Abstract: A cutter head includes a first member, a cutting bit, and a second member. The first member includes a first end and a second end and includes a first mass. The cutting bit is coupled to the first member proximate the second end. The cutting bit includes a cutting edge rotatable about the axis. The second member is rotatable about the axis and includes a second mass eccentrically positioned with respect to the axis. Rotation of the second mass causes the first member and the cutting bit to oscillate.

Abstract: A method for removing material from a rock wall. The method includes moving a cutting edge through the rock wall to create a first slot in the rock wall, moving the cutting edge through the rock wall to create a second slot in the rock wall, the second slot being separated from the first slot by an uncut portion, the uncut portion defining a base surface attached to the wall, cutting a notch into the base surface of the uncut portion, and applying a force on the uncut portion to break the uncut portion away from the wall.

Abstract: A cable splice closure includes a closure body having mating surfaces sealed together. An end seal in the closure has an opening for receiving a cable. The end seal is sealed to the closure body by an adhesive bond. An adhesive injection port in the end seal. The port is provided to communicate an adhesive injected into the end seal to bond surfaces of the end seal and the cable to be received, into a sealed unit. The adhesive is a low surface energy adhesive based on acrylic monomers with organoborane are complexes.

Abstract: An end seal assembly is adapted to seal the space between at least one cable and a closure to restrict fluid transfer through the seal. The end seal assembly includes an end seal having a body formed from an elastic, flexible material. The body includes a core portion and an extended tail portion. The core portion has an outer peripheral surface, spaced ends, and a wall forming at least one cylindrical opening through the core portion. The cylindrical opening extends between the spaced ends. The wall has two edges communicating with the outer peripheral surface of the core portion to define between the two edges an entrance slot to the at least one of the cylindrical openings. The extended tail portion is integral with and extends from the outer peripheral surface of the core portion. Moreover, the tail portion has a surface tangential to the wall forming the at least one opening.

Abstract: An end seal for a cable splice closure includes a core portion having a slot for receiving a cable. A tail portion, extending from the core portion, is of sufficient length and flexibility to be extended over the slot. An adhesive injection port is provided in the core portion to communicate an adhesive injected into the injection port to the slot to bond into a sealed unit the surfaces of the end seal and the cable to be received. The adhesive is a low surface energy adhesive based on acrylic monomers with organoborane amine complexes.

Abstract: An end seal for splice closures or for terminals including a body having a core portion and an extended tail portion of a flexible resilient material. The core portion has an outer periphery and openings extending through the core. The openings communicate with the outer periphery. A tail portion is integral with and extends from the core periphery to be wrapped about the core and the cables to be placed in the openings. A sealant strip extends around the cables and between the abutting peripheral surface of the core and the wrapped tail portion. The strip is responsive to electrical or electromagnetic stimulation for heating the sealant strip and causing the strip to bond with adjacent contact surfaces of the cable and the body.

Abstract: An end seal for splice closures or for terminals comprising a core portion of a flexible resilient material, which core portion has an outer periphery and openings extending through the core portion, which openings communicate with the outer periphery, and a tail portion which is integral with and extends from the core portion periphery to be wrapped about the core portion and the cables placed in the openings thereof for filling the space between the core portion and the closure end surface.

Abstract: Splice closures can be readily sealed by wrapping the cables with a mastic and then forming an end for a performed closure by placing the halves of a split ring about the mastic and drawing the halves closed by a toggle fastener including an arcuate leg connected at one end to one half and joined intermediate the fulcrum and handle of a lever supported on the other half to squeeze the mastic about the cables as the halves are drawn together. The closure may be sealed to the ring by a rolling O-ring.

Abstract: A microprocessor-based audiometer for use with children. A color visual display unit is used to display an image digitally stored in memory or on disk drive to attract the childs attention and hold its concentration during testing.The child activates a response switch upon detecting the tones produced by audiometer to the generator. Correct responses are reinforced by progressive alteration of the displayed image to increasingly desirable states.

Abstract: A fiber optic splice closure for protecting the splice made into a transmission cable, containing a plurality of fibers which are to remain unsevered, comprises a base to which the cable is anchored and in which slack fibers in the uncut cable are looped and stored free of transverse barriers. The seal is made with the cables and the base by a mating cover provided with a second area to receive splice trays and slack fibers selected from the cable for splicing.
