Socketing performance

Electrical Properties. Polysulfones offer excellent electrical insulative capabiUties and other electrical properties as can be seen from the data in Table 7. The resins exhibit low dielectric constants and dissipation factors even in the GH2 (microwave) frequency range. This performance is retained over a wide temperature range and has permitted appHcations such as printed wiring board substrates, electronic connectors, lighting sockets, business machine components, and automotive fuse housings, to name a few. The desirable electrical properties along with the inherent flame retardancy of polysulfones make these polymers prime candidates in many high temperature electrical and electronic appHcations. 

Socketing. Socketing of raising, erecting, or telescoping mast wire ropes shall be performed in accordance with practices outlined by API RP 9B. 

Performance of Cured Resin Sockets. Poured resin sockets may be moved when the resin has hardened. After ambient or elevated temperature cure recommended by the manufacturer, resin sockets should develop the nominal strength of the rope and should also withstand, without cracking or breakage, shock loading sufficient to break the rope. Manufacturers of resin socketing material should be required to test to these criteria before resin materials are approved for this end use. 

I, After the part is removed from the mold, it is often necessary to perform additional post-lit processing functions on the product. For example, holes may need to be drilled or protrusions cut off to create an opening into a storage tank. Some parts have very thin regions from which the polymer has to be removed, for example the eye socket of a plasticized polyvinyl chloride doll head. Sometimes multiple parts need to be affixed to one another using adhesives or [It. solvent adherents. 

In fact, there may be several implementations for each component, but the functional success of the overall scheme is dependent only on their specifications. The choice of implementation to plug in to each component socket is independent of the others (at least from a functional point of view—there may be performance or other couplings). 

Other Examination. All circumferential butt and miter groove welds shall be examined by 100% radiography in accordance with para. IP-10.5.2. Alternatively, when specified by the engineering design, ultrasonic examination 100% shall be performed in accordance with para. IP-10.5.5. Socket welds and branch connection welds that are not radiographed shall be examined by magnetic particle or liquid penetrant methods in accordance with para. IP-10.5.4 or IP-10.5.3. 

Some pH meters contain a pair of sockets at the back labeled K-F or Karl Fischer. When the manufacturer s instructions are followed, a constant current (usually about 10 pA) is applied across these terminals. To perform a bipotentiometric titration, Pt electrodes are connected to the K-F sockets. The meter is set to the millivolt scale, which displays the voltage needed to maintain the constant current between the electrodes. 

Two-way analysis of variance (and higher classifications) leads to the presence of interactions. If, for example, an additive A is added to a lube oil stock to improve its resistance to oxidation and another additive, B, is added to inhibit corrosion by the stock under load or stress, it is entirely possible that the performance of the lube oil in a standard ball-and-socket wear test will be different from that expected if only one additive has present. In other words, the presence of one additive may adversely or helpfully affect the action of the other additive in modifying the properties of the lube oil. The same phenomenon is clearly evident in a composite rocket propellant where the catalyst effect on burning rate of the propellant drastically depends on the influence of fine oxidizer particles. These are termed antagonistic and synergistic effects, respectively. It is important to consider the presence of such interactions in any treatment of multiply classified data. To do this, the two-way analysis of variance table is set up as shown in Table 1.24. 

Ball-and-socket joints should not be used for high-vacuum systems because they are not intended for vacuum work. It is possible to obtain specially made ball joints with O-rings that are acceptable for some vacuum work. Some manufacturers supply sockets that have not been ground, and when used in tandem with ball joints with O-rings, they can achieve satisfactory vacuum performance. 

When cables are to be sized for a particular project with regard to their short-circuit performance it is necessary to consider the let-through current of the protective device in the circuit e.g., fuse, circuit breaker. It is also necessary to determine whether the consnmer has fixed equipment such as a motor, or temporary equipment such as a portable tool plugged into a socket, because this establishes the minimum time dnration. This aspect is described in more detail when the earth-loop impedance is being considered, see sub-section 9.4.3.6.

When Ms. Olesky is asked to help with a new design, she works with her corporate laboratory to provide the best use for the fastener. She takes a fastener into a lab and applies force with a socket or drive bit until it breaks. "We drive at least 30 pieces to failure and perform statistical analysis, and that tells us how they re going to perform consistently," she says.

Replaceable parts - with a deteriorating socket In this case the part is replaced with a new one of the same type, bnt the rehabdity performance of the new part is not the same as for the original part -because the enviromnental and operational conditions have changed, or the interfaces with other items have deteriorated. 

Polliack et al. recently compared the accuracy, hysteresis, drift, and effect of curvature on sensor performance for these commercial prosthetic systems (force sensitive resistors F-Socket Measurement System, Tekscan, Inc., Boston, Mass. and Socket Fitting System, Rincoe, Golden, Colo prototype capacitive sensor. Novel Electronic, Minneapolis, Minn.). These authors concluded that the current systems were more appropriate for static use because the hysteresis, drift, and large standard deviations become more problematic during dynamic and long-term loading.

Vannah and Chlidress [7] applied similar techniques to measure the human calf, but confined the limb within a shell. They noted that stress relaxation occurred within one second of load application and no preconditioning effect was noted. Torres-Morenos et al. [6] performed a similar study, working through ports in quadrilateral sockets of three above-knee amputees. However, they found the mechanical properties of...
