A reduction process and apparatus wherein the flow of the reducing fluid through the fixed bed of iron ore, oxidized pellet or the like to be reduced is reversed in direction so that the iron ore, oxidized pellet or the like, at any place in the bed, may be reduced uniformly.

PURPOSE:An apparatus for ending yarns, having internal yarn path holes mutually displaced on both sides from the center in the longitudinal direction and nozzles for forming swirling air streams on the wall surface of the yarn path holes, and capable of forming yarn joints having the same strength and thickness as those of other parts. CONSTITUTION:An apparatus for ending yarns by inserting two ya...

In the so-called splicing of yarns to form knot-free connections of two yarns (10, 20), it is essential that the yarn ends (11) terminate in pronounced fibre tufts, so that the fibres can loop closely round one another within the splice. In order to form such fibre tufts from the yarns (10, 20), the yarns are laid under slight tensile stress over at least one rotor (13; 16). Located on this rotor ...

PURPOSE:To obtain a sealed lead-acid battery having good and stabilized capacity by installing holes on the side of a container and inserting projections into the holes and pressing an electrode plate group by the projections. CONSTITUTION:In a sealed lead-acid battery in which electrolyte is held in positive and negative plates and separators, and free electrolyte is removed, threads are cut in a...

The present invention relates to a composite material comprising a porous lead alloy containing from 0.7 to 1.0% silver or 0.1 to 1.0% calcium or 0.7 to 1.0% silver and 0.1 to 1.0% calcium and having its pores filled by a resin such as epoxy resin. The product has utility as a battery electrode and as a sound absorbing material.

The application deals primarily with the guidance and positioning of a travelling automatic servicing device (16) relative to a plurality of operating stations (12), e.g. of a spinning machine, which are to be serviced thereby. Aspects of the communication of information between the device and the stations are also dealt with insofar as they are associated with the guidance and positioning feature...

A heel holder for release ski bindings having a hold-down device pivotally secured to a base plate slidably mounted on a guide rail fixedly secured to the upper surface of the ski. The hold-down device has an internal cam surface thereon which is engaged by a locking member urged into engagement with the cam surface by a release spring. The force generated by the release spring is adjustable to a ...

An electrically releasable safety ski binding in which a measuring system determines the load applied to a skier's leg during skiing and a release mechanism incorporating an electromechanical converter such as a solenoid acts on a clamp device securing the ski boot to the binding to release the ski boot when the aforementioned load reaches a dangerous level. To prevent the binding becoming inopera...

Fuel briquets containing binding agents and additives are obtained by briquetting of approximately 80 to 99% by weight of an essentially solid fuel, approximately 0.1 to 19% by weight of a natural or synthetic binding agent and approximately 0.1 to 10% by weight, calculated on a dry basis, of a cationic resin obtained by reacting polyamines with halohydrin.

A binding unit (1) is fastened to the ski and contains a piston (6) stressed by a spring (7). The body ends in a cover in which is accommodated a screw (21) on which are mounted two independent wings (15, 16) for the lateral holding of the foot and an intermediate bearing piece (51) for the longitudinal holding. The piston (6) bears on the wings and stresses them in the closed position. The wings ...

Under normal skiing conditions, two lateral arms of a jaw unit cooperate with the toe end of a ski boot in order to maintain the boot in the axis of the ski and are held in position with a force designated as the inherent stiffness of release. When an excessive twisting effort is exerted on the skier's leg, the arms both move in a transverse direction with respect to the ski in order to permit lat...

FIXATION DE SECURITE POUR RETENIR DE FACON DECLENCHABLE UNE CHAUSSURE SUR UN SKI, COMPRENANT D'UNE PART UNE PLAQUE PIVOTANTE 1 PAR RAPPORT A UN SKI AUTOUR D'UN AXE YY SENSIBLEMENT VERTICAL, ET D'AUTRE PART, DES PREMIERS ET DEUXIEMES MOYENS DE RETENUE DESTINES A RETENIR LA PARTIE AVANT ET ARRIERE DE LA CHAUSSURE, CARACTERISEE PAR LE FAIT QUE LES PREMIERS MOYENS DE RETENUE 4, 4, 4 SONT DISPOSES S...

A toe-abutment member providing safety ski boot release in the event of a backward-fall movement combined with a twisting movement of the skier's leg comprises a fixed locking member having an inclined ramp and an abutment body pivotally mounted on a cross-pin. The jaw unit for retaining the toe end of the ski boot is movably mounted within the abutment body and carries a transverse rod which is a...

Gearing mechanism providing for the automatic engagement and disengagement in a radial direction between successive gears in a gear train. A first gear, shown in the form of a rack gear, has a plurality of teeth traveling in a fixed path in space. Selectively meshing with the first gear is a second gear in the form of a pinion mounted upon a driving shaft, frictionally driven by the shaft, and hav...
