Patent number: 5596672Abstract: A method and apparatus for placing two optical fiber ends or, one optical fiber end and another object, in contact with one another is provided. The method involves moving one of an optical fiber and an object toward one another so that they make contact with one another and apply a loading force upon one another. A load sensing device detects the loading force and provides a signal indicative of the load sensed. The invention is particularly useful for placing two optical fiber ends in contact with one another so that predetermined force applied to the optical fiber ends.Type: GrantFiled: June 27, 1994Date of Patent: January 21, 1997Assignee: Fiberlign Division of Preformed Line Products (Canada) Ltd.Inventors: Murray R.

Patent number: 5517792Abstract: A guard assembly for use on a guy-wire of the type having an end terminating in a loop comprises an elongated tubular member of a relatively rigid plastic having a hollow interior throughout its length. The tubular member has a single split extending longitudinally thereof between the opposite ends thereof to allow the tubular member to be installed in surrounding relationship to a guy-wire by being moved laterally thereover with the guy-wire entering the hollow interior through the split. First and second generally diametrically opposed aligned apertures are located adjacent the first end of the tubular member so that they can be aligned with the loop on the guy-wire. An elongated pin-like fastener extends through the first aperture and has head portions at opposite ends with a first head portion located within the hollow interior of the tubular member and being radially compressible to a size to allow the head to be selectfully passed through the second aligned opening.Type: GrantFiled: August 31, 1994Date of Patent: May 21, 1996Assignee: Preformed Line Products CompanyInventors: Raymond J.

Patent number: 5146667Abstract: A cable support assembly including first and second generally mating body members formed of a rigid, dielectric material. A bore defined between the mating body members to receive a cushion member is formed of a dielectric material substantially less rigid than the body member material. Outwardly extending flanges on the cushion member prevent axial movement relative to the body. Similarly, a cooperating tab and notch prevent axial movement between the mating body members. An enlarged boss is formed entirely within the first body member to facilitate a method of stringing cable. The first body member is secured to an associated support structure and the second body member positioned in close proximity. A cable is strung between the body members, the cushion member then received around the cable, and the first and second body members brought into mating arrangement.Type: GrantFiled: December 11, 1991Date of Patent: September 15, 1992Assignee: Preformed Line Products CompanyInventor: Thomas E.

Patent number: 5002351Abstract: An apparatus for fusion splicing optical fibers includes a base member, an arc region, a clamp member, and a biasing arrangement for urging the clamp member along second and third axes as the clamp member is advanced or retracted along a first axis. The clamp member includes three fingers, each imposing a different biasing force to accommodate different sized fibers. The biasing force of the fingers may be selectively altered. A transformer bobbin includes a series of large and small grooves separated by dielectric ridges to maximize the creepage distance. Once an arc is established between opposed electrodes, constant power is provided during splicing.Type: GrantFiled: July 5, 1988Date of Patent: March 26, 1991Assignee: Preformed Line Products CompanyInventors: Attila J.
