IPC: B65C9/18
Filed: 1993-05-17
Abstract: Linerless labels are produced by feeding a tape having a release coated face and an adhesive face to a hardened anvil vacuum cylinder, utilizing a non-stick circumferential surface feed roll. A knife blade on a cutting cylinder is rotated into contact with the tape at the anvil cylinder to cut the tape into linerless labels, and release liquid is applied to the blade after each cut. From the anvil cylinder the labels are deposited on a plurality of spaced conveyor tapes of circular cross section with the adhesive faces contacting the conveyor tapes. A vacuum chamber assists in holding the labels on the conveyor tapes. The release coat faces of the labels conveyed by the conveyor tapes may be heated and then printed with hot melt ink from an ink jet printer.      The labels are separated from the conveyor tapes using a peeler roll and non-stick stripper rings, and then immediately contact a moving web or other elements to which they are to be applied, with the label and web passing through nip rolls to activate the pressure sensitive adhesive.

Abstract: L'invention est un récepteur (100) à évaluation améliorée des paramètres de pondération de signaux. Ce récepteur reçoit des signaux (101) contenant des données codées. Un circuit de prise de décisions (106) reçoit ces données et produit un premier paramètre de pondération de signaux qui est utilisé pour modifier les données en question, lesquelles sont ensuite décodées. Les données décodées sont ensuite recodées au moyen d'une méthode similaire semblable à celle utilisée par l'émetteur. Ces données recodées sont utilisées pour calculer un second paramètre de pondération de signaux qui, à son tour, est utilisé pour modifier une réplique stockée du signal (101). La version modifiée de la réplique stockée est ensuite décodée, ce qui donne une évaluation plus précise de l'information contenue dans le signal (101) reçu par le récepteur (100).

Abstract: A management apparatus for volume-medium correspondence information for use in a dual file system is disclosed.  The apparatus has a volume-medium correspondence information management table for storing and managing volume-medium correspondence information during the operation of the dual file system.  A volume-medium correspondence information storage file stores, after a stop of the dual file system, volume-medium correspondence information which was in the volume-medium correspondence information management table immediately before that system stop.  The volume-medium correspondence information is updated in the volume-medium correspondence information management table when the media constituting dual files are to be altered and when the volumes into which the media are to be assembled are to be altered.  During the operation of the dual file system, the latest volume-medium correspondence information in the volume-medium correspondence information management table is written into the volume-medium correspondence information storage file.          When the dual file system is to be re-actuated, volume-medium correspondence information stored in the volume-medium correspondence information file is recovered into the volume-medium correspondence information table after the re-actuation.  When the dual file system is to be re-actuated, the volumes in an off-line state are provisionally allocated to dual files including a blockaded medium on the basis of the volume-medium correspondence information in the volume-medium correspondence information table recovered.

Abstract: A corner element of a puzzle game that constitutes a three-dimensional pictorial representation of a structure such as a building-like structure. The corner element comprises first and second backing members bonded to a flexible lithographic film. A hinge area separates the first and second backing members, allowing to bring them in a corner configuration by folding the lithographic film at the hinge area. The film has an exposed image-bearing surface constituting a pictorial entity that contributes to a complete representation of the structure. The corner element is made from a blank that includes a layer of backing material laminated to the lithographic film. The backing material is die-cut at controlled depth to form the first and second backing members in a spaced apart relationship, separated by a waste strip. Prior to assembling the puzzle pieces, the user is required to peel off the waste strip from the blank in order to form the hinge area between the first and second backing members.

Title: Cytokines with an upaired cysteine residue and conjugates thereof
Inventor: CHANG TSE W
IPC: A61K47/48
Filed: 1992-12-10
Abstract: Disclosed are cytokines which are site-specifically mutated to have one unpaired cysteine residue located apart from the receptor-binding site, and conjugates thereof, in particular, conjugates where a lipophilic group is conjugated to the unpaired cysteine residue, and to such conjugates of cytokines which have an unpaired cysteine residue located apart from the receptor-binding site in the native form. All of these cytokines are of the type such that conjugation of a lipophilic group to the unpaired cysteine residue does not significantly affect the receptor binding or biological acitivity of the conjugated product. Also disclosed are conjugates where a lipophilic group, an antibody, horseradish peroxidase, alkaline phosphatase, fluorescein substances, biotin, or a cytotoxin is conjugated to the unpaired cysteine residue. These fatty acyl conjugated cytokines penetrate better and are retained longer in local sites and can be locally administered to treat, e.g., solid tumors, spinal injuries, the external genital area, the throat, ears, nasal linings, eyes, and skin.

Abstract: The present invention relates to a potentially inexpensive light source for multichannel wavelength-division-multiplexed (WDM) applications.  The high-power amplified spontaneous emission (ASE) from a fiber amplifier, which is already in the optical fiber, is efficiently divided into many channels using a WDM demultiplexer.  This "spectrum-sliced" ASE is used as light sources for WDM systems rather than several wavelength-selected DFB lasers.

Title: New formulations for polyacrylamide matrices in electrokinetic and chromatographic methodologies
Inventor: RIGHTETTI PIER G
IPC: C08F2/46
Filed: 1992-08-05
Abstract: Matrices for electrokinetic and chromatographic separations, based on a unique class of mono- and disubstituted (on the amido nitroagen) acrylamides (e.g., acrylamido-N-ethoxy ethanol, acrylamido-N, N-di-ethoxy ethanol) offer the following ad-vantages: a) strong resistance to alkaline hydrolysis (most zone separations occurring at basic pH values); b) a high hydrophilici-ty and c) greater porosity, due to the larger M r value of the monomers. Such matrices can be prepared as 'chemically cross-linked' gels or as 'physical gels', the latter consisting of'strings' of monofunctional monomer in the absence of cross-linker, at concentrations above the entanglement threshold. It is moreover possible to further increment the gel porosity by polym-erizing it in presence of laterally-aggregating agents (e.g., polyethylene glycol of M r 6-20000 Da), thus obtaining matrices which allow better resolution of large M r proteins and of nucleic acid fragments; by polymerizing the matrix in presence of a gradient of the laterally-aggregating agent, it is possible to obtain a porosity gradient even at constant per cent of monom-ers in the gel. Finally, photopolymerization (e.g., with methylene blue and a redox couple, sodium toluenesulfinate and di-phenyliodonium chloride and light), instead with the standard red/ox catalysts, prevents formation of N-oxides of amines present in the polymerizing solution.

IPC: G09F1/10
Filed: 1994-06-08
Abstract: A picture mounting device (for photographic prints, cards and the like) comprises two or more resiliently flexible transparent strips mounted parallel to each other on a flat surface. The strips have an internal and an external slot configured to easily receive and to clamp the parallel edges of prints to be mounted so that the prints may be inserted and removed quickly and easily from the mounting strips, a minimum of space may be wasted between adjacent prints, the prints are held flat to the surface, the prints remain in full view and the prints are prevented from slipping or falling out, irrespective of the orientation of the base. In one embodiment, the mounting strips are demountably retained in a base so that the distance between parallel strips may be adjusted to accommodate various print sizes and orientations and the clamping tension in the internal and external slots may be adjusted to accommodate prints of various thicknesses.
