Medical syringe, gasket for use in the syringe, and gasket production method
A gasket (13) for use in a medical syringe is provided, which includes a main body (14) made of an elastic material, and a lamination film (15) provided on a surface of the main body (14). The gasket (13) has a circumferential surface portion (17) to be kept in contact with an inner peripheral surface of a syringe barrel (11) of the syringe. The gasket (13) has a groove (22) provided in the circumferential surface portion (17) thereof as extending circumferentially thereof. The groove (22) has a depth of not less than 0.8D (m), preferably not less than D (m), wherein D (m) is the thickness of a portion of the lamination film (15) present in the circumferential surface portion (17) of the gasket (13).
Venting apparatus
A venting apparatus is disclosed herein. The venting apparatus comprises a substrate, such as a metal substrate or a specialty plastic substrate, having an opening therein and a fluoropolymer membrane, such as ePTFE, disposed over said opening and thermally bonded using a thermoplastic material to said substrate. This allows the fluoropolymer membrane to be directly bonded to the said substrate without using an adhesive layer.
Boss seal for composite overwrapped pressure vessel
A pressure vessel is disclosed. The pressure vessel may include a boss, a liner, an O-ring, and a composite overwrap of shell. A boss may comprise a through aperture, a first groove encircling the through aperture, and a first engagement mechanism. A liner may comprise an interior surface, exterior surface, and a second engagement mechanism. The interior surface may define an interior cavity of the pressure vessel. The second engagement mechanism may mechanically engage the first engagement mechanism to secure the liner to the boss. An O-ring may be positioned within the first groove of the boss and abut the exterior surface of the liner. A composite overwrap may surround the liner and at least a portion of the boss.
Method of producing aerofoils
The invention provides a method of molding composite material aerofoil, comprising steps of (i) providing a mold having the desired three-dimensional shape; (ii) providing a first layer over the mold that adheres to the mold and has a non-adhesive outer surface; (iii) applying composite material over the first layer; (iv) laying a moldable sheet over the composite material; (v) curing the resulting assembly and (vi) removing the moldable sheet and mold to leave an intact one-piece aerofoil structure.
NON-METALLIC HIGH PRESSURE HIGH TEMPERATURE HIGH CHEMICAL COMPATIBILITY FLANGE ISOLATION GASKET
A non-metallic flange isolation gasket kit sealing flanged pipeline connections and flanged vessel connections while providing electrical isolation protection between flanges suited for high-pressure and high-temperature cathodic protection applications is presented. The invention protects flange faces from media induced corrosion and mitigates flange rotation induced fatigue and failures. The invention comprises of a retainer, a seal, and a seal pre-load structural ring. The seal pre-load structural ring is inserted into the seal, and seal outer diameter surface is joined to the retainer inner diameter surface. A second embodiment comprises of a composite gasket blank, comprising of a retainer and a seal, and a seal pre-load structural ring. The seal outer diameter surface and the retainer inner diameter surface are joined by thermal fusion bonding. The invention may further comprise one or more gasket seating stress stabilizers and/or a centering ring. Tapered retainer upper and lower surfaces decrease flange rotation.
FORMING A RIGID CABLE HARNESS WITH A CURABLE SLEEVE
Provided are methods for forming a rigid cable harness. An example method includes providing a curable sleeve comprising a curable compound, an adhesive, and a backing; wherein the curable adhesive tape has a longitudinal direction. The method further includes placing a plurality of cables on the sleeve in the longitudinal direction and wrapping the curable sleeve around the placed plurality of cables to form a cable harness, wherein the wrapping comprises wrapping the plurality of cables with the curable sleeve in the longitudinal direction. The method additionally includes positioning the cable harness into a desired shape and curing the curable compound of the cable harness to form the rigid cable harness, wherein the rigid cable harness has the desired shape.
INCORPORATING SURFACE-MODIFIED COMPONENTS IN ADDITIVELY MANUFACTURED COMPONENTS
An additive manufacturing assembly may include a surface-modified component to be incorporated into an additively manufactured component by adhering the at least one component to the additively manufactured component during an additive manufacturing technique. The surface-modified component includes a modified surface that is modified to have increased adhesion to the additively manufactured component. The additive manufacturing assembly also includes means for additively forming layers of material using the additive manufacturing technique and a computing device, the computing device is configured to control the means for additively forming layers to form a layer of material on the surface of the surface-modified component and control the means for additively forming layers to form, on the layer of material, at least one additional layer of material to form the additively manufactured component incorporating the surface-modified component.
METHOD OF FABRICATING AN ELONGATE MEDICAL DEVICE
An elongate medical device having an axis comprises an inner liner, a jacket radially outward of the liner, a braid comprising metal embedded in the jacket, a sensor, and at least one wire electrically connected to said sensor. The at least one wire is one of: embedded in the jacket and optionally disposed helically around the braid; extending longitudinally within a tube which extends generally parallel to the device axis and wherein the tube is embedded in the jacket; and disposed within a lumen, wherein the lumen extends longitudinally within the jacket.
Sealing element and method of manufacture of a sealing element
Disclosed is a sealing element and a method of manufacture. The sealing element has a sealing surface for providing a seal against a contact surface. A sintered PTFE film is coupled to the elastomeric body, and defines the sealing surface, which is of particular suitability for a dynamic seal. The sealing film comprises a lubricious particulate material.
