In this manner spherical fiber aggregates are created, which combine different properties, and in particular are capable of absorbing humidity when used as a filler material, and therefore contain natural fibers, while on the other hand they do not lose their down-like properties, such as high bulk, compressive elasticity, softness, thermal insulation ability, light weight and ready adaptation to the body to be covered.

Abstract: The present invention provides a solution to the prior art problem of producing a high density papermakers batt fabric or felt which may be secured to an undamaged under layer in an economic manner. The present invention provides these improvements by providing a batt which is comprised of a non-woven low melt scrim to which the batt material is initially needled. Subsequent to producing a batt of the required density, the batt may, if desired, be needled or adhered to an under layer fabric.

In this manner, the batt and under layer fabric are unified to produce a multilayer papermakers felt with minimum effort and disruption of the under layer.

Abstract: A stretchable textile-like fabric comprising at least one layer of nonwoven fibers hydroentangled into a diamond shaped structure so that a substantial number of fibers are oriented equally on all sides of the diamond. This fiber orientation results in a balanced fabric structure. Subsequent to entangling the fibers, they are compacted so as to arrange the fibers into a series of wave-like configurations. The combination of the diamond shape fabric structure and the wave-like configurations of the fibers permits multi-directional stretch in the fabric when tension is applied. Additionally, when the tension in the fabric is released, the inherent memory of the fibers causes the fabric to return to its original form without substantial permanent deformation.

In a combustor a rib will run helically along the length of the interior of the combustor. When gases are swirling within the combustor, the pattern of the helix will be opposite to the pattern of the swirl.

Abstract: An adhesive sports tape windable about the handle of a sports appliance such as a tennis racquet to create a sheath thereabout which acts not only to enhance the grip of the handle but also as pneumatic cushioning minimizing the transmission of shock forces from the handle to the hand of the player. The tape is formed by a flexible band having an open-cell foam plastic core and opposing, gas-impermeable facing skins. The inner skin is coated with a pressure-sensitive adhesive layer to adhere the tape to the handle. The outer skin of the tape when the sheath is formed, is engaged by the hand of the player.
