Foam of thermoplastic urethane elastomer composition and process for producing the foam
The method of the present invention for producing a urethane-based thermoplastic elastomer composition foam comprises the steps of:adding and mixing 0.1 to 30 parts by weight of carbon dioxide (B) to 100 parts by weight of a urethane-based thermoplastic elastomer composition (A) in a molten state, wherein said urethane-based thermoplastic elastomer composition (A) comprises a urethane-based thermoplastic elastomer (A-1) and other thermoplastic elastomer (A-2) in an (A-1) / (A-2) ratio of 20 / 80 to 99 / 1 by weight, to form a molten urethane-based thermoplastic elastomer composition (C) which is in a state of a mixture of the urethane-based thermoplastic elastomer composition (A) and the carbon dioxide (B) (gas dissolving step); andlowering a temperature of said molten urethane-based thermoplastic elastomer composition (C) (cooling step).The present invention can produce the urethane-based thermoplastic elastomer foam of stable quality over a range from low foamed product to highly foamed product by adding a given quantity of carbon dioxide in the molten urethane-based thermoplastic elastomer quantitatively and stably. It can also produce the foam excellent in flexibility, thermal insulation and surface appearances. It is also excellent in safety, because of use of carbon dioxide in place of the common foaming agent of fluorochlorohydrocarbon or butane, thus causing no air pollution or destruction of the ozone layer.

Composite tension rod terminal systems
InactiveUS6886484B2Superior combination of strengthSuperior combination of lightnessConnecting rodsRod connectionsFiberMechanical engineering
A composite tension rod is received in the sleeve portion of a shank that forms part of a terminal fitting, and is spaced from the shank sleeve and connected thereto by a potting resin. The shank sleeve wall tapers out from thin at its distal end to thick at the bury depth of the rod. The rod is tapered outwardly from a point of minimum diameter at its inner end to its full diameter a given distance from the end. The shank sleeve and rod have complementary dual tapering along said length such that as the diameter of the rod along said distance increases, the wall thickness of the shank sleeve decreases. The resin layer and the rod are secured to each other against relative longitudinal movement, as are the resin layer and the shank sleeve.In another aspect of the invention, a tension rod sleeve is fixed to the tension rod and extends over the distal end of the shank sleeve and along all or a majority of the length of the shank sleeve. The rod sleeve is tapered so that its wall thickness decreases to a minimum in the vicinity of the proximal end of the shank sleeve, or the rod sleeve, as it extends along the shank sleeve, is divided, or divides, into two halves or bands which join to form loop extending around a loop-engaging, convex, fiber-turnaround face formed on the terminal fitting. Such face extends transversely from one side to the other of the fitting.
