A cryogenic rectification system having high recovery of both higher purity and lower purity oxygen which employs a side column having a bottom reboiler wherein feed air is partially condensed and the feed air vapor remaining after the partial condensation is turboexpanded prior to rectification.

The present invention relates primarily to a system for transfer of data in a network, in particular in connection with games, lotteries, and the like, the said system comprising substantially one main administration server, and for the purpose of providing a system which may easily be controlled from one single contractor yet still allow access for users or players at a global level, it is accord...

A process for purifying fluoropolymers by contacting them at temperatures above 140 DEG C. with a liquid perfluorinated cycloalkane. The resulting polymers are particularly useful where polymers with reduced impurities are desirable, such as in medical devices and in parts for the semiconductor manufacturing industry. The liquid perfluorinated cycloalkanes improve the adhesion of fluoropolymer to...

A thin, tacky, non-pourable film of incompatible in situ-expandable thermoplastic particles and thermosettable matrix resin that contains an essentially uniform density and thickness across the breadth of the film. The in situ-expandable mass is not pourable yet can be easily dispensed in a uniform manner within a mold and thereafter expanded to the dimensions of the mold. Composites and reinforce...

The extremely low temperature cold accumulating material for use in refrigerators, for example, comprises particles containing at least one kind of rare earth element selected from a group consisting of Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, and Yb. The proportion of particles each having a particle size of 0.01 to 3 mm is 70 % or greater by weight with respect to the whole particl...

A long-life polymeric packaging containing a fruit and/or vegetable beverage, and consisting of a single layer of methyl acrylate-acrylonitrile-butadiene terpolymer, is disclosed. A method for controlling the spoilage of fruit and/or vegetable beverages in a polymeric packaging, characterised in that said packaging consists of a single layer of methyl acrylate-acrylonitrile-butadiene terpolymer, i...

L'invention concerne un procédé pour transformer à la surface de la peau une énergie lumineuse d'un rayonnement laser en énergie thermique utilisant une composition comprenant au moins un chromophore, caractérisé en ce que (1) on applique sur ladite surface de la peau une composition comprenant, dans un support physiologiquement acceptable, au moins un chromophore, cette composition et son épai...

L'invention a pour objet un copolymère éthylène/ester (méth) acrylique de polyalkylèneglycol (éther) comprenant les motifs monomères suivants:
(i) de 99 à 50% en poids d'éthylène;
(ii) de 1 à 50% en poids d'un monomère de formule I:
CH2 = C (R1 ) -COO- [Cm H2m -O] n -H
dans laquelle R1 est H ou CH3 ; m est un entier qui vaut 2, 3 ou 4; n est un réel compris entre 2 et 25; et

A method which is used for optically detecting moving objects method comprises an image recording unit 1, a computing unit 2 with a memory 4, and a signal display 5. The computing unit compares an image recorded by the image recording unit with a reference image in relation to the measured variables: image signal variation, displacement and texture. For determining the comparison values the chrono...

The instrument panel includes two light sources (20,22) which are fed via a ganged pair (55) of variable resistances (53, 54), so that the combined output is constant at all settings for any particular setting of the variable resistance (50) in the common supply line (Vcc), which determines the overall illumination intensity. Optionally, similar control is effected by an electronic master unit. Th...

The motorised vehicle has two axles (3,4) mounted so they can pivot relative to the chassis (5) of the vehicle. Each axle has a motor unit (1A,1B,2A,2B) that can be turned relative to the axle, but are held parallel to each other. The motor units are independently controlled. The motor units are controlled by a feedback controller (8) responding to detectors (13A,23B) that measure the angle of the...
