Abstract: The invention relates to a so-called stabilization method, consisting of completing the filling of traveling egg trays. In each of the successive trays, eggs taken from an available egg reservoir are deposited in empty locations. This reservoir is made up of egg receiving cells that are movable along rows of cells in series. Depending on a filling state of the tray being treated identifying the distribution of the empty locations relative to the full locations, the reservoir is automatically configured in a configuration of egg-bearing cells complementary to said filling state of the tray in progress, so as to next transfer eggs between the reservoir and the tray in progress by correspondence between empty locations and full locations in the tray and the presence or absence of an egg-bearing cell in the reservoir.

Abstract: The invention relates to a so-called stabilization method, consisting of completing the filling of traveling egg trays (8). In each of the successive trays, eggs taken from an available egg reservoir (16) are deposited in empty locations. This reservoir is made up of egg receiving cells that are movable along rows of cells in series. Depending on a filling state of the tray being treated identifying the distribution of the empty locations relative to the full locations, the reservoir is automatically configured in a configuration of egg-bearing cells complementary to said filling state of the tray in progress, so as to next transfer eggs between the reservoir and the tray in progress by correspondence between empty locations and full locations in the tray and the presence or absence of an egg-bearing cell in the reservoir.

Abstract: A part-processing machine having, in series, consecutive parts on a belt (2) moving same along a main conveying line. Selectively identified non-compliant parts are removed from the conveying line, into a transfer device (1) by pickup tools (8) supported on the periphery of a rotating drum (6) mounted transversely to the conveying line and arranged to rotate about itself so as to pass over the belt, enabling the non-compliant parts to be picked up by the pickup tools and released once the parts have been transported away from the conveying line. The pickup tools have pneumatic gripping heads, more particularly for example suction cups. The pneumatic gripping heads are depressurized relative to the surrounding air by a low-pressure chamber provided inside the drum, to which each head is connected by a tube inside a tool support arm.

Abstract: Tyre and rubber composition for tyre, based on at least one isoprene elastomer (for example natural rubber), an inorganic filler as reinforcing filler (for example silica) and a coupling system which provides the bonding between the said reinforcing inorganic filler and the isoprene elastomer, the said coupling system comprising, in combination: as first coupling agent, a silane sulphide compound; as second coupling agent, an at least bifunctional organosilicon compound (for example an organosilane or an organosiloxane) which can be grafted to the elastomer by means of an azodicarbonyl functional group (—CO—N?N—CO—).

The process allows a high degree of grafting of the polyether to the polymer chains. Also disclosed is a reinforced rubber composition, especially intended for the manufacture of tires, comprising such a diene block copolymer which is intended to interact with the reinforcing filler. Such a rubber composition has improved hysteresis properties in the vulcanized state, while retaining satisfactory processing properties in the non-vulcanized state.

Abstract: The invention relates to a system applicable to an installation for candling eggs, to determine the presence of fertilized eggs in the cells of the egg crate grid moving on a conveyor. Row by row, the analyzing device synchronously monitors the light emission on the eggs of the row and detection of the attenuated light of emerging beams. The monitoring includes at least two close cycles of light emission. During the first cycle, which is of short duration to avoid causing glare of the detectors of the detecting device, the coordinates of possible empty cells in a row are determined and stored. During the second cycle, which is of longer duration, the coordinates of fertilized eggs of the row are determined and stored. The egg candling installation advantageously also marks the eggs, depending in particular on whether they are fertilized or not.
