A plurality of polyurethane layers, some of which have a contrasting color with respect to an adjacent layer is formed into a laminate. During preparation, each layer is separately formed, as by spraying, and the contrasting color ensures that the preceding layer can be fully covered. The laminate can be utilized to cover areas or objects which are otherwise difficult to ensure that it has a continuous or complete coating. The invention is suitable for use as a coating and for the preparation of various in situ articles or enclosures, for example a fuel tank, such as commercial and military aircraft.

Method and apparatus for assembling a hose unit consisting of a given length of hose having end couplings inserted respectively in each of its ends. The given length is measured and cut off, being inserted freely, longitudinally in a rigid tube without endwise restraint. The couplings are inserted simultaneously, the thrust applied being balanced as well as sufficient to compress the hose longitudinally, while the dimensions of the tube relative to the hose are such as to prevent buckling. The rigid tube moves perpendicularly of the length of hose, preferably about a common axis, stepwise to a series of stations. In one station the inserted couplings are secured to the respective ends by a commercial crimper-expander. The hose unit is then dropped or ejected to a container. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.
