Patent number: 12232603Abstract: A rotatable connector formed from two parts, each comprising a body extending from a connecting head having a first face and an opposed second face, the second face having an arcuate tail section on an outer perimeter edge and shaped to be received by a tail socket defined between the first face and a pin extending from a proximal end of the body. When the two parts are engaged, the connecting heads are coaxial to define an axis of rotation. When the parts are rotated on the axis relative to one another, the tail section of the first part travels through the tail socket of the second part and the tail section of the second part travels through the tail socket of the first part, thereby connecting the two parts together. When the parts are rotated in the opposite direction, the parts are disconnected from each other.Type: GrantFiled: November 23, 2022Date of Patent: February 25, 2025Assignee: Sherrill, Inc.Inventor: Michael T Storey

Patent number: 6477310Abstract: When stripping an optical fiber ribbon (7) from its polymer coating the ribbon is clamped at some distance from its end in a cutting and tension unit (3). When the lid (23) of this unit is folded down knifes are pressed into the coating at a side of the unit. The end portion of the ribbon (7) is then clamped in a heating unit (1) which before this clamping operation is moved, against the force from an elastically biased rod (31) extending from the cutting and tension unit, the movement being guided by guide rods (11), to be located directly at the side of the cutting and tension unit (3). The end of the ribbon in the heating unit is heated by a heating plate (5). When the end has become sufficiently hot and the coating is softened, the cutting and tension unit (3) automatically starts to move away from the heating unit (1) by the action of the elastically biased rod (31). Then the knifes start to separate the coating on the end portion from the rest of ribbon.Type: GrantFiled: January 2, 2001Date of Patent: November 5, 2002Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventor: Ion Dumitriu

Patent number: 6439084Abstract: A laminated blade assembly including a stationary blade and a pair of insulation supports and a movable blade and a pair of insulation supports with each blade sandwiched between a pair of supports. Semi-circular grooves formed in the insulation supports and smaller semi-circular grooves formed in blades in alignment with the insulation support grooves creating circular grooves to support and cut the insulation when the stationary and movable blades come together. The support semi-circular grooves of one of the stationary and movable insulation supports are located with their peripheries tangent to a straight line which is not parallel to the center lines of the blade semi-circular grooves.Type: GrantFiled: May 7, 2001Date of Patent: August 27, 2002Assignee: Ideal Industries, Inc.Inventor: Michael J. Ebert

Patent number: 6311581Abstract: The invention relates to an automatic optical fiber stripping machine and, more particularly, to an automatic optical fiber stripping machine, which is practical for stripping optical fibers of different diameters efficiently. The automatic optical fiber stripping machine helps the user obtain the desired length of bared glass core for further standardized coupler, optical passive component manufacturing, and accurately strips optical fibers of different diameters without damaging the glass core.Type: GrantFiled: September 21, 2000Date of Patent: November 6, 2001Inventor: Chao-Jen Hsieh

Patent number: 6273990Abstract: A method for mechanically stripping the protective coating from a silica or glass optical fiber using a polymeric or soft metal blade having a hardness less than that of the glass optical fiber but greater than the protective coating. The blade is preferably selected from a group of polymeric materials, or alternately a soft metal, which is selected or treated so as to not detrimentally oxidize in conventional operating environments. For a silica-containing optical fiber, the blade has a hardness of less than approximately 125 on the Knoop hardness scale, and preferably less than approximately 60 on the Knoop hardness scale. A method of inhibiting damage to the exposed region of the silica-containing optical fiber comprises applying a substance that forms a protective layer to provide a barrier to particulates and moisture, and which does not inhibit subsequent processing of the optical fiber, selected from a group of silane-containing compounds.Type: GrantFiled: June 30, 1999Date of Patent: August 14, 2001Assignee: Corning IncorporatedInventors: Dana C. Bookbinder, Mark L. Morrell

Patent number: 6220119Abstract: Stripping tongs for sheathed electrical cables (K) have two tong arms (1, 2) that can pivot toward one another about a common pivoting shaft (3), counter to a restoring spring the tongs further having cable cross-cutters (4, 5) and cuting blades (6, 7) with associated clamping jaws (8, 9) for stripping cable. The cable cross-cutters (4, 5) and the cutting blades (6, 7) with the associated clamping jaws (8, 9) are disposed adjacently and parallel to one another with spacing, and lie in the common tong closing and opening plane extending transversely to the pivoting shaft (3).Type: GrantFiled: October 27, 1998Date of Patent: April 24, 2001Inventor: Josef Krampe
