuler le réfrigérant jusqu'à une pompe de chaleur (21). L'écoulement de retour provenant du moteur à fluide (18) et l'écoulement de retour provenant de la pompe de chaleur (21) convergent au niveau de la conduite d'aspiration du compresseur (12). Le système peut fonctionner comme moteur thermique avec un arbre de prise de puissance (19b), ou bien il peut fonctionner comme un système de réfrigération actionné par la chaleur ambiante, suivant la taille des composants du système.

Abstract: An analog digital conversion is provided for two color difference signals, for example for a recording according to a timeplex method. The color difference signals are adjusted in their amplitude at the input of the analog digital converter such that the modulation range of the analog digital converter is always fully used independent of the original amplitude of the color difference signal. The amplitude is restored back to its original value after a digital to analog reconversion. This results in an improvement of the signal to noise ratio during the transmission. The amplification provided to the various signals can be controlled by comparator circuits comparing the signal level with a reference signal.

Abstract: A digital dynamic range converter of the forward control type for varying the dynamic range of an audio signal which is available in digital form and is constituted by a sequence of audio signal samples. In the multiplier device 5, each audio signal sample x(n) is multiplied by a control signal sample s(n) which is delivered by a digital control signal generator 7. This control signal generator 7 has applied to it unipolar signal samples x(n) which are derived by means of a transmission channel 9 from the audio signal samples x(n).In order to cause this dynamic range converter to respond rapidly to abrupt variations in the audio signal and to render it moreover universally usable, the control signal generator is provided with a digital peak-value detector 11 which converts the sequence of unipolar signal samples x(n) into a sequence of peak-value samples x(n). The latter are applied to an adjustable digital non-linear amplitude transformation circuit 12 which has an adjustable amplitude transmission characteristic curve determined by adjustment quantities R and a. It delivers the transformation samples sin) which are preferably converted in a digital low-pass filter into the control signal samples s(n) which are applied to the multiplier device.

Abstract: A system and method for scrambling and selectively descrambling television signals that are transmitted to subscribers' descramblers in a subscription television system. A working key signal is generated by processing an "initialization vector" signal in accordance with the DES algorithm upon the algorithm being keyed by either a common category key signal or a signal having a predetermined relationship to the common category key signal. A unique encryption keystream is generated by processing the initialization vector signal in accordance with the DES algorithm upon the algorithm being keyed by the working key signal. A television signal is scrambled in accordance with the unique encryption keystream to provide a scrambled television signal. A plurality of unique encrypted category key signals individually addressed to different selected subscribers' descramblers are generated by processing the initial common category key signal in accordance with the DES algorithm upon the algorithm being keyed by a plurality of different "unit key" signal unique to different selected descramblers. The scrambled television signal. the initialization vector signal, and the plurality of encrypted category key signals are broadcast to the descramblers. A corresponding tier of DES algorithms are employed at the descramblerto reproduce the encryption keystream; and the TV signal is descrambled in accordance therewith. Each descrambler has its unique unit key signal stored in a secure memory for use in reproducing the common category key signal when the descrambler is addressed by its unique encrypted category key signal.

Abstract: Coupleur optique et son procédé de production. Le taux de couplage du coupleur est insensible à la polarisation. Le coupleur optique ci-décrit se compose de fibres optiques à mode unique (12, 14). Chaque fibre optique présente une longueur de noyau presque exposé (20, 22) qui est fusionnée au noyau exposé de l'autre fibre optique tandis que les fibres sont maintenues juxtaposées et parallèles entre elles sans les tordre (24). En créant un coupleur à noyau fusionné à partir de fibres optiques à mode unique dans lesquelles les noyaux sont juxtaposés et parallèles entre eux, le taux de couplage du dispositif ainsi obtenu ne change pas avec les variations de la polarisation de la lumière traversant chaque fibre à mode unique, ce qui veut dire que le dispositif est insensible à la polarisation.

Abstract: A process for using an eddy current probe (25) having two connected coils (37, 39) to locate the edges (16a, 16b) of a support plate (13) which surrounds a tube (9) of a heat exchanger, comprises the steps of moving the eddy current probe (25) through the interior of the tube (9) in the vicinity of the plate (13). The rate of change of coil impedance is monitored as a function of the position of the coils (37, 39) along the longitudinal axis of the tube (91. When the rate of change of current flow through a coil attains its first maximum, the mid-plane of the coil is parallel to the bottom edge of the support plate. This process is particularly useful where heat exchanger tubes are selectively expanded to eliminate or reduce unwanted clearances between the tubes and the bores in the support plate through which they extend.
