Lead screw nuts having a body having a threaded opening having a thread region formed from a plurality of different materials having different properties, e.g., a thread region formed from a first material, such as a relatively low friction material, and a second material, such as a relatively high strength material (having thread portions formed from the first material and thread portions formed from the second material).

A method for preparing an article includes at least a first component of a polyolefin in conjunction with a second component of a polymer made by ring-opening metathesis polymerisation of norbornene type monomers. The method includes pre-treating a surface of the first component, applying a ring-opening metathesis polymerisable mixture of norbornene type monomers and a catalyst to the surface, and curing the ring-opening metathesis polymerisable mixture in contact with the surface, wherein the ring-opening metathesis polymerisable mixture has a η.sub.1000 at 30° C. of more than 9 sec. Articles such as a pipe line field joint or a protective element for a concrete tunnel lining element can be made using the method.

A neuromodulation catheter in accordance with a particular embodiment includes an elongate shaft and a neuromodulation element operably connected to the shaft. The shaft includes a proximal hypotube segment at its proximal end portion and a jacket disposed around at least a portion of an outer surface of the hypotube segment. The jacket may be made at least partially of a polymer blend including polyether block amide and polysiloxane. The neuromodulation element includes a distal hypotube segment and a tubular jacket disposed around at least a portion of an outer surface of the distal hypotube segment. The jacket has reduced-diameter segments spaced apart along its longitudinal axis. The neuromodulation element further includes band electrodes respectively seated in the reduced-diameter segments and respectively forming closed loops extending circumferentially around the jacket.

A golf flagstick device comprising a rigid support member combined with a plurality of jacks. The components are encapsulated by a material, such as a thermoplastic or thermosetting polymer, using an injection molding process. The jacks have one or more arms extending outward from a center portion. The arms are adapted to contact the inner wall of the mold's cavity to help hold the rigid support member in one place and away from the inner wall during the molding process. The flagstick includes a ferrule attached to a lower end which is adapted for placement into a putting cup and a tip fitting attached to an upper end which is adapted to be combined with a flag. The ferrule and/or tip fitting may be combined with the rigid support member before the injection molding process resulting in the ferrule and/or tip fitting being at least partially filled with and/or encapsulated by the material to help hold the components together without requiring a secondary attachment operation.

Acupuncture needles may be used for piercing tissue with less trauma than may occur when employing larger gauge needles. However, because acupuncture needles are fabricated and packaged differently than are larger gauge needles, acupuncture needles may be less compatible with certain manufacturing processes. Needle assemblies compatible with manufacturing processes may comprise a continuous support material having a plurality of apertures defined therein, and a first injection molded coupler that surrounds a proximal portion of an acupuncture needle and connects the acupuncture needle to a first location upon the continuous support material, such that the acupuncture needle is held in a pre-determined orientation with respect to a longitudinal axis of the first injection molded coupler. The acupuncture needles in adjacent apertures may also be spaced apart substantially uniformly.

Embodiments of the present disclosure provide a light emitting element and a processing apparatus therefor and relate to the technical field of light emitting devices. The light emitting element includes a light-emitting lamp bead(s), a connecting wire, and a covering member(s). The light-emitting lamp bead is welded to the connecting wire to form a welding joint. The covering member covers the light-emitting lamp bead and the welding joint. The covering member is integrally formed by injection molding. The present disclosure solves the technical problem existing in the prior art that the service life is adversely affected and the appearance is deteriorated because the welding joints are oxidized after a period of time.

A fuel injector, including a valve insert and a plug extrusion coating, is described, the valve insert including a valve sear and a valve housing. The valve housing has an alignment device, which is equipped to align the valve insert in an injection molding die, and the plastic extrusion coating has a second alignment device which is equipped to align the fuel injector during assembly in an internal combustion engine.

A catheter manufacturing method includes positioning a shaft in a cavity of a mold. The shaft is an elongated tubular body configured to be inserted into a living body. The mold includes a first mold die and a second mold die that contact one another to define a closed space which is the cavity. The method includes injecting a molding material into the cavity from a gate at a position between the proximal end and the distal end of the shaft in the axial direction. The injecting position is offset from the center of the shaft in the transverse direction. The method includes molding a hub onto the shaft by solidifying the injected molding material in the cavity onto the outer surface of the shaft.

The invention relates to a thermoplastic elastomeric bellow duct (10) having a corrugated duct segment (12) interposed between two elbowed segments (14, 18), wherein at least one of the elbowed segments (18) is made of thermoplastic elastomeric and connected to an end section (22) of the corrugated duct segment (12) by overmolding the elbowed segment (18) over the end section (22) of the corrugated duct segment (12), and wherein the end section (22) of the corrugated duct segment (12) includes a guiding and sealing arrangement (50) pointing away from the corrugated duct segment (12) in a radial direction (32). The invention further relates to an air duct (80) having such a thermoplastic elastomeric bellow duct (10).

An assembly process for assembling a basin using a molding tool operable between an open position and a closed position, the molding tool having a female molding insert, a male molding insert, and an insert jig, the female molding insert and the male molding insert cooperating to define a mold cavity when the molding tool is in the closed position, the female molding insert having an aperture, the insert jig having a sleeve and a cylinder, the cylinder repositionable within the sleeve and having an end with an end face and a pin protruding from the end face, includes applying adhesive to the pin. The assembly process also includes aligning the pin with an aperture of a basin rim insert. The assembly process also includes pressing the basin rim insert towards the end face such that the pin is received within the aperture of the basin rim insert.
