摘要:
A method of forming a circuit material comprises disposing an adhesion promoting elastomer composition between a conductive copper foil and a thermosetting composition; and laminating the copper foil, adhesion promoting composition, and thermosetting composition to form the circuit material. The adhesion promoting layer may be uncured or partially cured before contacting with the curable thermosetting composition. Preferably the adhesion promoting layer has electrical characteristics such as dissipation factor, dielectric breakdown strength, water absorption, and dielectric constant that are similar to and/or compatible with the electrical characteristics of the thermosetting composition.

In the embodiments described in the specification, a deck/hall extended coverage horizontal sprinkler arrangement has a sprinkler body with frame arms oriented in a vertical plane and a deflector mounted on the frame arms having semi-conical sections on opposite sides of the frame arms. The semi-conical sections are open in the direction toward the sprinkler orifice and include centrally located horizontal openings with vanes extending forwardly above the opening and top surfaces which are flattened and extend outwardly beyond the edges of the conical surfaces of the semi-conical sections.
摘要:
A family of genes has been found in plants, said genes encoding a family of developmental proteins that have homologous structures to the mammalian QM genes. Recombinant molecules which include the QM genes in plants are useful to transform cells and regenerate plants that, as a result, have altered developmental pathways. Methods of producing male sterile plants use recombinant molecules containing either the QM sense genes or antesense genes with appropriate promoters.

Disclosed is a ceiling or wall panel that can be customized with a design or image to yield an aesthetically pleasing appearance. More specifically, a conventional printer is used to print an image on a mat that is laminated to the wall or ceiling tile. The laminating step can be carried out either before or after the image is printed. A number of laminated, printed panels are then used to form a large composite image upon a wall or ceiling. The details of the present invention are more fully described hereinafter.

In the representative embodiments described in the specification, a concealed horizontal sidewall sprinkler has a sprinkler body adapted to be connected to a source of fire extinguishing liquid. A cover support is mounted substantially concentrically to the sprinkler body and has a threaded cylindrical wall extending away from the source of fire extinguishing liquid. The threaded cylindrical wall engages a sleeve which at one end has a slotted cylindrical portion with helically arranged projections to be received in the threads of the threaded cylindrical wall of the cover support. The other end of the sleeve has a flange with a plurality of tabs extending away from the cylindrical portion. A cover is attached by solder to the tabs extending from the flange of the sleeve. The cover also has four slots and is spaced from the flange of the sleeve by the tabs forming an annular gap. Two springs affixed to the flange are interposed between the flange and the cover for urging the cover away from the sleeve when the solder fuses at elevated temperatures. The cover can be frustoconical in shape and the centerline of each slot in the cover can extend substantially in a plane with the axis of the frustoconically shaped cover.

Disclosed herein is a multi-layer golf ball having a soft outer cover. The golf ball has an inner cover layer with a Shore D hardness of 60 or more, and an outer cover with a Shore D hardness of 53 or less. In a particularly preferred form of the invention, the outer cover comprises at least 75% of a soft, ionomeric copolymer formed from a polyolefin, an unsaturated carboxylic acid, and a monomer of the acrylate ester class. The golf ball of the invention has exceptionally soft feel and high spin rates on short shots of 80 yards or less and, particularly, 40 yards or less, while maintaining good distance and average spin on full shots.
