Ethylene glycol is prepared by a process in which ethylene oxide is extracted from an aqueous solution with near-critical or super-critical carbon dioxide. Thereafter an ethylene oxide-carbon dioxide-water mixture is contacted with a catalyst to form ethylene carbonate, which is then hydrolyzed to ethylene glycol in the presence of the same catalyst. The ethylene glycol is separated as product and...

PURPOSE: To enable formation of a scannogram emphasized within a predetermined layer where information exists laterally to the reflecting direction of an X-ray source, by positioning the X-ray source always on the side same as an object so that after the object moves, the X-ray source can irradiate the object from different directions and by providing with a operating means for combining detection...

A fiber guide includes a sleeve having a longitudinal slot therealong a first member, having a notch, is fixed in the sleeve with the notch substantially aligned with the slot. A second member, also having a notch, is rotatably disposed in the sleeve. Thus, a fiber can be positioned in the notches of the first and second members and secured therein by rotating the second member. The fiber can also...

A string-up system and apparatus, using a novel dual-slotted traverse guide, with preferential string up of a first yarn in the one slot, associated with transfer means to move a yarn, if desired, out of the first slot, so this yarn is strung up in the second slot.

A process for producing a porous, film-like or fibrous structure of an aromatic polyester, which comprises (1) forming a substantially non-oriented film-like or fibrous structure by melt-molding an aromatic polyester blend composed of (A) an aromatic polyester containing an aromatic dicarboxylic acid as a main acid component and an aliphatic diol and/or an alicyclic diol as a main glycol component...

La présente invention concerne une fixation arrière de ski alpin, destinée à maintenir l'extrémité arrière d'une chaussure sur le ski, comportant une glissière longitudinale 5 fixée sur la surface supérieure du ski 2, un corps 3 solidaire d'une embase 4 montée coulissante longitudinalement sur la glissière 5, un dispositif 6 de rappel élastique du corps 3 vers l'avant comportant un ressort de r...

The invention relates to a front jaw for a ski safety binding. According to the invention, a guide element 20', guided parallel above the ski, is provided in order to rest against the front side of the sole of the ski boot and a shoulder 20'a, in the form of a wedge, of the guide element 20' rests against an oblique surface 21'a of an intermediate piece 21' which serves for the pivoting of a compe...

The device (1) for clamping the reinforcement manufactured from a single wire (4) essentially comprises two jaws (10, 11) gripping the wires arranged at the beginning (41, 42) and at the end (43, 44) of the reinforcement. A sharp blade (13) cuts the wires and then, without unclamping the jaws, the latter bear against the core (7) for immobilising the wire (4) by virtue of the layer of raw rubber w...

The anti-friction plate is guided by vertical and longitudinal guidance apparatus allowing for a free lateral movement. The free lateral extent of plate 1 is limited by the play of the lateral ramps of an opening 22 which is laterally movable with the anti-friction plate 1 and in which a spur 26 affixed to jaw 6 penetrates. Spur 26 assures the recentering of plate 1 when the jaw 6 returns to the c...

To produce molten pig iron by melt-reduction of iron ores of various grain sizes containing a fraction A including grain sizes to which diameters of less than 0.2 mm correspond, by pre-reducing the ore by reducing gas, completely reducing the pre-reduced material and smelting it to molten pig iron in a melter gasifier, the pre-reduced ore fraction A is separated from a fraction B including larger ...

PURPOSE:To synthesize an oxide superconducting film free of impurities at a high rate by forming a substrate to be deposited with an oxide superconducting film with a material acting as an oxidation catalyst. CONSTITUTION:When an oxide superconducting film is synthesized, the substrate to be deposited with the film is formed with the material acting as an oxidation catalyst (at least one kind amon...
