The change-in-length properties of synthetic fiber ropes are important for engineered applications. Unlike most other engineering components, typical synthetic fiber ropes have nonlinear, nonconstant change-in-length properties. These properties depend on variables such as rate and duration of tension application, and magnitude and number of previous tension applications. The length of a synthetic rope typically increases with each tension cycle. Thus ...

The change-in-length properties of synthetic fiber ropes are important for engineered applications. Unlike most other engineering components, typical synthetic fiber ropes have nonlinear, nonconstant change-in-length properties. These properties depend on variables such as rate and duration of tension application, and magnitude and number of previous tension applications. The length of a synthetic rope typically increases with each tension cycle. Thus strain-the ratio of change in length under tension to length before tensioning-has two different references. When overall change in length is of interest, strain must be referenced to the untensioned rope length before it was placed in service. But when rope stiffness under tension is of interest, the strain must be referenced to the untensioned length immediately before application of that tension. A clear unambiguous vocabulary of synthetic rope change in length properties is necessary. Different vocabularies were used in several recent rope test standards and design guidelines. This paper intends to explain the various vocabularies, propose a common vocabulary, and explain several pertinent concepts.
Large vessels such as tankers, LNG gas carriers and container ships have traditionally used steel wire ropes for mooring. These ropes are heavy, rust if not properly maintained and also suffer broken wires which make them difficult and hazardous to handle. Synthetic fibre ropes such as high modulus polyethylene (HMPE) offer a lightweight alternative to steel wire. When properly cared for they can long outlast steel wire ropes. They are lighter than wires, and they are easier and safer to handle by the ship's crew and by the berth mooring personnel. A problem which hinders the wide adoption of fibre rope mooring lines is their relatively poor resistance to external abuse and abrasion. They are particularly vulnerable to damage as they run through the ship's fairleads. This paper describes the development and use of a low- friction, low-abrasion nylon liner for use in ship fairleads. They can easily be retrofitted into existing fairleads onboard the vessel. They essentially eliminate wear on fibre mooring lines. This technology now enables the use of fibre mooring lines, with their significant safety advantages. This paper will be of interest to ship designers, owners and operators, especially for use on large tankers, gas carriers, container ships, and navy vessels.
A micro screw, a micro nut, an outer micro gear, an internal micro gear, a helical micro gear, a micro turbine-impeller and other micro mechanical parts are developed by utilizing extra fine wires. The extra fine wires are metallic wires or synthetic fibers which diameters are as small as 30 to 200 micrometers like a stainless wire, a tungsten wire, a copper wire, and a fluorocarbon thread. The micro screw is produced by coiling a pair of these wires around a needle pin without spacing, and by brazing the wires on the pin; besides, by peeling one wire from the brazed pin. Its pitch is less than 100 micrometers, and its major diameter is less than 600 micrometers. Other micro mechanical parts are also produced by same processes. In this paper, a novel manufacturing method for the micro mechanical parts utilized extra fine wires is developed, and several micro mechanical parts are produced as prompt products. Moreover, a micro positioning stage and reduction micro gear systems are developed as trial manufactures, and the micro turbine system is proposed as a new engine for the micro systems without electrostatic or magnetic drives.
With these test results, lightweight synthetic Plasma®12 × 12 rope has now proven its performance capabilities in large sizes suitable for use in the most demanding of operations. The “real-size data” created is significant in positioning high modulus synthetic ropes as a viable alternative to steel wire rope and chain in ultra-high strength applications. The tests conducted in May essentially validated the Cortland design and manufacturing processes, thereby enabling Cortland to publish a finalized product strength chart with confidence. Given the high modulus rope application success in smaller diameter applications, combined with the new interpretative knowledge gained during this testing, it is anticipated that a more rapid conversion from wire rope to synthetics in several critical lifting applications may be viewed in a more favorable light. Furthermore, Cortland has not reached the upper limit of the sizes that can be produced and will continue to test new sizes and materials.
The major growth area within the printed circuit market is expected to be as a result of the development of flexible and multi-layer circuits. The continuing pressures on designers of electrical and electronic equipment for smaller and lighter packaging has greatly increased the demand for thin, multi-layer and flexible, wiring packages. In the automotive field, dashboard wiring is rapidly being replaced with flexible circuitry. Computer, appliance and meter manufacturers are among the many circuit users finding benefits in flexible multi-layer circuitry. Mechanical pattern generation methods lend themselves to the production of flexible circuits, where the insulating film to which the pattern is bonded is tough, flexible, and possesses good electrical properties.
Evidence gathered to date clearly shows that moorings set far away from continental shores are subjected to severe fishbites. These bites occur from the surface to depths well within the bathypelagic zone, 1000 meters or more. The dimension of the fishbite problem is first reviewed. A data base which spans over twenty years and encompasses hundreds of moorings deployed world wide is used to delineate the space and time dependence of fishhbite attacks. This information is important when evaluating risks. Who are the culprits and why they do it is reviewed next. This knowledge is important when devising preventative methods. Granted that fishbite damage is a real possibility, how does one distinguish it from other plausible causes of rope failure? Observations, laboratory procedures, and rationales used to answer this question with a fair degree of assurance are described next. Finally the paper reviews the preventive and the curative methods which hopefully can protect mooring lines from the mechanical damage inflicted by fish teeth.
Fixed-pier berths for tankers and gas carriers are now sometimes installed and operated in locations exposed to waves and swell. In these conditions, the moored vessel can experience large motions which overload and fatigue mooring lines. Tails are short lengths of synthetic fiber rope which are placed in series with the vessel's winch-mounted wires to decrease mooring line stiffness and thus to reduce peak line loads and fatigue due to vessel motions. Past guidelines for conventional tankers and berths recommended the use of 1 lm long nylon tails on mooring lines. Those guidelines were developed many years ago when tankers were relatively small and when fixed-pier berths were located in protected harbors. But when such short nylon tails are used on large vessels at exposed berths, the mooring loads are high and the nylon tails tend to fatigue quickly and fail. Tension Technology International (TTI) recently conduced a study to investigate these problems and make recommendations for mooring lines and tails for use on modern large tankers and gas carriers, especially at exposed locations. The study assessed how waves influence vessel motions and line tensions and how tail length and material influence mooring line loads and fatigue. New recommendations were prepared for tail length and material for use at berths where vessel motions are significant. Large vessels can accommodate longer tail, and longer tail length decreases mooring line stiffness thus and reduces peak mooring line loads. Polyester rope is suffer than nylon, but longer polyester tails can achieve loads similar to short nylon tails. In some situations, polyester tails should be preferred, as that material has much better fatigue performance than nylon, especially in wet condition. Many vessels now use HMPE fiber rope mooring lines instead of wires. These HMPE mooring lines are essentially the same size and as strong as the wires they replace. They are much lighter and easier to handle and thus help crew safety. They are not as stiff as wire rope and thus reduce peak mooring line loads. The recommendations of this study are now published in mooring guidelines and used by tanker and gas-carrier operators.
From the point of view of the theories of electromagnetic wave transmission, electrochemistry and modification, a metallic modification technique possessed of not only low cost but also endowing flexible materials composed of synthetic fibre with high shielding effectiveness is put forward. Morphologies and element analysis of the modified samples, which are coated with copper film or copper and nickel-iron duplex film, are carried out by SEM and EDX The shielding effectiveness of the samples is tested within the incident electromagnetic wave frequency range of 0.1 MHz/spl sim/1000 MHz and 1.5 GHz/spl sim/18 GHz. Two kinds of nickel-plating methods are compared. The SE of the best sample is between -93 dB and -110 dB within the frequency range from 0.1 MHz to 1000 MHz. The value is up to the first grade of shielding. The SE value of the modified samples reduces while the incident frequency rises from 1.5 GHz to 18 GHz. The SE value of the sample with nickel-iron outer layer is better than that of the sample with single nickel outer layer.
We propose an artificial fiber (AF) pattern as a technique for embedding electrical information into paper. In order to adapt to more generic targets, we chose to embed information in fabric materials that are closely related to everyday life (such as clothes and bags). In this study, we examine a specific pattern (a traditional Japanese katagami pattern) for a kimono rather than a fiber pattern, and evaluate the adaptability to different photographic environments.
This paper discussed the development and detailing history of applied electrostatics which give advantages and disadvantages. Most electrical engineers, the term electrostatics brings to mind some hazy visions of early electrical experimentation involving an ancient Greek, a dead cat, and a piece of amber. Many of us recreated this quaint demonstration of triboelectric charging and its subsequent attraction in high school physics class. Perhaps some, in more enlightened schools, substituted modern materials such as plastics and synthetic fibers. In university electrical engineering programs, electrostatics is usually ignored or relegated to mathematical simplifications involving quasi-electrostatic approximations of important applications in electromagnetics. Meanwhile, a serious work involves the state-of-the-art study of topics such as electrodynamics and digital electronics. These fields have dominated so many important advances in the 20th century.
