  • Patent number: 4939122
    Abstract: The invention relates to muramyleptide derivatives resulting essentially from the conjugation or the coupling, as the case may require, through an arm, between a muramylpeptide and a group containing two atoms contiguous with one another to each of which is attached a lipophile chain comprising from 8 to 100 carbon atoms, preferably from 14 to 24 carbon atoms. The derivatives according to the invention are endowed with remarkable stimulating properties with respect to the activation of macrophages, of which they amplify the tumoricidal properties.

  • Patent number: 4914351
    Abstract: Photomultiplier dynodes (D.sub.1, D.sub.2 . . . ) each comprise two spaced planes (D.sub.11 and D.sub.12) made up elementary laminations having a cross-section in the form of an isosceles triangle which is symmetrically disposed relative to the inlet window of the photomultiplier tube. The laminations in the two consecutive planes of a single dynode stage are offset relative to each other to constitute a baffle, and are disposed in such a manner that electrons leaving the first plane pass through the second plane without striking the laminations thereof. The distance Z.sub.1 between two dynode stages is large relative to the distance Z.sub.O between the two planes of a single dynode, and is chosen as a function of the electric field in such a manner that the secondary electrons from the upstream stage strike a limited number of the laminations in the downstream stage with a concentrated distribution.

  • Patent number: 4773133
    Abstract: The method for relaxing knitted fabrics according to the invention uses humidity, heat and agitation of the fabric. Said agitation is caused by projecting the fast-advancing fabric against a rigid support on which the then nontensioned fabric piles up.The projection of the knitted fabric is obtained by driving said fabric by friction and without slipping, by means of a movable element of projection into the outlet zone from which the fabric is projected against a receiving zone of the support, which receiving zone is situated close to the outlet zone of the projecting element and substantially transversely to the direction of projection.The movable element of projection is a movable belt turning over two cylinders of which one at least is a driving cylinder, whose driving speed can reach 600 meters/minute.

  • Patent number: 4525705
    Abstract: The system according to the invention comprises a sensor composed of a movable unit formed by an electrical circuit in which are placed two supple blade switches closed by a rocking member in response to the presence of a yarn. Said circuit comprises a conductor wound on a magnetic core. The data transmitting device comprises a fixed looped conductor of which one part is parallel to the path followed by the sensor and traverses the core. Means are provided for generating oscillations in the looped conductor, as well as means for detecting a variation in the oscillating conditions induced by a change of state of the electrical circuit due to the closure of one switch and indicating that the sensor has met up with a yarn. Due to the detection of the variations in the oscillating conditions, it is possible to find out the number of breakages occurring in the textile machine.

  • Patent number: 4473736
    Abstract: A plasma generator comprises a metallic tube of small diameter inside which can circulate a gas such as argon at a small flow rate, which is discharged at the front end of the tube. The tube is coupled with an energizing structure which can comprise a frequency generator supplying electromagnetic microwaves, via a coaxial connection, a coupling structure allowing the transfer of the energy of the generator to the front portion of the metallic tube. In the absence of a gas current in the tube, the front portion radiates the energy transmitted to it in the manner of an antenna. When a gas is discharged at the end of the tube, said energy allows maintaining a plasma in front of the latter.This plasma generator device is usable in many applications, such as a blowtorch a light source or torch usable in spectrography, a plasma motor or an ion source.

  • Patent number: 4458245
    Abstract: The length and width of fissures in a bore hole is determined by alternately flowing liquid into and out of the formation from an isolated zone of a bore hole, at different frequencies, and measuring the dynamic pressure of the flowing fluid. The length of fissures in the isolated zone is determined from frequency peaks at high pressure to flow ratios, and the thickness of the fissures is determined from variations of pressure-flow ratios with frequency by comparison with known data. Sonde apparatus for practicing the method is also disclosed.

  • Patent number: 4435347
    Abstract: A method for forming articles such as crates in which sides of the crate extend generally perpendicular to the base of the crate. The method includes forming a layer of loose binder coated wood particles, precompressing selected portions of the layer which form the sides of the crate, bending the precompressed portions upwardly, inserting the so formed layer in a mould and compressing the layer in the mould to form the desired article. The initial layer can be slightly compressed to hold the particles together and the base of the article can also be slightly precompressed but to a lesser extent than the portions which form the sides.

  • Patent number: 4432295
    Abstract: The present invention relates to a method and apparatus for processing rectangular pieces of fabric wherein the piece of fabric is moved in a first direction until the front edge reaches and is held in a predetermined front position, whereas the remaining part of said piece continues to move in said first direction until the rear edge reaches and is held in a predetermined rear position. The piece is thereafter moved in a second position while the front and rear edges are kept apart at a predetermined distance, and the aforesaid edges are hemmed simultaneously by hemming machines. The method and device according to the invention are used for hemming pieces having two parallel edges, and in particular rectangular pieces cut from a continuous web of fabric, such as for example floor cloths.

  • Patent number: 4427659
    Abstract: The invention relates to novel compounds of the muramyl-peptide type and to their uses. The muramyl-peptides according to the invention comprise at least two aminoacyl residues in the peptide chain, the second of these aminoacyl residues being D-glutamyl, and they are characterized in that the nitrogen of the first amino-acyl, and forming part of the pepetide linkage connecting the muramyl group to the peptide residue, is substituted by an alkyl group. These compounds are useful notably for the preparation of pharmaceutical compositions, in particular by reason of their regulatory properties on the immune responses of the organism.

  • Patent number: 4399381
    Abstract: In a homopolar dynamoelectric machine in which a magnetic flux moves across a generally cylindrical clearance space between the stator and rotor, counterproductive magnetic fields produced by axial electric currents are avoided by providing, on the mutually confronting surfaces of the stator and rotor, nonmagnetic electrical conductors which are electrically insulated from the magnetic portions of the stator and rotor. The conductors are connected together electrically by contacts, providing an electrically conductive loop which encloses no magnetic members. Leads from the electrically conductive loop may be connected to an external circuit.The electrical conductors in one embodiment are of solid cylindrical shape, and in other embodiments are formed of spaced bars as in a squirrel cage. When spaced bars are used, the bars on one member are axially oriented and the bars on the other member are arranged in two sets which are equally but oppositely inclined to the machine axis.
