An intrinsic gauging device for a ferrule type tube fitting of the type having a coupling nut, a coupling body and at least one ferrule, includes a precisely formed marking on the coupling nut that is visually perceptible that indicates the pull-up position of the tube fitting assembly.
Abstract:
An indicator device captured between couplers of ends of firehose sections that point to the source of the firehose and to safety. The preferred embodiment includes gasket-like annular body which fits over the male threads of the male coupler and is captured between annular ends of the abutting male and female coupler bodies. Direction pointing fingers, integral with the annular body, point backward toward the hose section to which the male coupler is attached and are angularly oriented to fit between longitudinal lugs of the male coupler.
Abstract:
A connector apparatus for controlling fluid dispensing/transmission that includes a control component for communication between couplers thereof. A first coupler has a transmitter, and is releasably connected with a mating reader coupler that has a transmitter and fluid control device to exchange information with the transmitter of the first coupler. The transmitters communicate and are operated by wireless means such as by RF devices. Upon confirming that the first coupler is properly coupled to the mating coupler and that the first coupler has a proper identification, the fluid control device controls fluid flow, using the transmitters of the first coupler and the mating reader coupler, under predetermined parameters, e.g., pressure, temperature, duration, and flow rate, as indicated in the first coupler.
Abstract:
Methods and apparatus for illumination of aerial refueling hoses are disclosed. In one embodiment, a conduit for transferring a flowable material includes a wall member. A plurality of reflective members are at least one of formed within an outer layer of the wall member and disposed on an outer surface of the wall member. The reflective members are adapted to at least partially reflect light incident thereon. In one aspect, the reflective members include reflective glass beads. In a further aspect, a first portion of the wall member has a first concentration of reflective members, and a second portion has a second concentration of reflective members.

Abstract:
A fluid coupling system is provided including a fluid coupling having a cooperative key coding system and latching mechanism, a valve biasing mechanism with corrosion resistance, and other advantageous features. The key coding system permits interconnection of only matched coupling members while preventing the inadvertent interconnection of mismatched coupling members notwithstanding the presence of many coupling, both matched and mismatched. The coupling includes first and second coupling members that are releasably slideably, axially interfitted with their passageways in fluid communication. The key coding system includes key coding elements on the coupling members that are axially movable into matched interengagement when the coupling members are matched but are precluded from moving into matched interengagement when they are mismatched, all without rotation of the couplings or the key coding elements irrespective of the relative rotational positions of the couplings members or coding elements. The latching mechanism is movable axially and radially of the coupling members between latching and unlatching positions, again without relative rotation of the latching mechanism and coupling members. The key coding system allows the latching mechanism to move into latching position when the key coding elements match but precludes such movement when there is a mismatch. Although the key coding system and the latching mechanism do not require rotation to function, they allow relative rotation of the coupling members. Furthermore, the coupling incorporates a valve biasing mechanism that does not use a metallic spring or other corrodible parts in contact with the corrosive chemicals.

Abstract:
A system for permanently associating identifying indicia with a previously manufactured product. Silicone sheet material having imbedded therein a quantity of thermally activatable crosslinking catalyst is secured to the product. An indici-containing element is placed on the silicone sheet material and is then covered by another piece of the same type of silicone sheet material. Heat is then applied to the assembly to cause the pieces of silicone sheet material to crosslink together and encapsulate the indicia-containing element.
Abstract:
A data resource specific to a pipe coupling centrally positioned within the coupling, intermediate the coupling ends. Multiple couplings are employed to connect together a string of well pipe. The data resource is adapted to be deployed at the coupling center in the space formed between the abutting ends of pipe made up into the coupling. The data resource provides information regarding the physical characteristics and locations of the coupling, the attached string pipe or the environment within which the coupling is disposed. The data resource may be a read-only component or it may be a readable and writeable component. The resource communicates with an instrument movable through the pipe and coupling. The data resource may be removably positioned at the center of the coupling or it may be permanently cemented in place. The data resource may take on the form of an annular ring with a crushable structure and suitable recesses for holding a data resource module. A circular communication antenna may be carried in the ring. A preferred form of the data resource is an externally threaded Teflon® ring equipped with axially extending resilient fingers. The resilient fingers are deformable upon engagement with the rotating ends of the pipe sections so that advancing the pipe sections beyond their optimum depth into the coupling deforms the fingers without rotating and thus displacing the ring. The body of the ring remains in the gap between the pipe and where it is protected from crushing.
