The present disclosure relates generally to seal rings useful in rotating systems such as automobile transmissions, torque converters and automatic clutches. In one embodiment, the disclosure provides a seal ring in which the first end includes a platform in a radially inward portion of each lateral region thereof, and a vertically-extending blade in a radially outward portion of its central region; and the second end of the seal ring has two vertically extending fingers in a radially outward portion of each lateral region thereof, and a platform in a radially inward portion of its central region. When the ends are engaged, a portion of the extension of the blade is disposed radially directly over the central platform, a portion of each finger is disposed radially directly over a lateral platform, and the blade of the central region of the first end is disposed between the fingers.

A foam-based expansion joint seal system packaging which facilitates transport and reduces the need for internal splices.

A method for producing a sealing tape roll comprises the steps of providing a foam-barrier layer web comprising a plurality of foam strips, wherein a barrier layer is arranged between each pair of adjustment foam strips; applying a cover layer to the foam-barrier layer web; parting the cover layer in the longitudinal direction in an area of at least two foam strips and a certain distance away from each barrier layer adjacent to these foam strips, thus forming subsections of the cover layer, wherein a subsection of the cover layer at least partially covers two adjacent foam strips; and forming a sealing tape roll from the coated foam-barrier layer web.

The present disclosure relates generally to the field of medical instruments. More particularly, the present disclosure pertains to medical instruments for use with an endoscope, such as a biopsy cap and a biopsy cap housing with improved stability and stress distribution, for example, to securely attach to an endoscope biopsy port.

Biopsy caps and seals, and methods for making and using the same may be provided in conjunction with an endoscope assembly. A seal may include a main body including a circumferential outer wall surrounding a central lumen. The seal may include at least one support wall extending radially from the outer wall towards a center of the lumen, and at least one helical flap extending from the support wall helically downward along an inner surface of the outer wall, where the at least one helical flap defines an opening at the center of the lumen. The seal may alternatively include a plurality of projections extending radially inward from the outer wall towards a center of the lumen, where the plurality of projections are arranged in a series of circumferentially and angularly offset layers.

Attachments for endoscopes as well as methods for making and using attachments are disclosed. An example attachment may include a housing. One or more angled locking members may extend from an inner surface of the housing. The angled locking members may be designed to engage a biopsy port of an endoscope. One or more stabilizing members may extend from the inner surface of the housing. A locking apparatus may be coupled to the housing. A sealing member may be disposed within the housing.

The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to valve configurations providing sealable access for medical instruments to a working channel, such as a working channel for an endoscope.

The present disclosure relates generally to the field of medical devices such as endoscopes, endoscope assemblies, guide tubes, introducers, and instrument caps for endoscopes, guide tubes, and introducers. In particular, the present disclosure relates to biopsy cap configurations providing sealable access for medical instruments to a working channel, such as a working channel for an endoscope.

The present disclosure relates generally to the field of medical instruments. In particular, the present disclosure relates to a biopsy cap and endoscope biopsy cap housing with improved stability and stress distribution to securely and removably attach to an endoscope biopsy port. In one example, a biopsy cap housing may include a first center-split half comprising a first half of an upper and lower chamber and first pivot member, and a second center-split half comprising a second half of an upper and lower chamber, and second pivot member, wherein mating surfaces of the first and second center-split halves may be configured to interlock to define the upper and lower chambers.

A method for producing an extrusion molded product for automobiles, comprising the following steps: A synthetic resin injected into a first extrusion molding machine (21) is extruded through a first mold die (20) as a core material (3); the core material (3) passes through a first cooling tank (25), and then is bent by bending rollers (22) into a desired curved shape with a radius of curvature R1; the core material (3) is extended linearly, and goes into a second mold die (23); a thermoplastic elastomer injected in a second extrusion molding machine (24) forms seal portions (2) and seal lip portions (6) on a periphery of the core material (3); thereby forming a curved portion with a radius of curvature R2 on the extrusion molded product (1).
