Abstract: L'invention concerne un procédé de fabrication de méthane, par réaction de l'hydrogène avec le monoxyde de carbone en présence d'un catalyseur contenant du ruthénium. Ce procédé est caractérisé en ce que l'on fait circuler l'hydrogène, le monoxyde de carbone et une phase liquide aqueuse à travers un lit fixe de catalyseur renfermant du ruthénium sur support, à une température comprise entre 200 et 320.degree.C, à une pression totale comprise entre 1 et 15 MPa et à une pression partielle du mélange (CO + H2) comprise entre 0,1 et 2 MPa, la phase liquide aqueuse circulant d'une façon exempte de ruissellement et à un débit maintenant le catalyseur baigné dans ladite phase liquide, en ce que l'on sépare la phase gazeuse résultante de la phase liquide aqueuse résultante, en ce qu'on fait passer la phase liquide aqueuse à travers un échangeur de chaleur externe à la zone de réaction, pour refroidir ladite phase aqueuse, et en ce qu'on recycle la phase aqueuse refroidie, au moins la majeure partie de la chaleur dégagée par la réaction étant éliminée dans ledit échangeur de chaleur par l'intermédiaire de la phase aqueuse circulante. L'invention s'avère particulièrement utile pour effectuer en une seule passe des conversions élevées du mélange de synthèse hydrogène-monoxyde de carbone.

Abstract: ABSTRACT OF THE DISCLOSURE:           The production of a tubular container is effected by rolling and lap-welding a multi-ply foil to form a cylin-drical tube body, the arrangement of a collar which par-tially closes this tube body at the top, and the production of a head piece of plastics material, which on the one hand connects the tube body to the collar and on the other hand forms the top closure of the tube.  The collar has a simple basic form before working and is brought by the working into a form in which its cut edges can be covered by plastics material flowing thereover, this shaping requiring no addi-tional working operation, but being effected by the forces set up during the moulding process of the plastics material.          Further by the shaping of the collar, the spacing between the collar and the tube body is reduced, thereby further improving protection against diffusion.

Abstract: ABSTRACT        A heat exchanger plate block (10) is comprised of a stack of consecutive, spaced, parallel rectangu-lar plates (11) mounted within an enclosing frame.          The frame has end walls (12) parallel to the plates and corner posts (14) extending between and joining corners of the end walls.  Resilient spacers (26) are included between the plates to render the stack of plates elastically compressible as a unit in a direc-tion normal to the planes of the plates.  Resilient corner spacers (23) are provided to space corners (34) of the plates from adjacent corner posts to accom-modate growth of the plates due to thermal expansion in their planes.  The plates of the plate stack hence float within resilient fixtures which accommodate thermal expansion parallel to and normal to the planes of the plates.

Abstract: CIRCUIT FOR SELECTIVELY EXCITING ONE OF A PAIR OF LIGHT EMITTING DIODES            Abstract A circuit for selectively lighting one of a pair of light-emitting diodes (LEDs) arranged in a parallel, back-to-back, circuit configuration also known as an anti-parallel circuit configuration.  One side of the configuration is connected with ground connecting means through a first photon-emitting device which device is optically coupled to a first photon-responsive device connected between the other side of the configuration and a current source.  The other side of the configuration is also connected with a ground connecting means through a second photon-emitting device which device is optically coupled to a second photon-responsive device connected between the first side of the configuration and the current source.  Shunting means having a resistance value larger than the value of the first or second photon-responsive device when either is conducting is connected in parallel across the first photon-responsive device such that when ground is connected to one side of the configuration current flows from the source of current through the shunting means and the first photon-emitting device causing the first photon-emitting device to emit photons which impinge on the first photon-responsive device driving it into conduction to bypass the shunting means thereby allowing sufficient current to flow through and ignite one of the pair of LEDs.  Similarly, when ground is connected to the other side of the configuration current flows from the current source through the shunting means and the second photon-emitting device causing it to emit photons which impinge on the second photon-responsive device driving it into conduction to bypass the shunting means such that current flows through and ignites the other of the pair of LEDs.  The circuit can also be used in a switching matrix.
