Abstract: Strips for use in forming flexible hoses from helically wound convolutions of the strip are disclosed, in which the strip has a substantially U-shaped body including a pair of radially projecting, spaced-apart walls connected by a transverse wall, and in which the body is produced from a polymeric material having a predetermined Young's modulus, and substantially the entire surface of the body is composed of that polymeric material, so that adjacent portions of the body can be directly bonded together to form a flexible hose upon the helical winding of the strip. Furthermore, supports are embedded in the pair of walls in order to reinforce the walls and permit the body to substantially retain its shape upon the application of external forces thereto. Methods for making flexible hoses from these strips are also disclosed.

Abstract: The elongated members used in making a spiral wound hose are formed from a relatively high melting structural material but provided with a more readily fusible melting buffer material, typically as a thin layer overlying the structural material. The molten bonding material applied to the elongated members during the spiral winding process bonds well with the buffer material. The hose has enhanced structural strength and integrity.

Abstract: This invention relates to an improved holder for tape that is wound about a tubular bar e.g., handle bar as for example, on a bicycle where the tape is fastened at the end of the handle bar. The holder comprises an expandable hub which can be inserted into the handlebar for expansion against the wall of the handle bar, the hub having a tapered aperture therein and a cylindrical core having a diameter slightly smaller than the tapered aperture at its largest opening and a larger diameter at its narrowest dimension for easy insertion into the hub. The core has a groove extending circumferentially about the exterior for defining a lip which can engage the end of the hub for providing a tight seal.

Abstract: This invention relates to an approved grip which is placed over a tubular handle bar such as for example on a bicycle handle bar. The grip comprises a tubular grip section having an outer shell and an inner expandable hub communicating with an end of the grip section. There is a space between the outer shell and inner hub so that the handle bar can be inserted into the grip section and between the outer shell and inner hub. The hub has an aperture tapering from its largest dimension at the end of the grip section communicating with said hub to its narrowest dimension at its other end. A cylindrical core having a diameter slightly smaller than the tapered aperture at its largest dimension and a larger diameter at its narrowest dimension has a groove extending circumferentially about the exterior for defining a lip section. When the core is inserted into the aperture, the hub is expanded and the lip section can engage the end of the hub and provide a tight seal.
