Abstract: The present invention pertains to a crosslinkable binder resin comprised of an acrylate copolymer backbone having as pendant groups water soluble half esters of dicarboxylic acid and crosslinkable olefinic groups which contain an activated ethylenic unsaturation, such as (meth)acryloyl groups. The (meth)acryloyl groups can be crosslinked by polyfunctional crosslinking agents such as amino or blocked amino crosslinkers. The water-soluble half esters preferably are formed by the reaction of pendant hydroxy groups with unsaturated cyclic anhydrides (the unsaturation providing an additional crosslinking site). The (meth)acryloyl groups preferably are formed by the reaction of pendant epoxy groups with (meth)acrylic acid or derivatives thereof.

Abstract: An analytical reader device having an elongated fixed standard tray supporting thereon a strip of standard wells and an elongated movable sample tray supporting thereon a strip of sample wells. A track arrangement connects and allows the movable sample tray to slide along the fixed standard tray. A rack gear is secured along the side of the movable sample tray opposite to the track arrangement. A geared dial is rotatably supported on a support plate secured to the fixed standard tray. The teeth of the geared dial mesh with the teeth of the rack gear so that as the movable sample tray slides the dial rotates. When a sample well is positioned adjacent the visually similar standard well, the dial is turned so that the correct concentration reading thereon appears through a fixed readout window.

Abstract: The method for bidirectional data transmission according to the time-division principle enables the synchronisation of plesiochronously running packet timing signals with no increase in the data stream jitter component which normally occurs. Two bidirectionally and continuously running, plesiochronously clocked data streams (S12, S21) are divided up into data packets which are exchanged within cycles (Z) between two transceiver stations (SE1, SE2). The cycles (ZSE1, ZSE2) plesiochronously running in both stations (SE1, SE2) are synchronised through modification as required of the cycle length (ZSE2) and corresponding modification of the packet length of the data packets transmitted from station (SE2) to station (SE1). A circuit arrangement is furthermore indicated for carrying out the method. <IMAGE>

Abstract: In the determination of motion vectors for the blocks of a source image sequence, hierarchical search methods are usually applied by using a block-matching error criterion. The motion vector found in a search step is used as starting value for improvement in subsequent search steps. In the invention, at least two motion vectors, in which the error criterion is smallest, are determined in a first search step in an image with reduced resolution. These motion vectors are interpolated to sub-pel accuracy and brought to a size which has validity for the non-reduced image. In the second search step, the search is refined in a small area surrounding these motion vectors and the zero vector and the motion vector is determined, for which the error criterion supplies the smallest value. <IMAGE>
