Abstract: The invention relates to a rotary machine comprising a rotor (6) bearing a packing (9) in the form of a ring which is at least partially made from a flexible, fluid-permeable material. The inventive machine also comprises variable-speed drive means for rotating the rotor (6) and means which enable the aforementioned packing (9) to be deformed in response to a variation in the rotational speed of the rotor (6). As a result, the machine can produce an air flow, extract material contained in said flow and perform a self-cleaning cycle.

Abstract: The invention provides peptides which are expressed by the env gene of a non-M, non-O HIV-1 virus, in particular a strain designated YBF30. The invention also provides fragments of the peptides that including the V3 loop region and their corresponding nucleotide sequences. The invention further provides kits including diagnostic reagents containing these molecules or immunogenic compositions containing these peptides, as well as methods for screening and typing non-M, non-O HIV-1 viruses and HIV-1 viruses expressing these peptide and/or nucleotide sequences.

Abstract: A process for establishing secure communication between particular communicating units via a channel of a telecommunication network encodes data embodying information to be selectively transmitted from a transmitter unit to one or more particular receiver units prior to transmission using an error detecting code enabling reliable recovery of the information on reception. For security reasons, the error detecting code used to encode the information is encrypted using an enciphering key defined by application of a time dependent variation law. Alternatively, the error detecting code used to transmit information can be selected by application of a time dependent variation law.

Abstract: The device of the clevis type for handling materials, notably lifting or hauling operations, comprises two clevis branches connected by at least two stems which have non aligned parallel axes and at least one of which is slit longitudinally, a flat flexible tie in the form of a strap having one at least of its ends secured against motion by friction on the slit stem with the strap penetrating the associated slot and being lockingly wound on the slit stem, and means being provided for locking said slit stem in rotation about its axis.

Abstract: Under the action of relative motion between a hoisting machine support and a load, a movable component such as a pulley-block carried by the hoisting machine is capable of free displacement under gravity between two end positions of abutment when that end of the movable component which is intended to cooperate with the load is stationary with respect to the load, thereby compensating for any variation in distance between the load and that portion of the hoisting machine which carries the movable component. The equipment unit is designed primarily for hoisting operations performed at sea or on wharves.

Abstract: The pulley-block balance comprises at least one loose pulley, a hollow coaxial support fitted with ball-bearings for supporting the pulley or pulleys, and a load-lifting hook. Coupling means between the hook and the support comprise a movable member which is capable of undergoing displacement at least at the point of application of the force arising from the load and is subjected to a restoring action in the direction opposite to the force. The movable member controls load-indicating means as a result of its displacement.

Abstract: The hollow rotating component such as a pulley, toothed wheel, drum and the like is mounted on a stationary hollow coaxial component in the form of a ring. The ring is coupled to a stationary support by means of a rigid mechanical part so arranged as to ensure that the internal space which is common to both components is left completely unobstructed and also given freedom of access. A detector or transducer for measuring deformations is mounted between the ring and the support.
