Bio-degradable means (100) for use as drinking straw, stirrer and chop stick and a method (200) for making the bio-degradable means (100) is provided. The bio-degradable means (100) includes at least one dried leaf strip (100S) configured to be at least one of straight rolled and spiral rolled along an entirety of an elongated guide member R to facilitate formation of an elongated bio-degradable means (100). The dried leaf strip (100S) is at least one of a coconut tree leaf strip, palm tree leaf strip and a plantain leaf strip. A bonding agent is applied at at least one edge portion of each dried leaf strip (100S) with respect to a length wise direction of the dried leaf strip (100S) to maintain the elongated bio-degradable means (100) in rolled position.

A hose extrusion mandrel for manufacturing rubber hoses includes: a solid thermoplastic, elongate core; and a rubber compound outer layer covering a surface of the elongate core. A ratio between a diameter of the core and a thickness of the rubber compound layer may be between 8 and 11.

A composite drill pipe including an inner pipe having a first diameter, an outer pipe having a second diameter greater than the first diameter, and a plurality of flow channels formed between the inner pipe and the outer pipe. The plurality of flow channels are formed by a plurality of walls extending radially between an outer diameter of the inner pipe and an inner diameter of the outer pipe. A method of forming a composite drill pipe includes pultruding a drill pipe comprising an inner pipe having a first diameter, an outer pipe having a second diameter greater than the first diameter, and a plurality of flow channels formed between the inner pipe and the outer pipe. The method also includes providing a multi-directional reinforcement over an outer diameter of the outer pipe.

A method for producing hoselines having at least the following working steps: a) providing a hoseline or pipeline blank (1, 2, 3) of at least one elastomeric and/or thermoplastic base material in a production device, while reinforcing elements may be embedded in the base material; and b) introducing an RFID structure (4, 4A, 4B, 4C) into the outer layer (3) of the hoseline or pipeline blank (1) in the axial direction parallel to the longitudinal axis of the hoseline or pipeline blank (1) and synchronously with the feed rate of the production device, the RFID structure having at least one carrier (4A) and the RFID structure (4, 4A, 4B, 4C) having RFID chips (4B) securely arranged on the carrier (4A) at predetermined spaced intervals.

A composite lumen includes a braided structure infused with an impermeable elastic sealer. The braided structure has an inner diameter of 3 mm or less and a braid angle greater than 100°. The braided structure also has a wall thickness to inner diameter ratio greater than 0.02, picks per inch from between about 25 and about 135, and a number of ends between about 12 and about 48, with a braid pattern that is selected from 1×1, 2×2, or 2×1 and with an effective yarn denier (yarn denier×ply number) greater than 45.

Fluid transfer assemblies for transferring fluid into or out of a single vessel and distributing the fluid to multiple other vessels are provided. The fluid transfer assemblies are customizable, substantially aseptic, and single-use. The fluid transfer assemblies may be manufactured by solidifying polymeric materials to form a body around a mandrel with protrusions engaged to fluid conduits and leaving recesses in the solidified polymeric material to stretch the resultant body and remove the mandrel with protrusions. The resultant fluid transfer assembly may be surrounded by a rigid housing and valves may be engaged with the conduits and/or body to control the fluid flow within the fluid transfer assembly.
