    • The present invention encompasses, in part, a method and apparatus for lens casting in which two molds, preferably formed of plastic, are interconnected or joined together via a ring to form a mold cavity having substantially the same dimensions of the lens to be formed therein. The invention is further directed to compositions and methods used in lens casting. In a first implementation the invention includes a mold having a ring having an interior periphery; a front mold formed of a plastic and having a lens-forming surface, an edge circumscribing the lens-forming surface that is sized to be complementarily received within a portion of the interior periphery of the ring, and a base having dimensions greater than the interior periphery; and a rear mold formed of a plastic and having a lens-forming surface.
    • 本发明部分地包括一种用于透镜铸造的方法和装置,其中优选由塑料形成的两个模具通过环相互连接或连接在一起以形成具有与其中形成的透镜基本相同的尺寸的模腔 。 本发明还涉及用于镜片铸造中的组合物和方法。 在第一实施方式中,本发明包括一具有内周的环的模具; 由塑料形成并具有透镜形成表面的前模具,围绕透镜形成表面的边缘,其尺寸设计成互补地容纳在环的内周的一部分内,以及具有大于内部尺寸的尺寸的基座 周边; 以及由塑料形成并具有透镜形成表面的后模具。

    • Systems and methods enable connection of, and are usable to connect, well servicing equipment to other well equipment, including wellheads, blowout preventers, and other well servicing equipment. The systems comprise connecting apparatus having a male connector and female connector. The male connector comprises an elongate body having an axial bore extending therethrough and a plurality of protrusions extending from the elongate body at an angle relative to the axial bore. The female connector can be adapted for connection with the male connector, wherein engagement between the male connector and female connector communicates the axial bore of the male connector with a bore of the female connector to define a flowpath for communicating a medium. The systems and methods enable the ability to connect or disconnect well equipment remotely without the need of a diver, an ROV, and without the need to bring the well equipment to the surface for disassembly.
    • 系统和方法使得能够将维修设备连接到其他井设备(包括井口,防喷器和其他井服务设备)上并且可用于连接。 该系统包括具有公连接器和母连接器的连接装置。 阳连接器包括具有延伸穿过其中的轴向孔的细长主体和从细长体相对于轴向孔以一定角度延伸的多个突起。 阴连接器可以适于与阳连接器连接,其中阳连接器和阴连接器之间的接合将阳连接器的轴向孔与阴连接器的孔连通,以限定用于传送介质的流路。 这些系统和方法能够远程连接或断开井设备,而不需要潜水员,ROV,并且不需要将井设备带到地面进行拆卸。
