Abstract: The invention relates to a method of characterizing and of quantifying carbon from a superficial deposit, wherein a sample of the deposit is subjected to heating in an inert atmosphere, the sample residue is subjected to heating in an oxidizing atmosphere, and quantities of HC, CO and CO2 released during heating, from which standard parameters TOC and MinC, and a ratio between mineral carbon and total carbon of the sample are determined, are measured. If the ratio is non-zero, the organic carbon content is equal to the sum of TOC and of a percentage of TOC ranging between 4 and 12%, and the mineral carbon content is equal to MinC minus this percentage of TOC. If the ratio is zero, the mineral carbon content is zero and the organic carbon content is equal to the sum of TOC and MinC.

Abstract: A quarter-turn fastening device for fastening a part to a support comprising comprises: a head carrying the part and intended to rest on a first face of the support; and a holding foot connected to the head and extending along a main axis, the holding foot configured to penetrate axially into an opening of the support, thereby placing the fastening device in an insertion position. The holding foot comprises at least one flexible retaining tab for resting on a second face of the support when the fastening device is moved angularly from the insertion position to a locking position. The flexible tab carries a lug to fill the space between the holding foot and an edge of the opening and thus refocus the fastening device in the opening when the fastening device is moved angularly from the insertion position to the locking position.

Abstract: A device for adjusting an elevation of a piece includes a body intended to be secured to a support and comprising a central cylinder provided with an internal thread, and a pin having, over one section of its length, an external thread, and a first end for bearing the piece. The pin and the body are connected to each other through their respective threads, and the pin can, when rotated, move along a longitudinal axis to adjust the elevation of its first end. The body comprises a head with a side window and the pin has, over one section of its length, peripheral notches opposite the side window of the body. The adjustment device also includes a lock placed in the side window of the body, the lock cooperating with the notches of the pin to index the movement thereof.

Abstract: A spacing device with angular adjustment for filling the space separating a first support from a second support arranged facing the first support includes an attachment part, a spacing part, a drive ring, and a support ring. The attachment part is intended to be rigidly connected to the first support. The spacing part has a spherical tipped support end. The drive ring include an attachment system and is housed in the spacing part and coupled to the spacing part. The attachment part and the spacing part are assembled together, and the support ring is held against the spacing part and retained by the attachment device of the drive ring. The support ring has a face with a spherical cap.

Abstract: A separating device includes an attachment part and a separating part. The attachment part and the separating part are assembled together and can move relative to one another in an axial direction in order to adjust the separating device. The separating device comprises a driving ring, accommodated in the separating part and capable of being rotated by a tool, the driving ring comprising at least one first coupling means capable of engaging with a second coupling means of the separating part, forming a claw system, for selectively coupling and uncoupling the driving ring and the separating part.

Abstract: An attachment device for attaching to a generally channel-section rail having rims forming a channel is provided. The device comprises a latch for inserting into the inside of the channel and for being retained therein by the rims of the rail, and a locking member for locking the latch in the rail. The locking member comprises a rotary shaft secured to the latch and extending axially through a bearing plats for resting on the top of the channel. The locking member also includes a cam adapted to move the bearing plate axially relative to the rotary shaft when the rotary shaft is turned in one direction or the other. The bearing plate comes closer to the latch when the rotary shaft is turned in one direction of rotation and the bearing plate moves away from the latch when the rotary shaft is burned in the opposite direction.

Abstract: A buffer device with a self-adjustable stop comprises a buffer head (5) in the form of a shank presenting along its length a flat and touching ribs or grooves (6), and a socket (8) into which the buffer head in the form of a shank can be driven axially, serration by serration. The device further comprises an annular ring (7) inserted axially in an axial bore in said socket and presenting a bottom edge defining a thrust ramp. The ring has an inner surface presenting a smooth strip and an adjacent serrated strip such that actuating the ring by turning it causes the buffer head to be raised and its axial position to be blocked.
