  • Patent number: 4403754
    Abstract: A yarn tension device is disclosed which includes a generally hollow, cylindrical body having an open top and an interior channel of sufficient size to contain one or more tensioning balls. The body terminates downwardly in inwardly converging bottom walls within which are mounted a pair of diametrically opposed ceramic eyelets for yarn inlet and yarn outlet. A flanged roller is horizontally positioned at the bottom of the body in transverse alignment to a plane through the eyelets to apply tension to yarn passing through the eyelets. The body is formed with parallel, planar walls adjacent to the roller flanges to maintain the position and orientation of the roller during yarn tensioning.

  • Patent number: 4401662
    Abstract: Oligosaccharides obtainable from heparin including heparinic constituents of molecular weights ranging from 2000 to 50,000. Said fractions have a Yin-Wessler titer and a USP titer in a ratio of at least 30. They consist of chains constituted by no more than 8 saccharidic moities. They possess a strong antithrombotic activity and are then useful as antithrombotic drugs.

  • Patent number: 4401659
    Abstract: A polymer of peptidic type formed by a chain formed from aminoacyl residues preferably derived of at least one of the amino-acid residues selected from the class consisting of .alpha.,.gamma.-diaminobutyric acid, ornithine, lysine, homo-lysine, of which the lateral amino functions portionally carry peptide branches of which the aminoacyl residues are preferably derived of those selected from the class consisting of alanine, glycine, .alpha.-aminobutyric acid, valine, leucine and proline, the above-said peptide polymer having an average molecular weight comprised between about 50,000 and 250,000, and to which are bound covalently, muramyl-peptide units of which the two first aminoacid residues bound to the muramyl group are stereoisomers of the D series, the second aminoacid residue having the structure of the glutamic acid.This product is useful as anti-infectious agent.

  • Patent number: 4401758
    Abstract: Oligosaccharides obtainable from heparin including heparinic constituents of molecular weights ranging from 2000 to 50,000. Said fractions have a Yin-Wessler titer and a USP titer in a ratio of at least 30.They consist of chains substituted by no more than 8 saccharidic moities. They possess a strong antithrombotic activity and are then useful as antithrombotic drugs.

  • Patent number: 4399823
    Abstract: A loose probe alarm in which a temperature responsive element (14) arranged for attachment to a body is periodically heated (20, 22, 26) and the effects of self-heating of the temperature responsive element are monitored (32, 36, 38) to determine whether the temperature responsive element has been dislodged from the body. The alarm is arranged to sense during the heating period of the temperature responsive element the difference in the amount of heat dissipated by the temperature responsive element when it remains in contact with the body to which it has been attached and when it has been dislodged from this body.

  • Patent number: 4398854
    Abstract: The boring head has a tool holder in which the cutting tool is retained by a clamping screw. The tool holder is radially adjustable by an adjustment screw having a fine thread. The adjustment screw has a flange and a pressed-on knob which bears an adjustment scale. Between the knob and the flange, the annular portion of an insert is introduced, free of axial play. The annular portion of the insert is connected to the boring head by a set screw.The insert with the annular portion also is provided with a clamping lip which can be pressed against the tool holder by a locking screw. The tool holder with its fine adjustment can be separately mounted and constitutes an easily replaceable unit.

  • Patent number: 4394933
    Abstract: Capsule orienting apparatus in which misoriented asymmetric capsules inadvertently passed by a rectifying unit are segregated from properly oriented capsules. Capsules (12) are delivered by a rectifying drum (14) to capsule carrying pockets (38) in a segregating drum (36) which have recessed portions (38a) sized to loosely receive properly oriented capsules and tightly receive misoriented capsules. As the loosely held, properly oriented capsules pass a discharge point, they are released. The tightly held, misoriented capsules remain in the segregating drum (36) past the discharge point and are ejected from the segregating drum downstream from the discharge point.
