Abstract: A fiber optic cable system, such as a preterminated fiber cable, includes a main cable and one or more drop cables connected to the main cable at spaced apart locations along the main cable. The drop cable is spliced to the main cable using a splice closure including a fiber guide that secures spliced together end portions of the respective fibers in a longitudinally extending direction and devoid of any slack coils of optical fibers. Accordingly, the overall diameter of the splice closure is relatively small thereby permitting the cable system to be stored on a reel and to be readily placed within small diameter conduits. The splice closure includes a heat recoverable housing surrounding the fiber guide. Cable sheath end portions are sealed by melting C-shaped bodies of heat flowable material positioned adjacent cable sheath end portions.

Abstract: A bowling ball is made with a shell and a core of different compositions, with the core having a greater density than the shell so that the finished ball will have a predetermined weight; and the core also having a maximum dimension along an axis passing through the top of the ball where the finger holes are to be drilled, and a minimum rotational inertia around the same axis. The core is temporarily supported on a pin while the shell is cast around it, and the hole left by the pin is filled with a material of distinctive appearance to designate the top where finger holes should be drilled.

Abstract: A bowling ball has a surface made from a material containing a minor quantity of functionally terminated liquid elastomer combined with a major quantity of resin-forming material reactive with the functional end groups of the elastomer, and has a greatly enhanced coefficient of friction against ordinary bowling lane surfaces, permitting superior control of the path of the ball and therefore better scores by the bowler. Such surface compositions are preferably made from a liquid polyester resin of the type which is hardenable by a peroxide, with addition of a liquid vinyl-terminated diene polymer or copolymer in a quantity amounting to about 10% to 35% of the mixture.

Abstract: An elongated bimetal member has a transverse curvature opposing temperature warp and a longitudinal curvature aiding temperature warp. The transverse curvature maintains the member straight in a longitudinal direction until the sum of the longitudinal temperature warp forces and the bias of the longitudinal curvature exceed the retaining forces of the transverse curvature.

Abstract: There is disclosed a method and apparatus for communicating in multi- and single story building structures and parts thereof wherein a signal voltage source is connected to a metallic building structural member which is an integral part of the building. Multi-story buildings at least as high as fifty stories have been excited by utilizing a structural member such as a vertically extending stand pipe and like structural members. In such multi-story structures and in smaller structures such as one story frame, masonry and metal building structures, one of the terminals from the voltage source may be connected to earth ground by stakes or rods driven in the ground. Resistance means are inserted in the lines to limit the short circuit current and to provide a degree of impedance match.

Abstract: An electrical sequencing relay has an elongated bimetal member with a transverse curvature opposing temperature warp and maintaining the member straight in a longitudinal direction until longitudinal temperature warp forces exceeds the retaining forces of the transverse curvature. A slidable insulative operator is engaged by a free end of the bimetal member to operate an electrical switch when the bimetal member abruptly changes its longitudinal curvature.
