Title: Method for producing ultrapure oxygen
Inventor: NAGAMURA TAKASHI
IPC: F25J3/04
Filed: 1989-12-01
Abstract: This method comprises the following stages. Liquid oxygen containing impurities in trace form is conducted towards a first fractionating tower 1 where the fractionation is performed, very pure oxygen is produced in the liquid state at a reboiler situated in the tank of the said first fractionating tower 1, or at an intermediate point between the said reboiler and a fractionating section of the said fractionation tower 1, and the very pure oxygen is conducted towards a fractionating section of a second fractionating tower 6 where it undergoes fractionation. Ultrapure oxygen is thus obtained in the upper part of the fractionating section or in a position adjoining a condenser 6b provided in the second fractionating tower 6. Application to the production of low-priced, ultrapure oxygen.

Patent FR-2670350-A1 (FR)
Inventor: DANIEL BILLET
IPC: G01V1/22
Filed: 1990-12-11
Abstract: The invention relates to linear acoustic antennas formed of an assembly of sections which are butt-end connected and towed by a tractor ship. It comprises minimizing the equipments directly connected to hydrophones (301) in order to obtain processing and digitizing modules (103) distributed regularly inside the section. These modules are supplied with alternating current and with synchronization signals from a synchronization module (204) situated in the semi-junction downstream of the section. They transmit their signals to a first multiplexor (203) which gathers them in order to form a packet sent to a second multiplexor (209) which places such packet next to those corresponding to the downstream sections of the antenna on the high flowrate connection connecting the downstream junction to the upstream junction. It allows to obtain a section whose linear weight is much more constant and which may be repaired more easily.

Title: Telomerisation of conjugated diene with sugar (derivs.) - by a reaction in aq. soln. and in the presence of a palladium@ catalyst and a ligand
Inventor: ISABELLE PENNEQUIN
IPC: C07H15/10
Filed: 1992-07-01
Abstract: A process is claimed for the telomerisation of conjugated dienes with polyols in the presence of a Pd catalyst. The diene is reacted with a conc. aq. soln. of the polyol (10-90%), the Pd catalyst being associated with a ligand which aids solubility in the aq. medium. Pref., the polyol is a non-reducing mono-, di- or tri- saccharide - a non-reducing sugar, more pref. sucrose, trichalose or a 1-12C alkyl glucoside. Alternatively it may be a polyol resulting from hydrogenation of a sugar e.g. sorbitol, xylitol, erythrite, maltitol, lactitol and palatinate, or a prod. resulting from dehydration of a hydrogenated sugar i.e. sorbitan or isosorbitan. The di-ene component is a 4-10C conjugated diene - more pref. butadiene, isoprene or piperylene. The Pd catalyst is a Pd(II) salt - associated with a water sol. phosphine - or a Pd(O) deriv. associated with a non-coordinating ligand and a water sol. phosphine: the phosphine is more pref. triphenyl-phosphine trisulphonate (Na salt) (TPPTS). ADVANTAGE - The process avoids loss of dienes by dimerisation or telomerisation with the solvent, which were disadvantages of former processes, using a sec. or tert. alcohol as solvent. The new process uses water as the solvent. Comparable amts. of catalyst are used compared with previous techniques.

Title: Prodn. of lid, esp. for drink or preserve cans - by heat-sealing plastic coating on ring-pull opening tab to lacquered top of can using heated jaws
Inventor: JEAN-FRANCOIS JOUILLART
IPC: B32B27/08
Filed: 1992-07-03
Abstract: A process is claimed for prodn. of an easily openable lid by heat-sealing a metal panel, having an external protective coating, with a metal opening tab, having an internal heat-sealable coating, to form a connection. The panel includes a peripheral region forming a seal with a container body and a central, at least partly detachable, movable region defined by a line of weakness. The tab includes a gripping ring, a hinged fixing region and a supporting neck adjacent to the line of weakness. The novel features are that: (a) the heat-sealable coating layer is of thermoplastic having thickness 20-80 microns, at least the outer part of which is heat-sealable; (b) the protective coating is of polymeric material thinner than the heat-sealable layer; and (c) the two layers are heat-sealed using heated jaw (pref. at 200-350 deg.) for sufficient time to give an elastic connection between the layers. USE/ADVANTAGE - The lids are for food containers, esp. for cans contg. preserves or drinks. Heat-sealing is effected rapidly and reproducibly, with very few rejects. The tab is firmly fixed without using a rivet. A wide variety of materials (including many conventional components) can be used, with the organic material content minimised to facilitate recycling.
