Method and apparatus are disclosed for mechanically opening a heat-bonded connection site between two hollow, flexible, thermoplastic segments of a medical fluid flow path, the heat-bonded connection site having an axis. The connection site is compressed between two facing surfaces, and the facing surfaces are relatively moved to rotate the connection site about the connection site axis and to apply force to the connection site substantially perpendicular to the connection site axis.

Provided are a method for manufacturing a structural body and a structural body, the structural body formed of FRP and having a high degree of freedom in cross-sectional shape even at a low cost. The method for manufacturing a structural body includes a winding step of forming a cylindrical laminate body LM by winding a plurality of composite materials including reinforcing fibers and an uncured thermosetting resin around a hollow cylindrical core member CY; a compressing step of winding a tape or film around an outer circumference of the laminate body LM and compressing the same; a preheating step of heating the laminate body LM until a state prior to complete curing of the thermosetting resin; and a main heating step of arranging the laminate body LM around which the tape or film is wound and the cylindrical core member in a molding die and pressing the same to thereby heat the laminate body LM until the thermosetting resin is completely cured while deforming the cylindrical core member CY to a non-circular cross-sectional shape. Thereby, a structural body in which the cylindrical core member CY and the laminate body LM are integrated can be formed.

A method for joining composite rods with tubular shape without expensive, machined connectors and without compromising the structural integrity of the composite rod includes internal and external collars applied to the ends of the composite rod and deformed via unidirectional compressive load applied by a clamp in the radial direction of the composite rod cross-section. The resulting plastic deformation of the metal collars and composite rod interlock those components to support both compressive and tensile loads. The deformed metal collars are easily joinable to other components via off-the-shelf hardware.

A method and apparatus of packing product in a tubular casing is provided. The method includes providing a continuous length of tubular casing, providing an expansion plug within the tubular casing, grasping the casing upstream end with a casing grabber, moving the casing grabber away from the expansion plug towards an outlet end of a product feed conduit, feeding product from the product feed conduit through the casing upstream end into the tubular casing, and cutting the tubular casing downstream of the product to sever an upstream casing segment from the remaining continuous length of tubular casing.

A method for the production of a suction jet pump delivering fuel into or out of a fuel tank, wherein the suction jet pump has a flow channel and a nozzle, and wherein the flow channel forms a feed line to the nozzle and the flow channel is formed in one piece with the nozzle, the method including, in the following order: placing a mold core into a matrix to produce the suction jet pump by injection molding and form a cavity between the mold core and the matrix; encapsulating the mold core and filling the cavity formed between mold core and matrix with a plastic; removing the mold core through an installation opening, arranged opposite the nozzle, in the flow channel; and closing the installation opening by thermal deformation, in the edge region of the installation opening, of the plastic used for the production of the suction jet pump.

A reusable surgical implement or template is provided that is formed of a core positioned within an enclosure. The core is formed of a suitable rigid, and optionally flexible material to enable the implant to conform to the desired use for the implement in a surgical procedure. The material forming the enclosure is also stretchable and flexible to accommodate the configuration and/or any flexing of the core, and is biologically inert to enable the implant to be sterilized after use for use in subsequent surgical procedures while protecting the material forming the core. The enclosure can be molded around the core in separate portions or components using multiple molding steps to form an enclosure with the desired attributes. The enclosure can also be preformed and the core inserted and secured within the enclosure using an adhesive to form the implement in an alternative manner.

Systems and methods are disclosed that include an operation chamber, a plasma generator having at least one plasma head disposed within the operation chamber and in proximity to a profile formed by cutting a piece of tubing, and a mechanical motion module. The plasma generator generates a plasma treatment and applies the plasma treatment via the at least one plasma head to the profile to activate material on an end surface of the profile, within a lumen of the profile, or a combination thereof. Once the material of the profile is activated by the plasma treatment, the mechanical motion module manipulates the profile to close the lumen of the profile to aseptically seal the profile.

A fluid transfer assembly is described. The fluid transfer assembly includes a unitary junction having an upstream portion and a downstream portion, the unitary junction defining a plurality of curved fluid pathways between the upstream portion and the downstream portion. The assembly also includes at least one flexible fluid conduit sealed to the junction in fluid communication with at least one of the plurality of curved fluid pathways.
