A positive crankcase ventilation system for an internal combustion engine routes blowby gases into the intake of the engine. Because the blowby gases have about 12% water vapor, during cold-weather operation, the water vapor may freeze in the PCV valve or in the port that couples the PCV duct with the intake manifold. In situations in which the PCV duct is pointing toward the direction of flow of the intake gases, a hood or cap is placed over the end of the tube according to the present disclosure. It can be as simple as a 90-degree elbow or multiple openings in the cap. A centerline of the openings is perpendicular or at an obtuse angle with respect to the direction of flow in the duct so that the intake gases do not directly access the openings and cause freezing in the openings (or ports).

The present invention provides a pressure control device for maintaining a constant predetermined pressure in a fluid dispensing container, as well as a pressure control system which includes the device. The present invention further concerns a method for manufacturing the pressure control device and system of the invention. The invention is of particular importance in the technical field of aerosol sprays.

The present disclosure relates to a battery module that includes a housing having a first protruding shelf along a first perimeter of the housing, a second protruding shelf along a second perimeter of the housing, where the first and second protruding shelves each include an absorptive material configured to absorb a first laser emission. The battery module also includes an electronics compartment cover configured to be coupled to the housing via a first laser weld, and a cell receptacle region cover configured to be coupled to the housing via a second laser weld. The electronics compartment cover has a first transparent material configured to transmit the first laser emission toward the first protruding shelf and the cell receptacle region cover has a second transparent material configured to transmit the first laser emission or a second laser emission toward the second protruding shelf.

The present invention is to provide a thermoplastic resin composition capable of obtaining a molded article that is excellent in appearance after laser welding and a color tone and has sufficient impact property as a resin member. In addition, the present invention is to provide a molded article that is excellent in appearance after laser welding and a color tone and has sufficient impact resistance as a resin member. As a result of intensive studies, the present inventors have found that the above problems can be solved by controlling a thermoplastic resin composition containing rubber-containing graft copolymer to have appropriate reflectance in the visible light and absorptivity in the near-infrared region, and have completed the present invention.

Methods are provided for manufacturing disposable diagnostic test elements via laser welding, where the methods include providing, in a stacked or layered arrangement, a base layer, a cover layer, and optionally an intermediate layer, where one of the layers is an absorbing layer and at least one other of the layers is a transparent layer, and where one of the layers includes a coating adapted to interact with a body fluid sample when conducting a test on the resulting test element; directing a laser beam in a weld area through the at least one transparent layer and against the absorbing layer; and fusing the transparent and the absorbing layers together to form the test element, where the coating covers the weld area at least in part and absorbs and/or scatters radiation from the laser beam at least in part. Disposable diagnostic test elements also are provided.

A resin composition for laser welding contains: relative to 100 mass parts of (A) a thermoplastic polyester resin material that contains a polybutylene terephthalate homopolymer and at least one of a polybutylene terephthalate copolymer, a polyethylene terephthalate resin, and a polycarbonate resin, 0.0005 to 0.5 mass parts of (B) nigrosine; and 0.01 to 2 mass parts of (C) a colorant containing at least an anthraquinone dye C1 having a maximum absorption wavelength in a range of 590 to 635 nm, a perinone dye C2 having a maximum absorption wavelength in a range of 460 to 480 nm, and an anthraquinone dye C3 having a maximum absorption wavelength in a range of 435 to 455 nm, at C1: C2:C3=24 to 41:24 to 39:22 to 46 as the mass ratio relative to 100 mass parts for a total of C1, C2, and C3.

A method of making a flowcell includes bonding a first surface of an organic solid support to a surface of a first inorganic solid support via a first bonding layer, wherein the organic solid support includes a plurality of elongated cutouts. The method further includes bonding a surface of a second inorganic solid support to a second surface of the organic solid support via a second bonding layer, so as to form the flowcell. The formed flowcell includes a plurality of channels defined by the surface of the first inorganic solid support, the surface of the second inorganic solid support, and walls of the elongated cutouts.

Provided is a polyamide resin composition that has a large light transmittance with respect to 940 nm laser beam, and is capable of yielding a molded article that is highly laser weldable; and a kit, a method for manufacturing a molded article, and a molded article, using such polyamide resin composition.

The present invention relates to an apparatus and method for joining a longitudinal seam in a tube, to an apparatus and method of joining a longitudinal seam in a tube in a borehole, to an apparatus and method of repairing a tube and to a pig. In an aspect an apparatus is provided for joining a longitudinal seam in a tube. The apparatus (200) includes a spool (202) for progressively unwinding a coiled member (10) into an extended form (12). The member (10) transitions from a flat form when coiled (11) to a slit tube form when extended (12), in which form the member is resiliently biased. A joining device (214) is positioned downstream of the spool arranged to provide energy to a portion of the member in its extended form to cause heating so as to progressively join together the longitudinal edges of the slit tube as the member passes the joining device. A longitudinal seam (20) is thereby formed in the tube.
