A telephone exchange conference circuit for three-party conferences, receives the PCM bytes from the conferees in a FIFO store (4), and checks the bytes in a processor (1) to find the one for the loudest outgoing speech. This is then sent to another FIFO store (5) for transmission to the other conferees. This loudest speech sample is sent to all conferees other than the one which originated that s...

PURPOSE:To carry out methane fermenting treatment efficiently by providing a membrane separating means with surface of moving membrane in a fermenting tank and draining separated penetrating liquid outside the tank. CONSTITUTION:Liquid to be treated being introduced into a draft tube 12 through a line 14 is flowed up through the draft tube 12 and circulated in a tank 10 by driving an agitating pum...

L'invention concerne une poche pour excrétions à jeter dans les cuvettes de toilettes, comportant une couche extérieure soluble dans l'eau 11 en alcool de polyvinyle, et une couche intérieure pratiquement insoluble 12 en chlorure de polyvinylidène. Cette poche est agencée pour être fabriquée de manière simple et peu coûteuse, sans qu'il en résulte d'inconvénients à l'utilisation.
