This invention relates to a double coupling for removably joining twin pipes, wherein the two connectors of the male piece engage in parallel bores in the female piece, and one of them cooperates with a bolt mechanism which ensures removable assembly of the two pieces. In a variant, the bolt is disposed between the two bores in order to cooperate with the two connectors.

Levers with double roller assemblies for positive cam mechanisms for controlling the heddle frames of weaving looms wherein each roller assembly comprises a rotating ring supported on a plurality of roller bearings retained relative thereto on a fixed support mounted to or on extension of the levers. The rings and supports are thus capable of penetrating between the cams of the weaving loom without modifying the axial dimensions of an assembly of such cams.

This invention relates to the shed forming devices in weaving looms wherein each of the retaining hooks is in the form of an element which is pivotable about a horizontal pin with each element provided with a tail portion which is subjected to the reaction of a compression spring so that the head portion thereof lies in a rest position above the toe of a corresponding mobile hook. When the mobile hook causes a retaining hook to pivot so that its nose or head is in an outer position with respect to the toe, an electromagnet of the device may be selectively activated to retain the retaining hook in this outer position to thereby prevent the mobile hook from being restrained by the retaining hook.

The present invention relates to fast-fit unions for removably joining pipes, wherein a tubular lock element loaded by a spring carries on its inner wall three teeth offset axially of the union with respect to one another, the central tooth being provided opposite the other two so that, to unlock the two elements of the union, two successive inward displacement maneuvers must be exerted on the lock element, consequently allowing the compressed fluid time in which to be evacuated to the atmosphere.

A non-return device for welding installations, of the kind comprising a movable valve arranged so as to free the passage of gas for the normal supply of the torch from a welding gas generator and, by contrast, to block said passage in the case of a back-pressure resulting from an explosion in the region of the torch burner, the said valve including for this purpose closure means co-operating with a seat under the effect of resilient return means, the valve including second closure means operating inversely to the first in such a manner that the displacement of said valve, under the effect of a sudden fall in pressure downstream of the device and against return means conveniently calibrated to this effect, ensures the automatic cut-off of the flow of gas through the assembly.

A process for assembling and an epicyclic reduction gear comprising a plurality of planets provided with outer toothings moveable rotatable about a shaft which are engaged with the toothings of, at least one adjacent gear ring. The shaft of the planets is mounted on a planet-holder so that it is adapted to move with respect to said planet-holder both radially and angularly in a plane perpendicular to the principal shaft of the reduction gear. The rotation shaft of each planet may be radially and angularly adjusted to a position where its outer toothing meshes with the toothing of the adjacent gear ring and may thereafter be secured in position.

In a jacquard system for forming the shed in a weaving machine, vertical reciprocating blades of griffe frames are controlled by concentric shafts driven by a single cam assembly connected to the input shaft driven by the drive shaft of the weaving machine. Each of the concentric shafts include radially extending levers which are connected to control the reciprocating movement of the blades.

A speed reducer of the cycloidal type for robots and other industrial manipulators which includes actuation fingers introduced in openings of toothed cams controlled by rotating eccentrics. Each actuation finger is formed by a roller bearing having an inner ring mounted about a pin with clearance to thereby allow self-centering of an outer ring of each roller bearing in its respective opening.

Heddle frames in which each upright includes an opening and a pair of spaced bearing surfaces and wherein each horizontal crosspiece includes a fixed and a movable jaw which extend outwardly therefrom and which jaws are engageable with the bearing surfaces upon adjustment of the movable jaws to thereby secure the horizontal crosspieces to the uprights.

This invention is directed to improved mobile hooks for the shed forming device of weaving looms wherein the mobile hooks are disposed at each of the ends of a funicular element. Each hook includes a web bordered by a vertical heel disposed in a slideway formed by grooves made in two opposing separating partitions with the web including a toe adapted to be hooked by the curved ends of a conventional blade element which is utilized to maintain the hooks in their uppermost elevated position. The hooks further include portions which are adapted to be gripped by conventional knives as the knives are moved vertically in reciprocating motion and also a push element adapted to displace the hook retaining blade against the core of an electromagnet which is used to selectively urge the retaining hook into engagement with the mobile hook when the electromagnet is activated.
