摘要:
The method for decolorizing fibers includes applying a decolorizing composition according to the invention to dyed fibers and allowing the composition to act on the fibers for a sufficient time to remove dyed color from the dyed fibers. The decolorizing composition for fibers dyed with an oxidation hair dye composition and/or direct-dyeing hair dye compounds contains a combination of one or more .alpha.-oxo-carboxylic acids and/or physiologically compatible .alpha.-oxocarboxylic acid salts with at least one reductone, or with at least one reductone and at least one thiol compound, or with at least one reductone and at least one sulfite compound, or with at least one reductone and at least one thiol compound and at least one sulfite compound. A multi-part kit for repeatedly dyeing and subsequently decolorizing fibers, especially human hair, contains both a dye composition for dyeing the fibers and the above-described composition for reductive decolorizing of the dyed fibers.

摘要:
An emergency release device for the strap of a toe clip for a bicycle pedal. The release device comprises a release member pivotally mounted on free end of the toe clip. One end of the strap is attached to the release member and the other passes through an aperture in a buckle associated with the release member. In one embodiment the buckle consists of a buckle lever, and a passageway is provided through the release member itself. In another embodiment the release member is releasable attached to the buckle. The release member includes a latching member and in response to the pivoting of the rider's foot in the pedal the force exerted on the strap displaces the latching member to its inoperative position. The release member pivots relative to the toe clip thereby permitting the rocking of the buckle lever in the first embodiment or the release of the buckle through a hooking member in the other embodiment. In either case the binding force around the rider's foot is relaxed without the rider having to loosen the buckle by hand.

A metal obturating element is capable of being resistance-welded to the outer side of an edge of a hole of a metal wall of a pressurized gas reservoir of a gas generator, including on a first side, a portion dimensioned for covering the hole and having an end intended to be inserted into the hole, and a portion for connecting the portion to the peripheral edge, having a surface tilted rearwards relatively to the end and around the portion, this surface intended to be welded to the outer side of the edge of the hole. The element is formed with a deep-drawn part. The tilted surface forms around the central portion an angle greater than or equal to 50° and less than or equal to 80° relatively to the axis. The part includes in a second side located opposite to the first side another surface tilted rearwards relatively to the end and this by at least one angle greater than or equal to 10° and less than or equal to 80° relatively to the axis.

The tank comprises a variable volume chamber containing a liquid and defined by a wall; and a piston suitable for moving in the tank under thrust from powder gas at a temperature much higher than that of the liquid in order to decrease the volume of the chamber. The tank also comprises a deformable elastomer membrane pressed against a face of the piston outside the chamber, the membrane being suitable for thermally protecting the wall and for providing sealing between the piston and the wall.
