  • Pushpiece for a diver's timepiece
    Patent number: 5299179
    Abstract: This pushpiece (1) for a timepiece includes a movable head (3) slidingly mounted on a tube (4), said head partially enveloping such tube. The head exhibits a central cylindrical core (5) which penetrates into the tube, at least one O ring seal (6) being located between the tube and the core. A return spring (7) urges the head towards the exterior. The core (5) is extended by a stem (8), the diameter of which is greater than the diameter of the core, the spring being arranged between the stem and the tube. In this manner the spring is located in a sealed zone of the pushpiece and the mean diameter of the O ring seal is less than the mean diameter of the spring.

  • Serial register stage arranged for connection with a single bitline
    Patent number: 5299159
    Abstract: A dual-port memory includes an array of dynamic storage cells and a serial register having a plurality of static stages. Each stage of the serial register is arranged for receiving a data bit from a selected storage cell of the array. A plurality of bitlines is interposed between the storage cells of the array and the stages of the serial register. At one time only a single selectable bitline is arranged for interconnecting each of the columns of storage cells with each of the stages of the serial register. Each stage of the serial register includes a latch disabling circuit for selectively enabling and disabling coupling from an output of one amplifier to an input of another amplifier. By disabling such coupling, new data easily can be written into the serial register stage. A keeper circuit in each stage of the serial register reduces power consumption.

  • Sialic acid glycosides, antigens, immunoadsorbents, and methods for their preparation
    Patent number: 5296594
    Abstract: The stereochemistry of sialylation of an acceptor saccharide to obtain an .alpha. (2-3) or .alpha. (2-6) linkage is controlled to favor the a anomer by use of an aromatic ester of the sialyl reagent. The resulting intermediate .alpha. (2-3) and .alpha. (2-6) sialylated intermediate disaccharide blocks are useful in the synthesis of antigenic substances which can be used to raise antibodies useful in diagnosis and therapy, and can themselves be used as reagents in various applications. The preparation of the tetrasaccharide antigens corresponding to the 19-9 and sialyl-X antigens characteristic of malignant tissue illustrates the application of this method.
