Abstract: "CONCENTRATOR SYSTEM WITH POLLING-RESPONSE MEANS   FOR DETECTING FAILURES TO STOP TARIFF CHARGES ON      LOCALLY ESTABLISHED INTRAOFFICE CALLS"                 ABSTRACT OF THE DISCLOSURE In a radio concentrator system, a master station and a terminal station cooperate with each to establish connections between remote subscriber terminals and a public switched network though radio message channels. An intraoffice call is set up between first and second subscriber terminals through the connections established in the terminal and master stations via the network. Upon establishment of such an intraoffice call, the terminal and master stations clear their connections and reestablishes local connections in the terminal station between the subscriber terminals. The master station transmits a polling signal at periodic intervals to the termination station, which responds to it by transmitting an acknowledgment signal as long as the local call is in progress. The master station detects if the acknowledgment signal is received in response to the polling signal. End-of-call indication is given to the network when the response is not received for a prescribed time interval to stop the tariff charges on the calling party.

Abstract: Abstract of the Disclosure:     In an encoding device for transforming a sequence of digital image signals into a sequence of transformed signals which is subjected to interframe predictive coding by the use of a subtracter and a local decoding loop, the subtracter supplies a block judgement circuit with a sequence of error signals divided into a sequence of blocks.  The block judgement circuit judges whether each block is a significant block or a less significant block to produce significant and less significant block signals, respectively.  The local decoding loop is selectively put into normal and specific modes in response to the significant and the less significant block signals, respectively.  In the normal mode, an inverse transform circuit and a local transform circuit are normally operated through a frame memory in the local decoding loop by producing a sequence of inverse transformed signals and a sequence of local decoded signal, respectively.  In the specific mode, the inverse transform and the local transform circuits are bypassed when the less significant block signal is produced by the block judgement circuit.          Alternatively, the frame memory may be controlled by a write-in controller supplied with the significant and the less significant block signals.  Similar operation is carried out in a decoding device.

Abstract: ABSTRACT OF THE DISCLOSURE           The dew point of the exhaust gas is firstly reduced to a value in the range of 60 - 65° C.  There-after the exhaust gas flows through a washing and con-densing apparatus. A part of  the prepurified  conden-sate is recirculated in a loop for carrying out said washing.  Thereafter the gas flows through a wet-deep bed filter apparatus.  The sprinkler apparatus belonging thereto is fed again  by a partly purified liquid.  A drying chamber follows the wet-deep bed filter apparatus. The gas is then finally purified in an electro-filter plant.  The condensate in the washing and condensing apparatus, to which also the washing liquid stemming from the sprinkler apparatus of the wet-deep-filter apparatus is added, is fed to a flotation plant.  This condensate-liquid mixture has an increased temperature such that a better working in the flotation plant is obtained.  The liquid flows thereafter through a bio-logical treatment plant, a repurification  apparatus, a sand filter apparatus  and finally through an ultra-filtration apparatus.  Between the individual liquid treatment apparatuses and plants, respectively, a part of the liquid is branched off and is fed in a closed loop fashion back to other apparatuses or plants in order to carry out purifying  or cleaning, respectively, functions thereat.  This allows an extremely economical operation of the entire apparatus.

Abstract: A process for expanding tobacco is provided which employs liquid carbon dioxide as the expansion agent. Tobacco is contacted with liquid carbon dioxide to thoroughly impregnate the tobacco with the liquid carbon dioxide. The carbon dioxide impregnated tobacco is maintained at a temperature no lower than -2 DEG  C. and under conditions of temperature and elevated pressure such that all or substantially all of the carbon dioxide which is in contact with the tobacco is in liquid form. After the impregnation has been completed, any excess liquid carbon dioxide which may be present with the tobacco may be removed from the tobacco. The elevated pressure is then reduced in order to convert the liquid carbon dioxide to solid carbon dioxide within the tobacco structure. The resulting solid carbon dioxide-containing tobacco is then subjected to conditions of temperature and pressure, preferably by rapid heating at atmospheric pressure, such that the solid carbon dioxide is vaporized and the tobacco is thereby expanded. Apparatus for carrying out the above described process is also provided.
