Title: Diphosphines bonded to side chains of polymers, and metal complexes thereof
Inventor: PUGIN BENOIT
IPC: C08F8/44
Filed: 1996-02-22
Abstract: The invention relates to polymers having structural repeating units of at least one monomer MM which contains a hydroxyl group or a primary or secondary amine group as a functional group bonded directly or in a side chain, wherein the functional group is bonded via a bridge group Q formed by a diisocyanate to the hydroxyl group or primary or secondary amino group of an aliphatic, cycloaliphatic, heterocycloaliphatic, aromatic or heteroaromatic ditertiary diphosphine, the phosphine groups of which are bonded to a carbon chain in the 1,2-, 1,3-, 1,4- or 1,5-position relative to one another. The invention also relates to a process for their preparation and to rhodium and iridium complexes with these diphosphine ligands. Using these rhodium and iridium complexes, optically pure compounds which are valuable intermediates for the preparation of biologically active ingredients, in particular in the field of pharmaceuticals and agrochemicals, can be obtained in a hydrogenation process which is likewise according to the invention. Thus, for example, it is possible to prepare from secondary amines, in particular N-carbalkoxymethylamines, 5-imidazolecarboxylic acid derivatives which have a herbicidal action and can be used for weed control (EP-A-0 207 563). The optically pure .alpha.-aminocarboxylic acid esters are suitable for peptide syntheses. After the hydrogenation, the catalysts can easily be separated off, if appropriate purified and re-used.

Title: Method and apparatus for making a paint roller
Inventor: SEKAR CHANDRA
IPC: B29C53/58
Filed: 1996-02-29
Abstract: A method and apparatus for making reusable paint rollers comprised of a core formed of thermoplastic material. The core is formed by helically winding one or more strips of thermoplastic material about a stationary mandril. A layer of adhesive is then applied to the outer surface of the core whereupon a cover, applied as a strip of material or as blown on fibers, is bonded thereto. The core may also be formed by applying liquefied thermoplastic material to a driven belt which transfers the thermoplastic material to the mandril.  The paint roller may also be made by bonding, in a single step, the fabric cover to the wound strip wrapped about the mandril. The cover is then pressed onto the core to form a tight and secure bond therebetween. The mandril may also be cooled to speed the production process.

Patent CA-2181000-A1 (CA)
Title: System and method for determining pitch contours
Inventor: OLIVE JOSEPH PHILIP
IPC: G10L25/90
Filed: 1996-07-11
Abstract: A system and method are provided for automatically computing local pitch contours from textual input to produce pitch contours that closely mimic those found in natural speech. The methodology of the invention incorporates parameterized equations whose parameters can be estimated directly from natural speech recordings. That methodology incorporates a model based on the premise that pitch contours instantiating a particular pitch contour class can be described as distortions in the temporal and frequency domains of a single, underlying contour. After the nature of the pitch contour for different pitch contour classes has been established, a pitch contour can be predicted that closely models a natural speech contour for a synthetic speech utterance by adding the individual contours of the different intonational classes and adjusting the boundaries of these to match the boundaries of the adjacent intonation curves.

Abstract: A cable controller is formed by a housing having a cavity into which one end of a handle is received and mounted for a pivotal movement on a pivot pin extending across the housing. The pivot pin is received within a L-shaped slot adjacent to one end and the top of the handle and an abutment is provided projecting outwardly from the bottom of the handle in position to engage the rim of the cavity. A control cable is connected to the handle positioned about midway between the abutment and the slot. The slot and the abutment are positioned so that movement of the handle in a first direction pivots the handle about the pivot pin and extends the cable and movement of the handle in the opposite direction pivots the handle about the point of contact between the abutment and the rim of housing to move the pin along the slot into a short section of the L-shaped slot to thereby extend the cable now lock the handle in a parking position.
