Appl. No.:

6/531945

International Classification:

B23K 3512

US Classification:

285287

Abstract:

A braided hose which has a frost-free socket joint made by placing a ring of brazing material above the joint and heating the joint below the ring. This way, the brazing material flows into the joint so that its external and exposed edge of the joint is completely filled. If the capillary action of the molten solder is incomplete, any voids in the joint are exposed to the interior of the hose and not to the atmosphere. The socket is very shallow, in the order of one-half to one convolution of the hose.

International Classification:

US Classification:

285149

Abstract:

Twin seals are provided between an end fitting and a convoluted hose connected thereto. The end fitting has two parts, one of which terminates in an elongated member having large and coarse threads on the outside thereof. As the elongated member is turned into the end of the hose, convolutions at the end of the hose are either scrunched and squeezed together or stretched over a ramp section. One of the seals is along the surface of the large threads and the other is a result of the end thrust either the scrunching and squeezing or the stretching of the end convolutions. A pilot end of braid on the hose pulls it to increase the end thrust. In some embodiments, a third seal is made between the outside surface of the hose and a gland surrounding the hose. The pitch of the large and coarse threads may be longer than the pitch of the convolutions so that an inner core of the hose advances faster than the outer braid, as the elongated member is turned into the end of the core thereby increasing either the scrunching and squeezing or the stretching.

Titeflex Corporation - Springfield MA

International Classification:

F16L 1110

US Classification:

138109

Abstract:

A high pressure (up to 8000 psi service) hose assembly has an inner core made of "Teflon" PTFE, covered by a "Kevlar" aramid reinforcing braid. The PTFE can, but the aramid cannot, withstand the attack of oils and other fluids which may be conveyed through the hose. Therefore, the aramid is covered by PTFE tape and the end of the hose is sealed inside an end fitting. In one embodiment, when the end fitting is swaged or otherwise manipulated to capture the hose, the PTFE inner core extrudes to complete the sealing of the hose end.
