    摘要: Process for the production of hydrogenated, ring-opened metathesis (co)polymers from cyclic olefins using the ruthenium-carbene complexes of the general formula (I) ##STR1## in which R.sub.1 and R.sub.2 mutually independently mean hydrogen, C.sub.2 -C.sub.20 alkenyl, C.sub.1 -C.sub.20 alkyl, aryl, C.sub.1 -C.sub.20 carboxylate, C.sub.1 -C.sub.20 alkoxy, C.sub.2 -C.sub.20 alkenyloxy, aryloxy, C.sub.2 -C.sub.20 alkoxycarbon-yl,C.sub.1 -C.sub.20 alkylthio, which may optionally be substituted by C.sub.1 -C.sub.5 alkyl, halogen, C.sub.1 -C.sub.5 alkoxy or by phenyl optionally substituted by C.sub.1 -C.sub.5 alkyl, halogen, C.sub.1 -C.sub.5 alkoxy;X.sub.1 and X.sub.2 mutually independently mean any desired anionic ligand;L.sub.1 and L.sub.2 mutually independently mean any desired neutral electron donorand two or three of X.sub.1, X.sub.2, L.sub.1 and L.sub.2 may furthermore together form a multi-dentate chelating ligand,as catalysts for the polymerisation stage, wherein the catalyst is optionally modified after polymerisation by adding a modifier and the polymerisation product is hydrogenated as a solution (optionally diluted with the same inert solvent as during polymerisation or with another inert solvent) without addition of an extra hydrogenation catalyst at temperatures of 0.degree. C. to 200.degree. C. preferably of 35.degree. C. to 150.degree. C. under a hydrogen pressure of 2 to 200 bar, preferably of 10 to 50 bar, wherein at least 60%, preferably at least 95% of the olefinic double bonds are saturated.

    摘要: A handle houses a dental floss supply reel and a dental floss take-up reel in separate chambers. Movement and tension of a single long strand of dental floss through a pair of arched flossing arms is controlled by a new dental floss supply control knob, and a used dental floss take-up control knob. Spring loaded ratchets control the action of the reels. A hygienic cover protects the flossing arms. A small brush stored in the cover cleans the used dental floss of debris.

    摘要: A mounting apparatus for a data storage device (10) with a plurality of protrusions (14) formed thereon. The mounting apparatus comprises a bracket (30), a pair of retaining members (50), and a pair of latches (70). A pair of openings (40) is defined in each side plate (34) of the bracket. The retaining members are attached to inner sides of the side plates and each comprises a pair of retaining portions (58). The retaining portions each comprise a resilient arm (60) and a positioning portion (58). The protrusions are limited in a space defined by the resilient arm and the positioning portion. A hook (610) is formed on the resilient arm and extends through corresponding opening. The latches are pivotally attached to outsides of the bracket and ends are received in corresponding hooks. The data storage device is released from the bracket by pressing the latches.
