Abstract: A web tensioning device utilizes a dancer arm which can be positioned by a controlled servo motor. In a preferred embodiment, the controller for the servo motor receives an input signal based on the acceleration (positive or negative) of the dancer arm and implements a torque component necessary to maintain predetermined web tension, for example, an applied torque component that changes the position of the dancer arm. The controller may also receive additional input signals indicative of the acceleration of the web itself.

Abstract: This invention relates to a novel approach for identification of T-cell epitopes, that give rise to an immune reaction in a living host. By means of this novel method biological compounds can be generated which have a no or at least a reduced immunogenicity when exposed to the immune system of a given species and compared with the relevant non-modified entity. Thus the invention relates also to novel biological molecules, especially proteins and antibodies, obtained by the method according to the invention.

Abstract: Modified forms of hirudin having improved properties are disclosed. The modified hirudin compounds are hirudin variants comprising amino acid substitutions in the sequence of hirudin. Peptide molecules consisting of the amino acid residue sequence CILGSDGEKNQCVTGEGTPKPESHNDGDFE (SEQ ID NO: 1) or a sequence consisting of at least 9 consecutive amino acid residues of SEQ ID NO: 1 having a potential MHC class II binding activity are disclosed. The peptide has a stimulation index of >1.8 in a biological assay of cellular proliferation, in which the index is defined as the value of cellular proliferation scored following stimulation by the peptide and divided by the value of cellular proliferation scored in control cells that have not been exposed to the peptide.
Abstract: A delivery vehicle for a silver ion source such as silver nitrate and the like, suitable for use in the treatment of menorrhagia, comprises a plurality of physiologically inert beads bearing a tissue cauterizing amount of a silver ion source. Preferably the beads are made of a physiologically inert polymer, ceramic or stainless steel. The silver ion source preferably is silver nitrate and can be substantially pure silver nitrate, or can comprise silver nitrate in combination with a physiologically tolerable binder or a diluent. Suitable binders include physiologically tolerable synthetic polymeric binders, polysaccharide binders, and the like. Diluents can include other salt materials such as potassium nitrate. The beads are useful in treating menorrhagia of a mammalian uterus. The beads can be delivered to the uterus via a catheter, and are distributed throughout the uterine cavity by uterine massage or like expedient. Silver ions are delivered to the endometrium and cause necrosis of the endometrial tissue.
Abstract: An isolated peptide useful as a selective antagonist of mammalian R-cadherin comprises 3 to 30 amino acid residues, three contiguous residues of the peptide having the amino acid sequence Ile-Xaa-Ser; wherein Xaa is an amino acid residue selected from the group consisting of Asp, Asn, Glu, and Gln. Preferably Xaa is Asp or Asn. In one preferred embodiment the peptide is a cyclic peptide having 3 to 10 amino acid residues arranged in a ring. The selective R-cadherin antagonist peptides of the invention are useful for inhibiting the targeting of stem cells, such as endothelial precursor cells, to developing vasculature, for inhibiting R-cadherin mediated cellular adhesion, and for inhibiting retinal angiogenesis.

Abstract: A combination of a flame arrestor with a reflection suppressor is provided which not only arrests an advancing flame front, but also suppresses or mitigates a reflection wave that is generated by a pressure wave that passes through the combination and continues on to a pipe restriction what generates a reflection wave that proceeds back to the combination. At the combination, the reflection suppressor suppresses and/or mitigates the reflection wave, thereby avoiding a heightened pressure in the combination that could cause a re-ignition and a new flame front and pressure front. The reflection suppressor has a tapered profile that permits a pressure wave to pass along and past the reflection suppressor as it leaves the combination but that impedes and mitigates a returning reflection wave produced by the pressure wave striking a pipe restriction and causing such a returning reflection wave.
