  • Patent number: PP7271
    Abstract: A new ivy geranium showing many favorable new traits that have been lacking in the ivy geraniums currently seen on the market. The variety has proven to be very heat tolerant both indoors and out. The vegetative growth is not as affected by high temperatures and the bloom burns less than is typical of this dark red color. The plant body is much stronger and fuller in habit, when compared to Yale, the current market ivy geranium in this color class. Cuttings are more readily available and root much faster than the current varieties. The deep, rich red color of the semi-double bloom appear velvet-like atop medium green foliage creating a full yet attractive hanging basket.

  • Patent number: RE33266
    Abstract: A folded bit line configured DRAM, with standard even and odd rows of memory cells, also includes spare even and odd rows of memory cells which can be substituted for standard rows found to have defective cells or interconnections. Each of the decoders associated with a standard row includes provision for being disconnected if found to be associated with a defective row. One common spare decoder is associated with one spare even and one spare odd row of memory cells. Each spare decoder is designed normally to be deselected for any address but to be able to assume the address of any disconnected standard row. Disconnection of a standard decoder and substitution of a spare decoder with the appropriate even or odd row are made possible by appropriate inclusion of fusible links which are selectively opened by laser irradiation. The use of one spare decoder with both an even and odd row serves to reduce the number of needed spare decoders and thus reduces overall chip size.

  • Patent number: 4941238
    Abstract: The device provides a fastener which somewhat resembles a slide fastener but which can be made at least substantially fluid-resistant. It comprises a first component (1), of flexible and resilient material, having an engagement formation having a longitudinal groove (6) and longitudinally spaced mating formations (10), and a second component (2), of similar material, having a rib (16) and longitudinally spaced mating formations (19). The components can be progressively engaged by the introduction of the rib into the groove and the interengagement of the mating formations. The latter prevent significant relative longitudinal movement between the components. Each component can be made by extrusion of a blank followed by the formation of the mating formations by a rotary die (123). The components can be engaged and disengaged by means of a slide (52) like that used in a conventional slide fastener.

  • Patent number: 4941239
    Abstract: This disclosure describes a method by which an edge curl that often develops in papermachine forming fabrics can be reduced or eliminated. The method requires the removal of mass from the sheet forming side of the forming fabric. This has the effect of reducing the ratio between the shrink forces acting on the two sides of the forming fabric in the cross-machine direction and, in turn, reduces the tendency for shrinkage to cause the edges of the fabric to curl. Papermachine operational problems associated with edge curl are thereby reduced.
