Process for the manufacture of an impermeable connection between at least two fluid carrying silicone hose components and a fluid carrying assembly manufactured according to said process

In a process for the manufacture of an impermeable connection between at least two fluid carrying silicone hose components, the silicone hose components and a silicone connector component are first prepared. Afterwards a fluid silicone mass is applied to at least one connecting area where the silicone hose components abut on the silicone connector components. The at least one connecting area is post cured to harden the silicone mass. In a fluid carrying assembly with at least two fluid carrying silicone hose components and at least one silicone connector component, a fluid carrying connection is manufactured between these components by means of this process. This design results in a connecting technique that is, on the one hand, secure and, on the other hand, enables automation of the manufacture of an impermeable connection and thus of the fluid carrying assembly.

Molded hose with fabric layer

A reinforced hose includes an inner layer, a reinforcing intermediate layer, and an outer layer. The inner layer has and inwardly projecting sealing rib extending circumferentially on an inner surface thereof. The inner surface may also have an end stop to be engaged by a fitting received in the hose. The outer layer has a pair of annular clamp guides projecting outwardly which are axially spaced from an end of the hose. The sealing rib is positioned between the clamp guides to indicate an optimum location for a hose clamp.

Water pipe

A method of manufacturing a tubular woven hose cover includes feeding a plurality of longitudinal yarns into a weaving machine in an axial direction relative to the woven hose cover being made, weaving one or more radial yarns in and out of the plurality of longitudinal yarns in a radial direction relative to the woven hose cover being made, reducing a circumferential length of the one or more radial yarns and thereby generating a first cross-sectional diameter along a first portion of the woven hose cover, and increasing the circumferential length of the one or more radial yarns and thereby generating a second cross-sectional diameter along a second portion of the woven hose cover, wherein the first cross-sectional diameter is smaller than the second cross-sectional diameter.

ARTICLE WITH TUNABLE FLEXIBILITY USING REVERSIBLE CROSS-LINKING FLUIDS

A hose, connector, and hose assembly are described with mechanical properties that can be varied by exposure to specific energy stimuli. The hose has a wall with a first material, a second material, and one or more energy conduits, wherein the first material has a first rigidity with a first variability, and the second material has a second rigidity with a second variability, the first variability depends on energy emitted from the one or more energy conduits, and the second variability is substantially independent of energy emitted from the one or more energy conduits. The second material may be disposed in inclusions that are positioned in the wall. The connector connects two such hoses together, providing connectivity for the inclusions and the energy conduits of two lengths of hose. The connector also provides an external connection to couple an energy source to the energy conduits of the hose.
