A pipe fitting having a first body and a second body that together at least partially define a fluid flow passage. The first body defines a first portion of the fluid flow passage that extends from a first end of the fluid flow passage to a first internal opening. The second body defines a second portion of the fluid flow passage that extends from a second internal opening to a second end of the fluid flow passage. The first body has a first interface surface that surrounds the first internal opening, the first interface surface having a plurality of anti-rotation grooves. The second body has a second interface surface that surrounds the second internal opening and engages with the first interface surface. The first internal opening is in fluid communication with the second internal opening. The second interface surface has a plurality of anti-rotation fingers that are each received by and engage with a corresponding one of the anti-rotation grooves. Rotation of the second body relative to the first body is resisted by the engagement of the anti-rotation fingers with the anti-rotation grooves.

Method and apparatus for joining at least two plastic parts

A method for joining at least two plastic parts (1, 5) along a predeterminable common joining point using infrared radiation (IR), is characterized in that each of the plastic parts (1, 5) to be joined is heated using infrared radiation at least along the joint by radiation sources without touching the respective plastic parts (1, 5). One radiation source is operated independently and spatially separated from the other radiation source. The radiation sources emit their respective infrared radiation to the respective plastic parts (1, 5) without contact and following the contour of the joint. The degree of heating by the respective infrared radiation is selected such that the joint is formed when the plastic parts (1, 5) are brought together.

APPARATUSES AND METHODS FOR SEAL CAP INSTALLATION

One example of the present disclosure relates to a form for supporting a volume of a viscous substance encapsulating at least a portion of an object while the viscous substance solidifies to form a seal. The form comprises a non-metallic solidified material; a distal axial opening; a proximal axial opening; and a lateral wall between the distal axial opening and the proximal axial opening. The lateral wall comprises an outwardly facing surface having a surface area, and at least one through lateral opening.

UNIVERSAL JOINT SEALING TAPE FOR DIFFERENT PROFILE DIMENSIONS AND SEAL ARRANGEMENT HAVING SUCH A JOINT SEALING TAPE

A joint sealing tape can be universally used for different profile dimensions, for sealing building joints, particularly for sealing them with regard to noise and/or smoke and with regard to fire. In particular, the joint sealing tape can be used for sealing a joint between a first component and a second component, having an elongated connection element and at least two sealing elements, which are positioned on the connection element at a distance from and next to one another, running in the longitudinal direction of the connection element, and wherein the connection element has a perforation.

METHOD FOR MANUFACTURING LONG MEMBER

A weather strip including a bottom wall, a first lateral wall and a second lateral wall and in which an angle between the bottom wall and the first lateral wall is constant and an angle between the bottom wall and the second lateral wall is partially varied in a longitudinal direction is manufactured. The method includes: a first step of pre-forming the angle of the first lateral wall and the angle of the second lateral wall to be constant and equal to or larger than final maximum angles; a second step of regulating a boundary between the bottom wall and the second lateral wall from moving toward the first lateral wall by a regulating member; a third step of partially varying the angle of the second lateral wall by a movable roller; and a fourth step of forming the angle of the first lateral wall by a fine-movable roller.

20230002965 · 2023-01-05 ·

A structural reinforcement for an article including a carrier that includes: (i) a mass of polymeric material having an outer surface; and (is) at least one consolidated fibrous insert having an outer surface and including at least one elongated fiber arrangement having a plurality of ordered fibers arranged in a predetermined manner. The fibrous insert is envisioned to adjoin the mass of the polymeric material in a predetermined location for carrying a predetermined load that is subjected upon the predetermined location (thereby effectively providing localized reinforcement to that predetermined location). The fibrous insert and the mass of polymeric material are of compatible materials, structures or both, for allowing the fibrous insert to be at least partially joined to the mass of the polymeric material. Disposed upon at least a portion of the carrier will be a mass of activatable material.

Seal member forming system and method
11707902 · 2023-07-25 · ·

A system and method for forming a seal member onto a substrate from a material is disclosed. The system includes a mold comprising an ultraviolet transmissible material, the mold having a first portion and a second portion operatively coupled to the first portion, the first portion having a first cavity, a second cavity, and a channel extending from an outer surface of the mold to the second cavity. The first cavity has a first shape that is complementary to a first side of the substrate and the second cavity has a second shape that is complementary to the seal member. The system also includes an applicator in fluid communication with the channel, where the applicator is configured to provide the material to the second cavity through the channel, and an ultraviolet irradiation device configured to irradiate the mold with ultraviolet light to cure the material when the material is provided to the second cavity, such that the seal member is formed on the substrate.

Injection-moulded component, joint, injection-moulding device, and method for producing an injection-moulded component

An injection-molded component having a casing body of plastics material and a core which is made of a core material, in particular of a metal, which is at least partially received within the casing body and is at least partially insert-molded. The injection-molded component may in particular serve as a joint part of a joint. As a result of the preferably metallic core, the injection-molded component, despite comparatively small dimensioning, is capable of being comparatively highly stressed. By virtue of the casing body of plastics material, a minor actuation noise may be implemented for the joint, even without complex lubrication.

Seal gasket element for a mixing apparatus, method for obtaining and applying the same, and special equipment for fitting the same

A method for obtaining and applying a sealing gasket element on a slide-valve sliding in a cavity of an apparatus for the recirculation and mixing of chemically reactive polymeric components, comprises the steps of: obtaining from an elastic-plastic material a precursor element of the seal element, with a grid structure having a reticular shape; positioning the precursor element around the slide-valve; exerting on the precursor element, through temporary clamping elements, a radial compression and contraction action to insert it and couple it to one or more housing seats provided on the slide-valve so as to obtain the seal element well coupled to the latter; progressively removing the clamping elements to sequentially release successive parts of the gasket element and gradually free the slide-valve to gradually introduce the parts of the slide-valve—freed in succession—in the housing cavity allowing the sealing gasket element to gradually expand radially due to the elastic return by adhering tightly to the inner surface of the same housing cavity. The special equipment for fitting the sealing gasket element on the slide-valve and the so obtained recirculation and mixing apparatus is also described.
