Patent number: 5906047Abstract: A grease fitting is made by forming its outer shell in a series of cold forging steps to make a blank with the necessary thread blank at one end, a hexagonal center portion, and with a grease-fitting-mating nipple outline at the other end. Threads are rolled onto the thread blank, and the grease-gun-mating nipple is rolled to smooth and burnish its surface. The grease fitting is then successively drilled to make a hole of three different diameters to form the one-way valve ball seat and two ball spring clearance diameters. The ball and spring are inserted, and the end of the hole is formed over the end of the spring to capture the spring into place.Type: GrantFiled: February 15, 1996Date of Patent: May 25, 1999Assignee: Alemite CorporationInventors: Daniel S. Miller, Jerry D. Shew, Jerry V. Burton, John T. Callicotte, Jr., Gerald F. Kramer

Patent number: 5878030Abstract: An interfacing device having two operational amplifiers that have been manufactured on the same IC die have high-impedance input terminals connected directly to the two conductors of a local area network digital transmission line so as not to load or otherwise upset the impedance or other parameters of the transmission line. The output terminals of the operational amplifiers are connected to and match the input impedance of a digital transmission protocol analyzer. The gain of the operational amplifiers is arranged so as to replicate at the input of the analyzer the signals appearing on the local area network transmission line.Type: GrantFiled: June 19, 1996Date of Patent: March 2, 1999Assignee: Wandel & Goltermann Technologies, Inc.Inventor: W. Brian Norris

Patent number: 5775101Abstract: A refueling cart, for refueling large aircraft at a major airport having pressurized fuel hydrants at loading/unloading aprons, includes auxiliary facilities on the refueling cart that are usually powered by compressed air that is obtained from compressed-air bottles carried on the cart. In order to avoid the labor and annoyance of checking and refilling the bottles of compressed air, a small air compressor is carried on the refueling cart and is powered by a hydraulic motor that is in turn powered by the flowing pressurized fuel. A variable-flow valve is placed in the path of the fuel flowing from a hydrant to the airplane. The pressure generated across the variable-flow valve by the flowing fuel pushes some of the fuel in a path that bypasses the variable-flow valve. That bypass path includes the hydraulic motor, and the bypassing fuel at the pressure difference generated by the variable-flow valve drives the fluid motor. The fluid motor, in turn, drives the air compressor.Type: GrantFiled: August 8, 1997Date of Patent: July 7, 1998Assignee: Beta Fluid Systems, L.L.C.Inventor: F. Paul Dunlevy

To avoid the labor and annoyance of checking and refilling the bottles of compressed air, a small air compressor is carried on the refueling cart and is powered by a fluid motor that is in turn powered by the flowing pressurized fuel. A variable orifice is placed in the path of the fuel flowing from a hydrant to the airplane. The pressure generated across the variable orifice by the flowing fuel pushes a small amount of fuel in a path that bypasses the orifice. That bypass path includes the fluid motor, and the bypassing fuel at the pressure difference generated by the orifice drives the fluid motor. The flow of fuel to the airplane is not constant but varies as the planes tank(s) are filled.Type: GrantFiled: June 21, 1995Date of Patent: March 11, 1997Assignee: Beta Fluid Systems, L.L.C.Inventor: F.

Patent number: 5590159Abstract: To recognize a specific pattern of bits anywhere within a high-speed bit stream of data, the serially-received bytes of the bit stream are first converted to parallel or simultaneously-presented, eight-bit bytes. Received bytes are used as the addresses of two SRAMs. A byte of the desired pattern is recognized by having that byte address a memory location of one of the SRAMs in which a binary "1" has been stored at the bit location within that memory location that corresponds to the received byte's position within the expected bit pattern. The other seven bit locations within that memory byte have binary "0s" stored in them. The outputs from the two SRAMs are gated to look for a sequence of two successive bytes of the expected pattern. A binary "1," signifying recognition of receipt of two successive bytes, is clocked into one of a plurality of shift registers. The length of each shift register represents the opposite of the position, within the expected sequence pattern, of the two successive bytes.Type: GrantFiled: February 7, 1995Date of Patent: December 31, 1996Assignee: Wandel & Goltermann Technologies, Inc.Inventor: Bradley T. Anderson

Patent number: 5566926Abstract: A resilient mounting system for safety barriers, including guardrails, hand rails, etc., includes a urethane rubber or other resilient material substantially between the periphery of the barrier and a floor or base. The barrier is biased against the base so as to provide an stiff yet resilient impact resistance that yields to absorb the energy of impact, such as from a vehicle, rather than requiring the structural material of the barrier itself to absorb and perhaps become dislodged or deformed by the impact. The resilient material can be shaped generally like the periphery of the barrier or it can be a standard shape that is replicated and arranged to engage a support for the barrier. A rail is resiliently mounted between two supports, the resilient mounting being arranged to permit limited relative movement between the rail and the supports but resisting removal of the rail from the supports.Type: GrantFiled: May 18, 1995Date of Patent: October 22, 1996Assignee: Voight Products IncorporatedInventor: William L. Voigt
